However, selection criteria remain vague and no investigators have assessed the practicality of using various post-procedural drainage strategies in the ambulatory setting. In this study we establish a set of inclusion and exclusion criteria for aPCNL, compare outcomes between aPCNL patients and those admitted following PCNL, and incorporate a variety of \u201cexit\u201d strategies including Double-J stent, ureteropelvic junction (UPJ) stent and totally tubeless techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      We developed inclusion and exclusion criteria to determine patient eligibility for aPCNL. Between January 2014 and December 2016, 52 out of 145 patients met criteria for aPCNL and 47 of these patients were ultimately discharged on the same day. Forty-seven of the remaining 98 patients who were admitted following PCNL were randomly selected as a control group. Primary outcomes included stone-free status, emergency department (ED) visits and hospital readmissions within the 6-week post-operative period.
