Failed pyeloplasty in children: Is robot-assisted laparoscopic reoperative repair feasible?
Abstract
In this study we aim to demonstrate that robot-assisted laparoscopic (RAL) reoperative repair is safe and effective and even less technically demanding than open repair for recurrent ureteropelvic-junction obstruction (UPJO). A retrospective study was conducted of all cases of failed open pyeloplasties who underwent RAL reoperative repair at our institution between January 2010 and December 2013. The general surgical procedure was the same we previously described for robot-assisted laparoscopic pyeloplasty. Success was defined as: improvement in the degree of hydronephrosis at ultrasound, improvement of diuretic washout time at postoperative diuretic renogram (<15 min), improvement or at least stable differential renal function and absence of symptoms. These radiographic and symptomatic criteria of success were considered the primary outcomes. Secondary outcomes included complications and length of hospital stay. Between 2000 and 2013 a total of 153 patients underwent open Anderson-Hynes dismembered pyeloplasty. Of these 9 (6%) had recurrent UPJO. Four patients underwent open redo pyeloplasty. As a result, our study population comprised 5 children who underwent reoperative RALP repair. Patient characteristics and outcomes are s...Continue Reading
