Urethroplasty is performed under anaesthesia. There are two Urethroplasty techniques are popularly used:
- Anastomotic urethroplasty - In this method of Urethroplasty, the narrowed part of the urethra is removed and the proximal and distal parts of the urethra are re-joined, a Foley’s catheter will be left in for 2-3 weeks to ensure complete healing and repair. This method of Urethroplasty is used for small urethral strictures i.e. less than 2 cm wide and for the stricture due to injuries due to road traffic accidents or any direct injury to the urethra.
- Substitution Urethroplasty (or) Tissue Transfer technique – Here the technique is used for the patients with lengthy (more than 2-3cm) strictures. In this method of Urethroplasty, Skin and Tissue is grafted from a non-hair bearing part of the body like the buccal mucosa or bladder mucosa. Free grafts like Full Thickness Skin Grafts or Split Thickness Skin Grafts can be used for this purpose. Tissue Transfer Urethroplasty can be also be carried out in 2 stages if sufficient local tissue is not available for a Skin Flap Procedure and local tissue factors are not suitable for free graft.
