Understanding Urethral Strictures

Urethral strictures are abnormal narrowings of the urethra that can cause various urinary symptoms, most commonly presenting with decreased urinary stream and incomplete bladder emptying, but may also include urinary tract infections, epididymitis, rising post-void residual urine volume, or decreased force of ejaculation 1, 2
In developed countries, the most common etiology is idiopathic, followed by iatrogenic causes, such as catheterization, instrumentation, transurethral surgery 1, 3
Trauma is a more common cause of urethral strictures in developing countries 3

Clinicians should include urethral stricture in the differential diagnosis of men who present with decreased urinary stream, incomplete emptying, dysuria, urinary tract infection, and rising post-void residual 1, 2, 6
Diagnosis requires urethro-cystoscopy, retrograde urethrography, voiding cystourethrography, or ultrasound urethrography 2, 6
Determination of urethral stricture length and location allows for informed discussion about treatment options 6, 7

Urinary stone incidence varies by geography, climate, ethnicity, diet, and genetics, with prevalence ranging from 1% to 20% 5
High-income countries such as Sweden, Canada, and the USA have rates exceeding 10% 5
There is emerging evidence linking nephrolithiasis to the risk of chronic kidney disease 5

Nephrotoxicity is one of the most commonly cited health effects of uranium exposure 4
Studies suggest uranium's main target in the body is the kidneys, with even low doses potentially resulting in kidney effects 4
However, research suggests nephrotoxicity may result from high-level acute exposure rather than chronic low-level repeated exposures 4
