Introduction: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is known to increase risk for calcium oxalate nephrolithiasis due to hyperoxaluria; however, nephrolithiasis rates after laparoscopic sleeve gastrectomy (LSG) are not well described. Our objective was to determine the rate of nephrolithiasis after LRYGB versus LSG.
Methods: The electronic medical records of patients who underwent LRYGB or LSG between 2001 and 2017 were retrospectively reviewed.
Surface plasmon resonance (SPR) biosensors have enabled a wide range of applications in which researchers can monitor biomolecular interactions in real time. Owing to the fact that SPR can provide affinity and kinetic data, unique features in applications ranging from protein-peptide interaction analysis to cellular ligation experiments have been demonstrated. Although SPR has historically been limited by its throughput, new methods are emerging that allow for the simultaneous analysis of many thousands of interactions.

Methods: Seven patients with urethral rupture injuries (two anterior and five posterior urethral injuries) were treated.
Objectives: To evaluate and compare the efficacy of caudal and local nerve blocks in preventing pain following outpatient pediatric urologic surgery.
Methods: Seventy-seven boys undergoing outpatient urologic surgery were randomized into one of three groups: general anesthesia alone, general anesthesia and caudal nerve block, or general anesthesia and local nerve block. Pain scores, frequency of medication, and total dosage of medication were recorded in the immediate postoperative period.
