Re: Predicting an Effective Ureteral Access Sheath Insertion: A Bicenter Prospective Study Y. Mogilevkin, M. Sofer, D. Margel, A. Greenstein and D. Lifshitz Department of Urology, Rabin Medical Center, Petah Tikva, Israel J Endourol 2014; 28: 1414e1417.
Abstract for this article http://dx.doi.org/10.1016/j.juro.2015.01.013 available at http://jurology.com/ Editorial Comment: Ureteral access sheaths are now commonly used to facilitate flexible ureteroscopic procedures. These authors identified certain factors that predict the ability to successfully insert a ureteral access sheath. I routinely perform semirigid ureteroscopy with a 7.5Fr instrument before attempting to place an access sheath. If the ureter does not readily accommodate the ureteroscope, I do not attempt to pass an access sheath, and proceed with either flexible ureteroscopy or placement of an internalized stent. I believe that this approach saves dollars and ureters. Dean G. Assimos, MD

Abstract for this article http://dx.doi.org/10.1016/j.juro.2015.01.005 available at http://jurology.com/ Editorial Comment: In this well-done randomized study of 148 patients undergoing laparoscopic cholecystectomy the use of warmed humidified CO2 for insufflation decreased postoperative pain on the day of surgery. However, the advantage was small. There was a significant difference in patient reported pain using a visual analogue scale 6 hours postoperatively (0.3 points on a 0 to 10-point scale) but no difference on postoperative day 1. There was no difference in the mean amounts of pain medication used on the day of surgery or postoperative day 1. The authors also observed no difference in the return of bowel function and a 0.2C higher intraoperative core
The use of a ureteral access sheath (UAS) may provide significant advantages, particularly, in the treatment of a large renal stone burden. However, in some patients, the passage of a UAS up the ureter is impossible. We prospectively evaluated the ab
We previously described ureteroscopy assisted retrograde nephrostomy (UARN). In UARN, it is possible to continuously visualize the dilation of the ureter from puncture to insertion of the nephroaccess sheath with minimal complication. But in the cour
Ureteral obstruction caused by malignancy is a challenging and often complicated problem for urologists. We present a novel technique of ureteric access sheath aided insertion of a Resonance metal ureteric stent in the setting of a difficult obstruct
Malignant ureteral obstruction (MUO) is an unpropitious sign that is commonly observed in patients with advanced incurable cancer. The present study aimed to evaluate predictive factors for the failure of retrograde ureteral stent insertion in the ma
