Urethral stricture is a condition in which urine flow is restricted as a result of the inner diameter of the urinary channel (urethra) narrowing for various reasons. This narrowing makes it difficult for urine to be eliminated and can, over time, negatively affect both bladder function and kidney health.
The disease usually progresses insidiously and initially manifests itself with mild urinary complaints. However, when left untreated, it can lead to serious urinary retention (inability to urinate), recurrent infections, and damage to the upper urinary system.
Causes of Urethral Stricture
Urethral stricture can occur through different mechanisms:
Traumatic causes
- Pelvic area injuries
- Falls and traffic accidents
- External traumas that cause urethral damage
Medical procedures
- Trauma due to the use of a urinary catheter
- Damage occurring after endoscopic procedures
- Scar tissue that develops after surgical operations
Infections
- Recurrent urinary tract infections
- Sexually transmitted diseases
- Tissue damage that develops after chronic urethritis
Other causes
- A congenitally narrow urethral structure
- Excessive scar tissue formation during the healing process
- Rare inflammatory diseases
Symptoms of Urethral Stricture
Urethral stricture usually progresses slowly and becomes more pronounced over time:
Symptoms related to urination
- A weak and thin urine stream
- Delay in starting urination
- Intermittent urination
- The need to strain when urinating
- A prolonged urination time
Voiding problems
- A feeling that the bladder is not fully emptied
- Dribbling after urination
- A recurrent need to urinate
Signs of infection
- Frequent urinary tract infections
- Burning and a bad odor in the urine
- Prostate involvement over time
Advanced-stage symptoms
- Complete urinary obstruction (acute retention)
- Bladder enlargement
- Enlargement of the kidneys (hydronephrosis)
- Deterioration of kidney function
Diagnostic Methods
The diagnosis of urethral stricture requires a multifaceted evaluation:
Urodynamic tests
- Uroflowmetry (measurement of urine flow rate)
- Bladder voiding evaluation
Imaging methods
- Retrograde urethrography (the gold standard imaging)
- Voiding urethrography
Endoscopic evaluation
- Direct urethral imaging with cystoscopy
- Determination of the location and length of the stricture
Urethral Stricture Treatment
Treatment is planned according to the severity, length, and recurrence status of the disease.
Endoscopic and interventional treatments
- Urethral dilation (widening with a balloon or dilators)
- Internal urethrotomy (endoscopic incision of the stricture)
These methods provide relief in the short term, but there is a risk of recurrence.
Surgical treatment (permanent solution)
In advanced and long-segment strictures, the most effective method is surgery:
Urethroplasty (reconstructive surgery)
- Removal or repair of the narrowed segment
- Creating a new channel with healthy tissue
- Using a tissue graft if necessary
Urethroplasty is currently the permanent treatment method with the highest success rate.
The Importance of Urethral Stricture
When left untreated:
- Urinary retention can develop
- The bladder muscle can be permanently damaged
- The risk of kidney failure can arise
- Frequent infections occur
- Quality of life declines seriously
Clinical Summary
Although urethral stricture can be managed with simple procedures in the early period, it is a serious urological problem that requires complex surgery in advanced cases. The best results are achieved with correct patient selection and appropriate surgical techniques.
Frequently Asked Questions
Yes. In some patients treated especially with endoscopic methods, re-narrowing can be seen over time. This risk is lower with surgical repair.
No. Although there are procedures that provide mild relief, the permanent solution is usually surgery.
In mild and short-segment strictures, interventional methods can be tried, but in advanced cases, surgery is necessary for a permanent solution.
- Inability to urinate
- Bladder enlargement and muscle weakening
- Kidney damage
- Recurrent infections
Yes. Because the structure and function of the urinary channel are affected, ejaculation and comfort can be impaired.
In terms of long-term success, urethroplasty surgery is the gold standard.
Yes. Traumatic or long-term catheter use in particular can lead to urethral damage.
Excessive scar formation during the tissue healing process and inadequate treatment techniques can increase the risk of recurrence.
Retrograde urethrography and cystoscopy are the most important diagnostic tools.
Yes. When left untreated, it is a serious disease that can even affect kidney function.
It varies according to the treatment method; after surgery, short-term catheter use and follow-up are usually needed.
