Urethral Stenosis: Causes, Symptoms, Diagnosis, and Surgical Interventions

​

 

Urethral stenosis, a condition that affects the urethra and can cause significant urinary discomfort. In this section, we will explore the causes, symptoms, diagnosis, and surgical treatment options for urethral stenosis.

​

 

Causes of Urethral Stenosis:

​

 

Urethral stricture occurs when the urethra, the duct through which urine leaves the body, becomes narrowed or constricted. This can be caused by a variety of conditions, including urethral trauma, infection, inflammatory disease, previous surgery, radiation, or congenital factors. Scarring and scar tissue formation are often responsible for urethral stricture.

​

 

Symptoms of Urethral Stenosis:

​

Symptoms of urethral stricture can range from mild to severe and may include difficulty initiating or maintaining urinary flow, weak urinary flow, post-mineral drip, frequent and urgent need to urinate, pain or burning during urination, and recurrent urinary tract infections.

​

Diagnosis of Urethral Stenosis:

​

 

Diagnosis of urethral stenosis involves a thorough evaluation of the patient's medical history, physical examination, and specific diagnostic tests. These tests may include urethrocystoscopy, which allows the physician to examine the urethra internally using a flexible endoscope, imaging tests such as excretory urography or magnetic resonance imaging, and sometimes urodynamic tests to assess urinary flow and pressure.

​

 

Surgical Interventions for Urethral Stenosis:

​

 

The main treatment for urethral stricture is often surgical and aims to remove or dilate the narrowed area of the urethra to restore normal urinary flow. Some of the common surgical options include:

 

Urethral dilatation: This procedure involves the use of special dilators or catheters to gradually widen the urethra and improve urinary flow.

​

Internal urethrotomy:

During this procedure, the doctor makes an incision inside the narrowed urethra to remove scar tissue and restore urinary flow.

Urethral reconstruction: In more severe cases, urethral reconstruction surgery may be necessary,

​

Urethroplasty: Advantages, Disadvantages, and Complications

​

 

Urethroplasty is a surgical procedure used to treat urethral stricture by repairing or reconstructing the narrowed urethra to restore normal urinary flow.

Here is an overview of the advantages, disadvantages, and possible complications associated with this procedure

​

 

Advantages of Urethroplasty:

​

 

Restoration of urinary function: The main goal of urethroplasty is to restore normal urinary flow, allowing the patient to empty the bladder without difficulty. This can alleviate symptoms associated with urethral stricture and improve quality of life.

​

Reduction of symptoms: Urethroplasty can help reduce or eliminate symptoms such as difficulty urinating, weak urinary flow, pain or burning during urination, and recurrent urinary tract infections.

Reduction of dependence on catheters: In cases where patients are forced to use catheters to empty the bladder due to urethral stricture, urethroplasty can reduce or eliminate dependence on catheters, providing significant relief.

​

Disadvantages of Urethroplasty:

​

 

Possible need for general anesthesia: Urethroplasty may require the use of general anesthesia, which carries some risks and may require a longer recovery period than simple local anesthesia.

Possible postoperative complications: Like any surgical procedure, urethroplasty carries some risks of postoperative complications, including infection, bleeding, scar tissue formation, and recurrence of urethral stricture.

​

 

 

Complications of Urethroplasty:

​

 

Infection: Surgical wound infection is a potential complication of urethroplasty. It is important to follow postoperative guidelines to reduce the risk of infection and to consult your doctor if you develop signs of infection, such as redness, swelling, or discharge from the wound.

Recurrent stenosis: In some cases, despite surgery, urethral stenosis may recur over time. This may require further surgery or treatment to manage the recurrence.

Pain or discomfort: Some patients may experience pain or discomfort during the recovery period after urethroplasty. Your doctor may prescribe medications to relieve pain and provide instructions for managing discomfort during recovery.
 

​

Here are some of the most common types of urethroplasty:

​

 

Primary urethroplasty: This type of urethroplasty is first performed to treat urethral stricture. It involves removal of scarred or narrowed tissue and reconstruction of the urethra using tissue taken from other parts of the body, such as the mucosa of the mouth (buccal mucosa) or the skin.

Tissue graft urethroplasty: In this type of urethroplasty, graft tissue, such as buccal tissue or skin tissue, is used to reconstruct the narrowed urethra. The graft tissue is placed to widen the urethra and restore normal urinary flow.

Flap urethroplasty: During flap urethroplasty, a flap of tissue is taken from an area near the urethra, such as the foreskin or mucosa of the mouth, and is used to cover and widen the narrowed urethra. This type of urethroplasty can be used for complex or recurrent urethral strictures.

Urethroplasty with prosthesis: In some cases, when the urethral stricture is extensive or other urethroplasty options are not suitable, a prosthesis may be used to reconstruct the urethra. The prosthesis is placed to keep the urethra open and allow urinary flow. 

 

Laser urethroplasty: Laser urethroplasty is an innovative procedure that uses lasers to remove scar tissue and open the narrowed urethra. This technique can be advantageous in reducing bleeding and speeding up recovery.
