Abstract
Robotic pyelolithotomy continues to gain attention as an alternative to percutaneous nephrolithotomy (PCNL) for managing complex renal stones. We performed a single-arm meta-analysis and systematically searched the English-language literature published in PubMed, Web of Science, Scopus, and Google Scholar databases up to June 2024. The risk of non-randomized bias was assessed using ROBINS-I, and the quality of the literature was assessed using MINORS (Methodological Index for Non-Randomized Studies). Merger parameters were calculated using Stata16/SE under a random-effects model. Five non-comparative single-arm studies were included in the meta-analysis. Results showed that the operative time for robotic pyelolithotomy was 168.10 min (95% CI 133.63, 202.56). The hospital stay was 2.63 days (95% CI 0.96, 4.29), and blood loss was 44.13 ml (95% CI 19.76, 68.51). The stone clearance rate was 87% (95% CI 79-93%). The incidence of minor postoperative complications (Clavien grade I-II) was 23.7% (95% CI 13.4-35.8%), and the incidence of major complications (Clavien grade ≥ III) was 7% (95% CI 0.3-20.7%).The safety and efficacy of robotic pyelolithotomy in treating complex renal stones are acceptable, but future large prospective cohort studies are needed to validate the treatment.

Abstract
Percutaneous nephrolithotomy (Labate et al.) is the standard procedure for the treatment of large (≥2cm) kidney stones. The patient can be in prone or modified supine position. The puncture is performed under fluoroscopy and/or ultrasound guidance. The stone-free rate seems to be comparable between miniaturized and standard PCNL. Procedures performed with smaller diameter instruments tend to be associated with significant lower blood loss, but longer procedure times. The limitation of the number of percutaneous tracts results in better preservation of the kidney function and lowers the risk of complications. The use of tranexamic acid during PCNL may be interesting for reducing the bleeding risk, the transfusion rate, and possibly the intervention duration. METHODOLOGY: These recommendations were developed using two methods: the Clinical Practice Recommendation (CPR) method and the ADAPTE method, depending on whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis [EAU 2022]) and their adaptability to the French context.

Abstract
Cystinuria is a rare genetic condition that is responsible for cystine stones. Besides stone recurrence, patients with cystine stones have reduced health-related quality of life, increased rates of chronic kidney disease and hypertension. Although lifestyle measures, medical therapy and close follow up are essential to reduce and monitor cystine stone recurrences, surgical intervention is frequently needed for most cystinuria patients. Shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy and active surveillance all have a role, and technological advances in endourology are vital in achieving a stone-free status and to prevent recurrences. The complexity of managing cystine stones necessitates a multidisciplinary team discussion, patient involvement and an individualised approach in a specialist centre for optimum management. Thulium fibre laser and virtual reality may have an increasing role in the future of cystine stone management.

Abstract
PURPOSE OF REVIEW To evaluate recent literature regarding the role of robotic technology in the treatment of nephrolithiasis with particular attention to complex technical procedures. RECENT FINDINGS Robotic platforms including single-port robotics have been widely adopted in urological practice for the treatment of both malignant and benign conditions and has led to an expansion of the utilization of robot-assisted surgery to tackle challenging clinical scenarios such as bladder neck reconstruction, upper urinary tract reconstruction, and more recently complex stone disease. Presently, the American Urological Association guidelines on the surgical management of stones advise against using robotic, open, or laparoscopic techniques as a first-line approach for most patients with stone disease with the exception for patients with anatomical abnormalities, large or complex stones, or patients requiring a concomitant reconstructive operation. Clinicians have demonstrated the safety and feasibility of surgical robotics in the treatment of stone disease for a variety of operations including robotic pyeloplasty, pyelolithotomy, ureterolithotomy, and surgical interventions in urinary diversions as well as novel technologies for robotic ureteroscopy and percutaneous access. Numerous clinicians have demonstrated the safety and feasibility of using robot-assisted surgery to treat nephrolithiasis, mainly in complex renal anatomy. Further research is necessary to identify the best candidates for utilization of robotics in complex stone disease, and further technological developments will continue to further advance the use of these platforms in the treatment of nephrolithiasis.

Abstract
INTRODUCTION AND OBJECTIVES We aimed to present a clinical study that compares standard and miniaturized percutaneous nephrolithotomy (PNL) effects on kidney function with scintigraphic imaging in primary kidney stone patients. MATERIALS AND METHODS One hundred four patients were included in this prospective study between May 2014 and February 2017. Eligible patients were divided into two groups miniaturized PNL (mPNL) and standard PNL (sPNL) with matched-pair analysis (1:1 scenario). Technetium-99m Dimercaptosuccinic Acid cortical scintigraphy imaging was performed before and after the operation. RESULTS There were no differences between the two groups in terms of success rate (mPNL (63.5%) vs. sPNL (71.2%), p=0.403), serum creatinine, glomerular filtration rate, split renal functions pre- and postoperatively (p≥0.05). There was no relationship between the type of operation and new scar formation (p=0.780). The rates of serious complication (grades 3 and 4 according to modified Clavien-Dindo Classification) were higher in sPNL (p=0.034). Stone burden, duration of operation, hemoglobin drop, multiple access, blood transfusion, and angioembolization were higher in patients with scarred kidneys (p<0.001, p=0.008, p=0.004, p<0.001, p=0.003, p=0.001, respectively). In multivariate analysis, only multiple access was found statistically significant for predicting new scar formation (p<0.001, OR: 24.28). CONCLUSIONS Miniaturized and standard PNL are reliable and successful operations for treating large kidney stones. No significant difference was found between the operation types regarding a decrease in renal function.

Abstract
The International Alliance of Urolithiasis (IAU) would like to release the latest guideline on percutaneous nephrolithotomy (PCNL) and to provide a clinical framework for surgeons performing PCNLs. These recommendations were collected and appraised from a systematic review and assessment of the literature covering all aspects of PCNLs from the PubMed database between January 1, 1976, and July 31, 2021. Each generated recommendation was graded using a modified GRADE methodology. The quality of the evidence was graded using a classification system modified from the Oxford Center for Evidence-Based Medicine Levels of Evidence. Forty-seven recommendations were summarized and graded, which covered the following issues, indications and contraindications, stone complexity evaluation, preoperative imaging, antibiotic strategy, management of antithrombotic therapy, anesthesia, position, puncture, tracts, dilation, lithotripsy, intraoperative evaluation of residual stones, exit strategy, postoperative imaging and stone-free status evaluation, complications. The present guideline on PCNL was the first in the IAU series of urolithiasis management guidelines. The recommendations, tips and tricks across the PCNL procedures would provide adequate guidance for urologists performing PCNLs to ensure safety and efficiency in PCNLs.

Abstract
BACKGROUND A systematic review and meta-analysis was conducted to explore the safety and efficacy of single-tract and multiple-tract percutaneous nephrolithotomy (PCNL) in complex renal calculi treatment. METHODS PubMed, Web of Science, Embase, EBSCO, and Cochrane library databases (updated November 2020) were searched for studies assessing the effect of different numbers of tracts on cases that underwent PCNL. The search strategy and study selection process were managed according to the PRISMA statement. RESULTS Five comparative studies were included in the meta-analysis. The multiple-tract PCNL group had a significantly increased total complications rate than the single-tract group (OR = 2.35, 95% CI = 1.71, 3.25; P < 0.00001) with insignificant heterogeneity (I2 = 0%, P = 0.52). Subgroup analysis showed there were different incidence of complications, mainly because the multiple-tract PCNL group was significantly associated with a higher rate of blood transfusion (OR = 2.99, 95% CI = 1.95, 4.57; P < 0.00001) with insignificant heterogeneity (I2 = 9%, P = 0.35). There were no differences in operation time (MD = 12.04, 95% CI = 6.36, 17.72; P < 0.0001) or hospitalization (MD = 0.54, 95% CI = 0.14, 0.95, p = 0.008). However, the singletract group had a higher stone-free rate (OR = 0.37, 95% CI = 0.19, 0.74; P = 0.005) with heterogeneity (I2 = 51%, P = 0.08), as stones in the single-tract group were smaller than those in the multiple-tract group. CONCLUSIONS The current research did not find that the multiple-tract group had a higher stone-free rate. Additionally, multiple-tract PCNL was associated with a higher incidence of blood transfusion and negative impact on renal function.

Abstract
PURPOSE OF REVIEW To present the latest evidence related to the impact of ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) on the renal function. RECENT FINDINGS Our review suggests that the overall renal function is not detrimentally affected by endourological interventions (URS, PCNL). This is however influenced by the preoperative renal function, presence of comorbidities such as diabetes and hypertension. For PCNL procedures, tract multiplicity, preoperative UTI, and postoperative bleeding also contribute to a decline in renal function. This review suggests that endourological interventions do not adversely affect renal function and tend to improve it in patients who do not have a poor renal function prior to the procedure. Several factors including poor preoperative renal function, diabetes, hypertension, and multiple percutaneous tracts appear to predispose patients to declining renal function after procedure, and these patients should be counseled for and followed up appropriately.

Abstract
The gold standard for urologic management of large stone disease traditionally has been percutaneous nephrolithotomy (PCNL). An alternative to PCNL is robotic pyelolithotomy (RP), which continues to gain traction. This study is a retrospective review of ten cases performed over a 2 year period presenting operative outcomes for large stone disease treated with RP. The mean and standard deviation were calculated for age, body mass index, stone volume, stone diameter, pre-operative creatinine, operative time, robot-docked time, length of stay, post-operative creatinine, and estimated blood loss. In addition, results were collected for post-operative complications and secondary procedure requirements. Complete stone clearance was successful in 9 of 10 cases. The average renal function remained stable from a pre-operative creatinine of 0.917 mg/dL to a post-operative creatinine level of 0.943 mg/dL. This case series demonstrates that robotic assisted surgery has practical application when managing large stone disease.
