Obstructive uropathy is a structural or functional hindrance of normal urine flow,^[1] sometimes leading to renal dysfunction (obstructive nephropathy).

It is a very broad term, and does not imply a location or etiology.

Causes

It can be caused by a lesion at any point in the urinary tract.^[2]

Causes include urolithiasis^[3] and ureteral herniation.^[3]

Symptoms

Symptoms, less likely in chronic obstruction, are pain radiating to the T11 to T12 dermatomes, anuria, nocturia, or polyuria.

Diagnosis

Diagnosis is based on results of bladder catheterization, ultrasonography, CT scan, cystourethroscopy, or pyelography, depending on the level of obstruction.

Treatment

Treatment, depending on cause, may require prompt drainage, instrumentation, surgery (eg, endoscopy, lithotripsy), hormonal therapy, or a combination of these modalities.
