Urinary tract obstruction: obstruction is visualized in the proximal ureter just at the exit of the kidney, calyces and renal pelvis dilated, 10 min kidney filling, ut obstruction at the arrow, hydronephrosis, renal parenchymal destruction, untreated ->renal failure. Ivu: right kidney behind in process, still at nephrogram stage left kidney in pyelogram stage but dilated and abnormal, picture taken around 10 min mark. Renal agenesis: unilateral failure of right kidney to develop at all. Renal agenesis: hypertrophy of single kidney, dilated left kidney, right kidney not developed. Hypoplasia: one or more kidneys develop incompletely. Complete: two separate pelves, each with ureter and ureteral opening. Horseshoe kidney: kidneys are connected or fused across midline usually at lower poles by an isthmus.
