title: Do Outcomes of Percutaneous Nephrolithotomy in Horseshoe Kidney in Children Differ from Adults? A Single-Center Experience.
abstract: To compare the efficacy, outcome, and safety of percutaneous nephrolithotomy (PCNL) for stones in horseshoe kidney (HSK) in children compared with adults.
  
  
  
  We retrospectively reviewed data of 18 renal units in children (<15 years) and 26 renal units in adult patients with HSKs who underwent PCNL between March 2008 and June 2015.
  
  
  
  Mean age of the study group was 25.92 ± 15.79 with adults having 36.12 ± 11.84 (range 20-65) and children having 10.32 ± 2.88 (range 5-15). Mean stone burden was 311.20 ± 203.99 (104-1080 mm(2)) with children of 211.13 ± 130.21 (104-500 mm(2)) and adults of 382.68 ± 219.27 (114-1080 mm(2)). Success rate is defined as either complete stone free or with asymptomatic and clinical insignificant residuals fragment of <3 mm on postoperative imaging. Initial success rate was 79.54% (86.61% in adults vs 72.22% in children). After auxiliary procedure, the final success rate is 93.18% (adults: 92.30% vs children: 94.44%). Overall complications noted in 12 cases with 23.07% in adults and 33.33% in children, most of them were minor complications.
  
  
  
  There was no significant difference in initial and final success rate. Complication is slightly higher in children although statistically not significant. The outcomes and complications are similar to those reported in other studies of pediatric PCNL.
  
  
  
  Outcomes in child and adult HSKs do not differ significantly with respect to success rate and complications. Children have a relatively smaller stone burden compared with adults with a similar distribution. We found that most of the puncture can be made infracostal in children as well as adults.
