[Nationwide survey among institutes of microbiology in academic medicine : Is the interdisciplinary approach the right way to treat patients with urogenital infections?] / Infektiologisch interessierte Urologen werden gebraucht : Nationale Umfrage universitärer Mikrobiologien zur interdisziplinären Zusammenarbeit von Urologie und Mikrobiologie.

BACKGROUND: Increasing antibiotic resistance is a current and severe problem in medicine, especially in urology. Multidisciplinary antibiotic stewardship programmes are an important approach to counteract increasing resistance rates. This approach includes collaboration between urologists and microbiologists. OBJECTIVES: The primary endpoint was to describe the current setting of interdisciplinary work of urologists and microbiologists in university hospitals in Germany. The secondary endpoints were the identification of problems of this interdisciplinary approach in daily routine and implications for the future in patient treatment. MATERIALS AND METHODS: A newly developed, 24-item questionnaire was sent to 34 German microbiology departments at medical universities between June and October 2016; the departments were contacted up to four times. Only complete questionnaires were included in our analysis. RESULTS: The response rate was 50.0%. In the majority of the urological cases a microbiologist was only contacted sporadically and asked for advice, but on the other hand most of the microbiologists think that this contact and discussion about the patient is reasonable and preferable. Of the respondents, 82.4% think that with a consequent interdisciplinary approach there might be lower antibiotic resistance rates in the future. One essential problem of ideal microbial diagnostics and therapeutic advice is that the microbiologist does not receive all relevant information upon request. This might be the case in up to 76.5%. Other problems are of economic nature or shortage of manpower. CONCLUSION: Interdisciplinary patient care between urologists and microbiologists is reasonable and preferable. This approach has the potential of decreasing antibiotic resistance rates in the future.

[Urogynaecological training situation in Germany : Gap between demand and reality]. / Urogynäkologische Aus- und Weiterbildungssituation in Deutschland : Kluft zwischen Anspruch und Realität.

BACKGROUND: With increasing life expectancy, progressive demographic change and decreasing societal stigmatization of incontinence urologists and gynaecologists are increasingly faced with urogynaecological challenges. To date however, urogynaecology is a poorly standardized area of expertise in both disciplines. Therefore, the urogynaecology training, especially in Germany, is very heterogeneous and requires evaluation as well as improvement. MATERIALS AND METHODS: The GeSRU-Academics research group "Functional urology and LUTS" evaluated this subject nationwide among urological and gynecological trainees and their chief physicians by using a comprehensive questionnaire (34/38 multiple-choice items) between April 2015 and May 2016. RESULTS: 336 urological residents and 190 chief physicians as well as 171 gynaecological residents and 175 chief physicians participated in the survey. Of all trainees, 70.0 % stated a personal interest in urogynaecology, but 45.4 % (gynaecological residents) and 52.9 % (urological residents) mention not to receive a standardized training in their own department. The chief physicians' survey resulted in discrepancies concerning the same question, <10 % of all residents do not receive a standardized urogynaecological training from their point of view. However, standardized urogynaecological training is of importance for those chief physicians. CONCLUSIONS: There is a discrepancy between expectations and reality of urogynaecological education and training. To enable a well-structured and standardized urogynaecological education and training, it is compulsory to focus on an interdisciplinary cooperation and to promote multidisciplinary development. A broad-based, well-designed training network and curricula should be established and used consistently.

Influence of surgeon's experience on fluoroscopy time during endourological interventions.

INTRODUCTION AND OBJECTIVE: Fluoroscopy time influences radiation exposure of both surgeons and patients during endourological interventions. Changes in fluoroscopy habits of endourological surgeons after being informed about their fluoroscopy times were evaluated depending on their endourological experience. MATERIALS AND METHODS: From April 2010 to April 2011, 402 endourological interventions in 337 Patients were assessed. Evaluated interventions were ureter stent placement (USP), ureter stent change (USC) nephrostomy change (NC), ureterorenoscopy (URS) and percutaneous nephrolithotomy (PCNL). Fluoroscopy time (FT) and operation time (OT) were recorded. For USP, USC and NC, the surgeons were divided into two groups: group I with >2 years of endourological experience and group II with <2 years experience. URS and PCNL only were performed by experienced surgeons. After 6 months, all surgeons were informed about their mean detected results. Both groups were compared, and changes in FT and OT in the second part of the study were analysed. RESULTS: Surgeons reduced their median fluoroscopy times up to 55 % after being informed about their fluoroscopy manners. Experienced surgeons reduced both operation and fluoroscopy times significantly for USP, USC and NC. For URS and PCNL, and OT and FT, the differences were not statistically significant. Inexperienced surgeons were not able to reduce both OT and FT significantly. CONCLUSION: If experienced surgeons are informed about their fluoroscopy time during endourological interventions, fluoroscopy times can be reduced significantly in easy procedures, which leads to less radiation exposure of surgeons and patients. Inexperienced surgeons have less possibility to influence their fluoroscopy manners.

[The impact of ultrasound in urology]. / Stellenwert des Ultraschalls in der Urologie.

Ultrasound is of great importance in the diagnosis of acute and chronic diseases in urology, such as kidney colic, testicular torsion, low-grade kidney trauma or for follow-up of vesicoureteral reflux, evaluation of infertility, measurement of residual urinary volume and the detection of cancer. An ultrasound examination is time and cost-effective without exposure to ionizing radiation and is routinely performed by practitioners as well as in the clinical daily routine. With technical innovations, such as contrast-enhanced ultrasound or real time elastography, it would for instance be possible to extend the application field of ultrasound. However, in some fields of investigation ultrasound still lacks accuracy and despite its many advantages the validity of ultrasound findings sometimes has to be verified with computed tomography (CT) or magnetic resonance imaging (MRI).

[Imaging diagnostics of the prostate]. / Bildgebung der Prostata.

Prostate cancer is the most common malignancy of men with approximately 32,000 new cases of prostate cancer in Germany and approximately 11,000 men who would die of the disease each year. For early diagnosis of prostate cancer PSA testing is used, whereas at present screening cannot be recommended due to the lack of confirmed medical and economic benefits. Regarding the imaging modalities, ultrasound of the prostate, currently performed in combination with elastography and histoscanning, magnetic resonance imaging of the prostate in combination with endorectal coils and positron emission tomography combined with computed tomography (PET-CT) are the methods of choice. Using these methods benign prostatitis can be differentiated from prostate cancer and staging of the tumor can be accomplished. On the other hand using these imaging methods it is possible to define the dominant intraprostatic lesion with different sensitivities and specificities, which is important for minimally invasive therapeutic strategies.

Upgrading of Gleason score 6 prostate cancers on biopsy after prostatectomy in the low and intermediate tPSA range.

When offering watchful waiting or active monitoring protocols to prostate cancer (PCa) patients, differentiation between Gleason scores (GS) 6 and 7 at biopsy is important. However, upgrading after prostatectomy is common. We investigated the impact of different PSA levels on misclassification in the PSA range of 2-3.9 and 4-10 ng ml(-1). A total of 448 patients with GS 6 PCa on prostate biopsy were evaluated by comparing biopsy and prostatectomy GS. Possible over diagnosis was defined as GS <7, pathological stage pT2a and negative surgical margins, and possible under diagnosis was defined as pT3a or greater, or positive surgical margins; the percentage of over- or under diagnosis was determined for correctly and upgraded tumors after prostatectomy. A match between biopsy and prostatectomy GS was found in 210 patients (46.9%). Patients in the PSA range of 2.0-3.9 and 4.0-10.0 ng ml(-1) were upgraded in 32.6 and 44.0%, respectively. Over diagnosis was more common than under diagnosis (23.2% vs 15.6%). When upgraded there was a significant increase in under diagnosis. As almost 40% of GS 6 tumors on biopsy are GS 7 or higher after surgery with a significant rise in under diagnosis there is a risk of misclassification and subsequent delayed or even insufficient treatment, when relying on favorable biopsy GS.

Health-related quality of life in children with vesicoureteral reflux - impact of successful endoscopic therapy.

OBJECTIVES: Endoscopic therapy for vesicoureteral reflux (VUR) using dextranomer/hyaluronic acid (Dx/HA) has become increasingly popular, but the subjective impact of this therapy and subsequent reflux resolution on health-related quality of life (HRQoL) remains unclear. The aim of this study was to address this issue. MATERIALS AND METHODS: One hundred children (65 girls, 35 boys; mean age 4.46 years) cured of primary VUR by endoscopic treatment were retrospectively reviewed. The Glasgow children's benefit inventory (GCBI) - a validated, reproducible, post-interventional questionnaire consisting of four subscales - supplemented by sociodemographic and disease-specific questions was employed. The HRQoL benefit was calculated on a scale ranging from -100 (complete failure) to +100 (complete success) and correlated with supplementary data. RESULTS: Total response rate was 88%. Mean total GCBI score was 28.4+/-20.3 representing a significant HRQoL amelioration. All GCBI subscores improved with the physical health subscale being most relevant. A gender-specific, significant difference in relative GCBI scores was discovered. Correlation with critical life events and time since operation proved the positive effect on HRQoL to be durable. CONCLUSIONS: Resolution of primary VUR secondary to Dx/HA treatment significantly improves HRQoL. HRQoL is positively affected in many areas and not only in those directly associated with VUR. These improvements are not temporary, suggesting that successful Dx/HA therapy may be superior to medical management in terms of children's quality of life.

Extracellular microenvironment and cytokine profile of the ureterovesical junction in children with vesicoureteral reflux.

PURPOSE: Vesicoureteral reflux is caused by a defective valve mechanism of the ureterovesical junction. Previous studies have revealed structural and metabolic changes in the intravesical ureter, impairing its contractile properties. Smooth musculature and nerves are replaced by collagen, while matrix degrading enzymes are over expressed. We investigated the presence of regulating cytokines and the extracellular matrix composition to elucidate further the pathophysiology of vesicoureteral reflux. MATERIALS AND METHODS: Ureteral endings were obtained from 28 children during antireflux surgery, and 14 age matched autopsy specimens served as controls. Routine histological sections were immunostained for insulin-like growth factor-1, nerve growth factor, transforming growth factor-beta1, tumor necrosis factor-alpha and vascular endothelial growth factor. Smooth muscle staining was supplemented by tenascin C, tetranectin and fibronectin detection. Staining patterns were investigated using computer assisted, high power field magnification analyses. RESULTS: Tumor necrosis factor-alpha and transforming growth factor-beta1 were significantly more abundant in vesicoureteral reflux samples, whereas insulin-like growth factor-1, nerve growth factor and vascular endothelial growth factor were more prevalent in healthy controls. Fibronectin was intensely expressed in refluxing ureters, while it was scarce in healthy children. Tenascin C was notable within the urothelium of both groups. Only vesicoureteral reflux samples displayed tenascin C in the musculature and connective tissue. Tetranectin staining was only detected in vesicoureteral reflux. CONCLUSIONS: Several cytokines are differentially expressed in primary refluxing ureters, indicating an ongoing tissue remodeling process in the ureterovesical junction region. Additionally, the smooth muscle coat is widely lacking, while extracellular matrix proteins typical for tissue shrinkage and reorganization are over expressed. These alterations are likely to contribute to the malfunctioning active ureteral valve mechanism in primary vesicoureteral reflux.
