CMG parameters measured from the 1st to 5th cystometrograms (CMGs) performed during the prolonged (2 h) urinary retention induced by posttibial nerve stimulation (post-TNS) inhibition. A: bladder capacity. B: voiding efficiency. C: residual volume. D: duration of bladder contraction. E: amplitude of bladder contraction. F: area under contraction curve. Parameters in A, B, D, and E are normalized to the control values, and in C residual volumes are normalized to the control bladder capacity. TNS: 5 Hz, 0.2 ms, 4–6T = 2.0–8.4 V. *Significantly (P < 0.05) different from the control (one-way ANOVA); n = 9 cats.
