Working with kidney patients since 1991.
Dr. Henry Wehrum opened Denison Renal Care near the old Doctors' North Hospital on Dennison Avenue. The goal was to provide the very best care to kidney patients in the Columbus area. The practice provides personal and expert care for people with chronic kidney disease, kidney failure, and kidney transplantation. The practice out grew its former location on Dennison Avenue and moved to its current location in Grandview in 2001. Shortly after the new office opened its doors, the terrible tragedy of 9/11 occurred. To commemorate those lives lost, the office prominently displays the American flag to this day. The office welcomes new patients of every color, religion and country of origin.
Areas of Practice
Kidney disease impacts millions of Americans every year. Chronic kidney disease – or renal failure – simply means that your kidneys are no longer functioning properly. Kidneys serve very important roles in your health, including the removal of waste from your blood supply. Left untreated, renal failure leads to severe health issues and ultimately can result in death. Treatment is possible, and we are here to help.
Dialysis is a treatment that does some of the things done by healthy kidneys. It is needed when your own kidneys can no longer take care of your body's needs.
See our list of dialysis units that we visit.
Hypertension is defined as having a blood pressure higher than 140 over 90 mmHg. The kidneys are supplied with a dense network of blood vessels, and high volumes of blood flow through them. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. These damaged arteries are not able to deliver enough blood to the kidney tissue leading to kidney disease.
Kidney stones (renal lithiasis, nephrolithiasis) are small, hard mineral deposits that form inside your kidneys. The stones are made of mineral and acid salts. Our doctors can recommend treatment and preventive ways to reduce your risk of recurrent kidney stones if you're at increased risk of developing them again.
A kidney transplant is an operation (surgery) in which a person with kidney failure receives a new kidney. When kidneys fail, there are two main treatment choices: dialysis or transplant. Many people feel that a successful kidney transplant provides a better quality of life because it may mean greater freedom, more energy and a less strict diet.
Interventional Nephrology is a new and emerging subspecialty of Nephrology that helps maintain vascular access for patients undergoing hemodialysis. We work with the Vascular Access Center to coordinate these services.
