Video - Postrenal azotemia

Postrenal azotemia is a condition characterized by an excessive level of nitrogen-containing waste products in the bloodstream (azotemia) due to obstruction of the urinary tract. Postrenal azotemia can be caused by congenital abnormalities such as vesicoureteral reflux, blockage of the ureters by kidney stones, pregnancy, compression of the ureters by cancer, prostatic hyperplasia, or blockage of the urethra by kidney or bladder stones. Postrenal azotemia can lead to kidney failure if left untreated. Treatment typically involves medical or surgical interventions to remove the obstruction.
