Anatomical position and manually cut of the PSS. A Short PSS implanted for a ureteral obstruction, with stent prolongation by a bladder suture. B Long PSS for lumbar-iliac or obstructive upper pelvic ureteral stenosis or stone, with intubation of the obstruction by the stent and then by bladder suture prolongation. a Obstruction by stone in the ureter or at the ureteropelvic junction. b Obstruction due to a stone or a compressive tumor in the ureter. C The characteristic innovation of this stent is that the lower part of the stent was replaced with a 0.3F suture. The thinning out of the lower end appears to limit the catching of the stent on the ureter during breathing movements. Without suture, the short model is 10 cm long and the long model is 20 cm long
