Quality improvement project: Optimal post-void residual urine volume to guide intermittent catheterization in hospitalised older persons with acute retention of urine.

Introduction: There is no consensus on the optimal postvoid residual urine volume (PVRU) as a cut-off value prior to performing intermittent catheterisation (IMC). We did a quality improvement project to determine a reasonable PVRU for use in the hospital setting.

Materials And Methods: All patients admitted to the five geriatric medicine wards in a geriatric department over a 5- month period who developed acute retention of urine were included in the project.
