The latissimus dorsi bladder myoplasty to assist detrusor function

The objective of this study was to evaluate whether an innervated skeletal muscle might augment detrusor function.

Description
Summary:The objective of this study was to evaluate whether an innervated skeletal muscle might augment detrusor function. In four dogs we performed the latissimus dorsi myoplasty, a transfer of the latissimus muscle as an innervated free flap wrapped around the bladder. Stimulation of the latissimus dorsi free flap initially achieved an average bladder pressure of 45.8 +/- 8.41 cm H2O, sufficient for partial evacuation. After 4 months the muscle generated a maximal pressure of 82 cm H2O, resulting in an evacuation of 27.7%. For selected patients, the latissimus dorsi bladder myoplasty may provide an alternative to intermittent catheterization in the future.
