..We have previously reported a high rate of urinary metabolic abnormalities in stone forming children. We compared urinary chemistry values in normal and stone forming children...

..We previously reported urinary metabolic evaluations in stone-forming children using adult references. We now assess normal SS values in children...

..However, complications such as catheter false passage with subsequent intraperitoneal instillation of irrigation can lead to significant morbidity. We present our experience with the diagnosis and management of this condition...

..The purpose of this study was to determine which children are at the greatest risk for recurrent stone formation...

..The low incidence of pediatric urinary calculi, along with the high cost of lithotripsy units, has limited the use of extracorporeal shock wave lithotripsy in pediatric institutions...

..The incidence of calculi in augmented bladders has been reported in up to 50% of cases. We analyzed our experience with stone formation in this population to assess risk factors and outcomes...

..However, many surgeons continue to use an intravesical technique when extensive ureteral tailoring is required in the case of primary megaureter. We present our experience and outcomes with these techniques...

..We present our experience with a pediatric population and compare it to all the other pediatric renal transplants done at our institution...

..We analyzed the records of patients with posterior urethral valves to determine risk factors that might be predictive of ultimate renal failure...

..We report our long-term outcomes and experience in this challenging patient population...

..To determine which risk factors help predict recurrent stone formation. Urinary stone disease is relatively rare in children. At our institution, a full urinary metabolic evaluation is initiated after the first stone episode...

..The purpose of this study was to assess the safety of this therapy...

..We report our experience and compare the outcomes between standard and robot-assisted laparoscopic pyeloplasty to treat ureteropelvic junction obstruction in children...

..Endoscopic injection should be considered first line treatment for this situation...

..We reviewed our experience with dextranomer/hyaluronic acid injection, and determined the incidence of and risk factors for postoperative urinary tract infection...

..We determined the incidence of urinary stone risk factors in pediatric patients with urolithiasis...

..The most commonly reported complication has been stomal stenosis of the conduit. We report our experience with the use of the MIC-KEY gastrostomy button for the management of this complication...

..A low pressure urinary reservoir optimizes the chance of graft survival and may slow native kidney death. We evaluated whether the renal deterioration rate is affected by augmentation cystoplasty...

..Robotic-assisted laparoscopy can permit excellent exposure for an oncologically-sound resection, in this case a partial nephrectomy, as well as an extended lymph node dissection...

..Intraoperative placement and confirmation of ureteral stent position can be cumbersome with the robotic arms in place. We present a technique of percutaneous antegrade stent placement that is reliable with minimal morbidity...

..All patients are continent of urine. CONCLUSIONS: Our long-term data confirm that severe bladder dysfunction can be managed safely and effectively with continent urinary reconstruction in children with ESRD...

....

..We present our experience performing ureteroscopy in prepubertal children...

..However, high grade ureteroceles were more likely to require a secondary operation unless an initial lower tract reconstruction was performed...

..We present our experience and outcomes with end cutaneous ureterostomy as a temporizing adjunct to future ureteral reimplantation...

..To assess the efficacy of perioperative antibiotics in decreasing post-operative morbidity among patients undergoing tonsillectomy or adenotonsillectomy...
