In 27 patients with clinically identified idiopathic left varicocele, a retrograde venography and a combined pressure measurement in the vena cava, vena renalis and vena spermatica was performed. During Valsalva maneuver the pressure values increased. We could not confirm increased pressure values in the left renal vein dependent on the patient's position. There were no increasing pressure gradients between vena renalis and vena cava in erect position. Therefore an elevated pressure in the left renal vein and especially the 'upper nutcracker' does seem to be of at least limited importance for the pathogenesis of idiopathic varicocele.
对27例临床确诊为特发性左侧精索静脉曲张的患者进行了逆行静脉造影，并对腔静脉、肾静脉和精索静脉进行了联合压力测量。在瓦尔萨尔瓦动作期间，压力值升高。我们无法证实左肾静脉压力值随患者体位而升高。直立位时肾静脉和腔静脉之间不存在压力梯度增加。因此，左肾静脉压力升高，尤其是“胡桃夹”现象，对于特发性精索静脉曲张的发病机制似乎至少只有有限的重要性。
