Frequency and nocturia are the commonest and the earliest symptoms to develop in pregnancy [3]. These occur as early as the first trimester because of an increase in renal glomerular filtration rate and urine output, and with the fatigue of pregnancy more time is spent in bed at night. Pressure from an enlarged uterus or the descent of the presenting part with fetal engagement during late pregnancy would lead to a decrease in bladder capacity and an increase in urinary frequency. Eighty percent of pregnant women will experience urinary frequency at some stage during the pregnancy [31]. Increase in sodium excretion as well as the mobilization of dependent oedema at night is the major reasons for increased night-time voiding. Urinary hesitancy may occur in up to 27% of patients in the first two trimesters [3]. Cutner et al. assessed flow rates in pregnancy, adjusted for voided volume, and found no difference in women complaining of hesitancy or incomplete emptying compared with women with normal voiding
