Analysis of ureteral length in adult cadavers

Introduction In some occasions, correlations between human structures can help planning surgical intra-abdominal interventions. The previous determination of ureteral length helps pre-operatory planning of surgeries, reduces costs of auxiliary exams, the correct choice of double-J catheter with low morbidity and fewer symptoms, and an adequate adhesion to treatment. Objective To evaluate ureteral length in adult cadavers and to analyze its correlation with anthropometric measures. Materials and Methods: From April 2009 to January 2012 we determined ureteral length of adult cadavers submitted to necropsy and obtained the following measures: height, distance from shoulder to wrist, elbow-wrist, xiphoid appendix-umbilicus, umbilicus-pubis, xiphoid appendix-pubis and between iliac spines. We analyzed the correlations between ureteral length and those anthropometric measures. Results We dissected 115 ureters from 115 adult corpses from April 2009 to January 2012. Median ureteral length didn't vary between sexes or according to height. It was observed no correlation among ureteral length and all considered anthropometric measures in all analyzed subgroups and in general population. There were no significant differences between right and left ureteral measures. Conclusions There is no difference of ureteral length in relation to height or gender (male or female). There is no significant correlation among ureteral length and the considered anthropometric measures.引言 在部分临床场景中，人体结构间的相关性可为腹腔内手术干预的规划提供重要参考。术前预先测定输尿管长度，有助于优化手术术前方案、降低辅助检查成本、合理选择低并发症与少不良反应的双J导管（double-J catheter），并保障治疗依从性。 目的 评估成人尸体的输尿管长度，并分析其与人体测量学指标的相关性。 材料与方法 2009年4月至2012年1月，我们对接受尸体解剖的成人尸体进行输尿管长度测定，并采集以下人体测量指标：身高、肩-腕间距、肘-腕间距、剑突（xiphoid appendix）-脐间距、脐-耻间距、剑突-耻间距及髂棘间间距。随后分析输尿管长度与上述人体测量指标的相关性。 结果 2009年4月至2012年1月期间，我们共对115具成人尸体的115条输尿管进行了解剖。输尿管长度的中位数在不同性别间及不同身高组间均无显著差异。在所有分析亚组及总体人群中，未观察到输尿管长度与所有纳入的人体测量指标存在相关性。左右两侧输尿管长度无显著差异。 结论 输尿管长度与身高或性别（男性、女性）均无显著差异，且与本次研究纳入的所有人体测量指标间均无显著相关性。
