From symptoms to treatment

1. SYMPTOMS

• Weak or spraying stream • Straining or dribbling • Repeated urinary infections

2. TESTING

• Flow test and bladder scan • Retrograde urethrogram, in the office • Cystoscopy

3. TREATMENT

• Dilation or urethrotomy for short, first-time strictures • Optilume for some recurrent ones • Urethroplasty for lasting repair

Surgical options →

An anterior urethral stricture is scar tissue that narrows the urethra between the tip of the penis and the area just under the prostate. It's the most common type of stricture I treat.

The three locations

  • Bulbar urethra: the segment behind the scrotum. The most common location, often from an old injury, an infection, or a catheter.

  • Penile urethra: along the shaft. Often linked to lichen sclerosus, prior hypospadias repair, or catheters.

  • Fossa navicularis and meatus: the tip of the penis. Frequently from lichen sclerosus or prior instruments.

What you might notice

A weak or spraying stream, straining, dribbling, getting up more at night, repeated urinary infections, or a stream that has slowly worsened over years.

How I evaluate it

A flow test and a bladder scan show how well you empty. A retrograde urethrogram, done in my office, shows the length and location of the scar, and a quick cystoscopy can confirm what it looks like from the inside. Those details decide the repair.

Treatment

Dilation or a cut through the scar (urethrotomy) can help short, first-time strictures, but they often come back. A drug-coated balloon (Optilume) is an option for some short, recurrent strictures. For strictures that keep returning, urethroplasty is the long-term fix: removing a short scar and rejoining the ends, or widening a longer one with a graft from inside the cheek.
