The urethral crest obstruction is a blockage or narrowing that occurs in the urethra, specifically in the region of the urethral crest, which is an anatomical feature located in the posterior part of the male urethra. This condition can affect urine flow, leading to difficulty in urination or complete blockage, depending on the severity.
Pathophysiology
Structure and Blood Supply
The urethra is a tube that carries urine from the bladder to the outside of the body. The urethral crest is a small ridge that runs along the back of the urethra in males. It has a role in urine flow and can cause issues if obstructed. Blood supply to the urethra is provided by the branches of the internal pudendal and inferior vesical arteries, ensuring that it stays healthy and functional.
Nerve Supply
The nerves that supply the urethra include the pelvic splanchnic nerves, which control the reflexes involved in urination. Nerve damage can impact bladder function and lead to symptoms such as incontinence or retention.
Types of Urethral Crest Obstruction
- Congenital Urethral Obstruction – Present from birth, often due to abnormal development.
- Acquired Urethral Obstruction – Caused by injury, infection, or scarring.
- Partial Obstruction – A narrowing of the urethra, leading to a slow stream or difficulty in urination.
- Complete Obstruction – A total blockage, preventing any urine flow.
- Recurrent Obstruction – Frequent episodes of obstruction that may require repeated interventions.
Causes of Urethral Crest Obstruction
- Congenital anomalies like posterior urethral valves.
- Infections such as urinary tract infections (UTIs).
- Scarring due to injury or surgery.
- Prostate enlargement in men.
- Bladder stones.
- Urethral strictures.
- Bladder neck obstruction.
- Tumors or cysts in the urethra.
- Inflammatory conditions like urethritis.
- Trauma to the urethra from accidents or medical procedures.
- Chronic use of urinary catheters.
- Hormonal imbalances affecting urinary tract health.
- Radiation therapy affecting the pelvic region.
- Pelvic organ prolapse.
- Fistulas (abnormal connections between organs).
- Neurogenic bladder (nerve-related issues).
- Medication side effects (e.g., anticholinergics).
- Dehydration leading to concentrated urine.
- Aging-related changes in the urinary tract.
- Involvement of other organs like the rectum or colon.
Symptoms of Urethral Crest Obstruction

- Nausea or vomiting (due to kidney involvement).
- Dark or cloudy urine.
- Change in urine odor.
Diagnostic Tests for Urethral Crest Obstruction
- Physical exam to check for tenderness or swelling.
- Urinalysis to detect infections or blood.
- Ultrasound to visualize the bladder and urethra.
- CT scan for detailed imaging of the urinary tract.
- MRI to evaluate soft tissue structures.
- X-ray with contrast dye (IVP) to see the urethra and bladder.
- Urodynamic tests to assess bladder function.
- Cystoscopy to directly observe the urethra and bladder.
- Urethral pressure profile to measure the pressure inside the urethra.
- Post-void residual urine measurement to check for incomplete bladder emptying.
- Bladder scan for volume and residual urine.
- Cystourethrogram (X-ray with contrast) to check for structural abnormalities.
- Flowmetry to measure the speed and volume of urine flow.
- Urine culture to detect infections.
- Electromyography to check nerve function.
- Kidney function tests (e.g., creatinine levels).
- Serum prostate-specific antigen (PSA) in men to rule out prostate issues.
- Urethral dilation test to determine the degree of obstruction.
- Radionuclide scan to check kidney function.
- Genetic testing if congenital abnormalities are suspected.
