Purpose: When the appendix is unavailable, there are limited reliable methods for continent urinary diversion. After successful application of double-T pouch urinary diversion in adults we modified the technique for bladder augmentation and continent diversion.
Materials and methods: A 10-year-old male underwent bladder augmentation and continent urinary diversion with a hemi-T augment. Modifications of the T pouch technique are described in detail. We also reviewed the literature on tapered ileal diversions, such as the Yang-Monti procedure.
Results: One year after surgery the patient was continent. He was free of infection and bilateral hydronephrosis resolved. Urodynamics demonstrated a continent 350 ml reservoir without reflux.
Conclusions: For patients who require concomitant bladder augmentation and continent diversion a hemi-T augment is a suitable option when the appendix is unavailable. It is especially true when there is minimal bladder available for implantation of a Yang-Monti conduit.
