Ureteral stent insertion failure in obstructive uropathy secondary to cervical cancer

Introduction: To identify preoperative features that predict ureteral stent placement failure in women with obstructive uropathy secondary to cervical cancer. Methods: Observational, descriptive, analytical study. Clinical registries of patients diagnosis cancer were reviewed. Fifty-two attended between January 2017 2021 included. Diagnosis consisted hydronephrosis or hydroureter imaging studies and elevation baseline serum creatinine blood urea nitrogen uremic syndrome. An analysis variables interest was carried out assess the association failure. Results: We observed overall rate failed 55.8%. did not find any differences characteristics successful unsuccessful placement. A higher percentage urinary diversion on admission had a decrease output (58.6% vs. 30.4%, p=0.04), syndrome (51.7% 21.7%, p=0.02), as well an increased median (6.6 2.6 mg/dL, p=0.03) compared cut-off value 3.4 mg/dL yielded sensitivity 69% specificity 65.2% for (AUC=0.674, 95% CI 0-52-0.82; p=0.03). Conclusion: Our data suggest distal obstruction evidenced by imaging, regardless extent invasion, is most important factor related
