Summary
Post Void Residual Volume (PVRV) is common in older adults and linked to infections and poor mobility. Ultrasound bladder scans are effective for screening PVRV in geriatric wards.
Area of Science:
- Geriatric Medicine
- Urology
- Diagnostic Imaging
Background:
- Post Void Residual Volume (PVRV) is a significant risk factor for urinary tract infections, incontinence, and renal insufficiency in the elderly.
- High PVRV is associated with advanced age, immobility, constipation, and various neurological and metabolic diseases.
Purpose of the Study:
- To determine the prevalence of high Post Void Residual Volume (PVRV) in geriatric patients.
- To identify risk factors associated with elevated PVRV in this population.
Main Methods:
- A prospective study involving 100 geriatric patients admitted to a ward.
- Ultrasound bladder scans (UB) were performed three times within the first two days of admission.
- Data collected included age, gender, cognitive function (MMSE), functional status (Barthel score), and presence of bacteriuria, incontinence, and constipation.
Main Results:
- Out of 100 patients (mean age 83.9 years), 14 patients had PVRV > 150 ml, and 48 had PVRV < 100 ml.
- Significant correlations were found between high PVRV (>150 ml) and bacteriuria (p=0.04) and lower Barthel scores (p=0.03).
- Prevalence of constipation was 29%, urinary incontinence 41%, and bacteriuria 37%.
Conclusions:
- Post Void Residual Volume (PVRV) is prevalent in geriatric populations.
- High PVRV is positively correlated with bacteriuria and reduced functional performance.
- Ultrasound bladder scanning is a feasible screening method for PVRV in geriatric settings.

01:15Respiratory Volumes
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

01:19Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:22Respiratory Volumes and Capacities
The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
