ABSTRACT

Objective: To determine the sensitivity and specificity of the resident physician’s digital rectal examination to detect prostate cancer and the incidence of aggression due PSA at the Hospital Regional “Lic. Adolfo Lopez Mateos” ISSSTE, in patients undergoing transrectal prostate biopsy.
Design: Cross-sectional, analytical, descriptive study. 377 patients who underwent PSA, RT and TRBP from 2017 to 2020 were included, these was made by residents of the second year of Urology.
Results: The average age was 66.2 years, the median PSA 10.45ng/mL, and the average prostate volume was 71.1cc, we used transrectal ultrasound. The sensitivity and specificity of digital rectal examination in patients with PSA of 4-9.9ng/mL was 27% and 90.4% respectively, in patients with PSA of 10- 19.9ng/mL, it was 49.2% and 85.9% and in patients with PSA greater than 20ng/mL was 73.8% and 73.1%. Limitations of the study: Rectal examination skills of the resident physician, is in training and developing skills, including detecting alterations in the digital rectal examination.
Originality: According to our search, we did not find data on the sensitivity and specificity in our country of digital rectal examination by the resident physician in a teaching hospital. So it is a good contribution to know this information when we are as resident doctors in training.
Conclusions: In our study, we observed that increasing the PSA increased the sensitivity of the RT, thus increasing the chances of obtaining a positive RHP for malignancy.
