  Obesity is a known risk factor for recurrent nephrolithiasis and it can be challenging to provide safe surgical intervention in the super obese population. Despite high weight limits on surgical beds, these often do not take into account positioning the patient on the end of the bed for dorsal lithotomy, which can risk an unsteady bed. In addition, depending on patient habitus the leg stirrups may not accommodate. There is limited literature that discusses the technical approach for positioning super obese patients in dorsal lithotomy when the weight limit approaches or exceeds the capacity of equipment available. In this article, we present a modified positioning technique to improve bed stability, which also provides an alternative if the patient's legs are not supported by available leg stirrups. From our experience, this modified dorsal lithotomy positioning for ureteroscopy is feasible and safe in patients with super obesity. Surgical intervention on this population requires appropriate planning and teamwork to ensure safe positioning.

  Appropriate perioperative management of antithrombotic medications is critical; for every patient, the risk of bleeding must be balanced against individual risk of thrombosis. There has been a rapid influx of new antithrombotic therapies in the past 5 years, yet there is a lack of clear and concise guidelines on the management of anticoagulant and antiplatelet therapy during urologic surgery. Here we describe our approach to perioperative antithrombotic counseling, including the timing of stopping and restarting these medications. These practice guidelines have been developed in consultation with the Vascular Medicine service at our institution as well as after a review of current literature, and apply to common urologic procedures. Many cases are complex and require medical consultation or a multidisciplinary approach to management. We believe that by presenting our systematic method of antithrombotic management, including when to involve other discplines, we can increase knowledge and comfort amongst urologists in managing these medications in the perioperative period.

  Infection of artificial urinary sphincters or inflatable penile prostheses is one of the most devastating complications after prosthetic surgery and can have a significant impact on a quality of life. Patients undergoing revision surgery with or without device replacement may have increased risk for infection when compared to initial primary surgery. As such, surgeons may utilize traditional culture results to direct antimicrobial therapy for these patients. Unfortunately, culture results can be inconclusive in up to one-third of the time even in the setting of active device infection. Next-generation sequencing (NGS) of DNA is an emerging technology capable of sequencing entire bacterial genomes and has the potential to identify microbial composition in explanted devices. Herein, we describe our institutional experience on NGS utilization in patients with genitourinary prostheses. We also highlight our methods and techniques to inform readers on the potential practices that can enhance the utility and diagnostic yield of this new and upcoming technology.

• How I Do It: The Optilume drug-coated balloon for urethral strictures

  Urethral stricture disease can be difficult to treat and stricture recurrence is common. The management of stricture disease has evolved and urethroplasty can achieve a high rate of lasting urethral patency. Nevertheless, endoscopic treatments still seem to have sub-optimal outcomes with high stricture recurrence rates. The Optilume drug-coated balloon represents a step forward in the endoscopic management of urethral strictures. The drug-coated balloon may offer an intermediate step prior to repeated dilations, urethrostomies, or urethroplasty. This treatment modality is a promising alternative to current endoscopic management and an option for patients that are poor surgical candidates or decline urethroplasty.

  The da Vinci single port (SP) robotic system (Intuitive Surgical, Sunnyvale, CA, USA) is a recently approved robotic platform designed with several modifications to the previously available multi-port robotic systems. This article describes the technique performed utilizing the SP robotic system for radical robotic-assisted laparoscopic prostatectomy (RALP) with or without bilateral pelvic lymph node dissection from a single institution. In this report we describe our step-by-step approach, technical modifications from the multi-port technique and initial results for performing single port robotic-assisted laparoscopic prostatectomy (SP-RALP). We describe our initial experience and technique with the SP robotic system consisting of 23 consecutive patients who underwent SP-RALP between December 2018 and May 2019. The median patient age was 62 years with approximately half of the patients undergoing pelvic lymphadenectomy. The median operative time was 236 minutes, median estimated blood loss was 50 mL and median length of hospital stay was 1 day. No unplanned port placements occurred and no conversions to open surgery occurred. We demonstrate the safety and feasibility of performing a transperitoneal prostatectomy with either a posterior or anterior approach.
