Imaging of the various continent urinary diversions after cystectomy

초록

Continent urinary diversions have recently become the preferred procedures rather than performing an ileal conduit. Intravenous urography, pouchography, and computed tomography scans are frequently used for postoperative evaluation of patients with bladder carcinoma. During postoperative follow-up imaging studies, the radiologist must keep these 4 facets in mind as his primary focus: 1) the detection of newly developed urotbelial tumors, 2) the detection of metastasis, 3) the detection of postoperative complications, and 4) the monitoring of upper urinary tract distention. Various surgical techniques that are used in continent diversions alter the normal anatomy and make the imaging interpretation difficult. An accurate interpretation can be made only if radiologists become familiar with the various surgical procedures and the appearances of various postoperative anatomic changes.
