Huge Perirenal Urinomas in a Woman during the Postpartum Period / 대한비뇨기과학회지

ABSTRACT

Urinary tract dilation is one of the most common side effects during pregnancy. This is primarily a physiologic phenomenon that is typically more prominent on the right side, and it is caused by hormonal changes and mechanical obstruction. Occasionally, urinary tract dilation leads to more serious urinary tract problems such as infection, obstructive renal failure and urinomas. Urinomas are also known as pararenal pseudocysts, and they generally occur as a result of urinary system disruption, but they only rarely occur with pregnancy. We report here on an unusual case of extremely large bilateral perirenal urinomas that were detected during the postpartum period. This was successfully resolved by percutaneous drainage and ureteral stents.
