[Nephrolithotomy in the treatment of severe nephrolithiasis].

Nephrolithotomy results are available for 63 patients with coral and multiple nephroliths operated in 1990-2002. These patients underwent 64 operations (one patient with bilateral nephrolithiasis had 2 consecutive nephrolithotomies within a month). The sites preferable for transverse nephrolithotomy are described and validated. Ligation of the renal artery with pharmacological antiischemic protection of the kidney with lasix and verapamil was performed in 40 cases.
