Local anesthesia before TRUS guided prostate biopsy: A retrospective evaluation of clinical efficacy, performance technical results and side effects on patients and image quality

Objectives: 1. To demonstrate the procedure of TRUS guided local anesthesia before performing prostate biopsy. 2. To study possible complications on patients and deterioration on image quality. Methods: We compared retrospectively 8420 patients who underwent TRUS guided prostate biopsies performed following local periprostatic anesthesia (8–15 cc Xylocaine-2% Adrenaline transrectally-years 2000–2006, group A) to 10133 patients with TRUS guided biopsies performed without local anesthesia (1994–2005, group B). We studied the technique, its effects on patient comfort and tolerance time, quality of US image, patient…
