Three hundred and ninety five cases in 358 consecutive patients (male-232, female-126) with renal and ureteric stones were treated with extracorporeal shockwave lithotripsy (ESWL) from March to November 1988. They either had ESWL alone, or in combination with stone manipulation or debulking percutaneous nephrolithotripsy (PCNL). Seventy five percent of the stones were found in the pelvicalyceal system and 25% in the ureter. Seventy-six percent of the stones were less than 25mm size. Two hundred and ninety (79%) cases were followed up to three months. Two hundred and forty nine (85.9%) cases were stone free and 36 (12.4%) had residual sand less than 3mm size. Five (1.7%) cases failed to fragment with ESWL monotherapy and were salvaged by either percutaneous or ureteroscopic intervention. None of the cases required any open surgery intervention.
