To re-evaluated the clinic
efficacy of ureteroscopic
lithotripsy (URS) and extracorporeal
shock wave lithotripsy (ESWL) on
ureteral calculi with Cochrane systematic reviews in this
paper. We searched clinical randomized controlled trials and prospective controlled trials in databases such as Cochrane
library,
Medline, Springer, Elsevier
Science Direct,
PubMed. Pooled estimate of
risk ratios (RRs), standard mean difference (SMD) with 95%
confidence intervals (CIs) were used as
measure of effect sizes. Summary effect estimates were also stratified by
sample size, study design and study region. The overall effect sizes were derived using a random-effects model or fixed-effects model when appreciated, and
meta-analysis were conducted with
software RewMan 5.0. The
meta-analysis suggested that there were significant differences of post-
treatment stone free rate, repeat
treatment rate,
patients'
satisfaction,
incidence of
postoperative complications, operation
time and
hospital stays between ESWL
treatment cases and URS
treatment cases. But in the
sample sizes analysis, there were no significant differences of the post-
treatment stone free rate and repeat
treatment rate when the
sample sizes were less than 100. Compared to the ureteroscopic
lithotripsy treatment, extracorporeal
shock wave lithotripsy treatment provided a significantly lower post-
treatment stone free rate, but it also obviously brought out less
postoperative complications, shorter operation
time and
hospital stays.(AU)
