Summary

This study shows that a modified sigmoid colon neobladder offers excellent urinary continence and capacity after radical cystectomy for bladder cancer. The procedure is surgically simple and provides satisfactory bladder replacement.

Area of Science:

  • Urology
  • Surgical Oncology

Background:

  • Radical cystectomy is a standard treatment for bladder cancer.
  • Orthotopic neobladder construction aims to restore urinary function after cystectomy.

Purpose of the Study:

  • To evaluate the efficacy and safety of a modified sigmoid colon neobladder technique.
  • To assess urodynamic parameters and continence rates following neobladder reconstruction.

Main Methods:

  • 24 patients underwent sigmoid colon neobladder construction after radical cystectomy.
  • Urodynamic testing was performed at 9 and 18 months post-surgery.
  • Surgical complications and functional outcomes were meticulously recorded.

Main Results:

  • High rates of daytime continence (95.2% at 9 months, 94.1% at 18 months).

  • Significant nocturnal incontinence rates (42.8% at 9 months, 29.4% at 18 months).
  • Mean neobladder capacity increased from 414 cc to 492 cc, with stable endoluminal pressure.

    • Conclusions:

    • The modified sigmoid colon neobladder is a surgically feasible procedure.
    • It provides satisfactory bladder replacement with good functional outcomes in select patients.
    • Long-term urodynamic stability and continence were demonstrated.
