Urethroplasty is a surgical repair of the urethra to treat injuries or defects caused by trauma, medical procedures, or infections. There are several types of urethroplasty procedures that can be used depending on the location and severity of the damage. The surgery involves accessing and repairing the damaged part of the urethra by removing or rebuilding the strictured tissue. Grafts from the mouth, genitals, or rectum may be used to supplement the repair. After closing the incision, a catheter is placed to allow the urethra to heal while draining urine, and is usually kept in place for two weeks. Potential complications include bleeding, infection, erectile dysfunction,

3. URETHROPLASTY
Scar tissue repair of
urine channel
Surgical repair of an
injury or defect within
the walls of the urethra.
Trauma, iatrogenic injury
and infections are the
most common causes of
urethral injury/ defect
requiring repair.

10. INDICATION
URETHRAL STRICTURE – some parts of your urethra has become
narrower, blocking the flow of urine. Urinary strictures are much
more common in the men than women.
EPISPADIAS OR HYPOSPADIAS – congenital conditions that affect
your urethra, which were repaired in childhood. Blockage are
especially common in urethras that have previously been rebuilt.
SEVERE TRAUMA
17. What happen during urethroplasty
The incision to the muscle tissue to reach the urethra. The incision is typically
either on the underside of the penis, in scrotum and anus(perineum)
Location of the stricture identified, either removed or rebuilt depending on the
length and location.
If the blockage is longer, or located in the penile urethra, the surgeon will
harvest the mouth, genital or rectal tissue to supplement the incised(cut away)
tissue from the urethra.
The incision then closed and a small drain is placed.
The catheter allows the urethra to heal while urine is able to leave the
body.(usually keep for 2 weeks)
Muscle and skin closed up with stitches that absorbed by the body.
