Henning OLSEN Aarhus University Hospital, Skejby, Department of Urology, Aarhus N, DENMARK PURPOSE When surgical reconstruction for UPJO is indicated, access can be gained either by the transperi- toneal or the retroperitoneal approach. No study has shown significant differences in complication rates between transperitoneal (TA) and retroperitoneal (RA) pyeloplasty and the choice of route depends on the surgeon's preferences. We assessed the complication rates in children (RA) and adults (TA) to contribute to the discussion about which route to take. MATERIAL AND METHODS Data were obtained from UroLap, a Danish nationwide quality assessment database. Data were analysed from 2009 and to 2014 after introduction of the Clavien-Dindo classification. Operative data were sampled prospectively, while incidence of complications was obtained by chart review retrospectively. In this period a total of 93 children (3–16 years) were admitted for robotic RA pyelo- plasty and 113 adults (>16 years) for robotic TA pyeloplasty. RESULTS Conversion rates to open surgery were 3,5 % in adults and 4,3 % in children. A total of 89 RA pyeloplasties in children and 109 TA pyeloplasties in adults were completed as robotic-assisted laparoscopic procedures. Mean operative time was 137 minutes in children and 103 minutes in adults. Length of hospitalization was 1.9 days in children and 1.6 days in adults. Overall complica- tion rate (Clavien-Dindo) was 16,9 % in children and 24,8 % in adults. Grade 1 occured in 8,9 % in children and in 8,6 % of adults. Grade 2 occurred in 3,4 % of children and in 10,1 % of adults. Grade 3 was reported in 4,5 % of children and 6,4 % of adults. Urinary leakage was seen in five adult patients. No grade 4 or 5 complications were reported. CONCLUSIONS This series of robotic retroperitoneal pyeoloplasty in children is the largest to our knowledge and contribute to a more valid estimate of the true complication rate of robotic-assited retroperitoneal pyeloplasty in the paediatric population. No clinically significant urinary leakage occurred in children, which strengthens the hypothesis of a closer anastomosis sealing after disinflation of the retroperi- toneal space.
