[The Result of Aortic Valve Plasty with Autologous Pericardium Using Sawazaki's Template].

The autologous pericardial aortic valve repair technique developed by Ozaki et al., using glutaraldehyde-treated autologous pericardium, has demonstrated superior durability to bioprosthetic valves.

Results of extracorporeal shock wave lithotripsy for the treatment of upper urinary tract stones.

The treatment results of 697 renal units in 687 patients treated for upper urinary tract stones using a Piezolith 2500 at the Ageo Central General Hospital during the 5-year period between August 1999 and July 2004 were analyzed. The stone-free rate and the success rate were calculated according to the stone size and location. Univariate and multivariate logistic regression analyses were performed to estimate the effect of the patient age, sex, affected side, stone location and stone size on the stone-free rate and the success rate.
