About

This is a prospect, randomized control trial to evaluate merits between flip and no flip technique in Shang Ring children circumcision.

Full description

The boys between 7 and 12 years old seeking for circumcision in The Affiliated Hospital of Medicine School of Ningbo University will be evaluated. Those who match the inclusion criteria and without exclusion criteria will be recruited.

The investigators will perform randomization preoperatively. participants were distributed into No Flip Group and Flip Group correspondingly according to a table of random number.

All of the procedures will be performed by a specific study surgeon in the hospital operation room. An assistant will take the pictures and recorder the parameters needed. In both groups, participants will be measured twice by a scale plate of holes, the diameter of penis with the foreskin noneverted and the diameter of exposed glans. Local anesthesia will be administered to the dorsal penile nerve using 2% lidocaine. The operation will not begin until the anesthesia is satisfied. The proper ring will be chosen according to different strategies of two groups. Participants will stay in hospital for 24 hours after operation. Pain during operation, half a hour post-operation and 24 hours will be evaluated, adverse events at hospital will be recorded carefully as well.

Participants will be advised to return usually at 7th, 14th, 21st, 28th and 90th post-operative days. However, if the wound does not heal completely 28 days post-operatively, the participant will be asked come to visit weekly until complete healing.
