title: Case 230: Congenital Inguinal Herniation of the Left Ureter (Extraperitoneal Form).
abstract: History A 52-year-old man with a history of urinary tract infections and a previous clinical diagnosis of left inguinal hernia presented to the nephrologist with recent onset of dysuria and increasing swelling in the left inguinoscrotal region in the absence of fever or scrotal trauma. There was no relevant surgical or family history. The general physical examination findings were unremarkable, with a normal abdomen at both visual inspection and palpation; urogenital examination revealed a small left-sided palpable mass of the testis, compatible with an inguinal hernia or hydrocele. At first, gray-scale and color Doppler ultrasonographic (US) images of the testes and the inguinoscrotal region were obtained. Contrast material-enhanced computed tomographic (CT) images of the lower abdomen and pelvis were then obtained to further evaluate the urinary tract.
