title: Functional Results of Laparoscopic Pyeloplasty in Children: Single Institute Experience in Long Term.
abstract: OBJECTIVE
  The aim of this study was to evaluate the long-term functional outcomes of laparoscopic pyeloplasty (LP) in children for consecutive cases of single institute.
  
  
  METHODS
  Our laparoscopy database was investigated for children in terms of LP between June 2008 and April 2015. All the patients had ureteropelvic junction obstruction (UPJO) and LP was performed. Demographic data including age, gender, side of UPJO, operation time, estimated blood loss (EBL), hospital stay and complications according to Clavien classifications were recorded. Renal ultrasonography and diethylenetriamine penta-acetate (DTPA) scintigraphies were respectively performed 3, 12 and 24 months after surgery. Statistical analyses were performed and p value was accepted as significant at <0.05.
  
  
  RESULTS
  Mean follow-up was 34 ± 4.7 months. The mean age was 13 (6-72) months. A total of 153 (110 boys and 43 girls) LP patients enrolled. Of that, 93 (60.78%) LP were in left side and 60 (39.21%) were in right side. Three cases needed open conversation according to difficulties in anastomosis. Aberrant crossing vessel was observed in 12 (7.84%) patients. The mean operation time was 155 ± 21 min and the mean EBL was 22 ± 11.1 ml. The mean hospital stay was 3.4 days. Anastomotic leakage was the common complication (in 13 patients) that was successfully managed conservatively (Clavien 1). Eight patients experienced unsuccessful LP and underwent open pyeloplasty (Clavien 3b). The mean split renal function significantly increased in DTPA scintigraphy in follow-up. The overall success was 91%.
  
  
  CONCLUSIONS
  The LP procedure can be an effective and safe surgical method for childhood UPJO, specifically in the experienced hands of pioneer centers.
