M\u00e9todos: foram revisados os dados de todos os pacientes maiores de 18 anos de idade submetidos \u00e0 NL entre janeiro de 2006 e maio de 2013 em nossa Institui\u00e7\u00e3o. \u00cdndice de Charlson, escore ASA, fun\u00e7\u00e3o renal pela equa\u00e7\u00e3o e est\u00e1gio de MDRD (Modification of Diet in Renal Disease), achados de tomografia computadorizada (TC) pr\u00e9-operat\u00f3ria, complica\u00e7\u00f5es pela classifica\u00e7\u00e3o de Clavien-Dindo e taxa de convers\u00e3o foram analisados. Determinaram-se os fatores de risco para convers\u00e3o por meio de regress\u00e3o log\u00edstica. Resultados: oitenta e quatro pacientes foram submetidos \u00e0 LN, sendo que 16 (19%) tiveram seu procedimento convertido para cirurgia aberta devido \u00e0 forte ader\u00eancia do hilo renal aos \u00f3rg\u00e3os adjacentes. Outras causas associadas \u00e0 convers\u00e3o foram sangramento excessivo (n=6) e les\u00e3o do intestino grosso (n=3). Na an\u00e1lise univariada, cirurgia renal pr\u00e9via, borramento da gordura perirrenal, abscesso renal, abscesso perirrenal, abscesso pararrenal, f\u00edstula, ader\u00eancia ao f\u00edgado ou ba\u00e7o e ader\u00eancia ao intestino foram associados \u00e0 convers\u00e3o. Na an\u00e1lise multivariada, abscesso pararrenal e ader\u00eancia ao intestino foram fatores de risco significativos para a convers\u00e3o. Conclus\u00e3o: abscesso pararrenal e ader\u00eancia ao intestino demonstrados na TC pr\u00e9-operat\u00f3ria s\u00e3o fatores de risco de convers\u00e3o para cirurgia aberta em LN por urolit\u00edase.<\/jats:p>","DOI":"10.1590\/0100-6991e-20192092","type":"journal-article","created":{"date-parts":[[2019,6,19]],"date-time":"2019-06-19T19:24:44Z","timestamp":1560972284000},"source":"Crossref","is-referenced-by-count":3,"title":["Nefrectomia laparosc\u00f3pica por nefrolit\u00edase: quando \u00e9 melhor evitar."],"prefix":"10.1590","volume":"46","author":[{"given":"Alexandre","family":"Danilovic","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thiago Augusto Cunha","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio Carvalho","family":"Vicentini","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio C\u00e9sar Miranda","family":"Torricelli","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni Scala","family":"Marchini","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Mazzucchi","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Willian Carlos","family":"Nahas","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Srougi","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2019]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1016\/j.eururo.2012.03.052","article-title":"Prevalence of kidney stones in the United States","volume":"62","author":"Scales Jr CD","year":"2012","journal-title":"Eur Urol"},{"issue":"5","key":"ref2","doi-asserted-by":"crossref","first-page":"799","DOI":"10.1016\/S0272-6386(04)01131-X","article-title":"ESRD caused by nephrolithiasis: prevalence, mechanisms, and prevention","volume":"44","author":"Jungers P","year":"2004","journal-title":"Am J Kidney Dis"},{"issue":"2","key":"ref3","doi-asserted-by":"crossref","first-page":"316","DOI":"10.1016\/j.juro.2014.05.006","article-title":"Medical management of kidney stones: AUA guideline","volume":"192","author":"Pearle MS","year":"2014","journal-title":"J Urol"},{"issue":"1","key":"ref4","doi-asserted-by":"crossref","first-page":"W1","DOI":"10.2214\/AJR.10.4375","article-title":"Patterns of fat stranding","volume":"197","author":"Thornton E","year":"2011","journal-title":"AJR Am J Roentgenol"},{"issue":"4","key":"ref5","doi-asserted-by":"crossref","first-page":"681","DOI":"10.1089\/end.2007.0291","article-title":"Laparoscopic nephrectomy outside gerota fascia for management of inflammatory kidney","volume":"22","author":"Duarte RJ","year":"2008","journal-title":"J Endourol"},{"issue":"5","key":"ref6","doi-asserted-by":"crossref","first-page":"559","DOI":"10.1007\/s00240-012-0466-2","article-title":"Retroperitoneoscopic nephrectomy for non-functioning kidneys related to renal stone disease","volume":"40","author":"Tepeler A","year":"2012","journal-title":"Urol Res"},{"issue":"6","key":"ref7","doi-asserted-by":"crossref","first-page":"461","DOI":"10.7326\/0003-4819-130-6-199903160-00002","article-title":"A more accurate method to estimate glomerular filtration rate from serum creatinine: a new prediction equation.
