Abstract
BACKGROUND In the context of blunt abdominal trauma, injuries to the urinary tracts often occur, especially in polytrauma patients. Urotrauma is rarely immediately life-threatening but can lead to serious complications and chronic functional limitations during treatment. Therefore early urological involvement is crucial for adequate interdisciplinary treatment. METHODS The most important facts for the clinical routine on the consultant urological management of urogenital injuries in blunt abdominal trauma are discussed according to the European "EAU guidelines on Urological Trauma" and the German "S3 guidelines on Polytrauma/Treatment of Severely Injured Patients" as well as the relevant literature. RESULTS Urinary tract injuries can occur even with an initially inconspicuous status and always require explicit exclusion diagnostics by means of contrast medium tomography of the entire urinary tract and, if necessary, by means of urographic and endoscopic examinations. The most common urological intervention is catheterization of the urinary tract which is often required. Less common is urological surgery, which should be coordinated interdisciplinarily with visceral and trauma surgery. More than 90% of vitally threatening kidney injuries (usually up to the American Association for the Surgery of Trauma (AAST) grades 4-5) are now treated by interventional radiology. CONCLUSION Due to possible complex injury patterns in blunt abdominal trauma, these patients should ideally be directed to (certified) trauma centers with subspecialized or maximum care from the departments of visceral and vascular surgery, trauma surgery, interventional radiology and urology.

Abstract
PURPOSE The aim of this study was to assess the post biopsy infection rate, feasibility and prostate cancer (PCa) detection rate (CDR) by performing transperineal MRI-TRUS fusion biopsy of the prostate (TPBx) under local anesthesia (LA) without antibiotic prophylaxis (AP). METHODS We prospectively screened 766 men with suspicious lesions on mpMRI, an elevated PSA level or a suspect digital examination undergoing MRI-TRUS-TPBx in LA, from May 2019 to July 2020. Patients with the need for antibiotic prophylaxis or without a PI-RADS target lesion were excluded from final analyses. We reported CDR, perioperative pain (0-10) and postoperative complications. PCa with an ISUP grade ≥ 2 was classified as clinically significant PCa (csPCa). RESULTS We included 621 patients with a median age of 68 years (IQR 62-74), a PSA of 6.43 ng/mL (IQR 4.72-9.91) and a prostate volume of 45 cc (IQR 32-64). In median, 4 targeted (TB) (IQR 3-4) and 6 (IQR 5-7) systematic biopsies (SB) detected in combination overall 416 (67%) PCa and 324 (52%) csPCa. Overall CDR of TB for PI-RADS 3, 4 and 5 was 26%, 65% and 84%, respectively. Patients reported a median perioperative pain level of 2 (IQR 1-3). Four patients (0.6%) developed a post biopsy infection, one experienced urosepsis. CONCLUSION Our results demonstrate that transperineal MRI-TRUS fusion-guided prostate biopsy under LA without AP is feasible, safe and well tolerated.

Abstract
The aim of this study was to assess the germination, survival and metabolic activity of the probiotic Bacillus coagulans GBI-30, 6086 [GanedenBC30] (BC30) in a dynamic, computer controlled in vitro model of the gastrointestinal (GI) tract, simulating human adults. Experiments were performed in the presence of a meal to maximise germination, due to the presence of germination-triggers. Both an upper GI tract (stomach and small intestine; TIM-1) and a colon model (TIM-2) were used, where material exiting TIM-1 was added to TIM-2. Spores of BC30 were introduced in the gastric compartment of TIM-1 and samples were taken immediately after the pylorus. Moreover, for 6 h, every hour the ileal efflux was collected and a subsample was plated for viable counts (spores and germinated cells). The remainder of the sample was fed to TIM-2, and after 24 h another sample was taken and tested for viable counts. In addition, samples were taken from the dialysates of the model and analysed using LC-MS/MS to determine bacterial metabolites and digestion products. Survival after transit through the gastric compartment was high (97%) and most cells were still in the spore form (76%). Survival after transit through TIM-1 was on average 51%, meaning that on average half of the orally provided spores was found back as cfu on the agar plates. Of these on average 93% were germinated cells and only 7% were spores. 24 h after the start of the experiments germination had increased in TIM-2 to 97% vegetative cells, and only 3% spores. No further loss of viability was observed in TIM-2. In terms of metabolic activity, increased levels of amino acids, dipeptides and citric acid cycle metabolites were found compared to experiments in the absence of BC30. In conclusion, BC30 spores germinate to a large extent (>90%) in the presence of germination triggers in the small intestine in a model that closely mimics the physiological conditions of human adults. Of the oral dose, as much as half of the cells survived transit through the upper GI tract, and based on the metabolite profile, these cells were metabolically active. Either these cells or the enzymes released from the dead cells aided in digestion of the meal. These insights help explain some of the observations in previous experiments, and support the understanding of the mechanism of action of the probiotic BC30.

Abstract
BACKGROUND Several systems for MRI/TRUS fusion-guided biopsy of the prostate are commercially available. Many studies have shown superiority of fusion systems for tumor detection and diagnostic quality compared to random biopsy. The benefit of fusion systems in focal therapy of prostate cancer (PC) is less clear. OBJECTIVES Critical considerations of fusion systems for planning and monitoring of focal therapy of PC were investigated. MATERIALS AND METHODS A systematic literature review of available fusion systems for the period 2013-5/2016 was performed. A checklist of technical details, suitability for special anatomic situations and suitability for focal therapy was established by the German working group for focal therapy (Arbeitskreis fokale und Mikrotherapie). RESULTS Eight fusion systems were considered (Artemis™, BioJet, BiopSee®, iSR´obot™ Mona Lisa, Hitachi HI-RVS, UroNav and Urostation®). Differences were found for biopsy mode (transrectal, perineal, both), fusion mode (elastic or rigid), navigation (image-based, electromagnetic sensor-based or mechanical sensor-based) and space requirements. DISCUSSION Several consensus groups recommend fusion systems for focal therapy. Useful features are "needle tracking" and compatibility between fusion system and treatment device (available for Artemis™, BiopSee® and Urostation® with Focal One®; BiopSee®, Hitachi HI-RVS with NanoKnife®; BioJet, BiopSee® with cryoablation, brachytherapy). CONCLUSIONS There are a few studies for treatment planning. However, studies on treatment monitoring after focal therapy are missing.

Abstract
The aim of this study was to assess the potential of the probiotic Bacillus coagulans GBI-30, 6086 [GanedenBC30] (BC30) to aid in protein digestion of alimentary plant proteins. To test this, three plant proteins, from pea, soy and rice, were digested in a validated in vitro model of the stomach and small intestine (TIM-1) in the absence and in the presence of BC30. Samples were taken from the TIM-1 fractions that mimic uptake of amino acids by the host and analysed for α-amino nitrogen (AAN) and total nitrogen (TN). Both were increased by BC30 for all three plant proteins sources. The ratio of TN/AAN indicated that for pea protein digestion was increased by BC30, but the degree of polymerisation of the liberated small peptides and free amino acids was not changed. For soy and rice, however, BC30 showed a 2-fold reduction in the TN/AAN ratio, indicating that the liberated digestion products formed during digestion in the presence of BC30 were shorter peptides and more free amino acids, than those liberated in the absence of BC30. As BC30 increased protein digestion and uptake in the upper gastrointestinal (GI) tract, it consequently also reduced the amount of protein that would be delivered to the colon, which could there be fermented into toxic metabolites by the gut microbiota. Thus, the enhanced protein digestion by BC30 showed a dual benefit: enhanced amino acid bioavailability from plant proteins in the upper GI tract, and a healthier environment in the colon.

Abstract
BACKGROUND A revised version of the PI-RADS scoring system has been introduced and score-related variability between version 1 and 2 may be suspected. This study aimed to assess the PI-RADS scores derived from version 1 (v1) and the updated version 2 (v2). MATERIAL AND METHODS 61 patients with biopsy-proven prostate cancer (PCa) and 90 lesions detected on pre-biopsy 3-Tesla multiparametric MRI were included in this retrospective analysis. 2 experienced radiologists scored all lesions in consensus. Lesion scores differing between PI-RADS v1 and v2 were further analyzed. Histology data from radical prostatectomy (RP) were included when available. RESULTS The PI-RADS v1 and v2 score differed in 52% of patients (32/61) and in 39% of lesions (35/90). On a lesion basis, the reason for the differences were related to sum score in v1 vs. categorical system in v2 in 51% (18/35) of lesions, cutoff between PI-RADS 4 and 5 based on lesion size in v2 as opposed to the sum score in v1 in 31% (11/35) and were inconclusive in 17% (6/35). The RP subgroup indicates enhanced detection of PCas with GS 3+3 and GS 3+4 in v2. CONCLUSION PI-RADS scores of prostatic lesions frequently differed between v1 and v2, the major reasons for these differences being score-related. In men undergoing RP, PI-RADS v2 improved detection of low risk PCa, but did not increase accuracy for discrimination of GS 3+4 vs. GS≥4+3 compared to v1. Urologists should be aware of the system-related differences when interpreting PI-RADS scores.

Abstract
Sertoli cell tumors are a rare malignancy which account for approximately 1.5 % of all testicular tumors. Although malignant Sertoli cell tumors are uncommon, they are associated with a poor prognosis. So far 36 cases of malignant courses of disease have been described. We present a patient with a lymphogenic metastasized Sertoli cell tumor, who 24 months after orchiectomy and extended retroperitoneal lymphadenectomy is relapse-free.

Abstract
BACKGROUND Magnetic resonance imaging (MRI)/ultrasound (US) fusion-guided biopsy detects more prostate cancer (PCa) than transrectal US (TRUS)-guided biopsy in patients with an indication for prostate re-biopsy. The aim of this study was a) to compare the detection rates of MRI/US fusion-guided biopsy with conventional TRUS in a double centre cohort and b) to investigate the influence of the number of pre-biopsies on the PCa detection rate. MATERIAL AND METHODS In the period from January 2012 to July 2014, 310 consecutive patients gave written informed consent and underwent 3 Tesla MRI scans of the prostate. All patients had at least one PCa suspicious lesion in the MRI and were biopsied by MRI/US fusion followed by a conventional 10-core biopsy of the prostate. Detection rates based on technique, Gleason score and number of pre-biopsies were calculated. RESULTS The overall detection rate of the study was 51% (158 patients). Among these 158 patients a histopathological Gleason score of 6 was detected in 60 patients (38%), a Gleason score of 7 in 54 patients (34%) and a Gleason score≥8 in 44 patients (28%). MRI/US fusion-guided biopsy detected 110 (69.7%) of the overall detected 158 PCa. TRUS-guided biopsy detected a higher rate of Gleason score 6 (54%) and a lower rate of Gleason score≥8 (15%) lesions in comparison to 38% Gleason 6 and 28% Gleason≥8 in the MRI/US fusion-guided biopsy, respectively. Furthermore, a lower Gleason score was observed in patients with more than one pre-biopsy. The detection rate in biopsy-naïve patients undergoing MRI/US fusion was 75% (40 patients) among 75% detected Gleason score≥7. CONCLUSION MRI/US fusion-guided biopsy detected more PCa and also more clinically significant cancer than conventional TRUS. In our cohort patients with more than one pre-biopsy showed lower Gleason scores. The included patients with an initial MRI/US fusion-guided biopsy should be further investigated.

Abstract
BACKGROUND According to the guidelines of the European Association of Urology (EAU) on prostate cancer (PCa) in 2013, patients with increasing prostate-specific antigen (PSA) levels, suspicious digital rectal examination (DRE) or high-grade prostatic intraepithelial neoplasia after negative prostate biopsy (PB) should undergo a repeat biopsy. Low cancer detection rates in the repeat biopsy illuminate the dilemma of the international gold standard of transrectal ultrasound (TRUS) guided PB in the detection of PCa. Our study evaluated the combination of TRUS and prostate magnetic resonance imaging (MRI) and its reported high sensitivities and high specificities by using real-time MRI/US fusion-guided biopsy. The detection of clinically significant PCa was investigated. MATERIAL AND METHODS 128 consecutive patients in the period of January 2012 to August 2013 were included. All patients had at least one TRUS-guided biopsy with negative findings and the clinical indication for a systematic re-biopsy. Prior to the MRI/US fusion all patients underwent a 3 Tesla prostate MRI without endorectal coil. The MRI data were uploaded to a modern US system. The B-mode, power-mode, elastography and CEUS imaging were used to classify the suspicious lesions from the MRI on a scale of 0-3 and a US sum score was calculated. The lesion was consecutively biopsied by real-time MRI/US fusion followed by a systematic 10 core biopsy. RESULTS Among 128 patients 51 PCa could be detected (39.8%). From these 51 PCa cases, clinically significant PCa was detected by MRI/US fusion-guided biopsy as follows: Gleason score >7 in 9 of 10 patients; Gleason score=7 in 14 of 20 patients and Gleason score <7 in 13 of 21 patients. A positive correlation was shown between the US sum score and the associated PI-RADS score in 65 patients in whom lesions were classified by PI-RADS. A positive correlation was further shown between the US sum score and the Gleason score of all suspicious and biopsied lesions. MRI/US fusion and TRUS-guided biopsy combined, detected 30 of 51 PCa; 6 of 51 PCa were detected by MRI/US fusion alone and 15 of 51 PCa by conventional TRUS-guided biopsy alone. CONCLUSION Real-time MR/US fusion increases detection rates of PCa in patients undergoing repeat biopsy. Especially, clinically significant PCa with a Gleason score ≥ 7 were almost exclusively detected by MR/US fusion-guided biopsy.

Abstract
BACKGROUND In elderly and multimorbid patients urosepsis is a particularly serious condition with a high mortality. Whether a secondary therapy for an underlying stone disease after -initial sepsis treatment improves the prognosis of these patients has not been systematically investigated. We retrospectively reviewed the clinical course of elderly and multimorbid patients with urosepsis regarding the frequency of rhospitalisation and sepsis recurrence after initial and subsequent therapy. PATIENTS AND METHODS Patients with and without urolithiasis and urosepsis were compared. Inclusion criteria were multimorbidity, defined by an ASA score (≥2) or a Charlson score (≥3) and age (≥60 years), and general sepsis features. Both groups (patients with urolithiasis [U+] and patients without urolithiasis [U-]) did not differ in terms of demographic data. We investigated the influence of the primary sepsis therapy and secondary stone treatment on the incidence of rehospitalisation and sepsis recurrence rate. RESULTS The incidence of rehospitalisation in stone patients (U+) with and without therapy did not differ (22.1% vs. 21%), while the occurrence of urosepsis was lower in treated patients (0% vs. 8.7%). Rehospitalisation in stone patients was generally less common than in patients without urolithiasis (U+ 21.6%, U- 44.4%). Recurrences of sepsis were higher in patients without stone disease (U+ 4.35%, U- 8.9%). If the subpopulation with successful stone therapy was extracted from the U+ group, the difference disappeared (U+ 8.7%, U- 8.9%). CONCLUSIONS Stone treatment after initial urosepsis therapy reduces the incidence of recurrent sepsis (0% vs. 8.7%). Patients without underlying urolithiasis (U-) have a similar risk of sepsis recurrence as urolithiasis patients without secondary stone treatment. A complete stone clearance should be pursued in multimorbid or elderly patients with urosepsis to reduce secondary morbidity.

Abstract
BACKGROUND In patients with low-risk prostate cancer (PCa) the standard therapies carry a risk of overtreatment with potentially preventable side effects whereas restrained therapeutic strategies pose a risk of underestimation of the individual cancer risk. Alternative treatment options include thermal ablation strategies such as high-intensity focused ultrasound (HIFU). PATIENTS AND METHODS 96 patients with low-risk PCa (D'Amico) were treated at 2 HIFU centres with different expertise (n=48, experienced centre Lyon/France; n=48 inexperienced centre Charité Berlin/Germany). Matched pairs were formed and analysed with regard to biochemical disease-free survival (BDFS) as well as postoperative functional parameters (micturition, erectile function). The matched pairs were discriminated as to whether they had received HIFU treatment alone or a combination of HIFU with transurethral resection of the prostate (TURP). Patients of the Lyon group were retrospectively matched through the @-registry database whereas patients of the Berlin group were prospectively evaluated. In the latter patients quality of life assessment was additionally inquired. RESULTS Postoperative PSA-Nadir was lower in the Berlin group for patients with HIFU only (0.007 vs. Lyon 0.34 ng/ml; p=0.037) and HIFU+TURP (0.25 vs. Lyon 0.42 ng/ml; p=0.003). BDFS was comparable in both groups for HIFU only (Berlin 4.77, Lyon 5.23 years; p=0.741) but patients with combined HIFU+TURP in the Berlin group showed an unfavourable BDFS as compared to the Lyon group (Berlin 3.02, Lyon 4.59 years; p=0.05). In an analysis of Berlin subgroups especially patients who had received HIFU and TURP (n=4) within the same narcosis had an unfavourable BDFS (p=0.009). Median follow-up was 3.36 years for HIFU only and 2.26 years for HIFU+TURP. Neither HIFU only (p=0.117) nor HIFU+TURP (p=0.131) showed an impact on postoperative micturition. Erectile function was negatively influenced (HIFU: p=0.04; HIFU+TURP: p=0.036). There was no measurable change in quality of life after the treatment. CONCLUSION The 4-year BDFS after HIFU and HIFU+TURP is comparable to that of the standard therapies. The erectile function is sustainably negatively influenced whereas postoperative micturition and quality of life were not affected by HIFU or HIFU+TURP. These results are strongly limited by the low patient count and the short follow-up period and require validation in prospective multicentre studies with higher number of cases.

Abstract
BACKGROUND Patients with (local) recurrence of prostate cancer after radiation therapy face the question of the appropriate diagnostic and possible therapeutic options. Many patients in this setting receive palliative androgen deprivation therapy alone, with arguable impact on overall cancer survival. In the case of an isolated local recurrence, salvage prostatectomy represents a potentially curative therapeutic option, albeit with a high complication rate. Alternatively, these patients can be offered a local treatment with salvage HIFU therapy. MATERIAL AND METHODS Salvage HIFU therapy is based on the thermal ablation of tissue through high-intensity focused ultrasound. In addition, the formation of microbubbles (cavitation) and their implosion lead to an enhancement of tissue ablation. RESULTS The results of 6 monocentric studies (2004-2011) with an overall number of 408 patients (22-167 patients) are presented and critically reviewed. The median follow-up was 18.71 months (7.4-39). The 3-year progression free survival (PFS) varied from 25% (D'Amico high risk) to 53% (D'Amico low-risk), the 5-year overall survival was 90%. The rate of urinary incontinence varied between 7 and 60% in all grades (grade III urinary incontinence 0-9.5%). In 22 cases surgical incontinence treatment was performed. 53 patients developed a urethral stricture or stenosis leading to surgical treatment. Urethral-rectal fistulae were seen in 0-7%. CONCLUSIONS The current data on salvage HIFU can be evaluated as insufficient. The main criticisms can be seen in the lack of randomization, the monocentric and retrospective analyses of the data, the heterogeneous stratification of risk groups as well as inadequate definition of postinterventional treatment failure. The studies indicate that salvage HIFU therapy leads to a mid-term overall survival with complication rates that are comparable to those of other local salvage therapies. Randomized multicentric studies are needed to further validate the results of salvage HIFU therapy.

Abstract
INTRODUCTION Extracorporeal shock wave lithotripsy (ESWL) has evolved as a standard treatment modality for calculi of the upper urinary tract. Noninvasive ESWL shows rare life-threatening complications. Herein we have reported the case of a liver transplant recipient who developed severe renal hemorrhage after ESWL of a renal calculus. Transfusion of erythrocytes and platelets led to anaphylactic shock with acute renal failure requiring intensive care. The patient fully recovered shortly thereafter and was discharged home with a residual left kidney stone measuring 8 mm. CASE PRESENTATION A 55-year-old man with a single left kidney underwent ESWL due to symptomatic left nephrolithiasis. He had undergone successful liver transplantation 11 years earlier. At the time of ESWL his liver functions were normal and his serum creatinine level was 1.3 mg/dL. Two weeks before the treatment a double pigtail ureteral stent was inserted because of a symptomatic left hydronephrosis. Several hours after ESWL treatment the patient complained of left-sided flank pain. An ultrasound revealed a large subcapsular hematoma of the left kidney, which was confirmed using abdominal computed tomography (CT). With the patient being hemodynamically stable, we opted for conservative management. Despite postinterventional complications, the patient made a fast recovery. CONCLUSION ESWL is a noninvasive, safe, and efficient method to treat renal calculi. Patients who are at risk for hemorrhage should undergo close postinterventional monitoring, including red blood cell count and renal ultrasound.

Abstract
A dose-ranging study with oral levonantradol was performed in 20 cancer patients. The optimum oral dose which attenuated vomiting accompanying chemotherapy was 1 mg 4-hourly. Side-effects comprised dizziness, confusion, euphoria, drowsiness, and difficulty in concentrating. There was no cardiovascular toxicity. Overall toxicity appeared to be dose-related and was mild and acceptable.
