NCT00873054

Brief Summary

The investigators main hypothesis is that the stone free rate will be much higher (95%) in patients treated with PCNL than patients treated with ESWL where stone free rate is (60%) to determine which treatment is safe and prevent less stone recurrence.

Outcome Measures

Primary Outcomes (1)

  • The primary objective of this study is to compare the stone-free status after Extracorporeal Shock Wave Lithotripsy (ESWL) and Percutaneous Nephrolithotomy (PCNL) for kidney stones 10-20 mm in size.

    Within 3 months of enrollment

Secondary Outcomes (1)

  • A secondary objective is to assess the morbidity associated with use of the procedures i.e. any minor or major complications within 3 months of initial treatment.

    Within 3 months of enrollment

Study Arms (2)

1 ESWL

In this procedure,scope will be placed inside bladder and a plastic tube (stent) will be left to drain the kidney on the affected side in a routine manner. Next the patient will be transferred to a separate room and sound waves will be aimed at the center of the stone until the stone is broken into pieces.

2 PCNL

In this procedure,scope will be placed inside bladder and a plastic tube (stent) will be left to drain the kidney on the affected side in a routine manner. Next, a small (1cm) cut will be made in the back and a tube will be placed into the kidney. Through this tube a small camera will be placed inside the kidney and break the stone into many pieces and remove them through the same tube. All fragments that can be seen will be removed. A different plastic tube (drain) will be placed through the cut and into the kidney and left in place for 5-7 days.

  • Patients of both sex with age greater than 18 years to 90 years
  • Stone burden between 10 and 20 mm diagnosed by CT scan
  • Patient must be agreeable to randomization between shock wave lithotripsy and percutaneous stone removal

You may not qualify if:

  • Patients with bleeding diathesis or taking anti-platelet or anti-coagulant medication
  • Patients who are pregnant based on routine pre-operative pregnancy testing
  • Patients with skin to stone size greater than 12 cm (measured routinely on CT scan)
  • Patients with either Horseshoe kidney, transplant kidney or a solitary kidney
  • Patients with ureteral calculi
