(a) A posterior view of the affected (left) kidney showing three major calyces (asterisks) joining outside of the kidney and a dilated renal pelvis (plus sign). (b) A view inside the affected (left) kidney showing normal-sized minor calyces and pyramids without evidence of hydronephrosis. (c) Also notable was a slight, yet still noticeable, stenosis of the ureteropelvic junction: (i) pre-ureteropelvic junction (diameter: 0.88 cm), (ii) ureteropelvic junction (diameter: 0.50 cm), (iii) post-ureteropelvic junction (diameter 0.75 cm).
