Dusting vs Fragmentation Laser Cystolithotripsy for Pediatric Bladder Stones
Sponsor: Beni-Suef University
Summary
Bladder stones are a clinically relevant pediatric urological condition that may require endoscopic treatment. Transurethral Holmium:YAG laser cystolithotripsy is a minimally invasive option for selected children with bladder stones. This prospective randomized trial will compare two Holmium:YAG laser strategies during transurethral cystolithotripsy in children with a single bladder stone less than 3 cm: dusting and fragmentation. Children will be randomized to undergo laser dusting or laser fragmentation during transurethral cystolithotripsy. The primary outcome is total operative time. Secondary outcomes include laser time, need for active fragment extraction, endoscopic stone-free status at the end of the procedure, ultrasound-assessed stone-free status during follow-up, intraoperative complications, postoperative urinary symptoms, urinary tract infection, need for postoperative catheterization, and hospital stay.

Interventions
Dusting Holmium:YAG Laser Cystolithotripsy
Transurethral Holmium:YAG laser cystolithotripsy using a dusting strategy with planned laser settings of 0.5-0.8 J and 10-15 Hz, aiming to reduce the bladder stone into fine particulate debris and tiny fragments with minimal need for active fragment extraction.
Fragmentation Holmium:YAG Laser Cystolithotripsy
Transurethral Holmium:YAG laser cystolithotripsy using a fragmentation strategy with planned laser settings of 1.0 J and 6-10 Hz, aiming to produce visible extractable stone fragments of approximately 2-5 mm, with active fragment removal when needed.
