All the children underwent transabdominal US. In children with\u00a0MCDK, we calculated cyst-to-kidney volume ratios (volume of the largest cyst\/volume of the MCDK) and in the control\u00a0group the volume ratios of the renal pelvis and the largest calyx (volume of the pelvis or largest calyx\/volume of the ipsilateral\u00a0hydronephrotic kidney). Ellipsoid formula was used to calculate kidney and pelvis volumes. Sphere volume formula was used\u00a0to calculate the largest cyst and calyx volumes.Results: The mean cyst-to-kidney volume ratio (0.38\u00b10.21) was significantly\u00a0higher than the mean volume ratios of the renal pelvises (0.10\u00b10.05) and the largest calyces (0.04\u00b10.02) (p&lt;0.05). There was\u00a0no significant correlation between cyst-to-kidney volume ratio and the ages of the children (r=0.141, p=0.541).Conclusions:\u00a0With the aid of both the qualitative sonographic criteria and the newer data that we have proposed, US is a useful tool in the\u00a0initial diagnosis of MCDK and for differentiation of MCDKs from grade IV hydronephrotic kidneys in children. The cyst-tokidney\u00a0volume ratio is independent of age and thus, it can be helpful in the diagnosis of unilateral MCDK at any age.\u00a0<\/jats:p>","DOI":"10.11152\/mu-850","type":"journal-article","created":{"date-parts":[[2017,3,3]],"date-time":"2017-03-03T09:29:32Z","timestamp":1488533372000},"page":"159","source":"Crossref","is-referenced-by-count":0,"title":["Cyst-to-kidney volume ratio in the sonographic diagnosis of unilateral multicystic dysplastic kidney in children"],"prefix":"10.11152","volume":"19","author":[{"given":"Sevin","family":"Ayaz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alper","family":"Dilli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salih Sinan","family":"G\u00fcltekin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00dcmit Ya\u015far","family":"Ayaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2017,4,22]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/850\/948","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/850\/948","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,4,22]],"date-time":"2017-04-22T16:33:25Z","timestamp":1492878805000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/850"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,4,22]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2017,4,22]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-850","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2017,4,22]]}}}
