Prolapse of a simple ureterocele presenting as a vulval mass in a woman

Abstract  A 48‐year‐old woman presented with a large vulval mass after prolapse of a ureterocele. Her past excretory urogram showed a filling defect (cobra head appearance) in the bladder related to a single‐system ureterocele on the left. The mass was manually reduced back through to the urethra under sedation and a urethral catheter was inserted. The anterior wall of the ureterocele was resected transurethrally for definitive treatment.
