Background: Lower urinary tract symptom (LUTS) is a common condition in older men. In accordance with the Dutch College of General Practitioners Guideline “Micturition symptoms in men”, the diagnosis can be made based on a patient’s medical history and a physical examination. GPs lack additional tools in primary care to assess the residual urine volume. A residual volume usually requires a referral to a urologist. We hypothesized that the IPSS screening questionnaire score (measuring the severity of symptoms) might be related to patients’ residual urine volume. The research objective was to examine the relation between the IPSS score and the residual urine volume.
Methods: In a cross-sectional study, we analysed patients’ IPSS and residual urine volume. Men aged over 50 with LUTS who consulted Dutch primary-care physicians were included. The interventions comprised an IPSS screening and a bladder scan. Data regarding the patients’ residual volume, total IPSS score, single IPSS score, IPSS storage score, and IPSS voiding score were recorded and analysed. We used odds ratios to describe the relation between the IPSS categories associated with the presence of a normal or abnormal (above 100 cc and above 200 cc) residual urine volume.
Results: A total of 126 patients were included in this study. Patients with higher scores on the overall IPSS, separate IPSS, IPSS storage and IPSS voiding showed no higher odds ratios of having an abnormal residual volume, neither above 100 mL or 200 mL.
Conclusion: We did not find a relation between the IPSS core to an abnormal residual urine volume in men aged over 50 with LUTS consulting primary-care physicians.
Trial Registration: This study has been approved by the Central Committee on Research Involving Human Subjects for the Arnhem-Nijmegen Region and is registered with ToetsingOnline under ID number 29822.091.10.
