The bladder is a balloon-shaped organ in the pelvis area whose main function is to store urine.
Urethral stricture could be defined as the narrowing of the urethra due to any reason. This problem may or may not impact the flow of urine out of the bladder.
- Trauma caused by injury or accidents, consequently leading to damage to the urethra or bladder
- Pelvic injury
- Earlier procedures involving urinary catheters, surgeries and cystoscopy.
- Earlier prostate surgery such as TURP or Transurethral Resection of the Prostate.
- Urethral Cancer.
- Infections of the urethra including sexually transmitted diseases such as urethritis, gonorrhea, and chlamydia.
- Previous hypospadias surgery.
- Congenital abnormalities of the urethra.
- Experiencing difficulty in starting urine flow.
- Pain while urinating.
- Urinary tract infection (UTI).
- Urinary retention.
- Inability to fully empty the bladder.
- Reduced urine stream.
- Dribbling of urine.
- Double streaming urine.
- Blood in the urine.
- Urinary incontinence.
- Pelvic pain.
- Discharge from the urethra.
- Decreased ejaculation force.
The diagnosis and tests conducted for evaluating urethral stricture include:
- Evaluation of medical history.
- Comprehensive physical examination.
- Additional diagnostic tests such as Urinalysis (UA), urine culture, and urethral culture.
- Imaging and endoscopic studies such as Ultrasound of the urethra, Retrograde urethrogram, Anterograde cystourethrogram and Cystourethroscopy.
Surgery is the only option for individuals who have severe symptoms of urethral narrowing. Surgery may be recommended to patients if they have the following symptoms:
- Severe problems during urination
- Urinary retention
- Kidney stones in the bladder
- Frequent urinary tract infections
- Increase in post-void residual
- If all the other traditional measures have failed
Different types of surgical procedures are performed for treating urethral strictures. Some of the common procedures include:
- Urethral dilation
- Optical Urethrotomy
- Open urethral reconstruction
Urethral dilation is a common technique used for the treatment of urethral strictures. This procedure is generally done under local or general anesthesia. In this process, thin rods of varying diameters are gently inserted into the urethra through the tip of the penis so as to open up or widen the urethral narrowing without causing damage to the urethra. This procedure usually has to be repeated from time to time, as strictures have the chance of recurring. Sometimes, patients are given the necessary instructions and dilation equipments to perform the urethral dilation at home as required.
Endoscopic optical Urethrotomy
Urethrostomy refers to an endoscopic procedure that is generally performed under general anesthesia. An endoscope is inserted into the urethra to clearly view the stricture. Then, a small knife is passed through the endoscope in order to sever the stricture lengthwise to facilitate the smooth flow of urine. A urinary catheter is inserted and kept in position for some days while the incision is healing.
Open reconstruction involves various techniques for the correction of urethral strictures. Some surgeries are performed under general anesthesia and may involve opening the urethra to fix the stricture. In some, the region of scarring is separated and the remaining urethra is rejoined. In some others, after removing the scar tissue, a graft from the interior of the cheek namely buccal mucosa or a skin flap is used to create a reconstructed urethra.
Your urologist would recommend the procedure that is suitable for you.
