Abstract:
Objective To explore the safety and efficacy of laparoscopic left renal vein stent implantation combined with microsurgical varicocelectomy in the treatment of nutcracker syndrome complicated with varicocele.Methods A retrospective analysis was conducted on the data of 50 patients with nutcracker syndrome complicated with varicocele admitted to our hospital during Nov.2018 and Jul.2023.All patients underwent laparoscopic left renal vein stent implantation combined with microsurgical varicocelectomy.Results Altogether 47 patients were followed up after operation,with a mean age of(21.45±3.84)years.All operations were successful,and gross hematuria,proteinuria,abdominal pain and other symptoms relieved within 3-7 days after surgery.Postoperative follow-up showed that no patients had serious complications or recurrence of clinical symptoms.Left renal vein ultrasound and CT showed that the blood flow of the left renal vein was restored,and the stent position was stable.Compared with those before surgery,the angle between the abdominal aorta and the superior mesenteric artery[(44.91±6.59)° vs.(22.58±6.61)°]and the diameter of the left renal vein at the angle[(6.03±0.99)mm vs.(1.87±0.46)mm]were significantly increased,and the blood flow velocity of the left renal vein at the angle[(48.77±14.79)cm/s vs.(102.53±41.15)cm/s]was significantly decreased,with statistically significant differences(P＜0.001).Scrotal ultrasound confirmed that there was no recurrence of varicocele 6 months after surgery,and the diameter of the spermatic vein was significantly reduced,with statistically significant differences(P＜0.001).Semen analysis showed that the sperm concentration[(60.27±48.45)×106/mL vs.(36.57±36.67)×106/mL,P=0.032]and percentage of rapid forward movement of sperm were significantly increased[(22.54±10.70)vs.(15.01±10.77),P=0.005],with statistically significant differences.The increase value of semen concentration[(23.7±41.48)×106/mL vs.(6.12±4.97)×106/mL,P=0.016)]increased after combined operation compared with left renal venous stenting alone,and there was no significant difference in the diameter of spermatic vein,inner diameter of renal vein and flow rate between the two surgical methods(P＞0.05).Conclusion Laparoscopic left renal vein stent implantation combined with microsurgical varicocelectomy is a minimally invasive,safe and effective method for the treatment of nutcracker syndrome complicated with varicocele.
