ABSTRACT
During clinical tests of a new Russian [symbol: see text]K-Kom[symbol: see text]akt 9701[symbol: see text] lithotriptor, the Urological Unit of the Moscow Regional Research and Clinical Institute performed 73 sessions of telemetric shock-wave lithotripsy (TIWL) in 43 patients with urolithiasis (20 females and 23 males whose age ranged from 23 to 78 years). The tests indicated that the new device meets all present medical and engineering requirements for lithotriptors having an ultrasound stone-picking-up system and has some advantages over the analogues made in foreign countries in both medical and engineering indices. The device provides good images of renal calculi and destroys them effectively, of peripelvic and intramural portions of the ureter, and the urinary bladder. A positive effect of TIWL was achieved in 37 patients (calculous fragments moving away in full), minor calculous fragments remained in 6 patients (their treatment is under way). No complications associated with the action of shock waves generated by the [symbol: see text]K-Kom[symbol: see text]akt 9701[symbol: see text] lithotriptor on the kidney and adjacent organs were observed during the clinical tests. Post-TIWL control follow-ups (within the first 24 hours to 6 months after TIWL) revealed no noticeable structural changes in the renal parenchyma or worse renal function.
