Relationship between obstetric history and recurrent urinary infections

Abstract

Urinary tract infections affect more than 50% of women. 25% derive from recurrent UTI (RUTI). It is not known the relationship between obstetric history and RUTI occurrence. Investigate the relationship between obstetric events and RUTI. Multicenter observational retrospective study. Groups: G.RUTI (n = 294): women with RUTI; G.NON.RUTI (n = 126): women without RUTI (treated and cured of renal cancer). Descriptive statistics, ANOVA analysis of variance (with Scheffe's test for normal samples and Kruskal-Wallis for other distributions), Fisher's exact test, Pearson and Spearman correlation studies, and multivariate analysis multiple regression were used. Mean age 61.04 years (19-92), G.RUTI: 56.77 years SD 4.46 (19-85). G.NON.RUTI: 71 years SD 6.73 (25-92) (p = 0.0001). Obstetric history: Nulliparous G.RUTI: 20 (3.4%) G.NON.RUTI: 90 (71.42%) p 0.0001; Eutocic G.RUTI: 416 (70.74%) G.NON.RUTI: 30 (23.8%) p 0.0001. Dystocic G.RUTI: 58 (9.86%) G.NON.RUTI: 56 (44.44%) p 0.0001. G.RUTI abortion: 102 (17.34%) G.NON.RUTI: 30 (23.8%) p 0.1381. Hysterectomy without adnexectomy G.RUTI: 100 (17%) G.NON.RUTI: 18 (14.28%) p 0.5640. Hysterectomy with adnexectomy G.RUTI: 100 (17%) G.NON.RUTI: 66 (52.28%) p 0.0001. Nulliparity, dystocic delivery, and hysterectomy with adnexectomy are more frequent in women without RUTI, while eutocic births are more associated with RUTI. The most prevalent gynaecological-obstetric history in women with RUTI is eutocic delivery associated with a good health state.
