Abstract:
Objective To investigate the safety and validity of laparoscopic autologous lingual mucosal graft ureteroplasty for the treatment of complex ureteral stricture.Methods A total of 10 patients who underwent laparoscopic autologous lingual mucosal graft ureteroplasty in our hospital from May 2021 to October 2023 were retrospectively analyzed.During the operation,the narrow segment was longitudinally dissected,and according to the length of stricture,the lingual mucosal graft of 2.0-7.0 cm in length and 1.0-1.5 cm in width was harvested and precisely anastomosed with the stenosed ureter,followed by double J stent placement.Results All the operations were successfully completed with no conversion to open surgery or intraoperative complications.The operative duration was(237.0±67.1)min,the estimated blood loss was 25.0(20.0,30.0)ml,the duration of drainage tube indwelling was 4.0(4.0,4.8)d,the duration of urinary catheter indwelling was 6.5(6.0,9.5)d,and the duration of postoperative hospitalization was 6.0(6.0,6.8)d.All the patients'oral function recovered well within 1 week,and the double J stent was removed 1-2 months after the surgery.The mean follow-up time was(12.3±7.1)months.One case of aggravated hydronephrosis on the affected side underwent a second laparoscopic ureteral stricture resection and end-to-end anastomosis.The remaining 9 cases showed significant improvement in hydronephrosis on the affected side,with improved renal pelvis separation[(2.9±1.2)cm,t=8.022,P=0.000]and renal function compared to before surgery.Their blood creatinine was(74.3±25.5)μmol/L,with no significant difference compared to preoperation[(80.1±26.6)μmol/L,t=1.825,P=0.105].Conclusion Laparoscopic autologous lingual mucosal graft ureteroplasty for the treatment of complex ureteral stricture is a safe and feasible ureteral reconstruction technique with advantages of quick recovery and reliable outcomes.
