Calyceal rupture and perirenal urinoma as a presenting sign of recurrent ovarian cancer.

BACKGROUND

Rupture of the urinary collecting system with peripelvic extravasation of urine is an uncommon pathologic condition usually associated with ureteral obstruction from calculi.

CASE: We report a patient with calyceal rupture and peripelvic extravasation of urine secondary to distal ureteral obstruction by recurrent ovarian carcinoma. Diagnosis was established with computed tomography and renal scans. Placement of an indwelling ureteral stent via a nephrostomy resolved the urinoma.

CONCLUSION

Gynecologic oncologists should be aware that calyceal rupture is a potential complication of gynecologic malignancy. Causes of perirenal urinary extravasation and approaches to diagnosis and management are reviewed.
