Laparoscopic Pyeloplasty for Ureteropelvic Junction Obstruction

For ureteropelvic junction obstruction (UPJO), the standard of surgical care is dismembered pyeloplasty. This applies both for intrinsic but also for extrinsic etiology of the UPJO. When in 1995, Peters described for the first time laparoscopic pyeloplasty in children, the era of laparoscopic pediatric urological surgery began. Nowadays, laparoscopic dismembered pyeloplasty in children has evolved to become the gold standard. In this article, we report a standardized technique of laparoscopic transperitoneal dismembered pyeloplasty for infants and children. The described single steps of the procedure are reproducible regardless of age and weight and thus offer a high surgical success rate.
