Comparison of outcomes between RIRS with vacuum\u2010assisted ureteral access sheath (V\u2010UAS) and MPCNL in the treatment of renal stone. <jats:italic>Materials and Methods<\/jats:italic>. 28 patients with 2\u20104\u2009cm renal stone were treated using RIRS with 14\/16\u2009F V\u2010UAS. The outcomes were compared to those who underwent MPCNL with 16\u2009F Amplatz sheath using a matched\u2010pair analysis in a 1\u2009:\u20092 scenario. Matching criteria included stone size, location and laterality, gender, age, BMI, and degree of hydronephrosis. Patients\u2019 demographics, perioperative and postoperative characteristics, complications, stone\u2010free rate (SFR), and auxiliary procedures were compared. <jats:italic>Results<\/jats:italic>. Mean operative times for the RIRS and MPCNL groups were 72.4 \u00b1 21.3 minutes and 67.4 \u00b1 25 minutes (<jats:italic>P<\/jats:italic> = 0.042). Postoperative pain was significantly less in the RIRS group. The initial SFR was 50% for the RIRS group and 73.2% for the MPCNL group (<jats:italic>P<\/jats:italic> = 0.035). The final SFR at postoperative three months improved to 89.3% for the RIRS group and 92.9% for the MPCNL group (<jats:italic>P<\/jats:italic> = 0.681). The auxiliary procedure rates were higher in the RIRS group (42.9% vs. 25%, <jats:italic>P<\/jats:italic> = 0.095). The overall complication rate in the RIRS group was lower, but the significant difference was not found. <jats:italic>Conclusion<\/jats:italic>. In the treatment of 2\u20104\u2009cm renal stone, using V\u2010UAS in RIRS can improve surgical efficiency with lower postoperative early pain scores. Comparing with MPCNL, its initial SFR was more depressed, and there is still a trend towards requiring more auxiliary procedures to achieve comparable final SFR.<\/jats:p>","DOI":"10.1155\/2020\/8052013","type":"journal-article","created":{"date-parts":[[2020,5,16]],"date-time":"2020-05-16T00:44:06Z","timestamp":1589589846000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["RIRS with Vacuum\u2010Assisted Ureteral Access Sheath versus MPCNL for the Treatment of 2\u20104\u2009cm Renal Stone"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8851-7930","authenticated-orcid":false,"given":"Dehui","family":"Lai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongzhong","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xun","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meiling","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingrong","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,5,15]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1089\/end.2009.1534"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2012.11191.x"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2015.07.041"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-2042.2011.02931.x"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1089\/end.2009.0391"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2019.7710"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-012-0991-1"},{"key":"e_1_2_12_8_2","first-page":"512","article-title":"Retrograde intrarenal surgery for renal stones smaller than 2\u2009cm","volume":"51","author":"Ho C.
