The mechanics of urine during its transport
from the renal pelvis to the bladder is of great interest
for urologists. The knowledge of the different physical
variables and their interrelationship, both in physiologic
movements and pathologies, will help a better diagnosis
The objective of this chapter is to show the physics principles
and their most relevant basic relations in urine
transport, and to bring them over the clinical world. For
that, we explain the movement of urine during peristalsis,
ureteral obstruction and in a ureter with a stent.
This explanation is based in two tools used in bioengineering:
the theoretical analysis through the Theory of concontinuous
media and Ffluid mechanics and computational
simulation that offers a practical solution for each
scenario. Moreover, we review other contributions of
bioengineering to the field of Urology, such as physical
simulation or additive and subtractive manufacturing techniques.
Finally, we list the current limitations for these
tools and the technological development lines with more
CONCLUSIONS: In this chapter we aim to help urologists
to understand some important concepts of bioengineering,
promoting multidisciplinary cooperation to
offer complementary tools that help in diagnosis and
treatment of diseases.
