Abstract: Objective To evaluate the urodynamic and functional characteristics of 26 patients who had underwent orthotopic contient globular ileal neobladder. Methods The clinical date of 26patients who underwent radical cystectomy were reviewed. The neobladder pressure, capacity, urethral pressure and urinary flow rate were collected at 3-12 months after operation. Results The neobladders average pressure was less than 15 cm H2O when the volume was 400 ml. The pressure was 22.4 cm H2O at 100% capacity. The mean pressure of contractions was less than 40 cm H2O. The mean filling pressure after operation was relative stable while the difference between 3 months and 6 months was statistically significant. The difference between 6 and 9 and 12 month showed no statistical significance. The mean post-void residual was 42 ml. A mean voiding flow rate of 19. 6 ml/s could be obtained by Valsalva. Conclusion The neobladder not only could offer adequate capacity at low pressures but also could give a satisfied continent.
