Minimal Invasive Treatment in Pelvic-Ureteric Junction Obstruction: A Comprehensive Review

Pelvic-ureteric junction obstruction (PUJO) is a common condition, and one of the lead causes of hydronephrosis in children. Currently, the gold standard treatment of PUJO is open surgery using the Anderson-Hynes-modified dismembered pyeloplasty technique. However, with the advancement of medical technology, several minimal invasive approaches were developed, including endoscopic, laparoscopic, and robotic approach, from which the best choice of surgical technique was yet to be determined. Considering the advantages and disadvantages of these methods, the recommended option is to tailor the best surgical approach to each individual patient, and to the surgeons' preference and experience. Considering these recent advances, a new algorithm is proposed to choose the best minimal invasive modalities invasive treatment to treat PUJO.
