摘要:

The uroflowmetry has value (1) as a screening procedure in bladder outlet diseases, and (2) in assessing results of treatment. The results of measurement depend: (1) on the circumstances of micturition; (2) on the bladder volume, and (3) on how far the patient is cooperative. The interpretation of measurements must be related not only to maximum flow and micturition time, but also to a specific micturition pattern. As an isolated method the uroflowmetry has limitations. The value of this procedure may increase by pressure measurements during micturition. However, caution should be exercised in interpreting a resistance factor. Extensive information is presented by simultaneous cine-pressure-flow measurement. Additional urodynamic procedures, especially the urethra pressure profile, are of no value in bladder outlet obstructions.

摘要:

The present study was undertaken to determine if urinary protein can produce urinary stones and what types of protein have such an effect. Normal human serum was fractionated first with ammonium sulfate and then with DEAE-cellulose. The stone-forming action of each fraction was estimated by calculating their ability to alter the sedimentation rate and ξ-potential of a calcium carbonate suspension. Finally, the proteins in each fraction were identified by cellulose acetate electrophoresis. The most marked aggregating and precipitating effect on a CaCO3 suspension was observed with a mixture of proteins of α1 -globulin and albumin fractions. However, β- and γ-fractions had little aggregating effect on the CaCO3 suspens

摘要:

Urodynamic investigation consists of evaluation of detrusor stretch responses, muscle strength and motor activities. The electrosensitivity test is the only method to evaluate mucosal sensory threshold of exteroceptive receptors in urinary bladder and posterior urethra thus checking integrity of sensory reflex arcs. A constant current square wave pulse of 0.5 msec duration and 10 msec interval is used with increasing amplitude from 0 to 25 mA until the patient registers sensation. Skin electrosensitivity is tested to start with, then perception threshold of urinary bladder and posterior urethra is recorded. Sensory deficits after segmental sacral nerve lesions or after peripheral nerve injuries postoperatively can be quantitated in terms of milliamperes. The urgency syndrome in adult women is characterized by a low perception threshold in the posterior urethra (below 1 mA) while the bladder electrosensitivity is within normal range (3–10 mA

摘要:

A newly available compact urodynamic set-up is presented herein, consisting of a 2-channel CO2 pressure recording unit with flow registration. Flow, bladder and rectal pressure recording are considered the minimal requirements for obtaining sufficient information on functional changes of the lower urinary tract.

摘要:

Intravesical instillation of formalin in a patient with transitional cell carcinoma of the bladder and radiation cystitis was followed by acute renal failure due to acute tubular necrosis. Formic acid, which is a metabolic product of formalin, has been postulated as the pathogenetic agent responsible for acute tubular necrosis.
