Application of the Yang-Monti channel in adult continent cutaneous urinary diversion.

Objectives To report 8 cases using the Yang-Monti channel with ileum for adult continent cutaneous urinary diversion. Methods From 2004 to 2006, 108 patients underwent urinary diversion, 8 of whom had a continent cutaneous reservoir using the Yang-Monti principle. Channels were created by transversely retubularizing 2 to 3 cm of ileum. Indications, technique, complications, and outcomes, such as continence and ease of channel catheterization, are reported. Results Five patients underwent a right colon reservoir urinary reconstruction after extirpative surgery. Orthotopic neobladders were not performed, owing to anatomic or oncologic concerns. Two additional patients underwent an augmentation, with 1 undergoing an Indiana pouch revision. All urinary reservoirs but 1 were connected to the umbilicus. Two strictures occurred, which were treated with in-office dilation. Incontinence was identified in 2 patients and successfully treated with dextran microspheres injections. All patients were continent at final follow-up. Seven patients continue to perform intermittent catheterization, and 1 patient is managed with an indwelling catheter, owing to comorbidities. Conclusions The Yang-Monti channel using ileum is an alternative as a neo-appendicoumbilicostomy in construction of continent cutaneous urinary diversion. The channel is surgically versatile and can be used in the creation of a right colon pouch when the appendix is unavailable.
