To evaluate the macroscopic and microscopic anatomy of the human ureterovesical junction to clarify the mechanism of anti-reflux function.
Performed bidirectional macro- and microscopic dissections on 8 adult and 2 fetal human bladders.
The trigonal detrusor muscle consists of three triangular layers, while the ureters are loosely enveloped by a fibromuscular sheath predominantly of bladder origin that facilitates oblique mobility.
Most ureteral muscle fibers fan out to terminate at the bladder mucosa or interlace with fibers from the contralateral ureter rather than forming a classic ureteral sphincter.
The intricate muscular organization provides an active anti-reflux muscular mechanism rather than a traditional sphincter-based closure.

Implication

Cadaveric dissection study demonstrates a complex multi-layered muscular arrangement at the ureterovesical junction in human bladders, suggesting an active muscular anti-reflux mechanism.
