Generally speaking, whether you need to hold your urine for an ultrasound is related to the part of the body being examined and the items being examined. Some color ultrasound examinations need to hold urine, and some do not.
Color ultrasound is a non-radiation, non-traumatic examination method, which is widely used in clinical practice.
Under normal circumstances, if it is a pregnancy ultrasound examination, etc., you need to hold urine. Transvaginal ultrasound, transrectal ultrasound, etc. do not require urine holding. In the case of female gynecological ultrasound examinations other than abdominal, you need to hold your urine. In the case of ultrasound of the bladder and ureter, and ultrasound of the male urinary prostate, you also need to hold your urine.
For ultrasound examinations that require urine holding, it is recommended to drink 500 milliliters of water before the examination to maintain a moderate to high urine output. In addition, it is important to consult your doctor about whether you need to hold your urine and to cooperate with your doctor.
