About

This investigates the outcomes of a surgical technique using the patient's own abdominal wall muscles to help contract the bladder in patients with urinary retention

Full description

This study is about a surgery called Rectus Abdominis Detrusor Myoplasty (RADM). In this surgery, a small piece of the belly muscle is moved and wrapped around your bladder to help it squeeze and empty urine. Doctors are studying this surgery because current treatments, like catheters or nerve implants, don't always work for people whose bladders don't contract on their own. This study monitors the patients' progress for a year following this surgery.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Hypo- or acontractility of the bladder documented on urodynamic testing
• Injury >1 year ago for spinal cord injury patients, no improvement in contractility with time
• Failed sacral nerve stimulation implant for urinary retention treatment (If previously implanted)
• Irreversible non-neurogenic bladder acontractility/hypocontractility (i.e myogenic failure after chronic obstruction, aging, frailty, idiopathic)
• Undergoing RADM

Exclusion criteria

• Documented bladder outlet obstruction
• Spinal cord lesion above T12
• Upper motor neuron lesion (i.e. multiple sclerosis, stroke)
• Rectus diastasis, significant abdominal wall hernia, or other anatomic barrier to rectus flap harvest
• Life expectancy <10 years
• Pregnant at time of surgery
