Hutch bladder diverticulum - unusual cause of adult obstructive uropathy.

OBJECTIVE: To present a case of a Hutch bladder diverticulum containing the ureteral opening. MATERIAL AND METHODS: An 83-year-old man presented a giant bladder diverticulum causing obstructive azotemia due to bilateral ureteral compression. Endoscopy revealed an unusual and potentially harmful anatomical alteration: the left ureteral orifice was inside in the diverticulum. Despite bladder emptying, the diverticulum remained full, causing bilateral ureteral compression. The patient underwent diverticulectomy with ureteroneocystostomy. RESULT: Post-operative follow-up showed renal and voiding functions restoration. CONCLUSION: Although clinical watching is a valid option in patients with Hutch diverticulum, reconstructive surgical approach, especially when complications are present, should be the standard of care.
