ABSTRACT
OBJECTIVE: The purpose of this study is to evaluate the uroflow parameters of the pregnant women before delivery and immediate postpartum period. METHODS: Forty four patients delivered by spontaneous vaginal delivery (NVD group) and 46 patients by Cesarean section (C/SEC group) and 28 non-pregnant young women (Control group) were included in this study. Uroflow were checked 1 day before and 2 days after delivery by Jupiter 8000 (FM Wiest(R)) uroflowmetry. Mean value of the uroflow parameters in each group was compared using ANOVA t-test. For continuous data, linear associations with each of the uroflow parameters were assessed using a Pearson correlation coefficient. RESULTS: Maximal (18.48+/-5.21 mL/sec) and mean flow rate (9.45+/-3.73 mL/sec) of pregnant women were lower than control group (22.75+/-5.14 mL/sec), and were not changed after delivery (18.79+/-6.03 mL/ sec). Total flow time of pregnant woman (14.06+/-6.09 sec) was longer than control group (8.05+/-5.32 sec) before delivery, and increased after delivery especially after cesarean delivery. Time to peak flow of pregnant women (8.44+/-9.48 sec) was shorter than control group (16.33+/-6.11 sec) before delivery, and was similar to control group after delivery. Total voided volume (121.39+/-50.17 mL) was less than control group before delivery, and was increased after delivery (246.77+/-127.42 mL). Total voided volume after delivery was not different with control group statistically. CONCLUSION: There was no statistically differences before and after delivery in maximal flow rate, but was lower than non-pregnant women. Total flow time was much prolonged after delivery, especially after cesarean delivery. Time to peak flow and voided volume were restored to levels of non-pregnant women after delivery.
