Infertility & Sexual Dysfunction(구연) (E-193) 통증을 동반한 정계정맥류 환자에서 정계정맥류 수술의 효과에 대한 메타분석 부산대학교 의과대학 비뇨기과학교실 박지훈, 박남철, 박현준 Purpose: This study aimed to evaluate the difference in pain resolution rate based on factors that are related to varicocele characteristics and surgical methods. Materials and Methods: The literature search was conducted using PubMed (Medline) and EMBASE (1980~December 2018). Keywords used for the search were "varicocele", "varicocelectomy OR ligation OR repair" and "pain OR painful". Two authors reviewed the titles and abstracts of the related articles independently. Results: Fourteen studies were included in the analysis. There were no significant differences in the postoperative pain resolution rate with respect to varicocele grades I, II and III. The resolution rate was significantly higher for dull pain than for sharp pain (RR, 1.11; 95% CI, 1.02~1.22; p=0.02). There were no significant differences in postoperative pain resolution rate with respect to various surgical approaches. Microsurgical varicocelectomy showed a significantly higher pain resolution rate than laparoscopic varicocelectomy (RR, 0.77; 95% CI, 0.60~ 0.99; p=0.04). Conclusions: Patients with varicocele complaining of dull pain preoperatively had a higher resolution rate of postoperative pain than those complaining of sharp pain. We also found that microsurgical varicocelectomy showed better surgical outcome than laparoscopic varicocelectomy. However, there were no significant differences in pain resolution rate based on the varicocele grade and surgical approach. keywords : Pain, Varicocele, Varicocelectomy
