INTRODUCTION: Post Void Residual Volume (PVRV) is a known risk factor for urinary infection, incontinence and renal insufficiency. Disposing for the condition is high age, immobility, constipation, neurological and metabolic disease. The objectives of this study was to determine the prevalence and to examine risk factors for high PVRV among geriatric patients. MATERIAL AND METHODS: In a prospective study 100 consecutive patients admitted to a geriatric ward had an ultrasound bladder scan (UB) performed three times during the first two days of stay. The following background parameters were registered: age, gender, Mini Mental-State Examination (MMSE), modified Barthel score, bacteriuria, urinary incontinence and constipation. Exclusion criteria: urinary catheter, incapability of giving informed consent. Patients could only be included once. RESULTS: A total of 142 patients were screened, among whom 100 were included (81 women and 19 men). The mean age was 83.9 years (range: 65-101 years). Background parameters: constipation 29%, urinary incontinence 41%, bacteriuria 37%. Barthel (maximum score 100): 12% score < 26, 25% score 26-49, 41% score 50-79 and 20% score > 79. MMSE: 12% < 15.37% 15-24 and 39% > 24. UB results: A total of 48 patients had a PVRV < 100 ml in all three UB, and 14 patients had a PVRV > 150 ml in all three UB. In all, 38 patients had a PVRV between 100 and 150 ml or diverging results. Barthel score (p = 0.03) and bacteriuria (p = 0.04) varied significantly between patients with a PVRV > 150 ml and a PVRV < 100 ml. CONCLUSION: PVRV is a common condition in geriatric populations and is positively correlated with bacteriuria and low functional performance. It is feasible to implement UB as a screening procedure in geriatric wards.
