Microsurgical bypass for varicocele with nutcracker syndrome / 中华男科学杂志

ABSTRACT

Objective@#To investigate the clinical effect and feasibility of internal spermatic vein-inferior epigastric vein (ISV-IEV) bypass surgery in the treatment of varicocele complicated by left renal vein nutcracker syndrome (NCS).@*METHODS@#We retrospectively analyzed the clinical data about 30 cases of varicocele with left renal vein NCS treated by ISV-IEV bypass surgery in our hospital from June 2014 to February 2017. We reviewed the follow-up data and results of ultrasonography, routine urianlysis and semen routine examination.@*RESULTS@#All the operations were successfully accomplished and postoperative color Doppler ultrasonography showed that varicocele was cured in all the cases. At 6 months after surgery, sperm concentration and the percentage of grade a+b sperm were significantly improved (［34.47 ± 8.60］ ×10⁶/ml and ［63.54% ± 9.58］ %) as compared with the baseline (［19.90 ± 8.97］ ×10⁶/ml and ［37.93 ± 8.73］ %) (P <0.05). Hematuria was cured in 23 and alleviated in 1 of the 24 cases. Proteinuria disappeared in all the 14 cases, with neither scrotal pain symptoms nor obvious complications.@*CONCLUSIONS@#ISV-IEV bypass surgery, with its advantages of safety, effectiveness, minimal invasiveness, and simple operation, deserves wide clinical application in the treatment of varicocele with left renal vein NCS.
