Ureteral obstruction in advanced cervical cancer can be relieved with effective and relatively safe method such as ureteral stenting and percutaneous nephrostomy. Between Jan, 1986 and Dec. 1992, forty cervical cancer patients who underwent urinary diversion with percutaneous nephrostomy(PCN) and ureteral stents at Yonsei University, Medical College(YUMC) has been retrospectively analysed. These patients were allocated into 3 groups: group I - ureteral obstruction on initial presentation(n=19), group II - ureteral obstruction in recurrent or persistent cancer(n=16), group III - ureteral obstruction developed after or during primary treatment without any evidence of recurrence(n=5).
