			*Retrospective study design limits ability to control for confounders
			*Single-center study may limit generalizability
			*Stone composition and size were not consistently documented
			*Time from symptom onset to urinalysis was variable
			*Absence of hematuria should not alter workup in patients with high clinical suspicion for nephrolithiasis
