[Use of bowel segments for ureter reconstruction]

Area of Science:

• Urology
• Gastroenterology
• Surgical Reconstruction

Context:

• Extensive ureter damage or midureter defects necessitate complex reconstructive techniques.
• Restoring urinary tract continuity while preserving long-term renal function is paramount.

Purpose:

• To evaluate the safety and efficacy of ureter reconstruction using bowel segments.
• To identify patient populations and conditions where this reconstructive approach is contraindicated or limited.

Summary:

• Ureter reconstruction with bowel segments is a validated, reliable last-resort solution for extensive ureter damage, demonstrating favorable outcomes and low complication rates.
• This technique is contraindicated in patients with short-bowel syndrome or Crohn's disease and has limited applicability in children or those with progressive renal deficiency.
• The use of retubularized bowel segments is proposed to prevent renal deterioration, with antirefluxive implantation being recommended for continent bowel reservoirs with cutaneous stomas.

Impact:

• Provides a viable option for complex ureter defects, potentially improving patient outcomes and renal preservation.
• Highlights critical contraindications and limitations, guiding clinical decision-making for patient selection.
• Informs surgical strategies regarding antirefluxive implantation based on bladder reconstruction type.
