The effect of bladder function on the dynamics of the ureterovesical junction.
Upper tract perfusion studies in suspected ureterovesical junction obstruction should always be performed with measurement of intravesical pressure and with variation in bladder volume. Obstruction observed with increasing bladder volumes may be related to a non-compliant bladder wall, mechanical obstruction at or near the junction itself or a combination of both factors.
