Urinary bladder volume tracking using a Kalman filter

Medical & Biological Engineering & Computing, 2005
This study introduced the Kalman filter procedure for tracking urinary bladder filling from intermittent bladder volume measurements taken by an ultrasonic bladder volume monitor. The Kalman filter was based on a double integrator as a model for the bladder filling process between micturitions and included a procedure to reset the filter in the event ...

The Use of Frequency/Volume Charts to Assess Urinary Incontinence

Physical Therapy Reviews, 2000
When evaluating any treatment modality for incontinence, it is essential that the severity of incontinence is measured. There are various ways of determining the severity of incontinence, such as quality-of-life questionnaires and pad tests. The use of frequency/volume charts to collect data concerning voiding patterns was first introduced in 1974 ...

Thyroid volumes and urinary iodine in German school children

Experimental and Clinical Endocrinology & Diabetes, 2001
Several recently published investigations showed a significant improvement in the iodine supply of the German population, but so far Germany is still considered an iodine deficient country. However most of the studies presented do not meet the epidemiological criteria established by WHO, UNICEF and ICCIDD and may therefore suffer from a selection bias ...

Residual Urinary Volume and Urinary Tract Infection, A Life Threatening Illness: A Case Report

Journal of Environmental Pathology, Toxicology and Oncology, 2010
Multiple Sclerosis (MS) is an inflammatory disease that demyelinates the central nervous system causing progressive disability. The urodynamics of MS patients is an important consideration because these patients are susceptible to acute urinary bladder retention associated with a high fever.

Nomograms of total renal volume, urinary bladder volume and bladder wall thickness index in 3,376 children with a normal urinary tract

Pediatric Radiology, 2006
We have previously shown that urinary bladder volume index (BVI = length x width x depth of bladder) and bladder volume wall thickness index (BVWI = BVI at full bladder/average bladder wall thickness) are useful indicators of bladder dysfunction in children with enuresis and urinary tract infection. These indices show a good correlation with urodynamic

Adjustment of Urinary Concentration to Urinary Volume in Relation to Erythrocyte and Plasma Concentrations: An Evaluation of Urinary Heavy Metals and Organic Substances

Archives of Environmental Health: An International Journal, 1986
The effects of urinary volume on adjusted and nonadjusted urinary excretion of 11 heavy metals and organic substances were examined in relation to plasma and erythrocyte concentrations in 19 metal workers under conditions of water restriction and loading. Blood lead concentrations in these workers ranged from 25 to 59 micrograms/dl.

Effects of Chlorpromazine on Fear-Motivated Behavior, Urinary Cortisol, Urinary Volume and Heart Rate in the Dog

Psychological Reports, 1976
Several doses of chlorpromazine (6.25, 12.5, 25.0 mg) were administered to dogs while they were subjected to a Sidman nondiscriminated avoidance schedule which contained 7 conditioned stimuli-unavoidable shock (CS-US) pairings. The drug consistently reduced baseline response rate and enhanced shock rate.

Monitoring urinary bladder volume and detecting post‐operative urinary retention in children with an ultrasound scanner

Acta Anaesthesiologica Scandinavica, 2005
Background:  Post‐operative urinary retention (PUR) is associated with a risk of over‐distension and permanent detrusor damage. The prevention of PUR by routine catheterization may increase the risk of urinary tract infection. Post‐operative monitoring of the bladder volume is a reliable method in adults, but has not been evaluated for reliability in ...

A study of circadian rhythmicity in urinary volume excretion.

2012
This research investigated the presence of circadian rhythmicity in urinary volume excretion. A retrospective study medical record was completed to investigate the occurrence of rhythmic variation. Twenty-five subjects were utilized to gather urinary volume data, collected at either four- or six-hour intervals.

Cell volume regulation in frog urinary bladder.

Federation proceedings, 1985
We have studied the problem of cell volume homeostasis in toad and frog urinary bladder by using electrophysiological measurements and an optical measure of cell volume. After osmotically induced swelling, urinary bladder cells spontaneously regulate their volume through a net loss of potassium, chloride, and water.
