Abstract: Objective: To evaluate the application value of T-tube fistula in ureteral stenting insertion in patients with advanced cervical cancer under the condition of unclear ureter openings through cystoscopy. Methods: The ureter openings of 18 sides in 12 patients with advanced cervical cancer complicated with hydronephrosis could not be found by cystoscopy. The ureter openings were explored by T-tube fistula under the straight incision of back,perfusing methylene blue,wire search under X-ray and anterograde venography,ureteral stent was retrogradely implanted into ureter. Results: The ureteral stents were successfully implanted in 17 sides. T tube in 1 case with lower ureter atresia was placed for external drainage,which was replaced after 1 month. Conclusions: The effects of internal drainage in the patients with advanced cervical cancer complicated with unclear ureter openings through cystoscopy maybe good,external drainage is not preferred. T-tube fistula under the straight incision of back is less trauma and high success rate. Increasing the success rate of internal drainage can improve the life quality of the patient,which is worthy to spread.
