Bladder leak point pressure: the measure for sphincterotomy success in spinal cord injured patients with external detrusor-sphincter dyssynergia
Abstract
Transurethral resection of the external sphincter in patients with spinal cord injury and detrusor-external sphincter dyssynergia has high failure and reoperation rates. Retrospectively we examined elevated bladder leak point pressure after transurethral resection of the external sphincter as an indicator of failure. A total of 55 spinal cord injury patients (mean age 50 years) underwent 1 or more sphincter resections, most recently a mean of 11 years ago. We reviewed the most recent urodynamic studies for bladder leak point pressure, bladder compliance and persisting external detrusor-sphincter dyssynergia. Each patient was assessed for the presence of an indwelling catheter, upper tract damage, stones, bacteriuria, autonomic dysreflexia and vesicoureteral reflux. The incidence of each of these urodynamic and clinical parameters among patients with bladder leak point pressure less than 40 cm. water was compared to the incidence among those with bladder leak point pressure greater than 40 cm. water. Patients with bladder leak point pressure greater than 40 cm. water had a significantly higher incidence of upper tract damage (p = 0.021) and persisting external detrusor-sphincter dyssynergia (p = 0.00008). The incidence of an ind...Continue Reading
