Breast, prostate, colorectal and bladder cancer as well as non-Hodgkin's lymphoma were the most common other primary malignancies. Men with renal cell carcinoma have an increased risk of subsequent bladder cancer.
Large bowel perforation is an abdominal emergency that results from a wide range of etiologies. Computed tomography is the most reliable modality in detecting the site of large bowel perforation. The diagnosis is made by identifying direct CT findings such as extraluminal gas or contrast and discontinuity along the bowel wall. Indirect CT findings can help support the diagnosis, and include bowel wall thickening, pericolic fat stranding, abnormal bowel wall enhancement, abscess, and a feculent collection adjacent to the bowel. Common etiologies that cause large bowel perforation are colon cancer, foreign body aspiration, stercoral colitis, diverticulitis, ischemia, inflammatory and infectious colitides, and various iatrogenic causes. Recognizing a large bowel perforation on CT can be difficult at times, and there are various entities that may be misinterpreted as a colonic perforation. The purpose of this article is to outline the MDCT technique used for evaluation of suspected colorectal perforation, discuss relevant imaging findings, review common etiologies, and point out potential pitfalls in making the diagnosis of large bowel perforation.
Non-familial bilateral RCC patients represent a distinct subpopulation of renal cancer patients with a good overall prognosis. Partial nephrectomy is an integral part of the surgical management. Although most bilateral tumors present synchronously, asynchronous lesions may occur many years after original nephrectomy, thus committing the patient to long-term follow-up.

Patients with ileal conduits have significantly decreased mental health quality of life whereas patients with continent urinary diversions do not. Therefore, when not medically contraindicated, patients should be offered a continent diversion as the diversion of choice after cystectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
