Urethral stricture: symptoms, causes, and treatment

Understanding the structure of the urethra: key aspects

Urethral stricture, or narrowing of the urethral passage, is a pathological condition characterized by a reduction in the lumen of the urethra due to scar formation. This can cause difficulties in urination, pain, and even complete closure of the urethra. The causes of stricture can include various injuries, inflammatory processes, or surgical interventions, which necessitates a comprehensive approach to the treatment of this condition.

Etiology of urethral stricture

The stricture of the urethra can have various causes. One of the main causes is trauma, as mechanical trauma (for example, after urethrotomy) or surgical interventions can lead to the formation of a stricture. Diseases such as inflammatory processes or infections can also contribute to the development of urethral stricture. Less commonly, urethral stricture may have a genetic predisposition or be associated with certain autoimmune diseases.

It is also important to note that a chronic established urethral stricture can be caused by uncontrollably growing scar tissue due to recurrent irritation or inflammation processes in the urethra. The interaction of etiological factors can be complex and diverse, which underscores the importance of a thorough medical analysis to determine the individual causes of urethral stricture development.

  • Injury: Mechanical injury, surgical interventions, or urethrotomy may cause urethral stricture.
  • Inflammatory processes: Chronic autoimmune diseases or urinary tract infections can contribute to the formation of strictures.
  • Genetic predisposition: Some forms of urethral stricture may be associated with hereditary factors.
  • Scar tissue formation: Uncontrolled growth of scar tissue due to recurring inflammatory processes can lead to stricture.
  • Autoimmune diseases: Some autoimmune conditions may be accompanied by the formation of urethral stricture due to the immune system’s impact on the urethral tissues.

Clinical picture of urethral stricture

The clinical picture of urethral stricture usually depends on the location and severity of the stenosis. Patients may present various symptoms, including difficulty urinating, pain during urination, increased frequency of urination, the feeling of an unemptied bladder, blood in the urine, urinary tract infections, and even urinary incontinence. These symptoms can be both acute and chronic, and they impact the quality of life of patients.

Diagnosis of urethral stricture includes physical examination, urethroscopy, urethrography, and sometimes additional methods such as ultrasound and voiding urethrography. It is important to detect urethral strictures in a timely manner, as this allows for the initiation of appropriate treatment and prevents potential complications associated with this condition.

  • Difficulties urinating: Patients may experience difficulties when urinating due to a narrow section of the urethra.
  • Pain during urination: A feeling of discomfort or pain when urinating can be one of the symptoms of urethral stricture.
  • Increased frequency of urination: Irregularities in urination caused by urethral stricture may lead to an increased frequency of urination.
  • Presence of blood in urine: Urethral stricture can cause irritation of the blood vessels around the urethra, leading to blood in the urine.
  • Urinary tract infections: Obstruction caused by urethral stricture can contribute to the development of urinary tract infections, which may also manifest as a burning sensation or severe discomfort during urination.

Expert opinion on the treatment of urethral stricture

The treatment of urethral stricture can be individualized depending on the specific case, location, and severity of the stenosis. Experts in urology generally strive to preserve the urethra and its function, preferring methods of reconstruction and dilation of the urethra. Currently, methods of endoscopic reconstruction of the urethra, such as balloon dilation, the use of stents, and surgical interventions like urethroplasty, are widely employed.

Experts recommend a comprehensive approach to the treatment of urethral stricture, including a combination of conservative and surgical methods based on the individual characteristics of each case. The decision on the choice of treatment method should be made after a retrospective analysis of the characteristics of the stricture, clinical symptoms, and anticipated treatment outcomes, taking into account possible complications and side effects.

Methods for diagnosing urethral stricture

The diagnosis of urethral stricture is carried out using various methods, including physical examination, urethroscopy, urethrography, and urethral visualization. Physical examination may reveal signs of compression and stenosis of the urethra. Urethroscopy is an important method for visualizing the structure of the urethra and assessing the location and degree of stenosis. Other methods, such as ultrasound, may be used for a more detailed study of the structures of the urinary system.

Urethrography and voiding urethrography are specialized methods that allow for a more detailed and accurate assessment of urethral stenosis, as well as determining the necessity and nature of therapeutic interventions. The comprehensive application of various diagnostic methods allows for the determination of the nature and extent of the urethral stricture, facilitating the selection of the optimal approach to treating this condition.

  • Physical examination: Includes inspection and palpation of the urethra to identify signs of stenosis and compression.
  • Urethroscopy: An endoscopic method that allows for a visual assessment of the structure of the urethra, determining the location and degree of stenosis.
  • Ultrasound examination: Can be used for additional evaluation of the urogenital system structure and identifying possible changes.
  • Urethrovisualization: A special method that allows for a more detailed study of the structure of the urethra and determining the nature of the stricture.
  • Urethral micturition visualization: Allows for a more accurate assessment of the degree and localization of the urethral stricture for subsequent treatment planning.

Approaches to the treatment of urethral stricture

The treatment of urethral stricture depends on the degree of stenosis, its location, the severity of clinical symptoms, and the overall condition of the patient. The main treatment methods include urethrotomy, balloon dilation, stent placement, urethroplasty, and regular urethral stimulation. In cases of complicated or progressive strictures, surgical intervention may be required.

An individual approach to the treatment of urethral stricture involves assessing the risks and benefits of each procedure in conjunction with the specific needs and desires of the patient. It is important to discuss all possible treatment options with the patient, explain the advantages and risks of the methods, and also consider the prognosis and the possibility of complications with each type of therapy.

  • Urethrotomy: Surgical incision of the stricture to restore the lumen of the urethra.
  • Balloon dilation: A technique in which a dilation balloon is inserted into the urethra and inflated to rupture the stenosis.
  • Stenting: Placement of a metal or silicone stent to maintain the lumen of the urethra.
  • Urethroplasty: A surgical procedure for the reconstruction or replacement of the urethra.
  • Urethral stimulation: Use of special urethral devices to improve the lumen of the urethra and reduce the stricture.

Prevention measures for urethral stricture

Prevention of urethral stricture includes the rational use of bladder catheterization, especially in the case of surgical interventions, strict adherence to hygiene rules and care for the urinary system, as well as timely and adequate treatment of urinary tract infections. Patients should avoid prolonged self-conducted urethral catheterization procedures, as excessive use of the catheter can increase the risk of developing a stricture.

Moreover, awareness of risk factors associated with possible injuries to the urinary system and timely consultation with a doctor at the first signs of disease contributes to timely diagnosis and treatment, which is crucial for preventing the development of urethral stricture. Careful adherence to specialists’ recommendations for the care of the urinary system after surgeries or other medical procedures also helps reduce the risk of this disease.

  • Avoid excessive use of urethral catheters, as this may increase the risk of developing urethral stricture.
  • Maintain strict hygiene of the urogenital system and monitor the condition of the bladder to prevent the development of infections.
  • Follow your doctor’s recommendations for care of the urogenital system after surgical interventions.
  • Consult a specialist at the first signs of urogenital system pathology to timely initiate treatment and prevent complications, including urethral stricture.
  • Avoid self-manipulation of the urethra or urogenital system without a doctor’s prescription to prevent possible injuries and complications.
