The prepuce operation in Sheung Wan usually takes about half a month to remove the ring, depending on the wound healing. The surgical recovery of the foreskin on the upper ring will be slower than that of circumcision, because it will take a few days for the redundant foreskin to be stuck by the ring.
Suggestion:
Pay special attention to erection during prepuce surgery, because there is nothing fixed on its wound. If the erection is too strong, it is easy to cause poor wound healing. I have had many secondary operations in Sheung Wan, so you should pay special attention.
