We analyzed preoperative, intraoperative, and postoperative variables of the patients to evaluate the efficacy and reliability of PCNL procedures. <b><i>Results:<\/i><\/b> Patients were categorized as Grade I, II, III, and IV, and the patients of each grade were 85 (19.32%), 39 (8.86%), 213 (48.41%), and 103 (23.41%), respectively. In Grade IV, the total operative time (min) for the PL and HLL groups was 137.7 \u00b1 47.79 and 134.27 \u00b1 53.38, respectively (<i>p<\/i> = 0.744). The variation in laboratory examination values including \u0394HGB (g\/L), \u0394HCT, \u0394PCT, and \u0394Cr (\u03bcmol\/L) for PL and HLL groups was 19 \u00b1 11.23\/12 \u00b1 15.42 (<i>p<\/i> = 0.012), 0.057 \u00b1 0.034\/0.038 \u00b1 0.045 (0.009), 0.027 \u00b1 0.034\/0.026 \u00b1 0.034 (0.702), and 3.07 \u00b1 17.4\/20.54 \u00b1 65.93 (0.692), respectively. The postoperative hospitalization day was 8.94 \u00b1 4.2 and 7.73 \u00b1 2.75 (<i>p<\/i> = 0.015), respectively. As for the stone-free rate (SFR), the SFRs for PL and HLL were 48.15% (<i>n<\/i> = 39\/81) and 59.09% (<i>n<\/i> = 13\/22) (<i>p<\/i> = 0.363), respectively. <b><i>Conclusions:<\/i><\/b> HLL showed a comparable advantage of not only decreased postoperative hemoglobin and hematocrit but also fewer postoperative hospitalization days. Based on the results of our retrospective study, for those Grade IV kidney stone patients who have a risk of bleeding before PCNL operation, HLL can be a considerable treatment option. Besides, in consideration of reducing human care cost, HLL which showed fewer hospitalization days, would be more welcome by patients. <\/jats:p>","DOI":"10.1159\/000509043","type":"journal-article","created":{"date-parts":[[2020,8,24]],"date-time":"2020-08-24T21:00:34Z","timestamp":1598302834000},"page":"45-51","source":"Crossref","is-referenced-by-count":6,"title":["Pneumatic Lithotripsy versus Holmium Laser Lithotripsy in Percutaneous Nephrolithotomy for Patients with Guy\u2019s Stone Score Grade IV Kidney Stone"],"prefix":"10.1159","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7223-4998","authenticated-orcid":false,"given":"Yuxiang","family":"Hong","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingtao","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaoming","family":"Hou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohong","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junhong","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2020,8,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2012.03.052"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/bju.13828"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2014.05.095"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2009.01.023"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000161171.67806.2a"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2016.05.090"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s11255-014-0787-x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2016.01.047"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2010.12.026"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.4274\/balkanmedj.2017.1631"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.asjsur.2015.03.010"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/s0302-2838(03)00006-x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1177\/1756287215617674"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1080\/0886022x.2018.1459306"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1089\/end.2011.0055"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2011.12.061"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-017-2001-0"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s12262-016-1473-2"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1089\/end.2014.0199"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1159\/000448692"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpurol.2012.03.004"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2015.16353"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1111\/bju.13418"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/509043","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/509043","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:42:56Z","timestamp":1745422976000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000509043"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,23]]},"references-count":23,"journal-issue":{"issue":"1-2","published-online":{"date-parts":[[2021,1,20]]},"published-print":{"date-parts":[[2021,2,9]]}},"URL":"https:\/\/doi.org\/10.1159\/000509043","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,23]]}}}
