Things

Procedure

Under local anaesthesia a ventral urethral meatatomy can be performed by inserting the needle into the skin fold from the under side.
After meatatomy, a paediatric meatal dialator is passed to prevent cut edges from sealing together.
The child’s parents are instructed to separate the edges gently with the tip of the tube 3 times a day for 7-10days

In adults
Suturing at the 3 places is necessary to approximate the urethral mucosa and control bleeding at a) the apex
b) one on either side
Dorsal meatatomy:
It is performed by Y-V plasty after the excision.

Complication
1. Bleeding
2. Re-Stenosis
