Bladder training video not inferior to urotherapy for bladder/bowel dysfunction
The bladder training video appears to be as effective as standard urotherapy in reducing bladder/bowel symptoms in children, according to a recent study.
“The video allows families to have free access to independently review bladder training concepts as often as necessary,” researchers said.
To assess the effectiveness of an animated bladder training video, a noninferiority randomized, controlled trial was performed involving patients (aged 5 to 10 years) who scored >11 on the bladder/bowel Vancouver questionnaire. Children with vesicoureteral reflux, neuropathic bladder, learning disabilities, recent urotherapy or primary nocturnal enuresis were excluded from analysis.
Researchers randomized patients to receive either standard urotherapy or watch a bladder training video in clinic using centralized blocked randomization schemes. Then, they assessed bladder/bowel symptoms at baseline and 3-month follow-up by intent-to-treat analysis.
A sample size of 150 patients ensured a 3.5 difference in mean symptomology scores between the groups, which was accepted as the noninferiority margin.
Of the enrolled patients, a total of 143 (95 percent) completed the trial, five (4 percent) were lost to follow-up and 2 (1 percent) withdrew from the study. Baseline characteristics between the two groups were similar.
Baseline mean symptomology score was for 19.9 for the bladder training video and 19.7 for standard urotherapy. The mean symptomology scores at 3 months were reduced to 14.1 and 13.8 for the bladder training video and standard urotherapy, respectively (p=0.54). The mean difference was 0.6 (95 percent CI, ‒1.4 to ‒2.6).
“The upper 95 percent CI limit of 2.6 did not exceed the preset 3.5 noninferiority margin,” according to researchers.
