Pregnant patient. Initial imaging. Pregnant patients present with microhematuria at a rate similar to nonpregnant patients, and the rate of malignancy in this group is low [2,19]. Arteriography Kidney Arteriography is not used as a first-line imaging modality for the evaluation of microhematuria in pregnancy. There is no relevant literature regarding the use of arteriography for the initial evaluation of microhematuria. CT Abdomen and Pelvis CT is not used as a first-line imaging modality for the evaluation of microhematuria in pregnant patients secondary to the risks of radiation exposure to the fetus. The incidence of asymptomatic microhematuria in pregnant women is similar to nonpregnant women, and the rate of malignancy in this group is low [2]. CTU CTU is not used as a first-line imaging modality for the evaluation of microhematuria in pregnant patients secondary to the risks of radiation exposure to the fetus. The incidence of asymptomatic microhematuria in pregnant women is similar to nonpregnant women, and the rate of malignancy in this group is low [2]. MRU MRU MRU without and with IV contrast is not used as a first-line imaging modality for the evaluation of microhematuria in pregnant patients. The incidence of asymptomatic microhematuria in pregnant women is similar to nonpregnant women, and the rate of malignancy in this group is low [2]. MRU without IV contrast during pregnancy is a reasonable choice with a full workup after delivery once gynecologic bleeding and other benign causes (such as infection) have been excluded [2]. MRI with IV contrast should be avoided in pregnant patients because of uncertainty of effects of gadolinium contrast on the fetus. See the Safety Considerations in Pregnant Patients section below. MRI Abdomen and Pelvis The incidence of asymptomatic microhematuria in pregnant women is similar to nonpregnant women, and the rate of malignancy in this group is low [2].
