History of Urology at the Sestre Milosrdnice University Hospital Center.

The history of Croatian urology clearly shows its affiliation to the medical and civilizational circle of the Western world. The Department of Urology at the Sestre milosrdnice University Hospital Center is the oldest urology institution in the Republic of Croatia. The Department was established in 1894, when the new Sestre milosrdnice Hospital was open in Vinogradska cesta in Zagreb. It was then that doctor Dragutin Masek founded the so-called III Department, which, in addition to treating urology patients, also treated patients with conditions of the ear, nose and throat, eye diseases and dermatologic conditions. Dragutin Masek had already realized that medicine would soon be divided into fields and had assigned younger doctors joining the III Department to specific fields. As a result, urology was given to Aleksandar Blaskovic, who founded the first independent department of urology in Croatia in 1926. In 1927, he was appointed Professor of urology at the Zagreb School of Medicine, where he established the first department of urology and was giving lectures and practicals. Under his leadership, the Department of Urology was given the status of a Clinic, a teach-ing department, the first of its kind in Croatia. Owing to all his activities in the field of urology, the history remembers him as the "father of modern Croatian urology". Over the course of the following years, department chairs had changed, but luckily for the patients, approach to work had not. Conscientiousness, trust, competence and charity. After all, charity is the idea that the hospital carries even in its name, after the Sisters of Charity who had founded it. In all the decades, the Department of Urology has been following global development paths, objectively legging behind top facilities in the world by only a few years. Overall professional and scientific urology activities culminated in 1998, when the Clinic became the Reference Center of the Ministry of Health of the Republic of Croatia for prostate cancer, and in 2011, when it became the European Board of Urology Certified Center. All that has been achieved could not have been done without wholehearted help and cooperation of the nurses, as well as every other department employee from the beginnings of urology until today. Despite its rich history, the Department does not rest on laurels. Today, it is a modern urology department together with its European role models.

20 Years of the Reference Center for Prostate Tumors of the Ministry Of Health at the Department of Urology in Sestre Milosrdnice University Hospital Center.

The Department of Urology at the Sestre milosrdnice University Hospital Center is the oldest urological institution in the Republic of Croatia and this part of Europe. Today, the Department is a modern tertiary healthcare institution, where the most complex methods of urological practice are performed using modern medical devices and highly sophisticated technology. In 2011, our urology specialist education program was certified by the European Board of Urology (EBU) as the only one of its kind in Croatia. The program was recertified in 2017. The Department runs a program for the early detection of prostate cancer and performs more than 240 radical prostatectomies annually, which is the highest number of such interventions in Croatia. The aim of this study is to present the work and the activities of the Reference Center for Prostate Tumors of the Ministry of Health at the Department of Urology in Sestre milosrdnice University Hospital Center over the last 20 years. The database of the Reference Center for Prostate Tumors of the Ministry of Health at the Department of Urology in Sestre milosrdnice University Hospital Center was reviewed. During the twenty-year period, approximately 15,000 prostate interventions were performed due to benign and malignant diseases. Of this, 7,374 transrectal ultrasound guided prostate biopsies, 2,632 radical prostatectomies with open retropubic access, 3,988 transurethral prostate resections and 1,097 open suprapubic adenomectomies were performed. With the achieved scientific and professional results in monitoring, studying and improving the prevention, diagnosis and therapy of prostate tumors, as well as with the professional conditions and personnel, the Department of Urology in Sestre milosrdnice University Hospital Center truly justifies the title of the Reference Center for Prostate Tumors of the Ministry of Health of the Republic of Croatia awarded to it in 1998.

Role of Multiparametric Magnetic Resonance Imaging in Prostate Cancer Assessment.

Multiparametric magnetic resonance is assuming an increasingly important role in the diagnosis, initial assessment and monitoring of patients with prostate cancer. This paper offers a more complex insight into the application of magnetic resonance imaging with prostate cancer, with a current literature overview. The focus is on the problem of initial prostate cancer evaluation which strongly affects further decision-making and therapeutic interventions. Clinical suggestions based on the current guidelines are also offered.

Cost-Benefit Analysis of the Introduction of Mp-Mri Guided Biopsies in Croatia.

The objective of this study was to determine differential expression of TFF1, TFF2 and TFF3 genes and proteins in breast tumor subtypes. In addition, we investigated the correlation between TFF genes within tumor subgroups, and TFF genes with clinical and pathologic characteristics of the tumor. Study group included 122 patients with surgically removed breast tumors. Samples were investigated using qRT-PCR and immunohistochemistry. TFF1 and TFF3 genes and proteins were expressed in breast tumors, while the levels of TFF2 gene and protein expression were very low or undetectable. TFF1 was significantly more expressed in benign tumors, while TFF3 was more expressed in malignant tumors. Gene and protein expression of both TFF1 and TFF3 was greater in lymph node-negative tumors, hormone positive tumors, tumors with moderate levels of Ki67 expression, and in grade II tumors. A strong positive correlation was found between TFF1 and TFF3 genes, and the expression of both negatively correlated with Ki67 and the level of tumor histologic differentiation. Our results suggest that TFF1 and TFF3, but not TFF2, may have a role in breast tumor pathogenesis and could be used in the assessment of tumor differentiation and malignancy.

Transobturator Advance® Sling Suspension for the Treatment of Postprostatectomy Stress Urinary Incontinence.

Stress urinary incontinence (SUI) continues to present a major complication after radical prostatectomy. Suburethral slings represent one of the less invasive options for postprostatectomy SUI, and a more recent addition is a transobturator sling, the AdVance®. We report our results with the AdVance® sling for the management of postoperative SUI. The evaluation was conducted on 47 patients with AdVance® implant for SUI in our institution (November 2010 - June 2017). Measurements included age, etiology of SUI, duration of SUI, follow-up and pad use per day (PPD) pre- and postoperatively. Patients were classified as cured if they used no pads or 1 PPD for security reasons, or as improved if 1-2 PPDs were used and if there was a 50% reduction in pad use per day postoperatively. In our series we observed a reduction of mean PPD of 5.1 (2-8) to 1.7 (0-4) postoperatively. After follow-up and according to our criteria, the cure rate was 51.1% (24/47) and the improvement rate 27.5% (13/47). The overall success rate was 78.6% (37/47). No improvement was observed in 21.4% (10/47) of patients. Failure rates after sling placement for patients with addi-tional treatments following prostatectomy were much higher (60% (3/10) for radiation therapy and 66.7% (4/10) for urethral stricture disease). Our results show favourable cure and improvement rates and are comparable to results from larger series. The most appropriate candidates for the AdVance® sling are patients with mild to moderate postprostatectomy SUI. The results may be even better in patients without additional treatment following prostatectomy, such as radiation therapy or surgery for stricture disease.

The evolution of partial nephrectomy for kidney tumors--are we abandoning the basic principles of Robson's radical nephrectomy?

Fifty years ago, Robson introduced radical nephrectomy (RN) setting the gold standard for treating kidney tumors. Experience has shown that partial nephrectomy (PN) can be equally effective with the advantages of preserving kidney function and avoiding unnecessary nephrectomies for benign tumors. The purpose of this report is to demonstrate the evolution of clinical presentation and choice of treatment for patients with kidney tumors at our department, emphasizing changes in the PN utilization trends. Clinical data were abstracted for the years 2002, 2007 and 2012. We assessed annual trends for changes in the choice of operative treatment related to tumor size, pathologic stage and diagnosis. During the study, there was an increase in the share of T1 tumors, from 46.6% in 2002 to 69.8% in 2012. The rate of PN increased more than ten-fold, from 2.7% in 2002 to 31.7% in 2012. The annual rates of PN for T1 tumors increased even more, from 6.6% in 2002 to 46.7% in 2012. Opposite to RN group, there was an increase in the mean tumor size in PN group (from 1.8 cm in 2002 to 3.9 cm in 2012). The rate of RN for benign tumors was reduced impressively from 85.7% in 2002 to 23.1% in 2012. Our data argue strongly that PN should be expanded and not restricted. Robson's principles have been partially deserted over the last decade; however, proving that PN is superior to RN still remains to be elucidated.

The methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and cancer risk: the Croatian case-control study.

OBJECTIVES: Methylation abnormalities appear to be important for the pathogenesis of many cancer types. Since methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the methylation process catalyzing reduction of 5,10-methylenetetrahydrofolate to 5-methyl-tetrahydrofolate, C677T polymorphism, which decreases enzyme activity, may be associated with cancer susceptibility. The aim of this work was to investigate the distribution of MTHFR C677T polymorphism between various types of cancer and cancer-free controls and to assess if there is a difference in frequency. MATERIALS AND METHODS: 269 Cancer cases (95 prostate cancer, PC; 81 head and neck, HN; and 93 breast cancers, BC) and 102 healthy controls, free of cancer, were genotyped for C677T MTHFR polymorphism using the PCR-RFLP method. RESULTS: There was no overall difference in C677T genotype distribution between total cancer cohort and controls (p=0.064). However, a significant difference and protective OR was found for the C/T genotype (OR=0.574, 95% CI=0.352-0.935). In a comparison of different cancer types and respective controls, genotype frequencies were significantly different between head and neck carcinoma and controls (p=0.004), again with protective role of C/T genotype (OR=0.356, 95% CI=0.189-0.671). Moderate overrepresentation of C/T was found in respective male controls when compared with prostate cancer patients (p value was 0.074 for C/T vs. C/C comparison). The OR for heterozygous C/T genotype in prostate cancer group was 0.404, pointing to its putative protective role. Genotype and allelic frequencies did not differ significantly between 93 breast cancer patients and their 65 age-matched female controls. CONCLUSION: Our data indicate that the C677T MTHFR polymorphism does not significantly contribute to the inherited genetic susceptibility to breast and prostate cancer, while we show some evidence for possible genetic contribution of this polymorphism to the development of head and neck carcinoma.
