Abstract:Objective To explore the safety, feasibility and effectiveness of (laparoscopy + ureteroscopy) combined endoscopic techniques in the treatment of iatrogenic ureteral stenosis.Methods A retrospective analysis of the clinical data of 15 patients with iatrogenic ureteral stenosis treated with (laparoscopic + ureteroscopy) combined endoscopic techniques from January 2018 to December 2020. 8 males and 7 females; age 31~65 years, average (38.50 ± 7.10) years old, preoperative hydronephrosis on the affected side: 4 cases of mild, 9 cases of moderate, 2 cases of severe; renal function: Creatinine (120.33 ± 16.52) μmol/L, Urea Nitrogen (13.22 ± 2.12) mmol/L. The length of the stenosis was 0.5 ~ 2.5 cm, with an average of (1.32 ± 0.30) cm; the stenosis: 3 cases in the upper part, 7 cases in the middle part, and 5 cases in the lower part.Results All the 15 patients underwent smooth end-to-end anastomosis (laparoscopic + ureteroscopy) combined with endoscopic resection of ureteral stricture. Operation completion time (190.64 ± 25.33) min, postoperative catheter removal time (14.50 ± 0.72) d, postoperative time to get out of bed (1.54 ± 0.32) d, postoperative bowel function recovery time (1.81 ± 0.54) d, the blood loss was (119.74 ± 48.22) mL, the postoperative discharge time was (7.22 ± 0.80) d (the double J tube was not removed), and the double J tube was removed (70.51 ± 8.11) d. After 7 ~ 19 (12.70 ± 5.34) months of follow-up, the symptoms of the diseased side disappeared, hydronephrosis and renal function improved, and no ureteral stenosis recurred.Conclusion (Laparoscopy + ureteroscopy) combined endoscopic technique in the treatment of iatrogenic ureteral stenosis is safe, feasible and effective; it can quickly and accurately locate the stenosis and completely remove the stenosis, which is an important supplement to the treatment of iatrogenic ureteral stenosis.
