Total bladder and posterior urethral reconstruction: salvage technique for defunctionalized bladder with recalcitrant posterior urethral stenosis.

PURPOSE: Recalcitrant posterior urethral stenosis is a challenging disease. When combined with a defunctionalized bladder, cutaneous urinary diversion is the most common surgical option. We present a novel technique of total lower urinary tract reconstruction, combining salvage cystectomy, ileal neobladder formation and urethral pull-through, as an orthotopic alternative in patients with a defunctionalized bladder and recalcitrant posterior urethral stenosis.

MATERIALS AND

METHODS

We completed a retrospective review of 8 patients who underwent salvage cystectomy, orthotopic ileal neobladder formation and urethral pull-through. Artificial urinary sphincter placement was performed in a staged fashion. Six patients received prostate cancer treatment including radiation therapy, 1 had urethral disruption after robotic radical prostatectomy, and 1 experienced bladder rupture and urethral distraction injury during a motorcycle accident. Patient demographics, operative variables and postoperative outcomes were examined.

RESULTS

No high grade complications were observed after salvage cystectomy, orthotopic neobladder formation and urethral pull-through. After staged artificial urinary sphincter placement, a median of 2 revision surgeries (range 0 to 4) was required to establish social continence. All patients maintained functional urinary storage, urethral patency and social continence at a median followup of 58 months. No patient had complications related to orthotopic neobladder formation, including ureteroileal anastomotic stricture or pyelonephritis, and no patient required cutaneous diversion.

CONCLUSIONS

Total lower urinary tract reconstruction with cystectomy, ileal neobladder formation and urethral pull-through offers an orthotopic alternative for patients with recalcitrant posterior urethral stenosis and defunctionalized bladders. Although it requires staged placement of an artificial urinary sphincter, this approach can offer functional urinary storage, durable urethral patency and avoidance of cutaneous urinary diversion.
