In addition to gravity-dependent position, we suppose that other particular anatomic features may be important in the retention of stone debris in lower calices after extracorporeal shockwave lithotripsy (SWL). We analyzed the inferior-pole collecting system anatomy in 146 three-dimensional polyester resin corrosion endocasts of the pelviocaliceal system. In 74% of the cases, there was an angle of greater than 90 degrees formed between the lower infundibulum and the renal pelvis, and in 26%, the angle was 90 degrees or less. In 60%, there was a lower infundibulum 4 mm or larger in diameter. The inferior pole was drained by multiple calices disposed in two rows in 57% of the cases and by one midline caliceal infundibulum in 43%. We believe that the physician must appreciate these anatomic features when considering SWL to treat calculi located in lower calices.
除了重力依赖位置外，我们推测其他特定的解剖学特征可能在体外冲击波碎石术（SWL）后结石碎片滞留在下肾盏中起重要作用。我们分析了146个肾盂肾盏系统的三维聚酯树脂腐蚀铸型中下极集合系统的解剖结构。在74%的病例中，下漏斗部与肾盂之间形成的角度大于90度，在26%的病例中，该角度为90度或更小。在60%的病例中，下漏斗部直径为4毫米或更大。57%的病例中，下极由两排排列的多个肾盏引流，43%的病例中由一个中线肾盏漏斗部引流。我们认为，医生在考虑用SWL治疗位于下肾盏的结石时必须了解这些解剖学特征。
