Objective This study is aimed to evaluate the association between varicocele and other vascular diseases through a systematic reviews and meta-analyses. Material and methods We searched Cochrane Central Register of Controlled Trials, Embase, PubMed, and Web of Science for studies that reported varicocele and other vascular diseases published before 30 June 2021. The meta-analysis was performed by Revman V.5.2 to calculate the pooled odds ratios and corresponding 95% confidence intervals. Subsequently, the impact of publication bias was evaluated, and sensitivity analysis as performed to assess our results’ robustness. Results In total, seven case–control studies, including 803 varicocele cases and 727 controls, were included. Our meta-analysis results showed that the varicocele patients had a higher risk of saphenofemoral insufficiency when compared with the control group (odds ratio [OR]: 2.80; 95% confidence intervals [CIs]: 2.03, 3.84; p < 0.00001). Additionally, varicocele patients also had a higher risk of lower extremity venous insufficiency when compared with the control group (OR: 2.34; 95% CI: 1.58, 3.47; p < 0.0001). However, there was no statistical difference in hemorrhoid risk between both groups (OR: 1.13; 95% CI: 0.28, 4.59; p = 0.87). Conclusion Our study demonstrated that varicocele patients have higher risk of saphenofemoral and lower extremity venous insufficiencies but not the risk of hemorrhoids. |
