Summary

Undiversion surgery in children with prior urinary diversion can be successful. Careful patient selection and surgical technique are crucial, especially for those with neuropathic bladders, to preserve renal function.

Area of Science:

  • Pediatric Urology
  • Surgical Reconstruction
  • Renal Function Preservation

Background:

  • Urinary diversion in childhood is performed for various lower urinary tract dysfunctions.
  • Long-term outcomes and the potential for reversal (undiversion) require evaluation.
  • Neuropathic bladder conditions present unique challenges in managing urinary diversion and subsequent undiversion.

Purpose of the Study:

  • To assess the outcomes of urinary undiversion in a cohort of patients previously treated with urinary diversion in childhood.
  • To identify factors influencing the success of undiversion and the preservation of renal function.
  • To compare outcomes across different bladder types: neurologically intact, neuropathic, and 'occult' neuropathic.

Main Methods:

  • Retrospective analysis of 18 patients undergoing urinary undiversion.
  • Categorization into neurologically intact, neuropathic, and 'occult' neuropathic bladder groups.
  • Surgical techniques included ureteroureterostomy and, for neuropathic bladders, bladder remnant excision with detubularised bowel substitution.

Main Results:

  • The simplest ureteroureterostomy was preferred for neurologically intact bladders.
  • Neuropathic bladders required more complex reconstruction involving bowel substitution.
  • Four patients had pre-operative deteriorating renal function; two ultimately required renal transplants, one complicated by anastomotic stenosis and infection post-surgery.

Conclusions:

  • Urinary undiversion is feasible in children with prior urinary diversion.
  • Management of neuropathic bladders necessitates tailored surgical approaches to mitigate risks.
  • Vigilant monitoring of renal function is essential, particularly in patients with pre-existing renal compromise or post-operative complications.
