Pelviureteric junction obstruction (PUJO) is the condition where flow of urine from the renal pelvis to the ureter is hindered due to various intrinsic or extrinsic causes. Lower pole renal vessels are mostly associated with this condition. Unlike our case, there have been reports of ureter being kinked around the Veins of Retzius but there has been no case report of ureter being kinked around the superior mesenteric vein directly causing features of PUJO.
