I am having frequent urination problem for the past 4 days. I am going to pass urine almost 16 times a day. KFT is normal, pre diabetes, Urinary Routine is normal. Diagnosed with 3.1 mm Kidney Stone in Left Kidney. The doctor has prescribed medicine for OAB but nothing for Kidney Stone. How do I make sure that Kidney stone size does not increase and it comes out quickly? Also why exactly I have this frequent urination problem. My urine osmolality for first morning urine after 3 hours of sleep is 341 and Specific Gravity is 1.025
