Decreased consumption of water, excessive intake of non-vegetarian food and alcohol are risk factors. Those accustomed to a sedentary life and bedridden patients are also prone to renal calculi.

Pain is the most prominent symptom which aggravates on movement, especially climbing, horse-riding, running etc. It originates from the back and radiates downwards and towards the front. If the stone injures the kidney, ureters, bladder or the urethra, it will result in bleeding which will show up in the urine.
