Functional incontinence is a condition related to dementia and/or gait disturbance interfering with independent toileting skills. "

    ABSTRACT: Idiopathic normal pressure hydrocephalus (INPH) is a syndrome of ventriculomegaly, gait impairment, cognitive decline and incontinence that occurs in an elderly population prone to many types of comorbidities. Identification of the comorbidities is thus an important part of the clinical management of INPH patients. In 2011, a task force was appointed by the International Society for Hydrocephalus and Cerebrospinal Fluid Disorders (ISHCSF) with the objective to compile an evidence-based expert analysis of what we know and what we need to know regarding comorbidities in (INPH). This article is the final report of the task force. The expert panel conducted a comprehensive review of the literature. After weighing the evidence, the various proposals were discussed and the final document was approved by all the task force members and represents a consensus of expert opinions. Recommendations regarding the following topics are given: I. Musculoskeletal conditions; II. Urinary problems; III. Vascular disease including risk factors, Binswanger disease, and white matter hyperintensities; IV. Mild cognitive impairment and Alzheimer disease including biopsies; V. Other dementias (frontotemporal dementia, Lewy body, Parkinson); VI. Psychiatric and behavioral disorders; VII. Brain imaging; VIII. How to investigate and quantify. The task force concluded that comorbidity can be an important predictor of prognosis and post-operative outcome in INPH. Reported differences in outcomes among various INPH cohorts may be partly explained by variation in the rate and types of comorbidities at different hydrocephalus centers. Identification of comorbidities should thus be a central part of the clinical management of INPH where a detailed history, physical examination, and targeted investigations are the basis for diagnosis and grading. Future INPH research should focus on the contribution of comorbidity to overall morbidity, mortality and long-term outcomes.

    ABSTRACT: Amyotrophic lateral sclerosis (ALS) related disorders are considered to be uncommon. We hypothesize that urinary dysfunction may occur in ALS patients in the context of spasticity of pelvic floor musculature. We recorded data on 54 subjects with ALS. All subjects were evaluated with ALSFRS and M-Ashworth Scale for lower limbs. Bladder scan procedure was performed to asses post void residual (PVR) in all subjects. Forty-one percent of subjects were symptomatic for urinary disorders and 35% of subjects had a PVR > 50 ml. Linear correlation was found between PVR and ALSFRS with a R(2) 0.95 and p = 0.025; a linear correlation was also noted between PVR and lower limbs Ashworth Scale. We conclude that urinary retention is common in ALS. Urological evaluation is indicated in ALS patients with prominent spasticity.

    ABSTRACT: BACKGROUND: In a previous observational study, thoracic epidural analgesia (TEA) after open renal surgery resulted in clinically relevant postvoid residuals (PVRs). This study aimed to investigate the individual contribution of epidurally administrated drugs and surgery in bladder dysfunction. METHODS: In this single-center, parallel-group, randomized (computer-generated list), double-blind superiority trial, 40 patients undergoing open renal surgery were equally allocated to receive epidural bupivacaine (0.125%) alone or with fentanyl (2 µg/ml). Patients underwent urodynamic investigations before TEA and during TEA preoperatively and postoperatively. Primary outcome was the difference (Δ) in PVR between before TEA and postoperatively during TEA. Secondary outcomes were changes in detrusor pressure at maximum flow rate, bladder compliance, and ΔPVR between different time points. RESULTS: Median ΔPVR (ml) from baseline to postoperatively was 180 (range, -85 to 645; P = 0.001) in the bupivacaine group and 235 (range, 0-580; P value less than 0.001) in the bupivacaine/fentanyl group, with no difference between groups (95% confidence interval, -167 to 103; P = 0.634). Detrusor pressure at maximum flow rate (cm H(2)O) from baseline was more pronounced in the bupivacaine/fentanyl than that in the bupivacaine group preoperatively (-10; range, -64 to -2; P value less than 0.001 vs. -3; range, -35 to 13; P = 0.397) (P = 0.045) and postoperatively (-18; range, -64 to 0; P value less than 0.001 vs. -12; range, -34 to 22; P = 0.006) (P = 0.135). Surgery did not affect PVRs, but a decreased bladder compliance was observed in both groups. No adverse events occurred. CONCLUSIONS: Thoracic epidurally administrated bupivacaine resulted in clinically relevant PVRs based on impaired detrusor function. The addition of fentanyl enhanced this effect without generating greater PVRs. After surgery, the voiding phase was not further impaired; however, bladder compliance was decreased.
