Extraskeletal mesenchymal chondrosarcoma of the kidney.

A 61-year-old woman was referred for evaluation of an incidental mass found on the right kidney.

[The use of predeposited autologous blood transfusion for radical prostatectomy].

Purpose: In reference to the cases in which radical prostatectomy was performed after storage of autologous blood, we retrospectively study the usefulness of this procedure and proper amount of blood stored.

Patients And Methods: The subjects included 62 cases in which radical prostatectomy was performed after storage of autologous blood from October, 1997 to March, 2000. As the amount of blood to be stored, either 800 ml or 1,200 ml was selected optionally as the amount of blood to be stored, and blood was stored at a rate of 400 ml once a week.
