Prospective evaluation of the RT-PCR based urinary marker Bladder Epicheck® as a diagnostic tool in upper urinary tract tumor.

BACKGROUND: Upper-tract-urothelial-carcinoma (UTUC) represents 5-10% of all urothelial-neoplasms with increasing incidence in the last decades. Current standard tools for diagnosis of UTUC include cytology, computed tomography (CT) urography and ureterorenoscopy (URS). The aim of this study was to evaluate the impact of Bladder Epicheck® Test as diagnostic tool for UTUC diagnosis and recurrence. METHODS: Overall, 136 urine samples, selective collected from upper-urinary-tract before URS for suspicion of UTUC were analyzed with cytology and Bladder Epicheck® Test. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of both markers were calculated and compared to URS and/or histology as reference. RESULTS: UTUC was detected in 40 cases (33.3%), among them 30 were classified as low-grade (LG) and 10 as high-grade (HG). Overall sensitivity of Bladder Epicheck® for UTUC detection was 65% compared to 42.5% for cytology, increasing to 100% for Bladder Epicheck® and 90% for cytology if considering only HG tumors. Overall specificity of Bladder Epicheck® was 81.2% and of cytology 93.7%. PPV and NPV were 63.4% and 82.2% for Bladder Epicheck® and 77.2% and 76.5% for cytology. Considering an EpiScore cut-off >75, instead of 60, specificity of Bladder Epicheck® improves to 89% and PPV to 74.2%. Limitations include the use of a marker validated only for bladder-cancer and the relatively small number of cases. CONCLUSIONS: Due to its high sensitivity for HG tumors, the Bladder Epicheck® Test can be used in diagnosis and treatment decision-making of UTUC. Furthermore, it could be very useful in follow-up of UTUC, after endoscopic treatment to postpone or avoid unnecessary endoscopic exploration. Even if further studies are needed to validate these findings, Bladder Epicheck® could be a promising clinical tool for detection of UTUC.

[New Sk2 guideline idiopathic posterior urethritis : Discussion of the current guideline using a case study]. / Neue Sk2-Leitlinie Urethritis posterior : Diskussion der aktuellen neuen Leitlinie anhand eines Fallbeispiels.

Posterior urethritis is diagnosed in prepubertal or pubertal boys mainly with terminal asymptomatic haematuria or postmicturition blood spotting on the meatus or in the underwear. It presents with typical changes in the bulbar urethra (hyperaemia, oedema and denuded mucosa) without laboratory or radiological findings. The pathology is self-limiting with a very good prognosis. This condition is most likely caused by dysfunctional voiding and urotherapy with biofeedback therapy offers good treatment results. Although urethrocystoscopy is the only way to confirm the diagnosis, the patient should be prevented from having a (usually unnecessary) urethrocystoscopy and the relatives should be reassured.

Treatment of long ureteric strictures with a free peritoneal graft: long-term results.

ZIEL DER STUDIE: Beschreibung einer neuen Technik zur Rekonstruktion von komplexen Ureterstrikturen unter Verwendung eines freien Peritoneallappens. MATERIAL UND METHODEN: Zwischen 2006 und 2021 behandelten wir 11 Patienten mit langen komplexen Harnleiterstrikturen, die in 9 Fällen den mittleren- und in 2 Fällen den proximalen Harnleiter betrafen. Die Länge der Strikturen variierte von 3 bis 12 cm (Mittelwert 7 cm). In drei Fällen handelte es sich um eine retroperitoneale Fibrose nach einem gefäßchirurgischen Eingriff, in zwei Fällen um einen Morbus Ormond, in vier Fällen um eine ausgedehnte Resektion großer Harnleitertumoren, in drei Fällen um wiederholte endoskopische Eingriffe bei Harnsteinen und in einem Fall um eine viermal fehlgeschlagene Pyeloplastik. Der Harnleiter wurde längs gespalten, ein freier Peritoneallappen aus dem nahe gelegenen gesunden Bauchfell entnommen und nach Positionierung eines Harnleiterkatheters als Onlay-Patch mit einer fortlaufenden Naht an der verbleibenden Harnleiterplatte fixiert. Der Ureter wurde zuletzt mit Omentum gedeckt. ERGEBNISSE: Die Nachbeobachtungszeit reichte von 12 bis 122 (Mittelwert 61,6) Monate. Sieben Patienten waren nach 12, 18, 60, 78, 98, 99 und 122 Monaten (Mittelwert 69,5 Monate) rezidivfrei, ohne Erweiterung des oberen Harntrakts und mit normaler Nierenfunktion. Bei vier Patienten kam es zu einem Rezidiv: Bei einem Patienten wurde das Rezidiv nach 60 Monaten ohne Symptome und mit leichter Hydronephrose festgestellt, ohne dass eine Operation erforderlich war. Bei einem Patienten mit Morbus Ormond trat das Rezidiv 6 Monate nach dem Eingriff symptomlos im distalen Teil des 10 cm langen Omlays auf. Es wurde eine Resektion des stenotischen Segments mit Psoas-Hitch durchgeführt. Bei den beiden anderen Patienten trat 3 und 6 Monate nach dem Eingriff eine Obstruktion unterhalb des rekonstruierten Segments mit Hydronephrose auf, ohne dass die Nierenfunktion beeinträchtigt war. Bei diesen Patienten wurde keine weitere Operation durchgeführt. Die Limitation dieser Studie besteht in der kleinen Studiengröße, die auf die strenge Indikationsstellung zurückzuführen ist. SCHLUSSFOLGERUNGEN: Die beschriebene Technik ermöglicht den Erhalt der verbleibenden Gefäßversorgung des Harnleiters und stellt eine praktikable und nützliche Alternative zu Nephrektomie, Ileum-Ureter, Uretero-Uretero-Stomie und Autotransplantation in hochselektierten Fällen dar.

[Evading the catastrophy]. / An der Katastrophe vorbei.

A 21-year-old athletic woman had been suffering from flank pain during fluid intake after sports for some time. Urological work-up revealed hydronephrosis with a "fishhook" shape and medial displacement of the ureter. This ureteral narrowing was studied ureterorenoscopically, bioptically and endoscopic-radiologically without the correct diagnosis of a retrocaval ureter being made. Therapeutically, a DJ stent was inserted several times, a balloon dilatation was performed under anaesthesia three times and finally a permanent DJ catheter was inserted. Due to the patient's dissatisfaction, an endoscopic endopyelotomy using Acucise was offered.

Transarterial Embolization in the Management of Intractable Haemorrhage.

INTRODUCTION: The purpose of this study was to evaluate the effectiveness and long-term results of selective transarterial iliac embolization (STIE) in patients with intractable bladder haemorrhage (IBH). METHODS: Twenty-five patients with a median age of 84 (range 65-94) years underwent STIE because of IBH between 2002 and 2020. The median follow-up time was 3 (mean 13.9) months. Patients were treated because of bleeding bladder or prostate cancer, radiation-induced haemorrhagic cystitis, and other conditions. Success was defined as technical success (feasibility to embolize bilateral hypogastric arteries or neoplastic arteries) and as clinical success (absence of further or additional therapy). RESULTS: Twenty-five patients with a median age of 84 years with a median hospital stay of 7 days were embolized at our institution. In total, 60% required additional therapy. Only 20% had minor complications, but no complication major was seen; 60% needed an additional therapy because of continuous bleeding. Our 30-day, 90-day, 6-month, and 12-month mortality rates were 28, 44, 64, and 76%, respectively. CONCLUSIONS: STIE in IBH is a safe, well-tolerated, and feasible procedure for palliating haematuria patients in poor general condition. Major complications are very rarely seen. However, patients often need additional therapy after STIE.

Do Health Professionals Sufficiently Address Patients' Disposition Toward Changing Their Nutritional and Physical Activity Habits? Findings from a Pilot Study among People with Type 2 Diabetes in Northern Italy.

The aim of our study was to evaluate the disposition of individuals with type 2 diabetes mellitus (DM2) toward changing their nutritional and physical activity habits and associated factors-particularly their perceptions about interacting and communicating with four health professions. Working with a local patients' association, we invited 364 individuals with DM2, all at least 18 years old, to complete a paper-based survey with questions addressing their experiences of interacting and communicating with general practitioners, nurses, dieticians and diabetologists and about their readiness to change targeted habits, their health literacy and their clinical status. Of the 109 questionnaires collected, 100 were eligible for descriptive and inferential statistical analysis. Regarding nutritional habits, the highest percentage of participants were at the maintenance stage (26%), whereas regarding physical activity habits the highest percentage of participants were at the preparation stage (31%). Significant differences between the habits emerged for four of the five stages and for two psychological processes. The precontemplation stage was most associated with communication-related variables, whereas the maintenance stage was associated with higher health literacy for both habits, and waist-to-height ratio was associated with several stages of change and psychological processes for physical activity habits. Considering aggregated stages (i.e., active or passive stage), significant differences were observed for all psychological processes except readiness to change nutritional habits. Logistic regression analysis revealed associations of the active stage with higher self-efficacy and lower discrepancy processes for both habits. Nutritional habits were associated with normal HbA1c values and physical activity habits with high cholesterol. Understanding the combination of the stages of change and how they relate to psychological processes can afford meaningful insights into the potential internal and external communication skills of health professions and should be examined as possible elements for a patient evaluation model.

Living on the Own Island? Aligned Collaboration Between Family Physicians, Nurses, Dieticians, and Patients With Diabetes Type 2 in an Outpatient Care Setting in Northern Italy: Findings From a Qualitative Study.

INTRODUCTION: Diabetes mellitus type 2 (DM2), one of the four most important chronic diseases worldwide, is generally considered to be preventable. However, it is not yet sufficiently clear whether an aligned collaboration between different health professions could facilitate behavioral changes to be made by patients with DM2 regarding their eating and physical activity habits. OBJECTIVE: To explore if and how far in current outpatient care for 3 health-care professions it is an objective to collaborate with each other supporting patients with DM2 in changing their eating and physical activity habits. METHODS: We conducted 18 qualitative problem centered interviews with selected family physicians, nurses, dieticians working in outpatient setting and patients with DM2, transcribed verbatim, and analyzed with qualitative content analysis. RESULTS: Issues identified ranged from description and reflection of current health-care practice, strategies, and hindrances to cope with changes of eating and physical activity behaviors as well as for health-care practice regarding interprofessional collaboration and patient-centered care up to considerations about collaboration and patient centricity (for health professionals and patients to achieve goals) and changes and ideas of "ideal care practice". DISCUSSION: The included professional groups work predominantly for themselves. Collaboration currently only takes place when individually triggered and neither structured nor organized.

The association of cigarette smoking and pathological response to neoadjuvant platinum-based chemotherapy in patients undergoing treatment for urinary bladder cancer - A prospective European multicenter observational study of the EAU Young Academic Urologists (YAU) urothelial carcinoma working group.

OBJECTIVE: To prospectively study the impact of smoking on pathological response to neoadjuvant chemotherapy (NAC) in patients undergoing radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). MATERIALS & METHODS: We collected standard clinicopathological variables, including smoking status (never, former, current) in patients undergoing NAC and RC for UCB at 12 European tertiary care centers between 12/2013-12/2015. Clinicopathological variables were compared according to smoking status. Multivariable logistic regression models were built to assess the association of smoking status and a) complete (no residual disease), b) partial (residual, non-muscle invasive disease), c) no pathological response (residual muscle invasive or lymph node positive disease). Kaplan-Meier and Cox regression analyses were employed to study the impact of response to NAC on survival. RESULTS AND LIMITATIONS: Our final cohort consisted of 167 NAC patients with a median follow-up of 15 months (interquartile range (IQR) 9-26 months) of whom 48 (29%), 69 (41%), and 50 (30%) where never, former, and current smokers, respectively. Smoking was significantly associated with advanced age (p = 0.013), worse ECOG performance status (p = 0.049), and decreased pathological response to NAC (p = 0.045). On multivariable logistic regression analyses, former and current smoking status was significantly associated with lower odds of complete pathological response (odds ratio (OR) 0.37, 95% confidence interval (CI) 0.16-0.87, p = 0.023, and OR 0.34, 95% CI 0.13-0.85, p = 0.021), while current smoking status was significantly associated with a greater likelihood of no pathological response (OR 2.49, 95% CI 1.02-6.06, p = 0.045). Response to NAC was confirmed as powerful predictor of survival. CONCLUSIONS: Smoking status is adversely associated with pathological response to NAC. Smokers should be informed about these adverse effects, counseled regarding smoking cessation, and possibly be considered for immunotherpeutics as they may be more effective in smokers.

Discovery of Molecular DNA Methylation-Based Biomarkers through Genome-Wide Analysis of Response Patterns to BCG for Bladder Cancer.

BACKGROUND: Bacillus Calmette-Guérin (BCG) immunotherapy, the standard adjuvant intravesical therapy for some intermediate and most high-risk non-muscle invasive bladder cancers (NMIBCs), suffers from a heterogenous response rate. Molecular markers to help guide responses are scarce and currently not used in the clinical setting. METHODS: To identify novel biomarkers and pathways involved in response to BCG immunotherapy, we performed a genome-wide DNA methylation analysis of NMIBCs before BCG therapy. Genome-wide DNA methylation profiles of DNA isolated from tumors of 26 BCG responders and 27 failures were obtained using the Infinium MethylationEPIC BeadChip. RESULTS: Distinct DNA methylation patterns were found by genome-wide analysis in the two groups. Differentially methylated CpG sites were predominantly located in gene promoters and gene bodies associated with bacterial invasion of epithelial cells, chemokine signaling, endocytosis, and focal adhesion. In total, 40 genomic regions with a significant difference in methylation between responders and failures were detected. The differential methylation state of six of these regions, localized in the promoters of the genes GPR158, KLF8, C12orf42, WDR44, FLT1, and CHST11, were internally validated by bisulfite-sequencing. GPR158 promoter hypermethylation was the best predictor of BCG failure with an AUC of 0.809 (p-value < 0.001). CONCLUSIONS: Tumors from BCG responders and BCG failures harbor distinct DNA methylation profiles. Differentially methylated DNA regions were detected in genes related to pathways involved in bacterial invasion of cells or focal adhesion. We identified candidate DNA methylation biomarkers that may help to predict patient prognosis after external validation in larger, well-designed cohorts.

Elderly patients undergoing cystectomy, comparing preoperative American Society of Anesthesiology and Eastern Cooperative Oncology Group scores and operative approaches.

OBJECTIVE: To evaluate preoperative scoring systems and operative management and their relation to complications in patients older than 75 years undergoing cystectomy at two academic institutions. METHODS: In total, 212 patients aged 75-95 years with muscle invasive bladder cancer underwent cystectomy at the University of Utah and Central Hospital of Bolzano, Italy. The rates of Grade 3 Clavien-Dindo complications and above in radical cystectomy patients (n = 199) were compared using Eastern Cooperative Oncology Group Scores and American Society of Anesthesiologists Physical Status Classification. The rates of Grade 3 Clavien-Dindo complications and above were also compared by urinary diversion type. Logistic regression was used to control for source institution. RESULTS: In total, 199 cases were included in the primary analysis. Neither of the preoperative scoring systems were predictive for identification of radical cystectomy patients with ⩾Grade 3 Clavien-Dindo complications. In secondary analysis (n = 212, including partial cystectomy), none of the urinary diversion types associated with radical cystectomy had a significantly different rate of complications. However, partial cystectomy (n = 13) had a significantly lower rate of complications. CONCLUSION: Complication rates among elderly patients undergoing cystectomy for muscle invasive bladder cancer were very high. For patients who are approved for surgery after the history and physical exam, none of our objective metrics adequately predicted operative risk. A unique diversion procedure described by the Bolzano group, uretero-ureterocutaneostomy, had equivalent complication rates to the more common diversion procedures. It also appears based on outcomes in this cohort that partial cystectomy is a particularly favorable option within the elderly population in terms of perioperative morbidity.

Use and duration of antibiotic prophylaxis and the rate of urinary tract infection after radical cystectomy for bladder cancer: Results of a multicentric series.

OBJECTIVES: To assess the rate of urinary tract infection (UTI), the characteristics of the bacterial aetiological agents involved, the type and duration of antibiotics used, and the clinical risk factors of UTI in a multi-institutional cohort of patients who had undergone radical cystectomy (RC). PATIENTS AND METHODS: The pre- and postoperative characteristics of patients who had undergone open RC at 1 of 3 institutions between 2009 and 2015 were analyzed by means of the patient charts. Patients were classified according to the presence or absence of UTI. Analysis of the severity of UTI was based on the EAU/EAU Section of Infections in Urology (ESIU) classification system. The bacterial aetiological agents and their antibiotic susceptibility were also assessed. Factors predicting postoperative UTI were identified using univariable and multivariable logistic regression analysis. RESULTS: Of 217 patients, 42 (19.4%) had developed postoperative UTI, of whom 50% had urosepsis or uroseptic shock. Multivariable analysis showed continent urinary derivation as the only significant predictor of UTI with an odds ratio of 5.03 (95% confidence interval 2.12-11.9, P < 0.001). The duration of perioperative antibiotic prophylaxis was not associated with an increased risk of UTI. Enterococcus was the most commonly isolated bacteria (25.7%), but this species is not covered by the recommended antibiotic prophylaxis. CONCLUSION: Patients with continent urinary diversion after RC have a significantly higher risk of developing UTI. Prolonged perioperative administration of antibiotics does not seem to reduce the risk of UTI. Enterococcus as the most commonly isolated bacteria is not covered by most recommended antibiotic prophylaxis regimens. Therefore different antibiotic regimens should be considered for high-risk patients.
