Abstract：Objective To evaluate the curative effect of microsurgical varicocele ligation combined with left spermatic vein inferior vena cava shunt in the treatment of secondary varicocele in nutcracker syndrome(NCS).Methods A total of 16 patients with secondary varicocele of NCS who visited the Department of Andrology at the First Affiliated Hospital of Zhengzhou University from July 2020 to March 2023 were selected,and the clinical symptoms,Doppler ultrasound results,and other examination indicators before and after surgery were compared.Results All 16 patients underwent surgery successfully,with a surgical time of(104.69±40.80)minutes and an hospital stay of(4.69±0.49)days.Postoperative follow-up showed that the pain or swelling of the scrotum disappeared,and there were no postoperative complications such as incision infection,fat liquefaction,testicular.The renal vascular ultrasound before and after operation were compared,and it showed that the velocity(PV1)of left renal vein(LRV)at the angle between abdominal aorta and superior mesenteric artery(SMA)decreased(P＜0.01),while the velocity of LRV at the renal hilum(PV2)had no statistical significance(P＞0.05),PV1/PV2 decreased(P＜0.01).The internal diameter of the LRV at the hilum of the kidney had no statistical significance(P＞0.05),but the internal diameter of the LRV at the angle between the abdominal aorta and the SMA had increased(P＜0.05),and its ratio had decreased(P＜0.05).Conclusion Microsurgical varicocele ligation combined with left spermatic vein inferior vena cava shunt is a safe,effective,feasible and worth popularizing method for the treatment of secondary varicocele to NCS.
