Obstructive uropathy may be caused by:
kidney stones
urethral strictures, or narrowing of the urethra
pressure from nearby tumors
scarring from previous radiation therapy
urinary tract infection
cancer
neuromuscular disorders, such as diabetic neuropathy
Obstructive uropathy is more common in a person with:
sickle cell anemia
diabetes mellitus
neuromuscular disease
pregnancy
cancer
benign prostatic hyperplasia (BPH)
history of kidney stones
history of radiation therapy

certain congenital disorders that affect the urinary tract
