Preparation for ultrasound of the bladder

The study is carried out with a full bladder, so it is recommended to refrain from urinating for 3-4 hours before the study or take 1 liter of non-carbonated liquid 1 hour before the procedure. If it is impossible to tolerate and a strong urge to urinate, it is permissible to empty the bladder a little to relieve tension and re-drink a little liquid to achieve a full bladder by the time of the study. 

The study is not performed on an empty stomach, so you can eat and drink on the day of the procedure.
