Obstructive uropathy
From Wikipedia, the free encyclopedia
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 cause.
Symptoms, less likely in chronic obstruction, are pain radiating to the T11 to T12 dermatomes, anuria, nocturia, or polyuria.[citation needed]
Causes
It can be caused by a lesion at any point in the urinary tract.[2]
Causes include urolithiasis,[3] posterior urethral valves and ureteral herniation.[3]
Diagnosis
Diagnosis is based on results of bladder catheterization, ultrasonography, CT scan, cystourethroscopy, or pyelography, depending on the level of obstruction.[citation needed]
