RESUMO
<p><b>OBJECTIVE</b>To observe the clinical effects of using the Chinese Shang Ring in circumcision children with either phimosis or redundant prepuce, and to investigate its superiority over the similar devices available.</p><p><b>METHODS</b>A total of 824 children with phimosis or redundant prepuce underwent circumcision with the Shang Ring. The clinical data were assessed concerning the duration of the procedure, incidence of post-operative complications, time of recovery and appearance of the penis.</p><p><b>RESULTS</b>The procedure duration was (2.6 +/-1.2) min, and the complications included infection in 4 (0.6%), edema in 21 (3.2%), delayed removal of the ring in 10 (1.5%), redundant and asymmetric mucosa attributable to performance in 6 (0.9%) of the cases. The wounds healed and the rings were removed at 13.4 +/- 5.8 days after circumcision, with well-smoothed incision and good cosmetic results.</p><p><b>CONCLUSION</b>Child circumcision with the Chinese Shang Ring is easy and simple in performance, with less operative time, fewer complications and better cosmetic results.</p>
