[Uroflowmetry and ultrasound residual urine determination in pregnancy and post partum].

In order to estimate the influence of adaptational processes during pregnancy and post partum on micturition, uroflow-parameters (3) and residual urine were examined in 119 healthy women. Comparisons were made between women in the 1st, 2nd and 3rd trimester of pregnancy, women who were between 1 and 5 days post partum and nonpregnant, fertile women. Compared with the control group the mean flow was significantly lower during the 2. and 3. trimester. Time taken to achieve maximum flow was significantly higher after spontaneous delivery compared with the control group. During pregnancy and after delivery an increase in flow time could be shown. During the 3rd trimester time taken to achieve maximum flow was noticeably higher than in the other groups. Both mean and maximum flow were lower during pregnancy and after spontaneous delivery than in the control group. Residual urine increased mainly during the 1. trimester and showed the highest value after delivery. As all the investigated differences stayed within the standardized values, uroflowmetric investigations and ultrasonic residual urine estimation during pregnancy and after delivery are only necessary if suspicious symptoms on the part of the urinary tract exist.
