RESUMO
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.
