A neosphincter for continent urinary catheterizable channels made from rectus abdominal muscle (Yachia principle): preliminary clinical experience in children.

Purpose: We investigated continence outcomes for patients undergoing primary or redo reconstruction of a urinary catheterizable reservoir involving the Yachia technique of intersecting two rectus abdominis strips over the outlet channel.

Materials And Methods: A retrospective evaluation of 22 consecutive patients operated from March 2009 to August 2010 was performed, consisting of 16 primary reconstructions (Macedo catheterizable ileal reservoirs) and 6 rescue cases for leaking stomas. Our data comprised 18 spina bifida patients, 1 sacral agenesis, 1 posterior urethral valves and 1 genitourinary tuberculosis. Mean age at surgery was 8.5 years (3-21 years). We evaluated continence at 3, 6, 12 months, and at the last follow-up based on data from urinary charts.

Results: Mean follow-up was 21.1 months (12-29 months). Overall continence was 100% for the primary cases and 66% for the redos (2/6 failed). Three patients had initial difficulty in performing clean intermittent catheterization but this resolved with time and experience.

Conclusion: Using Yachia's technique has improved the continence rate of our catheterizable reservoirs and was partially successful for suprafascial revision of incontinent conduits.
