Pacemakers in the upper urinary tract.
BACKGROUND Pacemakers in upper urinary tract (UUT) are still under study. AIM We reviewed the role of some cells that seem to be involved in the propulsion of urinary bolus from UUT to the bladder. MATERIALS & METHODS We focuses on evaluating studies on the mechanisms by which the UUT propels urine to the bladder via pacemaker cells. RESULTS Electric active pacemaker cells generate pyelou...
متن کامل6 Purinoceptors in the upper urinary tract
There is now abundant evidence for ATP acting as an extracellular signalling molecule. Receptors for ATP have been cloned and characterised, including seven P2X ionotropic and eight P2Y metabotropic receptor subtypes, as well as four subtypes of P1 receptors sensitive to adenosine, a breakdown product of ATP. P2 purinoceptor subtypes are expressed on ureteral smooth muscle, urothelium and blood...
متن کاملPacemaker activity in the upper urinary tract.
Ureteral peristaltic activity begins with the origin of electrical activity at pacemaker sites. These sites are located in the proximal portion of the urinary collecting system. The 'atypical' smooth muscle cells at these sites fire 'pacemaker' potentials at a frequency higher than the 'driven' action potentials recorded from typical smooth muscle cells. In contrast to typical smooth muscle cel...
