Abstract
We deeply appreciate the authors' inquiries about our report, and we believe that our answers will provide more details about the topic of insignificant residual fragments after percutaneous nephrolithotomy. We do agree that residual fragments that remain after stone disintegration could have different behavior than that of the originally left peripheral caliceal stones. In our report, 1 Osman Y.

Therefore, it is difficult to draw solid conclusions of whether primary fragmented stones or left stones could have an effect on the growth of residual stones. We showed that the median stone size had significantly increased from 5 mm (interquartile range 1) to 20 mm (interquartile range 14) during the follow-up period (P < .001). Although this information is crucial to determine the rate of residual fragment growth, it must be calculated prospectively to accurately detect the interval to a significant increase in size.
