What is Post obstructive uropathy?

By definition, post-obstructive diuresis is the condition of prolonged urine production of at least 200 cc for at least two consecutive hours immediately following the relief of urinary retention or similar obstructive uropathy. It may also be defined as more than 3,000 cc over 24 hours.[6]

What secondary condition can develop because of an obstructive uropathy?

Obstructive uropathy is structural or functional hindrance of normal urine flow, sometimes leading to renal dysfunction (obstructive nephropathy).

Is obstructive uropathy reversible?

Prognosis depends on the underlying etiology of the obstruction. An acute urologic obstruction is more likely to be reversible and less likely to produce damage to the kidney filtration system or other functions. However, chronic obstruction produces worse long-term effects on renal function.
