Figure 1. Changes in subtraction cystometry after treatment with BTX-A injections
(A) Terminal detrusor overactivity at reduced cystometric capacity was present before BTX-A treatment. (B) Restoration of maximum cystometric capacity to normal levels, and an improvement in filling detrusor pressure trace had occurred by 4 weeks post-treatment. (C) A further improvement, with almost complete abolition of detrusor overactivity, was noted at 16 weeks post-treatment. Note that the detrusor pressure values recorded here correspond to the end filling pressures, not to the maximum detrusor pressure. Abbreviations: Pabd (red), intra-abdominal pressure (cmH2O); Pdet (purple), detrusor pressure (cmH2O); Pves (light blue), intravesical pressure (cmH2O); Qura (yellow), flow rate of voiding; Vinfus (green), infused volume; Vura (dark blue), volume of voided urine.
