Participant Flow

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.

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

Unit of analysis: Kidney stones

An adverse event (AE) is defined as any undesirable clinical occurrence in a patient whether or not it is considered to be device related. In addition, the definition of AE applies to any event with an onset post study procedure or to any underlying diseases, present at baseline, that exacerbate in severity post study procedure. All reported AEs must be recorded in the database.
