RESUMO
Introduction: The gold standard for diagnosing bladderoutlet obstruction is pressure flow study but it is associatedwith side effects of high cost, invasiveness, infection, limitedavailability. So non invasive diagnostic tests becomes a goodoption. The diagnostic accuracy of these non invasive tests,however, remains uncertain. So this study was conductedto know the role of non invasive diagnostic tests likeInternational prostate symptom score (IPSS), Uroflowmetry(UFR), prostate volume, bladder wall thickness, post voidresidual urine in symptomatic patients with BPH in theirevaluation and in the planning of management.Material and methods: The present study included 108 malepatients above 50 years suffering from symptomatic BPH whoattended urology OPD at SVIMS, Tirupati. IPSS, Urinaryflow rates, bladder wall thickness, prostate volume, post voidresidual urine and urodynamic study have been recorded inthese patients at the time of enrollment into study.Results: One hundred and eight men between 50 – 79 years ofage with mean age of 62.4 years participated in this study. Allthe patients were divided into two groups as either obstructedor un obstructed based on Abraham – Griffith numbercalculated from the urodynamic study. Bladder wall thickness,Q max, Post void residual urine and prostate volume allhad statistically significant values between obstructed andun obstructed patients. However, there was no statisticalsignificant differences between age, IPSS in both the groupsConclusion: This study shows that in a subset of patientswith BPH with predefined inclusion and exclusion criteria,it should be possible to define obstruction with simple noninvasive parameters, without using invasive pressure flowstudy
