Adult Ureterocele Presenting with Ureteral Obstruction and Urosepsis during Pregnancy.

INTRODUCTION Ureteroceles are cystic dilatations of the distal ureter that occur due to congenital ureteric wall weakness. They can be orthotopic, occurring in normal ureteric locations and most commonly seen in adults. On the other hand, heterotopic ureteroceles are located in ectopic ureters or in ectopic duplex renal systems, and are more common in children. Ureterocele causing obstruction in adults is less commonly reported. There are few case reports and small case series in the adult population that describe ureteral obstruction from ureteroceles, and only one published report of a ureterocele presenting as prolapsed mass containing stones during pregnancy. We describe a report of an adult presenting with an obstructing ureterocele and urosepsis during pregnancy. The ureterocele was successfully extirpated cystoscopically without radiation exposure to mother or fetus. We also review the varied presentations and management of obstructing ureteroceles in adults who have presented at our institution.
