ABSTRACT
OBJECTIVE: The present study sought to investigate lower urinary tract symptoms and urodynamic and cystometric findings in Parkinson disease (PD), dementia with Lewy bodies (DLB), and Alzheimer disease (AD). METHODS: Included were patients with frequency, urgency, incontinence, and nocturia, without major bladder outflow obstruction. The protocol comprised physical examination, urine analysis, prostate specific antigen, 24-hours frequency of micturition, mean voided volume (MVV), free flow before instrumentation (Qmax(before)), post-void residual volume (PVR), and cystometry. RESULTS: Fifteen patients with DLB and PD and 16 patients with AD were examined. MVV, PVR, Qmax(before) and with transurethral catheter, cystometric bladder capacity, and detrusor pressor at maximum flow were similar in the three groups and corresponded to values of the general elderly population. Urge episodes and urge incontinence were observed in 93 and 53% of the patients with DLB, 53 and 27% of the patients with PD, and 19 and 12% of the patients with AD, and detrusor overactivity in 92% of the patients with DLB, 46% of the patients with PD, and 40% of the patients with AD. CONCLUSIONS: Urgency and urge incontinence suggest detrusor overactivity, which was more prevalent in dementia with Lewy bodies than in Parkinson disease and Alzheimer disease, whereas mean voided volume, free flow, cystometric bladder capacity, and detrusor pressor were similar in the groups. Frequency of micturition could not be reliably assessed in patients with dementia.

Bladder substitution in women with transitional cell carcinoma (TCC) is not a universally accepted procedure. There are many concerns, one of which is the potential risk of metachronous and synchronous urethral transitional cell carcinoma involvement. Another concern is that voiding dysfunction may be more frequent than in male patients. The numbers of female patients who have had this procedure are still small, and follow-up data are relatively brief. Thus, the true role for orthotopic bladder substitution in the female is still being evaluated. This paper reviews the data on this type of surgery in women, with emphasis on urethral TCC risk and on voiding dysfunction. Early results from a number of institutions are encouraging, particularly in correctly selected patients. Based on more than 15 years experience in an albeit small number of patients, we believe that if there is a functional external sphincter and tumor margins can be safely cleared, this form of surgery offers patients the best opportunity to preserve quality of life following cystectomy.
