"Purpose: Pain is one of the indications to treat varococele at any age. The purpose of this study is to find the significance of pyospermia in the patients surgically treated for scrotal pain associated with varicocele. Material and Methods: From January 2002 to December 2008, a total of 365 men underwent varicocelectomy. As the preoperative semen analysis, we classified patients of scrotal pain into two groups as pyospermia group I (N=136) and non-pyospermia group II (N=112). Preoperative and postoperative clinical symptoms were analyzed. The result was classified into completely resolved, partially resolved and unchanged based on the relief of pain. Results: Of 365 men, 248 (67.95%) patients were available for follow-up 3 months postoperatively. Among 119 patients with scrotal pain who have received the varicocelectomy, 42 (65.63%) and 5 (7.8%) patients in group I (64 patients) reported completely resolved and partially resolved respectively (mean response rate 73.44%). In group II (55 patients), 42 (76.36%) and 8 (14.55%) reported completely and partially resolved respectively (mean response rate 90.90%) (p<0.05). Seventeen and 5 patients in group I and II reported persistent pain, respectively. Conclusions: Patients with pyospermia surgically treated for scrotal pain associated with varicocele have tendency to have persistent pain after surgical treatment. This result may help the varicocele patients with persistent pain after receiving the surgery."
