The object of this study is to report the urodynamic data from 46 male patients who underwent orthotopic "N" neobladder replacement after radical cystectomy during a 12-month period and to provide urodynamic proof for the improvement of this technique.46 consecutive male patients underwent radical cystectomy and orthotopic "N" neobladder substitution because of muscle-invasive bladder cancer.Uroflowmetry,cystometry,and urethral pressure profilometry were analyzed at 3-12 months after surgery.The volumes of neobladders with a mean pressure of less than 15 cmH2O was less than 400 ml and 100% capacity with 22.4 cmH2O at 6 months.The mean pressure of contractions was less than 40 cmH2O at 6 months.The mean filling pressure after operation at 3 months was higher compared with that at 6 months.No difference was observed in other time point.When comparing the 9-and 12-month urodynamic characteristics,no significant changes were observed in cystometric capacity.The mean post-void residual is 58 ml.A mean voiding peak of 16.2 ml/s can be obtained by Valsalva.The daytime continence rate was 90% at 12 months while the nighttime continence rate was 60%.
