Dear Editor:
W
e read the article with great interest and congratulate the authors for recommending an easy, memorizable, user friendly, and applicable classification for the use and duration of postoperative stent placement after ureteroscopy. The authors have mentioned that grade 2 injury (a submucosal lesion with complete tearing of mucosa) as per the postureteroscopy lesion scale was managed by Double-J stent placement for 2 weeks. The Double-J stent, however, was removed by flexible cystoscopy under local anesthesia. Therefore, we are of the opinion that grade 2 injury, although uncomplicated, should be classified as grade IIIa as per the Dindo-modified Clavien classification of surgical complications.
