I have problem of excessive urination and problem retaining urine in bladder after 5-10 mins of drinking water. Feel constant urge n pressure in abdomen to urinate. Need to get up several times at night to urinate. Got a urine routine test done and only specific gravity is low else its normal. Culture is negative. Got whole abdomen ultrasound and it screened out a 2.7mm renal calculus on right
kidney. Never really had any pain or discomfort other than urine frequency problem. Want to know, what is the cause or if a small stone can cause all the trouble?
