Abstract
Vesicourethral static pressure recordings were attempted in patients with detrusor urethral sphincter dyssynergia. The technique consisted of recording vesicourethral pressures at successive points, commencing in the lower segment of the bladder during micturition. A small catheter with side holes was used for this purpose and static (lateral) pressure profile recordings were attempted during voiding. Successful static pressure recordings were obtained only in those patients who could expel urine as uninterrupted stream. Patients who could not void or those who could void only with interrupted stream have demonstrated profile patterns that required careful interpretation. The accuracy of urodynamic interpretation also depended on careful clinical evaluation and awareness of the built-in artifacts of the technique.
