Obstructive uropathy

Obstructive uropathy occurs when urine cannot drain through a ureter (a tube that carries urine from the kidneys to the bladder). Urine backs up into the kidney and causes it to become swollen (hydronephrosis).

Obstructive Uropathy
Obstructive uropathy is a very painful condition that affects the kidneys and urinary tract. It can lead to other complications throughout the body.

Obstructive uropathy occurs when the flow of urine is blocked. The kidneys continue to produce urine in the normal manner, but the urine does not drain properly because of the obstruction. This causes swelling of the kidneys (hydronephrosis).

Obstructive uropathy - unilateral - acute; Ureteral obstruction
Causes, incidence, and risk factors
Unilateral obstructive uropathy is most often caused by a kidney stone, although injury or other conditions could cause the disorder.

Obstructive uropathy explained
Problems involving the urinary tract are common complications. The kidneys filter waste products and excess fluid from the blood to make urine.

Obstructive uropathy is a blockage of the normal flow of urine somewhere along the urinary tract. The obstruction increases the pressure on the kidney and can result in acute renal failure.

Obstructive uropathy, anatomic abnormalities, and neuropathic urinary tract lesions such as compression of the spinal cord usually require surgical correction. Catheter drainage of an obstructed urinary tract aids in prompt control of UTI.

The urinary abnormality is an obstructive uropathy in which failure of nerve signals between the bladder and the spinal cord results in incomplete emptying of the bladder (neurogenic or neuropathic bladder).

Of particular importance is the fact that these anatomic changes may persist for up to 6 weeks postpartum and may be mistaken for other causes of obstructive uropathy.
