ABSTRACT
Uterine involution was studied ultrasonographically in 130 patients. The patients included 4 groups: Group I of 40 patients, 20 of them were primiparas and 20 multiparas to study the effect of parity on the rate of involuation. Group II of 30 patients, 15 of them delivered vaginally and the other 15 delivered by cesarean section to study the effect of the mode of delivery on uterine involution. Group III of 20 patients, 10 of them were lactating and the other 10 non-lactating to study the effect of lactation on uterine involution. Group 1 V of 40 patients, 20 of them received ecbolics and the other 20 did not to study the effects of ecbolics. The results have shown that parity and ecbolics have no effects on the rate of uterine involution. The rate of uterine involution was faster in breast feeders and those delivered vaginally compared to non-breast feeders and those delivered by cesarean section [P < 0.05]. Ultrasonography proved to be a useful method for assessing uterine involution
