Kamienie pęcherza moczowego
Objawy

Kamienie pęcherza moczowego (calculi vesicae urinariae) to twarde złogi mineralne powstające w wyniku krystalizacji minerałów w skoncentrowanym moczu, najczęściej u pacjentów z zaburzeniami opróżniania pęcherza. Objawy kliniczne obejmują ból w dolnej części brzucha, dyzurię, częstomocz, krwiomocz oraz trudności w oddawaniu moczu, a także objawy związane z zakażeniem układu moczowego (ZUM), takie jak gorączka i mętny mocz. Diagnostyka opiera się na badaniu moczu, obrazowaniu (RTG, TK, USG) oraz cystoskopii. Czynniki sprzyjające formowaniu kamieni to m.in. zaleganie moczu, zakażenia, pH moczu oraz niedostateczne nawodnienie. Szczególnie narażone są grupy pacjentów z przerostem gruczołu krokowego, uszkodzeniem rdzenia kręgowego, długotrwałym cewnikowaniem oraz po plastyce pęcherza.

Kamienie pęcherza moczowego – definicja

Kamienie pęcherza moczowego (łac. calculi vesicae urinariae) to twarde złogi mineralne, które formują się w pęcherzu moczowym. Powstają, gdy minerały zawarte w skoncentrowanym moczu krystalizują i łączą się ze sobą, tworząc kamienie. Zjawisko to najczęściej występuje, gdy pacjent ma trudności z całkowitym opróżnianiem pęcherza moczowego.12 Kamienie te mogą mieć różną wielkość – od małych złogów przypominających piasek aż po duże formacje wielkości piłki golfowej.34

Objawy kamieni pęcherza moczowego

Małe kamienie pęcherzowe mogą nie powodować żadnych objawów, zwłaszcza jeśli są wystarczająco małe, aby zostać wydalone z pęcherza podczas mikcji.12 Jednak większość pacjentów z kamieniami pęcherza moczowego doświadcza objawów, ponieważ kamienie podrażniają ścianę pęcherza lub blokują przepływ moczu.12

Typowe objawy

Do najczęstszych objawów kamieni pęcherza moczowego należą:123

  • Ból w dolnej części brzucha – często o dużym nasileniu; u mężczyzn może również występować ból w obrębie lub wokół prącia, moszny, krocza, pleców lub bioder123
  • Ból lub dyskomfort podczas oddawania moczu (dyzuria) – może mieć charakter pieczenia lub ostrego bólu12
  • Częste oddawanie moczu (częstomocz) – szczególnie w nocy12
  • Trudności z oddawaniem moczu lub przerywany strumień moczu12
  • Krew w moczu (krwiomocz)12
  • Mętny lub ciemny mocz o nietypowym zabarwieniu12

Szczegółowe objawy związane z kamicą pęcherza

Oprócz typowych objawów, pacjenci mogą również doświadczać:12

  • Uczucia niepełnego opróżnienia pęcherza po mikcji1
  • Nagłego parcia na mocz – uczucia pilnej potrzeby oddania moczu12
  • Niezdolności do oddawania moczu z wyjątkiem przyjęcia określonych pozycji ciała12
  • Nietrzymania moczu – mimowolnego wyciekania moczu12
  • Przerywania strumienia moczu – mocz może nagle przestać płynąć podczas mikcji, co często wiąże się z bólem12
  • Drobnych złogów („piasku” lub „żwiru”) wydalanych z moczem12

Objawy specyficzne u mężczyzn

U mężczyzn mogą występować dodatkowe objawy:12

  • Ból lub dyskomfort w obrębie prącia12
  • Bóle promieniujące do moszny12
  • Nagłe ustanie oddawania moczu z pewnym stopniem bólu odniesionego do czubka prącia, moszny, krocza, pleców lub biodra12

Objawy związane z zakażeniem układu moczowego

Kamienie pęcherza moczowego często przyczyniają się do rozwoju zakażeń układu moczowego (ZUM). Objawy ZUM mogą obejmować:12

  • Gorączkę (czasami z dreszczami)12
  • Nieprzyjemny zapach moczu12
  • Mętny mocz12
  • Nasilone objawy dysuryczne (ból podczas oddawania moczu)12

Progresja kamieni pęcherza moczowego

Przebieg choroby związanej z kamieniami pęcherza moczowego może być różny, w zależności od wielkości i liczby kamieni, a także od przyczyny ich powstawania.12

Naturalny przebieg

Małe kamienie pęcherza moczowego mogą zostać wydalone samoistnie podczas mikcji, często bez powodowania wyraźnych objawów.12 Jednak w większości przypadków kamienie pęcherza, które nie zostały wydalone, wymagają interwencji medycznej.12

Kamienie mogą stopniowo gromadzić coraz więcej kryształów mineralnych, stając się większymi i trudniejszymi do wydalenia z czasem.12 Nawet jeśli początkowo nie powodują objawów, mogą z czasem zacząć podrażniać ścianę pęcherza lub blokować przepływ moczu.12

Czynniki wpływające na progresję

Szybkość formowania się i wzrostu kamieni pęcherza moczowego zależy od kilku czynników:12

  • Ilość materiału krystalicznego obecnego w moczu12
  • Stopień zakażenia układu moczowego13
  • Zdolność do opróżniania pęcherza – im większe zaleganie moczu, tym większe ryzyko formowania się kamieni12
  • pH moczu – może wpływać na formowanie się określonych typów kamieni12
  • Nawodnienie – niedostateczne nawodnienie sprzyja tworzeniu się kamieni12

Powikłania nieleczonych kamieni pęcherza moczowego

Nieleczone kamienie pęcherza moczowego mogą prowadzić do szeregu powikłań:12

  • Przewlekłe problemy z pęcherzem – długotrwałe trudności z oddawaniem moczu, takie jak ból lub częste oddawanie moczu12
  • Nawracające zakażenia układu moczowego – kamienie pęcherza mogą być przyczyną powtarzających się zakażeń bakteryjnych12
  • Całkowita blokada odpływu moczu – kamień może utknąć w ujściu pęcherza do cewki moczowej i zablokować przepływ moczu, co stanowi stan nagły wymagający natychmiastowej interwencji12
  • Uszkodzenie pęcherza – chroniczne podrażnienie ściany pęcherza może prowadzić do jej zgrubienia i bliznowacenia12
  • Uszkodzenie nerek – w przypadku długotrwałego utrzymywania się kamieni i związanych z nimi zakażeń12
  • Rozerwanie pęcherza moczowego – w skrajnych przypadkach, gdy kamień całkowicie blokuje odpływ moczu i pęcherz się przepełnia12

Grupy zwiększonego ryzyka

Niektóre grupy pacjentów są bardziej narażone na rozwój kamieni pęcherza moczowego oraz związanych z nimi powikłań:12

  • Mężczyźni po 50. roku życia – szczególnie z przerostem gruczołu krokowego12
  • Pacjenci z uszkodzeniem rdzenia kręgowego – 36-67% pacjentów z uszkodzeniem rdzenia kręgowego rozwija kamienie pęcherza12
  • Pacjenci z długotrwałym cewnikiem – ok. 2,2% tych pacjentów rozwija kamienie pęcherza12
  • Pacjenci po plastyce pęcherza – 2-44% dorosłych i 4-53% dzieci po tego typu zabiegach rozwija kamienie pęcherza12

Diagnostyka kamieni pęcherza moczowego

Przy podejrzeniu kamieni pęcherza moczowego przeprowadza się szereg badań diagnostycznych:12

  • Badanie moczu – do wykrycia mikroskopowych ilości krwi, bakterii i zmineralizowanych kryształów; badanie to pozwala również zidentyfikować zakażenie układu moczowego, które może być przyczyną lub skutkiem kamieni pęcherza12
  • Badania obrazowe – w tym RTG, tomografia komputerowa lub ultrasonografia jamy brzusznej i miednicy12
  • Cystoskopia – bezpośrednia wizualizacja wnętrza pęcherza za pomocą cienkiej rurki z kamerą na końcu12

Kiedy szukać pomocy medycznej

Należy skonsultować się z lekarzem, jeśli wystąpi którykolwiek z następujących objawów:12

  • Utrzymujący się ból w podbrzuszu12
  • Częstsze oddawanie moczu, zwłaszcza w nocy12
  • Krew w moczu12
  • Trudności z oddawaniem moczu lub przerywany strumień moczu12
  • Gorączka z objawami zakażenia układu moczowego12

Należy natychmiast udać się na oddział ratunkowy w przypadku:12

  • Silnego bólu w okolicy pęcherza moczowego12
  • Całkowitej niemożności oddania moczu pomimo silnego parcia12
  • Narastających objawów – zwłaszcza przy współistnieniu gorączki i bólu12

Rokowanie

Rokowanie w przypadku kamieni pęcherza moczowego jest zazwyczaj dobre, pod warunkiem odpowiedniego leczenia:12

  • Większość kamieni pęcherza można usunąć lub rozpuścić bez trwałego uszkodzenia pęcherza12
  • Przy właściwym leczeniu kamienie pęcherza nie powodują długoterminowych problemów zdrowotnych12
  • Mogą jednak nawracać, jeśli przyczyna ich powstawania nie zostanie wyeliminowana12
  • Nieleczone kamienie mogą prowadzić do bólu, trudności z oddawaniem moczu, krwawienia i zakażenia12

Szczególnie istotne jest leczenie chorób podstawowych, które przyczyniają się do powstawania kamieni pęcherza, takich jak przerost gruczołu krokowego u mężczyzn, aby zapobiec nawrotom.12

    Stones, especially tiny ones, may not cause any symptoms. Stones in the bladder may cause pain in the lower abdomen. Stones that obstruct the ureter or renal pelvis or any of the kidneys drainage tubes may cause back pain or renal colic. Renal colic is characterized by an excruciating intermittent pain, usually in the area between the ribs and hip on one side, that spreads across the abdomen and often extends to the genital area. The pain tends to come in waves, gradually increasing to a peak intensity, then fading, over about 20 to 60 minutes. The pain may radiate down the abdomen toward the groin or testis or vulva. […] Other symptoms include nausea and vomiting, restlessness, and sweating. There may be blood or a stone or a piece of a stone in the urine. A person may have an urge to urinate frequently, particularly as a stone passes down the ureter.

  • #1 Common Symptoms of Bladder Stones in Pets and How to Treat Them
    https://www.ballantynevet.com/blog/bladder-stones-in-pets/
    Bladder stones can come with different symptoms in pets, the most common indicators being: […] Straining to urinate […] Frequent urination […] Blood in the urine […] Urinary accidents […] Licking genital area. Often, these symptoms come with changed behaviors, as well. You’ll notice either a change of appetite in your pet usually a decrease as well as some vomiting and even weight loss if the issue has been left untreated for some time. If left untreated, bladder stones can lead to serious health complications. One of the biggest risks is partial or complete urinary tract obstruction, where the stones block the flow of urine from the bladder, causing severe discomfort in your pet. In some cases, urinary tract obstruction can lead to potentially serious complications like kidney damage. Untreated bladder stones can also increase the risk of developing secondary health issues like urinary incontinence, leakage, and UTIs that keep coming back. Over time, chronic bladder stone formation can cause structural damage to the urinary tract, which leads to scarring and a thickening of the bladder wall. This can be painful and seriously diminish your pet’s quality of life. Living with pain is something no pet should have to go through, so getting them checked for bladder stones and treating them promptly is essential.

Symptoms include discomfort, and diagnosis typically involves urinalysis, imaging (x-ray, computed tomography, or ultrasound), and cystoscopy. Bladder stones cause specific symptoms and are a significant source of patient discomfort. Bladder stones may not present with any specific symptoms or may be asymptomatic. They are typically associated with conditions that cause incomplete bladder emptying, most commonly BPH. Patients may also experience a combination of urinary symptoms such as terminal hematuria, suprapubic pain, weak stream, dysuria, and more. Terminal gross hematuria with sudden cessation of voiding is a common sign of a large bladder calculus. Bladder stones can also cause urinary incontinence, dysuria, vesicovaginal fistulas, and outflow obstruction. About 66% of adult patients with bladder stones, particularly those with larger calculi (4 cm), will experience overactive bladder symptoms. However, in some cases, the only symptom may be recurrent UTIs. If left untreated, bladder stones can lead to urinary tract damage, recurrent stone formation, bladder damage, urinary retention, or infection. Bladder stones, particularly larger calculi, can lead to various complications, including frequent urination, hematuria, urinary obstruction, pain, possible association with bladder cancer, urethral obstruction, urinary retention, and urinary tract infections.

    Bladder stones are hardened mineral clumps that form in your bladder. They develop when pee remains in your bladder for a long time. The most common symptom is abdominal pain, but it can also cause problems peeing. […] You may not notice small bladder stones. They may leave your body when you pee without any symptoms. Larger bladder stones may be so painful that you may feel sick to your stomach, aren’t able to pee and have other symptoms, such as bloody urine. Go to the nearest emergency room (ER) if you have bladder stone signs, including severe pain, difficulty peeing and other worsening symptoms. […] You may pee out smaller bladder stones without any obvious symptoms. Large bladder stones can irritate your bladder and cause intense pain, bleeding and problems peeing. Signs and symptoms of a larger bladder stone may include: Changes in the color of your pee. Your pee may look cloudy or dark. You may also see blood in your pee (hematuria). Frequent urges to pee. You may feel like you always need to pee, even if you just went. Pain. It’s common to feel pain or a burning sensation when you pee (dysuria). You may also feel pain that comes and goes in the lower part of your abdomen (belly), penis or testicles. Stopping and starting when you pee. You may have a difficult time starting to pee and maintaining a strong flow, even if you really have to go. Sometimes your pee stream stops and starts (urinary intermittency). Urinary tract infections (UTIs). Bladder stones often cause UTIs. UTI symptoms include frequent, painful urination. Your pee may also be cloudy and smelly.

    Bladder stones may cause no symptoms at all, explains Dr. Jo Myers, a veterinarian on Vetster. Small stones may be expelled in the urine without complications, and a large stone may stay in the bladder without causing any problems. When present, clinical signs of stones in dogs may include: Blood in urine, Frequent urination, often in small amounts, Straining to urinate, Dribbling urine or having accidents, Painful urination or vocalizing when urinating, Excessive licking of the genitals. […] Symptoms of bladder stones are similar to those of other urinary conditions. The only way to know if a dog has stones is to see a veterinarian for diagnostic testing. […] Bladder stones are not emergencies themselves, but they can lead to emergency complications. If a stone becomes stuck in the urethra after it leaves the bladder when a dog urinates, the subsequent urinary obstruction is a medical emergency. Symptoms of a urethral obstruction in dogs include: Inability to urinate or straining unproductively, Vocalizing in pain when trying to urinate, Much smaller flow of urine than normal, Vomiting, Lethargy. […] A blockage in the urinary tract stops urine flow, causing urine to back up and toxins to accumulate. This is life-threatening and can quickly lead to kidney damage. A urinary blockage requires emergency treatment from a veterinarian.

Rough-surfaced stones can damage the bladder tissue, creating new surfaces for additional stone formation. The presence of bacteria in stones may indicate a concurrent bladder infection. […] The most common secondary condition associated with urolithiasis is urinary obstruction. This can occur when a stone becomes lodged in the narrow urethra on its way out of the bladder, resulting in a blockage. Stones that become stuck can partially or completely obstruct the flow of urine. […] Horses that have bladder stones should be assessed for stones elsewhere in the urinary system. Although less common, some horses may also have stones in their kidneys or ureters (tubes connecting the kidneys to the bladder). Kidney stones can lead to chronic kidney failure.
