To explore therapeutic value of radiotherapy combined retrograde ureteral catheterization on Cervical cancer complicated with ureteral obstruction. Methods 63 cases of cervical cancer patients complicated with ureteral obstruction were retrospectively analyzed With ureteral stent guided by cystoscope，retrograde double J stent was performed before Concurrent chemoradiotherapy. Ureteral stents success rate and renal function were compared before and after cannulation. The effect of ureteral stent placement on radiotherapy in Cervical cancer complicated with ureteral obstruction was observed. Results 50 of 63 patients were Successful in retrograde ureteral catheterization. Renal function significantly improved compared with the pre-operation. The overall response rate was 94％ (47／50)，including CR，35 cases；PR，l 2 cases；NC，3 cases．Double J tube had no significant effect on radiation therapy. Conclusions Radiotherapy combined retrograde ureteral catheterization is an effective method to treat cervical cancer complicated with ureteral obstruction. The technique is easy and safe without complications．
