We report 2 cases of ureteral stump calculi presenting years after nephrectomy. Stones in the ureteral stump are extremely uncommon, and their occurrence has led us to review the possible mechanisms underlying their etiology.
A case of sigmoid carcinoma in a 16-year-old boy is presented and the topic of colonic carcinoma in the young is reviewed. Although colon carcinoma in the younger patient is uncommon, its prognosis is distinctly worse than in the adult population, because the preponderance of mucinous adenocarcinoma in children and young adults represents a more virulent type of colonic malignancy and because the delay in diagnosis contributes to a more advanced stage of the disease at the time of presentation. When dealing with symptoms potentially referrable to this disease, a thorough diagnostic work-up should ensue.
