    Abstract:
    OBJECTIVES: The objectives of this study are to introduce the surgical technique of a modified spiral orthotopic ileal neobladder and to assess the long-term outcomes. PATIENTS AND METHODS: Between January 1998 and January 2006, 44 male and 7 female patients with bladder cancer received radical cystectomy (RC) and pelvic lymphadenectomy. An ileal segment 40 cm to 45 cm long was isolated to create a spiral orthotopic ileal neobladder, and the ureters were implanted into the reservoir using a non-refluxing split-cuff nipple technique. Preoperative, perioperative, and postoperative data were collected. Complications were classified as early (less than 3 months after surgery) or late (more than 3 months after surgery). Continence incidence and urodynamic studies were evaluated 5 years after surgery. Duration of follow-up was an average of 95 months (range 60-156 months). RESULTS: There were no perioperative deaths. The mean operative time was 315 ± 34 minutes. The mean blood loss was 783 ± 316 ml. There were 31 early complications in 21 patients (41%) and 42 late complications in 30 patients (59%). Urodynamic studies showed the maximum neobladder capacity to be 500 ± 71 ml, maximum flow rate to be 16 ± 5 ml/s and post-voiding residual (PVR) to be 50 ± 44 ml. Postoperative continence was excellent with a daytime continence rate of 90% and a nocturnal continence rate of 78% 5 years after surgery. CONCLUSIONS: The modified spiral neobladder is easy to perform and allows for excellent long-term results with regard to complications and continence.
