Objectives
To provide a comprehensive overview of the current status of the field of robotic systems for urological surgery and discuss future perspectives.
Materials and Methods
A non‐systematic ...literature review was performed using PubMed/Medline search electronic engines. Existing patents for robotic devices were researched using the Google search engine. Findings were also critically analysed taking into account the personal experience of the authors.
Results
The relevant patents for the first generation of the da Vinci platform will expire in 2019. New robotic systems are coming onto the stage. These can be classified according to type of console, arrangement of robotic arms, handles and instruments, and other specific features (haptic feedback, eye‐tracking). The Telelap ALF‐X robot uses an open console with eye‐tracking, laparoscopy‐like handles with haptic feedback, and arms mounted on separate carts; first clinical trials with this system were reported in 2016. The Medtronic robot provides an open console using three‐dimensional high‐definition video technology and three arms. The Avatera robot features a closed console with microscope‐like oculars, four arms arranged on one cart, and 5‐mm instruments with six degrees of freedom. The REVO‐I consists of an open console and a four‐arm arrangement on one cart; the first experiments with this system were published in 2016. Medicaroid uses a semi‐open console and three robot arms attached to the operating table. Clinical trials of the SP 1098‐platform using the da Vinci Xi for console‐based single‐port surgery were reported in 2015. The SPORT robot has been tested in animal experiments for single‐port surgery. The SurgiBot represents a bedside solution for single‐port surgery providing flexible tube‐guided instruments. The Avicenna Roboflex has been developed for robotic flexible ureteroscopy, with promising early clinical results.
Conclusions
Several console‐based robots for laparoscopic multi‐ and single‐port surgery are expected to come to market within the next 5 years. Future developments in the field of robotic surgery are likely to focus on the specific features of robotic arms, instruments, console, and video technology. The high technical standards of four da Vinci generations have set a high bar for upcoming devices. Ultimately, the implementation of these upcoming systems will depend on their clinical applicability and costs. How these technical developments will facilitate surgery and whether their use will translate into better outcomes for our patients remains to be determined.
The coronavirus disease 2019 (COVID-19) pandemic is unlike anything seen before by modern science-based medicine. Health systems across the world are struggling to manage it. Added to this struggle ...are the effects of social confinement and isolation. This brings into question whether the latest guidelines are relevant in this crisis. We aim to support urologists in this difficult situation by providing tools that can facilitate decision making, and to minimise the impact and risks for both patients and health professionals delivering urological care, whenever possible. We hope that the revised recommendations will assist urologist surgeons across the globe to guide the management of urological conditions during the current COVID-19 pandemic.
The coronavirus disease 2019 (COVID-19) pandemic is unlike anything seen before by modern science-based medicine. As a scientific society, the European Association of Urology, via the guidelines, section offices, and the European Urology family of journals, we believe that it is important that we try to support urologists in this difficult situation. We aim to do this by providing tools that can facilitate decision making with the goal to minimise the impact and risks for both patients and health professionals delivering urological care, whenever possible, although it is clear that it is not always possible to mitigate them entirely. We hope that these revised recommendations will fill an important urological practice void and assist urologist surgeons across the globe as they do their very best to deal with the crisis of our generation.
Abstract Background An improved armamentarium has had a significant impact on the emerging role of flexible ureteroscopy (FURS) for the management of nephrolithiasis; however, FURS still represents a ...challenging technique. Objective To examine a robotic device designed for FURS for its impact on ergonomics and outcome of the procedure based on the IDEAL (idea, development, evaluation, assessment, long-term study) framework. Design, setting, and participants Roboflex Avicenna consists of a surgeon's console and a manipulator for the flexible ureterorenoscope. Following experimental evaluation of the prototype (IDEAL stage 1) and receipt of ethical approval, seven surgeons treated 81 patients (mean age: 42 yr range: 6–68) with renal calculi (mean volume: 1296 ± 544 mm3 range: 432–3100 mm3 ) in an observational study (IDEAL stage 2). Surgical procedure Robotic FURS was performed with the Roboflex Avicenna robotic device. Outcome measurements and statistical analysis Numerical data were analysed with the Mann-Whitney test, and categorical variables were analysed using the chi-square test or Fisher exact test. P values <0.05 were considered statistically significant. Results and limitations Mean robot docking time was 59.6 ± 45 s. Mean operative time was 74 min (range: 40–182). Mean fragmentation speed was 29.1 ± 6.1 mm3 /min. Ergonomics based on a validated questionnaire showed significant advantage for robotic FURS (total score: 5.6 vs 31.3; p < 0.01). A 10/12F-access sheath was used in 72 patients. Two cases required secondary FURS, one because of malfunction of the flexible digital ureteroscope and another because of larger residual fragments. In the remaining 79 cases, complete stone disintegration was accomplished. Conclusions Roboflex Avicenna provides a suitable and safe platform for robotic FURS with significant improvement of ergonomics. Future studies should evaluate its impact on the clinical outcome of FURS. Patient summary Robotic flexible ureteroscopy (FURS) was performed with the Roboflex Avicenna robotic device. Results showed that Roboflex Avicenna provides a suitable and safe platform for robotic FURS with significant improvement of ergonomics.
Artificial intelligence (AI) is the field of computer science that aims to build smart devices performing tasks that currently require human intelligence. Through machine learning (ML), the deep ...learning (DL) model is teaching computers to learn by example, something that human beings are doing naturally. AI is revolutionizing healthcare. Digital pathology is becoming highly assisted by AI to help researchers in analyzing larger data sets and providing faster and more accurate diagnoses of prostate cancer lesions. When applied to diagnostic imaging, AI has shown excellent accuracy in the detection of prostate lesions as well as in the prediction of patient outcomes in terms of survival and treatment response. The enormous quantity of data coming from the prostate tumor genome requires fast, reliable and accurate computing power provided by machine learning algorithms. Radiotherapy is an essential part of the treatment of prostate cancer and it is often difficult to predict its toxicity for the patients. Artificial intelligence could have a future potential role in predicting how a patient will react to the therapy side effects. These technologies could provide doctors with better insights on how to plan radiotherapy treatment. The extension of the capabilities of surgical robots for more autonomous tasks will allow them to use information from the surgical field, recognize issues and implement the proper actions without the need for human intervention.
Abstract Context Laser treatment of benign prostatic obstruction (BPO) has become more prevalent in recent years. Although multiple surgical approaches exist, there is confusion about laser–tissue ...interaction, especially in terms of physical aspects and with respect to the optimal treatment modality. Objective To compare available laser systems with respect to physical fundamentals and to discuss the similarities and differences among introduced laser devices. Evidence acquisition The paper is based on the second expert meeting on the laser treatment of BPO organised by the European Association of Urology Section of Uro-Technology. A systematic literature search was also carried out to cover the topic of laser treatment of BPO extensively. Evidence synthesis The principles of generation of laser radiation, laser fibre construction, the types of energy emission, and laser–tissue interaction are discussed in detail for the laser systems used in the treatment of BPO. The most relevant laser systems are compared and their physical properties discussed in depth. Conclusions Laser treatment of BPO is gaining widespread acceptance. Detailed knowledge of the physical principles allows the surgeon to discriminate between available laser systems and their possible pitfalls to guarantee high safety levels for the patient.
Background
Extracorporeal shock wave lithotripsy represents one option for the non-surgical management of Peyronie’s disease. Despite promising results, several questions are still pending. We want ...to present the long-term results of a retrospective study using high-energy extracorporeal shock wave lithotripsy.
Material and methods
We evaluated retrospectively 110 patients treated between 1996 and 2020 at the Department of Urology, SLK Kliniken Heilbronn for chronic phase Peyronie’s disease using two electromagnetic lithotripters (Siemens Lithostar Plus Overhead Module, Siemens Lithoskop) applying high-energy shock waves under local anesthesia and sonographic or fluoroscopic control. A standardized questionnaire focused on the change in pain, curvature, sexual function and the need of penile surgery.
Results
In 85 of the 110 patients (mean age 54 years) we had sufficient data for evaluation. The median follow-up was 228 (6–288) months. There were no significant complications. Pain reduction was achieved in all patients, 65 (76%) patients were free of pain. Improvement of penile curvature was achieved in 43 patients (51%) ranging from 25% improvement (deflected angle < 30°) to 95% (angle 30–60°). 59 patients (69%) reported problems with sexual intercourse, 40 of those (68%) reported improvement. Only 9 (10.5%) patients underwent surgical correction. We did not observe any significant differences between both electromagnetic devices with stable long-term results.
Conclusions
High-energy shock wave therapy delivered by two standard electromagnetic lithotripters is safe and efficient providing stable long-term results. In cases with significant plaque formation, the concept of high-energy ESWT should be considered in future studies.
Abstract Context The introduction of new lithotripters has increased problems associated with shock wave application. Recent studies concerning mechanisms of stone disintegration, shock wave ...focusing, coupling, and application have appeared that may address some of these problems. Objective To present a consensus with respect to the physics and techniques used by urologists, physicists, and representatives of European lithotripter companies. Evidence acquisition We reviewed recent literature (PubMed, Embase, Medline) that focused on the physics of shock waves, theories of stone disintegration, and studies on optimising shock wave application. In addition, we used relevant information from a consensus meeting of the German Society of Shock Wave Lithotripsy. Evidence synthesis Besides established mechanisms describing initial fragmentation (tear and shear forces, spallation, cavitation, quasi-static squeezing), the model of dynamic squeezing offers new insight in stone comminution. Manufacturers have modified sources to either enlarge the focal zone or offer different focal sizes. The efficacy of extracorporeal shock wave lithotripsy (ESWL) can be increased by lowering the pulse rate to 60–80 shock waves/min and by ramping the shock wave energy. With the water cushion, the quality of coupling has become a critical factor that depends on the amount, viscosity, and temperature of the gel. Fluoroscopy time can be reduced by automated localisation or the use of optical and acoustic tracking systems. There is a trend towards larger focal zones and lower shock wave pressures. Conclusions New theories for stone disintegration favour the use of shock wave sources with larger focal zones. Use of slower pulse rates, ramping strategies, and adequate coupling of the shock wave head can significantly increase the efficacy and safety of ESWL.
