Furthermore, outcomes of a modified external stent inserted into the renal pelvis, termed cutaneous pyeloureteral (CPU) stent, remain unexamined. This study investigates outcomes of DJ and CPU stents as methods of trans-anastomotic drainage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>A retrospective analysis identified pediatric patients who underwent RALP between December 2007 and January 2020 at a single tertiary center, where CPU stents were introduced in June 2012. Operative success was defined as improved or stable hydronephrosis without subsequent redo pyeloplasty. Secondary outcomes included stent reinsertion, anesthesia requirements, opioid administration, urinary tract infection (UTI), and bladder spasms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 103 pediatric RALP procedures were analyzed (DJ\u2009=\u200970, CPU\u2009=\u200933). Operative success (DJ\u2009=\u200995.7%, CPU\u2009=\u2009100%,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.55), Society for Fetal Urology (SFU) grade improvement, and length of stay were comparable. Accidental stent expulsion was only seen with CPU stents (9%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.03). Intracorporeal stent migration also occurred more frequently in CPU stents (DJ\u2009=\u20093%, CPU\u2009=\u200915%,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.03). Stent reinsertion, when needed, used a DJ stent with rates of 4% and 9% for DJ and CPU stents, respectively (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.38).

Appreciable differences can inform stent selection, including higher general anesthesia requirements and IV opioid administration among DJ stents and a higher incidence of accidental stent expulsion among CPU stents. In addition, DJ stents were associated with nonsignificant increased rates of UTI and bladder spasm necessitating medication.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/end.2020.1115","type":"journal-article","created":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T04:02:26Z","timestamp":1622606546000},"page":"1616-1622","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Comparative Outcomes of Double-J and Cutaneous Pyeloureteral Stents in Pediatric Robot-Assisted Laparoscopic Pyeloplasty"],"prefix":"10.1177","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9108-1800","authenticated-orcid":false,"given":"Alyssa","family":"Lombardo","sequence":"first","affiliation":[{"name":"University of Chicago Pritzker School of Medicine, Chicago, Illinois, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiffany","family":"Toni","sequence":"additional","affiliation":[{"name":"University of Chicago Pritzker School of Medicine, Chicago, Illinois, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ciro","family":"Andolfi","sequence":"additional","affiliation":[{"name":"Pediatric Urology, Section of Urology, Department of Surgery, Division of the Biological Sciences and Pritzker School of Medicine, The University of Chicago, Chicago, Illinois, USA."},{"name":"The MacLean Center for Clinical Medical Ethics, The University of Chicago, Chicago, Illinois, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohan S.","family":"Gundeti","sequence":"additional","affiliation":[{"name":"Pediatric Urology, Section of Urology, Department of Surgery, Division of the Biological Sciences and Pritzker School of Medicine, The University of Chicago, Chicago, Illinois, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,11,1]]},"reference":[{"key":"e_1_3_5_2_2","unstructured":"Koff SA Mutabagani K.
