The effect of adding Montelukast to oxybutynin on daily urination in children with pollakiuria: a randomized clinical trial.

PURPOSE: Pollakiuria is defined as a change in the pattern of daily urination. Students have mentioned wetting their pants at school as the third tragic event after the death of a parent or going blind. In this study, the effect of adding Montelukast to oxybutynin on the improvement of urinary symptoms of patients with pollakiuria was studied.

MATERIALS AND METHODS: This study was a pilot clinical trial in which children with pollakiuria aged 3-18 years old were included. These children were randomly divided into two groups of intervention (Montelukast plus oxybutynin) and the control group (only oxybutynin). At the beginning and the end of the study (after 14 days), mothers were asked about the frequency of daily urination. Finally, the gathered data were compared between two groups.

RESULTS: In the present study, 64 patients were examined in two intervention and control groups (32 in each group). The results revealed that although significant changes were observed in both groups before and after intervention, the average changes in the intervention group were significantly higher (p = 0.014).

CONCLUSION: The results of this study showed that adding montelukast to oxybutynin has a significant decrease in frequency of daily urination in patients with pollakiuria, although further studies are recommended in this area.
