% Papillary deformity refers to the fraction of papillae visualized at the time of surgery with deformity; % Plaque papillary surface area, mean percent of papillary surface covered by white plaque; Stones attached to plaque, stones found attached to papilla on plaque at surgery; Dilated BD, degree of dilatation of Bellini ducts; IMCD/BD, inner medullary collecting duct+Bellini duct, mean number of deposits/mm2 of tissue on μCT; IMCD crystals, HA hydroxyapatite, CaOx, calcium oxalate; Glom, # glomeruli/#mild/#moderate/#global sclerosis; Tub At, cortical tubular atrophy, graded 1–3; IF, cortical interstitial fibrosis graded 1–3; COM, calcium oxalate monohydrate;
small amount hydroxyapatite and acid ammonium urate in 1 stone each.
