Uretero-pelvic junction obstruction in children: Is vascular hitch an effective and safe solutions in very long term outcome? Report of 25 years follow-up.

Vascular (VH) according to Hellstrom-Chapman technique is considered a safe and effective alternative approach to pure extrinsic Ureteropelvic Junction Obstruction (UPJO) with good results in short and medium term, but few data are available on long and verylong term outcomes. Our aim is to evaluate VH long and very-long term outcomes in patients treated in pediatric age focusing on relapse, development of hypertension and/or inferior polar kidney hypotrophy during puberty and adulthood. From 1990 to 2015 in our Department 76 children were treated by open or laparoscopic VH for pure extrinsic-UPJO.
