Urodynamic Findings in Patients with Stroke Having Overactive Bladder Symptoms
1 Department of Physical Medicine and Rehabilitation, Gülhane Military Medical Academy, Turkish Armed Forces Rehabilitation Center, Ankara, Turkey DOI : 10.5152/tftrd.2015.84479 Objective: To determine the effect of the location of the brain lesion on bladder functions by analyzing urodynamic parameters in patients with stroke.

Material and Methods: We retrospectively reviewed the records and urodynamic charts of 51 patients with ischemic and hemorrhagic stroke having an overactive bladder. Stroke localization was made according to the Oxfordshire Community Stroke Project stroke subtypes. Urodynamic parameters that were reviewed included first sensation bladder filling (FSBF), maximum vesical volume, maximum detrusor pressure (MDP), detrusor compliance, residual volume (RV), mean flow rate, voided volume (VV), voiding time, desire to void, and strong desire to void.

Results: Among the 51 patients, 34 were male and 17 were female, with a mean age of 65.8±16.2 years. Thirty-six patients had an ischemic stroke and 15 had a hemorrhagic stroke. Urodynamic studies were performed after a mean of 396.9±713.8 days after the stroke. MDP was associated with gender. MDP was significantly higher in the male group than in the female group (p=0.028). RV was significantly higher in the right hemiplegic group than in the left hemiplegic group (p=0.007). VV was significantly low in the right hemiplegic group than in the left hemiplegic group (p=0.007). Moreover, patients were grouped according to gender and compared in terms of brain lesion laterality. In the right hemiplegic male group, FSBF was delayed, RV was high, and VV was low (p=0.045, p=0.01, and p=0.043, respectively). In the right hemiplegic female group, VV was lower compared with the left hemiplegic female group (p=0.024).

Conclusion: We found significant differences in urodynamic parameters between the right and left hemispheric cerebral infarcts. This suggests that urodynamic findings can be characterized by the laterality of the unilateral hemispheric stroke. However, further studies with a larger number of patients are required.
