Do ultrasound examination quickly hold urine can be through drinking more water, appropriate walking; or use diuretic drugs to quickly produce urine.
1. Drink more water: drink a lot of water about 30 minutes before the examination, generally drink 500~1000ml of water, and walk appropriately after drinking water most people will have a lot of urine production in about 30 minutes.
2. Oral diuretic drugs: If there are special circumstances, such as patients with renal failure, cardiac failure, nocturia production is slow. Diuretic drugs, such as furosemide, can be used to promote urine production. But the drug needs to be used under the guidance of a doctor.
Overall, it is best to consult the doctor before doing ultrasound to see if you need to hold your urine, so that you can prepare in advance to avoid too little urine in the bladder during the examination to affect the results.
