RESUMO
Inflammatory myofibroblastic tumour (IMT) is a rare tumour with an intermediate biological behaviour. It usually occurs in children and adolescents, primarily in the abdomen or lungs. Histopathologically, IMT consists of spindle cells, i.e., myofibroblasts, and a variable inflammatory component. Localization in the urinary bladder is rare. We are presenting a rare case of IMT in the bladder in a middle-aged man treated by partial cystectomy. A 62-year-old man consulted a urologist because of haematuria and dysuric disturbances. A tumorous mass was detected by an ultrasound in the urinary bladder. CT urography described the tumorous mass at the dome of the urinary bladder measuring 2 × 5 cm. A smooth tumorous mass was cystoscopically observed at the dome of the urinary bladder. Transurethral resection of the bladder tumour was performed. Histopathological analysis of the specimen identified spindle cells with a mixed inflammatory infiltrate; immunohistochemical findings showed positivity for anaplastic lymphoma kinase (ALK), smooth muscle actin (SMA) and vimentin. A histopathological diagnosis of IMT was established. It was decided that the patient would undergo a partial cystectomy. A complete excision of the tumour from the dome of the urinary bladder with surrounding healthy tissue was performed. Histopathological and immunohistochemical findings of the sample confirmed the diagnosis of IMT, without the presence of the tumour at the surgical margins. The postoperative course went smoothly. IMT is a rare tumour in adults, especially localised in the urinary bladder. IMT of the urinary bladder is difficult to distinguish from urinary bladder malignancy both clinically and radiologically, as well as histopathologically. If the location and size of the tumour allow it, bladder-preserving surgeries such as partial cystectomy represent a reasonable modality of operative treatment.

Background and Objectives: One of the most frequent genetic alterations reported to date in prostate cancer (PC) is aberrant methylation of glutathione transferase P1 (GSTP1). Taking into consideration the involvement of oxidative stress in PC pathogenesis and recent advances in scientific understanding of the role of GSTP1*Ala114Val rs1138272 polymorphism in carcinogenesis, we hypothesized that this single-nucleotide polymorphism (SNP) influences the risk of PC independently of, or in combination with, other GST polymorphisms, including GSTP1*IIe105Val rs1695 or GSTM1 and GSTT1 deletion polymorphisms. Materials and Methods: Genotyping was performed in 237 PC cases and in 236 age-matched controls by multiplex polymerase chain reaction (PCR) for deletion of GST polymorphisms and by quantitative PCR for SNPs. Results: We found that carriers of either GSTP1*Val (rs1138272) or GSTP1*Val (rs1695) variant alleles had a PC risk compared to individuals with both referent alleles (OR = 4.93, 95%CI: 2.89-8.40, p < 0.001 and OR = 1.8, 95%CI: 1.19-2.73, p = 0.006, respectively). Additionally, in a haplotype analysis we found that individuals with GSTP1*C haplotype, represented by both variant alleles (GSTP1*Val rs1695 + GSTP1*Val rs1138272), had a 5.46 times higher risk of PC development compared to individuals with the most frequent haplotype (95%CI = 2.56-11.65, p < 0.001), suggesting a potential role of those variants in PC susceptibility. A regression analysis on the number of risk-associated alleles per individual (GSTM1*active, GSTT1*null, GSTP1*Val rs1695 and GSTP1*Val rs1138272) showed a significant increase in the risk of developing PC, from 3.65-fold in carriers of two risk alleles (95%CI = 1.55-8.61, p = 0.003) to an approximately 12-fold increase in carriers of all four risk alleles (95%CI = 3.05-44.93, p < 0.001). Conclusion: Prostate cancer may be influenced by multiple glutathione transferase (GST) polymorphic genes, especially GSTP1, highlighting the role of gene-gene interactions in human susceptibility to this cancer.

PURPOSE: To assess the treatment outcome of pT1a renal tumors, comparing overall survival (OS) in patients treated with radical nephrectomy (RN) and partial nephrectomy (PN), and to examine the rate of utilization of PN in a tertiary institution in Serbia. METHODS: Included were patients treated for pT1a kidney tumors with open RN or open PN during 1996-2013. The inclusion criterion was the pathological tumor stage T1a. Exclusion criteria were higher pathological stages, metastatic presentation, or imperative indications for partial nephrectomy. Patients were followed-up every 3 to 4 months for the first year after surgery, every 6 months until the 5th year, and annually thereafter. RESULTS: 286 patients were included in the study, and PN was performed in 177 (61.9%) of them, whereas RN was performed in the remaining 109 (38.1%). The median follow- up for the entire group was 42.0 months (interquartile range 74.5). There were no statistically significant differences between groups in cancer-specific survival (CSS) (log-rank=0.506; p=0.477). Patients selected for RN were more likely to be older, symptomatic at presentation, and have larger tumors. There was no statistically significant difference in OS between the two groups (log-rank=2.616; p=0.106). In 1996, 20% of the patients were treated with PN; this number increased to 88% in 2013. CONCLUSION: We did not find OS advantage for PN compared to RN in the setting of a developing country. The use of PN is increasing and is now utilized for â¼90% of pT1a renal tumors.

In recent years, the focus of numerous studies has been the predictive value of inflammatory and nutritional parameters in oncology patients. The aim of our study was to examine the relationship between the inflammatory and nutritional parameters and the histopathological characteristics of patients with bladder cancer. A retrospective study included 491 patients who underwent radical cystectomy for bladder cancer between 2017 and 2021. We calculated the preoperative values of the neutrophil-to-lymphocyte ratio (NLR), the derived neutrophil-to-lymphocyte ratio (dNLR), the systemic immune-inflammation index (SII), the systemic inflammatory response index (SIRI), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR), the prognostic nutritional index (PNI), and the geriatric nutritional risk index (GNRI). Statistically significant positive correlations were observed between NLR, dNLR, SII, SIRI, and PLR and the pathological stage of the tumor. We observed statistically significant inverse correlations for LMR, PNI, and GNRI with the tumor stage. SIRI was identified as an independent predictor of the presence of LVI. dNLR was identified as an independent predictor of positive surgical margins. GNRI was identified as an independent predictor of the presence of metastases in the lymph nodes. We noticed the predictive value of SIRI, dNLR, and GNRI in the pathology of bladder cancer patients.

Testis cancer (TC) is the most common malignancy of young men. Current evidence from studies, alongside genetics and hormonal status, suggests a significant role of toxic metals, cadmium (Cd) and lead (Pb), in the origin and development of TC. Besides oxidative stress and endocrine disruption, interaction with bioelements is one of the critical mechanisms of Cd and Pb toxicity and malign transformation. This study aimed to investigate metal levels in blood, healthy, and tumor testis tissue and to reveal hormone, oxidative status, and bioelements levels in patients with TC. The study enrolled 52 patients with TC and 61 healthy volunteers. Toxic metals and bioelements levels were analyzed by atomic absorption spectrophotometry (AAS) while electrochemiluminescence immunoassay (ECLIA) and spectrophotometry methods were used for hormone and oxidative parameters evaluation. Significantly higher blood Cd levels were depicted in TC cohort. Furthermore, blood Cd elevation was associated with a 1.98 higher probability of TC developing. However, a metal concentration between healthy and tumor testis tissue did not differ significantly. Lower levels of estradiol and testosterone, established in a cohort of TC patients, followed the significant role of hormones in TC development. At the same time, ischemia-modified albumin (IMA) has been recognized as a parameter with very good accuracy as a potential diagnostic marker for TC. The study revealed different distribution patterns of copper (Cu) and zinc (Zn) in the three compartments of the patients, as well significant correlation between essential metals Cu/Zn and toxic metals Cd/Pb indicating metal-metal interactions as pivotal mechanisms of metals toxicity.

Considering the divergent biological behaviors of certain histological subtypes of urothelial carcinoma, it would be of great importance to examine the impact of variant histology and to predict its presence in patients with bladder cancer. A single-center cohort study included 459 patients who underwent radical cystectomy for urothelial carcinoma between 2017 and 2021. Patients were followed up with until July 2022. We compared clinical, laboratory, and histopathologic characteristics and the overall survival between patients with pure urothelial carcinoma and variant histologies. Our results showed that the patients with variant histology were older and preoperatively more frequently had hydronephrosis and higher values of leukocytes and neutrophils. Also, we found a significant association between variant histology and an advanced stage of tumor disease, the presence of lymphovascular invasion, positive surgical margins, and metastases in surgically resected lymph nodes. The number of neutrophils was identified as an independent preoperative predictor of the presence of variant histology after a radical cystectomy. The overall survival of the patients with variant histology was significantly lower compared to the patients with pure urothelial carcinoma. According to our results, the presence of variant histology represents a more aggressive form of the disease. Preoperative neutrophil counts may indicate the presence of variant histology of urothelial carcinoma in patients with bladder cancer.

BACKGROUND: Penile cancer (PC) is a highly aggressive disease, with a significant tendency for lymphatic spreading and subsequent development of distant metastases. The mutilating nature of PC surgical treatment has profound implications on the patient's body integrity and self-image, sexual life and intimacy, voiding and mental health. The aim of our study was to comprehensively evaluate PC patients' post-treatment quality of life (QoL), sexual activity, self-esteem, fatigue and fear of disease recurrence. (2) Methods: A cross-sectional study was conducted at the Clinic of Urology, University Clinical Centre of Serbia, and included 31 PC patients. Data were collected by means of a questionnaire. (3) Results: The average score on the Global health status scale was 67.2 out of 100 (ranging from 16.7 to 100), and the SD was 22.5. Hierarchical linear regression analysis showed that demographic characteristics, Hospital Anxiety and Depression scale (HADS) anxiety and depression scores, total Multidimensional Fatigue Inventory, Fear of cancer recurrence and Rosenberg scores and erectile function score explained a total of 78.2% of the variance in the global health status/QoL scale of PC patients. (4) Conclusions: Efforts should be made not only to increase the survival of PC patients after surgical treatment but also to enable the best possible level of QoL in the post-operative period.
RESUMO
At the time when mass COVID-19 vaccination began, providing appropriate vaccination advice to uro-oncology patients became a challenge. This was a single-center cross-sectional observational study aimed to investigate the rate of COVID-19 vaccination among uro-oncology patients receiving systemic therapy for metastatic renal cell carcinoma and metastatic castration-resistant prostate cancer. Furthermore, we aimed to assess patients' attitudes and identify factors influencing their decision to vaccinate against COVID-19. Data on patients' sociodemographic characteristics, vaccination status, and awareness and attitudes about COVID-19 vaccination were collected from questionnaires completed by the patients. A total of 173 patients were enrolled in this study, and 124 (71.7%) of them completed the COVID-19 vaccination. Significantly higher vaccination rates were found in male patients, and also in older patients, highly educated patients, and those who lived with one household member. Furthermore, we found significantly higher vaccination rates in patients who had consulted with doctors involved in their treatment, particularly with urologists. A significant association was observed between COVID-19 vaccination and doctor's advice, family member influence, and personal beliefs toward the vaccination. Our study showed multiple associations of patients' sociodemographic characteristics with vaccination rates. Furthermore, consultation with doctors who are particularly involved in oncology treatment and advice received from them were associated with significantly higher vaccination rates among uro-oncology patients.
RESUMO
We studied the potential role of exposure to various metal(oid)s (As, Cd, Cr, Hg, Ni, and Pb) in prostate cancer. Two cohorts were established: the Croatian cohort, consisting of 62 cases and 30 controls, and the Serbian cohort, consisting of 41 cases and 61 controls. Blood/serum samples were collected. Levels of investigated metal(oid)s, various parameters of oxidative stress, and prostate-specific antigen (PSA) were determined in collected samples. A comparison of the measured parameters between 103 prostate cancer patients and 91 control men from both Croatian and Serbian cohorts showed significantly higher blood Hg, SOD, and GPx levels and significantly lower serum SH levels in prostate cancer patients than in controls. Correlation analyses revealed the significant relationship between certain parameters of oxidative stress and the concentrations of the measured metal(loid)s, pointing to the possible role of metal(oid)-induced oxidative stress imbalance. Furthermore, a significant inverse relationship was found between the blood Pb and the serum PSA in prostate cancer patients, but when the model was adjusted for the impacts of remaining parameters, no significant association between the serum PSA and the measured parameters was found. The results of the overall study indicate a substantial contribution of the measured metal(loid)s to the imbalance of the oxidant/antioxidant system. Although somewhat conflicting, the results of the present study point to the possible role of investigated metal(oid)s in prostate cancer, especially for Hg, since the obtained relationship was observed for both cohorts, followed by the disturbances in oxidative stress status, which were found to be correlated with Hg levels. Nevertheless, further studies in larger cohorts are warranted to explain and confirm the obtained results.
RESUMO
Reproductive disorders and infertility have become more common recently among the general population. Toxic metals are known as endocrine disruptors and as they are widespread in nature they may be linked to reproductive problems. This study was conducted as a cross-sectional study and its aim was to examine the dose-response relationship between cadmium, arsenic, mercury, chromium and nickel and serum hormone levels of testosterone (women) and estradiol and progesterone (men) using the Benchmark dose approach (BMD). Blood samples were collected from 218 women and 217 men digested in a microwave, and the levels of the tested metals were determined by atomic absorption spectrophotometry (AAS) or inductively coupled plasma-mass spectrometry (ICP-MS). Dose-response analysis was performed in PROAST software (version 70.1). The model averaging method was used to calculate the Benchmark dose interval (BMDI). A dose-response relationship has been established between all metals and hormones. The narrowest BMDI was found for the As-testosterone and Hg-testosterone. Levels estimated to produce the extra risk of testosterone serum levels disturbances of 10% were lower than median levels measured in the general population. Moreover, this research suggests the possibility of use of the BMD approach in analyzing data pool generated from extensive human-biomonitoring studies.
RESUMO
BACKGROUND: High-dose-rate mono brachytherapy (HDR-MB) is employed in the treatment of prostate carcinoma (CaP). As an ideal plan of CaP brachytherapy cannot be created, it is necessary to identify a reliable tool to optimise the parameters of HDR-MB. This paper applies a multilayer artificial neural network (MANN) and a genetic algorithm (GA) to optimise brachytherapy parameters based on an individual dose-volumetric analysis. METHODS: Patients with localised CaP of various risks were treated with HDR-MB. Consecutive levels of the biochemical control parameter (prostate specific antigen (PSA) nadir) have been collected after completion of HDR-MB in the range 2-9 years. The Kaplan-Meier regression analysis of biochemical-free survival (BFS) was applied. The clinical risk of recurrent CaP (RCaP), the therapy dose (TD), TD coverage index (CI100%) and PSA nadir were modelled using the MANN and GA. RESULTS: In the low-risk group, BFS was achieved in 100% of treated patients, while in the group of patients with high risk, BFS was achieved in 95.8% of treated patients. The MANN-GA model optimises a TD of 47.3 Gy and CI100% of 1.14 as well as a TD of 50.4 Gy and CI100% of 1.6 for the low-risk group and high-risk group, respectively, of localised CaP. The optimised PSA nadir was 0.047 and 0.25 ng cm-3 for low-risk group and high-risk group, respectively. CONCLUSIONS: The developed MANN-GA model presents a method for optimising the treatment parameters in radiation therapy, which could be a valuable tool in planning of the HDR-MB.

Penile fracture is a rare urological emergency caused by blunt trauma to the erect penis and it may be accompanied by urethral injury. Complete urethral rupture is very uncommon and is usually managed by primary anastomosis. However, these patients are more likely to develop post-operative complications such as urethral strictures. Buccal mucosa graft is commonly used for substitution urethroplasty in management of urethral strictures, but its use has not been reported for immediate treatment in the setting of penile fracture. We report a patient with rupture of both corpora cavernosa, as well as the rupture of the urethra, after sexual intercourse. Buccal mucosa graft was used for surgical repair of urethral injury. At 36-month follow-up patient did not experience erectile or voiding problems. The application of this technique could possibly reduce the incidence of urethral strictures in these patients and further prospective studies with larger samples should be conducted.

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.

PURPOSE: To report our ongoing experience with dorsal buccal mucosa graft (BMG) urethroplasty for the primary repair of anterior urethral strictures in patients with lichen sclerosus (LS). PATIENTS AND METHODS: A total of 32 men with LS underwent BMG urethroplasty from January 2010 to September 2012. In 27 patients, stricture was limited to the penile urethra, while in five patients, both bulbar and penile urethra were involved. In these five patients, the entire anterior urethra was replaced with BMG. In nine (28.1%) younger patients (mean age 38.2 years, range 33-45), with adverse local conditions and significant scarring, two-stage repair was done. The paired t test was performed on preoperative and postoperative Qmax as well as on preoperative and postoperative post-void residual urine volume, and the Fisher exact test was used to assess success between treatment groups. The chi-squared test was used to compare categorical data. RESULTS: The overall success rate was 90.6%. Complications occurred in 9.4% of the patients (3 of 32) including hematoma in two patients and fistula in one patient. In this cohort of patients, mean preoperative Qmax was 6.2 ml per second (range 2.6-10.2) versus 18.2 (range 15.8-21.2) postoperatively (at 9 months), which was statistically significant (p < 0.002). Also, mean preoperative post-void residual urine volume was 110 ml (range 75-180) versus 19 ml (range 10-40) postoperatively at 9 months, which was statistically significant (p < 0.004). CONCLUSION: Buccal mucosa is the most reliable graft for repairing anterior urethral strictures in patients with LS. Minimal complications are observed, even in cases of long stenosis completely afflicting anterior urethra.

OBJECTIVE: To present the use of autologous buccal mucosa graft (BMG) in the treatment of recurrent vesicovaginal fistula (VVF). CASE REPORTS: In 2011, two women, aged 45 years and 56 years, were admitted due to recurrent VVF. Both women had previously undergone abdominal hysterectomies for benign conditions and, subsequently, vaginal VVF repair due to vaginal urine leakage. On admission, the younger woman had a round fistula, with a diameter of 1.5 cm, located on the left side, supratrigonally; the other woman had an ellipsoidal fistula measuring 2.5 cm × 1.5 cm, located medially and supratrigonally. Both women underwent suturing of the VVF with the interposition of BMG. After the last treatment, both women were cured. CONCLUSION: Treatment of recurrent VVF with the interposition of BMG is a good alternative to the use of other tissue grafts. Larger series are needed to confirm the advantages of this method.

INTRODUCTION: Triple renal pelvis is an extremely rare variation of the renal collecting system. To the authors' knowledge, bilateral triple renal pelvis has not yet been described in the literature. CASE REPORT: A 55-year-old man was hospitalized due to papillary bladder cancer, detected on ultrasonography. As incidental finding, intravenous urography revealed bilateral triple renal pelvis. Six weeks after transurethral resection of the bladder tumor (TURB) the patient was admitted again, for the second TURB. Computed to mography-urography confirmed the presence of bilateral triple renal pelvis. CONCLUSION: The unique case of bilateral triple renal pelvis was presented as an extremely rare variation of the renal collecting system.

BACKGROUND/AIM: Retroperitoneal fibrosis (RPF) repre sents a chronic pathological process characterized by fibro sis which entraps and compresses the ureters and the grea blood vessels in the retroperitoneal space. A specific form of RPF is idiopathic RPF, an uncommon collagen vasculaj disease of unclear etiology. The series of 15 patients whicl underwent open surgical repair due to idiopathic RPF is presented herein. METHODS: From 1989 to 2012, 11 male and 4 female patients underwent surgery due to primar RPF. The ureters were entrapped unilaterally (7 patients), or bilaterally (8 patients). Major symptoms included low bacl pain due to hydronephrosis (9 patients), uremia (4 patients) and urinary tract infection (2 patients). The diagnosis was based on intravenous urography (IVU), retrograde uretero pyelography and computed tomography (CT). RESULTS: Surgical procedures included intraperitoneal ureteral dis placement (8 patients) and ureteral wrapping with omental flap (6 patients). One patient underwent bilateral uretera stenotic segments resection and oblique ureterography, followed by wrapping with omental flap. Pathological examination confirmed primary RPF in all patients. The meat operative time was 3.5 h (range 2.5-4.5 h). The average in trahospital stay was 21 days (range 16-26 days). The meat follow up was 32 months (6-46 months). During the follow up, 12 patients had improvement on IVU. CONCLUSION: Early recognition of signs and symptoms of RPF is of the utmost importance for the outcome. Surgical procedures including ureteral wrapping with omental flap, or intraperi toneal ureteral displacement, usually represent definitive treatment.

BACKGROUND: Benign prostatic hyperplasia (BPH) and chronic prostatitis (CP) are disorders with high prevalence and have a great impact on overall morbidity in men. The patients that do not respond to medical therapy for lower urinary tract symptoms (LUTS) related to BPH are candidates for surgery. However, the number of men with BPH/LUTS seeking for non-surgical, or for less invasive treatment is growing. AIM: To present the basic information about minimally invasive treatment modalities for BPH and CP: intraprostatic injections, urethral lift procedures, modifications of transurethral microwave thermotherapy (TUMT), prostatic artery embolization etc. CONCLUSION: The majority of these techniques is still in experimental phase and not widely accepted. However, it is very likely that new, safe and minimally invasive techniques will appear in the near future.

Vesicovaginal fistulae (VVF)represents one of the most frequent complications of various gynecological and obstetric procedures. In presence of a gynecological malignant tumor, fistula could be the outcome of surgical complications, radiotherapy or consequence of the tumor process. Reparation of these fistulae is a very complex problem. Our aim was to analyze the results of surgical care VVF-s occurred in women with malignant gynecological disease which was treated surgically or with radiotherapy. Out of the 48 surgically treated patients with primary VVF, in 28 of them fistula occurred after hysterectomy, and in 20 patients after radiotherapy. In 15 patients (31.25%) transvaginal approach was applied, and in 33 patients (68.75%) abdominal approach was applied, with the interposition of a well vascularized lobe being used in 25 patients. All the VVFs that occurred after radiotherapy were repaired by using the abdominal approach. The efficiency of surgical treatment of VVFs after hysterectomy due to a malignant disease was 78.5%, and after radiotherapy 65%. In patients that have not been subjected to radiotherapy, depending on the characteristics of the fistula, transvaginal or abdominal approach is applicable in VVF reparation, while the abdominal approach remains a golden standard in post-radiation fistula treatment, despite the fact that it has not solved the problem after the first medical treatment in as far as 35% of patients.

The Mainz pouch II is a well tolerated form of continent urinary diversion in terms of morbidity, protection of the upper urinary tract and continence rate, even in patients aged > 65 years. Mainz pouch II was described by Fisch and Hohenfellner in 1991. They viewed the simplicity and reproducibility of the operation as one of its major advantages. A good continence rates between 93%-100% after this procedure has been shown in previous studies. The longer follow up will show whether these high rates of continence can be maintained with increasing age. The Mainz Pouch II serves as a satisfying continent urinary diversion for both sexes in selected patients in terms of quality of life. Evaluation of overall quality of life in patients with Mainz pouch II urinary derivation has given encouraging results. Compliance and cooperation of the patients, together with preoperative tests for anal competence, are mandatory to avoid complications. The Mainz group reported that the overall complication rate was low and comparable with other techniques of continent urinary diversion. During the past years modifications of the original technique have been described. These represent an increasing interest in the procedure. Today, the techniques of low-pressure and reservoirs have completely replaced classical ureterosigmoidostomy. In this review article the main focus is aimed at history, complications, continence and quality of life of patients with Mainz pouch II.
