The different timing of removing indwelling urinary catheter for puerperas who use patient controlled analgesia after cesarean section: a meta-analysis

Abstract

Objective To assess the effects of removing indwelling urinary catheter at different timing on urinary retention puerper as who use patient controlled analgesia(PCA)after cesarean section. Methods Taking the database of PubMed, Embase, Cochrane Library, Medline, CNKI, CBM, VIP and Wanfang before December 2016 as the retrieval sources; collecting the results of randomized controlled trial(RCT) about the incidence of postpartum urinary retention with PCA which removing the ureteral catheter after 24 hours, 36 hours, and 48 hours respectively; using RevMan 5.3 software for statistical analysis. Results A total of 10 study papers were collected, included involving 1 639 maternity patients. The incidence of urinary retention with ureteral catheter removal after 24 hours was higher than after 36 hours, the difference was statistically significant (RR=4.95, 95%CI 3.67-6.68, P<0.01); the incidence of urinary retention with ureteral catheter removal after 36 hours was higher than after 48 hours, the difference was statistically significant (RR=3.00, 95%CI 1.66-5.41, P<0.01); the incidence of urinary retention with ureteral catheter removal after 24 hours was higher than after 48 hours the difference was statistically significant (RR=11.84, 95%CI 7.84-18.66, P<0.01). Conclusion In order to prevent the occurrence of urinary retention, the more appropriate timing to remove the urinary catheter after cesarean section with PCA is after 48 hours Key words: Cesarean section; Analgesia, patient-controlled; Urinary catheters; Urinary retention; Meta-analysis
