Abstract: Objective: To investigate the proper treatment of upper urinary tract obstruction due to cervical cancer. Methods: 35 cases with upper urinary tract obstruction due to cervical cancer treated 2002.5-2003.9 were included: 17 advanced cancer without previous treatment; 5 without the evidence of tumor but treated with chemotherapy or radiotherapy previously; 13 recurrent tumor, 27 patients had hydronephrosis bilaterally. Endoscopic internal stent drainage was tried for 5 initial cases and 18 previously treated patients, 4 and 6 were successful respectively. Among the other 12 previously treated patients, 3 received bilateral ureterostomsis, 4 received unilateral transcutaneous nephrostomy and the rest received no further treatment. Otherwise, the other 13 with primary locally advanced cancer received operative retroperitoneal ureteral catheterization. Results: All the 5 patients without further treatment died within 2 months, while the nephrohydrosis of the 23 cases with catheterization improved, among them, 4 died of cancer progression, 10 had changed the stents successfully, 2 failed to change the stents, the others were just in follow-up and it was not the timing to change stents.3 of the 23 cases treated with endoscopy developed infection. Among the 7 received external drainage (follow-up, 1-9 months), 4 nephrostomic tubes were jamed and 1 tube dislodged, no treatments associated death occurred. Conclusions: Endoscopic internal stent drainage was the choice treatment for the patients with upper urinary tract obstruction due to cervical cancer,if failed,should treat properly according to the different cause of obstruction and patients different condition.
