When we come across the term reversible renal failure, it indicates that there was a scope for the repair of renal lesions or complete recovery of renal function. Reversible renal failure is of great importance for the clinician/nephrologist attending to the patient, because he/she could be able to do something for the well being of the patient. Clinical end picture may be same in many renal disorders though the origins are so different. Acute stage is characterized by pain in back, fever and edema, a rise in blood pressure and such urinary changes as oliguria (low output of urine), high specific gravity of urine with high coloration. Presence of albumin, red blood cells (RBCs) and casts have also been observed in urine with low urea content. It has been observed that reversible renal failure is generally extra-glomerular in origin, but it may be nephritic type. Most of the cases with acute glomerulonephritis also make a complete recovery with therapy and dialysis. Tubular damage may also be repaired, as has been in the cases of mercuric chloride poisoning. Accumulation of nitrogenous waste products in blood is observed in these patients without any renal lesion on blood biochemistry and kidney biopsy evaluation. The condition may also be termed as extra-renal uremia or azotemia without corresponding renal lesion.
