Pre-emptive tramadol could reduce pain after ureteroscopic lithotripsy.

Purpose: Optimal analgesia in ambulatory urology patients still remains a challenge. The aim of this study was to examine if the pre-emptive use of intravenous tramadol can reduce pain after ureteroscopic lithotripsy in patients diagnosed with unilateral ureteral stones.

Materials And Methods: This prospective pilot cohort study included 74 patients diagnosed with unilateral ureteral stones who underwent ureteroscopic lithotripsy under general anesthesia in the Urology Clinic at the Clinical Center of Serbia from March to June 2012.

Epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.

Introduction: Inflammation plays a key role in the development of benign prostatic hyperplasia. Prostaglandin E2 (PGE2) is an important inflammation factor found in enlarged prostatic tissue that can be the main cause of inflammatory pain. The aim of this study was to investigate whether epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.
