[Robot-assisted operations in pelvic region]

Nine patients were operated on with the use of robotic complex. In 3 cases the nonorganic retroperitoneal pelvic tumor was removed, the 4 full-layer urinary bladder and ureteral orifice resections and simultaneous ureteral plasty together with ileal-obturatory lymphadenectomy (2 - cancer of the urinary bladder cervix, 1 - pheochromocytoma of the urinary bladder) and 2 ureterocele with complete ureter duplication and megaureter were performed. Technical aspects of the robotic layerwise resection of the neck of the urinary bladder were worked out. The operation time varied from 1 hour 45 minutes to 4 hours 45 minutes. The maximal blood loss was 100 ml. One patient developed the acute respiratory failure. The were no other postoperative complications. The postoperative hospital stay was 7-12 days.
