Alternate Names : Post-Renal Nephropathy
Obstructive uropathy is a blockage of the normal flow of urine somewhere along the urinary tract.
What is going on in the body?
The urinary tract consists of the kidney, the bladder, the ureters, and the urethra. Obstruction can occur anywhere along this tract. Obstruction of urine flow increases the pressure to the kidney and can result in acute renal failure.
What are the causes and risks of the condition?
Obstructive uropathy may be caused by:
urethral strictures, or narrowing of the urethra
pressure from nearby tumors
scarring from previous radiation therapy
urinary tract infection
neuromuscular disorders, such as diabetic neuropathy
Obstructive uropathy is more common in a person with:
sickle cell anemia
benign prostatic hyperplasia (BPH)
history of kidney stones
history of radiation therapy
certain congenital disorders that affect the urinary tract
