Patients were divided into two groups \u2212 stone-free and residual \u2212 based on pre-and post-SWL imaging. Age, gender, stone location, ellipsoid stone volume (ESV) and side (right\/left), stone density (SD), stone-skin distance (SSD), body-mass index (BMI), Triple-D score (TrD-S), and Quadruple-D score (QrD-S) values were recorded and compared. For TrD-S, SV &lt;150 mm3, SD &lt;600 Hounsfield (HU), and SSD &lt;12 cm were scored in the range of 0\u20133. For QrD-S, lower calyx localization was scored as \u201c0\u201d, and pelvis, middle calyx, and upper calyx stones were scored as \u201c1\u201d in the range of 0\u20134.<\/jats:p>\n                  <jats:p>Results Of a total of 328 patients, 219 (66.8%) were stone-free, 109 (33.2%) had residual stones, 211 were male, and 117 were female. Of the stones, 149 were located in the lower calyx, 118 in the middle calyx, 55 in the renal pelvis, and 6 in the upper calyx. ESV was 95.5 and 120 \u00b5\/L in the two groups, (p:0.001). Cutoff values of TrD-S and QrD-S were 1.5 and 2.5, and area under the curve (AUC) values were 0.65 and 0.67, respectively, (p:0.001).<\/jats:p>\n                  <jats:p>Conclusions The Quadruple-D score is at least as successful as the Triple-D score in predicting SWL success.<\/jats:p>","DOI":"10.1055\/a-2266-3564","type":"journal-article","created":{"date-parts":[[2024,3,13]],"date-time":"2024-03-13T20:02:40Z","timestamp":1710360160000},"page":"533-537","source":"Crossref","is-referenced-by-count":3,"title":["Predicting Stone-free Status based on Quadruple-D and Triple-D Scores after Extracorporeal Shock-Wave Lithotripsy and Comparing With Broad-Spectrum Population"],"prefix":"10.1055","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4745-5160","authenticated-orcid":false,"given":"Alper","family":"Co\u015fkun","sequence":"additional","affiliation":[{"name":"Urology, Kartal Dr. Lutfi Kirdar City Hospital, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Utku","family":"Can","sequence":"additional","affiliation":[{"name":"Urology, Kartal Dr. Lutfi Kirdar City Hospital, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,3,13]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"468","DOI":"10.1016\/j.eururo.2015.07.040","article-title":"EAU Guidelines on Diagnosis and Conservative Management of Urolithiasis","volume":"69","author":"C T\u00fcrk","year":"2016","journal-title":"Eur Urol"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.151.5.923","volume-title":"Extracorporeal shock wave lithotripsy.
