Kidneys stones are a common condition. They are quite different from Gallstones which are formed in the Gall bladder. Gall stones are from bile concentration in the gall bladder. "Silent" Gallstones which are detected on an ultrasound done for another cause, can be left alone.

However, silent kidney stones should never be left alone. These can silently grow to a large size and cause kidney failure without the patient ever experiencing pain. Every patient of stone needs to be evaluated by blood tests, ultrasound and possibly CT-scan. Small stones 5 mm or less may pass out naturally, but should be monitored on Ultrasound to confirm clearance. Larger stones are cleared by a variety of Endoscopic Operations like Ureterorenorenoscopy, PCNL or ESWL. These need 1-2 days hospitalisation and have quick recovery. The stone removed should be analysed for contents so that appropriate preventive measure in diet and medicines can be started as soon as possible. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Hello, I am Sandeep Behura. I have done DM from BHU. I am a consultant Nephrologists in Delhi and I am practising in Noida also. Today I am going to talk about Acute Renal Failure which is a common problem.

Acute Renal Failure is characterized by the failure of the normal function of a kidney which occurs over a short period of time. Medically speaking, there is an accumulation of Nitrogen as a waste product in the body with fatuation of electrolyte imbalance associated with retention of fluid in the body which occurs over the period of hours to days.

The aetiology of Acute Renal Failure is varied. However, it is classified into 3;

• Prerenal ARF, which constitutes majority 55% of the cases.
• Entrance adrenal ARF, which contributes to about 45% adrenal failure.
• And 5% of the causes are Postrenal ARF

Coming to the Prerenal ARF, most of the causes are following;

• Massive dead loss, like following traffic accidents or a major surgery. 
• Following fluid loss like following diarrhoea, vomiting, patients having diabetes, patients with the cardiac problem may have Acute Renal Failure.

Intense Renal ARF is 2 types. These can be ischemic in nature or toxic in nature.
