Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis.\n\n\t\u00a0\n\n\t\n\n\tResults: There were no significant differences in age, sex, body mass index, hypertension, diabetes mellitus, pre-surgery hemoglobin, pre-surgery serum creatinine, stone and also surgery-related parameters between the two groups. Stone free rate, surgery time, complication-related parameters, hemoglobin drop, serum creatinine and glomerular filtration rate (GFR) changes were similar in both groups based on univariate analysis. The radiopaque group had higher post-surgery GFR (p=0.04) and longer hospital stay (p=0.009). However, opacity had no effect on these outcomes after multivariate analysis. Higher post-surgery GFR was seen in patient with higher GFR before surgery (p<\/jats:p>","DOI":"10.5152\/tud.2017.14477","type":"journal-article","created":{"date-parts":[[2017,11,10]],"date-time":"2017-11-10T02:12:24Z","timestamp":1510279944000},"page":"490-496","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of the outcomes of complete supine percutaneous nephrolithotomy in patients with radiopaque and radiolucent kidney stones"],"prefix":"10.5152","volume":"43","author":[{"given":"Siavash","family":"Falahatkar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gholamreza","family":"Mokhtari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atiyeh","family":"Amin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ehsan","family":"Kazemnezhad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samaneh","family":"Esmaeili","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadia Rastjou","family":"Herfeh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Falahatkar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"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\/3023\/3019","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T18:08:04Z","timestamp":1772647684000},"score":1,"resource":{"primary":{"URL":"https:\/\/urologyresearchandpractice.org\/index.php\/pub\/article\/view\/3023"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,25]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2017,1,1]]}},"URL":"https:\/\/doi.org\/10.5152\/tud.2017.14477","relation":{},"ISSN":["2980-1478"],"issn-type":[{"value":"2980-1478","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7,25]]}}}
