Abstract
Objective:To evaluate the clinical application value of 4K laparoscopy in precise varicocelectomy.Methods:A retrospective analysis was conducted on clinical data of 103 patients who underwent laparoscopic varicocelectomy between Jan.2020 and Jun.2024.Among them,50 patients(56 sides)were assigned to the 4K group,and 53 patients(60 sides)were assigned to the conven-tional high-definition(HD)group.In the 4K group,the deep red internal spermatic arteries,dark blue internal spermatic veins,and transparent lymphatic vessels were clearly identified under 2.0×magnification.All veins were dissected,ligated,and transected,while all arteries were preserved.In the conventional HD group,attempts were made to identify and preserve all internal spermatic arteries,the remaining spermatic vessels were then ligated and transected.If the internal spermatic artery could not be clearly identified or if it was injured,mass ligation and transection of the spermatic cord vessels was performed.Results:The internal spermatic artery identification rate was significantly higher in the 4K group than in the conventional HD group[100%(56/56)vs.51.7%(31/60),P<0.001].The 4K group also had a shorter operative time[(24.9±6.6)min vs.(30.5±8.3)min,P<0.001]and a lower incidence of hydrocele[0 vs.11.3%(6/53),P=0.027].Patients were followed up for 6 months postoperatively,no cases of epididymitis or testicular atro-phy occurred in either group.The 4K group showed a higher rate of semen quality improvement[68.0%(34/50)vs.47.2%(25/53),P=0.033].There were no significant differences in the incidence of scrotal edema or recurrence between the two groups(P>0.05).Conclusions:Compared with conventional HD laparoscopy,4K laparoscopy enables superior identification and preservation of the internal spermatic artery and lymphatic vessels,thereby facilitating precise varicocelectomy and yielding better clinical outcomes.关键词
