Given conflicting results and a lack of robust data, we looked at the results of URSL in patients with CKD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Over a 6.5-year period (March 2012\u2013July 2018), prospective outcomes were recorded for consecutive patients who underwent URSL for ureteral or renal stones. The inclusion criteria were all patients with CKD II\u2013V. Renal function was checked preoperatively and at a minimum of 6 months postprocedure. Data were collected and analyzed for patient and stone demographics, procedural and postoperative details, and complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Over the study period, 277 patients with preoperative CKD stage II\u2013V were included with a male:female ratio of 188:89 and a mean age of 66.6 years. The mean preoperative estimated glomerular filtration rate (eGFR) (mL\/minute) was 63 (range: 14\u201389, \u00b118) with 167 (60.2%) CKD II, 70 (25.2%) CKD IIIa, 27 (9.7%) CKD IIIb, 10 (3.6%) CKD IV, and 3 (1%) CKD V patients. The mean single stone size was 9.6\u2009mm (range: 3\u201337\u2009mm, \u00b15.2) and 35.3% had multiple stones. The stone was located in the ureter for 112 patients, kidney for 137 patients, with 28 patients who had stones in both ureter and kidneys. A pre- and postoperative stent was present in 34.3% to 60% and 82.6% to 100% of patients, respectively, with an access sheath used in 103 (37.8%). The mean operative time was 44.5 minutes, with a stone-free rate of 91.6%. Postoperatively the mean eGFR improved to 68 (\u00b120) (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.002).
