[Urine analysis. Luis Cifuentes in the transition from art to science].
OBJECTIVE
To emphasize the importance of the study of urine samples as well as the non replaceable figure of Dr. Luis Cifuentes Delatte.


METHODS
We review the methodology of the study of urine samples.


RESULTS
Urine analysis keeps a great diagnostic importance as Dr. Luis Cifuentes Delatte demonstrated, although it unavoidably has suffered modifications due to technological development and social needs.


CONCLUSIONS
We should never forget in our clinical practice urine analysis of the sediment, as Dr. Luis Cifuentes Delatte supported in his time.
