To compare the effect of oral mucosal ureteroplasty and traditional stricture resection and anastomosis in the treatment of ureteral stricture.

The clinical data of 40 patients with ureteral stricture admitted to the Second Affiliated Hospital of Anhui Medical University from July 2019 to July 2022 were retrospectively analyzed. According to the surgical methods, 18 patients were divided into the observation group (laparoscopic oral mucosal ureteroplasty) and 22 patients in the control group (laparoscopic resection and anastomosis of ureteral stricture). Both groups were evaluated by imaging examination at 3 and 6 months after operation.

All operations were successfully completed without obvious complications. The surgical time [(198±40) min] and intraoperative bleeding volume [40.0(40.0, 50.0) ml] in the observation group were higher than those in the control group [(170±42) min and 20.0 (10.0, 50.0) ml] (P<0.05). The degree of hydronephrosis in both groups improved significantly after surgery. The separation of renal pelvis in the study group decreased 3 months and 6 months after surgery, which was better than that in the control group, the cure rate 66.67% and effective rate 94.44% of the observation group were higher than those of the control group (54.55% and 86.36%), but there were no significant difference between the two groups (P>0.05).

Both surgical methods have shown good results in treating cases with a narrow segment length of 1.0-2.5 cm. Oral mucosal ureteroplasty may be more suitable for long segment ureteral stenosis due to its low intraoperative anastomotic tension.
