Under basal conditions no pelvic pressure increase was observed during detrusor contraction or other alteration of lower urinary tract pressure. However, after the flow in the upper tract was increased by oral water load, intravenous furosemide or direct pelvic perfusion, pelvic pressures were markedly elevated and reflected accurately any change in intravesical pressure. Under such conditions, pelvic pressures frequently exceeded 40cm. water. These observations provide an explanation for the increasing size of the upper tract and a clarification of the mechanism whereby renal function might gradually deteriorate in these patients. © 1988 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByGHANEM M, WOLFFENBUTTEL K, DE VYLDER A and NIJMAN R (2018) LONG-TERM BLADDER DYSFUNCTION AND RENAL FUNCTION IN BOYS WITH POSTERIOR URETHRAL VALVES BASED ON URODYNAMIC FINDINGSJournal of Urology, VOL. 171, NO. 6 Part 1, (2409-2412), Online publication date: 1-Jun-2004.Koo H, Macarak E, Zderic S, Duckett J, Snyder H and Levin R (2018) The Ontogeny of Bladder Function in the Fetal CalfJournal of Urology, VOL. 154, NO. 1, (283-287), Online publication date: 1-Jul-1995.Hulbert W, Rosenberg H, Cartwright P, Duckett J and Snyder H (2018) The Predictive Value of Ultrasonography in Evaluation of Infants with Posterior Urethral ValvesJournal of Urology, VOL. 148, NO. 1, (122-124), Online publication date: 1-Jul-1992.
