Ureteropelvic junction stenosis

It is a congenital malformation which concerns the reins and it causes the affected rein to have trouble expelling urine. Along with itself, it brings:
1) Hidronefrosis
2) Urinary infection (pyelonephritis).

Surgery therapy:
1 Open surgery of the junction
2 Use of laser (Thulium and Holmium) which lets us operate endoscopically at junction level, incising it and placing a stent (double J which will be removed after a month) that is to keep the passability of ureter, fostering its healing.
