Combined use of retroperitoneal laparoscopy and bladder resectoscope to treat renal and ureteral tumor occurring at the same side of transplanted kidney (report of 5 cases) / 中华器官移植杂志

ABSTRACT

Objective To evaluate the operative characteristics and efficacy of retroperitoneoscopic resection of renal, ureter and partial bladder for the treatment of native renal pelvic and ureteral transitional cell cancer occurring at the same side of transplanted kidney.Methods In 5 cases of renal transplantation, there were 2 cases of right native renal pelvic cancer, 1 case of right native renal (pelvic) and ureter cancer and 2 cases of right ureter cancer respectively. The transplanted kidney was in the same iliac fossa side of the tumor. All 5 patients were subjected to nephroureterectomy and bladder cuff excision by retroperitoneoscopic technique.Result Five operations were completed successfully. The operative time was 180 to 280 min, and the blood loss was 50 to 200 ml. The recovery of intestinal function after operation was 12 to 36 h. The urine output was 1 500 to 4 000 per day. Postoperative serum creatinine was still normal. The mean hospital stay after operation was 4.5 days.Conclusion Retroperitoneal laparoscopic nephroureterectomy and bladder cuff excision is a good method to treat the native renal pelvic and ureteral transitional cell cancer occurring at the same side of transplanted kidney. The procedure is safe and less invasive, which provides a good protection of transplanted (kidney).
