Brief summary

The purpose of this study is to collect descriptive performance data using the MONARCH Platform, Urology (a novel robotic device) to perform mini-percutaneous nephrolithotomy (kidney stone removal) procedures. Data gathered from this study will be used to optimize the robotic platform and inform training and education material for the future users.

Interventions

Eligible participants will be enrolled to undergo robotic-assisted PCNL using the MONARCH Platform, Urology for the removal of kidney stones. The MONARCH Platform, Urology is a novel flexible robotic device that enables the clinician to obtain both transurethral and percutaneous access to a participant's kidney under continuous visualization for therapeutic application (for example, stone removal).

Inclusion criteria

* Simple renal caliceal and/or pyelo stone(s), greater than or equal to (\>=) 10 millimeter in size identified on computerized tomography (CT) scan, and appropriate for Percutaneous nephrolithotomy (PCNL) treatment according to American Urological Association (AUA) guidelines * Normal upper tract anatomy, amenable to PCNL and ureteroscopy * Body mass index less than (\<) 40 kilogram-meter squared * Participants with a percutaneous tract length \<15 centimeter as measured by the estimation of the skin to stone or skin to appropriate calyx for treatment through a CT scan * Participant is an appropriate candidate for a mini-PCNL based on the clinical guidelines and investigator assessment Pre-Operative

Exclusion criteria

* Any medical or physical condition/limitation that would contraindicate a conventional ureteroscopy or PCNL \[for example, atypical interposition of visceral organs (bowel, spleen, or liver)\] in the supine position. This assessment will be made by the investigator team * Participation in any other clinical trial 30-days before and throughout the duration of the study that might impact the results * A solitary functioning kidney * Female subjects who are pregnant or nursing or those of childbearing potential refusing a pregnancy test * Presence of ureteral impacted stones * Presence of ureteral obstruction * Presence of untreated urinary tract infection, urosepsis * Inability to give consent * Presence of a renal mass which has not been investigated * Staghorn stone * Participant has an electrically or magnetically activated implanted medical device * Significant pharmacological anticoagulant therapy or uncorrected bleeding diathesis * Tumor in the probable access tract area and potential malignant renal tumor Intra-Procedure

Recruitment details

Participants aged 22 years or older with simple renal caliceal and/or pyelo stone(s), greater than or equal to 10 millimeters in size identified on computed tomography scan, and appropriate for percutaneous nephrolithotomy (PCNL) treatment according to American Urological Association guidelines were considered for the study. Participants were given the Informed Consent Form to read, ask questions, and sign prior to any study procedures being performed or data being collected.

Pre-assignment details

This was a single-arm study where all participants received treatment with the MONARCH™ Platform, Urology system.
