Critical evaluation of treatment of staghorn calculi by percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy.
The combined use of percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy in patients with staghorn calculi has become an established treatment regimen. We evaluated the results of 90 staghorn calculi-bearing kidneys treated with such combination therapy after a mean follow-up of approximately 2 years. A total of 69 kidneys (76.7 per cent) became free of stones at some point after treatment. However, due to stone recurrence this number decreased to 55 kidneys (61.1 per cent) at the end of follow-up. Patients who had undergone a previous open operation on the stone-bearing kidney showed less favorable results than the over-all group. When our results were compared to reported data on open surgery or percutaneous nephrolithotomy alone even better results may have been obtained by such treatment modalities. However, our data indicate that percutaneous stone debulking combined with further destruction of residual stone fragments by shock wave lithotripsy certainly is less invasive than an open operation and provides an alternative to percutaneous treatment alone, which can yield comparable results.
