  • Title: Videocystography with synchronous detrusor pressure and flow rate recordings.
    Author: Arnold EP, Brown AD, Webster JR.
    Journal: Ann R Coll Surg Engl; 1974 Aug; 55(2):90-8. PubMed ID: 4846340.
    Abstract:
    The addition of pressure and flow rate recordings to conventional cystourethrography is relatively inexpensive in terms of cost and of radiologist's time, each investigation requiring approximately half an hour.The value of this investigation in males lies in assessing the severity and site of outlet obstruction, particularly when the prostate is not clinically enlarged. Its value in demonstrating detrusor instability in cases of obstruction and in patients with post-prostatectomy problems is discussed. It is essential to the adequate assessment of sphincter mechanisms in both males and females. The particular importance of this in the female lies in the poor results of routine surgery for incontinence where this is due to detrusor instability.Finally the importance in neurological patients of a urodynamic evaluation of continence mechanisms and voiding dysfunction, both as a preliminary assessment and as a guide to the efficacy of treatment, is outlined.Various criticisms of the technique are reviewed and appropriate rebuttals provided.
