Urinoma – A Rare Presentation of Carcinoma of the Bladder

Abstract

Urinoma as a presenting sign of carcinoma of the bladder, as occurred in this case, is rare. Aspiration of the cystic mass under sonography and chemistry of the fluid confirmed the diagnosis. The inferior extension of the urinoma on CT scan confirmed the gradual fading of Gerota’s fascia into the retroperitoneum. Abdominal mass in the form of a urinoma is an uncommon presentation and only a few documented cases are reported in the literature. This case illustrates that the Gerota’s fascia fades inferiorly into the retroperitoneum.

Incidental detection of perinephric urinary leak on bone scintigraphy in a patient with urinary bladder carcinoma

“…[ 1 ] Urinoma resulting from bladder malignancy is rare and usually associated with vesicoureteric junction involvement. [ 2 3 ] Although bone scan is not used for evaluation of urinary leak per se , the accumulation of radiotracer outside the urinary system can be detected with SPECT-CT. Although there are reports of urinary leak diagnosed from other tracers,[ 4 5 6 7 ] the diagnosis of unsuspected urinary leak from bone scan is rare.…”
