Pressure-flow urodynamics is the investigation of choice in the diagnosis of BOO. In our routine practice, especially in developing countries we depend on lesser invasive methods including uroflowmetry, prostate volume, and Post void residual urine (PVR). There are many non-invasive methods for diagnosing BOO, one among them is measuring Detrusor Wall Thickness (DWT) using ultrasonography. The objective of our study is to compare the accuracy of Detrusor Wall Thickness (DWT) to other non invasive tests and Pressure Flow Study (as a reference) in the assessment of BOO in men presenting with LUTS. METHODS: This prospective study included 86 patients who were neurologically free with Bladder outlet obstruction. Men over 50 years were studied for BOO using detrusor wall thickness along with tests such as uroflowmetry, prostate volume and Post-Void Residual (PVR) which was then compared to pressure flow study as the gold standard. All patients were submitted to a history, clinical examination, urine analysis and culture and blood chemistry. RESULTS: The DWT was ranging from 0.6 mm to 8.2 mm. Among the 86 patients studied 36 were diagnosed as BOO with DWT≥2 mm. Based on the pressure-flow test, 40 patients had BOO. Detrusor wall thickness had the highest specificity (95.6%), positive predictive value (94.7%) and accuracy (93.02%) as a non-invasive test in diagnosing BOO. CONCLUSIONS: Detrusor wall thickness has a better specificity, accuracy and positive predictive value compared to other tests. Measuring DWT as an additional parameter along with other non-invasive tests can greatly increase the accuracy of diagnosing BOO. Further studies are required to validate the findings of this study before this technique can be recommended as a primary diagnostic tool for BOO.
