Role of T2wi as a primary method in detection of late post radical cystectomy complications

PurposeTo evaluate the role of T2wi as a primary method in detection of late post radical cystectomy complications.Patients & methods236 patients underwent radical cystectomy and urine diversion. Postoperatively, every 6 months MRI was done: T2wi of the abdomen and HR-T2wi of the pelvis at 1.5T searching for postoperative complications.Results12/236 cases (5%) with post-operative complications in the form of fluid collection, 40/236 cases (16.9%) with local recurrence; 3 cases were diagnosed by histology as inflammatory condition, 19/236 cases (8%) with lymph node enlargement, 39/236 cases (16.5%) with hydronephrosis, 10/236 cases (4.2%) with unilateral and 29/236 cases (12.3%) with bilateral, 37/236 cases (15.7%) with pyelonephritis, 9/236 cases (3.8%) with bone metastasis, 3/236 cases (1.3%) with liver metastasis, pouch stone in 5/236 cases (2%), 4/236 cases (1.7%) with pelvi-calyceal masses and 83/236 cases (35.2%) with no abnormality detected. The accuracy of the MRI in detection of the complication was 98.7%.ConclusionAxial T2wi of the abdomen and pelvis is an accurate primary method for evaluation of radical cystectomy as it is a simple technique with no intravenous contrast media or radiation exposure.
