The aim of this paper was to evaluate the current technology and designs of flexible ureterorenoscopes. We will review contemporary fiberoptic and digital ureteroscopes, including a discussion on ureteroscope damage and repair, and lastly present the projected future of flexible ureterorenoscopy. Ureterorenoscopy has evolved dramatically over the past several decades, which has led to landscape reshaping of stone disease treatment and upper tract pathology. Advancements in tip control, miniaturization of scopes, introduction of a digital chip on the tip, disposable devices to augment surgery, surgical experience/familiarity and most recently single use scopes are all independent factors that have increased flexible ureterorenoscopy adoption and success...

BACKGROUND: Open posterior spinal procedures involve extensive soft tissue disruption, increased hospital length of stay, and disfiguring scars. Our aim was to demonstrate the feasibility of using robotic-assistance for minimally invasive exposure of the posterolateral spine with and without carbon dioxide (CO2 ) insufflation. METHODS: Sheep specimens underwent minimally invasive subperiosteal dissection of the spine during three trials. The da Vinci S Surgical system was used for access with and without working space support via CO2 insufflation...

Robot-assisted gastrectomy has been reported to be a safe alternative to both conventional laparoscopy and the open approach for treating early gastric carcinoma. Currently, there are a limited number of published reports on this technique in the literature. We assessed the current status of robotic and laparoscopic surgery in the treatment of gastric cancer and compared the operative outcomes, learning curves, and oncological outcome of the two approaches. Robotic gastrectomy offers benefits that include increased ease of performing D2 lymph node dissection and reduced blood loss compared with laparoscopic gastrectomy...

Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes...

In recent years, tremendous progress has been made in surgical practice for example with Minimally Invasive Surgery (MIS). To overcome challenges coming from deported eye-to-hand manipulation, robotic and computer-assisted systems have been developed. Having real-time knowledge of the pose of surgical tools with respect to the surgical camera and underlying anatomy is a key ingredient for such systems. In this paper, we present a review of the literature dealing with vision-based and marker-less surgical tool detection...

Morbidity and mortality associated with increasingly radical doses of chemoradiotherapy have led many to question the current standard of care in head and neck cancer. Recently, surgeons have developed minimally invasive, transoral techniques which have demonstrated excellent survival and favourable functional outcomes. Transoral robotic surgery (TORS) is the most recent, cutting edge in the evolution of transoral techniques; TORS allows surgeons unprecedented access to and visualisation of the upper aerodigestive tract...

The lack of haptic feedback in roboticsassisted surgery can result in tissue damage or accidental tool-tissue hits. This paper focuses on exploring the effect of haptic feedback via direct force reflection and visual presentation of force magnitude on performance during robotics-assisted minimally invasive surgery (RAMIS) suturing. For this purpose, a haptics-enabled dual-arm master-slave teleoperation system capable of measuring tool-tissue interaction forces in all 7 Degrees-of-Freedom (DOFs) was used. Two suturing tasks, tissue puncturing and knottightening, were chosen to assess user skills when suturing on phantom tissue...

Recent advances in the surgical treatment of early stage non-small cell lung cancer (NSCLC) have focused heavily on making procedures less invasive, less radical, and better tolerated. Advances in accuracy and increased utilization of cross-sectional imaging allows for diagnosis of smaller and more indolent tumors and preinvasive lesions. Similar to advanced disease, early-stage treatment is now being tailored to individual patients and their tumors. Sublobar resections are gaining acceptance as an oncologically equivalent approach to lobectomy in well-selected stage I patients...

INTRODUCTION: Minimally invasive laparoscopic and robotic techniques for ventral hernia repair have evolved to achieve the benefits and minimize the limitations of both the open Rives-Stoppa sublay mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair. By combining the principles of a retromuscular repair with the benefits of a minimally invasive approach, these techniques attempt to decrease recurrence, increase functionality, exclude mesh from the viscera, limit infection and wound complications, and minimize pain...

Minimally invasive surgical approaches in transplantation are gaining increasing interest, and many centers are reporting their, mainly laparoscopic, experiences. Robotic surgery (RS) has some hypothetical advantages over traditional laparoscopy, and has been successfully applied, although infrequently to organ transplantation. Our goal was to review and critique the publications reporting RS use in organ transplantation. Most of the RS experience has been with living renal donor organ procurement and, to a lesser extent, with RS procedures in the transplant recipient...

Purpose Diuretic renography (DRG) is commonly used to diagnose ureteropelvic junction obstruction (UPJO) and to evaluate the success of surgical repair (pyeloplasty). Duration, frequency and interpretation of renographic follow-ups are still under dispute. Methods We retrospectively reviewed 94 consecutive patients diagnosed with UPJO who underwent a minimally invasive, robotically assisted laparoscopic pyeloplasty at our institution between 01/2009 and 09/2015. DRG was carried out preoperatively and again routinely 4-6 weeks postoperatively the day after stent removal (early DRG)...

There is a small subset of patients who have undergone endoscopic thoracic sympathectomy for hyperhidrosis or facial blushing who are dissatisfied and would wish reversal. Compensatory sweating is the most common side effect that causes a person to regret surgery. Treatment options are limited and usually not effective in patients with severe side effects from sympathectomy. Nerve graft interposition has been proven to be effective in experimental models and small clinical series. Da Vinci robotic nerve graft reconstruction with interposition graft and direct suturing of nerve and high magnification dissection most closely mirrors standard nerve reconstruction principles when done as a minimally invasive procedure...

Mitral valve dysfunction can seriously impair patients' lives and may require valve repair or replacement. Surgery can be performed using techniques including sternotomy; right thoracotomy with or without robot assistance; and the totally endoscopic robotic technique, which requires percutaneous techniques, femoral cannulation, and endovascular aortic cross-clamping. The totally endoscopic robotic technique has been facilitated by minimally invasive surgical techniques, the evolution of endoscopic techniques, and the development of surgical robots...
