Estimation of prostate size by trans-rectal ultrasound and its correlation with DRE and endoscopic grading

Abstract

Aim: Digital rectal examination (DRE) grading and the grade of prostatomegaly on cystoscopy are routinely used in clinical practice, but its correlation to prostate volume is understudied. This study was done to assess the correlation of DRE and endoscopic grading with the prostate volume on trans-rectal ultrasound (TRUS). Materials and Methods: This study was carried out in 101 eligible patients with prostatomegaly. Each patient was evaluated for three parameters, prostate volume by TRUS examination, DRE and endoscopic grading on cystoscopy. Pearson correlation coefficient was calculated to find the correlation between variables, p<0.05 was taken to be statistically significant. Data were analyzed using the Epi Info (TM) 7.2.2.2. Results: Significant positive correlation (p<0.001) was found between TRUS Volume and DRE grading (Pearson Correlation=0.945) and TRUS volume and Endoscopic grading (Pearson Correlation=0.949). Both the grading were also significantly positively correlated (Pearson Correlation=0.989, p<0.001). Conclusion: Our attempt for correlating the digital rectal grading and endoscopic grading with prostate volume is satisfactorily validated in the clinical setting. These grades are sufficient to provide a rough estimation of the prostate volume and to classify patients with prostatomegaly.

Clinical Manifestations of Ultrasonic Virtual Reality in the Diagnosis and Treatment of Cardiovascular Diseases

“…Cardiovascular function parameters are an important way to detect cardiovascular diseases. The detection is relatively accurate, but the risk is high, so it is only suitable for severely ill people and cannot be widely used in medical treatment [ 16 , 17 ]. There are many methods to detect cardiovascular function clinically, including CT scan examination, electrocardiogram detection, echocardiography, and nuclear magnetic resonance; these methods can effectively detect cardiovascular function to effectively control cardiovascular disease, but these detection instruments are not only cumbersome to operate but also costly and are not suitable for general household use.…”
