Bladder scanning is a fast, non-invasive method of detecting the residual volume within the bladder with no risk of infection or trauma. Although highly sensitive, the post void residual volumes reported by bladder scanning is not specific for urine retention; false positive rates of up to 9% have been reported. To increase the awareness of this phenomenon we outline an illustrative case in which a BladderScan (BVI 3000, Verathon, The Netherlands) reported a post void residual volume of 494ml and urethral catheterisation was performed but no urine drained. Bedside abdominal ultrasound eventually demonstrated that the patient had ascites. The BladderScan had misinterpreted this intra-abdominal fluid as urine within the bladder. We therefore recommend that formal diagnostic imaging of the abdomen and pelvis is performed if there is any discrepancy between the urine volume reported by bladder scanning and that measured by urinary catheterization.
