vein in the spermatic cord fat was cannulated. A 7-9 cm segment of the spermatic cord was clamped for 8-10 min; at the start of the ischaemia time, 1.5-3 mL of 3% atoxysclerol was injected into the cannulated vein. After sclerotherapy, the vein was ligated at the injection site, and the blood flow to the cord was restored. RESULTSThe mean operative duration was 25 min. Follow-up at 3 and 6 months after surgery, with objective examination and scrotal ultrasonography, revealed one case of clinical recurrence/persistence. The most common complication was penile lymphangitis (nine men) that regressed spontaneously; three men had temporary orchialgia. There were no cases of secondary hydrocele or testicular atrophy. CONCLUSIONSThe modified technique appears to be relatively easy and safe, and to of low cost. Given the promising results in terms of complications and persistence, the treatment appears to be a suitable first-line approach for the surgical treatment of varicocele.
