Retroperitoneoscopic proximal ureter resection and ureteroureterostomy as an alternative management for upper tract urothelial carcinoma: A case report.

Radical nephroureterectomy (RNU) with bladder cuff removal is the treatment of choice for upper tract urothelial carcinoma (UTUC). Partial ureterectomy (PU) with ureteroureterostomy in this case has shown a good result. We herein report an elderly woman with adenocarcinoma colon complaining gross intermittent hematuria and solid ureteral mass on NCCT. Patient declined RNU, so we performed PU with ureteroureterostomy. Histology examination showed high-grade infiltrating urothelial carcinoma with negative margin. Four cycles of Gemcitabine and cisplatin were given. Routine follow up and evaluation were done without any mass progression. PU and ureteroureterostomy with adjuvant chemotherapy are an alternative procedure for UTUC.
