Background: To compare the clinical effect of varicocelectomy treatment between patients who were diagnosed as secondary varicocele caused by nutcracker syndrome (NCS) and primary varicocele patients.
Methods: The secondary varicocele patients combined with NCS admitted in our hospital were systematically reviewed. All these patients had no obvious related symptoms such as gross hematuria and abdominal pain and so on. After the comprehensive examinations, the patients underwent the operation of microsurgical varicocelectomy. During the same period, the patients who were diagnosed as primary varicocele and underwent varicocelectomy were randomly selected as control group. The patients were required to make follow up 6 months and 1 year after the surgery in clinic. The number of varicocele recurrence of the both groups was calculated. And the patients’ numbers of improved semen quality, spouse pregnancy, testicular and perineal discomfort improvements were analyzed to compare whether there was significant difference between the two groups by Chi-square test.
Results: In left varicocele patients combined with NCS, one year after left varicocelectomy, the recurrence rate was elevated, patients’ symptom of scrotal pain did not alleviate obviously, and the rate of the spouse pregnancy declined.
Conclusions: For the patients with secondary varicocele caused by NCS, compared with the primary varicocele patients, the surgical treatment efficacy declined, and its higher recurrence rate might be related with the velocity of the stenosis site in left renal vein.
