Urethral strictures is a condition where the urethra is narrow and restricts the urinary flow caused by an injury, instrumentation, infection or urethritis.
Urethral Strictures occur after a blunt trauma to the pelvis or urethra. Other causes include cancer of urethra or prostate, radiation therapy, sexually transmitted diseases, long term catheterization etc.
Symptoms Includes weak urine flow or decreased volume of urine, frequent and sudden urge to urinate, feeling of incomplete bladder emptying, pain and burning sensation during urination, urethral discharge, penile pain and swelling, dark urine output, and in severe cases inability to urinate.
After collecting medical history the urologist performs a physical examination of the penile area to check for redness or swelling.
To make a definite diagnosis the urologist may perform Cystoscopy and Urethrography.
Non Surgical Management:
The primary mode of treatment includes widening of the urethra by using an instrument called a dilator. The urologist passes the small wire through the urethra into the bladder and begins to dilate, over the time larger dilators are used to increase the width of the urethra.
Visual Internal Urethrotomy( VIU)
A simple surgical procedure performed under spinal or general anesthesia were the urologist inserts an endoscopic device called Urethrotome into the urethra and advances into the narrow portion of urethra then by using surgical blades a cut is made through the urethral stricture and then advance the endoscopic device into the bladder. A urinary catheter is placed for some days which helps in the healing process of the urethra.
