Comparison of the outcome of trans-ureteral lithotripsy for uncomplicated ureteral stones with or without safety guidewire: A randomized clinical trial.

Introduction: Using a safety wire during trans-ureteral lithotripsy (TUL) might minimize ureteral injuries. Conversely, others suggest safety wire itself may increase the risk of ureteral injuries that its routine use is not mandatory in all cases. This randomized clinical trial was conducted to compare the outcome of TUL in the presence or absence of a safety guidewire.

Post-operative Analgesia in Opioid Dependent Patients: Comparison of Intravenous Morphine and Sublingual Buprenorphine.

Background: Acute and chronic pain is prevalent in patients with opioid dependence. Lack of knowledge concerning the complex relationship between pain, opioid use, and withdrawal syndrome can account for the barriers encountered for pain management. This study was designed to evaluate the efficacy of sublingual (SL) buprenorphine for post-operative analgesia, compared with intravenous (IV) morphine.
