Urinalysis in patients on chronic hemodialysis.

To determine what urinalysis findings are normal in patients maintained on chronic hemodialysis, we have studied the urine in 25 such patients. In end stage renal disease correlation with the original disease is lost, and urine characteristically contains many white blood cells and frequent white blood cell casts; microscopic hematuria is unusual even in patients whose original disease was a proliferative nephritis.
