ABSTRACT
INTRODUCTION:
Lewy Body Dementia (LBD) is a Parkinsonian disorder which often leads to Lower Urinary Tract Symptoms (LUTS), especially an Overactive Bladder (OAB). There have been few LBD related LUTS depictions in the literature, which is why we did this retrospective study.METHODS:
Retrospective single institution study.RESULTS:
Nineteen patients with confirmed LBD diagnosis were found, (63% of men, mean age 74 years old). The main symptom was OAB (100% of patients) with frequent stress urinary incontinence (94%) associated with detrusor overactivity (93%) with pressure elevation (79%). Voiding difficulties were found in 16% of medical interviews, and in 53% of urodynamics. In total, 92% of patients complained of constipation, with 44% suffering from fecal incontinence.DISCUSSION:
LBD is characterized by alpha-synuclein aggregates in the cerebral cortex, thus explaining associated cognitive impairment. The most commonly found LUTS is stress incontinence. We also found voiding difficulties in smaller proportion, sometimes associated with prostatism. Topographically, these symptoms could be explained by alpha-synuclein aggregates in the frontal and temporal cortex and the pons. Anorectal disorder and sexual dysfunction were frequently associated. Urological complications are scarce in this population, screening is focused in increasing quality of life, and the possibility to discriminate the different types of Parkinsonisms.CONCLUSION:
OAB is the most common lower urinary tract symptom in LBD often associated with detrusor overactivity, and less frequently voiding difficulties sometimes associated to prostatism. LEVEL OF EVIDENCE 3.Key words
