Simple Explanation

This study investigates the effects of imidafenacin, a medication, on bladder function in patients with spinal cord injury (SCI) who use indwelling bladder catheters. The researchers aimed to see if imidafenacin could improve bladder capacity and compliance, and reduce bladder pressure in these patients. The study found that imidafenacin may improve bladder parameters and reduce complications in SCI patients with indwelling catheters.

Study Duration
July 2010 and December 2012
Participants
34 patients with SCI
Evidence Level
Not specified

Key Findings

  • 1
    Imidafenacin increased the cystometric volume from 246.0 to 321.5 ml (median, P = 0.002).
  • 2
    Detrusor compliance increased from 6.67 ml cm−1 H2O to 8.98 ml cm −1 H2O (median, P = 0.012).
  • 3
    All three patients who had VUR fully recovered with imidafenacin treatment.

Research Summary

This retrospective study investigated the effect of imidafenacin on urodynamic parameters in SCI patients with indwelling bladder catheters. The study found that imidafenacin significantly improved cystometric capacity and detrusor compliance. The authors conclude that imidafenacin is a safe drug that may improve urodynamic parameters and alleviate bladder complications in patients with SCI.

Practical Implications

Improved Bladder Management

Imidafenacin can be an appropriate bladder management option in patients with SCI who are contraindicated to CIC.

Vesico-urethral Reflux (VUR) Treatment

Imidafenacin may be effective in treating VUR by increasing bladder volume and compliance.

Autonomic Dysreflexia (AD) Management

While imidafenacin improved AD in some patients, it may not be sufficient as a standalone treatment, and preventing AD is strongly encouraged during bladder management in SCI patients.

Study Limitations

  • 1
    Retrospective design
  • 2
    Lack of a control group
  • 3
    Small number of patients and short follow-up period
