Abstract

Abstract:

Objective

To evaluate the efficacy and complications of (Allium) stent implantation in the treatment of benign and malignant ureter obstruction.

Methods

The retrospective study enrolled11 patients (including 5 males and 6 females) with ureter obstruction caused by benign and malignant causes treated in our hospital from October 2018 to May 2019.

Results

Allium stent implantation was performed in11 patients successfully. 1 Allium stent was placed on the affected side with a success rate of 100% in 7 patients. In 4 patients with bilateral obstruction, Allium stent was placed in 3 patients with 1 Allium stent per side and the implantation success rate was 100%; and 2 Allium stent per side in one patient and the implantation success rate was 100%. In one case, CT and anterogram reexamination 15 days after the operation indicated that the hydrocephalus on the affected side was advanced and the obstruction was still present. After the second operation, 1 ureteral Alllium stent was removed from the affected side and new Allium stent was re-implanted. The clinical symptoms of all patients were significantly improved after treatment, and the indexes of serum creatinine, blood urea nitrogen, blood uric acid and renal pelvis separation value were significantly improved compared with that before treatment. None of the patients had stent-related pain or urinary tract symptoms.

Conclusion

The clinical effect of covered reticular stent (Allium) in the treatment of ureter obstruction caused by malignant and non-malignant factors is satisfactory, and it should be selected according to the individual condition.
