Objective To evaluate the long term outcome of the continent urinary reservoir constructed with ileocecum appendix. Methods From 1985 to 1992,continent urinary reservoir was constructed by using ileocecum appendix after radical cystectomy for 56 patients,of which 11 have been followed up for over ten years. Results The daytime continence rate was 90% and the night continence rate 80%.The average capacity of the urinary pouch has been 388 ml,and the mean pressure 28 cm H 2O.The average urine flow rate is 9.6 ml/s.No evidence of ureteral reflux and no hyperchloremic acidosis have been observed.Stone formation in the pouch occurred in 1 patient,pseudo valve in the posterior urethra in 2 and stricture of the posterior urethra in 1. Conclusions Continent ileocecum appendix pouch might be considered as an ideal form of urinary diversion,characterized by low pressure,large capacity,continent and in situ urination.

Objective To study the clinical effects of intra internal iliac arterial chemotherapy for invasive bladder cancer after operation. Methods From February 1997 to June 2000,32 cases of invasive bladder cancer underwent partial cystectomy and arterial infusion pump implanted into the intra internal iliac artery, for postoperative chemotherapy. Results The patients have been followed up for 5～42 months, with a mean of 26 months,27 of the 32 patients have been free from the tumor,metastasis to lung and liver was noted in 2.Recurrence occurred in 3?10?16?30 months after operation respectively.Few side effects were noted. Conclusions Intra arterial chemotherapy might serve as an adjuvant therapy for invasive bladder cancer after operation.
