Findings: Figure 1 (KUB on day 1 and day 3):
1. Relative increased opacity in left lower abdomen with decreased
   bowel gas,  nature to be determined.

Figure 2,3 (Ultrasound on day 3):
1. Severe left hydronephrosis with a dangling material.
2. Fluid accumulation in left lower abdomen with septations,
   nature to be determined.

Figure 4-11 (MRI on day 3):
1. Marked dilatation of left calyces and renal pelvis with
   rapid tapering at ureteropelvic junction, in favor of
   congenital ureteropelvic junction obstruction.
2. A 1.5cm round soft tissue with stalk fixed to the margin of
   a defect (1.6cm) in anterior wall of left dilated renal pelvis,
   suggesting kidney rupture with a parenchymal fragment
   mixed with hemorrhage.
3. Moderate fluid accumulation in left retroperitoneum with
   some septation, due to urinoma with dissected retroperitoneal
   fascias.

Figure 12-14 (percutaneous nephrostomy drainage, PCND, on day 3):
1. Bloody urine from left renal pelvis.

Figure 15 (KUB, post PCND):
1. Left PCND in place.

Figure 16 (antegrade pyelonephrography, AP, on day 6):
1. Severe stenosis of left ureteropelvic juction, in favor of
   congenital ureteropelvic junction obstruction.
2. No contrast media extravasation, suggesting healed renal pelvis.
Diagnosis: Left renal pelvic rupture associated with congenital ureteropelvic junction obstruction and severe hydronephrosis.
