Objective To explore the diagnosis and treatment for ureterovesical junction (UVJ) stricture. Methods 18 cases of UVJ stricture were analysed retrospectively,of them unilateral stricture of UVJ in 11(left 5,right 6),bilateral stricture of UVJ in 7.The ureterovesicoplasty was performed in 7 cases.The procedure of passive dilation of the UVJ and placing a double-J stent under endoscopy were performed in 6 cases.The plasticity of UVJ with the mucosa of bladder were performed in 7 cases. Results All cases were followed up 2 months to 23 years and cure rate was 78%,the rate of improvement was 22%.67% of cure rate was achieved by stent placing.The renal function, hydronephrosis were obviously improved after operation and there were no vesicoureteral reflux. Conclusions The passive dilation of the ureter and then placing a double-J stent under endoscopy is a safe and effective measure.The ureterovesicoplasty and the procedure which plasticity of UVJ with the mucosa of bladder are the safe and effective methods.

Background and purpose:Radical nephroureterectomy can be performed in a variety of ways, and each method has its advantages and disadvantages. It still remains controversial for choosing the surgical methods. In this study, we chose six surgical methods and investigated the safety and efficacy of different methods in treating upper urinary tract carcinoma.Methods:We retrospectively analyzed 135 patients with upper urinary tract transitional cell carcinoma who underwent operations in our hospital from Jan. 2002 to Oct. 2013, and compared the data of six different operations in-cluding operating time, volume of bleeding, time of bowel function recovery and incidence of bladder carcinomas.Results:The operations were successfully completed in groups A and B. Five cases in group C were transferred into group A be-cause of failing to pull the nub of the ureter. Two cases in group D were transferred into group A because of failing to pull the nub of the ureter. Three cases in group E were transferred into group D and 1 case was transferred into group A because of adhesion or bleeding. One case in group F was transferred into group A because of bleeding. There was no statistically significant difference in survival rates among six operations.Conclusion:Six operations are all safe and effective for the treatment of upper urinary tract carcinomas. Each method has its advantages and disadvantages. We should choose differ-ent methods according to particular cases.
