All patients were evaluated preoperatively with intravenous pyelography and\/or computed tomography. Intraoperative parameters, post-operative results and complications were recorded. Postoperative success was defined as complete stone clearance and\/or clinically insignificant residual fragments at 3rd month. \n\n\t \n\n\tResults: Preoperative characteristics were similar between sPNL and mPNL groups except previous renal stone operation history and gender. The mean operation time was significantly shorter in the sPNL group (p&lt;0.001). The mean hemoglobin drop was significantly less in the mPNL group (p=0.001), we found a 1.27\u00b11.4 and 0.5\u00b11.3 decrease in mean hemoglobin levels (mg\/dL) in the sPNL and mPNL groups, respectively. Transfusion rate was 1.9% in mPNL and 5.6% in sPNL groups, and the difference was statistically significant (p=0.048). Only one patient in the sPNL group needed angiography and embolization. Postoperative JJ stent insertion rate was significantly higher in the mPNL group (p=0.03). \n\n\t \n\n\tConclusion: Both sPNL and mPNL are safe and effective surgical procedures for lower calyx and\/or pelvis stones smaller than 3 cm. However, use of smaller caliber instruments was associated with a lesser hemoglobin drop and need for transfusion.<\/jats:p>","DOI":"10.5152\/tud.2017.45793","type":"journal-article","created":{"date-parts":[[2017,5,3]],"date-time":"2017-05-03T10:36:38Z","timestamp":1493807798000},"page":"165-170","source":"Crossref","is-referenced-by-count":0,"title":["Is standard percutaneous nephrolithotomy still the standard treatment modality for renal stones less than three centimeters?"],"prefix":"10.5152","volume":"43","author":[{"given":"\u00d6mer","family":"Sar\u0131lar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faruk","family":"\u00d6zg\u00f6r","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Onur","family":"K\u00fc\u00e7\u00fcktop\u00e7u","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Burak","family":"U\u00e7p\u0131nar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehmet Fatih","family":"Akbulut","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Metin","family":"Savun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zafer G\u00f6khan","family":"G\u00fcrb\u00fcz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Murat","family":"Binbay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3111","published-online":{"date-parts":[[2019,7,25]]},"container-title":["Urology Research and Practice"],"original-title":[],"link":[{"URL":"https:\/\/urologyresearchandpractice.org\/index.php\/pub\/article\/download\/2964\/2960","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T18:15:13Z","timestamp":1772648113000},"score":1,"resource":{"primary":{"URL":"https:\/\/urologyresearchandpractice.org\/index.php\/pub\/article\/view\/2964"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,25]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2017,1,1]]}},"URL":"https:\/\/doi.org\/10.5152\/tud.2017.45793","relation":{},"ISSN":["2980-1478"],"issn-type":[{"value":"2980-1478","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7,25]]}}}
