Current treatment of infection stones in high risk patients

During a 12-month interval we removed struvite calculi from 20 kidneys in high risk patients, including 10 kidneys with branched stones. Endourological methods were used for primary treatment of 16 renal units and 12 (75 per cent) are free of stones. Endoscopic removal of residual stone fragments also was successful in 2 of 3 patients following a conventional open operation. The remaining stone fragments were located in isolated calices. Endourology presently is an integral component of a total therapeutic program for management of complicated patients with struvite calculi.
