Value of an Integral Color Scale on Urine Collection Bags Versus Use of a Strip in Description of Hematuria.

Study Overview
=================
Brief Summary
-----------------
The investigators hypothesize that incorporation of a colorimetric scale on urine collection bags to estimate degree of hematuria would allow better characterization of urine by healthcare staff thus leading to improved patient care.
