We studied the normal anatomy of distal ureter and ureterovesical junction using ELUS. Materials and Methods: An assessment of in vitro ELUS ureteric images undertaken at 1 mm. intervals from 8 fresh human cadaver pelvis blocs of bladder and distal ureter were compared with findings of serial histological sections of the same specimens (stained for cholinesterase isoenzymes) to assess the degree of correlation. Computer-assisted 3D reconstructions were made. Results: The different components (ureteric, detrusor and periureteric tissue) of the UVJ could be identified on the basis of echogenicity and form, but differentiation between the respective muscle layers in the wall of the ureter or of the detrusor was not possible. Nevertheless, ureteric volume measurements and an assessment of transmural ureteric length and the angle of passage through the bladder wall were possible. Conclusions: ELUS is able to differentiate between the ureteric and detrusor muscle and the UVJ gross anatomy can be reconstructed. ELUS technology, however, fails to differentiate between individual muscular layers of the ureter or the detrusor. Further improvement in ELUS is mandatory.
