Abstract:
Objective To evaluate the clinical value of cystectomy with prostate capsule sparing in orthotopic bladder replacement for bladder cancer. Methods A total of 56 male patients (mean age,62 years) with bladder cancer were included.Of them 40 cases were of primary tumors and 16 were of recurrent ones.Pathology by cystoscopy and biopsy showed transitional cell carcinoma in 53 cases and squamous cell carcinoma in 3.According to the analysis of B ultrasound,CT,MRI and cystoscopy, they were clinically diagnosed as recurrent multiple superficial tumors (n=27) and invasive tumors (n=29).Radical cystectomy with prostate capsule sparing was performed on them.Detubularized ascending colon (20 cases) or ileal segment (36 cases) was used to form a neobladder,which was anastomosed with distal portion of prostate capsule. Results Mean operative time of ascending colonic neobladder and ileal neobladder was 5 h 50 min and 6 h 20 min,with blood loss of 580 ml and 540 ml,respectively.Pathology showed pT 1N 0 in 28 cases,pT 2N 0 in 25 and pT 3N + in 3.During the follow up of 4 to 102 months (mean,42 months) 3 patients of pT 3N + died of bladder cancer and 5 died of other diseases.The cancer specific 5 year survival was 94% in cases of T 1N 0,83% in T 2N 0.At 1 year follow up,17 out of 18 patients (94%) with ascending colonic neobladder and 30 out of 30 patients (100%) with ileal neobladder were fully continent during the day,and 46 (96%) voided 1 to 2 times at night and could stay dry.Of 31 patients with preoperative adequate sexual function, 23 (74%) maintained potency postoperatively. Conclusions Radical cystectomy with distal prostate capsule sparing and reconstruction with an orthotopic neobladder is a relatively safe and reliable surgical procedure.It can improve the continence and potency without compromising the principle of tumor control.
