  • Frederick C. McLellan and clinical cystometrics. [Historical Article]
    Urology. 1998 Jan; 51(1):168-72.Bloom DA, Uznis G, … McGuire EJ
  • Precise analysis of lower urinary tract function was an unfulfilled dream only a century ago. By the late 19th century, water manometers and plethysmographs were utilized to measure bladder pressures. In the early 1900s, Rose developed a cystometer that was later improved by Munro. In 1938 Frederick C. McLellan, active in clinical research under Reed Nesbit at the University of Michigan, was the …
  • Simple standing incremental cystometry as a screening method for detrusor instability. [Journal Article]
    Obstet Gynecol. 1991 Mar; 77(3):453-7.Sand PK, Brubaker LT, Novak T
  • One hundred consecutive neurologically normal women complaining of urinary incontinence underwent standing incremental retrograde medium-fill water cystometrograms on two different days followed by sitting and standing continuous retrograde medium-fill water urethrocystometry on a third visit between November 1987 and February 1989. Studies were done to assess the reproducibility, sensitivity, sp…
  • [Experiences in treatment of urinary incontinence in the female by electrostimulation]. [Journal Article]
    Zentralbl Gynakol. 1987; 109(20):1240-4.Zsolnai B, Pajor A, Matányi S
  • Electrostimulation-treatment was carried out in 47 female patients suffering from urinary stress incontinence. A special electrode-pair was applicated in the vagina under the bladder neck. The electrostimulation lasted for 8 hours daily through 3 to 8 days on one hand, and on the other hand for 24 hours 3 to 5 times successively. In order to specify the cases and to perform the urodynamics a urof…
  • Carbon dioxide uroflowmetry. [Journal Article]
    J Urol. 1979 Oct; 122(4):512-4.Corlett RC, Roy S
  • A method using pneumatic compression to determine flow rate is described. The procedure is best suited for physicians using carbon dioxide instrumentation for a urodynamic assessment of patients since the carbon dioxide cystometer is readily converted to a uroflowmeter. Values obtained with this method are similar to values reported in the literature using other techniques. When voided volumes ar…
  • Detrusor muscle and sphincteric response to anorectal stimulation in spinal cord injury. [Journal Article]
    Arch Phys Med Rehabil. 1979 Jun; 60(6):269-72.Rodriquez AA, Awad E
  • Twelve patients with spinal cord injuries were studied to determine whether the anal sphincter could be used as an index of urethral sphincter activity and to determine the bladder and striated sphincter response to anal and rectal stimulation. Electromyogram (emg) needle electrodes were placed in the external urethral sphincter, external anal sphincter and levator ani. The output of a cystometer…
  • A carbon dioxide flowmeter. [Journal Article]
    J Urol. 1977 Dec; 118(6):1035-6.Raz S, Martin J, Kaufman JJ
  • A simple and inexpensive uroflowmeter has been designed that uses a common carbon dioxide cystometer. The patient voids urine in a specially designed container connected at the bottom of the carbon dioxide source in the cystometer. After proper calibration (500 cc fluid for a 20 mm. deflection in the paper) the patient is asked to void while carbon dioxide flows through the container and the pape…
  • Recording of vesical voiding pressure by means of CO2-perfusion. [Journal Article]
    Br J Urol. 1977 Nov; 49(6):531-5.Tscholl R, Lenzi A
  • By means of a CO-2-cystometer, carbon dioxide is introduced through a urethral catheter (F5) into the full urinary bladder while the subject is urinating around the catheter. A reproducible pressure curve can be recorded. The pressure values measured by CO2-perfusion correlate very well with those measured simultaneously by a conventional fluid method. It can be statistically demonstrated that th…
  • Carbon dioxide-urethral pressure profile in female incontinence. [Journal Article]
    J Urol. 1977 Jun; 117(6):765-9.Raz S, Kaufman JJ
  • Herein we describe a method to assess urethral dynamics in women with urinary incontinence, using a carbon dioxide cystometer. The parameters evaluated are the maximum urethral closing pressure, functional urethral length, active continence, transmission of intra-abdominal pressure to the urethral pressure and changes when patients are in the supine and erect positions.
  • Carbon dioxide urethral pressure profile. [Journal Article]
    J Urol. 1976 Apr; 115(4):439-42.Raz S, Kaufman JJ
  • In an evaluation of patients with lower urinary tract symptoms, particularly incontinence, the role played by the urethra is crucial. One of the most important methods of evaluation of urethral dysfunction is the urethral pressure profile. From among the many simple and more sophisticated methods of urethral pressure profile measurements we have chosen to describe a simple office procedure and a …
    Can Med Assoc J. 1965 Aug 21; 93:353-7.SPRING WB
  • Bladder function during sleep was studied by the use of a cystometer which recorded detrusor contractions and intravesical pressure as urine accumulated in the bladder during diuresis. The cystometrographic tracing was obtained while the patient was awake. A detrusor contraction can occur during sleep. Results of such studies on five patients are presented, with photographs of representative cyst…
