Study progress in treatment of congenital ureteropelvic junction obstruction

Abstract

Congenital ureteropelvic junction obstruction (UPJO) is a common urinary tract obstructive disease and it is one of the common causes of hydronephrosis in children and adolescents.Untreated UPJO may cause aggravation of hydronephrosis, chronic infection, urinary calculi, or even worsening of renal function.UPJO′s treatment includes conservative and surgical treatment, and surgical treatment not only includes endoscopic surgery and classic open pyeloplasty, it also includes minimally invasive techniques such as laparoscopy and robot-assisted laparoscopic surgery.In recent years, the application of minimally invasive techniques in pyeloplasty has been greatly improved and developed, now the research progress of UPJO in treatment is reviewed. Key words: Ureteropelvic junction obstruction; Hydronephrosis; Recurrent pyeloplasty; Minimally invasive treatment
