• Fig GU 1-1 Solitary kidney. (A) Excretory urogram demonstrates a normal left kidney with no evidence of right renal tissue. (B) Aortogram shows two renal arteries to the left kidney (arrows) and no evidence of a right renal artery, thus confirming the diagnosis of unilateral renal agenesis.

• Fig GU 1-2 Pelvic kidney. The arrows point to the collecting system.

• Fig GU 1-3 Intrathoracic kidney (arrow).

Fig GU 1-4 Malrotation of the left kidney. Note the apparent lateral displacement of the upper ureter and the elongation of the pelvis.

• Fig GU 1-5 Horseshoe kidney (arrows). The prolonged nephrogram and delayed calyceal filling on the left are caused by an obstructing stone at the ureteropelvic junction on that side.

Fig GU 1-6 Splenomegaly. Downward displacement of the left kidney. The arrow points to the inferior margin of the spleen.

• Fig GU 1-7 Calcified adrenal teratoma (arrow). Downward displacement of the left kidney.

Fig GU 1-8 Renal cell carcinoma. Upward displacement of the right kidney and distortion of the collecting system by the large lower pole mass.

Fig GU 1-9 Wilms' tumor. Massive displacement of the left kidney across the midline by a huge mass filling much of the left side of the abdomen.

• Fig GU 1-10 Kidney transplant.
