We report a case of a 5.8 cm. right renal artery aneurysm diagnosed intact 8 weeks post partum. Rupture of a renal arterial aneurysm during pregnancy is a rare but well described catastrophic event. There are no previous reports of an intact renal artery aneurysm diagnosed either ante partum or post partum. To our knowledge, this also represents the largest reported renal artery aneurysm. The aneurysm was repaired successfully with kidney salvage and closure of the fistulous connection to the renal vein.
A study was done in 21 men to identify individuals with venous leakage as a cause of impotence. Combined pressure flow measurement and cinecavernosography were performed before and after the injection of papaverine into the corpora. After papaverine injection, erections and/or higher pressures occurred at lower flow rates in all the men. The venous drainage of the corpora decreased or disappeared in most subjects while the corpora became larger and contained more contrast material. The findings suggest that an active venous obstructive mechanism is important during erection, can be induced by the administration of papaverine, and should be evaluated in impotent men.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
