Ileal neobladder reconstruction after radical cystoprostatectomy

Area of Science:

• Urology
• Surgical Oncology

Background:

• Radical cystoprostatectomy for invasive bladder cancer necessitates bladder substitution.
• Patient acceptance and functional outcomes are key considerations for neobladder reconstruction.

Purpose of the Study:

• To evaluate the efficacy and patient acceptance of O-shaped ileal neobladder reconstruction.
• To assess the functional outcomes and complication rates of this specific neobladder technique.

Main Methods:

• O-shaped ileal neobladder reconstruction using a 40 cm ileal segment after radical cystoprostatectomy.
• Le Duc-Camey method for bilateral ureteral implantation.
• Urodynamic studies to assess reservoir capacity, pressure, and urethral closure pressure.

Main Results:

• All five patients achieved daytime urinary continence within six months.
• One patient experienced mild nocturnal incontinence, managed by timed voiding.
• Urodynamic studies revealed a high-capacity (mean 456 mL), low-pressure reservoir with minimal residual urine.
• Mean maximal flow rate was 22.2 mL/sec, and mean maximal urethral closing pressure was 74.4 cm H2O.
• No neovesicoureteral reflux was observed; transient hydronephrosis resolved in most cases.

Conclusions:

• O-shaped ileal neobladder reconstruction is a viable option for bladder substitution after radical cystoprostatectomy.
• The procedure demonstrates good functional outcomes, high continence rates, and patient acceptance.
• This technique offers a promising solution for patients requiring bladder replacement due to invasive bladder cancer.
