title: A randomized clinical study of circumcision with a ring device versus conventional circumcision.
abstract: OBJECTIVE
  We investigated the safety and efficacy of Shang Ring™ male circumcision and conventional sleeve resection circumcision in a randomized study.
  
  
  METHODS
  During the same period, 479 cases of Shang Ring circumcision and 354 of sleeve resection circumcision were performed. Complete followup data were evaluated on the 2 groups. Operative time, pain score, blood loss, postoperative complications, wound healing time and treatment costs were compared.
  
  
  RESULTS
  There was no statistically significant difference in average age and foreskin status between the 2 groups preoperatively (p >0.05). Compared to the conventional group, there were shorter operative time, less blood loss and a lower intraoperative pain score in the ring group (p <0.05). In addition, ring male circumcision showed a lower complication rate than conventional circumcision (6.89% vs 13.28%, p = 0.002). However, wound healing time in the ring group was longer than in the conventional group (mean ± SD 19.86 ± 5.24 vs 13.42 ± 2.35 days, p <0.001).
  
  
  CONCLUSIONS
  Shang Ring male circumcision is a safe, efficient procedure with a relatively low complication rate and high patient satisfaction. It may be worthwhile to popularize this method, especially in countries where the general population has low to limited resources.
