OBJECTIVE: To investigate the safety and effectiveness of modified radical orchiectomy for stage I seminoma. METHODS: The clinical data of 28 patients with stage I testicular seminoma admitted to our hospital from January 2009 to August 2012 were retrospectively analyzed. 13 patients underwent modified radical orchiectomy and 15 patients underwent conventional transinguinal radical orchiectomy. The age, operation time, incision length, postoperative pain score, average postoperative hospital stay, complication rate, and postoperative recurrence rate of patients in the two groups were compared. RESULTS: The surgery was successful in both the modified radical group and the traditional radical group, and there was no significant difference between the two surgical approaches in terms of operative time, complication rate and postoperative recurrence rate (P > 0.05), but there was a significant difference in postoperative pain score, incision length and average postoperative hospital stay between the two groups (P < 0.05), and the modified radical group had a more aesthetic effect because the incision was smaller than the traditional radical group. . CONCLUSION: Modified radical orchiectomy for stage I seminoma is safe and effective, with minimally invasive and aesthetic incision, mild postoperative pain, and rapid recovery compared with transinguinal radical orchiectomy.
