Background And Purpose: Open stone surgery nowdays is rare. However, some patients who are treated today have in the past undergone open nephrolithotomy. The aim of this study was to determine the possible impact of open nephrolithotomy on the efficacy and morbidity of subsequent percutaneous nephrolithotomy (PCNL).

The percentage of positive cells in the area of greatest staining was recorded as the TII-alpha index. TII-alpha nuclear staining was positive in all the samples except one.

Study Design: Histologic sections from 53 consecutive papillary bladder neoplasms were stained immunohistochemically for topo II-alpha expression. There were 18 (33.
This is a short report on a splenic metastasis from renal cell carcinoma. Previously, the patient had renal carcinoma removed by nephrectomy. The diagnosis of metastasis was based on morphology and immunohistochemistry.

Our objectives were to evaluate bladder tissue and adjacent organs during and following hyperthermia treatment. An intravesical catheter equipped with a radio-frequency antenna (Synergo SB-TS 101.

The study group consisted of 102 patients who underwent surgery for RCC between the years 1990 and 1997 in our institute with a mean follow up period of 81.3 months.
