Abstract
Open surgery for large or complex renal calculi may be difficult, particularly in patients with recurrent stones, and many require special operative techniques to preserve renal function. With the advent of percutaneous nephrolithotripsy (PCNL) and extracorporeal shockwave lithotripsy (ESWL) new approaches are now available for the treatment of these difficult cases. A review of 67 patients who presented between November 1984 and May 1986 has shown that is was possible to clear large stones in 71% of patients using a combination of PCNL and ESWL. There was no mortality; the morbidity for both procedures was low and was less than when either procedure was used alone for the treatment of complex stones.
