Laparoscopic transposition of lower-pole crossing vessels: Long-term follow-up of 33 patients at puberty

In the long-term follow-up, most adolescents successfully treated during childhood by laparoscopic transposition of LCPV for PUJ extrinsic obstruction remain asymptomatic, with normal arterial blood pressure, and normal renal ultrasound when they reach puberty.Table 1.
