Item type:Publication, POSTOPERATIVE SERUM CREATININ LEVEL IN TWO DIFERENT HYDRATION REGIMES IN LIVING DONOR KYDNEY TRANSPLANATATION(Department of Anaesthesia and Reanimation, Faculty of Medicine, Ss. Cyril and Methodius University, Skopje, Macedonia, 2017-04); ; ; Introduction: Early graft function is very important and can be achieved with adequate intraopeartive perfusion characteristics of the graft and urine output. The goal of this study was to examine the influence of targeting central venous pressure (CVP) on early graft function. Material and methods: After approval of Ethical committee of the Medical Faculty-Skopje, we obtained inform consent of 60 patients, ASA 2-3 undergoing renal transplantation of livingrelated person in the Clinic of Urology – Skopje. A prospective clinical study was performed in the period of 2 years. Patients were divided into 2 groups of thirty patients : group A receiving normal saline intraoperatively targeting for CVP to 15 mmHg until vascular clamps were off and group B receiving normal saline 10ml/kg/h. We recorded lactate at the end of the surgery, onset of diuresis and total urine output from unclamping the renal vessels to the end of the surgery in both groups and postoperative serum creatinine in 3times (3, 12, 36 hours). Results: The onset of diuresis in seconds was insignificantly longer in group B p>0,05 (p=o,31). The average value of postoperative levels of the lactate showed that in group B the levels of the lactate were significantly higher for Z=-5,79 and p<0,001 (p=0,000). We didn’t find any statistical differences in postoperative serum creatinine in both groups. Conclusion: Our study didn’t show any benefit from targeting CVP to 15 mmHg. We couldn’t find any significant difference on onset of diuresis and urine output after the unclamping the vessels. However, in the constant infusion group (group B) the level of the lactate was higher CVP. In postoperative biochemical parameters we had no statistical difference between the average values of serum cratinine. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Percutaneous Nephrostomy as a Procedure in the Treatment of Urinary Tract Obstruction - Experiences in the University Clinic of Urology in Skopje(Macedonian Academy of Sciences and Arts, 2024-04); ; Obstructive uropathy encompasses various urinary tract obstructions, leading to changes in urine flow, kidney pressure, and impaired kidney function. Predicting renal recovery from obstructive uropathy, can be challenging and necessitates treatment, as in percutaneous nephrostomy (PNS) drainage. The choice of drainage method depends on patient-specific factors and local expertise. According to the data for the Republic of North Macedonia, in the register of the European Renal Association, in the last few years, there has been an increase in the percentage of patients with obstructive nephropathy from 7.6% to 8.9% who end up on a chronic hemodialysis program. Prompt relief from urinary tract obstruction is essential to preserve renal function and prevent complications. The aim of this study is to present our initial data analysis of recent experience in the use of nephrostomies as a method for temporary or long-term resolution of obstructive nephropathy, in terms of safety and success in preserving kidney function and reducing the number of patients on hemodialysis. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study(Wiley, 2022-01); ; ; Chokleska, NSARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality (5.4 (95%CI 4.3-6.7)). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Incidence of Urinary Tract Tumours in a Two-Year Period (2010-2011) at the Institute of Pathology, Faculty of Medicine, Skopje, Macedonia(Walter de Gruyter GmbH / MANU, 2014); ; ; ; Bodganovska-Todorovska, MagdalenaWe performed a retrospective analysis of tumours of the kidneys and the lower urinary tract diagnosed at the Institute of Pathology, Faculty of Medicine, Ss. Cyril and Methodius University, Skopje, Macedonia, in a two-year period (2010-2011), with the aim of highlighting the main morphological characteristics and to present the statistical features of these tumours. All the cases were diagnosed on paraffin sections from surgical specimens routinely stained with H&E, and immunohistochemically with a panel of monoclonal antibodies. The analysis revealed a total of 755 cases, of which 166 (14%) were located in the kidney including the renal pelvis, and 649 (86%) were tumours of the urinary bladder. Twelve of the renal tumours (11.3%) were benign, and the rest were malignant tumours. Most of them were adenocarcinomas (n=77; 72.6%) and 17 cases (16%) were transitional cell carcinomas originating from the renal pelvis. The analysis of the lower urinary tract tumours showed a strong prevalence of malignant urothelial tumours (96%), with a male to female ratio of almost 4:1. Low grade morphology was a predominant feature (71.7%) and 51 cases (22.9%) were of high grade. The percentage of urothelial tumours of the kidney in our series is higher than in most of the reported series, which should lead to an expanded analysis. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Insulin Resistance, Glycemia and Cortisol Levels in Surgical Patients who Had Preoperative Caloric Load with Amino Acids(Macedonian Academy of Sciences and Arts/ Walter de Gruyter GmbH, 2015); ; ; ; Surgical stress response, results in elevated levels of anti-insulin hormones and reduced insulin secretion. This hormonal state may be detrimental for surgical patients due to the presence of insulin resistance and hyperglycemia. Additionally, pre-operative fasting favors this conditions. The aim of this study is to analyze the impact of pre-operative caloric load, with 440kJ from amino acid infusions on the levels of glucose, cortisol and insulin resistance in surgical patients.
