“…Many reports on sophisticated technologies in urology seem to be applicable to the pancreas as well [11,12]. In 2004, Marescaux et al first reported the use of an overlay display on a monitor for adrenalectomy [36].…”

“…However, there is an unexpectedly limited number of reports regarding the clinical use of AR-based NS for gastroenterological surgeries because the development of abdominal AR-based NS has been delayed due to problems associated with intraoperative organ deformity or the continued use of established surgical modalities. On the other hand, several sophisticated technologies in urology have been recently reported because intraoperative organ shifting or deformity of the kidney or prostate is relatively small [11,12]. The pancreas is also situated in the retroperitoneum, and therefore, we focused on the pancreas as a target organ for AR-based NS.…”

Aim: The aim of this study was to evaluate the utility of navigation surgery using augmented reality technology (AR-based NS) for pancreatectomy. Methods: The 3D reconstructed images from CT were created by segmentation. The initial registration was performed by using the optical location sensor. The reconstructed images were superimposed onto the real organs in the monitor display. Of the 19 patients who had undergone hepatobiliary and pancreatic surgery using AR-based NS, the accuracy, visualization ability, and utility of our system were assessed in five cases with pancreatectomy. Results: The position of each organ in the surface-rendering image corresponded almost to that of the actual organ. Reference to the display image allowed for safe dissection while preserving the adjacent vessels or organs. The locations of the lesions and resection line on the targeted organ were overlaid on the operating field. The initial mean registration error was improved to approximately 5 mm by our refinements. However, several problems such as registration accuracy, portability and cost still remain. Conclusion: AR-based NS contributed to accurate and effective surgical resection in pancreatectomy. The pancreas appears to be a suitable organ for further investigations. This technology is promising to improve surgical quality, training, and education.

“…Radical prostatectomy is one of the standard modalities for localized prostate cancer 2 . Robotic surgery has been accepted to improve surgical quality 3 in urological surgery, and robot‐assisted laparoscopic radical prostatectomy (RARP) has become one of the most widely used procedures due to its minimal invasiveness and comparable outcomes with conventional procedures 4,5 . Therefore, it is important to achieve satisfactory surgical outcomes of RARP without peri‐ and postoperative complications.…”

Background: This study assessed the incidence and impact of acute kidney injury (AKI) on renal prognosis in patients who underwent robot-assisted laparoscopic radical prostatectomy (RARP). Methods: Medical records of 305 patients treated with RARP were retrospectively reviewed. The patients with postoperative AKIs were dichotomized into early AKI (immediately after surgery) and late AKI (1-7 days after surgery). The impact of AKIs and their risk factors were statistically assessed. Results: Early and late AKI were observed in 143 (46.9%) and 12 (3.9%) patients, respectively. Hypertension and console time were independent risk factors for early AKI. Among the patients with preoperative eGFR ≥60 mL/min, the eGFR decline 12 months after surgery was significantly greater in patients with early AKI than that without early AKI (−6.8 vs −3.2 mL/min, P = .02). Conclusions: Approximately half of patients developed early AKI after RARP. The patients with early AKI had reduced renal function 12 months after surgery. K E Y W O R D S acute kidney injury, prostate cancer, robot-assisted laparoscopic radical prostatectomy 1 | INTRODUCTION Prostate cancer is the second leading cause of cancer-related death in men worldwide. 1 Radical prostatectomy is one of the standard modalities for localized prostate cancer. 2 Robotic surgery has been accepted to improve surgical quality 3 in urological surgery, and robot-assisted laparoscopic radical prostatectomy (RARP) has become one of the most widely used procedures due to its minimal invasiveness and comparable outcomes with conventional procedures. 4,5 Therefore, it is important to achieve satisfactory surgical outcomes of RARP without peri-and postoperative complications. Acute kidney injury (AKI) is a postoperative complication of prostatectomy that is associated with chronic kidney disease (CKD) and death. 6,7 There are several potential causes of postoperative AKI, including patient and surgical factors. 7 RARP can impair renal function due to high pneumoperitoneum pressure and an extremely steep head-down position of the patient. 8,9 Several studies report the incidence of AKI after RARP compared with that after conventional open surgery. 7,10 However, the frequency and clinical significance of AKI after RARP remains unclear. In this study, we assessed the incidence, risk factors and impact on renal prognosis of AKI observed during the very early period after surgery in patients with prostate cancer who underwent RARP. 2 | PATIENTS AND METHODS 2.1 | Patients and study design We retrospectively reviewed the medical records of 305 consecutive patients with localized prostate cancer patients who underwent

“…Today, LESS surgery is used for a wide range of urological diseases, such as adrenal tumors, renal tumors, pelvi‐ureteric junction obstruction and urachal remnant, among others . Nevertheless, LESS surgery is still considered to be an alternative option used only for selected patients because of its technical difficulty and a lack of enough evidence . Furthermore, a relatively large percentage of the literature that reports on LESS surgery originates from high‐volume centers with experienced surgeons.…”

Objective: To report on a multi-institutional series of non-robotic urological laparoendoscopic single-site surgery in Japan. Methods: Consecutive cases of laparoendoscopic single-site surgery carried out between February 2009 and December 2012 at nine academic institutions were included. We examined the surgical outcomes, including conversion and complications rates. Results: Four hundred and sixty-nine cases were included in the analysis. The most common procedure was adrenalectomy (n = 177) and the second most common procedure was radical nephrectomy (n = 143). The procedures also included nephroureterectomy (n = 40), living donor nephrectomy (n = 40), pyeloplasty (n = 30), urachal remnant excision (n = 9), simple nephrectomy (n = 7), radical prostatectomy (n = 6) and others (n = 17). The access sites included umbilicus (n = 248, 53%) and other sites (n = 221, 47%). A transperitoneal approach was used in 385 cases (82%), and retroperitoneal approach in 84 cases (18%). The median operation time of all procedures was 198 min. Conversion to reduced port surgery, conventional laparoscopy, or open surgery was noted in 27 cases (5.8%), 12 cases (2.6%), and two cases (0.4%), respectively, with an overall conversion rate of 8.7%. Intraoperative complications occurred in 10 cases (2.1%). Post-operative complications were noted in 29 cases (6.2%), including five major complications (1.1%). No mortality was recorded in this series. Conclusions: Non-robotic laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases in Japan. Furthermore, urological laparoendoscopic single-site surgery is a promising minimally invasive surgical option that is feasible for experienced urological surgeons in intermediate-volume centers as well as high-volume centers.
