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.
