Popis: Purpose To assess the urodynamic findings in patients with Parkinson disease (PD) with overactive bladder symptoms. Methods We performed a retrospective chart review of all PD patients who were seen in an outpatient clinic for lower urinary tract symptoms (LUTS) between 2010 and 2017 in a single-institution. Only patients who complained of overactive bladder (OAB) symptoms and underwent a video-urodynamic study for these symptoms were included. We excluded patients with neurological disorders other than PD and patients with voiding LUTS but without OAB symptoms. Results We included 42 patients (29 men, 13 women, 74.5±8.1 years old). Seven patients (16.7%) had a postvoid residual (PVR) bladder volume >100 mL and only one reported incomplete bladder emptying. Detrusor overactivity (DO) was found in all 42 patients (100%) and was terminal in 19 (45.2%) and phasic in 22 patients (52.4%). Eighteen patients had detrusor underactivity (DU) (42.3%). Later age of PD diagnosis was the only parameter associated with DU (P=0.02). Patients with bladder outlet obstruction (BOO) were younger than patients without BOO (70.1 years vs. 76.5 years, P=0.004), had later first sensation of bladder filling (173.5 mL vs. 120.3 mL, P=0.02) and first involuntary detrusor contraction (226.4 mL vs. 130.4 mL, P=0.009). Conclusions DO is almost universal in all patients with PD complaining of OAB symptoms (97.1%). However, a significant percentage of patients also had BOO (36.8%), DU (47%), and increased PVR (16.7%) indicating that neurogenic DO may not be the only cause of OAB symptoms in PD patients.
