Surgical Management of Vesical Stones in Children: A Comparison Between Open cystolithotomy, Percutaneous Cystolithotomy and Transurethral Cystolithotripsy with Holmium-YAG Laser

Bladder stone in children is rare but is more common in developing countries. In recent years, the urologists have trend to minimal invasive approaches. The aim of this study, was to compare the outcomes of surgical bladder stone management in our single tertiary center.
Methods and materials: The 159 children younger than 18 years with vesical stones treated during January 2000 to January 2015 in Shohada e Tajrish hospital, Tehran, Iran that 146 subjects entered to the study. According to type of intervention, patients stratified to three groups. First group was included 80 patient’s that open cystolithotomy(OCL) was done for them, second group, 39 patients who underwent percutaneous cystolithotomy(PCCL)and third group,27 patients who treated by transurethral cystolithotripsy with holmium-YAG laser(TULL). Demographic data, operation time, hospital stay, and post operation complications were extracted and compared between groups.
Mean age was 8.3±5.1 years (8.6±5.1, 6±4.2 years for boys and girls, respectively). Mean stone size was 2.76±1.07 cm that was not significant between three groups but it was larger in OCL group. Mean operative time was 29.15(±7.12) min that in separate, mean operative time in TULL was significantly higher than PCCL and OCL respectively (36.3±5.97, 30.54±5.27 and 26.06±6.32 min/P:0.000). Mean hospital stay in OCL group was 3.55±1 day that was higher than PCCL and TULL groups significantly (P=0.000).
based on our study, Ho:YAG lithotripsy is a safe with high success rate minimally invasive management method for children bladder calculi if proper equipment was available and done in expert hands.
