Introduction: Introduction: Prostatic gland lesions are becoming an alarming health hazard among Indian males. Early diagnosis and risk prediction are crucial for accurate treatment decisions. TRUS and MRI are effective in the diagnosis of prostatic lesions.
Aim: To assess the role of Transrectal ultrasound (TRUS) with colour doppler and Magnetic Resonance Imaging (MRI) in prostatic lesion detection with reference to TRUS guided biopsy.
Materials ad Methods: A total 100 cases with chief complaints of prostatic enlargement were included. Study participants underwent MRI, TRUS and TRUS guided biopsy. Collected data was analysed by using SPSS statistical software version 16.0. Lesion diagnostic efficacy was represented in terms of sensitivity, specificity, accuracy, Positive Predictive Value (PPV) and Negative Predictive Value (NPV).
Results: The mean age of cases was 71.53 years. 59% cases had Benign Prostatic Hyperplasia (BPH), 10% cases had prostatic abscess. Histopathological results showed 80 cases had benign and 13 cases had malignant lesions and rest had inconclusive lesions which means echotexture of the lesion was complicated to judge by the experts and such lesions was avoided for HPE. The main associated clinical symptoms were nocturia (39%), hesitancy (18%) and acute retention (14%). TRUS with colour Doppler detected 13 malignant lesions, among them 10 characterised with increased vascularity whereas in benign 2 lesions showed increased vascularity. MRI was failed to detect few nodular lesions which was confirmed by TRUS. TRUS has lesion detection sensitivity 88.2% and specificity 95.4%. MRI has lesion detection sensitivity 76.8% and specificity 99.7%.
Conclusion: MRI was sensitive than TRUS in detection of transcapsular extensions. TRUS is effective in differentiation of malignant and benign prostatic lesions whereas MRI is better in localising the lesions. TRUS with colour doppler was able to visualise vascular lesions promptly when compared to the MRI.
