Abstract

BACKGROUND

Male lower urinary tract symptoms (LUTS) increase with age and negatively impact quality of life. Conservative treatment with physiotherapeutic approaches and changes in lifestyle are often neglected. App-based therapeutics may have some benefits for patients with LUTS.

METHODS

In this prospective, two-center, single-blinded trial, men with LUTS were randomly assigned 1:1 to either an intervention group with access to an app-based therapeutic in addition to their usual medical care or a control group receiving only their usual medical care. The primary end point was symptom improvement (change from baseline to week 12) as measured by the International Prostate Symptom Score (IPSS; range 0 to 35, with higher scores indicating more severe symptoms; minimal clinically important difference of 3). Secondary end points included symptom improvement, as measured by the Overactive Bladder Questionnaire - Short Form part 1 (OAB-q-SF symptom bother, six items; range 6 to 36, transformed to a scale from 0 to 100, with higher scores indicating more severe symptoms), and health-related quality of life (HRQOL), as measured with the OAB-q-SF part 2 (13 items; range 13 to 78, transformed to a scale from 0 to 100 with higher scores indicating better HRQOL).

RESULTS

A total of 237 patients were randomly assigned, with seven participants subsequently dropping out. The mean age (± standard deviation [SD]) was 58.4 (12.3) years; 46.4% had benign prostatic enlargement alone, 22.4% had…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 237 participants or records.
