analyzed effects of alpha-blockers (tamsulosin and doxazosin) on stone expulsion rate
, stone expulsion time, and treatment-emergent adverse events with four RCTs and one cohort study.
Many studies have shown the efficacy of MET in distal ureteric stones with primary aim of improving stone expulsion rates
. Ahmad et al23 has shown an effective stone expulsion rate
of more than 85% for tamsulosin group while only 55% rate for patients without tamsulosin treatment.
Studies have reported expulsion rate
of 3.8% to 12%.13-22 Our study showed expulsion rate
of 6%; 6.7% with spontaneous vaginal delivery (SVD) versus 4.3% with caesarean section although not statistically significant.
The study group showed higher stone expulsion rate
(100%) and time to expulsion (M = 10.34 days) than control.
While the expulsion rate
was higher than seen generally, it is still an effective method for most obese women.
Keep in mind that there is a somewhat higher expulsion rate
for IUDs placed in the immediate postpartum period.
of 4.7% is quite low as in another study the expulsion rate
was 9% postplacental and 37% if placed postpartum17 (fig-2).
(7) in Turkey in 2011 noted an expulsion rate
of 17.6% at 12 months with the TCu380A IUD inserted immediately following cesarean section delivery.
(24) However, even if IUD insertion is performed immediately postpartum, there is a higher expulsion rate
than when the IUD is inserted [greater than or equal to]4 weeks postpartum.
It increases the expulsion rate
and decreases the expulsion time, thereby reducing the cost and lost working days.
However, a study demonstrated that expulsion rate
with single dose of 400 mcg oral misoprostol was about 13 % , while, another study demonstrated that repeated doses of 400 mcg misoprostol can lead to increased expulsion rate
up to 70% [26, 27].
indicated that tamsulosin increases stone expulsion rate
