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.

Abstract

Fibroepithelial polyps are extremely rare benign tumors arising from mesodermal tissue in the ureteral wall in children, that can cause ureteropelvic junction obstruction. In this report, we present an 11‐year‐old boy complaining of left intermitent lumbar pain related with ipsilateral hydronephrosis. Surgical exploration revealed several endoluminal polyps located at the ureteropelvic junction, obstructing the lumen of the ureter. Standard treatment consists in resection of the affected ureteral segment followed by open or laparoscopic dismembered pyeloplasty. The prognosis is excellent.
