Second 'pop-off' of fetal giant urinoma: case report and review.

ABSTRACT:

Background

Renal fornices rupture with urinoma formation in fetuses is an unusual condition that acts as a 'pop off' mechanism to buffer renal pelvis pressure. Ureteropelvic junction obstruction (UPJO) is the most common cause of prenatal hydronephrosis, but it rarely leads to the formation of urinoma. Fetal urinoma could be indicative of poor renal function after birth. We report a rare case of UPJO-related urinoma accompanied with urinary ascites, which ruptured during vaginal delivery.

Case presentation

A 30-year-old woman was admitted to our hospital at 25⁺³ weeks gestation for fetal bilateral hydronephrosis. This probable case of UPJO became further complicated at 29⁺⁵ weeks with the presence of a urinoma around the left kidney and ascites. Afterwa
