Objective To evaluate the efficacy and safety of simultaneous bilateral super-mini percutaneous nephrolithotomy (SBSMP) in the treatment of preschool children and infants with bilateral upper urinary tract stones. Methods The clinical data of 10 pediatric cases with bilateral upper urinary tract stones treated with SBSMP during Oct.2015 and Jan.2017 were retrospectively analyzed. Results Altogether 9 cases successfully completed SBSMP,while 1 terminated the procedure due to puncture difficulties on the second side of the operation.The average operation time was (41.4±13.78) min.No fever occurred after the operation,and no blood transfusion was needed during or after the operation.Anuria happened in 1 case with tubeless SBSMP due to the falling-off of the uretral stent.After diuretics were given and the stiches were removed from the incision to drain urine,the child recovered well without any other interventions.No serious complications were observed in the other 9 cases.The stone-free rate was 70 %(7/10) 1 week after the operation,and 90 %(9/10) 3 months after the operation.Recurrence was observed in 1 case 1 month after operation. Conclusion SBSMP is safe,feasible and effective in the treatment of preschool children and infants with upper urinary tract stones if performed by experienced urologists.It can significantly reduce the medical expenses and exposure to anesthesia.
