[Our experiences with urate I in bladder stones].

It is reported on the experiences with the electrohydraulic lithotripsy in 122 patients. The indications, contraindications and regulations for the intervention are shown and it is referred to their significance for a successful and dangerousless operation. This fact is emphasized by two own cases with intraoperative complications. In the opinion of the authors the electrohydraulic lithotripsy is the method of choice in the treatment of vesicular calculi in an adequate indication and in the department of the authors it has fully restricted the mechanical lithotripsy.

The clinical value of lymphangiography: are the nodes surrounding the obturator nerve visualized?

Twenty-five patients subjected to pelvic node dissection for urologic malignancies underwent bilateral pedal lymphangiography preoperatively. Postoperatively, 50 samples of the nodes selectively removed from the regions surrounding the obturator nerve were radiographed. All 50 samples revealed the presence of radiopaque dye. The lymph nodes surrounding the obturator nerve represent the first point of lymphatic metastases in carcinoma of the prostate and the bladder. Their visualization by lymphangiography emphasizes the importance of such a diagnostic study for the correct clinical staging of these diseases. The lymphatic anatomy of the pelvis is reviewed and compared to the radiological findings in lymphangiography.

In situ identification of lymphoreticular cells in benign and malignant infiltrates by membrane receptor sites.

Immunologic membrane markers have been utilized for the in situ identification of lymphoreticular cells within lymphoreticular tissues and in inflammatory and neoplastic lymphoreticular infiltrates of the skin. Frozen sections were layered with untreated sheep red blood cells (SRBC) for the detection of the E receptor on T cells, SRBC coated with 7S antibody for the detection of the Fc receptor (IgGEA) and SRBC coated with 19S antibody and complement (IgMEAC) for the detection of the C3 receptor. In normal lymphoreticular tissue, IgGEA selectively bound to areas colonized by macrophages, IgMEAC to B-dependent areas, whereas E showed no adherence. In chronic lymphatic leukemia, a predominant and selective adherence of IgMEAC was found in lymphoreticular organs which supports the B-cell nature of the neoplastic cells; in leukemic reticuloendotheliosis a selective IgMEAC adherence was observed and this favors a monocytoid origin of the hairy cells. Adherence of any indicator cell was practically absent from skin infiltrates of mycosis fungoides, which represents an additional piece of evidence for the T-cell nature of this disease process. In psoriasis, a considerable binding of IgGEA was observed, whereas IgMEAC did not adhere at all. This result indicates that the lymphocytic part of the infiltrate in this disease consists mainly of T cells.

[Therapy of solid tumors using high-dose methotrexate and citrovorum factor].

Methotrexat (250-1100 mg/m2) was administered to 38 patients with malignant tumors by infusion of either 6 hours or of 75 minutes duration. MTX-infusion and continued at 3-6 hours interval for Citrovorum factor rescue was started 2 hours after 24 to 72 hours. 7 different MTX doses and rescue schedules were tested. It could be shown that MTX in the dose range used is effective in various tumors when CF-rescue is not higher than 7% of the administered MTX-dose, only occasionally therapeutic success was observed with higher doses. In the group of patients where CF-rescue was lower than 7% of the MTX dose on 9/14 patients objective tumor-regressions could be achieved. Conclusions drawn are discussed and the necessity of further investigations is emphasized.

Combination radical surgery and multiple sequential chemotherapy for the treatment of advanced carcinoma of the testis (stage III).

Nineteen patients with advanced testicular carcinomas (Stage III) were treated by a combination of multisequential chemotherapy with vinblastine, bleomycin, platinum, adriamycin, cytoxan, actinomycin D, and reductive surgery. Of the sixteen patients who were operated on 10 patients are alive and free of disease from 5 to 15 months. Two patients are alive with residual disease and four patients died. (Three were free of malignant tumor and one had residual malignant disease.) Three patients are still receiving preoperative chemotherapy. Pathology reported benign tumors in 8 out of 16 patients operated on. All these patients were previously treated with multiple chemotherapy. Several facts emerge from this study: (1) the great effectiveness of the combination of multisequential chemotherapy and reductive surgery to produce complete clinical remission in advanced testicular carcinomas (63.6%, 13 out of 19 patients); (2) the possibility of benign transformation of these tumors (50%, 8 out of 16); (3) the importance of the second-look surgery in testicular tumors.

Hemangiopericytoma of the Urinary Bladder: a case report and review of the literature.

A case of hemangiopericytoma arising in the urinary bladder is presented. Initial symptoms included hematuria and frequency of urination. Hemangiopericytoma is a vascular tumor of pericyte origin which occurs primarily in several organs and can be benign or malignant. Reports in the literature of genitourinary system involvement are reviewed. It is concluded that genitourinary tumors of this type should be considered malignant and treated aggressively.

Hemodialysis in patients with carcinoma.

All patients who underwent hemodialysis as part of their treatment for cancer at Roswell Park Memorial Institute from 1965 to 1974 were retrospectively studied to determine the value of hemodialysis in cancer patients. Approximately 25% (8 cases) lived 5 weeks or longer in spite of advanced renal failure and carcinoma with no severe complications. The longest survivor is still alive after ten years.

Sisomicin in urinary tract infection: Tolerance and efficacy study.

Twenty-one patients with gram-negative urinary tract infections were treated with sisomicin, a new aminoglycoside antibiotic. Bacteriologic cure was achieved in 62 per cent of patients, and improvement in another 33 per cent. Mild transient elevation of serum creatinine occurred in 3 patients. No other toxicity was observed. Further clinical trials with more frequent dose administration and in combination with other antibiotics is suggested.
