Re: Ito et al.: The Most Reliable Preoperative Assessment of Renal Stone Burden as a Predictor of Stone-free Status After Flexible Ureteroscopy With Holmium Laser Lithotripsy: A Single-center Experience (Urology 2012;80:524-528)

摘要

We congratulate the authors for demonstrating that among the 3 parameters of stone burden (ie, cumulative stone diameter [CSD], stone surface area [SA], and stone volume [SV]), the SV and CSD were significantly and independently inversely related to the success rate with the use of flexible ureteroscopy and the SA was found to have a lower clinical utility and priority as a predictor of stone-free status after ureteroscopy.
