Enuresis: clinical evolution of patients attended at specialized unit of paediatric urology

To analyse the clinical evolution, the therapeutic strategies and the characteristics of the patients presenting enuresis attended at our outpatient clinic.

Retrospective study of patients <14 years old(yo) diagnosed of enuresis attended at our outpatient clinic (2011-2019) and completed their follow-up (remission or aged 15). Urotherapy was offered to all patients as initial management. The therapeutic strategies were classified as: first line (desmopressin or clock alarm), second line (desmo-pressin+alarm) and third line(anticholinergics). The remission rate during follow-up, the number of consultations needed until remission and the treatments used were calculated. Statistical tests used:Kaplan-Meier, actuarial survival. Multivariate analysis:Cox regression.Statistical significance:p<0.05.

Data were collected from 125 patients (mean age: 8.6±2.45yo). Family history of enuresis was present in 38.9%. The mean follow-up was 2.37±1.55yo and the average number of consultations was 7.54±5.06. The remission rate (RE) was 84%(n=105), with a median remission interval:2.66 years (2.34-2.991[95%CI]). The average number of treatments required for remission was 2.74±1.27. RE with urotherapy alone was 20%(n=25); RE with first line:19.3%(n=17) and second line:16.7(n=11). In the remaining patients, a RE of 78.18%(n=43) was achieved by adding an anticholinergic. Patients aged > 8.7 years at the beginning of the follow-up required less time to achieve remission (p=.025). These patients had a higher RE (hazard ratio 1.15 (1.05-1.25))(p=.004). No other variables were significant.

Staged therapeutic strategies are necessary to achieve remission. Only 25% remitted with urotherapy as single treatment. RE are higher when patients are >8.7 yo once they initiate their follow up.
