OBJECTIVE: To study the effects of pudendal nerve block with phenol on detrusor-sphincter dyssynergia in patients with spinal cord injury (SCI).
DESIGN: Before-after trial performed by using a consecutive sample.
SETTING: Rehabilitation hospital affiliated with a medical school.
PATIENTS: Twenty-two male SCI patients (mean age, 46.3+/-11.9y; mean duration postinjury, 2.7y) with voiding dysfunction resulting from external urethral sphincter hypertonicity.
INTERVENTION: Pudendal nerve block with 5% phenol solution under the guidance of electric stimulator.
MAIN OUTCOME MEASURES: Outcomes were measured using (1) postvoid residual volume, maximal detrusor pressure, leak point pressure, bladder volume at the first uninhibited contraction, maximal bladder capacity, and urethral pressure profile; (2) rectoanal rest and squeeze pressures; and (3) quality of life measures for urination, quantified by the Quality of Life Index (QLI). Changes in bowel habit or autonomic dysreflexia were recorded.
RESULTS: The mean decrease in postvoid residual volume was 242.8mL (mean decrease, 66%) after treatment (P<.001). The mean reduction in leak point pressure and maximal detrusor pressure were 37.1cmH(2)O and 43.3cmH(2)O, respectively (P<.05). The mean QLI significantly improved from -.74+/-.38 to.42+/-.47 (P<.001). The rectoanal pressures showed no significant difference. No complaints of fecal incontinence or other complications were noted after treatment.
CONCLUSION: Pudendal nerve block performed by using 5% phenol solution was safe, easy to perform, and effective as a treatment for detrusor-sphincter dyssynergia in selected patients with SCI.
