Abstract
PURPOSE
This study aimed to report a multi-institutional retrospective case series of outcomes after robot-assisted laparoscopic pyeloplasty (RALP) in pediatric patients with complex pelvi-ureteric junction obstruction (PUJO).
METHODS
All patients undergoing complex RALP over the last 5 years were included. RALP was defined complex in the following cases of PUJO: anatomic variations including ectopic, malrotated, horseshoe, or duplex kidney and recurrent PUJO after failed open pyeloplasty.
RESULTS
Forty-eight patients underwent complex RALP in four European centers in the study period and included 18 girls and 30 boys with a median age of 8 years (range 5-12). The PUJO was associated with anatomic variations in 35/48 (72.9%), whereas a recurrent PUJO was present in 13/48 (27.1%). A dismembered Anderson-Hynes pyeloplasty was performed in all patients. The median operative time including docking was 178.5 min (range 117-255) and the median anastomotic time was 64.8 min (range 50-76). All patients were discharged on 2nd postoperative day (POD). The median follow-up was 18.2 months (range 14-43). The overall success rate was 95.8% (46/48). Early postoperative complications (< 30th POD) included urinary tract infections (UTIs) and stent-related irritative symptoms in 4/48 (8.3%) [II Clavien], whereas late complications (> 30th POD) included recurrence of PUJO in 2/48 (4.2%), who needed re-operation [IIIb Clavien].
CONCLUSIONS
RALP was safe, feasible, and with good mid-term outcome in complex PUJO. An accurate pre-operative planning, a standardized technique, and an experienced surgical robotic team represented key points to manage successfully such complex cases.
