OBJECTIVES: To determine the reliability of the postvoiding volume measurement of two US methods. METHODS: A comparative study of transabdominal and portable ultrasound (Bladderscan model) in the selected and non-selected modes was conducted in 96 patients (54 males, 42 females; mean age 59.92 yrs). RESULTS: Conventional US had the lowest failure rate (26.99%). The failure rate was 41.66% for the selected mode and 57.77% for the non-selected mode. The main failure of transabdominal ultrasound was a defect failure. The non-selected mode had a defect and excess failure. The selected mode had a defect failure. There was and inverse relationship between the residual volume and the failure rate of the non-selected mode of the Bladderscan model. The failure rate was higher for males vs females in the non-selected mode. The possible sources of failure are analyzed. CONCLUSION: Conventional transabdominal ultrasound is currently the most reliable ultrasound method.
