Abstract:
Objective To investigate the characteristics and mechanism of W-shaped orthotopic ileal neobladder. Methods A total of 20 patients with W-shaped orthotopic ileal neobladder after total cystectomy were evaluated by urodynamic examinations (questionnaire of urination,uroflowmetry,post-voiding(PVR) residual urine volume measurement,enterocystometry and resting urethral pressure profilometry);meanwhile cystourethrography,B-ultrasound,renal function test and IVU were performed. Results Of the 20 cases,2 suffered from daytime incontinence and 6,nocturnal incontinence.The maximum capacity of neobladder was (492.9?177.8)ml,and maximum pressure within the reservoir was (32.1?8.6 )cm H 2O (1 cm H 2O=0.098 kPa).The urine flow curve showed continual type in 12 cases and intermittent type in 8,with maximum uroflow rates of (14.9?2.5 )ml/s,(7.7?2.8)ml/s;capacity of neobladders of (409.0?96.1)ml,(622.1?197.7)ml;PVR of (9.2?11.8)ml,(69.0?38.4)ml,respectively,in the 2 type groups.These values were significantly different between the 2 groups (P
