Objective: To study the people living donor renal pelvis , calyceal clinical anatomical classification for the clinical treatment of renal pelvis, calyces disease , especially in minimally invasive surgery, providing morphological evidence . METHODS : This study selected adult volunteers 50 (100 kidneys ) , including 26 male and 24 female , intravenous pyelography display pelvis, calyces , pelvis shows by 16-slice CT reconstruction method calyceal three-dimensional morphology diagram , controllable rotation , multi-angle observation and morphological study of the pelvis , calyceal spatial structure . Results : ( 1) renal lights an average of 11.2 , asexual , no significant difference between the left and right side ; renal lights can be divided into the neck and no neck type , both appeared ratio of 7.38:1 , both the number of Poor distribution asexual . This paper argues that , regardless of whether the neck , all contact with the renal papilla pouch surface should be that the renal lights , found in the survey accounted for 11.93% of the total number of renal lights no neck renal light . ( 101 2) 100 kidneys found pelvis , 74 pelvis on the next two kidney lights , 17 pelvis upper, middle , three kidney lights , 10 kidney large lamp pelvis renal The light directly opening in the pelvis , the the three proportion to 1.7:7.4:1 . Kidney lights a rate of 17 % . ( 3) The pelvis is divided into three types: mature the ampulla type ( significant renal big lights , big lights merged into ampulla -like pelvis ) , embryonic ampullary type ( kidney large lamp , renal light opening directly in cystic renal pelvis ), branching type ( renal pelvis , kidney light Consistency at no enlargement of the renal pelvis to form directly transitional ureter ) 100 kidneys (1 side kidney double pelvis , a total of 101 renal pelvis ) , mature the ampulla pelvis 44 10 months , embryonic ampullary pelvis , branching pelvis 47 three for 4.4:1:4.7 . Conclusions: The number of renal lights sex, left and right side differences ; neck renal small light appeared significantly higher than the no - neck type renal lights , both the number of distribution asexual . Up and down two kidney lights is the most common , renal big light in the next three kidney large lamp , followed by renal light rare . The pelvis typing branching pelvis up to see , the mature ampullary pelvis followed by embryonic the ampulla -type renal pelvis is the most rare .
