Introduction: The treatment preserving the kidney for upper urinary tract (UUT) transitional cell carcinoma (TCC) is still controversial. We aimed to elucidate the results of open conservative surgery and compare them with the results of radical nephroureterectomy (RNU). Patients and Methods: The study included 107 patients with UUT TCC treated by open conservative surgery (21 patients) or nephroureterectomy (86 patients). Epidemiological, clinical and pathological characteristics of patients as well as 5-year survival rates were compared between groups. Results: Patients treated by conservative surgery had a significantly higher rate of bilateral tumors (38% vs. 3%, p = 0.0001) and smaller tumor size than those treated by radical operations (2.60 ± 1.24 vs. 3.99 ± 3.94 cm, p = 0.060). Five-year survival rates for patients treated by conservative and radical surgery were 59 and 55%, respectively. Within the group of patients treated by conservative surgery, 5-year overall survival rates of patients operated due to imperative and elective indications were 41 and 75%, respectively. In univariate analysis, RNU was a statistically significant predictor of poorer outcome of the disease in comparison with conservative surgery (HR = 2.2, 95% CI 1.1-4.6, p = 0.030). Conclusions: The mode of operation affects the outcome of UUT TCC patients, in addition to factors such as tumor grade, stage and size. © 2009 S. Karger AG, Basel.

Although tuberculosis (TB) is a curable disease, it continues to be one of the leading infections associated with death in the world. Extra-pulmonary TB (EPTB) occurs in approximately 10% of the total cases, presenting with lymph nodes, pleura, bone and genitourinary tract as the most common locations. Genitourinary tuberculosis, the second most common EPTB, is very difficult to diagnose unless there is a high index of suspicion. Isolated TB orchitis or prostatitis without clinical evidence of renal involvement is a rare entity among genitourinary tuberculosis. We presented the first reported case of TB prostatitis and orchitis associated with pulmonary TB and the presence of an acute massive caseous pneumonia in an immunocompetent man. Despite the anti-TB therapy, the patient presented a rapid progression of disease and deterioration of general conditions taking to death, which occurred four days after TB treatment had started. Disseminated TB is a relatively uncommon cause of acute massive caseous pneumonia; however, there should always be suspicion of the disease, since it is a potentially treatable cause. This rare case supports the assertion that TB should be considered as an important differential diagnosis of genitourinary tumors irrespective of evidence of active TB elsewhere in the body. © 2017, Instituto de Medicina Tropical de Sao Paulo.

The management of high-grade (HG) nonmuscle-invasive bladder cancer (NMIBC) continues to be a serious clinical problem. The role of many factors related to efficacy of Bacillus Calmette-Guérin (BCG), which is the most useful intravesical agent for these tumors, is still unknown. This study investigated the prognostic value of tumor location in high-grade non-muscle-invasive bladder cancer. Seventy-four patients with HG non-muscle-invasive bladder cancer, without carcinoma in situ (CIS), were treated by transurethral resection of bladder tumor (TURBT). Twenty-eight patients received adjuvant BCG therapy after TURBT. The relation between tumor location and the recurrence capacity was estimated using a Cox regression model. Our results suggest that tumor location is an important prognostic factor for BCG-therapy response in patients with high-grade non-muscle-invasive bladder cancer. Tumors in the bladder neck might have a higher risk of recurrence after intravesical immunotherapy. In addition, tumors in the lateral and posterior bladder walls might be at higher risk of recurrence when treated by TURBT alone. © Springer Science+Business Media, LLC 2011.

The case of giant renal cyst measuring 30 cm, accompanied by abdominal swelling and erythrocytosis, is presented. A 45-year-old male presented with large abdominal mass, atrophic left kidney, hypertension, and erythrocytosis. The patient underwent multiple preoperative phlebotomies, open extirpation of the cyst, and nephrectomy. After the surgery, erythrocytosis ceased completely, blood pressure became normal without any medications whereas function of the remaining kidney was stable. The giant renal cysts measuring more than 15 cm are extremely rare. However, they can cause erythrocytosis and hypertension very frequently, especially in the case of cysts originating from the proximal tubule. To our knowledge, this is the largest renal cyst published in the literature that caused the above-mentioned complications. © 2011 Informa Healthcare USA, Inc.

OBJECTIVE: To evaluate the characteristics and survival of patients with upper urinary tract (UUT) transitional cell carcinoma (TCC) in Serbia, followed for ≥5 years or until death. PATIENTS AND METHODS: From 1998 to 2005 we analysed 114 cases of pathologically confirmed UUT TCC, divided into two groups according to topographical characteristics, and compared their demographic, clinical and pathological characteristics. The influence of various factors on overall 5-year survival of patients with UUT TCC was also tested. The prognostic value of different variables was assessed by univariate and multivariate Cox proportional-hazard models. RESULTS: The most important change in demographic characteristics of the patients with UUT TCC in Serbia was a similar proportion of patients residing in areas of Balkan endemic nephropathy (BEN) and non-endemic areas. The median (range) follow-up was 67 (46-88) months. The 5-year probability of survival was 51.2 ± 5.8%. There was a significantly lower probability of 5-year survival for patients with a higher histological grade (P = 0.001), higher T stage (P < 0.001) and tumour size >3 cm (P = 0.001) at diagnosis. In this cohort of patients the independent predictors of a poorer outcome of the disease were being female (hazard ratio, HR, 2.2, P = 0.010), tumour size >3 cm (HR 2.8, P = 0.001) and T3 or T4 stages (HR 3.1, P = 0.001). CONCLUSION: Comparative analysis of the characteristics of UUT TCC between patients from BEN and non-endemic areas of Serbia showed similarities in demographic, clinical and pathological features. Factors that significantly influenced survival of patients with UUT TCC were being female, tumour size and tumour grade and stage. © 2007 The Authors.

Purpose: To assess the knowledge and attitudes of men in Serbia about prostate cancer (PCA) and possibilities for its early detection and treatment in 2011. Methods: This cross-sectional study included 407 men of various ages and education levels selected randomly and divided in 2 groups according to age (up to 40 and over 40 years). The assessment of knowledge and attitudes was based on a survey made up of 12 multiple choice questions conducted with direct contact with respondents from October 15th to December 15th 2011 with their voluntary consent. The results were evaluated in the total sample and between the groups. Results: Patient groups significantly differed according to knowledge about PCA treatment success (p<0.001) and stage in which PCA is most frequently detected (p<0.001) as well as according to attitudes about community-based interventions for increasing the awareness of PCA (p<0.001). Sixty-one percent of respondents over 50 years hadn't done preventive prostate examination despite recommendations. Ninety percent of all respondents believed the community-based intervention should have been implemented in Serbia to increase the men's awareness of PCA. Conclusion: The study reported lack of men's knowledge about PCA in Serbia in 2011, while there was a common agreement among men on the necessity of spreading more information about this disease. © 2019 Zerbinis Publications.

Background and Objectives: In the development of type 2 diabetes mellitus (T2DM) and its complications, genetic and environmental factors play important roles. Diabetic nephropathy (DN), one of the major microangiopathic chronic diabetic complications, is associated with an increased risk of major cardiovascular events and all-cause mortality. The present study was designed to investigate the possible modifying effect of glutathione transferase polymorphisms (GSTM1, GSTT1, GSTP1 rs1138272/rs1695, GSTO1 rs4925 and GSTO2 rs156697) in the susceptibility to T2DM and diabetic nephropathy. Materials and Methods: GSTM1 and GSTT1 deletion polymorphisms were determined by multiplex PCR, whereas GSTO1, GSTO2, and GSTP1 polymorphisms were determined by the real-time PCR in 160 T2DM patients and 248 age- and gender-matched controls. Advanced glycation end products (AGEs) were measured by ELISA. Results: Among six investigated GST polymorphisms, a significant association between the GST genotypes and susceptibility for development of diabetes mellitus was found for the GSTM1, GSTT1, GSTP1 (rs1138272) and GSTO1 polymorphisms. When the GST genotypes’ distribution in diabetes patients was assessed in the subgroups with and without diabetic nephropathy, a significant association was found only for the GSTO2 rs156697 polymorphism. Diabetic patients, carriers of the GSTM1 null, GSTT1 null and variant GSTO1*AA genotypes, had significantly increased levels of AGEs in comparison with carriers of the GSTM1 active, GSTT1 active and referent GSTO1*CC genotypes (p < 0.001, p < 0.001, p = 0.004, respectively). Conclusions: The present study supports the hypothesis that GST polymorphisms modulate the risk of diabetes and diabetic nephropathy and influence the AGEs concentration, suggesting the potential regulatory role of these enzymes in redox homeostasis disturbances. © 2023 by the authors.
