The present invention relates to a ureteral stent (10) having a body (11) and a tail (12). The body (11) of the stent has a renal section (13) intended to be placed in a kidney (R) of a patient, a ureteral section (14) intended to be placed in at least part of a ureter of said patient, and a proximal section (15) arranged at a proximal end of the body of the stent. The tail (12) has at least one thread (16) intended to end in the bladder (V) of said patient. This stent is characterized in that said proximal section (15) has a flexibility greater than the flexibility of the ureteral a section (14) of the stent. The tail (12) is integral with said ureteral section and/or said proximal section (15) and extends beyond the proximal section (15).
