Clean intermittent catheterization (CIC) is a cornerstone of bladder management in patients with neuro-urological and other lower urinary tract disorders. Although safer than long-term indwelling catheterization, its effectiveness depends on regular adherence, appropriate catheterization frequency, and accurate monitoring of catheterized volumes. Digital health tools may improve self-management, but dedicated applications for CIC remain limited. We developed MyBladderControl (MBC), a digital tool designed to support patients performing CIC, and conducted an early evaluation of its functionality, usability, and agreement with specialist clinical judgment.

MBC was developed through collaboration between urologists and biomedical engineers and is currently compatible with both mobile devices and computers. The application allows daily recording of catheterization number, catheterized urine volume, spontaneous voiding episodes, and adverse events. Automated alerts are generated when catheterized volumes fall outside the recommended range (<150 mL or >500 mL). Weekly reports summarize trends, highlight abnormal values and adverse events, and provide suggestions for optimizing bladder management, including possible adjustment of daily catheterization frequency according to median catheterized volume. A preliminary pilot evaluation was conducted in five CIC users, who tested the application for at least two weeks and completed a dedicated user survey. Reports generated by the app were independently reviewed by a specialist to evaluate concordance between app-generated recommendations and clinical judgment.

Five patients used the application for a median of 2 weeks, generating two weekly reports each. During the observation period, 31 alerts were recorded for catheterized volumes outside the recommended range; 30/31 alerts were due to volumes > 500 mL. An inappropriate daily catheterization frequency was observed in 80% of participants. Based on weekly median catheterized volume, the app recommended increasing daily catheterizations in 20% of patients, while no cases met criteria for reduction. All participants reported that the app was easy to use and useful in supporting their CIC routine. Specialist review showed full agreement between the app’s recommendations and clinical judgment.

A key aim of MBC was to translate clinical reasoning into an algorithm capable of supporting early modulation of catheterization frequency. The high agreement observed between app-generated recommendations and specialist assessment suggests that the algorithm can reliably reproduce an initial clinical decision-making process. In addition, the frequent detection of high catheterized volumes highlights the potential role of digital monitoring in identifying suboptimal bladder emptying habits and supporting timely behavioural correction.

MyBladderControl appears to be a feasible and user-friendly digital tool for CIC self-management. It may represent a valuable alternative to paper bladder diaries, supporting adherence, structured monitoring, and early optimization of catheterization habits. Larger studies are needed to confirm its clinical utility and long-term impact.
