We aimed to systematically review complications, and recurrence rate of varicocele treatment by comparing the surgical ligature versus sclero-embolization techniques in children, adolescents and adults. The secondary outcomes were the evaluation of semen parameters and spontaneous pregnancy rate in adults. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Continuous variables were pooled using the inverse variance of the mean difference (MD) with a fixed effect, and 95% confidence interval (CI). The incidences of complications were pooled using the Cochran-Mantel-Haenszel Method with the random effect model and reported as Odds Ratio (OR), and 95% CI. Statistical significance was set two-tail p-value < 0.05. Twenty studies were included. Incidence of postoperative hydrocele was significantly higher in the surgical ligation group (OR 3.06 95% CI 1.06-8.88, p = 0.04). Incidence of postoperative orchiepidydimitys was significantly higher in sclero-embolization group (OR 0.26 95% CI 0.08-0.85, p = 0.02). Presence of normal spermatozoa was significantly higher sclero-embolization group compared with the surgical ligature group (MD 2.54% 95% CI 0.43-4.65, p = 0.02). No difference was found in overall complications, wound infection, testis pain, surgical site hematoma, total sperm count, sperm motility, pregnancy and recurrence rate. This review confirms that current data does still not support the superiority of one type of treatment over other ones.
Dear Editor, the pandemic spread of Coronavirus 2 infection (SARS-CoV-2), determining the coronavirus disease 2019 (Covid-19), had devastating consequences globally with several waves affecting social and economic life. The use of masks, physical distancing, testing of exposed or symptomatic persons, contact tracing and isolation have helped limit the transmission where they have been rigorously applied; however, these actions have proved not sufficient to limit the virus spread [...].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
