The ureteral pressure profile: an experimental study in canine ureters. 1978

E Bruijnes

In 10 anesthesized mongrel dogs ureteral pressure profiles were obtained with two types of high density polyethylene catheters. During the profilometry X-ray image intensification was performed. The data obtained from both ureters and also from both types of catheters did not show any statistically significant difference (p less than 0.05). Near the uretero-vesical junction a statistically significant biphasically shaped graph with mean pressures of 89.2 +/- 5.25 and 81.7 +/- 8.43 (SEM) mm Hg for the proximal and distal top, respectively, was seen (p less than 0.05). This phenomenon corresponds with the morphology, as mentioned in literature and as investigated in this experiment by X-ray photographs at post-mortem specimens.
