Changes in the Trend in Bladder Emptying Methods in Patients With Spinal Cord Injury: A 20-Year Single-Center Retrospective Study.

Objective: To review trends in bladder emptying methods over a 20-year period in patients with spinal cord injury (SCI) by severity according to the American Spinal Injury Association impairment scale (AIS).

Methods: Medical records of patients with SCI from 1994 to 1998 (group 1) and from 2012 to 2016 (group 2) were retrospectively reviewed. We classified bladder emptying methods according to the International Spinal Cord dataset.

Long-Term Efficacy of Mirabegron Add-On Therapy to Antimuscarinic Agents in Patients With Spinal Cord Injury.

Objective: To evaluate the long-term efficacy of mirabegron add-on therapy in patients with spinal cord injury (SCI) based on an urodynamic study.

Methods: This retrospective study involved a chart audit of individuals with SCI who underwent two consecutive urodynamic studies between April 1, 2015 and April 1, 2018. After adding 50 mg of mirabegron once a day to the pre-existing antimuscarinic therapy for a period of, at least 6 months, the following variables were analyzed: change in cystometric capacity, change in bladder compliance, change in maximal detrusor pressure, change in reflex volume, and presence of significant leakage during filling cystometry.
