A systematic review and meta-analysis of circumcision with Shang Ring vs conventional circumcision

Herein, we conduct a systematic review and meta-analysis of the current evidence to compare the safety and efficacy of Shang Ring circumcision (SRC) with conventional circumcision (CC) for male patients. Articles were searched by 2 independent reviewers. Overall, 8 randomized controlled trials involving 3314 patients were included. Compared with the CC group, SRC is associated with shorter operative time, lower intraoperative pain score, higher satisfaction with penile appearances, less intraoperative blood loss, lower adverse event rate, and lower wound bleeding rate. SRC appears to be a safer and more effective choice in comparison with CC for male patients.
