Comparison of urodynamics between ischemic and hemorrhagic stroke patients; can we suggest the category of urinary dysfunction in patients with cerebrovascular accident according to type of stroke?

AIMS: The aim of this study is to compare the urodynamic parameters in ischemic and hemorrhagic stroke patients with bladder dysfunction.

MATERIALS AND

METHODS

We retrospectively reviewed medical records such as computed tomography (CT) or magnetic resonance imaging (MRI) and urodynamic study and identified 84 cases among 150 stroke patients underwent urodynamic test due to lower urinary tract symptoms (LUTS) from June 2003 to May 2008. Exclusion criteria are diabetes mellitus (DM) cystopathy, previous pelvic surgery, spinal cord injury, benign prostate hyperplasia (BPH), and other neurologic etiology.

RESULTS

Among analyzed variables of urodynamic study, total bladder capacity, postvoid residual urine volume and bladder compliance have a significant value between ischemic and hemorrhagic stroke group (P = 0.004, P = 0.017, P = 0.007). Ischemic group have detrusor overactivity (DO) (70.7%), detrusor underactivity (DU) (29.3%), and hemorrhagic group have DO (34.6%), DU (65.4%). (P = 0.003).

CONCLUSIONS

Evaluation of the stroke type may be helpful in the determination of the type of urinary dysfunction and in deciding the appropriate bladder management. The urodynamic study, however, is essential to manage LUTS in stroke patients.
