title: How to choose appropriate ring size for Shang Ring male circumcision.
abstract: We investigated effects of ring size choosing strategy for Shang Ring male circumcision. Seventy-four cases were recruited and assigned into the larger or smaller ring group. Compared with the larger ring group, there was shorter operation time (7.5 ± 1.9 vs. 6.7 ± 1.4 minutes, P = 0.035) and less blood loss (1.6 ± 0.7 vs. 1.1 ± 0.8 mL, P = 0.014) in the smaller ring group. The smaller ring group also exhibited shorter healing duration than the larger ring group (22.3 ± 4.1 days vs. 24.4 ± 4.5 days, P = 0.041). When the measured size does not fit into commercially available size, it is better to choose the smaller one.
