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.

[A case of leiomyosarcoma of the spermatic cord].

A 44-year-old male was referred to our hospital for further treatment of lung and adrenal metastases from leiomyosarcoma occurring in the left spermatic cord. He had undergone high orchiectomy 5 months before, but no adjuvant therapy was done. Although systemic CYVADIC therapy (cyclophosphamide, vincristine, doxorubicin hydrochloride, dacarbazine) was performed in our hospital, he died of metastatic disease 10 months after the initial therapy.
