Results were as follows :
(1) There are four peripheral nerves which conduct the pain-sensation from the upper ureter to the brain. These are splanchnic nerve, posterior rami of the sacral spine and afferent fibre of the aortic adventitia.
(2) The splanchnic nerve mainly conducts the contructing stimuli but aortic adventitia only conducts it in the case of stronger stimuli was given, and both concerned to the pain sensation. The vagus nerve worked as a conducting path-way of the pain during only one phase of dilation exitment, but posterior rami workes during both of contructing and dilating stimuli were given and these were considered to not concerned to the painsensation.
(3) Peripheral acceptor in the pelvis and ureter contained scanty of vagus nerve's element, whereas it contained abundant of splanchnic nerve's eIement.
(4) Generally speaking, the pain sensations in the pelvis and ureter were weaker than the other viscerae. Pain sensation of the ureter is stronger than the petvis. These are considered to be due to the action of the splanchnic nerve and the aortic adventitial nerve.
(5) Development of the pain sensations in the case of ureteral calculus may pass through the splanchnic nerve and the aortic adventitia. In this case, responsibility and its duration are higher and longer than the case of ACH or mechanical stimulations.
(6) This experiments greately useful for the clinical practice of the urinaly cakulus or other cases of pain in these areas.
