Abstract:
We report a rare case of left nutcracker syndrome and right ureteropelvic junction obstruction in a young woman who suffered flank pain and hematuria. The diagnosis was confirmed with the help of Doppler ultrasonography, retrograde pyelography, magnetic resonance angiography, and magnetic resonance urography. A surgery that involves left renal vein decompression and dismembered Anderson-Hynes pelvioplasty was performed. The patient was followed up for 23 months, and her symptoms were relieved.
