We hypothesized this approach is safe and feasible for a variety of pediatric urologic reconstructive procedures. MATERIAL AND METHODS We retrospectively reviewed all major robotic procedures entered into an IRB approved data registry. The analysis was performed only for procedures in which 5 mm instruments were used exclusively with hook diathermy. Procedures that utilized 8 mm instrumentation were excluded from the study. Data were abstracted according to patient age, weight and robotic surgery performed. Outcomes included post-operative complications, operative time, operative blood loss, need for assistant port placement and conversion rates to open or laparoscopic surgery. RESULTS From 2012 to 2016, 220 consecutive pediatric RAL urological surgical cases were performed on 201 patients. These comprised pyeloplasty (n=102) 46.4 %, ureteral reimplants (n=84) 38.2 % and ipsitateral ureteroureterostomy (n=34) 15.5 %. Median age at surgery was 4 years (3 months to 18 years). There were no conversions to open or laparoscopic surgery. Placement of an ad- ditional Assist port was documented in 7 cases. Severe (Clavien grade 4) complications occurred in 2 patients requiring ICU admission: one for sepsis and one ventilator dependent patient having increased work of breathing post op. Intra-op blood loss was minimal (<50 ml) in 97 % of cases. Patients ≤ 1 year of age comprised 28.6 % of the study population. Univariate analysis revealed no association between age and occurrence of complications (p=0.957) CONCLUSIONS This study represents one of the largest series of consecutive robotic assisted laparoscopic surgery using 5 mm instruments in pediatric urology. We conclude that the use of 5 mm instruments gives excellent operative outcomes in pediatric reconstructive procedures.
