Meatoplasty / Meatotomy / Transmeatal Ureathroplasty

Meatoplasty / Meatotomy

A urethral stricture at the tip of the penis is called meatal stenosis. If the rest of the urethra is normal, then a very simple and very quick surgery with a fast recovery is a meatoplasty/meatotomy. In this surgery, we do not remove the scar tissue. Instead we “unzip” the urethra by cutting through the scar tissue and we keep cutting past the scar tissue for another 2 cm until we reach healthy urethra. We stitch that healthy urethra to the skin. This does not result in a new urethral opening; instead it results in a longer urethral opening, the tip of which still has scar in it but the inner end of it has healthy urethra.

Transmeatal urethroplasty

A transmeatal urethroplasty means that the entire surgery is done through the small urethral opening in the head of the penis. This is an alternative to the quicker and easier meatoplasty/meatotomy surgery. This surgery takes slightly longer (60-90 minutes) and requires taking a skin graft from the cheek. The benefit is that the urethral opening can stay near the tip of the penis and does not need to get “unzipped” backwards.
