Abstract: Diagnosis and management of prostatic cancer (PCa) cases mainly rely on levels of prostatic-
specific antigen (PSA) levels. In the majority of cases, rising of PCa is usually responsible for
elevated PSA. However, a wide variety of prostatic abnormalities, such as benign prostatic hyperplasia
and infection or inflammation of the prostatic glands, may also impact prostate levels. Due to
the low specificity and sensitivity of the PSA test, elevated PSA levels can lead to unnecessary prostate
biopsies or surgical interventions, constituting this diagnostic modality a controversial screening
test. Therefore, the discovery of new non-invasive biomarkers, such as urinary miRNAs, could shed
light on the optimal management and follow-up of patients with prostatic lesions. This study aims to
evaluate the utility of urinary miRNAs as a new PCa prognostic biomarker, discovering its current
limitations and proposing methods to overwhelm current challenges.
