Objective: To examine the efficacy of robot-assisted laparoscopic modified ventral onlay lingual mucosal graft for complex ureteral stricture. Methods: The clinical data of 8 patients with ureteral stricture admitted to the Department of Urology, General Hospital of Southern Theater Command from May to October 2022 were retrospectively analyzed. There were 6 males and 2 females, aged (45.1±10.2) years (range: 34 to 64 years), body mass index (24.6±2.0) kg/m2 (range: 20.7 to 26.6 kg/m2). Five cases on the left side, 3 cases on the right side, the length of the ureteral structure was (3.1±0.7) cm (range: 2.2 to 4.5 cm). The value of preoperative serum creatinine was (113.8±22.3) µmol/L (range: 96 to 15 µmol/L). Before excising the structure segment, the titched anastomosed part of the dorsal wall of the ureter, and then the posteriorly augmented anastomotic, the remaining ventral side was augmented with a onlay lingual mucosa graft, then the omentum flap was used to wrap the reconstructed ureteral segment. The lingual mucosa graft with a length of 2.5 to 5.0 cm and a width of 1.0 to 1.5 cm was cut according to the actual structure. The surgery information of the patient, complications, and recent follow-up were recorded. Results: The operation under robot-assisted laparoscopy was performed successfully in the 8 patients without conversion to open surgery. The duration of the operation was (226.9±22.8) minutes (range: 210 to 255 minutes), estimated blood loss was (93.8±25.9) ml (range: 75 to 150 ml), the retention time of the postoperative drainage tube was (4.8±1.3) days (range: 3 to 7 days), and the duration of postoperative hospitalization was (11.1±3.6) days (range: 9 to 14 days). One week after the operation, the patient could pronounce correctly, enunciate clearly, and eat normally. Double J tubes were removed 4 to 8 weeks after the operation. The follow-up time in this group was 3 to 9 months, the follow-up patients underwent imaging and other examinations, which showed a significant improvement in hydronephrosis on the affected side, and the value of renal pelvic separation on the affected side was (1.4±0.8) cm (range: 0 to 2.3 cm). The serum creatinine value was (100.1±24.9) µmol/L (range: 76 to 155 µmol/L). Three months after the operation, the ureteroscopy showed that the ureter was smooth and the mucosa was normal. Conclusions: Robot-assisted laparoscopic ureteroplasty with a lingual mucosal graft is a safe and feasible operation for complex ureteral stricture without serious complications, which provides a surgical option for repairing ureteral stricture.
