Local excision of ureteral tumours.

A retrospective study was carried out on 20 patients with transitional cell ureteral tumours (TCUT). Surgical exploration of the tumour was performed in 17 patients. Biopsies for frozen section were evaluated for decision concerning the extent of operative intervention. If radical excision of the tumour could be done, and if the ureteral defect could be bridged, a conservative procedure was chosen. Thus, segmental resection of the ureter and primary end-to-end closure of the ureter was performed in 5 patients and ureteroneocystostomy in 3 patients. In nine patients local tumour excision was not feasible and nephroureterectomy was done. The survival rate at 3 and 10 years after ureteral resection as well as after nephroureterectomy was the same, 66% and 16%, respectively. Local excision of non-invasive low-grade ureteral tumours could be safely performed in selected patients, based on local findings and frozen section at the time of surgery.
