Clinical efficacy of transumbilical single-port laparoscopy combined with ureteroscopy versus conventional laparoscopy in the treatment of upper and middle ureteral stenosis
Objective:To explore the feasibility and postoperative efficacy of transumbilical single port laparos-copy combined with ureteroscopy in the treatment of upper and middle ureteral stenosis.Methods:The case data of 35 patients admitted to our hospital from April 2020 to March 2022 for ureteral stenosis who underwent ureteral stenosis segment resection followed by reanastomosis were retrospectively analyzed.There were 25 patients in the single-port laparoscopy combined with ureteroscopy group and 10 patients in the conventional laparoscopy group.The operation was performed in a reclined lithotomy position,and the single-port laparoscopy group was operated with an umbilical incision of about 3 cm.A four-channel single-port puncture kit was used for placing the laparo-scopic observation holes and operation holes,and the ureteral stents were precisely localized according to the uret-eroscopy and left in place.Clinical data such as relevant surgical indexes,postoperative complications,and patient satisfaction were analyzed in comparison with the traditional laparoscopic group.Results:All patients were suc-cessfully completed the operation,and patients in the single-port laparoscopic group didn't experience intraopera-tive additional auxiliary holes or conversion to open surgery.The operation time of the single-port laparoscopic group was(125.41±42.07)min,and the length of postoperative hospitalization was(7.67±3.42)d.The differ-ences were not statistically significant when comparing with those of the traditional laparoscopic group.There were no obvious complications during the perioperative period in the two groups.After more than 1 year of follow-up period,the patients'hydronephrosis was reduced,and the renal function was improved.In addition,postopera-tive drainage tubes weren't indwelt in some of the patients in the single-port laparoscopic group,and the patients'surgical incisions were beautiful and satisfactory.Conclusion:Single-port laparoscopy combined with ureteroscopy is safe and feasible for the treatment of upper and middle ureteral stenosis and has the advantages of fast postoper-ative recovery and good cosmetic results.It is a clinical option for operators with some experience in laparoscopic techniques.
