Urinary Bladder Calculi

This study evaluates and compares two minimally invasive surgical approaches for treating bladder stones in adult patients: transurethral cystolithotripsy (TUCL) and percutaneous cystolithotripsy (PCCL). Urinary bladder stones are commonly managed using endoscopic techniques to avoid the morbidity of open surgery. TUCL accesses the bladder through the natural urinary channel (urethra), whereas PCCL accesses the bladder directly through a small puncture in the lower abdomen above the pubic bone. While both approaches are effective, comparative data in adult populations remain limited. Eligible participants are randomly assigned to receive either TUCL or PCCL. The primary goal is to compare stone clearance rates and operative times between the two procedures. Secondary objectives include comparing surgical complication rates, duration of postoperative urinary catheterization, and length of hospital stay.
