How to have the urge to urinate quickly can be taken as follows: first, drink a lot of water in a short time, such as drinking about 500-800ml of water within half an hour, then you can produce the urge to urinate quickly. Because after drinking a lot of water, the blood volume increases, the amount of body fluid filtered by the kidneys increases, at this time the filtered urine increases, it can produce more urination. Secondly, oral diuretic drugs, commonly used are furosemide tablets, spironolactone, or dihydrocoumaric acid tablets, etc., which can produce a large amount of urine and a strong urge to urinate in about 10-15 minutes after oral administration. You can also use intravenous diuretic drugs, such as intravenous pushing furosemide injection, 10mg or 20mg, then you can produce a large amount of urine within 5-10 minutes, and produce the desire to urinate.
