ObjectiveTo evaluate the effects of transrectal ultrasound-guided trocar catheter transurethral botulinum toxin A (BTX-A) injection into the external urethral sphincter (EUS) for treating detrusor external sphincter dyssynergia (DESD) in men with spinal cord injury (SCI).DesignDescriptive study.SettingHospital rehabilitation department.ParticipantsPatients (N=15; mean age, 40.5y; range, 22–64y) with suprasacral SCI with confirmed DESD determined by urodynamic study.InterventionsA single dose of 100U BTX-A was injected into the EUS via transrectal ultrasound-guided trocar catheter transurethral injection.Main Outcome MeasuresMaximal detrusor pressure, detrusor leak point pressure, maximal pressure on static urethral pressure profilometry, postvoid residual volume, and maximal flow rate.ResultsAfter BTX-A transurethral injection, 4 (28.5%) patients showed an excellent result and 7 (46.7%) patients showed an improved result, whereas 4 (28.5%) patients experienced treatment failure. The overall success rate was 75.2%. We observed a significant decrease in static urethral pressure (P<.05) and detrusor leak point pressure after treatment (P<.05), but not in detrusor pressure. The postvoid residual volume were significantly decreased in the fourth week after treatment (P<.05).ConclusionsTransrectal ultrasound-guided trocar catheter transurethral BTX-A injection into the EUS effectively suppresses or ameliorates DESD. A potential advantage of the method is that ultrasound guidance may not be necessary in the next injection.
