[Safety and efficacy of en bloc vs. conventional transurethral resection of bladder tumors: a meta-analysis and systematic review]. / Sicherheit und Effizienz der en bloc vs. konventionellen transurethralen Resektion von Blasentumoren: eine Metaanalyse und systematic Review.

BACKGROUND: En bloc tumor resection of bladder tumors (ERBT) is a novel alternative procedure to conventional resection of bladder tumor (cTURBT), which might help to address common problems of the standard method, such as inadequate detrusor muscle in specimens, high re-resection rates and high recurrence rates. OBJECTIVE: To analyze current data on ERBT in efficacy and safety compared to cTURBT. DATA SOURCES: PubMed. STUDY SELECTION: Two independent authors identified trials based on keywords and inclusion criteria. A third author was consulted in case of discrepancies. Screening keywords: ERBT, en bloc transurethral resection of bladder tumor, TURBT en bloc. A meta-analysis of 13 studies was performed. The effect size was estimated based on odds ratios and mean differences including their corresponding two-sided 95% confidence intervals. DATA SYNTHESIS: The analyzed studies comprised a homogenous collective in terms of tumor size, tumor multiplicity and tumor stage. Operation time did not significantly differ between the methods. Differences were observed in hospitalization and catheterization time in favor of ERBT. Reported complications did not show clear differences. There was significantly more detrusor muscle in the specimens in the ERBT group. No significant differences were found in recurrence up to 2 years of follow-up. CONCLUSION: ERBT is a safe alternative to conventional TURBT with promising features regarding effective resection of detrusor muscle. More standardized data on recurrence rates, different resection modalities and resection margin results are needed.

[The working time load of specialists and senior physicians in German urology-a critical assessment]. / Die Arbeitszeitbelastung von Fach- und Oberärzten in der deutschen Urologie ­ eine Bestandsaufnahme.

BACKGROUND: The working and continued training conditions of assistant physicians in urology in Germany have already been analyzed. But what about senior urologists in Germany? Under which conditions do they have to work? As far as we know no published data currently exist which illuminate the conditions of this special urological professional group, therefore, the results of this survey are presented. OBJECTIVE: To survey and evaluate the current working conditions of certified and senior urologists in Germany as comprehensively as possible. MATERIAL AND METHODS: The working group of employed physicians of the Professional Association of German Urologists (BvDU) carried out a survey within the framework of the urological senior physician forum 2016 and on-line via the e­mail distributor of the German Society for Urology (DGU). The questions involved the workload, working conditions and satisfaction, overtime performed, working hours and opt out regulations. RESULTS: A total of 176 senior physicians participated in the survey of which 88% were male and 12% female. In Germany there are 1125 senior physicians. The average age of the responders was 44.9 years. In more than 80% of the participants the average weekly working hours were over 50 h and 70% signed an opt out regulation. An association between an increasing job dissatisfaction above a working week over 55 h and an average attendance in on-call service over 4 h could be established. The number of on-call services had no influence on job satisfaction. A total of 43% (70 out of 162) of the participants stated that overtime hours were regularly forfeited and 12% (20 out of 162) that all overtime hours were forfeited. Approximately 30% of senior physicians in German urology were dissatisfied with the current working conditions in the present form. CONCLUSION: Based on the acquired data, adaptation and improvements in the working conditions of senior urologists are necessary in order to maintain the attractiveness of the occupational image and leading positions in German urology.

[Urological infections and antibiotic management in geriatric patients]. / Urologische Infektionen und Antibiotikamanagement bei geriatrischen Patienten.

Both the demographic shift and progress in medicine are resulting in an increasingly longer life expectancy. It is presumed that a mean age of 90 years will be achieved within the next decade in many countries. Thus, geriatric medicine, which is committed to the specific needs of older, often frail and frequently comorbid patients, is becoming increasingly more important. The prevalence of infections of the genitourinary tract increases with age, simultaneously, a critical and conscious use of antibiotics is required in terms of antimicrobial treatment. The intention of the present review is to make the reader aware of the specific characteristics of urinary tract infections and asymptomatic bacteriuria in the older patient population in terms of epidemiology, spectrum of pathogens and resistance as well as the indications for and performance of antimicrobial treatment.

[Workload, job satisfaction, Work Time Act-what is urology doing?] / Arbeitsbelastung, Arbeitszufriedenheit, Arbeitszeitgesetz ­ was macht die Urologie?

Due to demographic changes, the proportion of people requiring urological treatment will continue to rise. In order to better address this development, we need a well-trained and motivated urological medical community. Not only is continued education in urology an integral part of this, but it must also be embedded into future-oriented, flexible work-hour models, taking into account the German Work Time Act. Thus, in order to obtain a better assessment of the current situation of urological physicians undergoing specialist training, work -hour models currently used in urological clinics must be evaluated. This should allow conclusions to be drawn to find future-oriented solutions in order to do justice to the Future Offensive-Urology in 2025. Transparency, openness, and cooperation should be top priority between the DGU (German Association for Urology) working groups active in this field and the working groups of the BvDU (German Professional Association for Urologists).

[Endoscopic enucleation of the prostate]. / Endoskopische Enukleation der Prostata.

The spectrum of surgical procedures for the minimally invasive treatment of benign prostatic hyperplasia (BPH) has significantly increased over the last two decades. The simple suprapubic prostatectomy (subtotal prostatectomy, SP) has largely lost relevance in current practice. On the other hand, transurethral resection of the prostate (TURP) has been further standardized and potentially made safer by the introduction of the bipolar technique and low-pressure systems.Transurethral (endoscopic) enucleation techniques (endoscopic enucleation of the prostate, EEP) are increasingly competing with the current gold standard TURP and are replacing SP for treatment of larger adenomas. This approach is especially related to the rapid development of laser technology, which has sustainably changed the face of modern BPH treatment in a similar way to stone therapy. This has been incorporated in the clinical patient management, clinical studies and standardization of numerous surgical techniques that are systematically described in this article. Additionally, efforts have also been made to use other energy sources, such as bipolar current in EEP. With respect to scientific objectivity, high-quality clinical trials are regularly published which further strengthen the position of EEP.

Comparison of adjustable male slings and artificial urinary sphincter in the treatment of male urinary incontinence: a retrospective analysis of patient selection and postoperative continence status.

PURPOSE: To analyze and compare preoperative patient characteristics and postoperative results in men with stress urinary incontinence (SUI) selected for an adjustable male sling system or an artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. METHODS: 658 male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in this study (n = 176 adjustable male sling; n = 482 AUS). Preoperative patient characteristics and postoperative outcomes were analyzed. For statistical analysis, the independent T test and Mann-Whitney U test were used. RESULTS: Patients undergoing adjustable male sling implantation were less likely to have a neurological disease (4.5% vs. 8.9%, p = 0.021), a history of urethral stricture (21.6% vs. 33.8%, p = 0.024) or a radiation therapy (22.7% vs. 29.9%, p = 0.020) compared to patients that underwent AUS implantation. Mean pad usage per day (6.87 vs. 5.82; p < 0.00) and the ratio of patients with a prior incontinence surgery were higher in patients selected for an AUS implantation (36.7% vs. 22.7%; p < 0.001). At maximum follow-up, patients that underwent an AUS implantation had a significantly lower mean pad usage during daytime (p < 0.001) and nighttime (p = 0.018). Furthermore, the patients' perception of their continence status was better with a subjective complete dry rate of 57.3% vs. 22.0% (p < 0.001). CONCLUSIONS: Patients selected for an AUS implantation showed a more complex prior history and pathogenesis of urinary incontinence as well as a more severe grade of SUI. Postoperative results reflect a better continence status after AUS implantation, favoring the AUS despite the more complicated patient cohort.

[Extracorporeal shock wave lithotripsy]. / Extrakorporale Stoßwellenlithotripsie.

Interventional treatment of stones essentially consists of three treatment modalities. Extracorporeal shockwave lithotripsy (ESWL), in addition to uterorenoscopy (URS) and percutaneous nephrolitholapaxy (PCNL) is an essential treatment pillar and is the only noninvasive therapy option for the treatment of urinary stones. After a long period of ESWL being the leading choice in stone treatment, the number of SWL interventions diminished in recent years in favor of the other two treatment modalities (URS and PCNL). This article describes the indications, surgical technique and management of complications of SWL.

[Surgical positioning techniques in urology : Tips and tricks]. / Lagerungstechniken in der Urologie : Tipps und Tricks.

Correct positioning of patients during preoperative preparations is essential for success of the intervention to avoid any positioning trauma and to provide the best access to the targeted structures. The appropriate positioning (and optimal performance) means that complications are avoided and also makes an essential contribution to the smooth course of the surgical intervention. A correct position is essential particularly in urology because the organs assigned to the discipline of urology are anatomically mostly difficult to reach. A further important function of the correct positioning technique is the avoidance of injuries to the patient. This article summarizes the most common positioning techniques in urological interventions with special emphasis on the explanation of practical advice, helpful tips and possible complications that can enable even junior surgeons to correctly perform the appropriate positioning technique.

[Ureterorenoscopy]. / Ureterorenoskopie.

Ureterorenoscopy (URS) is a minimally invasive treatment option for removal of kidney stones, which has gained importance in this field over the past two decades. This technique has replaced extracorporeal shock wave lithotripsy (ESWL) stone surgery for many indications. It is also particularly important in the diagnostics and treatment for tumors of the upper urinary tract. This article describes the indications, surgical technique and management of complications of URS.

[Operative technique for percutaneous nephrolithotomy]. / Operative Technik der perkutanen Steintherapie.

Percutaneous nephrolithotomy (PCNL) is a well-established minimally invasive treatment option for removal of kidney stones. This technique has now replaced open stone surgery for virtually all indications. This article describes the indications, the surgical technique and the complication management of PCNL.

[Rare retrovesical tumor manifestation of cystic echinococcosis (Echinococcus granulosus)]. / Seltene retrovesikale Tumormanifestation der zystischen Echinokokkose (Echinococcus granulosus).

Unclear pelvic retrovesical intraperitoneal tumors can be caused by cystic echinococcosis. A definitive diagnosis of this disease is highly problematic und often requires a qualified histological/parasitological assessment. It is not possible to diagnose or exclude a cystic echinococcosis purely on the basis of a serological diagnosis. A multiple organ infection can be excluded using CT diagnostics as described in this case. The Robert Koch Institute has to be notified in the case of a positive result.

[Actinomycosis of the kidney: a case report]. / Aktinomykose der Niere: Ein Fallbericht.

Actinomycosis is a rare infection mainly of the head and neck region (cervicofacial actinomycosis). The cause of this infection is bacterial invasion of the host's mucosal barrier with consecutive infiltration of the surrounding tissues. The treatment of choice after diagnosis is a prolonged course of high-dose antibiotics. The presence of abdominal actinomycosis is at a maximum of 25%, whereas renal involvement appears only sporadically. Aggravating causes for early diagnosis are the appearance of abscesses, fistulae and a debilitating illness resembling carcinoma and leading to surgery as the treatment of choice. Renal actinomycosis is a diagnostic challenge because it is included in the differential diagnosis of renal masses with coexisting B-symptoms. The suspicion requires surgical treatment--nephrectomy. We report on a patient who was transferred to our department for nephrectomy because of radiologically diagnosed renal and perirenal abscesses. The histological result showed renal actinomycosis.
