What is Urethral Stricture?
Urethral stricture is a condition where scar tissue forms inside the urethra — the tube that carries urine from the bladder out of the body — causing it to narrow and restrict urine flow. It can develop gradually and is often confused with other conditions like benign prostate enlargement.
Left untreated, urethral stricture can lead to urinary tract infections, bladder damage, and kidney complications. Early diagnosis and the right treatment approach are key to a complete recovery.
1
Injury / Infection
Trauma, catheterization, or infection damages urethral lining
2
Scar Tissue Forms
Healing process creates fibrous scar that narrows the urethra
3
Restricted Flow
Narrowing progressively worsens, causing pain and poor stream
What Causes Urethral Stricture?
Urethral InjuryTrauma from accidents, falls, or pelvic fractures — most common cause.
CatheterisationLong-term urethral catheter use causes irritation and scarring.
Infections (STIs)Gonorrhoea and other sexually transmitted infections can cause scarring.
Previous SurgeryUrological procedures like TURP or hypospadias repair may cause stricture.
InflammationLichen sclerosus — a chronic inflammatory skin condition affecting the urethra.
IdiopathicIn some cases, the exact cause cannot be identified.
How It Presents
Weak or slow urine stream
Straining to urinate or incomplete emptying
Spraying or split urine stream
Frequent urinary tract infections
Pain or discomfort during urination
Urinary retention in severe cases
Stricture Grading
Mild
Slight narrowing, mild symptoms
Moderate
Noticeable flow restriction
Severe
Near-complete blockage, retention risk
Treatment Options
01
Preferred for mild
Urethral Dilation
Gradual widening of the stricture using dilators. Simple and quick — but may require repeat procedures as stricture can recur.
02
Minimally invasive
Direct Visual Internal Urethrotomy (DVIU)
Endoscopic incision of the scar tissue under direct vision using a cold knife or laser — done as day surgery with quick recovery.
03
Gold standard
Urethroplasty — Surgical Reconstruction
Permanent repair by excising or patching the scarred segment using the patient's own tissue (buccal mucosal graft). Offers the highest long-term success rate of 85–95%.
04
Emergency
Suprapubic Cystostomy
Temporary bladder drainage for acute urinary retention — provides relief while planning definitive surgical repair.
