Although both techniques offer acceptable diagnostic accuracy, the pain experienced during and after the procedure is an important factor influencing the choice of biopsy approach and overall patient comfort. Pain perception in prostate biopsy is multifactorial, depending on the biopsy route, the number of needle insertions, the local anesthesia protocol, and the innervation of the relevant anatomical structures. The aim of this prospective study is to compare anticipated (pre-procedural expected) and experienced (post-procedural actual) pain levels in patients undergoing transrectal versus transperineal prostate biopsy, using the Visual Analog Scale (VAS). Findings are expected to contribute to clinical decision-making regarding biopsy approach selection with a focus on patient comfort.",[63],"Prostate Cancer",[65,66,67,68,69],"prostat cancer","pain","outpatient urology","pain perception","prostate biopsy","NOT_YET_RECRUITING","2026-05-05",{"date":73,"type":74},"2026-05-11","ACTUAL",{"date":76,"type":58},"2026-05-10",{"date":78,"type":58},"2026-08-10",{"name":5,"class":6},1]
