Obstructive uropathy and acute-on-chronic kidney disease from common iliac artery aneurysm: A case report

Table 1 Selected published cases of iliac artery aneurysm causing ureteral obstruction

Ref.	Age/sex	Aneurysm location	Imaging	Presentation	Management	Outcome
Sangey and Moledina[7]	NR	Internal iliac artery	CT + conventional angiography	Hydroureteronephrosis	Open surgical repair	Renal function improvement
Sato et al[8]	NR	Common iliac artery	CT angiography	Spontaneous ureteral rupture	Ureteral stent + EVAR	Full recovery
Jalil et al[4]	NR	Iliac artery (thrombosed)	CT	Chronic obstruction, CKD	Serial ureteral stenting	Stable long-term renal function
Present case	63/female	Right common iliac artery	Noncontrast CT (contrast contraindicated due to AKI)	Acute-on-CKD, severe hydronephrosis + hydroureter; no pulsatile mass on exam	PCN; EVAR at 8 weeks post-discharge	Partial renal recovery (Cr 1.9 mg/dL → 1.8 mg/dL at 3 months); nephrostomy removed at 12 weeks

NR: Not reported; CT: Computed tomography; EVAR; Endovascular aneurysm repair; CKD: Chronic kidney disease; AKI: Acute kidney injury; PCN: Percutaneous nephrostomy; Cr: Serum creatinine.
