The MONARCH\u2122 Platform, Urology, is an FDA-cleared robotic platform that may simplify percutaneous access and efficiently treat complex renal stones. In this study, we evaluate the clinical, procedural, and patient-reported outcomes using this technology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>In a preliminary prospective study in two institutions (University of Wisconsin and Indiana University), patients were enrolled to undergo robotic-assisted mini-PCNL with combined ureteroscopic lithotripsy and followed up to 90 days post-procedure. Percutaneous access was gained using electromagnetic guidance while the patient was in a modified supine position. Stones were removed using a handheld controller to manipulate multiple instruments (i.e., retrograde ureteroscope, laser fiber, basket, flexible antegrade suction catheter) and control a fluid management system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Fifteen patients with median (range) linear stone burden of 32.6 (15.0\u201372.8) mm were enrolled. In 100% of cases, percutaneous access was successfully gained using this technology, and in 73.3% of cases this was achieved within a single attempt. Within this limited and highly heterogeneous study population, we achieved a postoperative day 30 median (range) volume reduction in stone burden of 98.8 (51.9\u2013100.0)% and a stone-free rate (\u22644 mm) of 50.0%. One perioperative Grade 3 complication occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our initial experience suggests a future where the MONARCH\u2122 Platform may provide urologists with expanded capabilities for safe and effective treatment of select patients with nephrolithiasis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/08927790261459280","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T12:16:20Z","timestamp":1781266580000},"page":"1129-1135","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Early Evaluation of Safety and Efficacy of Robotic-Assisted Combined IntraRenal Surgery with the MONARCH\n                    <sup>TM<\/sup>\n                    Platform"],"prefix":"10.1177","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5042-0507","authenticated-orcid":false,"given":"Margaret A.","family":"Knoedler","sequence":"first","affiliation":[{"name":"Department of Urology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily C.","family":"Serrell","sequence":"additional","affiliation":[{"name":"Department of Urology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David C.","family":"Dalton","sequence":"additional","affiliation":[{"name":"Department of Urology, Indiana University School of Medicine, Indianapolis, Indiana, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nancy L.","family":"Sehgel","sequence":"additional","affiliation":[{"name":"Scientific Affairs, Johnson &amp;
