Summary

Upper ureteric stones can be treated using extracorporeal shock wave lithotripsy or ureteroscopy. Extracorporeal shock wave lithotripsy breaks the stone using shock waves delivered from outside the body, whereas ureteroscopy involves passing a small instrument through the urinary tract to locate and fragment the stone.

This randomized controlled trial compared the effectiveness and safety of these two treatments in adults with a single upper ureteric stone smaller than 10 mm and a stone density of 1000 Hounsfield units or less. Participants were assigned to receive either extracorporeal shock wave lithotripsy or semirigid ureteroscopy. The main outcome was complete stone clearance on non-contrast computed tomography four weeks after completion of the assigned treatment. Pain relief, number of treatment sessions and treatment-related complications were also assessed.

Interventions

PROCEDURE

Extracorporeal Shock Wave Lithotripsy

ESWL was performed using the MODULITH SLX-F2 lithotripter at 60-120 shocks per minute, an energy setting of 1-9 kV and approximately 2500-3000 shocks per session. Each session lasted approximately 30-60 minutes. Up to three sessions were permitted, with at least 48 hours between sessions.

PROCEDURE

Semirigid Ureteroscopy

Semirigid ureteroscopy was performed under general anesthesia using a 6.5-7.5 Fr ureteroscope. Stones were fragmented using the Swiss LithoClast Master pneumatic lithotripsy system with a 1-1.2 Fr probe. Fragments were removed using a Dormia basket or grasping forceps when required. A double-J ureteric stent was inserted in every participant and subsequently removed according to clinical assessment.
