Mucosal fold as a mechanical cause of obstruction in orthotopic ileal neobladder

Studer's ortothopic neobladder after radical cistectomy has become a good alternative and has improved the patiens' quality of life. Voiding dysfunction after surgery is one of the possible late complications with incomplete emptying of the neobladder and chronical urinary retention. The mechanical obstruction may be due to recurrence of the tumor, anterior vaginal wall prolapse, urethrointestinal anastomosis stricture, mucose plug, stone and mucosal fold. We present a clinical case of voiding dysfunction after radical cystectomy with Studer's neobladder. One year after surgery the patient developed obstructive symptoms due to a mucosal fold of the neobladder. An endoscopic incision resolved the obstructive symptoms.
