Recent work has demonstrated that it is possible to distinguish specific stone-forming phenotypes by endoscopic patterns of papillary appearance alone.^1-4 These variable expressions are likely to have clinical significance; yet, the ability to pursue such research efforts remains limited by the lack of a standardized system to describe these findings. Herein, we describe a novel grading system designed to standardize and simplify the description of renal papillary appearance in stone formers at the time of endoscopy. <b><i>Materials and Methods:</i></b> Since 1999, 342 patients have been prospectively enrolled and given consent to be part of an NIH funded project studying the pathogenesis of stone formation at a single institution (Methodist Hospital, Indiana University Health). Patients have been treated and studied using both percutaneous and retrograde ureteroscopic approaches. Digital scopes are utilized when feasible along with fluoroscopy to map the affected renal unit(s), and stones are removed and analyzed individually when possible.⁵ <b><i>Results:</i></b> Four recurring abnormal papillary features were identified based upon the collective knowledge and expertise of the primary research team. Each variable was then quantitated based on the severity in appearance. Three features believed to be associated with papillary injury include ductal plugging, pitting, and loss of papillary contour. Ductal plugging is evident as either suburothelial deposits of yellow mineral or as dilated ducts of Bellini, presumably left behind after a plug has passed. These two subfeatures are considered the same for the purposes of grading. Pitting reflects crater-like erosion of the papillary surface. Loss of contour reflects global depression of the papilla relative to the surrounding tissue. Upon papillary inspection, each papilla receives a numerical grade from 0 to 2 for each of these measured domains. The three scores are then added together to create a sum total score regarding the degree of papillary injury ranging from 0 to 6. The fourth feature, the amount of Randall's plaque, is evident as white deposits along the papillary surface. It is not known to cause papillary injury⁶ and, as such, is designated with an alphabetical subscore (a-c) rather than a number. Each papilla then receives a final unique score incorporating both the sum numerical and alphabetical grade. Reference examples are shown in the accompanying video. <b><i>Conclusions:</i></b> The creation of a standardized system to describe the papillary appearance in stone formers has considerable clinical and academic utility. On a clinical level, it could be applied as a tool to document intraoperative findings and determine changes in papillary appearance over time in recurrent stone formers.

While robotic partial nephrectomy (RPN) has been widely adopted as a minimally invasive option, one concern is the long-term effects of prolonged warm ischemia time (WIT) on renal function and cardiac health. Multiple technological and procedural advancements have been proposed to limit WIT, but most are technically difficult to perform. Argon beam coagulation (ABC) can be used to coagulate the base of a tumor fossa before performing formal renorrhaphy. This may allow for improved hemostasis during deep hemostatic suturing, thus allowing for earlier hilar unclamping. We report our initial experience with ABC during RPN in a pig model, to test the feasibility of this technology for RPN. Materials and Methods: Six Yorkshire pigs underwent bilateral RPN using the Da Vinci Si Surgical System (Intuitive, Sunnyvale, CA).

Quality of life (QoL) scores were assessed before RALP, after urethral catheter removal, and at the first month of RALP.

Yao, Jianrong Huang, Shulin Guo, Zuofeng Peng","doi":"10.1089/VID.2015.0036","DOIUrl":"https://doi.org/10.1089/VID.2015.0036","url":null,"abstract":"Abstract Introduction: Flexible ureteroscopy (URS) is becoming a first-line therapy for many patients with renal and ureteral calculi rapidly.1 Current commonly used medical infusion devices can only monitor the infusion flow and infusion pressure, but not the renal pelvic pressure (RPP).2,3 We sought to invent a novel technique of suctioning flexible URS with an intelligent control of RPP. Materials and Methods: We performed flexible URSs for patients with the help of a self-designed intelligent system, including an irrigation and suctioning platform and a transparent ureteral access sheath (UAS) with a pressure-sensitive tip, which can precisely regulate the infusion flow and control the vacuum suctioning by computerized real-time recording and monitoring of RPP through pressure feedback, ensuring a stable RPP. The outer body diameter of the UAS was 15F; the diameter of the working channel was 11.55F; and the length of the UAS was 20 to 45 cm. On the platform, RPP control value was set at −2 mm Hg, RPP warning value was set at 20 mm Hg, and RPP limit value was set at 30 mm Hg. Intraoperatively, Holmium laser was used to powderize the stone at 0.8 J/pulse with a frequency of 20 pulses/second (Lumenis, fiber diameter 200 μm). In the process of powderizing lithotripsy using the laser, the scope body was moved back and forth slightly in an uninterrupted manner in the sheath, with a distance of about 2 to 3 mm, to facilitate small gravel particles inside the sheath gap to be sucked out automatically. Gravel particles, larger than sheath gap but less than UAS in diameter, were sucked out by withdrawing the scope intermittently without a need of stone basketing. We retrospectively reviewed 51 patients with renal or ureteral calculus (55 renal units, 9 ureteral calculi), who received the flexible URS from November 2014 to March 2015. Results: We were able to perform all the procedures with clear operative visualization. The mean stone size was 16.1±3.9 mm. The mean operative time was 22.3±16.4 minutes. The stone-free rate on postoperative day 30 was 93.8% (60/64) by the kidney, ureter, and bladder radiograph. No patient had a sepsis. Conclusions: Flexible URS with the help of our intelligent system is technically feasible, safe, and efficacious for treating upper urinary tract calculi with the advantages of breaking stones at high efficacy and low complication rates because of its automatic control of RPP.
