[Shang Ring scissor circumcision versus electrotome circumcision for redundant prepuce]

To compare the clinical effects of Shang Ring scissor circumcision (SC) and electrotome circumcision (EC) in the treatment of redundant prepuce or phimosis.Methods: Results: Conclusion.

This retrospective study included 524 patients with redundant prepuce or phimosis, 422 treated by SC and 120 by EC. We made comparisons between the two groups of patients in the operation time, intra- and post-operative pain scores, pain scores before, at and after ring removal, wound healing time, and incidence rates of postoperative edema and incision dehiscence.

The operation time was longer in the SC than in the EC group (［59.99±5.39］ vs ［39.94±4.94］ sec, P<0.05), but there were no significant differences between the two groups in the intraoperative pain scores (1.02±0.74 vs 1.08±0.59, P>0.05) or the pain scores within 24 h after operation (6.74±1.01 vs 6.56±1.06, P>0.05), 24 h prior to ring removal (1.14±0.69 vs 1.10±0.64, P>0.05), and after ring removal (2.73±0.74 vs 2.85±0.75, P>0.05) except at ring removal, which was remarkably lower in the SC than in the EC group (3.56±0.47 vs 4.77±0.58, P<0.05). The wound healing time was markedly shorter in the former than in the latter (［14.11±1.26］ vs ［39.78±7.55］ d, P<0.05), but the incidence rate of incision dehiscence showed no significant difference between the two groups (4.03% ［17/422］ vs 9.17% ［11/120］, P>0.05). The rate of postoperative satisfaction with the external penile appearance was 100% in both of the two groups.

Shang Ring scissor circumcision is preferred to electrotome circumcision for its advantages of less pain at ring removal and shorter healing time despite its longer operation time.
