Endoscopic Creation of a Neochimneycystotomy: A Case Report of a Ureteroileal Chimney Stricture.

Background: There are many nonmalignant complications after urinary reconstruction. Anastomotic strictures and redundancy of an ileal chimney are such. A patient with both issues might necessitate an open surgical approach; yet endoscopic techniques are more attractive for these older frail patients. Case Presentation: A 61-year-old woman with a history of bladder cancer who underwent radical cystectomy and neobladder creation now develops left hydronephrosis and a redundant ileal chimney with severe metabolic acidosis. She underwent endoscopic creation of a neochimneycystotomy. Conclusion: The refinement of endoscopic techniques moves the field of surgery away from open surgery, which is beneficial for patients. This endoscopic technique treated the anastomotic stricture as well as redundant ileal chimney in a novel way that has not been reported previously in the literature.
