We have read with interest the article recently published in the Journal of Endourology by Peplinski et al "The Effect of Laser Fiber Cleave Technique and Lithotripsy Time on Power Output". First, we agree with the conclusion of founding no benefit of using any specific cleaving technique. The authors did not include this parameter in their evaluations; this parameter is a key element in the experiments as the results might vary. Finally cleaving the laser fibers may bring other benefits: the fiber tip damage and cracking may allow back burns and retrograde laser emissions becoming a potential risk to damage the ureteroscope. For this reason we continuously cut the fiber tip each 10.000 J (achieved every 15 minutes of laser lithotripsy approximately).
