Urodynamics of mice in sham or moderate T10 spinal contusion injury groups.

(A and B) Representative EUS EMG activity and bladder pressure recordings (A) with magnified portions (B, rectangle in A) during micturition in the sham groups. Arrows in B (red: bladder contraction; green: EUS contraction) indicate the alternating (coordinated) contractions of the detrusor and the EUS during voiding. (C and D) Representative EUS EMG activity and bladder pressure recordings (C) with magnified portions (D, rectangle in C) during micturition in animals with moderate (70 kdyn) spinal contusion injuries. Arrows in D indicated the co-contractions (dyssynergia) of the detrusor and the EUS during voiding. n = 5 for sham or mice treated with 70 kdyn T10 contusional spinal contusion injuries tested for urodynamics. EMG: Electromyography; EUS: external urethral sphincter; kdyn: kilodyne. 1 dyn = 10^–5 N.
