Abstract

Objective

The aim of this study was to present a paradigmatic case where the new-generation Allium URS stent was the optimal choice to treat a malignant ureteral stenosis.

Methods

We describe in detail all the steps of our surgery, performed on a 69-year-old patient with left hydronephrosis caused by lumbo-aortic nodal metastases compressing the ureter. The patient was intolerant to double-J stent due to strong irritative urinary symptoms. Allium URS stent was positioned under fluoroscopy in replacement of pre-existing double-J stent.

Results

Our approach was successful and irritative urinary symptoms disappeared. At 6 months, the Allium URS was correctly positioned and no hydronephrosis was detected on ultrasound. The stent can be left in place for a maximum of 3 years.

Conclusions

In complicated scenarios of chronic ureteral stenosis, the new-generation Allium URS can be an interesting option to treat the obstruction while sparing the patient the irritative urinary symptoms and periodic replacements typical of a double-J stent.
