Abstract:
Objective To evaluate the urodynamic parameters of W shape orthotopic ileal neobladder during a 36-month follow-up post-operatively.Methods Forty-five consecutive patients underwent radical cystectomy and W shape ileal neobladder substitution for muscle-invasive bladder cancer were recruited.Follow-up and urodynamic evaluation were performed at 12 and 36 months after surgery.Cystourethrography,ultrasonography,IVU and renal function test were performed during the follow-up.Results Of the 45 patients,3 were dead during the follow-up because of cancer-related causes.When comparing to the 12-and 36-month urodynamic parameters,Qmax,MCC,compliance,end-filling pressure,peak flow pressure and PVR respectively were 15.6 ± 2.3 ml/s and 14.9 ± 1.9 ml/s,588.0 ± 264.6 ml and 561.0 ±197.4 ml,27.6±8.4 ml/cm H2O and 29.5 ±1.7 ml/cm H2O,24.4 ±5.2 cm H2O and 33.0 ±6.8 cmH2O,60.7 ±18.0 cm H2O and 79.9 ±28.2 cm H2O,83.5±24.4 ml and 80.4 ±26.8 ml.At early and late evaluation,daytime continence rate was 90％ and 94％,night continence rate was 48％ and 74％.Conclusions Orthotopic W shape ileal neobladder was proven to maintain an adequate capacity and low pressure during a 36-month period of follow-up.The urodynamic results support this urinary diversion as a valid treatment option for muscle-invasive bladder cancer.
