Amongst other features of bladder physiology, the mechanics of cyclic filli
ng and emptying make the blood supply of the bladder unique with respect to
other organs of the body. Blood vessels are required to lengthen and short
en, whilst maintaining sufficient perfusion of the smooth muscle. Interrupt
ion of the blood supply may result in ischaemia and, ultimately reperfusion
, resulting in bladder pathologies. The blood flow is also likely to be aff
ected by factors such as increased intra-abdominal pressure. In this articl
e, several features of the blood supply to the bladder - and also the ureth
ra - are discussed.
