If you have frequent urination and low urine volume, it is recommended that you go to the hospital for urine-related laboratory tests to clarify the specific causes.1. Infections in the urinary tract, such as acute urethritis, cystitis, pyelonephritis, etc., may occur with frequent urination. Because of the elevated sensitivity in the bladder, a small amount of urine is stored to produce a willingness to urinate, so each urine volume is not much. It is accompanied by painful urination, pain in the small abdomen or pain in the lower back, etc. A routine urine test and a urine culture test are required to confirm the diagnosis. After the diagnosis is confirmed, anti-infection treatment is needed to cure it.2. If stones exist in the urinary tract, such as bladder stones and stones in the lower ureter, strong urinary tract irritation can be produced. Patients will experience frequent urination, but not much urination each time, and it may be accompanied by pain in the area where the stone is located, such as pain in the small abdomen or lower back pain. Ultrasound examination of the urinary system is required to confirm the presence of stones, and extracorporeal shock wave lithotripsy or medication for stone removal is recommended.
