title: Pictorial review of orthotopic neobladder reconstruction: indication, normal postsurgical anatomy, and complications.
abstract: Radical cystectomy with urinary diversion is a common urological procedure performed for the treatment of bladder cancer. Numerous surgical procedures have been developed for urinary diversion. Over the past decade, orthotopic neobladder reconstruction has been used frequently for urinary diversion because of its advantageousness in providing patients with a good quality of life compared with other urinary diversion technique. Knowledge of the indication, surgical procedure, and postsurgical anatomy of orthotopic neobladder reconstruction is essential. While the technique has many advantages, multiple postsurgical complications may occur after reconstruction, including urine leakage, bowel obstruction and fluid collection (lymphocele, urinoma, hematoma, and abscess), neobladder rupture, vesicoureteral reflux, hydronephrosis, urinary tract infection, urinary calculi, abdominal incisional hernia, bowel obstruction, intraneobladder tumor, and tumor recurrence. Radiological imaging including multiple modalities such as intravenous urography, cystography, CT, and MRI plays an important role in the postoperative evaluation of patients with orthotopic neobladder reconstruction and is an accurate method for evaluating complications. In addition, knowledge of appearances on multimodal imaging helps clinicians to select the modality required to achieve an accurate diagnosis of each complication and avoid misdiagnosis.
