Obstructive uropathy - Symptoms, Causes, Images, and Treatment Options

Diseases

Highlights & Basics

Key Highlights

Obstructive uropathy is blockage of urinary flow, which can occur at any level in the urinary tract. It may affect one or both kidneys, depending on the level of obstruction.
A number of underlying conditions can result in obstructive uropathy, most commonly urolithiasis, ureteropelvic junction obstruction, and benign prostatic hyperplasia.
Initial treatment in the acute setting is directed at relieving pressure on the kidneys to prevent irreversible renal damage. This may involve a urethral catheter, ureteric stent, or nephrostomy tube, depending on the level and cause of obstruction.
Subsequent treatment is targeted toward treating the underlying cause.
Infection within an obstructed system must be treated promptly.
