[A method for forming a urinary bladder from the sigmoid after radical cystectomy in patients with bladder cancer].

A procedure was evolved and tested for forming a urinary bladder from the sigmoid in the course of radical cystectomy carried out for invasive bladder cancer (20). A sigmo-sigmoid anastomosis ("end-to-side") was used by means of an apparatus suture.

[Application of radiofrequency ablation for treatment of localized renal carcinoma].

An evaluation of the results of radiofrequency ablation of renal clear-cell carcinoma (pT1aN0M0) in 7 patients is presented. The longest follow-up was 26 months, the shortest--4 months. No complication was reported. A review of the literature and our own experience point to radiofrequency ablation being an effective procedure of thermotherapy for small-size peripheral renal neoplasms.

[Long-term results of endovascular treatment of metastatic renal cell cancer]. / Otdalennye rezul'taty éndovaskuliarnogo lecheniia metastaticheskogo pochechnokletochnogo raka.

The authors analyse the long-term results of treatment of 106 patients with advanced renal cell carcinoma. The patients were divided in two groups. Group 1 (42 patients) included cases with single metastatic lesion. Patients of group 2 (n = 64) had more than one site of metastases. All patients were treated by nephrectomy, embolization with chemotherapeutic agent or arterial occlusion without cytostatic drug except nine patient of group 2, who has undergone chemo and hormonal therapy. The survival according to method at treatment was studies. After occlusion satisfactory results were obtained in cases with single metastasis lesion and also in cases with many sites of metastases. Oily chemoembolization in renal cell carcinoma with distant metastases has given better results as compared with the embolization without chemodrugs. We conclude that endovascular method of treatment is an alternative to the traditional nephrectomy in palliation of renal cell carcinoma.

[The angiographic evaluation of the collateral circulation in an inoperable kidney tumor after embolization]. / Angiograficheskaia otsenka kollateral'nogo krovoobrashcheniia inoperabel'noi opukholi pochki posle émbolizatsii.

Collateral circulation in renal tumor was measured at control angiography 2-22 months after therapeutic embolisation in 32 patients with inoperable cancer of the kidney. Collateral circulation was absent in 38% of patients. 20 patients (62%) had 36 collaterals. The essential role in the reestablishment of arterial supply to the tumor belonged to collaterals from the lumbar, adrenal, accessory arteries as well as to recanalization of the main renal artery trunk. Embolization of the collaterals was performed in 18 patients. It is inferred that after therapeutic embolisation of the renal artery the majority of the patients develop collateral supply of the tumor. Embolisation of the collaterals can be performed 6-12 months after the embolization at control investigation. For detailed evaluation of the tumor revascularization an additional angiographic examination at that time would be beneficial.

[X-ray intravascular surgery in oncologic urology]. / Rentgenoéndovaskuliarnaia khirurgiia v onkourologii.

The outcomes of treatment with intravascular embolization/chemoembolization and regional chemotherapy were analyzed in 862 patients with tumors of the kidney (n = 568), urinary bladder (n = 232) and prostate (n = 62). In renal cancer, the five-year survival rates after mechanical embolization followed by nephrectomy were 51%, those after chemoembolization and surgery, 77%. In inoperable cases, they were 3 and 25%, respectively (p < 0.05). The findings with new procedures of iron drug embolization, followed by local hyperthermia, are much more promising. In 90% after regional arterial chemotherapy, symptoms (pain, dysuria, hemorrhage) of bladder cancer ceased. With embolization, successful hemostasis was performed in 80% of massive bleedings from the bladder tumor and significant reductions of blood loss were achieved after transurethral resection of prostatic carcinoma/adenoma. X-ray endovascular surgical techniques play an important role in the treatment of oncologic urological diseases.

[Long-term results and perspectives of various radio-endovascular embolization in the treatment of patients with renal parenchyma cancer]. / Otdalennye rezultaty i perspektivy razlichnykh vidov rentgenoéndovaskuliarnoi émbolizatsii v lechenii bolnykh rakom parenkhimy pochki.

Various types of x-ray endovascular embolization were carried out in 256 patients with renal parenchymatous carcinoma over the period of 1979 to 1991. Iodolipol chemoembolization with dioxadet, a fat-soluble preparation, significantly improved three- and five-year cumulative survival of operable patients to 82.5 and 77%, respectively, vs. embolization without dioxadet, when only 58% of patients survived for three and 51% for five years. In inoperable patients five-year survival after fatty chemoembolization was 24.5% vs. null in the group administered embolization without dioxadet. Ferrochemoembolization appears still more promising.
