Obstructive uropathy

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.

Obstructive uropathy is blockage of urinary flow, which can affect one or both kidneys depending on the level of obstruction. If only one kidney is affected, urinary output may be unchanged and serum creatinine can be normal. When kidney function is affected, this is termed obstructive nephropathy. Hydronephrosis refers to dilation of the renal pelvis and can be present with or without obstruction. A variety of conditions may cause obstructive uropathy.
