Bladder Diary Feasibility and Reliability in Neurogenic Lower Urinary Tract Dysfunction Patients.

Objectives: Bladder diary (BD) is an important tool to understand patients' lower urinary tract symptoms. But few data exist on adult neurogenic lower urinary tract dysfunction (ANLUTD) patients. The aim was to assess in real-life practice the feasibility, reliability and influencing factors of BD completion in patients with ANLUTD.

Materials and methods: All patients with ANLUTD who had a first neuro-urologic consultation between January 2022 and April 2023 were included. No patients underwent intermittent self-catheterization. We collected demographic data, validated questionnaires about symptoms and quality of life, the presence and analysis of the 3-day BD. BD was classified as feasible if patients returned it nonempty and was deemed reliable if patients had completed at least 2 consecutive days, if it did not have an intake-output imbalance, and if it were consistent with the USP questionnaire. We investigated influencing factors of feasibility and reliability with a general linear regression.

Results: One hundred and nighty-nine patients were included (mean age 56 ± 14; 111 (55.7%) women). Eighty-four (42.2%) had demyelinating disease, 55 (27.6%) Parkinson's disease, 51 (25.6%) neuro-genetic disorder and 7 (4.5%) spinal cord injury or cauda equina syndrome. BD were classified as feasible for 128 (64%) patients and 45 (40.5%) were deemed reliable. In a generalized linear model, no factor was associated with BD feasibility or reliability.

Conclusions: In a ANLUTD population, the BD is a feasible tool, but its interpretation should be met with caution due to its limited reliability. No factor was associated with the feasibility or reliability of the BD.
