title: [Hydropneumatic dilatation of the ureter: A technical option in ureteropyeloplasty].
abstract: BACKGROUND
  The pyeloureteric junction (UP) is the site of obstruction commonest in the upper tract urinary. Several surgical techniques exist and the main complication is the stricture by the disproportion between both ends. The hydropneumatic dilatation of the ureteric would increase of the 5:1 to 2:1 the light of the ureter, improving technically anastomosis and reducing complications.
  
  
  METHODS
  They studied 27 patients with diagnose of Estenosis UP in the Paediatric Urologist Service of CMN 20 of November of the ISSSTE, being made dismembered Pyeloplasty pyeloureteric in all, introducing Fogarty catheter in the Ureter carrying out the hydropneumatic dilatation of the same one, introduction of catheter double J in ureter and in the last patient without this, previous one to the anastomosis. All had a pursuit of 6 months.
  
  
  RESULTS
  Of the 27 patients, 21 masculine ones (77.78%), 6 feminine ones (22.22%), of the right side 10 (37.04%), left 14 (51.85%) and bilateral 3 (11.11%). In the 27 studied patients postoperating complications did not appear. To all the patients I am made the dilatation to them hydropneumatics of the Ureter during UP plasty, did not present/display postoperating complications, the anastomosis is carried out with greater technical facility since the light of the Ureteric increase from 5:1 in 2:1, and in I complete case without ferulization of the Ureter, I do not present/display complications. DOSCUSSION: The hydropneumatics dilatation of the Ureter is a technical option in the Surgical handling of stricture UP, facilitating the anastomosis, diminishing the postoperating complications, making the ferulization do withoutible of the Ureter.
