Kamienie pęcherza moczowego
Zapobieganie i profilaktyka

Kamienie pęcherza moczowego stanowią istotne wyzwanie kliniczne wymagające kompleksowej profilaktyki obejmującej zarówno modyfikację stylu życia, jak i farmakoterapię, zwłaszcza u pacjentów z grup wysokiego ryzyka nawrotów. Kluczowym elementem jest odpowiednie nawodnienie zapewniające produkcję 2-3 litrów moczu na dobę, co zmniejsza ryzyko krystalizacji składników mineralnych. Zaleca się także technikę podwójnego mikcji oraz u mężczyzn z łagodnym rozrostem gruczołu krokowego oddawanie moczu w pozycji siedzącej. Dieta powinna być dostosowana do składu chemicznego kamieni: dla kamieni wapniowych zaleca się spożycie 1000-1500 mg wapnia dziennie, ograniczenie sodu do 4-5 g/dobę oraz umiarkowane białko zwierzęce (0,8-1,0 g/kg mc/dobę), natomiast w kamicy moczanowej wskazana jest alkalizacja moczu do pH 6,0-7,5 oraz ograniczenie puryn. U pacjentów z nawracającą kamicą stosuje się farmakoterapię, m.in. diuretyki tiazydowe (chlortalidon 25-50 mg/dobę, indapamid 2,5 mg/dobę), cytrynian potasu (5-12 g/dobę), allopurinol (100-300 mg/dobę) czy tiopronin w kamicy cystynowej.

Profilaktyka i zapobieganie kamieni pęcherza moczowego

Kamienie pęcherza moczowego stanowią istotny problem kliniczny, który wymaga nie tylko skutecznego leczenia, ale również wdrożenia odpowiednich strategii profilaktycznych. Zapobieganie tworzeniu się kamieni pęcherza moczowego skupia się zarówno na modyfikacji stylu życia, jak i farmakologicznym wsparciu, szczególnie u pacjentów z grupy wysokiego ryzyka nawrotów12. Wczesne rozpoznanie i leczenie stanów predysponujących do tworzenia kamieni jest kluczowe dla efektywnej profilaktyki3.

Podstawowe strategie profilaktyczne

Najważniejszym elementem profilaktyki kamieni pęcherza moczowego, niezależnie od ich składu chemicznego, jest odpowiednie nawodnienie organizmu14. Zaleca się przyjmowanie zwiększonej ilości płynów, głównie wody, w ilości zapewniającej produkcję 2-3 litrów moczu na dobę56. Odpowiednie nawodnienie zmniejsza koncentrację składników mineralnych w moczu, co redukuje ryzyko ich krystalizacji i tworzenia złogów7. Badania wykazały, że zwiększone spożycie wody może zmniejszyć nawroty kamicy o 55% i wydłużyć czas do nawrotu kamicy7.

Kolejnym istotnym elementem profilaktyki jest regularne opróżnianie pęcherza moczowego1. Zaleca się stosowanie techniki podwójnego mikcji, czyli oddawanie moczu ponownie po 10-20 sekundach od pierwszej próby, co zwiększa skuteczność opróżniania pęcherza58. U mężczyzn z powiększonym gruczołem krokowym zaleca się także oddawanie moczu w pozycji siedzącej, co może poprawić opróżnianie pęcherza98.

Profilaktyka w grupach wysokiego ryzyka

Pacjenci z wysokim ryzykiem kamicy pęcherza moczowego wymagają szczególnej uwagi i zindywidualizowanego podejścia profilaktycznego6. Dotyczy to zwłaszcza osób z przebytymi epizodami kamicy, zaburzeniami anatomicznymi układu moczowego lub schorzeniami predysponującymi do tworzenia kamieni10.

U pacjentów z łagodnym rozrostem gruczołu krokowego zaleca się leczenie farmakologiczne (alfa-blokery, inhibitory 5-alfa-reduktazy) lub chirurgiczne w celu zmniejszenia ciśnienia wywieranego na pęcherz moczowy i poprawy odpływu moczu1110. W przypadku niecałkowitego opróżniania pęcherza (np. w pęcherzu neurogennym) może być konieczne stosowanie cewnikowania11.

U pacjentów z uchyłkami pęcherza moczowego lub wypadaniem pęcherza moczowego (cystocele) może być wskazane leczenie chirurgiczne w celu poprawy anatomii układu moczowego i zapobiegania zastojowi moczu11. W przypadku nawracających zakażeń układu moczowego konieczne jest ich skuteczne leczenie i profilaktyka12.

Dieta i modyfikacje stylu życia

Modyfikacje dietetyczne odgrywają istotną rolę w profilaktyce kamicy pęcherza moczowego, szczególnie u pacjentów z określonymi typami kamieni134. Zalecenia dietetyczne różnią się w zależności od składu chemicznego kamieni i indywidualnych czynników ryzyka pacjenta4.

W przypadku kamieni wapniowych zaleca się1415:

  • Dietę o normalnej zawartości wapnia (1000-1500 mg dziennie, około 2-3 porcje nabiału dziennie)
  • Ograniczenie spożycia sodu (4-5 g dziennie)
  • Umiarkowane spożycie białka zwierzęcego (0,8-1,0 g/kg masy ciała dziennie)
  • Unikanie nadmiernej suplementacji witaminy C

1615

W przypadku kamieni szczawianowo-wapniowych dodatkowo zaleca się ograniczenie spożycia produktów bogatych w szczawiany, takich jak szpinak, rabarbar, kakao, orzechy czy herbata1718. Warto pamiętać, że jednoczesne spożywanie produktów zawierających wapń i szczawiany sprzyja wiązaniu tych związków w przewodzie pokarmowym, co zmniejsza ich wchłanianie i wydalanie z moczem19.

W przypadku kamieni moczanowych zaleca się2021:

  • Ograniczenie spożycia produktów bogatych w puryny (czerwone mięso, podroby, owoce morza)
  • Dietę o niskiej zawartości białka zwierzęcego
  • Alkalizację moczu (docelowe pH moczu 6,0-7,5 lub wyższe)

2022

Ogólne zalecenia dietetyczne dla wszystkich pacjentów z kamicą pęcherza moczowego obejmują zwiększone spożycie warzyw i owoców, szczególnie cytrusowych (ze względu na zawartość cytrynianów), pełnoziarnistych produktów zbożowych oraz ograniczenie spożycia soli, cukru i napojów zawierających kofeinę232425.

Farmakologiczne metody profilaktyki

W przypadku pacjentów z wysokim ryzykiem nawrotów kamicy, u których modyfikacja stylu życia i diety nie przynosi oczekiwanych rezultatów, stosuje się farmakologiczne metody profilaktyki2627.

W profilaktyce kamieni wapniowych stosuje się2817:

  • Diuretyki tiazydowe (np. chlortalidon 25-50 mg/dobę, indapamid 2,5 mg/dobę), które zmniejszają wydalanie wapnia z moczem
  • Cytrynian potasu (5-12 g/dobę), który zwiększa poziom cytrynianów w moczu i hamuje tworzenie kamieni wapniowych

2827

W profilaktyce kamieni moczanowych stosuje się2027:

  • Cytrynian potasu lub wodorowęglan sodu w celu alkalizacji moczu
  • Allopurinol (początkowo 100 mg/dobę, stopniowo zwiększając do 100 mg trzy razy dziennie) w przypadku hiperurykozurii
  • Febuksostat jako lek drugiego rzutu w przypadku hiperurykozurii

2227

W przypadku kamieni cystynowych stosuje się20:

  • Cytrynian potasu w celu alkalizacji moczu (docelowe pH moczu 7,0-7,5 lub wyższe)
  • Tiopronin (alfa-merkaptopropyloglikolinę) lub penicylaminę, które zmniejszają stężenie cystyny w moczu

2027

Regularne monitorowanie i kontrola

Regularne monitorowanie i kontrola pacjentów z przebytą kamicą pęcherza moczowego stanowią istotny element profilaktyki nawrotów2629. Zaleca się regularne wykonywanie badań moczu, w tym oceny pH moczu, ciężaru właściwego oraz obecności kryształów2930.

U pacjentów z nawracającą kamicą pęcherza moczowego lub wysokim ryzykiem nawrotów zaleca się wykonanie 24-godzinnej zbiórki moczu w celu oceny wydalania składników litogennych, takich jak wapń, szczawiany, kwas moczowy, cytrynian i magnez2631. Na podstawie wyników tych badań możliwe jest opracowanie zindywidualizowanej strategii profilaktycznej32.

Regularne badania obrazowe, takie jak USG pęcherza moczowego lub RTG układu moczowego, umożliwiają wczesne wykrycie nawrotów kamicy, zanim doprowadzą one do objawów klinicznych3334.

Szczególne grupy pacjentów

Profilaktyka u pacjentów z zaburzeniami neurologicznymi

Pacjenci z zaburzeniami neurologicznymi, takimi jak uszkodzenie rdzenia kręgowego czy pęcherz neurogenny, stanowią grupę szczególnie narażoną na rozwój kamieni pęcherza moczowego3536. W tej grupie kamice pęcherza moczowego występuje u 19-39% pacjentów z niecałkowitym uszkodzeniem rdzenia kręgowego i 36-67% pacjentów z całkowitym uszkodzeniem rdzenia kręgowego35.

W profilaktyce kamicy pęcherza moczowego u tych pacjentów zaleca się36:

  • Regularne i kompletne opróżnianie pęcherza moczowego (cewnikowanie w regularnych odstępach czasu)
  • Utrzymywanie objętości moczu w pęcherzu poniżej 400 ml
  • Regularne płukanie pęcherza moczowego
  • Zwiększone spożycie płynów
  • Leczenie i profilaktykę zakażeń układu moczowego

3536

Profilaktyka u pacjentów z cewnikiem na stałe

Pacjenci z cewnikiem założonym na stałe są szczególnie narażeni na rozwój kamicy pęcherza moczowego – kamienie pęcherza moczowego występują u około 2,2% tych pacjentów35. W tej grupie pacjentów zaleca się37:

  • Codzienne czyszczenie cewnika i wymianę worków do zbiórki moczu co tydzień
  • Regularne płukanie pęcherza moczowego
  • Zwiększone spożycie płynów
  • Profilaktykę zakażeń układu moczowego

3537

Profilaktyka u dzieci

W przypadku dzieci z kamicą pęcherza moczowego szczególną uwagę należy zwrócić na nawodnienie organizmu oraz odpowiednią dietę3538. Zaleca się38:

  • Spożycie wody w ilości odpowiadającej co najmniej połowie masy ciała dziecka w uncjach (np. dziecko ważące 80 funtów powinno wypijać co najmniej 40 uncji wody dziennie)
  • Ograniczenie spożycia mięsa, soli i produktów bogatych w szczawiany
  • Utrzymanie odpowiedniej podaży wapnia w diecie

38

W przypadku pierwotnych (endemicznych) kamieni pęcherza moczowego u dzieci zaleca się utrzymanie odpowiedniego nawodnienia, unikanie biegunki oraz zbilansowaną dietę zawierającą zboża, mleko oraz suplementy witamin A i B, z dodatkiem jaj, mięsa i gotowanego mleka krowiego po pierwszym roku życia35.

Nowoczesne podejście do profilaktyki

Współczesne podejście do profilaktyki kamicy pęcherza moczowego opiera się na zindywidualizowanej ocenie ryzyka i dostosowaniu strategii profilaktycznej do potrzeb każdego pacjenta3932. Kluczowe znaczenie ma identyfikacja czynników ryzyka metabolicznego, które można modyfikować poprzez odpowiednie leczenie26.

Nowoczesne metody profilaktyki obejmują3240:

  • Kompleksową ocenę metaboliczną (badania krwi i moczu, 24-godzinna zbiórka moczu)
  • Analizę składu chemicznego kamieni
  • Szczegółową ocenę nawyków żywieniowych i stylu życia
  • Opracowanie zindywidualizowanego planu profilaktycznego
  • Regularne monitorowanie efektów leczenia i modyfikację planu w zależności od potrzeb

3932

Warto podkreślić, że kamienie pęcherza moczowego mogą być objawem innych schorzeń, takich jak zespół metaboliczny, cukrzyca czy choroby układu sercowo-naczyniowego3927. Dlatego kompleksowa profilaktyka powinna uwzględniać również leczenie tych chorób towarzyszących27.

Podsumowanie zaleceń profilaktycznych

Podsumowując, najważniejsze zalecenia profilaktyczne w kamicy pęcherza moczowego obejmują4127:

Zalecenie Szczegóły Korzyści
Zwiększone spożycie płynów 2-3 litry dziennie, głównie woda Rozcieńczenie moczu, zwiększenie diurezy, wypłukiwanie kryształów
Regularne opróżnianie pęcherza Technika podwójnego mikcji, unikanie zatrzymywania moczu Zmniejszenie czasu kontaktu kryształów z błoną śluzową pęcherza
Zbalansowana dieta Bogata w owoce i warzywa, z ograniczeniem soli i białka zwierzęcego Korzystny wpływ na skład i pH moczu
Utrzymanie normalnej masy ciała Regularna aktywność fizyczna, zdrowa dieta Zmniejszenie ryzyka chorób metabolicznych predysponujących do kamicy
Leczenie chorób towarzyszących Leczenie łagodnego rozrostu prostaty, zakażeń układu moczowego, wad anatomicznych Eliminacja czynników predysponujących do tworzenia kamieni
Farmakoterapia Leki specyficzne dla danego typu kamieni (diuretyki tiazydowe, cytrynian potasu, allopurinol) Normalizacja parametrów biochemicznych moczu, zapobieganie krystalizacji
Regularne monitorowanie Badania moczu, badania obrazowe, kontrole urologiczne Wczesne wykrycie nawrotów i modyfikacja leczenia

Należy podkreślić, że skuteczna profilaktyka kamicy pęcherza moczowego wymaga ścisłej współpracy pacjenta z lekarzem oraz przestrzegania zaleceń dotyczących diety, nawodnienia i farmakoterapii19. Wdrożenie odpowiednich strategii profilaktycznych może znacząco zmniejszyć ryzyko nawrotów kamicy i poprawić jakość życia pacjentów7.

    https://www.aafp.org/pubs/afp/issues/2019/0415/p490.html
    Measures to prevent recurrence of kidney stones include lifestyle modifications, citrate supplementation, and medications. Lifestyle modifications are the cornerstone of prevention after a first kidney stone in patients with low risk of recurrence, whereas citrate supplementation and medications are reserved for patients with recurrent stones. Patients at high risk of stone recurrence should receive preventive measures tailored to the results of the metabolic assessment. […] The most important lifestyle modification to prevent recurrent kidney stones is to increase fluid intake to 2.5 to 3 L per day to guarantee diuresis of 2 to 2.5 L per day and a urine specific gravity lower than 1.010. Fluids should be consumed throughout the day and should consist of beverages with a neutral pH. Decreasing intake of carbonated drinks, especially those acidified with phosphoric acid (e.g., colas), further reduces risk of stone recurrence.
  • #7 Water for preventing urinary stones
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7012319/
    Increased water intake may decrease stone recurrences (RR 0.45, 95% CI 0.24 to 0.84; 199 participants; low certainty evidence); this corresponds to 149 fewer (43 fewer to 205 fewer) stone recurrences per 1000 participants with 270 stone recurrence per 1000 participants over five years in the control group. […] Increased water intake may also prolong the time to urinary stone recurrence compared to standard water intake (HR 0.40, 95% CI 0.20 to 0.79; 199 participants; low certainty evidence); based on a stone recurrence rate of 270 per 1000 participants over five years, this corresponds to 152 fewer (209 fewer to 50 fewer) recurrences per 1000 participants.

    Because a range of medical conditions can cause bladder stones, there are no specific ways to prevent them. […] Drinking plenty of fluids will help break down any developing stones. Experts recommend drinking at least 8 cups of water a day. […] Some people with urinary tract infections may feel like there is urine left in the bladder after urinating. In these cases, it is best to try urinating again 10-20 seconds after the first attempt. This is called double voiding and can help prevent stones from forming. […] A 2014 meta-analysis suggests that if a person has an enlarged prostate, sitting down to urinate can help make sure that the bladder is completely emptied. This may help prevent or slow the buildup of bladder stones.

    https://en.wikipedia.org/wiki/Bladder_stone
    The best way to prevent bladder stones is to drink plenty of liquids. Juices containing citrate are thought to reduce the risk of stone formation. A study published in the Clinical Journal of the American Society of Nephrology indicate orange juice is more effective at preventing stone formation than other citrus juices. […] Men who have difficulty with urination due to prostate enlargement should seek treatment, however, urinating in a sitting position appears to improve bladder emptying which might decrease the risk of bladder stones forming. […] Prevention in newborn children, especially in the first three months of life when most stones begin, is critical. Studies show that feeding newborn infants milk (mother’s, cow or goat) with no substitutes or supplements until at least the third month has proven successful in preventing most stones.

    Bladder outlet obstruction remains the most common cause of bladder calculi in adults. Prostatic enlargement, elevation of the bladder neck, and high postvoid residual urine volume cause stasis, which leads to crystal nucleation and accretion. This ultimately results in overt calculi. In addition, patients who have static urine and develop urinary tract infections are more likely to form bladder calculi. […] Aggressive treatment of lower urinary tract symptoms with alpha-blockers and 5-alpha-reductase inhibitors should further decrease the overall incidence of bladder stones by improving bladder emptying. Removal of bladder stones will continue to progress toward minimally invasive techniques, thus decreasing hospital stay and recovery times. Continued advances in surgical equipment and the ability to downsize without the sacrifice of effectiveness could eventually render open surgery for stones obsolete.

    In a person who has passed a calcium stone for the first time, the likelihood of forming another stone is about 11% at 2 years, and 39% at 15 years. Measures to prevent the formation of new stones vary, depending on the composition of the existing stones. […] Drinking large amounts of fluids 8 to 10 ten-ounce (300-milliliter) glasses a day is recommended for prevention of all stones. People should drink enough fluid to produce more than about 2 quarts of urine per day. Other preventive measures depend somewhat on the type of stone. […] People with calcium stones may have a condition called hypercalciuria, in which excess calcium is excreted in the urine. For these people, measures that decrease the amount of calcium in the urine can help prevent formation of new stones. One such measure is a diet that is low in sodium and high in potassium. Calcium intake should be about normal 1,000 to 1,500 milligrams daily (about 2 to 3 servings of dairy per day). The risk of a new stone forming is actually higher if the diet contains too little calcium, so people should not try to eliminate calcium from their diet. However, people may need to avoid sources of excess calcium, such as antacids that contain calcium.

    Extra sodium causes you to lose more calcium in your urine. […] To prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, beer/alcoholic beverages, meat-based gravies, sardines, anchovies and shellfish. […] Drink plenty of fluid: 2-3 quarts/day […] Limit foods with high oxalate content […] Eat enough dietary calcium […] Avoid extra calcium supplements […] Eat a moderate amount of protein […] Avoid high salt intake […] Avoid high doses of vitamin C supplements.
  • #16 EAU Guidelines on Urolithiasis – Uroweb
    https://uroweb.org/guidelines/urolithiasis/chapter/metabolic-evaluation-and-recurrence-prevention
    Excessive intake of oxalate-rich products should be limited or avoided to prevent high oxalate load, particularly in patients who have high oxalate excretion. […] Animal protein should not be consumed in excess and limited to 0.8-1.0 g/kg body weight. Excessive consumption of animal protein has several effects that favour stone formation, including hypocitraturia, low urine pH, hyperoxaluria, and hyperuricosuria. […] Calcium should not be restricted, unless there are strong reasons for doing so, due to the inverse relationship between dietary calcium and stone formation. The daily requirement for calcium is 1,000 to 1,200 mg. […] Daily sodium (NaCl) intake should not exceed 4-5g. High intake adversely affects urine composition: Calcium excretion is increased by reduced tubular re-absorption; urinary citrate is reduced due to loss of bicarbonate; increased risk of sodium urate crystal formation.

    Thiazide diuretics, such as chlorthalidone or indapamide, also reduce the concentration of calcium in the urine in such people. Potassium citrate may be given to increase a low urine level of citrate, a substance that inhibits calcium stone formation. Restricting animal protein in the diet may help reduce urinary calcium and the risk of stone formation in many people with calcium stones. […] A high level of oxalate in the urine, which contributes to calcium stone formation, may result from excess consumption of foods high in oxalate, such as rhubarb, spinach, cocoa, nuts, pepper, and tea, or from certain intestinal disorders (including some kinds of weight loss surgery). Calcium citrate, cholestyramine, and a diet that is low in fat and in oxalate-containing food may help to reduce urinary oxalate levels in some people. Pyridoxine (vitamin B6) decreases the amount of oxalate the body makes.

    Prevention of kidney stones may include a mix of lifestyle changes and medicines. […] You may lower your risk of kidney stones if you: […] Drink water throughout the day. This is the most important lifestyle change you can make. If you’ve had kidney stones before, your healthcare professional may tell you to drink enough fluids to pass about 2.1 quarts (2 liters) of urine a day or more. […] Eat fewer oxalate-rich foods. If you tend to form calcium oxalate stones, your healthcare professional may recommend limiting foods rich in oxalates. […] Choose a diet low in sodium and animal protein. Lower the amount of sodium you eat. […] Keep eating calcium-rich foods, but use caution with calcium supplements. Calcium in food doesn’t have an effect on your risk of kidney stones. […] Ask your healthcare professional to refer you to a dietitian. The dietitian can help you make an eating plan that lowers your risk of kidney stones. […] Medicines can control the amount of minerals and salts in the urine. They may be helpful in people who form certain kinds of stones. The type of medicine that your healthcare professional prescribes depends on the kind of kidney stones you have.

    One of the best measures you can take to avoid kidney stones is to drink plenty of water, leading you to urinate a lot. So, be sure to keep well hydrated, especially when engaging in exercise or activities that cause a lot of sweating. […] Moderating intake of these foods may be beneficial for people who form calcium oxalate stones, the leading type of kidney stones. […] It is important to eat and drink calcium and oxalate-rich foods together during a meal. In doing so, oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form. […] Don’t reduce the calcium. Work to cut back on the sodium in your diet and to pair calcium-rich foods with oxalate-rich foods. […] Research conducted by Dr. Jhagroo shows that those with kidney stones do not always heed the advice of their nephrologists and urinary specialists. About 15% of kidney stone patients didn’t take prescribed medications and 41% did not follow the nutritional advice that would keep stones from recurring. Without the right medications and diet adjustments, stones can come back, and recurring kidney stones also could be an indicator of other problems, including kidney disease.

    Uric acid stones are almost always caused by excessive acid levels in the urine. Potassium citrate should be given to all people who have uric acid stones to make the urine alkaline and neutralize the high acid levels that cause uric acid stones. Occasionally, a low animal protein diet or allopurinol may be used to reduce uric acid levels in the urine. Maintaining a large fluid intake is also very important. […] For stones made of cystine, urinary cystine levels must be kept low by maintaining a large fluid intake and sometimes taking alpha-mercaptopropionylglycine (tiopronin) or penicillamine. […] People with recurrent struvite stones may need to take antibiotics continually to prevent urinary tract infections. Acetohydroxamic acid may also be helpful in people with struvite stones.

    To prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, and shellfish, and follow a healthy diet that contains mostly vegetables and fruits, whole grains, and low fat dairy products. Limit sugar-sweetened foods and drinks, especially those that contain high fructose corn syrup. Limit alcohol because it can increase uric acid levels in the blood and avoid crash diets for the same reason. Eating less animal-based protein and eating more fruits and vegetables will help decrease urine acidity and this will help reduce the chance for stone formation.

    Given the high recurrence rate in stone disease, development of preventive strategies to minimize recurrence is almost as important as the treatment of an individual stone. […] Any patient who has had at least one stone should have a few basic tests including serum labs to check for systemic causes of stones and a stone analysis to determine stone composition. Patients with recurrent stones or those at high risk for recurrence should perform a 24-hour urine test (Litholink) to tailor preventive strategies to their individual risks. […] Because many risk factors for kidney stones are diet related, nutritional changes are the cornerstone of any stone prevention strategy. Stone patients should increase fluid intake to 2 to 2.5 liters per day. Additionally, other common recommendations include a low salt diet, moderate calcium intake, low animal protein diet, low oxalate diet, and increased dietary citrate. […] Medication therapy such as thiazide diuretics and alkalinization medications may also be used for stone prevention. Generally, these are started following a trial of dietary changes in high-risk patients or those with stone recurrence based on persistent risk factors noted on 24-hour urine testing.

    Bladder stones will form in 3-4.7% of men undergoing surgery for benign prostatic obstruction (BPO) [720,721], 19-39% and 36-67% of motor-incomplete and motor-complete spinal cord injury patients, respectively [722], and 2.2% of patients with long-term catheters [723]. […] The metabolic abnormalities which predispose patients to form secondary bladder stones are poorly understood. Stone analysis of 86 men with a BPO-related bladder stone demonstrated that 42% had calcium-based stones (oxalate, phosphate), 33% had magnesium ammonium phosphate, 10% had mixed stones and 14% had urate stones [711]. […] Low urine volume (poor hydration) is the most consistently demonstrable abnormality [729-731]. […] Regular bladder irrigation reduces the chances of bladder stone recurrence in adults and children with bladder augmentation or continent cutaneous urinary diversion and adults with spinal cord injury who perform CISC (see section 6.4.5 Special Situations) [773,778,803]. […] In children with primary (endemic) bladder stones maintenance of hydration, avoidance of diarrhoea, and a mixed cereal diet with milk and Vitamins A and B supplements, with the addition of eggs, meat, and boiled cows milk after one year of age are recommended to prevent a recurrence [729].

    Bladder stones are common in people with a spinal cord injury a 2006 study from Kessler Institute for Rehabilitation states that bladder stones are the second most common urological complication in people with SCI (urinary tract infections are the first). The Kessler study says that approximately 36 percent of people using indwelling catheters develop stones within eight years. […] One of the ways to help reduce the risk of bladder stones is to make sure you are completely emptying your bladder. Residual urine left in the bladder allows minerals in the urine to crystallize and can lead to stones. It also provides a Petri dish for bacteria to grow into a UTI. […] The steps you can take to reduce the chance of developing a bladder stone or at least catch it in its early stages are the same steps for all good bladder health. Get a yearly urology exam. If you have an indwelling catheter or bladder augmentation, be sure to irrigate to flush out mucus. Catheterize on a regular basis and make sure your bladder is fully drained to avoid stagnant urine. Catheterize often enough to keep your bladder volumes less than about 400cc (about 1.7 cups). Last, but never least, drink plenty of fluid water is best to stay hydrated and help flush everything out of the bladder. The rule of thumb is, drink enough fluid to keep your pee clear to straw colored.

    There are things you can do to help prevent kidney stones from forming. The best ways to do that depends on the type of stone produced, underlying risk factors and how willing your child is to stick with a long-term prevention plan. Your child may need to change certain habits, such as drinking more fluids and changing his diet. […] We recommend children with stone disease: […] Drink a minimum of half of their body weight in ounces of water daily. For example, an 80-pound child would drink 40 oz. of water each day. Proper hydration helps prevent the urine from becoming concentrated with crystals, which can lead to stones forming. It also reduces the risk for urinary tract infections, which can cause struvite stones. […] Limit meat, salt and foods high in oxalate, such as green leafy vegetables, chocolate and nuts. Do not limit calcium in your child’s diet. Doing this can actually increase the risk of kidney stones. […] We also may give your child medication to prevent kidney stones.

    All stone formers, independent of their individual risk, should follow the preventive measures in Table 4.5. The main focus is the normalisation of dietary habits and lifestyle risks. Stone formers at high risk need specific prophylaxis for recurrence, which is usually pharmacological treatment based on stone analysis and urinary risk profile. […] An inverse relationship between high fluid intake and stone formation has been repeatedly demonstrated. The beneficial effect of fruit juices is mainly determined by the presence of citrate or bicarbonate. Citrus fruit juices seem to protect against stone disease either by increasing urinary citrate levels or by having an alkalinising effect on it. […] A common-sense approach to diet should be taken, that is, a mixed, balanced diet with contributions from all food groups, without any excesses. Sufficient calcium intake is needed especially in vegetarian and vegan diets.
