title: [Effect of acute distension of the bladder on blood flow and the resistance of the peripheral vessels].
abstract: The effects of acute, rapid distention of the urinary bladder on the arterial pressure, blood flow and peripheral resistances were studied on dogs and an attempt was made to elucidate the mechanisms of cardiovascular responses observed. In 15 dogs with intact nervous system the arterial blood pressure and blood flow of the femoral, brachial and renal arteries were recorded and the vascular resistances were calculated during an increase of the intra-bladder pressure. Acute distention of the bladder, in the dog, increases arterial blood pressure by 10,25%, the vascular resistance of the femoral and renal vascular bed increases while that of the brachial artery is slightly reduced.
