Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Microbial community structure in patients with CO urolithiasis	Alpha and beta diversity, principal coordinate analysis, and phylogenetic trees of the bacterial and fungal microbial community from mid-stream voided urine sample, urine sample collected from the bladder, kidney stone fragment, and a renal papillae biopsy specimen.	Day 1
Primary	Microbial community structure in patients with RCC	Alpha and beta diversity, principal coordinate analysis, and phylogenetic trees of the bacterial and fungal microbial community from catheterized urine specimen from the bladder, a biopsy of the tumor, and a biopsy of normal-appearing renal papillae specimen.	Day 1
Primary	Microbial community structure in healthy participants	Alpha and beta diversity, principal coordinate analysis, and phylogenetic trees of the bacterial and fungal microbial community from clean-catch urine specimen.	Day 1
