Is it necessary to hold urine for a transvaginal ultrasound?

Holding urine is an important part of transvaginal ultrasound, as it helps doctors better examine lesions within the vagina and uterus. The purpose of holding urine is to elevate the uterus into a higher position, facilitating a more accurate assessment of the uterine structures. By filling the bladder, the uterus is lifted and positioned higher, which aids in visualizing internal uterine anatomy. To hold urine, patients should avoid urinating for a certain period before the examination so that the uterus is elevated and easier to visualize. Typically, urine should be held for about 3–4 hours, although this duration may vary depending on the individual patient's condition.
