Abstract

The authors investigated balloon dilation as a minimally invasive alternative to transurethral external sphincterotomy for the treatment of detrusor-external urethral sphincter dyssynergia (DESD). Seventeen spinal cord-injured men with voiding pressures greater than 60 cm H2O underwent balloon dilation of the external sphincter to 90 F at 4 atm of pressure for 10 minutes. The mean voiding pressures before and 12 months after dilation were 83 cm H2O ± 35 and 37 cm H2O ± 15, respectively (P = .008). There was a significant decrease in residual urine volume, from 163 mL ± 162 to 68 mL ± 59 (P = .05), whereas bladder capacity remained relatively unchanged at 253 mL ± 181 and 230 mL ± 97 (P = .30). Complications included one case of postoperative bleeding necessitating transfusion, two treatment failures, and one bulbous urethral stricture. Fourteen of the 17 patients (82%) now void without the aid of an indwelling catheter or alternative therapy. Balloon dilation has no detrimental effect on erectile function and may improve fertility.
