Method: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications).  Results: The mean stone size was 12.23 +\/- 5.43 mm (range 6-22mm), located in the inferior (58.33%) and middle (16.76%) calyceal units, renal pelvis (16.67%) and multiple locations (8.33%). All 13 patients were treated with Ho-Yag laser, using dusting technique (25%), fragmentation and extraction of the calculi (58.33%) and mixed technique (16.67%). We did not have any severe perioperative complication. After 90 days, nine patients (75%) were considered stone free.  Conclusion: Our data suggest that F-URS is a safe and feasible choice for the treatment of kidney stones in patients with renal ectopic and fusion anomalies.<\/jats:p>","DOI":"10.1590\/1806-9282.63.08.685","type":"journal-article","created":{"date-parts":[[2017,9,30]],"date-time":"2017-09-30T19:30:15Z","timestamp":1506799815000},"page":"685-688","source":"Crossref","is-referenced-by-count":7,"title":["Flexible ureterorenoscopy in position or fusion anomaly: Is it feasible?"],"prefix":"10.1590","volume":"63","author":[{"given":"Rafael Haddad","family":"Astolfi","sequence":"first","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gustavo","family":"Freschi","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando Figueiredo","family":"Berti","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nelson","family":"Gattas","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilson Rica","family":"Molina Junior","sequence":"additional","affiliation":[{"name":"University of Colorado,  USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex","family":"Meller","sequence":"additional","affiliation":[{"name":"Unifesp,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1053\/j.ackd.2008.10.002","article-title":"Economics and cost of care of stone disease","volume":"16","author":"Lotan Y","year":"2009","journal-title":"Adv Chronic Kidney Dis"},{"issue":"4","key":"ref2","first-page":"518","article-title":"Custo do tratamento hospitalar da lit\u00edase urin\u00e1ria para o Sistema \u00danico de Sa\u00fade brasileiro","volume":"9","author":"Korkes F","year":"2011","journal-title":"Einstein"},{"key":"ref3","series-title":"Campbell's urology","first-page":"3106","volume-title":"Anomalies of the upper urinary tract","author":"Shapiro E","year":"2012","edition":"10th ed"},{"issue":"6","key":"ref4","doi-asserted-by":"crossref","first-page":"1285","DOI":"10.1016\/j.urology.2014.07.041","article-title":"Flexible ureterorenoscopy for the treatment of kidney stone within pelvic ectopic kidney","volume":"84","author":"Bozkurt OF","year":"2014","journal-title":"Urology"},{"issue":"3","key":"ref5","doi-asserted-by":"crossref","first-page":"372","DOI":"10.1016\/S0090-4295(99)80003-X","article-title":"The case for primary endoscopic management of upper urinary tract calculi: II.
