- Abstract
Introduction: To evaluate the relationship of UEBW with severity of post-voiding residual urine in a man with LUTS. Methods: UEBW was determined non-invasively with portative ultrasound device; BladderScan BVM 6500 (Diagnostic Ultrasound, Bothell, WA). In a total of 77 men aged 50 years or more evaluated with IPSS, uroflowmetry and UEBW. These men were divided into 2 groups (residual urine <100ml and residual urine > 100 ml). 52 men (aged 67.2 ± 7.9, median 66.5) were in group I and 21 men (aged 68.3± 9.3, median 68.0) were in group II. Results: Comparison of these two groups, maximal flow rate was 14.7± 6.9, median 14.0 and 9.1± 5.9, median 7.0 ml/sec; P<0.00. Average flow rate was 7.5± 4.3, median 7.0 and 4.4± 2.9, median 3.0 ml/sec, P<0.00. IPSS was13.5 ± 7.7 and 15.9 ± 7.6, P>0.05. UEBW was 47.4±.7.8 g; median 46.5 and 48.1± 11.8g; median 45.0; P>0.05. Conclusions: On the contrary, uroflowmetry shows significant difference between these two groups. Possibly, the causes of post-voiding residual urine are complicated and therefore, influence the result UEBW. The result is different from some reports published previously. From our preliminary studies, we concluded that UEBW is not related to severity of post-voiding residual urine and pressure-flow studies is still necessary for the patients with post-voiding residual urine in order to differentiate bladder outlet obstruction from neurogenic bladder.
