The Role of Transrectal Power Doppler Ultrasonography in Detection of Prostate Cancer
2021
Introduction: Prostatic cancer is the fourth most common male malignancy worldwide. It is the commonest human cancer found at autopsy in 30% of men at age of 50 and almost 90% at age 90. To decrease the mortality caused by prostate cancer much attention has given to its early detection. power Doppler imaging (PDI) appeared to increase the sensitivity and help identify appropriate sites for biopsy. Aim of This Study: The aim of this study was to determine the role of Transrectal Power Doppler ultrasonography in the diagnosis of prostate cancer. Methods: This was a cross-sectional study and was conducted in Urology Department of Bangladesh Institute of Research and Rehabilitation of Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College hospital (DMCH), Bangladesh during the period from July 2005 to June 2007. 36 patients were included in the study. Statistical analysis of the results was done by computer software devised in the statistical packages for social scientist (SPSS-10) and MS excel-16. Result: In total 36 patients Among the 36 patients, 16 cases were benign and 20 cases were malignant lesion detected by histopathological findings. In our study we found the validity of Transrectal power Doppler in detecting prostate cancer were evaluated by calculating sensitivity 90.0%, specificity 75.0%, accuracy 83.3%, positive and negative predictive values were 81.8% and 85.7% respectively. Conclusion: As the histopathological diagnosis of the present study significantly correlate with Transrectal power Doppler findings and the validity tests are almost identical as observed by other researchers of different study, it can be concluded that Transrectal power Doppler ultrasonogram is useful diagnostic modality in the discrimination of benign and malignant lesions in the prostate.
