Molecular detection of the COVID-19 genome in prostatic tissue of patients with previous infection

COVID-19 infection has been linked to worsening or de novo lower urinary tract symptoms and transient serum prostate-specific antigen rise in patients with benign prostatic hyperplasia. This pilot study aimed to examine prostatic tissue for evidence for direct involvement with the COVID-19 (SARS-CoV-2) infection. Fourteen patients with previous documented COVID-19 infection who underwent prostate enucleation had their prostate specimens examined for COVID-19 RNA. The specimens were examined using a SARS-CoV-2 test, an in vitro diagnostic test based on reverse transcription polymerase chain reaction technology that analyses the presence of RNA for the SARS-CoV-2 strain. Among the 14 patients, COVID infection was severe in three, mild in seven, and asymptomatic in four patients. The COVID-19 genome was successfully identified in the prostate specimen of a single patient. Although this patient had mild COVID-19 infection, he had positive COVID tests for 40 days after the initial infection. Identification of the COVID-19 genome in prostate tissue is a further step toward better understanding its effect on the genitourinary tract. This study's findings provide some explanation for the proposed association with lower urinary tract symptoms and rise in serum prostate-specific antigen levels. Larger studies are needed to further investigate this association.
