Brief Summary
We prospectively compared outcomes of subinguinal varicocelectomy for 40 patients who received 2 ml intratunical space injection of methylene blue before spermatic vein ligation with 40 controls in whom no mapping technique was adopted in the period between January 2008 and Feb. 2010, in Mansoura university hospital ward 7.After surgery, the patients were assessed at 2 weeks,6 and 12 months for varicocele recurrence, hydrocele formation, atrophy, pain or other complications with mean follow up was 15+ 7months.
Detailed Description
Methods. We prospectively compared outcomes of subinguinal varicocelectomy for 40 patients who received 2 ml intratunical space injection of methylene blue before spermatic vein ligation with 40 controls in whom no mapping technique was adopted in the period between January 2008 and Feb. 2010, in Mansoura university hospital ward 7.After surgery, the patients were assessed at 2 weeks,6 and 12 months for varicocele recurrence, hydrocele formation, atrophy, pain or other complications with mean follow up was 15+ 7months. Results: There were no intraoperative complications in either group. There were no adverse reactions, scrotal haematomas or atrophy. In group 1, no patient had a hydrocele at 3 months after surgery. By contrast, in group 2 (surgery alone) there were four cases of secondary hydrocele (10%; P=0.025)); no testicular hypertrophy was observed following lymphatic sparing surgery , One patient in each group had varicocele recurrence. Pregnancy was reported in 30 patients (37.5%) during a follow up period, 17 of them (42.5%) were group(1),P >0.34. difference was not significantly different among the two groups
