title: Essential role of using virtual pyeloscopy in the diagnosis of small satellite renal pelvic tumour in solitary kidney patient.
abstract: Virtual pyeloscopy (VP) plays an important role in the organ-sparing nephroscopic tumour resection and traditional pole resection, especially when a fibreoptic ureteroscopic examination cannot be performed. A 67-year-old man developed macroscopic hematuria. Abdominal computed tomography (CT) and cystoscopy revealed a lower calix renal stone and a 20-mm lower pyelon mass suggesting transitional cell cancer. An additional small satellite lesion in the pelvico-ureteral junction was supposedly present. Three-phase MultiDetector CT with VP showed a solitary 3 to 4-mm renal pelvic lesion beyond the known calix stone and lower pole mass. In our case, VP played an important role in the organ-sparing nephroscopic tumour resection and traditional pole resection.
