Background: Nephrectomies and nephroureterectomies specimen with neoplastic diagnosis provide a great opportunity to examine the background kidney parenchyma. This will help in exploring any microscopic abnormality that may affect the functional capacity of the residual renal tissue and assess the possible need for nephrologist intervention in maximizing the function of the residual renal parenchyma. Aim: Evaluation of this part of the kidney is overlooked in different centers around the world. Method: A total of 124 specimens of nephrectomies and nephroureterectomies performed at King Abdulaziz University Hospital between January 2010 and December 2019 were reviewed. The microscopic findings in the nonneoplatic parenchyma were documented. Furthermore, the extent to which these findings were initially identified, investigated, and reported was measured. Results: Hypertensive and diabetic nephropathy were among the most common findings in the diseased kidney. The nonneoplastic kidney was well sampled in 95% of the cases and mentioned in the report in 25% of the cases. Conclusion: Although, the evaluation of this part of the kidney is essential, and of great help for the patient prognosis, and quality of kidney function, it is overlooked in different centers around the world, and the causes behind this requires further exploration.
