What this Trial Is About
Researchers are evaluating two surgical methods for treating bladder stones in children aged 2 to 14 years. This study compares vacuum-assisted mini-percutaneous cystolithotripsy with the standard transurethral cystolithotripsy, focusing mainly on the total time taken for the operation. The research aims to provide early comparative data on safety, stone removal, recovery, and follow-up outcomes to guide future studies. Participants will be randomly assigned to one of two groups. One group will receive vacuum-assisted mini-percutaneous cystolithotripsy using a small suprapubic access point and suction to remove stone fragments during laser treatment. The other group will have transurethral cystolithotripsy using a small ureteroscope passed through the urethra to break and clear stones with laser assistance. Both procedures are done under general anesthesia. Throughout the study, children will be monitored for surgery duration, stone clearance, injury to the urethra, postoperative complications like infection or urinary leakage, pain, hospital stay, and recovery progress. Follow-up will include checking for stone recurrence or urethral issues up to six months after surgery. The study expects to help understand which method may offer better outcomes for children with bladder stones.
