Background/aim: This study was designed to compare the outcomes of mini-percutaneous cystolithotomy (mPCL) and transurethral cystolithotripsy (TUCL) in treating bladder stones in preschool-aged children (≤6 years old). Materials and methods: Twenty-four patients treated with mPCL and 28 patients treated with TUCL for bladder stones were compared retrospectively. The operative and postoperative outcomes of both groups were analyzed. Results: The mean age and gender distribution were similar between the groups. The mean stone size was 16.5 ± 0.5 mm for the mPCL group and 14.9 ± 5.7 mm for the TUCL group (p = 0.318). The mean operative time was 41.1 ± 9.9 min for the mPCL group and 39.0 ± 12.3 min for the TUCL group (p = 0.182). Catheterization times and hospitalization times were statistically significantly longer in the mPCL group (p = 0.000). The rate of urinary retention after urethral catheter removal was significantly higher in the TUCL group (p < 0.05). Reintervention was performed for one patient in Group 1 due to urinary leakage and for five patients in Group 2 due to urinary retention. The stone-free rate (SFR) after a single procedure was 100% in the mPCL group and 89.3% in the TUCL group (p = 0.099). After auxiliary procedures performed for three patients, the overall SFR also reached 100% for the TUCL group. Conclusion: Both mPCL and TUCL are effective methods in the treatment of bladder stones of 20 mm.
