[Robot-assisted laparoscopic pyeloplasty in adults: Excellent long-term results of primary pyeloplasty].
OBJECTIVE
With the development of the robot-assisted surgical technique, robot-assisted pyeloplasty (RAP) has become established as an alternative to open and laparoscopic surgery. Currently there are only a few single-center studies with larger numbers of cases and long-term results. The aim of this study was to investigate perioperative and long-term postoperative success rates of Anderson-Hynes robot-assisted pyeloplasty (RAP) at a single center.


METHODS
We retrospectively reviewed our RAP experience of 61 patients performed by two surgeons between 2004 and 2013 regarding operating time, length of hospital stay, perioperative complication, and success. Overall success was measured in terms of necessary redo pyeloplasty. We also identified patients with temporary stent placement due to symptomatic hydronephrosis or with further obstruction in diuretic renography.


RESULTS
Median age, operating time, and follow-up were 33 years, 195 min, and 64 months, respectively. No conversion to open procedure was necessary. The success rate was 98% (n=60) with 1 patient undergoing open redo pyeloplasty due to a recurrent stenosis. Temporary stent placement was required in 3 patients due to pyelonephritis and dilatation.


CONCLUSIONS
Satisfying long-term success rates including low complication rates of RAP were obtained in this study. RAP presents a safe and standardized procedure for symptomatic ureteropelvic junction obstruction.
