Introduction: The Vienna nomogram was developed to better identify the adequate number of prostatic cores that should be taken during transrectal prostatic biopsy for better detection of prostatic tumors, depending on the patient's age and the prostatic volume.
Aim of study: To compare the use of the Vienna nomogram in comparison to the standard 12-core transrectal ultrasound-guided biopsy of the prostate regarding the overall detection rate of cancer and complication rate.
Subjects and Methods: 100 patients were eligible for the study and randomized into two equal groups: group (A) who had core number determination using Vienna nomogram and group (B) who had (12) core TRUS prostatic biopsy.
Results: The rate of detection of PCa in the Vietnam nomogram group vs. the 12 core TRUS groups was 15/50 (30%) vs. 14/50 (28%), respectively. The statistical difference was insignificant. There was a statistically significant percentage of hematuria in group A, with a p-value of 0.04. The hematuria was self-limited, and regarding other complications, there wasn't any statistically significant difference between the two study groups.
Conclusions: Using the Vienna nomogram for TRUS biopsy core number determination is a safe and efficient technique for the diagnosis of prostate cancer.
