Speleotomy was re-evaluated in the present study with the observations in 11 cases; and a modification of Staehler's operation, “cavity constriction”, was introduced. Staehler's operation was carried out in 6 cases and “cavity con-striction” in 5 cases. In most cases the presence of cavities in the kidney was suspected on the intravenous pyelograms, and it was confirmed by retrograde pyelography combined with pneumoretroperitoneum and by aortography. After the operation, improvement in urinary findings and in the renal function was noted in several cases. Irrespective of duration of chemotherapy, tubercle bacillus was demonstrated in the cavities of 6 cases. In all cases, where cavity con-striction was carried out, postoperative fistula closed within 2 weeks, while in some cases where Staehler's operation was carried out, the fistula persisted much longer.
