Methods: Between 2011 and 2024, 107 antegrade stent placement procedures performed in 71 pediatric patients aged 0\u201312 years who could not undergo retrograde double-J stent placement were retrospectively analyzed. According to the morphologic structure of the ureter, four categories were classified as normal, straight\/slightly angled, S-shaped, and spiral-shaped. Functional success was evaluated by comparing the results of ultrasonography and Tc-99m MAG3 scintigraphy before and after the procedure. Results: Technical success rate was 99.1% and functional success rate was 84.1%. Intra-procedural complication rate was 5.6% and post-procedural complication rate was 39.3%. According to morphologic classification, the functional success rate was lowest in spiral-shaped ureters with 79.5%, but this difference was not statistically significant (p = 0.775). There was no significant correlation between stent diameter, balloon dilatation, and degree of hydronephrosis and functional success. Conclusions: Antegrade ureteral stent placement is a safe method with high technical success and acceptable complication rates in pediatric patients. The developed ureteral morphologic classification may guide clinical practice.<\/jats:p>","DOI":"10.3390\/jcm14010246","type":"journal-article","created":{"date-parts":[[2025,1,3]],"date-time":"2025-01-03T07:10:17Z","timestamp":1735888217000},"page":"246","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Antegrade Ureteral Stenting in Pediatric Patients: Introducing a Novel Ureteral Morphological Classification and a New Perspective on Functional Success"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1142-213X","authenticated-orcid":false,"given":"Mustafa","family":"Maz\u0131can","sequence":"first","affiliation":[{"name":"Interventional Radiology Department, Adana Dr. Turgut Noyan Application and Research Center, Ba\u015fkent University, 01250 Adana, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5760-1777","authenticated-orcid":false,"given":"Ismail","family":"Karluka","sequence":"additional","affiliation":[{"name":"Interventional Radiology Department, Adana Dr. Turgut Noyan Application and Research Center, Ba\u015fkent University, 01250 Adana, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdulkerim","family":"Temiz","sequence":"additional","affiliation":[{"name":"Pediatric Surgery Department, Adana Dr. Turgut Noyan Application and Research Center, Ba\u015fkent University, 01250 Adana, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8581-8685","authenticated-orcid":false,"given":"Cagatay","family":"Andic","sequence":"additional","affiliation":[{"name":"Interventional Radiology Department, Adana Dr. Turgut Noyan Application and Research Center, Ba\u015fkent University, 01250 Adana, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1005","DOI":"10.1148\/radiographics.22.5.g02se081005","article-title":"Complications of ureteral stent placement","volume":"22","author":"Dyer","year":"2002","journal-title":"Radiographics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"678","DOI":"10.1016\/S0022-5347(17)57326-7","article-title":"Experience with new double J ureteral catheter stent","volume":"120","author":"Finney","year":"1978","journal-title":"J.
