[Could robotic surgery really be a revolutionary change in the treatment of kidney cancer in Hungary?] / Valóban forradalmi változást jelenthet a robotsebészet a veserákok kezelésében Magyarországon?

Robotic-assisted partial nephrectomy (RAPN) was first described in 2004 and, since its introduction in clinical practice, has progressively gained increasing popularity. Over the years, the indications have also expanded, enabling robot-assisted surgical removal of complex kidney tumors. Important considerations for clinicians when choosing a minimally invasive technique are complete resection of the tumor, maximum protection of kidney function, and avoidance of complications. The first Da Vinci robotic surgery system was installed in Hungary at the Jahn Ferenc Dél- Pest Hospital and the National Institute of Oncology. The first robotic surgery took place at the National Institute of Oncology, and then at the Jahn Ferenc Dél-Pest hospital. In addition to open surgeries, only the laparoscopic procedure was available to perform kidney tumor surgeries in Hungary. The short one-year robotic surgery experience in our country supports the results of the international literature. Due to the introduction of robotics, a higher level of precision and freedom of movement creates new opportunities compared to open or laparoscopic kidney tumor surgeries.

The Correlation Between Platelet Count and Survival in Prostate Cancer.

Purpose: A number of studies have confirmed that elevated platelet count accompanying various solid tumours is associated with worse survival. However, only meagre data are available on the relationship between thrombocytosis and survival in prostate cancer. Methods: We conducted a retrospective analysis on clinical-pathological data accumulated from 316 patients during on average 51 months of follow-up after laparoscopic prostatectomy performed for prostate cancer. We analyzed the relationship between platelet count, risk factors, prostate-specific antigen (PSA) and cancer stage with use the Tumor, Node, Metastase system (TNM), as well as surgical margin, and prognosis. Results: Thrombocytosis occurred in only one out of the 316 patients. The multivariate Cox proportional hazard model showed that preoperative PSA, risk group, preoperative haemoglobin level, and surgical margin status were significant, independent predictors of biochemical progression-free survival. By contrast, age at diagnosis and thrombocytosis had no such predictive value. Conclusion: We could not demonstrate an association between elevated platelet count and worse survival in our study population of patients with prostate cancer.

[Modern surgical treatment of urothelial tumors]. / Uroteliális daganatok modern sebészi kezelése.

Urothelial cell tumors are the most common malignant urinary tract lesions, affecting the bladder in the majority of cases, however, 5% of the tumors occur in the upper urinary tract (urethra, renal pelvis). About 2,000 new diseases occur in Hungary every year and due to this tumor, almost 1,000 deaths occur in every year. The purpose of this paper is to summarize the results of radical surgery indicated in patients with non-invasive and muscle-invasive urothelial cancer, as well as its international recommendations. Based on the AUA and EAU guidelines, the latest and standard treatment options are described. Transurethral resection (TUR) is still a gold standard in the initial diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). The indication for radical cystectomy in addition to muscle invasive tumors (T2-T4a, N0-Nx, M0) is BCG resistant in T1G3 (evidence level: 3, recommendation level: B). Risk stratification is of paramount importance for the future treatment and follow-up of patients with bladder urothelial cell tumors. Although the proportions of changes in surgical care lag behind the novelties of urooncological treatments, advances in surgical technique, urinary tract reconstruction, and multimodal therapy may continue to improve the prognosis and quality of life of patients with bladder urothelial cell tumors.

Condition-specific surveillance in health care-associated urinary tract infections as a strategy to improve empirical antibiotic treatment: an epidemiological modelling study.

BACKGROUND: Health care-associated urinary tract infection (HAUTI) consists of unique conditions (cystitis, pyelonephritis and urosepsis). These conditions could have different pathogen diversity and antibiotic resistance impacting on the empirical antibiotic choices. The aim of this study is to compare the estimated chances of coverage of empirical antibiotics between conditions (cystitis, pyelonephritis and urosepsis) in urology departments from Europe. METHODS: A mathematical modelling based on antibiotic susceptibility data from a point prevalence study was carried. Data were obtained for HAUTI patients from multiple urology departments in Europe from 2006 to 2017. The primary outcome of the study is the Bayesian weighted incidence syndromic antibiogram (WISCA) and Bayesian factor. Bayesian WISCA is the estimated chance of an antibiotic to cover the causative pathogens when used for first-line empirical treatment. Bayesian factor is used to compare if HAUTI conditions did or did not impact on empirical antibiotic choices. RESULTS: Bayesian WISCA of antibiotics in European urology departments from 2006 to 2017 ranged between 0.07 (cystitis, 2006, Amoxicillin) to 0.89 (pyelonephritis, 2009, Imipenem). Bayesian WISCA estimates were lowest in urosepsis. Clinical infective conditions had an impact on the Bayesian WISCA estimates (Bayesian factor > 3 in 81% of studied antibiotics). The main limitation of the study is the lack of local data. CONCLUSIONS: Our estimates illustrate that antibiotic choices can be different between HAUTI conditions. Findings can improve empirical antibiotic selection towards a personalized approach but should be validated in local surveillance studies.

Evaluation of the draft guidelines proposed by EMA and FDA for the clinical diagnosis of acute uncomplicated cystitis in women.

PURPOSE: To reassess the diagnostic values of the "draft" guidelines for the clinical diagnosis of acute uncomplicated cystitis (AC), recently proposed by US Food and Drug Administration (FDA) and European Medicines Agency (EMA). METHODS: The data of 517 female respondents (patients with acute cystitis and controls) derived from the e-USQOLAT database were analyzed and used for the validation of proposed "draft" guidelines of FDA and EMA, compared to the Acute Cystitis Symptom Score (ACSS) questionnaire. The diagnostic values of the proposals concerning signs, symptoms and their severity were assessed and compared. RESULTS: The six "typical" symptoms of the ACSS were strongly associated with the diagnosis of AC. The number of positive "typical" symptoms differed significantly between patients and controls: median 5 (IQR 4-6) vs 1 (IQR 0-3) respectively. Scored severity of "typical" symptoms also differed significantly between groups of patients and controls: median (IQR) 10 (7-13) vs 1 (0-4), respectively. The best balance between sensitivity and specificity is shown by the ACSS cut-off value of 6 scores and more of the "Typical" domain, followed by an approach proposed by FDA and EMA, justifying ACSS to be used as a diagnostic criterion for the clinical diagnosis of AC. CONCLUSIONS: Not only the presence but also the severity of the symptoms is important for an accurate diagnosis of AC. The ACSS, even without urinalysis is at least as favourable as the draft diagnostic proposals by FDA and EMA. The ACSS can be recommended for epidemiological and interventional studies, and allows women to establish self-diagnosis of AC, making the ACSS also cost-effective for healthcare.

Antibiotic resistance, hospitalizations, and mortality related to prostate biopsy: first report from the Norwegian Patient Registry.

BACKGROUND: A 68-year-old man died of cerebral arterial embolism 6 days after transrectal prostate biopsy with a single p.o. dose of trimethoprim sulfamethoxazole (TMP-SMX) as prophylaxis. The case precipitated analysis of local antibiotic resistance and complication rates. MATERIALS AND METHODS: Data on E. coli resistance from Oslo University Hospital and national data on hospitalizations and mortality after biopsy were retrieved from local microbiology files and the Norwegian Patient Registry (NPR) 2011-2017. RESULTS: Urine E. coli resistance against TMP-SMX increased from 35% in 2013 to more than 60% in 2015. For ciprofloxacin, the resistance increased from 15% in 2013 to about 45% in 2016. The highest annual E. coli resistance in blood cultures for TMP-SMX and ciprofloxacin was 37% and 28%, respectively. 10% of patients were hospitalized with a diagnosis of infection within the first 60 days after biopsy and there was a relative increase in mortality rate of 261% within the first 30 days. Due to the severity of the figures, the story and the NPR data were published in Norway's leading newspaper and were succeeded by a series of chronicles and commentaries. CONCLUSIONS: Several critical points of the biopsy procedure were not performed according to current standards. We believe that the patient might have died of septic embolism after biopsy. As a result of the findings and the debate, local practice was changed from transrectal to transperineal prostate biopsies.

Transurethral Resection of the Prostate: are We Following the Guidelines? - Outcomes from the Global Prevalence of Infections in Urology (GPIU) Study.

Transurethral resection of the prostate (TURP) is one of the most common urological procedures. With the increasing rate of multiresistant infections including urosepsis, it is essential for all surgeons to adhere to the relevant international guidelines to prevent infectious complications. The aim of this prospective, multinational, multicentre study was to evaluate compliance with recommended infection control measures regarding TURP procedures. The study was performed as a side questionnaire to the annual Global Prevalence Study of Infections in Urology (GPIU) between 2006 and 2009. Patients that had undergone TURP were eligible. Baseline data about hospitals and patients were collected. The questionnaire contained questions regarding preoperative microbiological investigations, catheter care and performance of perioperative antibiotic prophylaxis. A total of 825 men were included from 138 participating centres from Africa, Asia, Europe and South America. Only 50.1% of the patients received perioperative antibiotic prophylaxis with a median duration of 3 days (interquartile range [IQR] = 1-7 days). Preoperative urine culture was taken in 59.2%. The catheter was replaced in 1 week prior to the surgery only in 38.3% of cases. Compliance with the recommended infection control measures regarding TURP were only moderate, despite high grade recommendations in relevant international Guidelines. Stronger guideline adherence is necessary to improve patient care decrease antibiotic consumption in line with antibiotic stewardship in surgical practices.

Cefiderocol versus imipenem-cilastatin for the treatment of complicated urinary tract infections caused by Gram-negative uropathogens: a phase 2, randomised, double-blind, non-inferiority trial.

BACKGROUND: Carbapenem-resistant Gram-negative bacteria represent the highest priority for addressing global antibiotic resistance. Cefiderocol (S-649266), a new siderophore cephalosporin, has broad activity against Enterobacteriaceae and non-fermenting bacteria, such as Pseudomonas aeruginosa and Acinetobacter baumannii, including carbapenem-resistant strains. We assessed the efficacy and safety of cefiderocol versus imipenem-cilastatin for the treatment of complicated urinary tract infection in patients at risk of multidrug-resistant Gram-negative infections. METHODS: We did a phase 2, multicentre, double-blind, parallel-group non-inferiority trial at 67 hospitals in 15 countries. Adults (≥18 years) admitted to hospital with a clinical diagnosis of complicated urinary tract infection with or without pyelonephritis or those with acute uncomplicated pyelonephritis were randomly assigned (2:1) by an interactive web or voice response system to receive 1 h intravenous infusions of cefiderocol (2 g) or imipenem-cilastatin (1 g each) three times daily, every 8 h for 7-14 days. Patients were excluded if they had a baseline urine culture with more than two uropathogens, a fungal urinary tract infection, or pathogens known to be carbapenem resistant. The primary endpoint was the composite of clinical and microbiological outcomes at test of cure (ie, 7 days after treatment cessation), which was used to establish non-inferiority (15% and 20% margins) of cefiderocol versus imipenem-cilastatin. The primary efficacy analysis was done on a modified intention-to-treat population, which included all randomly assigned individuals who received at least one dose of study drug and had a qualifying Gram-negative uropathogen (≥1 × 105 colony-forming units [CFU]/mL). Safety was assessed in all randomly assigned individuals who received at least one dose of study drug, according to the treatment they received. This study is registered with ClinicalTrials.gov, number NCT02321800. FINDINGS: Between Feb 5, 2015, and Aug 16, 2016, 452 patients were randomly assigned to cefiderocol (n=303) or imipenem-cilastatin (n=149), of whom 448 patients (n=300 in the cefiderocol group; n=148 in the imipenem-cilastatin group) received treatment. 371 patients (n=252 patients in the cefiderocol group; n=119 patients in the imipenem-cilastatin group) had qualifying Gram-negative uropathogen (≥1 × 105 CFU/mL) and were included in the primary efficacy analysis. At test of cure, the primary efficacy endpoint was achieved by 183 (73%) of 252 patients in the cefiderocol group and 65 (55%) of 119 patients in the imipenem-cilastatin group, with an adjusted treatment difference of 18·58% (95% CI 8·23-28·92; p=0·0004), establishing the non-inferiority of cefiderocol. Cefiderocol was well tolerated. Adverse events occurred in 122 (41%) of 300 patients in the cefiderocol group and 76 (51%) of 148 patients in the imipenem-cilastatin group, with gastrointestinal disorders (ie, diarrhoea, constipation, nausea, vomiting, and abdominal pain) the most common adverse events for both treatment groups (35 [12%] patients in the cefiderocol group and 27 [18%] patients in the imipenem-cilastatin group). INTERPRETATION: Intravenous infusion of cefiderocol (2 g) three times daily was non-inferior compared with imipenem-cilastatin (1 g each) for the treatment of complicated urinary tract infection in people with multidrug-resistant Gram-negative infections. The results of this study will provide the basis for submission of a New Drug Application to the US Food and Drug Administration. Clinical trials of hospital-acquired pneumonia and carbapenem-resistant infections are ongoing. FUNDING: Shionogi & Co Ltd, Shionogi Inc.

The role of the Acute Cystitis Symptom Score questionnaire for research and antimicrobial stewardship. Validation of the Hungarian version.

INTRODUCTION: The Acute Cystitis Symptom Score (ACSS) is a new self-reporting tool to evaluate the symptoms of uncomplicated acute cystitis (AC) in women. The linguistic and clinical validation process of the Hungarian version used in this study may serve as a guide for the validation of the ACSS in other languages. MATERIAL AND METHODS: In this prospective cohort study, women with AC (Patients) and those without (Controls) filled in the Hungarian ACSS version, during their visits to physician's office. Statistical analysis included ordinary descriptive values, calculation of reliability, validity, discriminative ability, responsiveness (sensitivity, specificity) and comparative analysis. RESULTS: Thirty-one patients were recruited for validation along with 37 controls. Statistical analyses resulted in excellent values of internal consistency, discriminative ability and validity for diagnosis of AC. At the cut-off at a score of 6 in the 'typical' domain, positive and negative predictive values were 97% and 92%, sensitivity and specificity were 90% and 97%, respectively. CONCLUSIONS: The ACSS has demonstrated benefits for diagnosis and patient-reported outcome assessment. It is objective, fast, and cost-effective, and may help to easily confirm the accurate diagnosis of AC. Therefore, it may be especially important for clinical and epidemiological studies on AC in women.

[Image-guided radiotherapy for muscle invasive bladder cancer with intravesical lipiodol injection. A new option for bladder sparing treatment]. / Izominvazív hólyagrák képvezérelt sugárkezelése intravesicalisan befecskendezett lipiodolos jelöléssel. A hólyagmegtartó kezelés új lehetosége.

INTRODUCTION AND AIM: To implement lipiodol as a fiducial marker of the tumor bed for image-guided radiotherapy with simultaneous integrated boost technique as part of radiochemotherapy for muscle invasive bladder tumors. METHOD: Since April 2016, radiochemotherapy was performed in 3 male patients with muscle invasive, transitional cell bladder carcinoma. Prior to radiochemotherapy, tumor bed resection was performed for each patient, at the same time 10 ml of lipiodol solution was injected submucosally into the resection site, thus marking the tumor bed for escalated dose irradiation. During radiochemotherapy 51 Gy (1.7 Gy/die) to the pelvis, 57 Gy (1.9 Gy/die) to the whole bladder, and 63 Gy (2.1 Gy/die) to the lipiodol-labeled tumor bed was delivered with simultaneous integrated boost technique. The accuracy of the irradiation was controlled by daily kilovoltage CT. Early radiogenic urogenital and gastrointestinal side effects were recorded according to Radiation Therapy Oncology Group side-effects grading recommendation. RESULTS: Substantial perioperative side effect or toxicity were not observed during and after the injection of lipiodol. The prescribed dose was successfully delivered in all patients. Radiotherapy duration was 6 weeks. The lipiodol-labeled tumor bed was clearly visible on daily kilovoltage cone beam CT. In one patient grade II cystitis and proctitis was observed, another patient experienced only grade I cystitis. These complaints improved with symptomatic medication. In the third patient no significant side effect occurred. CONCLUSIONS: The injection of lipiodol into the bladder wall is a safe technique, without any perioperative toxicity or complication. The tumor bed demarcated by lipiodol was visible both on treatment planning and kilovoltage CTs. The total treatment time was shortened by 4 days. The treatment was well tolerated, early side effects were moderate, or slight. Orv Hetil. 2017; 158(51): 2041-2047.

Spectrum and antibiotic resistance of uropathogens between 2004 and 2015 in a tertiary care hospital in Hungary.

PURPOSE: Surveillance of the bacterial spectrum and antibiotic-resistance patterns of locally occurring uropathogens is essential to serve as a basis for empirical treatment of urinary tract infections (UTIs), as antibiotic-resistance rates may vary geographically with significant differences between countries and regions, and with time. METHODOLOGY: We retrospectively analysed all urine samples taken in the department of urology in a tertiary care hospital in Hungary from January 2004 to December 2015.Results/Key findings. The five most commonly occurring bacteria were Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa and Proteus mirabilis. Resistance of Escherichia coli to ciprofloxacin increased significantly from 19 to 25 %. Although the resistance of Escherichia coli against cephalosporins showed an increasing trend, it still remained generally low. However, resistance rates of K. pneumoniae to cephalosporins were very high, reaching 60 %, due to the high rate of extended-spectrum-ß-lactamase-positive Klebsiella strains. We observed a significant increase in the rate of carbapenem-resistant Pseudomonas aeruginosa. CONCLUSION: Fluoroquinolones cannot be recommended for empirical treatment in our region. Cephalosporins can be a good empirical choice for treating Gram-negative UTIs, but should be avoided when multi-drug resistant (MDR) bacteria are suspected. Increases in the rate of carbapenem-resistant Pseudomonas aeruginosa, and in the general rate of MDR bacteria, are both a very alarming trend. We recommend practising prudent antibiotic policy, preferably using antibiotics with the narrowest possible spectrum.

Phase 2 Study of 99mTc-Trofolastat SPECT/CT to Identify and Localize Prostate Cancer in Intermediate- and High-Risk Patients Undergoing Radical Prostatectomy and Extended Pelvic LN Dissection.

99mTc-trofolastat (99mTc-MIP-1404), a small-molecule inhibitor of prostate-specific membrane antigen, shows high potential to detect prostate cancer (PCa) noninvasively using SPECT. We therefore wanted to assess the performance of 99mTc-trofolastat SPECT/CT in a phase 2 multicenter, multireader prospective study in patients with intermediate- and high-grade PCa, before radical prostatectomy and extended pelvic lymph node (LN) dissection, with histopathology as the gold standard. Methods: PCa patients (n = 105) with an increased risk of LN involvement (LNI) underwent pelvic 99mTc-trofolastat SPECT/CT before radical prostatectomy with extended pelvic LN dissection. The sensitivity of 99mTc-trofolastat for detection of PCa on a patient and lobe basis, using visual and semiquantitative (tumor-to-background ratio [TBR]) scores, and of LNI was evaluated as well as the correlation of uptake within the gland to Gleason scores (GS) and assessment of the predictive potential of 99mTc-trofolastat uptake for LNI. Results: PCa was detected in 98 patients (94%) with acceptable variability between readers. There was a significantly higher visual score and TBR in positive lobes compared with tumor-negative lobes. Receiver-operating characteristic analysis showed that visual scores more accurately discriminated lobes with GS ≤ 3 + 3 from ≥ 3 + 4, whereas TBRs discriminated high-grade disease from normal lobes better. Visual scores and TBRs correlated significantly with GS. 99mTc-trofolastat SPECT/CT detected LNI with a sensitivity of 50% and specificity of 87%, and TBR values significantly predicted LNI with a sensitivity of 90%. Conclusion:99mTc-trofolastat SPECT/CT detects PCa with high sensitivity in patients with intermediate- and high-risk PCa compared with histology. It has the potential to be used as a surrogate marker for GS and predict LNI.

Spectrum and antibiotic resistance of catheter-associated urinary tract infections.

Catheter associated urinary tract infections (CAUTIs) are amongst the most common nosocomial infections and are also considered among the most common complications associated with indwelling urinary catheters. Most catheter associated infections are derived from the patient's own perineal flora, however the presence of a catheter increases the chance of being colonised by cross transmission of nosocomial bacteria as well. Most episodes of short-term catheter-associated bacteriuria are asymptomatic and are caused by single organisms, while long-term catheterisation promotes multibacterial infections and colonization. With prolonged duration of catheterization bacteriuria is considered universal because of the formation of biofilms on the surface of the catheter. Chronic indwelling catheters are an important reservoir of different multiresistant gram-negative organisms, therefore they are frequently isolated from CAUTIs. Treatment of catheter associated asymptomatic bacteriuria is not recommended because it will only promote the emergence of resistant organisms without effectively clearing the urine of catheterised patients.

The Global Prevalence of Infections in Urology Study: A Long-Term, Worldwide Surveillance Study on Urological Infections.

The Global Prevalence of Infections in Urology (GPIU) study is a worldwide-performed point prevalence study intended to create surveillance data on antibiotic resistance, type of urogenital infections, risk factors and data on antibiotic consumption, specifically in patients at urological departments with healthcare-associated urogenital infections (HAUTI). Investigators registered data through a web-based application (http://gpiu.esiu.org/). Data collection includes the practice and characteristics of the hospital and urology ward. On a certain day in November, each year, all urological patients present in the urological department at 8:00 a.m. are screened for HAUTI encompassing their full hospital course from admission to discharge. Apart from the GPIU main study, several side studies are taking place, dealing with transurethral resection of the prostate, prostate biopsy, as well as urosepsis. The GPIU study has been annually performed since 2003. Eight-hundred fifty-six urology units from 70 countries have participated so far, including 27,542 patients. A proxy for antibiotic consumption is reflected by the application rates used for antibiotic prophylaxis for urological interventions. Resistance rates of most uropathogens against antibiotics were high, especially with a note of multidrug resistance. The severity of HAUTI is also increasing, 25% being urosepsis in recent years.

The Global Prevalence of Infections in Urology (GPUI) Study: A Worldwide Surveillance Study in Urology Patients.

The GPIU study is currently the only study registering health care-associated urogenital tract infections, especially in urology patients, in an ongoing surveillance protocol that can help to deliver data on adequate empirical antibiotic therapy in hospitalised urology patients according to guideline recommendations. The annual GPIU study will continue to be performed in November of each year under the URL http://gpiu.esiu.org/.

Antimicrobial resistance in urosepsis: outcomes from the multinational, multicenter global prevalence of infections in urology (GPIU) study 2003-2013.

OBJECTIVE: Primary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in patients with urosepsis. POPULATION AND METHODS: A point prevalence study carried out in 70 countries (2003-2013). Population studied included; 408 individuals with microbiologically proven urosepsis, 1606 individuals with microbiological proof of HAUTI and 27,542 individuals hospitalised in urology wards. Main outcomes are pathogens and resistance identified in HAUTIs and urosepsis including its clinical severity. A statistical model that included demographic factors (study year, geographical location, hospital setting) was used for analysis. RESULTS: Amongst urology practices, the prevalence of microbiologically proven HAUTI and urosepsis was 5.8 and 1.5 %, respectively. Frequent pathogens in urosepsis were E. coli (43 %), Enterococcus spp. (11 %), P. aeruginosa (10 %) and Klebsiella spp. (10 %). Resistance to commonly prescribed antibiotics was high and rates ranged from 8 % (imipenem) to 62 % (aminopenicillin/ß lactamase inhibitors); 45 % of Enterobacteriaceae and 21 % of P. aeruginosa were multidrug-resistant. Resistance rates in urosepsis were higher than in other clinical diagnosis of HAUTI (Likelihood ratio <0.05). CONCLUSIONS: It is not appropriate to use the pathogen spectrum and resistance rates of other HAUTIs as representative of urosepsis to decide on empirical treatment of urosepsis. Resistance rates in urosepsis are high, and precautions should be made to avoid further increase.

[Our experience with totally extraperitoneal technique of laparoscopic inguinal hernia repairs modified by Stolzenburg]. / Stolzenburg szerint módosított teljes extraperitonealis technikával végzett laparoscopos lágyéksérvmutéteinkrol.

INTRODUCTION: Two current types of laparoscopic inguinal hernia repair are known: the TransAbdominal PrePeritoneal (TAPP) and the Totally ExtraPeritoneal (TEP) method. The mesh is placed in the preperitoneal space (sublay). Usually during TAPP method we fix the mesh with tacks or staples. In case of TEP fixation it is not necessary because the intraabdominal pressure keeps the implant in position. There is no significant difference between the two methods in terms of recurrence. The advantage of TEP is that the abdominal cavity remains intact, hence reduces the risk of intraabdominal injuries and adhesions. It is unnecessary to use special stapler or tacker. MATERIALS AND METHODS: Our team performed 50 TEP procedures in male patients with uni- or bilateral inguinal hernias in the period 2011-2013. We prepared the mesh in a special way according to Stolzenburg and placed it to the subfunicular area. We did not apply additional fixation (tacks, stitches) and drainage. Mean hospital stay was 1 day. We allowed complete physical activity 10-12 days after surgery. RESULTS: No recurrence was observed during the 2 years of follow-up. The mean operating time was 70 minutes. We performed conversion in 3 cases (Lichtenstein 2, TAPP 1). In one case there was an injury of the inferior epigastric artery. In two cases we have detected neuralgia in the postoperative period. CONCLUSIONS: After the learning curve the TEP method can be used safely with good functional results. The technique of mesh positioning reduces the risk of complications and provides cost-effectiveness.

Healthcare-associated urinary tract infections in hospitalized urological patients--a global perspective: results from the GPIU studies 2003-2010.

INTRODUCTION: European Section for Infections in Urology has been conducting an annual prevalence survey investigating various aspects of healthcare-associated urinary tract infections (HAUTI) since 2003. MATERIAL AND METHODS: The data on various clinical categories of HAUTI, the contamination status of HAUTI patients who underwent any urological intervention with regard to microorganisms isolated, resistance status and antibiotics used to treat HAUTI will be presented. RESULTS: Of a total of 19,756 patients screened, 1,866 patients had HAUTI (9.4 %); 1,313 males (70.4 %) and 553 (29.6 %) females. Mean age was 59.9 ± 18.2. Asymptomatic bacteriuria (ASB) and cystitis were the most frequent clinical diagnoses representing 27.0 and 26 % of all HAUTI, respectively. Echerichia coli was found to be the most frequent uropathogen (544 of 1,371 isolates) (39.7 %). Fluoroquinolones were preferred in 26.6 % of cases followed by cephalosporins (23.3 %), aminoglycosides (14.1 %) and penicillins (13.8 %). High global resistance rates to ciprofloxacin (>50 %), cephalosporins (35-50 %) and penicillins (50 %) were found in the GPIU studies 2003-2010. DISCUSSION: We showed that around 10 % of hospitalized urological patients are at risk to develop HAUTI often caused by multiresistant uropathogens. Increased antibiotic use often with broad-spectrum antimicrobials will inevitably be followed by increasing bacterial resistance. To interrupt such a vicious cycle, our results suggest (1) there is still room for improvement in surgical prophylaxis in terms of limiting exposure to antibiotics and (2) far too many patients with ASB are being treated which shows that the new proposal of classification should be adopted where ABS is regarded as colonization and not as an infection to be treated.

An update on prevention and treatment of catheter-associated urinary tract infections.

PURPOSE OF REVIEW: Catheter-related urinary tract infections (UTIs) are among the most important nosocomial infections. This review summarizes the latest advances in the field of catheter care and the management of catheter-associated UTIs. RECENT FINDINGS: The most efficient methods to prevent catheter-associated UTIs are to avoid unnecessary catheterizations and to remove catheters as soon as possible. The use of different reminder systems and implementation of infection control programs can effectively decrease catheter-associated UTIs, although their introduction can be challenging. There is still no evidence to support the routine use of antimicrobial-impregnated catheters, but the use of hydrophilic-coated catheters for clean intermittent catheterization can effectively reduce infections. Preliminary results with chlorhexidine-coated catheters are promising. In cases of serious catheter-associated UTI in patients with a history of previous antibiotic therapy or healthcare-associated bacteraemia, empirical antibiotic treatment should be initiated with activity against multiresistant uropathogens. Suprapubic catheterization is not superior to urethral catheters in terms of reducing the rate of catheter-related bacteriuria. SUMMARY: A technology to prevent catheter-associated UTIs is still not available; however, there are promising results with new approaches such as the use of reminder systems and infection control programs, which can effectively decrease the rate of catheter-associated UTIs. There is evidence supporting the use of hydrophilic coated catheters for clean intermittent catheterization, but an optimal catheter material or coating still has to be developed. Evidence-based catheter management is crucial for every patient in need of a catheter.

Resistance patterns of nosocomial urinary tract infections in urology departments: 8-year results of the global prevalence of infections in urology study.

OBJECTIVE: To present the worldwide antibiotic resistance rates of uropathogens reported in nosocomial urinary tract infections (NAUTI) during the period of 2003-2010. MATERIALS AND METHODS: Data from the Global Prevalence Study of Infections in Urology from the period of 2003-2010 were analyzed to evaluate the resistance rates of pathogens causing NAUTI. The web-based application was used to record data of investigators from urology departments participating in the study every year during the days allocated in November. Each center was allowed to enter data on a single day of the study. The point prevalence data was used to find differences among geographic regions and years by utilizing multiple logistic regression analysis. RESULTS: A total of 19,756 patients were hospitalized during the study period, and in 1,866 of them, NAUTI was reported. Proof of infection was reported in 1,395 patients. Resistance rates of all antibiotics tested other than imipenem against the total bacterial spectrum were higher than 10 % in all regions. Resistance to almost all pathogens was lowest in North Europe, and there is no single year where an outbreak of resistance has been detected. CONCLUSION: The resistance rates of most of the uropathogens against the antibiotics tested did not show significant trends of increase or decrease with Asia exhibiting the highest rates in general. The only antibiotic tested with an overall resistance rate below 10 % was imipenem. Knowledge of regional and local resistance data and prudent use of antibiotics are necessary to optimize antibiotic therapy in urological patients with NAUTI.
