Urinoma - Rare Manifestation of Carcinoma Bladder

Jahanvi Singh, Sushilkumar Kale

Abstract: A urinoma is a collection of urine outside the urinary tract as a result of disruption of the collecting system. Obstructive causes of urine extravasation secondary to carcinoma are not unseen but display a delayed diagnosis due to the gradual onset of symptoms. Urinoma as a presenting sign of carcinoma of bladder, as occurred in this case, is rare. We present the case of a 65 - years - old male patient who was admitted to hospital with lower abdominal pain, increased frequency of urination and haematuria. We describe his case from the initial clinical diagnosis of haematuria to the final diagnosis of an infected urinoma after a calyceal rupture from an obstructive uropathy in form of carcinoma bladder. This case highlights the importance of early computerized tomography imaging in patients as ultrasound scans can sometimes be misleading. Misdiagnosis of infected urinomas delays definitive treatment and leads to increased morbidity.
