 I am Dr. Nag Subramaniam, Consultant Urologist at Dr. Malathi Manipal Hospital, Jainagar, Bangalore. Today we will discuss one of the causes for kidney disease, a surgical cause which is common these days due to changing lifestyles. It is all about the stone disease. Urinary stone was not an important cause of renal failure a few decades ago but due to changing lifestyles and dietary changes. Now urinary tract stones have become very common and has also become an important cause for producing renal failure. Now there are options available today both surgically and otherwise to treat urinary stones in various situations. These stones are generally formed due to the lack of water or dehydration along with dietary habits. Now the methods of treatment include weight and watch policies, surgery and followed up with lifestyle changes whether dietary requirements etc. Now these changes and treatment go a long way in preventing loss of kidney function over a period of time. This is an important aspect which everybody has to know on the occasion of the world kidney day which is celebrated or which is remembered basically to prevent renal failure due to different causes.
