Abstract
OBJECTIVES The aim of this study was to investigate the association of lower urinary tract dysfunctions with urinary leakage from ureterocystoneoanastomosis (UCNA) after kidney transplantation. BACKGROUND The UCNA leakage after kidney transplantation can be associated with various conditions while severe lower urinary tract dysfunctions could be one of them. METHODS The analysis included all men who underwent kidney transplantation between January 2009 and December 2014. The parameters of storage and voiding functions were evaluated. All patients were monitored during their post-transplantation period for the incidence of urinary leakage from UCNA. Urodynamic parameters were compared between men with and without a documented leakage. RESULTS The study cohort included 127 male patients, while UCNA leakage was observed in 11 (8.7 %) patients. Significant differences between both groups of patients were found for storage parameters (patients with leakage had smaller volume at first and a normal desire to void, smaller maximal cystometric capacity, and lower detrusor compliance) and voiding parameters (patients with leakage had a lower maximal flow rate, higher detrusor pressure at maximal flow rate and higher bladder outlet obstruction index). CONCLUSION This study shows an association between lower urinary tract dysfunction and UCNA leakage in men without previous urological history (Tab. 2, Fig. 2, Ref. 24).

Abstract
Hepatitis C virus infection is causing chronic liver disease, cirrhosis, and hepatocellular carcinoma. By combining direct-acting antivirals (DAAs), high sustained virologic response rates (SVRs) can be achieved. Resistance-associated substitutions (RASs) are commonly observed after DAA failure, and especially nonstructural protein 5A (NS5A) RASs may impact retreatment options.1-3 Data on retreatment of DAA failure patients using first-generation DAAs are limited.4-7 Recently, a second-generation protease- and NS5A-inhibitor plus sofosbuvir (voxilaprevir/velpatasvir/sofosbuvir [VOX/VEL/SOF]) was approved for retreatment after DAA failure.8 However, this and other second-generation regimens are not available in many resource-limited countries or are not reimbursed by regular insurance, and recommendations regarding the selection of retreatment regimens using first-generation DAAs are very important. This study aimed to analyze patients who were re-treated with first-generation DAAs after failure of a DAA combination therapy.

Abstract
Zusammenfassung
Ziel: Ziel dieser Studie war, die diagnostische Aussagekraft der 111In-Oc-treotide- und der 123I-MIBG-Szintigraphie an einem größeren Patientengut in der Diagnostik von Karzinoiden zu vergleichen und mit computertomographischen Befunden zu korrelieren. Methoden: Bei 28 Patienten wurden in engem zeitlichen Intervall eine Octreotide-, MIBG-Szintigraphie und Computertomographie durchgeführt. Ergebnisse: Bei 13/15 präoperativ untersuchten Patienten konnte eine Rezeptorexpression des Primärtumors mit Octreotide nachgewiesen werden, eine MIBG-Speicherung lediglich bei 8/15 Fällen. Lebermetastasen waren im Octreotide-Szintigramm in 26 Fällen nachweisbar, mit MIBG in 19 Fällen, computertomographisch bei 22 Patienten. Die Zahl der gefundenen Herde war mit MIBG und CT geringer als mit Octreotide. Drei Patienten wiesen bisher unbekannte, extrahepatische Octreotide-Mehrspeiche-rungen auf, 2 davon zeigten keine MIBG-Speicherung. Fünf nichthormonaktive Tumoren waren im MIBG-Szintigramm negativ, wurden aber im Octreotide-Szintigramm nachgewiesen. Schlußfolgerung: Hinsichtlich der diagnostischen Möglichkeiten ist die Octreotide-Rezeptor-szintigraphie der MIBG-Szintigraphie deutlich überlegen. Somit bringt die Durchführung der MIBG-Szintigraphie nach der vorliegenden Studie keinen diagnostischen Zugewinn und erscheint nur im Hinblick auf eine eventuelle 131I-MIBG-Therapie sinnvoll.

Abstract
OBJECTIVE Many clinical studies indicate that pharmacologic treatment of overactive bladder (OAB) is considered effective and safe, but in real clinical practice a substantial proportion of patients discontinues the treatment. The reason for discontinuing the treatment most frequently reported is lack of efficacy and/or side effects. A further significant proportion of patients reports that they stopped the treatment because the symptoms disappeared or were resolved. This β3 agonist seems to be crucial in providing comparable efficacy in the OAB treatment and better tolerance in comparison with anticholinergics. Our aim was to investigate the durability of the mirabegron effect in successfully treated OAB patients and to understand more fully what prompts patients to return to the medication. Is this merely a subjective decision, or is it based on objective worsening of the symptoms? DESIGN Analysis of multicentre prospective study. SETTINGS Gynaecology and Obstetric Department First Faculty of Medicine, Charles University and General University Hospital, Prague. METHODS This is an analysis of longitudinal multicentre study of OAB mirabegron treatment persistence. After continuing mirabegron treatment for more than 18 months patients were assessed by bladder diary and specific questionnaires. Patients with a UB-VAS score (Urgency Bother Visual Analogue Scale) of 50 or less were asked to stop the mirabegron treatment and restart the treatment any time later if they felt the need. Patients recorded the date of return to medication; they kept a daily bladder diary and filled in the same questionnaires as at the time of medication discontinuation. We provide a comparison of symptoms at the time of mirabegron discontinuation and at the time of mirabegron medication restart. RESULTS 206 patients entered the study. 176 females (85%) and 30 males (15%) with mean age 62.9 ± 12.43, BMI ranging from 16.6 to 48.0 (mean 27.2 ± 4.96). After 18 months 126 patients were persisting with mirabegron treatment. 89 patients had UB-VAS score 50 (89 of 126 patients, i.e. 71%). Those patients were asked to stop the treatment. From the eligible group of 89 patients, 19 patients (21%) were unwilling to stop the treatment and were therefore excluded. There were no significant differences in bladder diary and QoL characteristics between patients who were unwilling to discontinue the treatment and patients who did stop taking the medication. The group who stopping treatment comprised 70 patients. At the time of last follow-up 22 patients (31%) had not restarted the medication, with mean follow-up of 122.6 days. Therapy was restarted by 48 patients (i.e. 69% of 70). The mean time without treatment was 48 days (± 32.0 days), median 53 days. There was significant worsening of OAB symptoms and subjective bother at the time of restarting the medication. CONCLUSION Subjective bother based on increase number of frequency, urgency, and nycturia causes patients with positive experience to return to mirabegron treatment. Most patients with successfully-treated symptoms of OAB who discontinue treatment can only do so temporarily. A worsening of the symptoms occurs rather rapidly, because 69% of patients with OAB symptoms successfully treated with mirabegron (UB-VAS 50) are unable to discontinue taking the medication for more than two months.

Abstract
The study aim was to determine whether there is a correlation between subclinical forms of genitourinary tuberculosis (GUTB) and immune status. All patients admitted to the Pneumology Clinic of the Thomayer Hospital, Prague with lung tuberculosis (LTB) were enrolled in the study. The study group consisted of 102 patients, 75 males and 27 females, median age of 46.8 years. In a previously published part of the study, 6.9 % of LTB patients were diagnosed with subclinical forms of GUTB. In the present part of the study, immune status was determined in patients with subclinical forms of GUTB by measuring circulating immunoglobulin G and CD4 T cell levels. The comparison of the immunological results did not show a statistically significant difference between the patients diagnosed with GUTB and other LTB patients..

Abstract
The aim of the study was to characterize by molecular profiling two glomerular diseases: IgA nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS) and to identify potential molecular markers of IgAN and FSGS progression. The expressions of 90 immune-related genes were compared in biopsies of patients with IgAN (n=33), FSGS (n=17) and in controls (n=11) using RT-qPCR. To identify markers of disease progression, gene expression was compared between progressors and non-progressors in 1 year follow-up. The results were verified on validation cohort of patients with IgAN (n=8) and in controls (n=6) using laser-capture microdissection, that enables to analyze gene expression separately for glomeruli and interstitium. In comparison to controls, patients with both IgAN and FSGS, had lower expression of BAX (apoptotic molecule BCL2-associated protein) and HMOX-1 (heme oxygenase 1) and higher expression of SELP (selectin P). Furthermore, in IgAN higher expression of PTPRC (protein-tyrosine phosphatase, receptor-type C) and in FSGS higher expression of BCL2L1 (regulator of apoptosis BCL2-like 1) and IL18 compared to control was observed. Validation of differentially expressed genes between IgAN and controls on another cohort using laser-capture microdissection confirmed higher expression of PTPRC in glomeruli of patients with IgAN. The risk of progression in IgAN was associated with higher expression EDN1 (endothelin 1) (AUC=0.77) and FASLG (Fas ligand) (AUC=0.82) and lower expression of VEGF (vascular endothelial growth factor) (AUC=0.8) and in FSGS with lower expression of CCL19 (chemokine (C-C motif) ligand 19) (AUC=0.86). Higher expression of EDN1 and FASLG along with lower expression of VEGF in IgAN and lower expression of CCL19 in FSGS at the time of biopsy can help to identify patients at risk of future disease progression.

Abstract
OBJECTIVE The objective of this study was to monitor and evaluate the persistence and cure effect of Mirabegron in patients with overactive bladder syndrome after 18 months of treatment. DESIGN Prospective clinical study. SETTINGS 10 gynecological and urological departments in CZE. MATERIALS AND METHODS This is an analysis of a prospective, multicenter monitoring study from May to September 2014. The patients were 18 years old and had symptoms of OAB for a minimum of three months. Patient check-ups were performed 18 months after the first visit. The dosage of Mirabegron was 50 mg per day in 162 patients, though for 44 of the patients the treatment was changed. During the final check-ups it was ascertained how many patients had discontinued treatment with Mirabegron, at first as a proportion of the whole group of patients and then in relation to gender, age, previous treatment with anticholinergic drugs and changes in the treatment during the study. To evaluate treatment efficacy we employed the TS-VAS and PPBC. During the check-up it was ascertained how many patients had discontinued treatment with Mirabegron, and reasons for this were established. The statistics were calculated using the softwares STATISTICA 12 (Statsoft, USA) and SPSS 20.0 (IBM, v.20.0). RESULTS Prospective monitoring was performed on 206 patients. Their mean age was 62.8 years; mean body mass index for the whole group of patients was 27.3. At the check-up 18 months post-initiation of treatment it emerged that 79 (38.3%) patients had discontinued the treatment. The reasons for discontinuation of treatment were insufficient treatment efficacy (35.4% of patients), while 49.4% cited other reasons (hospitalisation, surgery, gravidity) and 15.2% of patients discontinued therapy because of side effects. The evaluation of treatment persistence with Mirabegron in groups with relation to gender, age and previous treatment with anticholinergic drugs did not establish statistically significant differences. However, there was a statistically significant difference between groups in relation to changes of treatment during study. At the evaluation of the efficacy of the treatment during the check-up 18 months after initiation of treatment the mean TS-VAS was 73.4, a decrease of the scale of bothers evaluated by PPBC before treatment from a mean value of 4.6 to a value of 2.7. CONCLUSIONS In our clinical study 18 months treatment persistence with Mirabegron was 61.7%. The reasons were reduced side effects and good cure effect of the drug.

Abstract
OBJECTIVE Overactive bladder syndrome is chronic disease with high prevalence rate (9-42%). This syndrome requires long term therapy, but the treatment persistence is after 3 months over all 26% with further decline in one-year period as low as 18.5%. Main reasons for stopping the treatment are low efficacy, the medication didnt work as expected and side effects. How much satisfied are patients with mirabegron persisting on its treatment? To answer this question, we provided secondary analysis of multicentre follow-up study of patients on mirabegron. We compared subjective and objective parameters between patients continuing mirabegron treatment and those who discontinued the medication. DESIGN Secondary analysis multicentre prospective follow-up. SETTINGS Ob/Gyn department First Faculty of Medicine, Charles University and General University Hospital, Prague. METHODS It is secondary analysis of multicentre prospective study following patients with mirabegron 50 mg treatment. We have analysed objective data from micturition diary and subjective data using visual analogue scales (UB-VAS - urgency bother visual analogue scale, and TS-VAS - treatment satisfaction visual analogue scale) and compared data between the group of patients continuing mirabegron treatment and patients who stopped the medication during the study. RESULTS We included 206 patients (176 women, 30 men) with diagnosis of overactive bladder. Patients continuing the treatment (group n1) had baseline UB-VAS 70.1 vs. 75.0 (p = n.s.) in patients who stopped the medication during the follow-up period (group n2). Baseline episodes of severe urgency and urge incontinence where n1 - 5.1 vs. n2 - 6.2 (p = n.s.). Six months urgency bother score UB-VAS was n1 - 32.4 vs. n2 - 58.9 (p < 0,001). Treatment satisfaction TS-VAS was n1 - 80.3 vs. n2 - 57.7 (p < 0,001). Number of severe urgencies with or without urge incontinence was after 6 months n1 - 2.1 vs. n2 - 3.3 (p = n.s.), lower in group continuing the treatment. When comparing the data between patients stopping the medication for reason of low efficacy (group s1) with patients stopping for other reasons (group s2) UB-VAS bas: s1 - 68.5 vs. s2 - 43.9 (p = 0.001); TS VAS s1 - 45.1 vs. s2 - 58.4 (p = n.s.) and number of severe urgency with or without incontinence s1 - 5.9 vs. s2 - 3.2 (p = 0.009). CONCLUSION Our data shows that patients expectation on treatment with mirabegron is not low. Patients accept treatment either without side effects or with decrease of severe urgency with or without urge incontinence around 50%. Regardless the reason the patients continuing the treatment scale treatment satisfaction - TS-VAS over 70 points.

Abstract
With the approval of new direct acting antiviral agents (DAA), therapeutic options for patients with chronic hepatitis C virus (HCV) infection are now generally available before and after liver transplantation (LT). Interferon-free DAA regimens are highly effective therapies and provide a good safety profile. However, the body of clinical evidence in this patient population is limited and the best treatment strategies for patients on the waiting list with (de)compensated cirrhosis and after LT are not well defined. The following recommendations for antiviral therapy in the context of LT are based on the currently available literature and clinical experience of experts in the field, and have been discussed in an expert meeting. The aim of this article is to guide clinicians in the decision making when treating patients before and after LT with DAAs.

Abstract
PURPOSE Wilms tumor gene 1 (WT1), a zinc-finger transcription factor essential for testis development and function, along with other genes, was investigated for their role in the pathogenesis of testicular germ cell tumors (TGCT). METHODS In total, 284 TGCT and 100 control samples were investigated, including qPCR for WT1 expression and BRAF mutation, p53 immunohistochemistry detection, and massively parallel amplicon sequencing. RESULTS WT1 was significantly (p < 0.0001) under-expressed in TGCT, with an increased ratio of exon 5-lacking isoforms, reaching low levels in chemo-naïve relapsed TGCT patients vs. high levels in chemotherapy-pretreated relapsed patients. BRAF V600E mutation was identified in 1% of patients only. p53 protein was lowly expressed in TGCT metastases compared to the matched primary tumors. Of 9 selected TGCT-linked genes, RAS/BRAF and WT1 mutations were frequent while significant TP53 and KIT variants were not detected (p = 0.0003). CONCLUSIONS WT1 has been identified as a novel factor involved in TGCT pathogenesis, with a potential prognostic impact. Distinct biologic nature of the two types of relapses occurring in TGCT has been demonstrated. Differential mutation rate of the key TGCT-related genes has been documented.

Abstract
AIMS To investigate the effect on urodynamics of 4 weeks treatment with solifenacin succinate in patients with neurogenic detrusor overactivity (NDO) due to multiple sclerosis (MS) or spinal cord injury (SCI). METHODS SONIC was a prospective, multicenter, double-blind, phase 3b/4 study investigating the efficacy and safety of solifenacin 10 mg in patients with NDO due to MS or SCI. Patients (n = 189) were randomized to placebo or active treatment (solifenacin 5 mg, 10 mg or oxybutynin hydrochloride 15 mg) for 4 weeks, after a 2-week, single-blind, placebo run-in period. The primary endpoint was change in maximum cystometric capacity (MCC) from baseline to end of treatment. The primary analysis compared solifenacin 10 mg versus placebo; all other comparisons were considered secondary. Secondary endpoints included changes in urodynamic parameters, patient-reported outcomes, and safety assessments. RESULTS In the primary analysis, solifenacin 10 mg significantly improved mean change from baseline MCC versus placebo (P < 0.001) and was associated with improvements in bladder volume at first contraction and at first leak as well as detrusor pressure at first leak. Similar results were obtained for oxybutynin versus placebo. Patient perception of bladder condition significantly improved with solifenacin 10 mg versus placebo (P = 0.041). There was a clear improvement in quality of life (QoL) in the solifenacin arms versus placebo. The overall incidence of adverse events was low. CONCLUSIONS In patients with NDO due to MS and SCI, 4 weeks of treatment with solifenacin 10 mg improved urodynamic variables and QoL versus placebo and was well tolerated. Neurourol.

Abstract
PURPOSE The aim of the present prospective European multicenter study was to demonstrate the non-inferiority of point shear wave elastography (pSWE) compared to transient elastography (TE) for the assessment of liver fibrosis in patients with chronic hepatitis C. MATERIALS AND METHODS 241 patients with chronic hepatitis C were prospectively enrolled at 7 European study sites and received pSWE, TE and blood tests. Liver biopsy was performed with histological staging by a central pathologist. In addition, for inclusion of cirrhotic patients, a maximum of 10 % of patients with overt liver cirrhosis confirmed by imaging methods were allowed by protocol (n = 24). RESULTS Owing to slower than expected recruitment due to a reduction of liver biopsies, the study was closed after 4 years before the target enrollment of 433 patients with 235 patients in the 'intention to diagnose' analysis and 182 patients in the 'per protocol' analysis. Therefore, the non-inferiority margin was enhanced to 0.075 but non-inferiority of pSWE could not be proven. However, Paired comparison of the diagnostic accuracy of pSWE and TE revealed no significant difference between the two methods in the 'intention to diagnose' and 'per protocol' analysis (0.81 vs. 0.85 for F ≥ 2, p = 0.15; 0.88 vs. 0.92 for F ≥ 3, p = 0.11; 0.89 vs. 0.94 for F = 4, p = 0.19). Measurement failure was significantly higher for TE than for pSWE (p = 0.030). CONCLUSION Non-inferiority of pSWE compared to TE could not be shown. However, the diagnostic accuracy of pSWE and TE was comparable for the noninvasive staging of liver fibrosis in patients with chronic hepatitis C.

Abstract
OBJECTIVES To evaluate the presence of hormonal abnormalities and fertility disorders in patients with chronic kidney disease (CKD) awaiting renal transplantation. METHODS From September 2009 to April 2011 all male patients with CKD awaiting kidney transplantation were investigated. The following tests were performed: semen analysis, serum concentration of testosterone, SHBG, LH, FSH and prolactin. Differences in hormone levels and sperm count parameters were statistically evaluated between the control group and the patient group. RESULTS The group of patients consisted of 74 and the control group of 41 men. Average testosterone levels were lower in patients compared to control group. In patients significantly higher levels of SHBG, LH, FSH and PRL were found, and statistically significantly lower ejaculate volume, total sperm count, sperm concentration, total and progressive sperm motility and sperm morphology than in the control group. Within the group of patients a negative correlation between testosterone and PRL was found and a positive correlation between testosterone and total sperm motility and morphology. A negative correlation was detected between the duration of haemodialysis and testosterone, sperm concentration, total and progressive motility and sperm morphology. CONCLUSION Significant changes in hormone levels and impaired fertility are found in haemodialyzed patients on a waiting list for kidney transplantation. The dynamics of these changes are dependent on the duration of haemodialysis (Tab. 4, Fig. 2, Ref. 15). Text in PDF www.elis.sk.

Abstract
Nocturia is the complaint that the individual has to wake at night one or more times to void, according to the International Continence Society definition from the ICS Standardisation of Terminology Report 2002. As the nocturia definition is complicated there are also other slightly modified definitions. It is currently not absolutely clear if prevalence or incidence is more important for epidemiology evaluation of nocturia. Nocturia is a variable symptom and its presence in individuals is reversible therefore it is very difficult to obtain reliable incidence data. Nocturia prevalence varies remarkably in different studies according to evaluation methodology, nocturia definition, methods of data collection and characteristics of evaluated population. There are not enough studies, especially demographic ones, evaluating lower urinary tract symptoms and/or nocturia in males and females. There is relatively large number of comparative studies confirming strong correlation between aging and prevalence of nocturia. Prevalence of two or more voids per night in individuals in their twenties varies between 5-15 %, it progresses with age, and in the seventh decade of life ranges between 35-50 %. Prevalence evaluated by gender is higher among younger women compared to older women and older men compared to younger men. Currently there are only limited sources of data regarding nocturia incidence. Incidence of nocturia (two or more voids per night) in a population older than 60 years is 213 new cases/1000 persons/1 year in two year observation. Incidence of two or more voids per night is 75 new cases/1000 male/1 year in five year observation and 126 new cases/1000 male/1 year in ten year observation in male population. Incidence of nocturia rises significantly with age. Incidence of two or more voids per night increases by 2,7 % in the population of women after child birth during 5 year follow up and by 5,9 % during 12 year follow up. Incidence of nocturia newly diagnosed in a pregnancy drops down by 98% in 3 month after the child birth. The incidence data indicate that incidence of nocturia rises with age and probability of nocturia relief decreases with age. Incidence of mild nocturia is higher compared to incidence of severe nocturia and significant relief of nocturia in women after child birth is very inconsistent compared to increase of other lower urinary tract symptoms. Ethiology of nocturia might be polyuria, nocturnal polyuria or reduced bladder capacity. Nocturia and its ethiology can be determined in most cases with simple and commonly used investigative methods on the out-patients bases. The diagnostic algorithm should lead to verification of nocturia and identifying its cause because treatment of nocturia differs remarkably according to the etiology.

Abstract
UNLABELLED Nonpharmacologic and especially pharmacologic treatment options are available for nocturnal polyuria. Desmopressin represents the basis of pharmacologic treatment. Desmopressin acetate is a synthetic analogue of arginine vasopressin with high affinity to V2 receptors with antidiuretic effect. It is the only medicament currently registered for antidiuretic treatment. Desmopressin has not any relevant affinity to V1 receptors, and therefore there is no hypertensive effect in contrary to natural vasopressin. Desmopressin use before a bedtime leads to reduced production of urine during a sleep, therefore time between desires to void is prolonged and number of nocturia is reduced. Clinical effect, in a meaning of reduced urine production and increased osmolality of urine, lasts approximately 8-12 hours. In the treatment of nocturnal polyuria desmopressin is used orally one hour before a bedtime. It is essential to titrate an ideal dose, the initial dose is 60 µg of MELT formula (fast melting oral formulation) and it can be increased according to the clinical effect up to the maximal recommended daily dose 240 µg. Patients treated with desmopressin should cut down a fluid intake 1 hour before and 8 hours after the use of desmopressin. Total number of adverse events connected withdesmopressin treatment in clinical studies was higher compared to placebo but the side effects were mostly mild. The most common adverse events were headaches, nausea, diarrhoea, abdominal pain, dry mouth and hyponatremia both in the short-term and long-term clinical trials. Hyponatremia was observed mainly in patients over 65 year of age. Therefore treatment with desmopressin should not be commended in patients over 65 year of age without close monitoring of the natrium level in serum and all patients should be informed about the first symptoms of hyponatremia - headache, nausea and insomnia. According to Evidence Based Medicine, the level of evidence for treatment of nocturnal polyuria with desmopressin is 1b and the grade of recommendation for treatment is A. KEYWORDS nocturnal polyuria - treatment - desmopressin.

Abstract
BACKGROUND Biliary complications (BCs) and recurrent hepatitis C virus (HCV) infection are among the major causes of morbidity and graft loss following liver transplantation. The influence of HCV on BCs has not been definitely clarified. PATIENTS AND METHODS We performed a retrospective cohort study to analyze risk factors and outcome of post orthotopic liver transplantation (OLT) BCs in 352 liver transplant recipients over 12 years in Munich, Germany (n = 84 with HCV; living donor and re-OLT were excluded). BCs diagnosed with imaging techniques and abnormal liver enzyme pattern, requiring an intervention, were considered. RESULTS In a multivariate analysis, HCV serostatus and a high pre-and post-surgery HCV RNA serum load were independent risk factors for anastomotic strictures. HCV positivity and BCs alone did not alter graft loss. HCV-positive patients with BCs, however, had a significantly worse graft outcome (P = 0.02). Non-anastomotic strictures, bile leaks, and the number of interventions needed to treat bile leaks led to worse graft outcome in all patients. CONCLUSION HCV positivity and a high HCV RNA serum load were risk factors for anastomotic strictures. BCs and HCV had an additive effect on graft loss.

Abstract
INTRODUCTION Overactive bladder (OAB) presents one of the most frequent medical problems among the current adult population, with a significant impact on the quality of life of the affected patients. A questionnaire survey was carried out in 2006, with the aim to assess the level of knowledge regarding the problem of OAB among gynaecologists and urologists in the Czech republic, as well as to evaluate the currently applied methods of OAB diagnostics and treatment. The aim of this work was to perform a repeated survey after five years, and to evaluate, whether there have been any changes achieved in the monitored parameters. MATERIALS AND METHODS A total of 290 respondents (181 gynaecologists, 109 urologists) were included in the survey in 2006; the study group in 2011 included a total of 285 respondents (180 gynaecologists, 105 urologists). The questionnaire used for the survey in 2011 was identical to the document utilized in the initial survey performed five years ago, with minimal changes. The anonymous questionnaire was designed as "multiple-choice", i.e. with a possible selection from proposed answers; the questions were targeted at the topics of definition, diagnostics and therapy of OAB. The obtained results were processed with the methods of descriptive statistics; the concordance of proportions was evaluated with the Fishers exact test. RESULTS A total of 114 gynaecologists (63.3%), and 65 urologists (61.9%) were able to determine the correct definition of OAB, which presents a significant increase when compared to 2006 (p<0.0001). The most frequently applied methods of OAB diagnostics were patient history (gynaecologists: 97.8% in 2011 vs. 96.5% in 2006, urologists: 99.0% in 2011 vs. 99.0% in 2006), local examination (gynaecologists: 57.8% vs. 76.4%, urologists: 86.7% vs. 87.2%), bladder diaries (gynaecologists: 62.8% vs. 40.3%, urologists: 79.0% vs. 60.5%), and urine examination (gynaecologists: 71.1% vs. 82.3%, urologists: 96.2% vs. 97.1%). Anticholinergic medication is the first-choice in the OAB treatment in our conditions, which has been confirmed by 146 (81.1%) gynaecologists, and 89 (84.4%) urologists. In cases when the physicians use anticholinergic medication for the treatment of OAB, the first-choice medication is trospium, among both gynaecologists and urologists. In case of failure of the first-choice treatment, twenty-six (14.4%) gynaecologists from the addressed respondents try to continue with a treatment according to their own decision, 154 (85.6%) gynaecologists refer the patient to a specialist. Similarly, a total of 90 (85.7%) urologists try to manage the further course of treatment by their own means, 15 urologists (14.3%) refer the patient to a specialist. CONCLUSION The level of understanding and awareness about the problem of OAB among the Czech gynaecologists and urologists has significantly improved during the past five years. The applied diagnostic and treatment methods for OAB are being harmonized with the International Continence Society (ICS) recommendations. Taking into consideration the prevalence of OAB among the population, it is desirable to increase the number of clinical departments who deal with the problem of OAB in a complex manner. The remaining significant task lies in the improvement of foreknowledge about the current possibilities and effectiveness of the OAB treatment among the patient population.

Abstract
OBJECTIVE The aim of our study is to present initial experiences, with regard to safety and short-term efficacy, of mini-sling MiniArc and AJUST operations for stress urinary incontinence (SUI). DESIGN Cross-sectional clinical study. SETTINGS Gynecological and Obstetric Clinic 1. LF UK and VFN Prague; Gynecological and Obstetric Clinic FN Bulovka and 1. LF UK Praha; Urological dpt. FTN Prague; GONA spol. s r.o.; Urological dpt. FN Ostrava Poruba. MATERIALS AND METHODS We present briefly the technique employed in the operations, the urodynamic examination procedure before and after the operation, and the subjective and objective outcomes of these procedures from the 5 above-mentioned hospitals which participated on the study. Objectively the leakage of urine was assessed during urodynamic examination and by cough test. Subjectively leakage of urine was assessed by ICIQ-SF questionnaire (The International Consultation on Incontinence, short form). This study evaluated the cure effect and complications accompanying the MiniArc and AJUST procedures, and compared these results. The clinical study included 66 women with previously untreated stress urinary incontinence. These women were randomly divided by envelop method into two groups; the first group of patients underwent operations using the MiniArc (n=33) technique and the second group the AJUST (n=33) technique. Mean age was 57.9 years in the AJUST group and 57.7 years in the MiniArc group. Mean body mass index (BMI) was 29.2/28.7 in the AJUST/MiniArc groups respectively, and mean parity was 2.09/2.24. We did not find statistically significant differences between these two groups. RESULTS The curative rate of the MiniArc and AJUST procedure was evaluated 3 months after the operation (+/- 1 week). We can conclude from the outcomes of the cough test that this test was negative in 61 (92%) of patients overall; in the AJUST group it was 31 (94%) of patients and in the MiniArc group 30 (91%) of patients. In the subjective evaluation of the leakage of urine before operation (ICIQ-SF) the mean score in the group of patients who subsequently underwent the AJUST operation was 15.4 (SD-3.39; median-16, range 8-21) and in women who underwent the MiniArc operation it was 15.5 (SD-3.3; median-16, range 8-21). The AJUST/MiniArc procedure caused a statistical significant decrease in the total score to -14.09(SD-5.18)/-14.45 (SD-3.73). The difference in the decrease of the score between the AJUST/MiniArc groups was not statistically significant. In the AJUST group of patients, according to the ICIQ-SF, 30 (91%) women were without problem or improved [27 (81.7%) of women were without problem], while in the MiniArc group 32 (96.9%) were without problem or improved [24 (72.7%) of women were without problem]. The urodynamic examination before and after operation indicated that there were no differences between the groups of patients either before and or after the operation. Changes in the parameters MUCP, Qmax and others caused by the operation were not significant, and there were no statistical significant differences in the values of these parameters between the groups of patients. Complications of the MiniArc and AJUST procedures were not recorded. CONCLUSIONS Our first experiences with MiniArc and AJUST procedures, including possible complications and curative rate, are positive. From the preliminary results the cure effect of MiniArc and AJUST 3 months after the operation (+/- 1 week) is similar. It will be important to evaluate the efficacy of these procedures one year after the operation for a definitive evaluation of the cure effect.

Abstract
PURPOSE Acoustic Radiation Force Impulse Imaging (ARFI) is a new ultrasound elastography technology (Siemens ACUSON S2000 Virtual Touch™ Tissue Quantification), which is integrated in conventional ultrasound equipment. In preliminary studies, ARFI sheer wave speed (SWS) in liver tissue correlated well with transient elastography (TE) values and liver fibrosis stages. MATERIALS AND METHODS Sixty-eight healthy male and female volunteers were measured with ARFI with two ultrasound tranducers, three measuring positions and during valsalva manoeuvre. A TE (FibroScan™, Echosens, France) was performed in 60 volunteers. RESULTS Volunteers had a mean age of 28 years and a mean BMI of 22.3. There was no significant difference of ARFI SWS between the 4C1 and 4V1 ultrasound probes in either intercostal or abdominal approach to liver segment 8 but a higher variance of ARFI SWS with the 4V1/abdominal compared to the intercostal approach (p = 0.0368). The 4C1/intercostal approach had the highest success rates (97.2%), comparable to those of TE (97.18%). Left liver lobe measurements obtained both significantly higher ARFI SWS and value variance (p = 0.0016 and p = 0.0198) compared to 4C1/intercostal approach. Mean ARFI SWS was 1.19 m/s (range 0.77-1.63). Mean TE was 5.39 kPa (range 3.3-9.0 kPa). Valsalva manoeuvre did not significantly alter ARFI SWS and variance. Skin-liver distance significantly influenced ARFI SWS (p < 0.05), while age and gender did not. CONCLUSION These results might constitute a first impression of the chances of ARFI SWS to assess liver stiffness, especially in patients with liver diseases due to increased venous pressure.

Abstract
HISTORY AND ADMISSION FINDINGS One month after a first manifestation of a hepatitis A infection and transaminases had become normal, a 44-year-old woman again became jaundiced with accompanied by weakness, nausea and nocturnal sweating. INVESTIGATIONS Laboratory tests again showed features of hepatitis with decreased synthetic liver function and hyperbilirubinemia, changes which persisted for 12 weeks. Serological and virological studies revealed a positive test for anti-hepatitis A virus (HAV) IgM and HAV-RNA was detected in the stool. DIAGNOSIS, TREATMENT AND COURSE These tests demonstrated two rare features of hepatitis A, namely a prolonged biphasic course combined with cholestasis form. In addition a hemolytic anaemia developed. CONCLUSION The severity of a relapse of hepatitis A varies: in this case it was more severe than the initial manifestation. The reasons for the different courses of hepatitis A infection remain unclear.

Abstract
INTRODUCTION The term OAB (overactive bladder) was introduced in praxis in the year 2002 by Abrams. This term includes symptoms of urgency, with or without urgent incontinence, and it is generally accompanied by urinary frequency and nocturia. OAB is widespread among our female population. Approximately 20% of women suffer from this problem, but the frequency of the syndrome has not been assessed more precisely by means of questionnaires. The aim of our study was to assess the prevalence of OAB among patients who visited gynecologists in the first line and completed the Bladder Control Self Assessment Questionnaire (BCSAQ). MATERIAL AND METHODS Five gynecologists in the first line questioned 492 consecutive patients as to whether they suffered from urgency, frequency, nocturia and urgent incontinence, and their answers were later evaluated. The BCSA questionnaires completed by the patients in the waiting room before seeing the doctor were subsequently also evaluated. RESULTS Due to inquiries made by the gynecologist, 320 patients took the BCSA questionnaires in the waiting room before seeing the doctor, and 314 completed them; 14 patients completed the questionnaires after seeing the doctor who questioned them about problems with urgency. The patients then handed the completed questionnaires to the nurse, i.e. the total of 328 questionnaires were assessed. 159 patients suffered from urgency, and 35% of these patients had problems with leakage of urine. In reply to the question: Is it difficult to hold urine when you have the urge to go? 22% of patients from the whole group of patients (n = 492) answered yes. 24% of patients had problems with frequency, 32% with nocturia and 14% with urgent incontinence. CONCLUSION OAB syndrome is widespread in our population; it constitutes a major problem which must be treated. Awareness of this problem has now improved; patients feel less embarrassed to discuss about problem, and increasingly they seek treatment, while at the same time gynecologists have improved their knowledge about the diagnosis and treatment of OAB. This means that the quality of life for these patients can be improved.

Abstract
BACKGROUND Study compares results of preoperative diagnostic methods with measurements of tumor extension in a specimen obtained by radical prostatectomy. METHODS AND RESULTS One hundred forty-six patients with clinically identified cancer were enrolled in the study and subjected to radical prostatectomy. Each patient underwent transrectal sonography (TRUS), Power Doppler sonography with 3D reconstruction (3D-PDS), and the risk of the occurrence of locally advanced tumor was assessed using Partin tables. In subgroups of localized and locally advanced tumor, individual preoperative parameters were compared. ROC curves were generated for individual preoperative parameters and the area under the curve (AUC) was calculated. Multivariate logistic regression analysis was performed to determine independent predictors of extraprostatic tumor extension. A statistically significant difference between patients with localized and locally advanced tumor was observed in PSA levels (p < 0.014), PSA density (p < 0.004), DRE (p < 0.037), TRUS (p < 0.003), and 3D-PDS (p < 0.000). The highest AUC value was found for 3D-PDS 0.776, TRUS 0.670, and PSA density 0.639. According to multivariate analysis, independent preoperative predictors of extraprostatic tumor extension were PSA density, preoperative Gleason score 7, and 3D-PDS finding. CONCLUSIONS Power Doppler sonography with 3D reconstruction represents the most reliable preoperative diagnostic tool in determining locally advanced tumor. Together with PSA density and the presence of aggressive tumor (Gleason score > or =7) in prostate biopsy, it is one of independent predictors of locally advanced prostate cancer.

Abstract
The hepatitis C virus (HCV)-specific CD4+ T-cell response against nonstructural proteins is strongly associated with successful viral clearance during acute hepatitis C. To further develop these observations into peptide-based vaccines and clinical immunomonitoring tools like HLA class II tetramers, a detailed characterization of immunodominant CD4+ T-cell epitopes is required. We studied peripheral blood mononuclear cells from 20 patients with acute hepatitis C using 83 overlapping 20-mer peptides covering the NS3 helicase and NS4. Eight peptides were recognized by > or = 40% of patients, and specific CD4+ T-cell clones were obtained for seven of these and three additional, subdominant epitopes. Mapping of minimal stimulatory sequences defined epitopes of 8 to 13 amino acids in length, but optimal T-cell stimulation was observed with 10- to 15-mers. While some epitopes were presented by different HLA molecules, others were presented by only a single HLA class II molecule, which has implications for patient selection in clinical trials of peptide-based immunotherapies. In conclusion, using two different approaches we identified and characterized a set of CD4+ T-cell epitopes in the HCV NS3-NS4 region which are immunodominant in patients achieving transient or persistent viral control. This information allows the construction of a valuable panel of HCV-specific HLA class II tetramers for further study of CD4+ T-cell responses in chronic hepatitis C. The finding of immunodominant epitopes with very constrained HLA restriction has implications for patient selection in clinical trials of peptide-based immunotherapies.

Abstract
The intermittent catheterization technique is considered at present to be one of pillars of the therapy of lower urinary tract dysfunction. The technique gradually became used also in the treatment of some non-neurogenic voiding dysfunctions. There are many ways, how the intermittent catheterization could be performed (methodology, catheter material and type, lubrication type and method, catheterization frequency). Authors provide an overview of present indications to use the treatment; they describe individual techniques and draw attention to the possible complications and their solution. Next they emphasize the necessity of individual approach to intermittent catheterization technique in individual patients in the broader context of general concept of treatment.

Abstract
BACKGROUND/OBJECTIVES 11beta-Hydroxysteroid dehydrogenase (11beta-HSD) enzymes convert cortisol into inactive cortisone and vice versa. While 11beta-HSD type 2 (mainly localized in the kidney) unidirectionally inactivates cortisol to cortisone, type I isoform (mainly localized in the liver) acts bidirectionally and can thus potentially restore cortisone to active cortisol. The aim of this pilot study was to investigate whether the serum cortisol:cortisone ratio is altered during the acute-phase response, possibly due to altered modulation of 11beta-hydroxysteroid dehydrogenase isoforms. METHODS Using liquid chromatography electrospray tandem mass spectrometry, cortisol and cortisone were measured in the serum of hospitalized patients with normal and abnormal CRP concentrations, the latter indicating acute-phase response. Fifteen unselected samples were analyzed, all with a CRP concentration within one of the following ranges to cover a wide range of CRP concentrations evenly: <5, 5-20, 21-50, 51-100, 101-200, and >200 mg/l. RESULTS In the heterogeneous study population, increased CRP concentrations significantly correlated with an increased cortisol:cortisone ratio (p < 0.001; r = 0.65, Spearman correlation coefficient). This correlation was independent of increased serum cortisol concentrations found by multivariate regression analysis. The median ratio was 6.4 (interquartile range 5.5-7.4; n = 30) in patients with a CRP concentration < or =20 mg/l, and 11.2 (interquartile range 8.8-13.9; n = 60) in patients with CRP >20 mg/l (p < 0.01). CONCLUSION The balance between serum cortisol and cortisone is altered during acute-phase response with a shift towards active cortisol, suggesting that 11beta-HSD isoenzymes play a role in the modulation of systemically available cortisol during acute illness.

Abstract
In spite of intense diagnostic testing, no cause for the chronically aggressive hepatitis of a 48-year old male patient was found. Evidence for an autoimmune process, however, could be derived from a high titer of pANCA. Only according to the revised criteria of the working group on autoimmune hepatitis, but not to the first version, it was possible to classify this as an autoimmune hepatitis. Despite of high-dose steroid treatment and accelerated preparation for liver transplantation the patient died of the complications of rapid liver failure. Thus, in case of unclear rapid progressive hepatitis, the revised criteria of autoimmune hepatitis should be reviewed early and with high priority and consequent high-dose steroid therapy and preparation for liver transplantation should be initiated. The prognostic impact of a high titer of pANCA in patients with autoimmune hepatitis remains to be established.

Abstract
A novel DNA sequence belonging to a new genotype of TT virus (TTV) was detected by long-distance PCR in the serum of a chronically HCV-infected patient. The isolate was designated KAV according to the patient's initials. Extending the sequence to full length revealed a 3705-nt viral genome, which is about 100 nucleotides shorter than the other TT-viruses. KAV showed common features with the TTV family, such as the organization of open reading frames and conserved noncoding regions. The largest open reading frame of KAV (ORF 1) was about 40 aa shorter than that of other TT-viruses. Overall sequence homology with known TTV isolates was less than 66%. Phylogenetic analysis poses KAV in one major group with three recently published TTV sequences. So KAV can be considered as a new genotype of the TTV family (provisionally designated genotype 28).

Abstract
The remarkably strong formation of the mycophenolic acid molecular ion from mycophenolic acid glucuronide during electrospray atmospheric pressure ionization in patients' serum samples is described. It is concluded that because of this effect appropriate chromatographic separation prior to tandem-mass spectrometric analysis and correct peak detection and integration of the respective multiple reaction monitoring traces is mandatory probably in all cases where conjugate drug metabolites are present in post-dose samples.

Abstract
PSA is the most important of all tumor markers because it has significant applications in all aspects of the management of men with prostatic disease. Certainly, the most important utilization of PSA is for early detection of this most ubiquitous of all human neoplasms. In this article the authors describe the molecular forms of PSA and their characteristics, the factors influencing values of serum concentration of PSA, the problems of screening, and particularly the possibility to use PSA for detection of prostate carcinoma. A big problem in prostate carcinoma detection is the low specificity of PSA at the concentrations between 4-10 ng/ml, the so-called diagnostic gray zone, where the incidence of prostate carcinoma is only 25%. The authors evaluate the methods which make it possible to increase the sensitivity and/or specificity of PSA detection, such as PSA density, PSA density of the transition zone, PSA velocity, PSA doubling time, age-specific PSA, free PSA and, prospectively, the use of the RT-PCR technique.

Abstract
BACKGROUND AND PURPOSE Ureterointestinal anastomotic stricture follows urinary diversion in 4% to 8% of patients and may lead to a progressive deterioration of renal function. There are problems with all current management techniques: surgical revision, endourologic incision, nephrostomy drainage, external ureteral stents, and dilation with a high-pressure angioplasty balloon. The authors present their long-term results with permanent ureteral Wallstents for the treatment of benign ureterointestinal stricture. PATIENTS AND METHODS Eight patients with 10 strictures were treated by placement of self-expanding permanent indwelling stents via percutaneous nephrostomy between September 1993 and January 1998. The mean age of the group was 59.2 years. Development of strictures occurred a mean of 20.9 months after urinary diversion. There were seven complete and three partial strictures. Of 49 patients treated by the Camey procedure, 7 patients (14%) developed 9 (18%) strictures. Of 28 patients having the Wallace procedure, 1 patient (3.5%) developed one stricture. After recanalization of the distal ureter by a Terumo guidewire and dilation with a high-pressure angioplasty balloon, a Wallstent was placed across the stricture via a percutaneous approach. RESULTS The endourologic placement of the Wallstent was well tolerated by all patients. The hospital stay averaged 2 days. Seven patients with nine strictures after the Camey procedure are doing well with a follow-up of 7 to 68 months (mean 22.4 months). One major complication was observed in one patient necessitating an additional procedure (lithotripsy) because of stone formation at the lower part of the stent extending into the neobladder in order to maintain patency after 68 months. The other patient, who had a Wallace procedure, is doing well 1 year 8 months afterward. CONCLUSION An endourologic ureteral Wallstent approach to ureterointestinal stricture is a successful alternative, providing satisfactory management of the problem in most patients. No complication such as stent migration, hematuria, pain, or recurrent stricture was observed.

Abstract
BACKGROUND/AIMS Hyperlipoproteinemia is frequent following liver transplantation and may lead to atherosclerosis. Lipid-lowering agents may be useful, but could interfere with the function of the transplanted organ and with immunosuppression. We therefore evaluated in a prospective, randomized, open-labeled cross-over trial the effect of two frequently used 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (pravastatin 10 mg d(-1) and cerivastatin 0.1 mg d(-1)) in hyperlipoproteinemic patients after liver transplantation. METHODS Sixteen patients (6.3 +/- 2.0 years post-transplantation, cyclosporine n = 11, tacrolimus n = 5) with hyperlipoproteinemia (cholesterol 246 +/- 42, triglycerides 191 +/- 87, low-density lipoprotein (LDL)-cholesterol 161 +/- 35, high-density lipoprotein (HDL)-cholesterol 44 +/- 11 mg d(-1)) were included. Treatment periods of 6 weeks were separated by a 4-week washout period. RESULTS Both medications were tolerated well, no effects on serum concentrations of liver enzymes or immunosuppressive agents were observed. Cerivastatin and pravastatin decreased (P < 0.001) cholesterol by 21 +/- 10% and 15 +/- 10%, LDL-cholesterol by 27 +/- 14% and 17 +/- 15%, respectively, while triglyceride and HDL-cholesterol concentrations did not change significantly. LDL/HDL-cholesterol markedly improved (P < 0.001) by 29 +/- 16% (cerivastatin) and 16 +/- 16% (pravastatin). Cerivastatin was more potent than pravastatin in patients receiving cyclosporine A, while there was no significant difference in patients receiving tacrolimus. CONCLUSIONS Low-dose cerivastatin and pravastatin significantly improve lipid profiles following liver transplantation without affecting liver function or immunosuppression.
