Patient Data

Age: 50 years
Gender: Female

Markedly distended urinary bladder reaches the level of L2 vertebrae with bilateral hydronephrosis and hydroureters. Markedly dilated small bowel loops, ileocecal junction, the right side of the colon and transverse colon where the large colon is markedly distended till a transitional zone is demonstrated at the level of the rectosigmoid junction being compressed by the markedly distended bladder against the patient's vertebral column. Abnormal reflux of the cecal content into the terminal ileum suggests colo-ileal reflux. No portal venous gas.
