Eight cases of renal pelvis irrigation with stone solvents were reported. 1. The treatment was carried out in 7 renal staghorn calculi and 2 residual calculi after pyelolithotomy. The renal function was poor in 5 cases and 2 cases had single kidney. 2. Composition of the stones revealed 3 struvite, 2 struvite plus apatite, 1 cystine and 1 cakium carbonate. 3. EDTA was used in 5 cases, G in 2, and the combined in 1. 4. Stone solvent was irrigated by means of nephrostorny in 2 cases and ureteral catheterization in 6. 5. Out of 8 calculi, 1 (struvite) was completely dissolved. Three (1 calcium carbonate, 1 struvite, 1 struvite plus apatite) were partially, and 2 (1 struvite, 1 struvite plus apatite) were slightly dissolved, but 2 (1 struvite plus apatite, 1 cystine) remained unchanged. 6. Complications due to this treatment were as follows: fever (moderate 1, slight 5), flank pain (severe 2, slight 4), and/or vesical irritation (sever 1, moderate 1, slight 3). Symptoms were severe in 5% EDTA cases, but not remarkable in solution G cases.
