Abstract
Objective
This study aimed to evaluate the efficacy of ureteral stent placement for the treatment
of hydronephrosis secondary to cervical cancer and analyze factors that may predict
failure of ureteral stent placement and the differences between ureteral stent placement
and percutaneous nephrostomy.
Study design
Clinical data of patients with cervical cancer complicated with hydronephrosis admitted
to our hospital from July 2008 to August 2018 were retrospectively analyzed. To evaluate
the efficacy of ureteral stent placement and percutaneous nephrostomy in the management
of hydronephrosis secondary to cervical cancer.
Results
A total of 89 patients were analyzed. A ureteral stent was successfully placed in
60 patients. Indwelling stent failed in 29 patients, and then percutaneous nephrostomy
was performed. Both surgical procedures were safe and effective. There was a significant
correlation between the success rate of ureteral stent placement and the degree of
hydronephrosis and the length of the ureteral obstruction. There was no significant
difference in the incidence of complications following ureteral stent placement and
percutaneous nephrostomy, while there were significant differences between the two
treatment modalities in terms of surgical time, hospitalization time, and surgical
cost.
Conclusion
Ureteral stent placement is the preferred method for the treatment of hydronephrosis
secondary to cervical cancer. However, in patients with more severe hydronephrosis
and ureteral obstruction >3 cm in length, percutaneous nephrostomy may be more appropriate.
