Popis: Objectives: Biomechanics is the mechanics applied to biology and we hereby review bladder biomechanics in diabetic bladder dysfunction. Methods: The important mechanical properties of bladder tissue include the stress-strain relationship, viscoelasticity and active contraction. Using biaxial mechanical testing methods, the diabetic bladders exhibited non-linear stress-strain mechanical relationships with increasing stiffness at higher stretches in both circumferential and longitudinal directions. Results: The diabetic bladders showed mechanical anisotropy with a greater compliance in the circumferential direction than in the longitudinal direction. The time-course study suggested that diuresis mainly contributed to the “early” changes of the mechanical properties with “late” changes induced by other diabetic effects. Conclusion: The biomechanical study of the urinary bladder has offered a novel understanding of the pathophysiology of diabetic cystopathy and we believe the collaboration of urology and engineering will contribute greatly to the treatment of diabetic bladder dysfunction in the future.
