Hi lybrate-user, small stones inside the kidney cannot be removed within a few days. Only painful stones (which are blocking the ureter) get passed within a few hours to few days.
Moreover, 2 mm stone cannot be diagnosed with accuracy in ultrasound
. It will not harm you immediately. Just drink a lot of fluids and take citrus fruits regularly. Get a repeat ultrasound after 3 months.
, you need to be evaluated directly by a Urologist
. If there is an underlying precipitating factor, that needs to be corrected. If no underlying factor is found, you can follow general precautions for preventing UTI like increased fluid intake, voiding after intercourse, proper toilet hygiene, avoiding constipation
, taking curd regularly etc. Sometimes you may need low dose antibiotic prophylaxis. This will be decided by your Urologist.
Wish you good health
