Urethroplasty is a surgical procedure conducted to correct scar tissue blockage of the urethra called urethral stricture. The urethra is the tube that carries urine from the bladder (through the penis in males) to the outside of the body. A urethral stricture can occur anywhere in the urethra. A urethral stricture is a scarred or hardened area that causes narrowing of the caliber of the urethra. The stricture eventually reduces or obstructs the flow of urine out of the bladder, making it difficult to urinate. The bladder therefore must work harder to push the urine through the narrowed area of the urethra.
Urethroplasty is performed under general anesthesia. Two Urethroplasty techniques are commonly used:
Anastomotic Technique: In this method of Urethroplasty, the narrowed part of the urethra is cut and the proximal and distal parts of the urethra are re-joined, a Foley's catheter will be left in for the next 2 weeks to ensure complete healing and repair. This method of Urethroplasty is used for small urethral strictures i.e. less than 2 cm wide. Tissue Transfer: In this method, 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 a free graft.
No heavy lifting is recommended for 4 weeks after Urethroplasty surgery. Driving is also not advised for 3 weeks. Sexual activity can be resumed only after 6 weeks.
