This study presents a novel, simple technique for creating ileal bladders for bladder replacement, requiring only a short ileal segment. The method demonstrated excellent patient outcomes, including good bladder capacity and daytime continence.

Area of Science:

  • Urology
  • Surgical Innovation
  • Reconstructive Surgery

Background:

  • Bladder replacement is a complex procedure.
  • Existing techniques may require longer ileal segments or present challenges in anastomosis.
  • There is a need for simpler, effective bladder substitution methods.

Purpose of the Study:

  • To evaluate a novel technique for creating detubularized folded O-shaped ileal bladders.
  • To assess the efficacy and safety of this method for bladder replacement.
  • To determine the feasibility of using a short ileal segment (300-400 mm).

Main Methods:

  • Seven patients underwent bladder replacement using a submucosal needle tunneling technique for ureteral implantation.
  • A detubularized folded O-shaped ileal reservoir was created.

  • Anastomosis to the urethra was simplified by tailoring the ileum to reduce tension.

    • Main Results:

    • Follow-up ranged from 24 to 46 months.
    • Excellent upper tract function and good evacuation with minimal residual urine were observed.
    • Mean bladder capacity was 367 mL with low intra-ileobladder pressure.
    • Daytime continence was achieved in all patients; mild enuresis in three.
    • No reflux was detected on voiding cystourethrography.

    Conclusions:

    • The described ileal bladder technique is simple to create and yields reliable results.
    • A short ileal segment and mesentery are not significant limiting factors.
    • This method offers a promising option for bladder replacement surgery.
