輸尿管鏡球囊擴張術在良性輸尿管狹窄中的應用
[Abstract]:Objective to investigate the clinical effect of ureteroscopic balloon dilatation for benign ureteral stenosis (US). Methods the data of 18 patients with US treated by ureteroscopic balloon dilation were retrospectively analyzed. Male 8 cases, female 10 cases, the age is 21 73 years old, average 42 years old. There were 17 cases of stenosis and 1 case of atresia. The length of the narrow segment was 0.5 cm in 10 cases, 0.5 and 1.5 cm in 6 cases and above 1.5 cm in 2 cases. The stenosis was located in the junction of ureteropelvic junction in 3 cases, upper segment in 4 cases, middle segment in 4 cases and lower segment in 7 cases. Results all the 18 patients found the correct passage under ureteroscope and performed balloon dilatation. There were 10 cases with single 7F ureteral stents, 8 cases with double 5F ureteral stents, 17 cases with double J tubes for 6 ~ 12 months and 1 case with double J tubes for 3 months. Ten cases were followed up for 12 ~ 36 months. 6 cases were re-stenosis after extubation for half a year. After secondary balloon dilatation, 2 cases had long ureteral junction (UPJ), renal filtration function was less than 20 ml / min, and reexamined 1 year after operation. Stricture again, after retroperitoneal laparoscopic UPJ plastic surgery is effective. Conclusion Ureteroscopic balloon dilatation is a safe and effective method for the treatment of US. It can be used as the first choice of US in unilateral renal function with mild to moderate damage in length of less than 1.5 cm.
