[Effect of equal temperature bladder irrigation in patients with transurethral resection of prostate: A meta-analysis].

objectiveTo evaluate the effect of equal temperature bladder irrigation on bladder spasm, postoperative bleeding, vital signs and discomfort of chills in patients of transurethral resection of prostate using meta-analysis.

methodsSeveral electronic databases included Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, China Biology Medicine (CBM) were searched systematically for published randomized controlled trial about equal temperature bladder irrigation in patients with transurethral resection of prostate before November 20, 2019. Two reviewers selected independently the literature in the light of the inclusion and exclusion criteria, assessed the risk of bias by quality assessment and extracted data which were consisted of clinical efficacy indexes, such as incidence of bladder spasm, severity of bladder spasm, incidence of tube plugging, amount of bladder flushing fluid, time of bladder flushing, heart rate, systolic pressure, diastolic pressure, and incidence of chills. Data were pooled using fixed-effects model or random-effects model, and the summary effect measure was calculated by risk ratio (

resultsIn the study, 13 randomized controlled trails met the requirement with a total of 2 033 patients of transurethral resection of prostate were included, of whom 1 015 were carried out with equal temperature bladder irrigation and 1 018 with room temperature bladder irrigation. The results of meta-analysis showed that incidence of bladder spasm [

conclusionBased on current available evidence, equal temperature bladder irrigation reduced the incidence of bladder spasm and urinary blockage, relieved bladder spasm, reduced dosage and time of bladder irrigation, and hardly affected normal vital signs and increased the patient' s comfort.
