How do you induce the bladder to empty itself with spinal epidurals in men?

Strait catheter. Unfortunately, this complication is all too common in men, it does resolve but may take several hours. As one recovers from a spinal/epidural, the sacral nerve roots are among the last to recover. Autonomic innervation governs urine extrusion-the urinary sphincter dilating and bladder contracting. This reflex is transiently impaired in some. Catheterization may be performed if bladder overfill.
