A Rare Case of Bilateral Flank Pain: Anterior Nutcracker Syndrome and Post-pregnancy Hydronephrosis due to Adynamic Ureteral Segment

Since hydroureteronephrosis related to the adynamic ureter segment is mostly seen in childhood, it may be difficult to diagnose in adulthood. The entrapment of the left kidney vein most usually occurs between the abdominal aorta and the superior mesenteric artery (anterior nutcracker syndrome). A case of bilateral flank pain, anterior nutcracker syndrome and hydronephrosis, due to an adynamic ureter segment developing 1 year after giving birth is presented in this paper. According to our research, there is no case report of anterior nutcracker syndrome and hydronephrosis due to an adynamic ureter segment coexistence.
