Urodynamic Findings of The Patients with Parkinson’s Disease: A Single Tertiary Center Results

Abstract

Objective :In Parkinson’s disease (PD), lower urinary tract symptoms (LUTS) are common with a prevalence ranging from 25% to 57%. Patients who are resistant to medical treatment for LUTS may require urodynamic examination and pressure flow study (UD-PFS) to better comprehend the bladder's dynamics. To be able to comprehend the pathophysiology of LUTS, UD-PFS examinations should be performed. In this study, the demographics and clinical properties of PD patients were presented along with their UD-PFS examinations. Method : The data of 155 patients with PD followed up between 2010-2020 were retrospectively analyzed. UD-PFS was applied to 42 PD patients resistant to medical treatment of LUTS. Patients' demographic and clinical data with their UD-PFS findings were studied separately. Result : Twenty-eight of the patients underwent UD-PFS were male, and 14 were female. In UD, the first urinary sensation was 86.00±68.77cc, and the maximum cystometric capacity was 322.07±194.25cc. Sixteen patients had a hypo-compliant bladder, 25 (59.5%) had a normo-compliant bladder. In PFS, Q max and peak detrusor pressure during voiding were 12.72±10.08 mL/sec and 43.93±15.56 cm-H2O, respectively. Stress-type urinary incontinence was detected in 6 (15%) of the patients. When evaluating the detrusor activity, neurogenic detrusor overactivity in 18 (44%) patients, detrusor areflexia in 8 (19%) and normal UD-PFS in 16 (22%) patients. Conclusion: The majority of the patients presented with neurogenic detrusor overactivity accompanied by diminished bladder capacity and hypersensitivity. In the selected PD patients who are resistant to medical treatment with LUTS clinics, UD-PFS provides useful scientific information about the LUTS clinics of patients and may be helpful in treatment management.
