Aim: To develop the method for extracorporeal partial nephrectomy under pharmaco-cold ischemia without ureter intersection with orthotopic replantation of renal vessels for RCC., Material and Methods: The study included 37 patients with morphologically confirmed RCC pT1a-Т3bN0M0-1G1-3 with intraparenchymal and central location of the tumor in cases of single kidney, comorbidity of contralateral kidney and kidney on the side of lesion., Results: Mean surgery time was 413.97±89.14 minutes. Mean time of warm ischemia was 8.39±4.75 minutes, cold ischemia - 151.41±41.29 minutes. Intraoperative and postoperative complications were detected in 3 (8.1%) and 18 (48.6%) patients respectively., Conclusion: Extracorporeal partial nephrectomy under pharmaco-cold ischemia without ureter intersection with orthotopic replantation of renal vessels for RCC is a relatively safe organ-sparing treatment. It provides resection of large tumors with any location under prolonged cold ischemia without ureter intersection.

Contemporary possibilities of organ-sparing therapy for borderline ovarian tumors are considered. World data was analyzed on recurrence rates and fertility rates after different methods of conservative surgery. The experience with ultra-conservative surgery in patients with bilateral borderline ovarian tumors at the Onco-Gynecological clinic of the P.A. Herzen Moscow Research Oncology Institute is presented.

Municipal multidisciplinary hospital No 2, Saint-Petersburg The article presents results of 9 extracorporal renal resections for carcinoma with the following autotransplantation. The mean duration of operation was 297.8 minutes and the mean period of hypothermic ischemia consisted of 112,6 minutes. A postoperative follow-up (max 4 years) revealed that there isn't noted any dissemination of the tumor and functional condition of the transplanted kidney was satisfactory. The extracorporal renal resection with the following autotransplantation could be performed according to absolute indication of organ saving and technical impossibility of renal resection in situ. In the case, when experienced surgeons carry out the operation, the existing risk of postoperative complications is low in spite of large volume and traumatic character of surgery in interdisciplinary approach.

It was performed a comparative analysis of parameters of early postoperative period in 318 patients with middle- and lower-ampullar cancer of rectum who underwent total mesorectumectomy and "blind" preparation of rectum. All patients were divided into 2 groups. The main group included 202 patients after total mesorectumectomy. The control group included 116 patients after "blind" preparation of rectum. Statistically significant differences in frequency of laparotomy wounds suppuration, urinary tract dysfunction and postoperative mortality were revealed. These complications were diagnosed more frequent in case of "blind" preparation of rectum. In the main group laparotomy wounds suppuration depended on sex (p<0.001, r=0.65), in the control group - on surgeon's experience (p=0.006, r=0.58), localization of tumor (p<0.001, r= -0.87) and type of surgery (p<0.001, r= -0.76). Urinary tract dysfunction after total mesorectumectomy depended on patient's sex (p<0.001, r=-0.77), after "blind" preparation of rectum - sex (p=0.002, r= -0.39) and performing of preoperative radiation therapy (p<0.001, r=0.46). In the main group none of the analyzed variables effected on the postoperative mortality. In the control group age (p=0.006, r=0.48), intraoperative blood loss (p=0.002, r=0.55), anastomosis failure (p=0.01, r=0.61), postoperative bleeding (p<0.001, r=0.88), early adhesive intestinal obstruction (p=0.006, r=0.77) effected on the mortality. It is considered that total mesorectumectomy in comparison with "blind" preparation of rectum decreases frequency of postoperative complications and mortality.
