How specific are patient-specific simulations? Analyzing the accuracy of 3D-printing and modeling to create patient-specific rehearsals for complex urological procedures.

Purpose: In the field of urology, 3D printing and modeling are now regularly utilized to enhance pre-operative planning, surgical training, patient-specific rehearsals (PSR), and patient education and counseling. Widespread accessibility and affordability of such technologies necessitates development of quality control measures to confirm the anatomical accuracy of these tools. Herein, we present three methods utilized to evaluate the anatomical accuracy of hydrogel PSR, developed using 3D printing and molding for pre-operative surgical rehearsals, of robotic-assisted partial nephrectomy (RAPN) and percutaneous nephrolithotomy (PCNL).

Application of IRIS Three-Dimensional Anatomical Models As Preoperative Surgical Planning Tools in the Management of Localized Renal Masses.

The use of volume-rendered images is gaining popularity in the surgical planning for complex procedures. IRIS™ is an interactive software that delivers three-dimensional (3D) virtual anatomical models. We aimed to evaluate the preoperative clinical utility of IRIS for patients with ≤T2 localized renal tumors who underwent either partial nephrectomy (PN) or radical nephrectomy (RN).

Oncological and functional outcomes in patients over 70 years of age treated with robotic radical prostatectomy: a propensity-matched analysis.

Purpose: The aim of this study was to report on the safety (complications) and efficacy (oncological and functional outcomes) of robot-assisted radical prostatectomy (RARP), performed at our institution, in patients aged over 70.

Patients And Methods: Review of our prospectively collected database [Cancer Information Systems (CAISIS)] identified two hundred and fifteen (215) patients, aged > 70, who underwent RARP for localized prostate cancer between July 2003 and August 2017. A propensity score-matched analysis, with multiple covariates, was performed to stratify the patients into Age ≤ 70 and Age > 70 comparison groups.

Role of 3D printing in surgical education for robotic urology procedures.

During the past 5 years, the body of literature surrounding the utilization of three-dimensional (3D) printing in the field of urology has grown exponentially. Incentivized by work hour restrictions, patient safety initiatives, and inspired by technical advances in biomaterials and rapid printing strategies, this emerging, and fascinating area of research has begun to make headway into clinical practice. However, concerns about cost, limited understanding of the technical processes involved, and lack of its potential uses remain barriers to its widespread adoption.

Robot-Assisted Simple Prostatectomy: Illustration of a Simplified Extraperitoneal Transcapsular Technique.

Robot-assisted simple prostatectomy (RASP) performed with the extraperitoneal (EP) technique (RASP-EP) minimizes the risk of bowel injury, particularly when bowel adhesions may be expected to be prominent, by negating the need to be in the transperitoneal space. However, there is a perception of its technical difficulty owing to the limited space that can be expanded within the space of Retzius. We aimed to describe, in the accompanying video, the step-by-step approach for a technically proficient procedure.

Accelerated Skills Acquisition Protocol (ASAP) in optimizing robotic surgical simulation training: a prospective randomized study.

Purpose: To assess the efficacy of an accelerated proficiency-based training protocol in robotic simulation practice in delivering durable proficiency compared to conventional training methods.

Methods: Novice medical students (n = 16) were randomized into either the accelerated skills acquisition protocol (ASAP) or conventional training protocol (CTP). Subjects were trained to proficiency on the da Vinci Skills Simulator (dVSS) by an expert trainer.

Robotic management of genitourinary injuries from obstetric and gynaecological operations: a multi-institutional report of outcomes.

Objective: To evaluate the utility of robotic repair of injuries to the ureter or bladder from obstetrical and gynaecological (OBGYN) surgery

Patients And Methods: A retrospective review of all patients from four different high-volume institutions between 2002 and 2013 that had a robot-assisted (RA) repair by a urologist after an OBGYN genitourinary injury.

Results: Of the 43 OBGYN operations, 34 were hysterectomies: 10 open, 10 RA, nine vaginally, and five pure laparoscopic. Nine patients had alternative OBGYN operations: three caesarean sections, three oophorectomies (one open, two laparoscopic), one RA colpopexy, one open pelvic cervical cerclage with mesh and one RA removal of an invasive endometrioma.
