[Laparoscopic segmental ureteral resection with ileal-ureter substitution for ureteral urothelial carcinoma]

Ureteral resection for the mid-ureter urothelial carcinoma is the operation of choice in patients with low-grade tumors. However, extensive excision within normal tissues may lead to difficulty in appropriate apposition of the ends of the ureter, while incomplete resection increases the risk of oncological progression. This article describes the first experience with laparoscopic segmental ureteral resection with the ileal - ureter substitution for mid-ureter urothelial carcinoma. In this case, a short non-reconfigurated segment of the ileum was interposed between the distal and proximal ends of the resected ureter. Operative time was 230 min, and blood loss was less than 100 ml. No complications were observed. The patients postoperative hospital stay was seven days. Follow-up examination 12 months after surgery showed no evidence of the disease progression and preserved normal renal function. The proposed method may be considered as an alternative treatment for carefully selected patients.
