Question

postrenal acute renal failure is characteristic of which one of the following conditions?
minimal - change nephrotic syndrome
cystitis
obstructive prostatitis with hyperplasia
congestive heart failure
polyarteritis nodosa

Explanation:

Postrenal acute renal failure is due to obstruction of urine flow after the kidneys (e.g., in the ureters, bladder, or urethra). Obstructive prostatitis with hyperplasia can cause urinary outflow obstruction (e.g., enlarged prostate blocking the urethra), leading to postrenal failure. Minimal - change nephrotic syndrome is a renal (intrarenal) disease. Cystitis is a bladder infection and usually doesn't cause postrenal failure. Congestive heart failure causes prerenal failure (due to decreased renal perfusion). Polyarteritis nodosa is a vasculitis affecting kidneys (intrarenal).

Answer:

Obstructive prostatitis with hyperplasia
