Nocturia in female patients: Current clinical features, treatment patterns and outcomes at a tertiary referral centre

This is the authors' abstract. We don't add key points for this paper.

Objective: To report the current clinical features, treatment patterns and outcomes of female patients who were seen at a tertiary referral centre with a primary diagnosis of nocturia, and to assess the predictive factors of therapeutic management failure.Patients and methods: A retrospective chart review of all new female patients seen in a single-centre functional urology practice with the diagnosis of nocturia was performed. Up to three visits within a 12-month period from the time of presenting were reviewed. The primary endpoint was patient-reported improvement assessed at each follow-up visit and the change in the number of nocturia episodes.Results: In all, 239 female patients were included for analysis. The prevalence of nocturnal polyuria, reduced bladder capacity, and global polyuria were 75%, 40.2%, and 18.1%, respectively. Within the first two visits, 72.7% of patients had started a treatment beyond behavioural therapies. Anticholinergics were the most commonly initiated treatment (47.2% of patients). At the latest considered visit, 80 patients reported improvement in nocturia (45.5%) and there was a mean – 0.8 decrease in the number of nocturia episodes from 4 to 3.2, which was statistically significant (P < 0.001). There was no statistically significant association between any of the bladder diary findings and treatment outcomes. A smaller number of nocturia episodes was the only predictive factor of therapeutic management failure in multivariate analysis (odds ratio 0.10; P = 0.01).Conclusions: Whilst the prevalence of nocturnal polyuria in women with nocturia is high, the therapeutic management until 2016 seemed to rely mostly upon overactive bladder medications with a relatively low success rate.
