The influence of socioeconomic status and gender on incidence and survival in bladder cancer: a longitudinal study based on the Hamburg Cancer Registry.

BACKGROUND: To investigate the influence of socioeconomic status (SES) and gender on the incidence and survival of patients with bladder cancer on a small scale within the city of Hamburg, Germany. METHODS: Patients documented in the Hamburg Cancer Registry aged ≥ 18 years with primary bladder carcinoma (ICD-10: C67, D09.0), diagnosed in the period 2004-2020 (follow-up until 31.12.2021), and residing in Hamburg were included. The patients were divided into three groups (low, intermediate, and high SES) based on the socioeconomic situation at the district level, defined by the proportion of unemployed individuals, social housing, benefit recipients according to law, etc. Relative survival in the years 2004-2020 was calculated using a period approach. RESULTS: Among the 10,659 patients included, age-standardized 5-year relative survival (5YRS) in 2004-2020 correlated with SES. The age-standardized 5YRS differed significantly between patients with high and intermediate SES vs low SES. Women with low SES had the worst 5YRS at 58.2%, while men with high SES presented the best relative 5YRS at 73.5%. This effect remained after stratification by UICC stages. Concerning incidence, there is an indication that women with low SES were more often diagnosed in higher UICC stages III or IV than women with high SES (18.3% versus 12.6%). CONCLUSIONS: The socioeconomic situation at the time of diagnosis, as well as gender, has a substantial impact on the incidence and cancer survival rates in patients with bladder cancer. Further research, including the study of patient care, is needed to better understand and address these inequalities.

[Lichen sclerosus in clinically relevant phimosis: incidence, risk factors, and association with squamous cell carcinoma of the penis]. / Lichen sclerosus bei klinisch relevanter Phimose: Häufigkeit, Risikofaktoren und Assoziation mit Plattenepithelkarzinomen des Penis.

BACKGROUND: Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory skin disease. It is frequently diagnosed following circumcision. Diabetes mellitus (DM) is a known risk factor in men. Malignant pathology is more common in patients with LSA. Data on LSA in men are very limited. OBJECTIVE: This study investigated the incidence of LSA in men who had undergone circumcision. Risk factors and likelihood of malignancy were captured. MATERIALS AND METHODS: Data of 215 patients were retrospectively analyzed. As potential risk factors, age, body mass index (BMI), DM, coronary heart disease (CHD) and arterial hypertension were identified. Data were analyzed and displayed graphically as spike histograms. Logistic regression was applied. Age and BMI were transformed using cubic spline function. RESULTS: Mean age of patients was 37 years (±â€¯22 years). Mean BMI was 26.4. In all, 24% of the patients had a BMI > 30. Of the patients, 11% had DM, 5.1% had CHD, and 19% had arterial hypertension. Pathology revealed LSA in 47% of patients. Malignant disease was apparent in 3.3% of patients (2.7% without concomitant LSA, 4% with concomitant LSA). Age (55 vs 20 years, odds ratio [OR]: 3.210 [1.421, 7.251]) was a significant risk factor for LSA. BMI (30 vs 22 kg/m2, OR 1.059 [0.614, 1.828]) and DM (OR: 0.42 [0.148, 1.192]) elevated the risk for LSA. CONCLUSION: We saw high rates of LSA in patients had undergone circumcision. Higher age represents a significant risk factor. In 3.3%, final pathology revealed squamous cell carcinoma of the penis. Therefore, pathologic work-up of circumcision specimen is mandatory.

Ultrasound imaging of male urethral stricture disease: a narrative review of the available evidence, focusing on selected prospective studies.

PURPOSE: To synthetize the current scientific knowledge on the use of ultrasound of the male urethra for evaluation of urethral stricture disease. This review aims to provide a detailed description of the technical aspects of ultrasonography, and provides some indications on clinical applications of it, based on the evidence available from the selected prospective studies. Advantages and limitations of the technique are also provided. METHODS: A comprehensive literature search was performed using the Medline and Cochrane databases on October 2022. The articles were searched using the keywords "sonourethrography", "urethral ultrasound", "urethral stricture" and "SUG". Only human studies and articles in English were included. Articles were screened by two reviewers (M.F. and K.M.). RESULTS: Our literature search reporting on the role of sonourethrography in evaluating urethral strictures resulted in selection of 17 studies, all prospective, even if of limited quality due to the small patients' number (varied from 28 to 113). Nine studies included patients with urethral stricture located in anterior urethra and eight studies included patients regardless of the stricture location. Final analysis was based on selected prospective studies, whose power was limited by the small patients' groups. CONCLUSION: Sonourethrography is a cost-effective and safe technique allowing for a dynamic and three-dimensional urethra assessment. Yet, because of its limited value in detecting posterior urethral strictures, the standard urethrography should remain the basic 'road-map' prior to surgery. It is an operator-dependent technique, which can provide detailed information on the length, location, and extent of spongiofibrosis without risks of exposure to ionizing radiation.

[Evaluation and management of urethral strictures-guideline summary 2024 : Part 2-posterior urethra]. / Diagnostik und Therapie von Harnröhrenstrikturen ­ Leitlinienübersicht 2024 : Teil 2 ­ posteriore Harnröhre.

In light of recently published international guidelines concerning the diagnosis, treatment, and aftercare of urethral strictures and stenoses, the objective of this study was to synthesize an overview of guideline recommendations provided by the American Urological Association (AUA, 2023), the Société Internationale d'Urologie (SIU, 2010), and the European Association of Urology (EAU, 2023). The recommendations offered by these three associations, as well as the guidelines addressing urethral trauma from the EAU, AUA, and the Urological Society of India (USI), were assessed in terms of their guidance on posterior urethral stenosis. On the whole, the recommendations from the various guidelines exhibit considerable alignment. However, SIU and EAU place a stronger emphasis on the role of repeated endoscopic treatment compared to AUA. The preferred approach for managing radiation-induced bulbomembranous stenosis remains a subject of debate. Furthermore, endoscopic treatments enhanced with intralesional therapies may potentially serve as a significant treatment modality for addressing even fully obliterated stenoses.

[Evaluation and management of urethral strictures-guideline summary 2024 : part 1-anterior urethra]. / Diagnostik und Therapie von Harnröhrenstrikturen ­ Leitlinienübersicht 2024 : Teil 1 ­ anteriore Harnröhre.

In recent years, several international urological societies have published guidelines on the diagnosis, treatment, and follow-up of urethral strictures, but a guideline for the German-speaking region has not been available to date. This summary provides a detailed comparison of the guidelines of the European Association of Urology (EAU), American Urological Association (AUA) and the Société Internationale d'Urologie (SIU) with regard to the treatment of anterior urethral strictures, i.e. from the bulbar urethra to the meatus. In the following work, differences and specific recommendations in the guidelines are highlighted. In particular, the three guidelines largely agree with regard to diagnostic workup and follow-up. However, divergences exist in the management of anterior urethral strictures, particularly with regard to the use of endoscopic therapeutic approaches and the use of urethral stents. In addition, the EAU provides more comprehensive and detailed recommendations on urethroplasty techniques and specific patient follow-up. The EAU guidelines are the most current and were the first to include instructions for urethral strictures in women and individuals with gender incongruence after genital approximation surgery. Reconstructive urology is a rapidly evolving specialty and, thus, the clinical approach has been changing accordingly. Although guideline recommendations have become more inclusive and comprehensive, more high-quality data are needed to further improve the level of evidence.

[Urinary diversion with or without simple cystectomy as a salvage option for benign diseases of the lower urinary tract]. / Harnableitungen mit oder ohne simple Zystektomie in der Salvage-Therapie benigner Erkrankungen des unteren Harntraktes.

Benign diseases of the lower urinary tract can occur as a result of oncological or neurological diseases or their respective therapies (e.g., surgery or radiation treatment) and can significantly reduce the quality of life for affected patients. Urinary diversion serves as a salvage option when all other therapeutic regimens have been carried out and proven unsuccessful. When selecting the suitable urinary diversion, a comprehensive clinical assessment of the patients is required in order to ensure long-term success. In some cases, a cutaneous, catheterizable pouch offers the last and only option for a long-term and definitive treatment of a patient's condition. Overall, a decreasing trend in the establishment of a continent urinary diversion is observed in Germany. Current data on benign indications for urinary diversion are limited. Therefore, further data collection and research are needed.

Treatment Success After Urethroplasty: The Ongoing Quest for a Pragmatic and Universal Definition.

There is no consensus on the ideal definition of success after urethroplasty, which makes research, quality control, and comparisons challenging. Ongoing research endeavors are focused on achieving consensus regarding the optimal battery of outcomes for evaluation of patients after urethroplasty.

Urethral management after artificial urinary sphincter explantation due to cuff erosion.

Introduction: The artificial urethral sphincter (AUS) is the gold standard treatment in cases of moderate-to-severe stress urinary incontinence in males. Cuff erosions are one of the most important distant complications of AUS implantation. The optimal urethral management has still not been established. Material and methods: Search terms related to 'urethral stricture', 'artificial urinary sphincter', and 'cuff erosion' were used in the PubMed database to identify relevant articles. Results: In this mini review we identified 6 original articles that assessed the urethral management after AUS explantation due to cuff erosion and included urinary diversion by transurethral and/or suprapubic catheterization, urethrorrhaphy, and in situ urethroplasty. We summarized the results of different management methods and their efficacy in terms of preventing urethral stricture formation. We highlight the need for better-quality evidence on this topic. Conclusions: The available data do not provide a clear answer to the question of optimal urethral management during AUS explantation. There is a great need to provide higher-quality evidence on this topic.

Reaching Consensus for Comprehensive Outcome Measurement After Urethral Stricture Surgery: Development of Study Protocol for Stricture-Fecta Criteria.

Urethral stricture disease is a very heterogeneous condition where different urethral segments can be involved as a result of diverse etiologies which come with variable prognosis. The surgical management of urethral strictures, and in particular urethroplasties can result in very diverse outcomes on many levels and, currently, there is absolutely no consensus about what should and what should not be considered a "success" after urethral surgery. In the wake of well-established quality criteria in urologic oncology, such as tri- or pentafecta outcomes, and given the lack of agreement on meaningful outcomes after urethral surgery, we aim to introduce our study protocol as the first step of a multistep research endeavor to reach consensus on comprehensive urethroplasty outcomes within a novel conceptual framework: the "stricture-fecta criteria". The development of stricture-fecta will be based on a Delphi consensus involving some of worldwide most influencing reconstructive urologists.

Contemporary Outcomes after Transurethral Procedures for Bladder Neck Contracture Following Endoscopic Treatment of Benign Prostatic Hyperplasia.

OBJECTIVES: Bladder neck contracture (BNC) is a bothersome complication following endoscopic treatment for benign prostatic hyperplasia (BPH). The objective of our study was to give a more realistic insight into contemporary endoscopic BNC treatment and to evaluate and identify risk factors associated with inferior outcome. MATERIAL AND METHODS: We identified patients who underwent transurethral treatment for BNC secondary to previous endoscopic therapy for BPH between March 2009 and October 2016. Patients with vesico-urethral anastomotic stenosis after radical prostatectomy were excluded. Digital charts were reviewed for re-admissions and re-visits at our institutions and patients were contacted personally for follow-up. Our non-validated questionnaire assessed previous urologic therapies (including radiotherapy, endoscopic, and open surgery), time to eventual further therapy in case of BNC recurrence, and the modality of recurrence management. RESULTS: Of 60 patients, 49 (82%) and 11 (18%) underwent transurethral bladder neck resection and incision, respectively. Initial BPH therapy was transurethral resection of the prostate (TURP) in 54 (90%) and holmium laser enucleation of the prostate (HoLEP) in six (10%) patients. Median time from prior therapy was 8.5 (IQR 5.3-14) months and differed significantly in those with (6.5 months; IQR 4-10) and those without BNC recurrence (10 months; IQR 6-20; p = 0.046). Thirty-three patients (55%) underwent initial endoscopic treatment, and 27 (45%) repeated endoscopic treatment for BNC. In initially-treated patients, time since BPH surgery differed significantly between those with a recurrence (median 7.5 months; IQR 6-9) compared to those treated successfully (median 12 months; IQR 9-25; p = 0.01). In patients with repeated treatment, median time from prior BNC therapy did not differ between those with (4.5 months; IQR 2-12) and those without a recurrence (6 months; IQR 6-10; p = 0.6). Overall, BNC treatment was successful in 32 patients (53%). The observed success rate of BNC treatment was significantly higher after HoLEP compared to TURP (100% vs. 48%; p = 0.026). Type of BNC treatment, number of BNC treatment, and age at surgery did not influence the outcome. CONCLUSIONS: A longer time interval between previous BPH therapy and subsequent BNC incidence seems to favorably affect treatment success of endoscopic BNC treatment, and transurethral resection and incision appear equally effective. Granted the relatively small sample size, BNC treatment success seems to be higher after HoLEP compared to TURP, which warrants validation in larger cohorts.

Perioperative and Pathological Outcome of Nerve-Sparing Radical Cystectomy With Ileal Neobladder.

Purpose: So far, it has not been described whether the perioperative course and the pathologic outcome of patients who undergo radical cystectomy (RC) with orthotopic bladder substitution differs if nerve sparing (NS) is performed or not. Material and Methods: In all, there were 472 patients who underwent RC between 2012 and 2019 at our department. We performed a retrospective analysis of 116 patients who underwent RC with ileal neobladder. We analyzed perioperative complications according to the Clavien-Dindo classification system, as well as the pathological outcome. Results: Of 116 patients, 68 (58.6%) underwent RC, and 48 (41.4%) underwent NS RC. Clavien-Dindo complications ≥3b occurred in 15 (12.9%) of all patients. Only infectious complications differed among the groups [NS RC: 25 patients (52.1%) vs. RC: 20 patients (29.4%); p = 0.02]. There was no significant difference concerning tumor stage. Concomitant Cis was present in 24 patients (35.3%) of the RC group and in 27 patients (56.3%) of the NS RC group (p = 0.036). Nodal status and positive surgical margin status of the bladder tumor did not differ among the groups. In all, 42 of all male patients (45.7%) had an incidental prostatic carcinoma. Positive surgical margins concerning the prostate carcinoma occurred in six patients, with all cases in the RC group (p = 0.029). Conclusions: Our data suggest that performing NS during RC in carefully selected patients is a safe procedure and does not impair perioperative outcome. Pathological outcome of NS RC is comparable as well.

Novel Biocompatible Adhesive to Remove Stone Dust: Usability Trial in a Kidney Model.

Introduction and Objective: "Clinically insignificant residual fragments" are an independent predictive factor for recurrence of nephrolithiasis. To improve the stone-free rates (SFR), we tested the viability of a novel bioadhesive system for intrarenal embedding and retrieval of residual fragments <1 mm in a kidney model. Materials and Methods: All procedures were performed in a standardized setting, including a kidney model (Kidney module right, Samed GmbH, Dresden) in a plastic basin filled with water. We used a Viper URF flexible ureterorenoscope (fURS) (6.6/8F, Richard Wolf, Knittlingen). A mean amount of 138 mg (standard deviation [SD] ±32.2 mg) of sand grains (range, 0.2-0.8 mm) was inserted in renal calices of the kidney model. We assessed the extraction efficacy of fURS using the bioadhesive system. In total, eight different surgeons performed each one trial, respectively. The endoscopic and macroscopic SFR, the level of the surgeons' experience, and the overall time of stone retrieval were evaluated. Additionally, a survey of the participants was conducted, to assess the contentment with this novel system. Results: The extraction of the sand grains was only possible using the bioadhesive system, otherwise they were too small sized to grab with a retrieval basket. The total SFR was 84% (SD ±11.7%). The operation time (p = 0.052) and the percentage of extracted sand grains (p = 0.194) were not significantly different between experienced and less experienced surgeons. All participants stated that it was a promising technique, which they could imagine using on a daily basis. Conclusions: The bioadhesive system improves the SFR with fragments from 0.2 to 0.8 mm (0% vs 84%). Also, the performance of this operation is not dependent on the surgeon's experience level. This method might improve the SFR in difficult anatomic conditions, that is, lower calices or anomalous kidneys.

Continence and Complication Rates of Artificial Urinary Sphincter Devices (AMS 800) for Parkinson and Stroke Patients with Incontinence after Prostate Surgery: Retrospective Analysis of a Prospective Database.

OBJECTIVES: The artificial urinary sphincter (AUS) is the gold standard treatment for severe stress urinary incontinence (SUI). According to the literature, patients suffering from Parkinson's disease (PD) or stroke (ST) show adverse continence outcomes after prostate surgery and, therefore, constitute a challenging cohort for continence surgery. However, little is known with respect to the results of AUS surgery in these patients. A retrospective analysis of our institutional, prospectively maintained AUS database aims to address this aspect with a focus on surgical and functional outcomes. METHODS AND PATIENTS: All data of patients with an AUS implantation were prospectively collected in our database since 2009. The AUS was implanted according to a standardized protocol and activated at 6 weeks postoperatively at our institution. Further follow-up (FU) consisted of pad-test, uroflowmetry, residual urine, and radiography as well as a standardized questionnaire including the Incontinence Quality of Life questionnaire (I-Quol) and International Consultation on Incontinence questionnaire (ICIQ-SF) and is scheduled at 6 and 24 months and every 2 years thereafter. Patients received a preoperative urodynamic evaluation (UD). Patients with normal voiding and storage function were considered for AUS implantation. All patients performed a preoperative test for manual dexterity. Patients with a history of ST or PD were grouped and compared to nonneurological patients. Primary/secondary endpoints of the study were complications/continence. RESULTS: 234 patients were available for analysis. The median FU was 24 months (interquartile range 7-36). Twenty-four patients (10%) had a neurological history (PD and ST). Neurological patients showed significantly worse outcomes regarding continence (objective/subjective/social continence; p = 0.04/p = 0.02/p = 0.1). Significant differences concerning explantation rates were not observed (p = 1). Kaplan-Meier analysis showed no significant difference regarding explantation-free survival (log-rank p = 0.53). CONCLUSION: AUS implantation shows significantly worse continence rates for neurological patients, despite the fact that all patients showed normal UD results and sufficient manual dexterity. Although neurological patients showed worse outcomes for continence, AUS implantation seems to be a safe and viable treatment for patients with a history of neurological disease.

Contemporary Management of Vesico-Urethral Anastomotic Stenosis After Radical Prostatectomy.

Vesico-urethral anastomotic stenosis is a well-known sequela after radical prostatectomy for prostate cancer and has significant impact on quality of life. This review aims to summarize contemporary therapeutical approaches and to give an overview of the available evidence regarding endoscopic interventions and open reconstruction. Initial treatment may include dilation, incision or transurethral resection. In treatment-refractory stenoses, open reconstruction via an abdominal (retropubic), transperineal or combined abdominoperineal approach is a viable option with high success rates. All of the open surgical procedures are generally accompanied by a high risk of developing de novo incontinence and patients may need further interventions. In such cases, subsequent artificial urinary sphincter implantation is the most common treatment option with the best available evidence.

Buccal mucosal graft urethroplasty for radiation-induced urethral strictures: an evaluation using the extended Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM).

OBJECTIVES: To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. PATIENTS AND METHODS: Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan-Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). RESULTS: Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65-74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28-68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. CONCLUSION: The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.
