The Urological Association of Asia, consisting of 25 member associations and one affiliated member since its foundation in 1990, has planned to develop Asian guidelines for all urological fields. The field of stone diseases is the third of its guideline projects. Because of the different climates, and social, economic and ethnic environments, the clinical practice for urinary stone diseases widely varies among the Asian countries. The committee members of the Urological Association of Asia on the clinical guidelines for urinary stone disease carried out a surveillance study to better understand the diversity of the treatment strategy among different regions and subsequent systematic literature review through PubMed and MEDLINE database between 1966 and 2017. Levels of evidence and grades of recommendation for each management were decided according to the relevant strategy. Each clinical question and answer were thoroughly reviewed and discussed by all committee members and their colleagues, with suggestions from expert representatives of the American Urological Association and European Association of Urology. However, we focused on the pragmatic care of patients and our own evidence throughout Asia, which included recent surgical trends, such as miniaturized percutaneous nephrolithotomy and endoscopic combined intrarenal surgery. This guideline covers all fields of stone diseases, from etiology to recurrence prevention. Here, we present a short summary of the first version of the guideline – consisting 43 clinical questions – and overview its key practical issues.

Background— Percutaneous puncture is the most critical step in percutaneous nephrolithotomy (PCNL). In this study, we aimed to investigate the clinical value of a navigation system based on deep learning and mixed reality for the treatment of kidney stones with percutaneous nephrolithotomy, and to improve its theoretical basis for the treatment of kidney stones. Methods— The data of 136 patients with kidney stones from October 2021 to December 2023 were retrospectively analyzed. All patients underwent percutaneous nephrolithotomy, and were categorized into a control group (Group 1) and a surgical navigation group (Group 2) according to puncture positioning method. Preoperative computed tomography (CT) was performed in both groups. In group 1, the puncture location was determined according to CT. Percutaneous nephrolithotomy was performed with navigation system in group 2. The baseline information and procedural characteristics of both groups were compared. Results— Percutaneous nephrolithotomy was successfully performed in both groups. No significant difference was found in the baseline date between the two groups. In group 2, real-time ultrasound images could be accurately matched with CT images with the aid of navigation system. The success rate of single puncture, puncture time, and decrease in hemoglobin were significantly improved in group 2 compared to group 1. (p < 0.05). Conclusions— The application of navigation system based on deep learning and mixed reality in percutaneous nephrolithotomy for kidney stones allows for real-time intraoperative navigation, with acceptable accuracy and safety. Most importantly, this technique is easily mastered, particularly by novice surgeons in the field of percutaneous nephrolithotomy. Trial registration This study was retrospectively registered in Chinese Clinical Trial Registry, registration number: ChiCTR2400079909, date of registration: 2024-1-16.

“…Currently, the combined use of preoperative computed tomography (CT) and intraoperative ultrasound-guided localization significantly improves the safety and efficiency of PCNL. [ 6 , 7 ] On the basis of our experience on PCNL, a prospectively randomized controlled study was designed to investigate the role of pre-designed route on computer tomography urography (CTU) in the ultrasound-guided PCNL. In CTU group, a proper puncturing route was designed on CTU, and the approximate puncturing area was marked on the back, followed by ultrasound-guided PCNL.…”

This study aimed to assess the role of pre-designed route on computer tomography urography (CTU) in the ultrasound-guided percutaneous nephrolithotomy (PCNL) for renal calculus.From August 2013 to May 2016, a total of 100 patients diagnosed with complex renal calculus in our hospital were randomly divided into CTU group and control group (without CTU assistance). CTU was used to design a rational route for puncturing in CTU group. Ultrasound was used in both groups to establish a working trace in the operation areas. Patients’ perioperative parameters and postoperative complications were recorded.All operations were successfully performed, without transferring to open surgery. Time of channel establishment in CTU group (6.5 ± 4.3 minutes) was shorter than the control group (10.0 ± 6.7 minutes) (P = .002). In addition, there was shorter operation time, lower rates of blood transfusion, secondary operation, and less establishing channels. The incidence of postoperative complications including residual stones, sepsis, severe hemorrhage, and perirenal hematoma was lower in CTU group than in control group.Pre-designing puncture route on CTU images would improve the puncturing accuracy, lessen establishing channels as well as improve the security in the ultrasound-guided PCNL for complex renal calculus, but at the cost of increased radiation exposure.
