Case report: Successful staged ureteroscopic treatment of a 5 cm staghorn renal calculus. Case Reports in Urology 2012:873069.2090-696Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:10381371It is widely accepted that percutaneous nephrostolithotorny (PCNL) is the standard of choice for the removal of large staghorn renal calculi. Although data exists supporting a stagad ureteroscopic as an alternate treatment for stones up to 3 cm in select patients, little data exists to support a ureteroscopic approach for stones as large as 5 cm. We present a case of a 68 year old female with a 5 cm staghorn renal calculus managed successfully with a staged ureteroscopic approach. A staged ureteroscopic approach can be effective in treating stones as large as 5 cm.en-USJournal Article2013-03-0810.1155/2012/873069
