[Long-term follow-up of nephrectomy for hypernephroma in 442 patients].

The long-term-results of 442 patients with nephrectomy because of hypernephroma are analysed with regard to preoperative findings, surgical technique and postoperative therapy. Until 1971 conventional nephrectomy was performed, since then a modification with a long incision carried medially and "blind" manual preparation of the renal pedicle has been performed. This led to better long-term-results. A table of preoperative findings of all patients who survived more than 5 years or less the 6 months respectively may predict the prognosis of the individual patient. In our series postoperative radiotherapy shows very poor results and will be abandoned. The negative influence on the immuno resistance may be one reason for this.
