Abstract：Objective: To compare the effects of single-incision laparoscope and conventional laparoscope in the treatment of varicocele based on randomized controlled trials.Methods: By searching PubMed, Embase, Cochrone liberary, the Chinese biomedical literature database (CBM) and China National Knowledge Infrastructure (CNKI), all of the eligible articles which conformed to the inclusion and exclusion criteria were harvested, and the risk of bias was evaluated according the Cochrone's methods.The observation indexes (operating time, bleeding, pain scores, length of hospital stay, hospital costs, sperm counts, sperm motility, sperm morphology) were analyzed using the software of RevMan 5.2.Results: A total of 12 articles (325 cases of single-incision group and 326 cases of conventional group) were analyzed in our study.The operating time (SMD: 0.70 [0.05, 1.34]) in single-incision group was significantly longer than in conventional group. The bleeding (SMD:-0.26 [-0.49,-0.03]) and the pain scores (SMD:-1.15 [-2.10,-0.20]) in single-incision group were significantly lower than in conventional group.However, there were no significant differences in the length of hospital stay (SMD:-0.37 [-0.76, 0.03]), the hospital costs (SMD: 0.02[-0.64, 0.68]), the sperm counts (SMD:-0.24 [-0.49, 0.01]), the sperm motility (SMD: 0.06 [-0.94, 1.05]), and the sperm morphology (SMD: 0.48 [-0.08, 1.03]) between single-incision group and conventional group.Conclusions: As compared with conventional laparoscope, single-incision laparoscope is a safe and effective minimally invasive surgical alternative for varicocele.
