“…In line with the ease provided by GPS-based route/traffic planning in daily life, insight into the ideal route could also improve needle placement. An assumption that relates to statements made by England et al [ 39 ]. We, however, observed that virtual needle-navigation reduced the needle movement fluency for both groups (see Fig.…”

Purpose Navigational strategies create a scenario whereby percutaneous needle-based interventions of the liver can be guided using both pre-interventional 3D imaging datasets and dynamic interventional ultrasound (US). To score how such technologies impact the needle placement process, we performed kinematic analysis on different user groups. Methods Using a custom biopsy phantom, three consecutive exercises were performed by both novices and experts (n = 26). The exercise came in three options: (1) US-guidance, (2) US-guidance with pre-interventional image-registration (US + Reg) and (3) US-guidance with pre-interventional image-registration and needle-navigation (US + Reg + Nav). The traveled paths of the needle were digitized in 3D. Using custom software algorithms, kinematic metrics were extracted and related to dexterity, decision making indices to obtain overall performance scores (PS). Results Kinematic analysis helped quantifying the visual assessment of the needle trajectories. Compared to US-guidance, novices yielded most improvements using Reg (PSavg(US) = 0.43 vs. PSavg(US+Reg) = 0.57 vs. PSavg(US+Reg+Nav) = 0.51). Interestingly, the expert group yielded a reversed trend (PSavg(US) = 0.71 vs PSavg(US+Reg) = 0.58 vs PSavg(US+Reg+Nav) = 0.59). Conclusion Digitizing the movement trajectory allowed us to objectively assess the impact of needle-navigation strategies on percutaneous procedures. In particular, our findings suggest that these advanced technologies have a positive impact on the kinematics derived performance of novices.

최근에 우연히 발견되는 신장 종괴의 증가와 국소 치료, 표적 치료와 같은 신장암 치료 선택지의 다양화, 그리고 신장 이식의 보편화에 따라서 신장의 조직 검사가 증가하고 있는 추세이다. 그러나 신장은 피부부터 장기까지의 거리가 멀어 조직 검사의 난이도가 높은 편으로 특히 초심자들은 신장의 조직 검사를 부담스럽게 여길 수 있다. 이 종설에서 우리는 신장 조직 검사의 적응증과 기술적인 고려 사항들, 진단 정확도, 그리고 합병증에 대해서 알아보겠다. 특히 실전적인 팁들을 다양한 증례들과 함께 알아보며 다양한 상황에서도 안전하고 효과적으로 조직 검사를 시행할 수 있게 도움이 되고자 한다.

Purpose of reviewThe puncture technique and site of the puncture can impact the clinical outcome and the development of postoperative adverse events following percutaneous nephrolithotomy (PCNL). The aim of the current review was to discuss the available puncture guidance approaches and outline the potential role of the recently introduced electromagnetic-guided method. Recent findingsThe puncture and PCNL tract establishment is usually performed using fluoroscopic or ultrasound guidance or a combination of two approaches. Electromagnetic-guided puncture is one of the most recent advancements of technology. The puncture navigation to the renal collecting system is available after placing a special wire with an electromagnetic tracking sensor into the desired calyx through the flexible ureterorenoscope. The available experimental and clinical studies have shown a high first puncture rate, decreased median time for obtaining a puncture, and shorter learning curves for beginners. SummaryFluoroscopic and ultrasound guidance are the main approaches used by urologists. However, these modalities require a steep learning curve, approximately 60 cases for reaching competency. The initial data on electromagnetic navigation have shown the feasibility and potential promising outcomes of this novel approach. New studies are required to investigate its potential implementation opportunities in the daily practice of urologists.
