87腎の珊瑚樹状結石のESWLを主体とした治療結果について報告した。病歴,結石の形状,結石面積,腎盂腎杯面積など治療成績に影響すると思われる事項を抽出し,相反する治療経過をとった2症例を提示したBetween August, 1987 and December, 1991, 84 patients with 87 staghorn calculi were treated mainly with extracorporeal shockwave lithotripsy (ESWL) using a Dornier HM-3 improved lithotriptor. Patients were 38 men (38 renal units, mean age 54.9 years) and 46 women (49 renal units, mean age 54.3 years). Staghorn calculi were divided into 2 types; 54 units of complete type (mean stone area 9.2 cm2) and 34 units of incomplete type (mean stone area 5.5 cm2). Patients with complete type were treated with 3.6 sessions and 7,779 shock waves on average and 31.6 days for hospitalization was required, while patients with incomplete type were treated with 2.4 sessions and 5,288 shock waves on average and 15.7 days for hospitalization was required. After treatment, the excellent rate was 47.2% for the complete type and 44.1% for the incomplete type. After the monotherapy of ESWL the excellent rate was 46.9% and after the combined therapy with percutaneous nephrolithotripsy (PNL) and/or percutaneous nephrostomy (PCN) it was 43.5%. We considered that the ESWL monotherapy for staghorn calculi was not feasible in patients with a large stone volume, with severe hydrocalices, with cystine stones and with so-called "complex staghorn calculi".
