Four urologic trainees (with similar little previous PCNL experience) will be recruited for the simulation. Two end points will be assessed: Number of attempts to achieve desired renal puncture and total fluoroscopy time.\n\nThis simulation via 12 balls phantom device will involve fluoroscopic screening of calyx and successful puncture by urologic trainees under consultant supervision. Trainees will have 30 attempts of free hand puncture and 30 attempts using the ANT-X. The trainee will only move on to patient's renal puncture once they are able to achieve more than 80% of satisfactory renal puncture on simulator.\n\nFor human renal puncture, we will aim for 60 cases of PCNL, 30 to be done using ANT-X puncture and 30 using traditional free hand puncture performed by 4 urologic trainees (15 cases per urologic trainee)."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subjects willing to sign informed consent form before initiation of any study specific procedures.\n* Subjects diagnosed with kidney stones and planned for prone PCNL.\n* Male/ non- pregnant female subjects between 18-75 years (both inclusive) of age at the time of informed consent.\n* Subjects with renal stones of ≥1 cm or not managed by other stone treatments (e.g. shock wave lithotripsy, ureteroscopy).\n* Serum creatinine of \\< 1.2 mg/dl.\n\nExclusion Criteria:\n\n* Subjects with bleeding disorders.\n* Recent infection of the kidney or urinary tract which leads to pus accumulation in the kidney, i.e., Pyonephrosis.\n* Subjects not able to have prone positions for surgical procedure due to comorbid conditions.\n* Renal stones \\< 1 cm and can managed by another technique.\n* Patients with moderate to severe renal failure.\n* Patients with congenital urinary tract anomalies.\n* Patients on anticoagulation or antiplatelet therapy.\n* Evidence or history of any other disease that in the opinion of the investigator would put the patient at risk through study participation, or would affect the study analyses if the disease exacerbated during the study.\n* Legal incapacity or other circumstances that render the subject unable to understand the nature, scope and possible consequences of the study.\n* Clinically significant abnormal findings or condition (other than kidney stone), which might, in the opinion of the Investigator, interfere with study evaluations or pose a risk to subject safety during the study.'}, 'identificationModule': {'nctId': 'NCT05213702', 'briefTitle': 'A RCT to Evaluate the Efficacy and Safety of Automated Needle Targeting (ANT-X) System Compared to Traditional Free Hand Puncture for Renal Access in Percutaneous Nephrolithotomy (PCNL)', 'organization': {'class': 'OTHER', 'fullName': 'University of Malaya'}, 'officialTitle': 'A Randomized Controlled Trial to Evaluate the Efficacy and Safety of Automated Needle Targeting (ANT-X) System Compared to Traditional Free Hand Puncture for Renal Access in Percutaneous Nephrolithotomy (PCNL) Performed by Urologists in Training.', 'orgStudyIdInfo': {'id': 'NDR-CT0023'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Traditional free hand puncture for renal calyx access', 'description': 'For human PCNL, we target 60 cases of PCNL, 30 ANT-X puncture and 30 traditional free hand puncture performed by 4 urologic trainees(15 cases per urologic trainee).', 'interventionNames': ['Device: Renal Calyx punture with traditional free hand or ANT-X device']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'RObotic ANT-X device puncture for renal calyx access', 'description': 'For human PCNL, we target 60 cases of PCNL, 30 ANT-X puncture and 30 traditional free hand puncture performed by 4 urologic trainees(15 cases per urologic trainee).', 'interventionNames': ['Device: Renal Calyx punture with traditional free hand or ANT-X device']}], 'interventions': [{'name': 'Renal Calyx punture with traditional free hand or ANT-X device', 'type': 'DEVICE', 'description': "ANT-X device is a software-controlled automated electromechanical arm.

ANT-X device is actually a Delta parallel robot implementing inverse kinematics to achieve effector's movement. Parallel structures excel in their great stiffness and high positioning accuracy. Most of the main components of ANT-X robot are made up of medical grade Polyether ether ketone (PEEK) material. PEEK is preferred to build the robot because it is radiolucent and lightweight while being able to provide relatively high material strength.
