Tuberculosis of bladder
Medical necessity for the diagnosis and treatment of bladder TB is established by the presence of signs and symptoms suggestive of the condition, along with supporting laboratory and imaging findings.The medical record should clearly document the rationale for diagnostic testing and the chosen treatment approach, including medication regimens and surgical interventions.
Physicians diagnose bladder TB based on symptoms, medical history (including prior TB), blood tests, tuberculin skin tests, and imaging studies like intravenous urography, MRI, or CT scans. Definitive diagnosis is confirmed through tissue biopsy or samples showing acid-fast bacilli (AFB). Treatment involves antituberculous medications, and surgery may be necessary to address complications like abscesses, tuberculomas, or fistulas.
In simple words: TB of the bladder is a type of tuberculosis infection that affects the bladder. It happens when TB bacteria spread from the lungs to the bladder, usually through the blood.It can cause problems with urinating, like pain, burning, and needing to go more often. If left untreated, it can lead to more serious problems in the urinary system.
Tuberculosis (TB) of the bladder is a form of extrapulmonary tuberculosis that arises when Mycobacterium tuberculosis (or rarely, Mycobacterium bovis) bacilli spread from an initial infection site, typically the lungs, to the renal system via the bloodstream or lymphatic system.The infection may lie dormant for extended periods before reactivating and infecting the bladder. This can lead to inflammation, the formation of granulomas and tuberculomas, and ultimately fibrosis and strictures, potentially causing urinary obstruction and renal failure.
Example 1: A patient presents with persistent urinary symptoms, including frequent urination, pain, and blood in the urine, unresponsive to standard antibiotic treatment. Further investigation reveals a history of pulmonary TB and imaging shows granulomas in the bladder, confirming bladder TB., A patient with a known history of latent TB develops symptoms of urinary tract infection, including dysuria and pyuria.Urine culture is negative for common bacteria, and further testing, including a CT scan and cystoscopy with biopsy, reveals bladder TB., A patient undergoing a routine health checkup reports occasional mild urinary discomfort.A tuberculin skin test is positive, and subsequent imaging reveals early signs of bladder TB, enabling prompt treatment and preventing progression to more severe disease.
Documentation should include details of the patient's presenting symptoms, medical history (including history of TB), results of laboratory tests (blood tests, urine cultures, AFB testing), imaging studies (intravenous urography, MRI, CT scan), and any procedures performed (cystoscopy, biopsy).Documentation of medical necessity for treatments and procedures is also essential.
