Overview of surgical treatment of urolithiasis with special reference to lithotripsy.
In the early 1980s, 2 elegant innovations were added to open surgery in the management of stones: endourology and extracorporeal shock wave lithotripsy. The decision strategy for treating stones is not yet codified and it depends on several factors, such as equipment, type and size of stones, needs of the patient and skills of the surgeon. After open stone surgery convalescence lasts approximately 4 to 6 weeks and repeated surgery is more difficult. With endourology convalescence can be reduced to a few days in an uncomplicated case, the risk of complication is approximately 10 per cent and retreatment is not more complicated. Convalescence with extracorporeal shock wave lithotripsy often is negligible and some extracorporeal shock wave lithotripsy units are run on an outpatient basis. However, as with all stone surgeries, extracorporeal shock wave lithotripsy causes renal bleeding of varying degrees. There are reports of diastolic hypertension after extracorporeal shock wave lithotripsy in up to 8 per cent of the patients. Retreatment is easy but the late consequences of retreatment are unknown. Extracorporeal shock wave lithotripsy is the dominant means of surgical management for stones in the western world; 87 per cent of our patients are treated with extracorporeal shock wave lithotripsy and 4 per cent with open surgery.
