PURPOSE We used urodynamics and perineal ultrasound to assess the function and morphology of the urethral sphincter and detrusor muscle in the evaluation of dysfunctional voiding in female patients with recurrent urinary tract infections. MATERIALS AND METHODS Patients selected for study purposes completed the American Urological Association Symptom Index and underwent multichannel video urod...

Angiotensin (5 ng/kg/min and 50 ng/kg/min) was infused directly into the left renal artery of anesthetized dogs in order to examine its effects on the renal func tion. Urinary volume, creatinine clearance (GFR), PAH-clearance (RPF) and electrolyte excretion were decreased by infusion of angiotensin in a small dose. On the other hand extreme reductions of urinary volume, GFR, RPF and electrolyte...

BACKGROUND Both lower urinary tract dysfunction and urinary symptoms are prevalent in patients with multiple sclerosis (MS). Although the significance of identifying and treating urinary symptoms in MS is currently well-known, there is no information about the real prevalence and therapeutic effect of urinary symptoms in patients with MS. The purpose of this study was to analyze the major sympt...

Savage, M. O., Wilkinson, A. R., Baum, J. D., Roberton, N. R. C. (1975). Archives of Disease in Childhood, 50, 709. Frusemide in respiratory distress syndrome. The effect of frusemide on urinary volume, urinary sodium excretion, and urinary calcium excretion in 7 premature infants with severe respiratory distress syndrome (RDS) has been studied. The results are compared with similar measurement...

OBJECTIVES To evaluate the value of performing urodynamic investigations in the assessment of women with a history of pure stress urinary incontinence (SUI). METHODS Consecutive women with lower urinary tract symptoms were studied retrospectively. Urinary symptoms were determined from the frequency-volume chart and symptom section of the King's Health Questionnaire. Only women with pure SUI s...

Serial determinations of plasma volume and urinary sodium excretion were determined during saluresis in 20 hypertensive patients. Although the diuretics produced a decrease in plasma volume and an increase in urinary sodium excretion in all patients, there was no direct relationship between the decrease in plasma volume and the fall in arterial pressure. Concomitant administration of dextran so...

Urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. In this study, solid phase extraction was appropriately conditioned with regard to sample pH, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. Octadecyl silica cartridge (C<su...

1. In six healthy volunteer subjects polydipsic water loading significantly increased urine volume from 1203 +/- 242 (SEM) to 5072 +/- 320 ml/24 h (P less than 0.001) with a significant decrease in urinary osmolality. This increase in urine volume by more than fourfold was associated with a slight increase in urinary excretion of prostaglandin E2 from 466 +/- 66 to 1017 +/- 174 pmol/24 h (P = 0...
