Comparative Analysis of Diagnostic Accuracy and Complication Rate of Transperineal Versus Transrectal Prostate Biopsy in Prostate Cancer Diagnosis

Abstract

Introduction: Transperineal prostate (TP) biopsy has emerged as a substantial alternative to the conventional transrectal (TR) approach for prostate sampling by its ability to sample specific areas of the prostate more effectively. The objective of this review is to conduct a comparative analysis of the current literature regarding diagnostic accuracy, complication rate and clinical outcome of transrectal vs. transperineal approaches in prostate biopsy-naïve patients and in repeated biopsy scenarios. Materials and Methods: An extensive search of the literature in PubMed, Scopus, and Web of Science was conducted between September 2010 and September 2024. We utilized a robust and comprehensive retrieval strategy including phrasing the two approaches as follows: (perineal or transperineal) and (rectal or transrectal). Conclusions: The transperineal and transrectal approaches show similar results in the detection of PCa in biopsy-naïve men, similar rates of infection, urinary retention and effectiveness managing biopsy-associated pain. However, in the rebiopsy scenario, the TP approach has demonstrated increased accuracy compared to the TR approach. This has significant implications in decision making and patient counselling.
