Abstract
OBJECTIVES To establish a three-dimensional visualization model of percutaneous nephrolithotomy, apply it to guiding intraoperative puncture in a mixed reality environment, and evaluate its accuracy and clinical value. METHODS Patients with percutaneous nephrolithotomy indications were prospectively divided into three-dimensional group and control group with a ratio of 1:2. For patients in three-dimensional group, positioning markers were pasted on the skin and enhanced computed tomography scanning was performed in the prone position. Holographic three-dimensional models were made and puncture routes were planned before operation. During the operation, the three-dimensional model was displayed through HoloLens glass and visually registered with the patient's body. Puncture of the target renal calyx was performed under three-dimensional-image guiding and ultrasonic monitoring. Patients in the control group underwent routine percutaneous nephrolithotomy in the prone position under the monitoring of B-ultrasound. Deviation distance of the kidney, puncture time, puncture attempts, channel coincidence rate, stone clearance rate, and postoperative complications were assessed. RESULTS Twenty-one and 40 patients were enrolled in three-dimensional and control group, respectively. For three-dimensional group, the average deviation between virtual and real kidney was 3.1 ± 2.9 mm. All punctures were performed according to preoperative planning. Compared with the control group, the three-dimensional group had shorter puncture time (8.9 ± 3.3 vs 14.5 ± 6.1 min, P < 0.001), fewer puncture attempts (1.4 ± 0.6 vs 2.2 ± 1.5, P = 0.009), and might also have a better performance in stone clearance rate (90.5% vs 72.5%, P = 0.19) and postoperative complications (P = 0.074). CONCLUSIONS The percutaneous nephrolithotomy three-dimensional model manifested acceptable accuracy and good value for guiding puncture in a mixed reality environment.

World J Radiol 2021; 13:354-370. [PMID: 34904050 PMCID: PMC8637607 DOI: 10.4329/wjr.v13.i11.354] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 08/26/2021] [Accepted: 10/27/2021] [Indexed: 02/06/2023] Open
Abstract
Radiology education and training is of paramount clinical importance given the prominence of medical imaging utilization in effective clinical practice. The incorporation of basic radiology in the medical curriculum has continued to evolve, focusing on teaching image interpretation skills, the appropriate ordering of radiological investigations, judicious use of ionizing radiation, and providing exposure to interventional radiology. Advancements in radiology have been driven by the digital revolution, which has, in turn, had a positive impact on radiology education and training. Upon the advent of the corona virus disease 2019 (COVID-19) pandemic, many training institutions and hospitals adhered to directives which advised rescheduling of non-urgent outpatient appointments. This inevitably impacted the workflow of the radiology department, which resulted in the reduction of clinical in-person case reviews and consultations, as well as in-person teaching sessions. Several medical schools and research centers completely suspended face-to-face academic activity. This led to challenges for medical teachers to complete the radiology syllabus while ensuring that teaching activities continued safely and effectively. As a result, online teaching platforms have virtually replaced didactic face-to-face lectures. Radiology educators also sought other strategies to incorporate interactive teaching sessions while adopting the e-learning approach, as they were cognizant of the limitations that this may have on students’ clinical expertise. Migration to online methods to review live cases, journal clubs, simulation-based training, clinical interaction, and radiology examination protocolling are a few examples of successfully addressing the limitations in reduced clinical exposure. In this review paper, we discuss (1) The impact of the COVID-19 pandemic on radiology education, training, and practice; (2) Challenges and strategies involved in delivering online radiology education for undergraduates and postgraduates during the COVID-19 pandemic; and (3) Difference between the implementation of radiology education during the COVID-19 pandemic and pre-COVID-19 era.
