(I Normal Urography Findings 1、 Kidney: (1) parenchyma: Homogeneous density bilateral identical (2) Renal calyces: minor calyces(usually 6-14) and major calyces (usually 2-4) 1) Minor renal calyces: egg-cup shaped Major renal calyces: long tubular shaped neat edge 3)Renal pelvis: horn shaped, within the confines of kidney but may also be extrarenal
1、Kidney： （1） parenchyma: Homogeneous density, bilateral identical. （2）Renal calyces: minor calyces (usually 6-14) and major calyces (usually 2-4). 1）Minor renal calyces: egg-cup shaped. 2）Major renal calyces: long tubular shaped, neat edge. 3）Renal pelvis: horn shaped, within the confines of kidney, but may also be extrarenal. （Ⅱ） Normal Urography Findings
(I Normal Urography Findings 2 Ureters: Total length of about 25 30cm, width 3 7mm (1) Segments: Abdominal segment is connected with renal pelvis, down the line along the spine. After across the pelvis over the inside edge of sacroiliac joints, it is called basin segment. Curved into bladder, it is called wall segment. (2) Three physiological narrowing: Junction with renal pelvis; over the pelvis; bladder entrance 3 Bladder: Size and shape depends on degree of filling
2、Ureters: Total length of about 25 ~ 30cm, width 3 ~ 7mm. （1）Segments: Abdominal segment is connected with renal pelvis, down the line along the spine. After across the pelvis over the inside edge of sacroiliac joints, it is called basin segment. Curved into bladder, it is called wall segment. （2） Three physiological narrowing: Junction with renal pelvis; over the pelvis; bladder entrance. 3、Bladder: Size and shape depends on degree of filling. （Ⅱ） Normal Urography Findings
