An unusual consequence of an usual condition: Spontaneous psoas urinoma in a case of urinary tract obstruction

Abstract

Urinoma and urine leaks can occur at any level from the calyx to the urethra. An urinoma is an encapsulated collection of urine in any confined space or may present as ascites. Urinoma can occur due to multiple causes involving two broad categories-nonobstructive and obstructive. We present a rare case of urinoma in the iliopsoas compartment in a case of urinary tract obstruction due to ureteric calculus. Though, urinomas in various compartments including the iliopsoas are a relatively common occurrence due to iatrogenic trauma like pelvic, gynecological, retroperitoneal and gynecologic surgeries; obstructive causes including ureteric calculi are rare and even rarely reported. Timely recognition and treatment of this uncommon condition is important to avoid complications like abscess formation and electrolyte imbalances.
