RESUMO

BACKGROUND: The oncological impact of perioperative blood transfusions (PBTs) of patients undergoing radical cystectomy (RC) because of bladder cancer (BCa) has been a controversial topic discussed in recent years. The main cause for the contradictory findings of existing studies might be the missing consideration of the storage time of red blood cell units (BUs), donor age, and gender matching. STUDY DESIGN AND METHODS: We retrospectively analyzed BCa patients who underwent RC in our department between 2004 and 2021. We excluded patients receiving BUs before RC, >10 BUs, or RC in a palliative setting. We assessed the effect of blood donor characteristics and storage time on overall survival (OS) and cancer-specific survival (CSS) through univariate and multivariable Cox regression analysis. We also performed a propensity score matching with patients who received BUs and patients who did not on a 1:1 ratio. RESULTS: We screened 1692 patients and included 676 patients for the propensity score matching. In the multivariable analysis, PBT was independently associated with worse OS and CSS (p < .001). Postoperative transfusions were associated with better OS (p = .004) and CSS (p = .008) compared to intraoperative or mixed transfusions. However, there was no influence of blood donor age, storage time, or gender matching on prognosis. DISCUSSION: In our study of BCa patients undergoing RC, we demonstrate that PBT, especially if administered intraoperatively, is an independent risk factor for a worse prognosis. However, storage time, donor age, or gender matching did not negatively affect oncological outcomes. Therefore, the specific selection of blood products does not promise any benefits.

RESUMO

BACKGROUND: Suspicion of testicular torsion represents a urological emergency, necessitating immediate surgery. Comprehensive data on the current trends and perioperative outcomes regarding surgical exploration are sparse. Therefore, we utilized nationwide data on the prevalence and results of this surgery, aiming to provide evidence on this matter. METHODS: We assessed the GeRmAn Nationwide inpatient Data (GRAND) from 2005 to 2021, provided by the Research Data Center of the Federal Bureau of Statistics. We performed multiple regression analyses to evaluate the perioperative outcomes (length of hospital stay, transfusion, and surgical wound infection) after surgical exploration due to suspected testicular torsion based on both the outcome of surgery (orchiectomy, detorsion with preservation of the testicle, and no testicular torsion) and on the department of operation (urological versus non-urological). RESULTS: A total of 81,899 males underwent surgical exploration due to suspected testicular torsion in Germany from 2005 to 2021. Of them, 11,725 (14%) underwent orchiectomy, 30,765 (38%) detorsion with preservation of the testicle and subsequent orchidopexy, and 39,409 (48%) presented no testicular torsion. Orchiectomy was significantly associated with longer length of hospital stay (day difference of 1.4 days, 95%CI: 1.3-1.4, p < 0.001), higher odds of transfusion (1.8, 95% CI: 1.2-2.6, p = 0.002) and surgical wound infections (1.8, 95%CI: 1.4-2.3, p < 0.001) compared to no testicular torsion. The proportion of patients undergoing orchiectomy was significantly lower in urological departments (14%) versus non-urological departments (16%) and the proportion of patients undergoing preservation of testicle after detorsion was significantly higher in urological departments (38%) versus non-urological departments (37%), p < 0.001. Patients undergoing treatment in a urological department were discharged earlier and presented lower odds of transfusion and surgical wound infection (p < 0.001) compared to patients undergoing treatment in a non-urological department. CONCLUSIONS: Nearly half of patients who underwent surgery for suspected testicular torsion did not have intraoperatively the condition confirmed. Patients treated in urological departments had significantly better perioperative outcomes compared to those treated in non-urological departments. Therefore, we advise to refer patients to urological treatment as early as possible.

RESUMO

OBJECTIVES: To determine a data-based optimal annual radical cystectomy (RC) hospital volume threshold and evaluate its clinical significance regarding perioperative mortality, complications, length of hospital stay, and hospital revenues. MATERIAL AND METHODS: We used the German Nationwide inpatient Data, provided by the Research Data Center of the Federal Bureau of Statistics (2005-2020). 95,841 patients undergoing RC were included. Based on ROC analyses, the optimal RC threshold to reduce mortality, ileus, sepsis, transfusion, hospital stay, and costs is 54, 50, 44, 44, 71 and 76 cases/year, respectively. Therefore, we defined an optimal annual hospital threshold of 50 RCs/year, and we also used the threshold of 20 RCs/year proposed by the EAU guidelines to perform multiple patient-level analyses. RESULTS: 28,291 (29.5%) patients were operated in low- (< 20 RC/year), 49,616 (51.8%) in intermediate- (20-49 RC/year), and 17,934 (18.7%) in high-volume (≥ 50 RC/year) centers. After adjusting for major risk factors, high-volume centers were associated with lower inpatient mortality (OR 0.72, 95% CI 0.64-0.8, p < 0.001), shorter length of hospital stay (2.7 days, 95% CI 2.4-2.9, p < 0.001) and lower costs (457 Euros, 95% CI 207-707, p < 0.001) compared to low-volume centers. Patients operated in low-volume centers developed more perioperative complications such as transfusion, sepsis, and ileus. CONCLUSIONS: Centralization of RC not only improves inpatient morbidity and mortality but also reduces hospital stay and costs. We propose a threshold of 50 RCs/year for optimal outcomes.

RESUMO

INTRODUCTION: Radical cystectomy (RC) is the gold standard for muscle-invasive bladder cancer. Nevertheless, RC is associated with substantial perioperative morbidity and mortality. We aimed to evaluate the role of important perioperative risk factors in predicting long-term survival after RC. METHODS: An analysis of the prospective cohort of patients undergoing open RC from 2004 to 2023 at our center was performed. Patients who died within one month after RC were excluded from the study. A univariate and multivariable Cox regression analysis was performed to assess the role of sex, age, urinary diversion, preoperative values of creatinine and hemoglobin, first-day postoperative values of CRP, leucocytes, and thrombocytes, perioperative Clavien-Dindo complications, perioperative chemotherapy, admission to the intensive or intermediate care unit, as well as type of histology, pathologic T-stage, positive lymph nodes, and positive surgical margins on predicting the long-term overall survival after RC. For all analyses hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) were estimated. RESULTS: A total of 1,750 patients with a median age of 70 years (IQR: 62-76) were included. Of them, 1,069 (61%) received ileal conduit and 650 (37%) neobladder. Overall, 1,016 (58%) perioperative complications occurred. At a median follow-up of 31 months (IQR: 12-71), 884 (51%) deaths were recorded. In the multivariable Cox regression analysis, increasing age (HR: 1.03, 95%CI: 1.02-1.04, p < 0.001), higher preoperative creatinine values (HR: 1.27, 95%CI: 1.12-1.44, p < 0.001), lower preoperative hemoglobin values (HR: 0.93, 95%CI: 0.89-0.97, p = 0.002), higher postoperative thrombocyte values (HR: 1.01, 95%CI: 1.01-1.02, p = 0.02), Clavien-Dindo 1-2 complications (HR: 1.26, 95%CI: 1.03-1.53, p = 0.02), Clavien-Dindo 3-4 complications (HR: 1.55, 95%CI: 1.22-1.96, p < 0.001), locally advanced bladder cancer (HR: 1.29, 95%CI: 1.06-1.55, p = 0.009), positive lymph nodes (HR: 1.74, 95%CI: 1.45-2.11, p < 0.001), and positive surgical margins (HR: 1.61, 95%CI: 1.29-2.01, p < 0.001) negatively affected long-term survival. CONCLUSION: Beside increased age and worse oncological status, impaired renal function, lower preoperative hemoglobin values, higher postoperative thrombocyte values, and perioperative complications are independent risk factors for mortality in the long term in patients undergoing open RC.

RESUMO

INTRODUCTION: Transurethral resection of the bladder (TUR-BT) is the standard initial treatment and diagnosis of bladder cancer (BC). Of note, upstaging into muscle-invasive disease (MIBC) during re-resection occurs in a significant proportion of patients. This study aimed to define risk factors at initial TUR-BT for upstaging. METHODS: TUR-BT between 2009 and 2021 were retrospectively screened (n = 3,237). We included patients with visible tumors that received their primary and re-TUR-BT at our institution. Upstaging was defined as pathological tumor stage progression into MIBC at re-TUR-BT. Clinicopathological variables were analyzed for the impact on upstaging. RESULTS: Two hundred and sixty-six patients/532 TUR-BTs were included in the final analysis. Upstaging occurred in 7.9% (21/266) patients. Patients with upstaging presented with stroma-invasive and papillary non-muscle-invasive BC at primary resection in 85.7% (18/21) and 14.3% (3/21), respectively. Detrusor muscle at primary TUR-BT was significantly less present in patients with upstaging (4.1 vs. 95.9%; p < 0.001). After multivariate analysis, solid tumor configuration (HR: 4.17; 95% CI: 1.23-14.15; p = 0.022) and missing detrusor muscle at initial TUR-BT (HR: 3.58; 95% CI: 1.05-12.24; p = 0.043) were significant risk factors for upstaging into MIBC. CONCLUSIONS: The current study defined two major risk factors for upstaging: missing detrusor muscle and solid tumor configuration. We propose that a second resection should be performed earlier if these risk factors apply.

RESUMO

INTRODUCTION: Studies assessing the impact of preoperative and first-day postoperative values of leukocytes, thrombocytes, and platelet/leukocyte ratio (PLR) after radical cystectomy (RC) are sparse. We aimed to assess the impact of these factors on long-term survival after RC. METHODS: An analysis of patients undergoing open RC from 2004 to 2023 at our center was performed. Leukocytosis was defined as ≥8,000 leukocytes/µL and thrombocytosis as ≥400,000 thrombocytes/µL. Similarly, the cutoff for PLR was set at 28. A multivariable Cox regression analysis was performed to assess the role of leukocytosis, thrombocytosis, and PLR on long-term survival after RC. For all analyses, hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) were estimated. RESULTS: A total of 1,817 patients with a median age of 70 years (interquartile range [IQR]: 62-77) were included. Overall, 804 (44%), 175 (10%), and 1,296 (71%) patients presented with leukocytosis, thrombocytosis, and PLR ≥28 preoperatively. Accordingly, 1,414 (78%), 37 (2%), and 249 (14%) patients presented with leukocytosis, thrombocytosis, and PLR ≥28 on the first day after RC. At a median follow-up of 26 months (IQR: 8-68) after RC, 896 (49%) patients died. In the multivariate Cox regression analysis after adjusting for major perioperative risk factors, only preoperative leukocytosis (HR: 1.3, 95% CI: 1.1-1.6, p = 0.01), as well as both preoperative and first-day thrombocytosis (HR: 2.1, 95% CI: 1.5-2.9, and HR: 2.8, 95% CI: 1.6-5.1, p < 0.001, accordingly) were associated with worse overall survival. CONCLUSION: PLR should not be used as a prognostic marker for survival after RC. On the contrary, preoperative leukocytosis, as well as preoperative and first-day thrombocytosis should raise awareness among clinicians performing RC since they were independently associated with worse survival after RC.

RESUMO

OBJECTIVES: To explore whether Christmas might be a risk factor for penile fractures due to the Christmas spirit related to the intimacy and euphoria of these holly jolly days. PATIENTS AND METHODS: We evaluated the incidence of penile fractures during Christmas and New Year's Eve through the GeRmAn Nationwide inpatient Data (GRAND) from the Research Data Center of the Federal Bureau of Statistics (Wiesbaden, Germany). Furthermore, we assessed the impact of COVID-19 on penile fractures and their seasonality. RESULTS: A total of 3,421 patients with a median, interquartile range (IQR) age of 42 (32-51) years had a penile fracture requiring a hospital stay from 2005 to 2021. In all, 40 (1.2%) penile fractures occurred in 51 days of Christmas (from 24/12 to 26/12 in each year). The daily incidence of penile fractures during Christmas was 0.78 with an incidence rate ratio (IRR) of 1.43 (95% confidence interval [CI] 1.05-1.95, P = 0.02). If every day was like Christmas, 43% more penile fractures would have occurred in Germany from 2005 on. Interestingly, only 28 (0.82%) penile fractures occurred during the New Year's Eve period (31/12 to 02/01 from 2005 to 2021). This resulted in an IRR of 0.98 (95% CI 0.69-1.5, P = 0.98) in the New Year's Eve period. Most patients with penile fractures were admitted to hospital at the weekend (n = 1,322; IRR 1.58, 95% CI 1.48-1.69; P < 0.001). Summer was also associated with more penile fractures (n = 929; IRR 1.11, 95% CI 1.03-1.19; P = 0.008). Both the COVID-19 pandemic (n = 385; IRR 1.06, 95% CI 0.95-1.18, P = 0.29) and its lockdown period (n = 93; IRR 1, 95% CI 0.82-1.23; P = 0.96) did not affect the incidence of penile fractures. CONCLUSION: The incidence of penile fractures displays a seasonality. Last Christmas penile fractures occurred more often. This year to save us from tears, we will NOT do something special (the new Christmas hit of the year).

RESUMO

OBJECTIVE: To assess the added value of concurrent systematic randomised ultrasonography-guided biopsy (SBx) to multiparametric magnetic resonance imaging (mpMRI)-targeted biopsy and the additional rate of overdiagnosis of clinically insignificant prostate cancer (ciPCa) by SBx in a large contemporary, real-world cohort. PATIENTS AND METHODS: A total of 1552 patients with positive mpMRI and consecutive mpMRI-targeted biopsy and SBx were enrolled. Added value and the rate of overdiagnosis by SBx was evaluated. PRIMARY OUTCOME: added value of SBx, defined as detection rate of clinically significant PCa (csPCa; International Society of Urological Pathology [ISUP] Grade ≥2) by SBx, while mpMRI-targeted biopsy was negative or showed ciPCa (ISUP Grade 1). SECONDARY OUTCOME: rate of overdiagnosis by SBx, defined as detection of ciPCa in patients with negative mpMRI-targeted biopsy and PSA level of <10 ng/mL. RESULTS: Detection rate of csPCa by mpMRI-targeted biopsy and/or SBx was 753/1552 (49%). Added value of SBx was 145/944 (15%). Rate of overdiagnosis by SBx was 146/656 (22%). Added value of SBx did not change when comparing patients with previous prostate biopsy and biopsy naïve patients. In multivariable analysis, a Prostate Imaging-Reporting and Data System (PI-RADS) 4 index lesion (odds ratio [OR] 3.19, 95% confidence interval [CI] 1.66-6.78; P = 0.001), a PI-RADS 5 index lesion (OR 2.89, 95% CI 1.39-6.46; P = 0.006) and age (OR 1.05, 95% CI 1.03-1.08; P < 0.001) were independently associated with added value of SBx. CONCLUSIONS: In our real-world analysis, we saw a significant impact on added value and added rate of overdiagnosis by SBx. Subgroup analysis showed no significant decrease of added value in any evaluated risk group. Therefore, we do not endorse omitting concurrent SBx to mpMRI-guided biopsy of the prostate.

RESUMO

INTRODUCTION: As a high-quality TUR-BT is important to ensure adequate treatment for bladder cancer patients, the aim of the current study is to investigate the impact of patient-related, surgical and tumor-specific parameters on detrusor muscle (DM) absence (primary objective) and to assess the impact of DM on the prognosis after a TUR-BT (secondary objective). PATIENTS AND METHODS: Transurethral resection of bladder tumors (TUR-BTs) between 2009 and 2021 were retrospectively screened (n = 3237). We included 2058 cases (1472 patients) for the primary and 472 patients for secondary objective. Clinicopathological variables including tumor size, localization, multifocality, configuration, operation time and skill-level of the urologist were assessed. We analyzed predictors for missing DM and prognostic factors for recurrence-free survival (RFS) for the complete cohort and subgroups. RESULTS: DM was present in 67.6% (n = 1371/2058). Surgery duration (continuous, minutes) was an independent predictor for absence of DM in the complete cohort (OR:0.98, r:0.012, 95%CI:0.98-0.99, p = 0.001). Other significant risk factors for missing DM were papillary tumors (OR:1.99, r:0.251, 95%CI:1.22-3.27, p = 0.006) in the complete cohort and bladder-roof and posterior-bladder-wall localization for re-resections. Absence of DM in high-grade BC correlated with reduced RFS (HR:1.96, 95%CI:1.0-3.79, p = 0.045). CONCLUSION: Sufficient time for a TUR-BT is mandatory to assure DM in the TUR-BT specimen. Also, cases with more difficult locations of bladder tumors should be performed with utmost surgical diligence and endourological training should incorporate how to perform such operations. Of note, DM correlates with improved oncological prognosis in high-grade BC.

RESUMO

INTRODUCTION: This study aimed to evaluate the impact of chronological and biological age on perioperative complications and survival after radical nephroureterectomy (RNU). Elderly patients with upper-tract urothelial carcinoma might be overtreated by RNU. METHODS: We retrospectively analyzed patients undergoing RNU. To evaluate the perioperative risk, patients were divided into four groups (<75; 75-79; 80-84; ≥85 years). The endpoints are perioperative complications and survival (overall survival [OS]). We calculated a risk score including chronological and biological age (Eastern cooperative oncology group performance status). Statistical analysis was performed by Kruskal-Wallis, Mann-Whitney U, χ2, log-rank, and Breslow tests. RESULTS: 194 patients were included in the study. Median follow-up was 25.5 months. Elderly cohorts ≥2 presented a higher number of days in intensive care unit following RNU (p < 0.001). Complication rates increased from cohort 1-4 with rates of 48.8%; 55.2%; 92.0%; 85.7% (p < 0.001). Median survival was 115, 55, 28, and 20 months for cohorts 1, 2, 3, and 4, respectively. The combined risk score revealed a significant 5-year OS benefit for patients with score 0 (82.3%) compared to score 1 (46.0%) and score 2 (15.0%; p < 0.001). DISCUSSION/CONCLUSION: We evaluated the impact of chronological and biological age on perioperative complications and survival after RNU. A combined risk score of chronological and biological age correlates with survival after RNU.

RESUMO

PURPOSE: To provide first evidence of lymph node (LN) staging using CT scan and its prognostic value in variant histologies of bladder cancer. This knowledge may optimize patient management with variant histologies based on CT morphological findings. METHODS: Preoperative CT scans of patients with variant histologies who underwent RC between 2004 and 2019 were reanalyzed by two independent radiologists in a blinded review process. Specificity, sensitivity, and accuracy for LN staging as well as LN characteristics were evaluated. Correlation with survival was investigated by Kaplan-Meier method, log-rank test and multivariate analysis. RESULTS: 1361 patients with primary tumor of the bladder underwent RC, of which 163 (12%) patients revealed variant histologies. 65 (47.8%) patients have shown an urothelial variant (UV) and 71 (52.2%) a non-urothelial variant (NUV). LN metastases were found in 18 (27.7%) patients with UV and 21 (29.6%) patients with NUV. The accuracy to detect LN metastasis for all variant histologies was 62% with a sensitivity of 46% and a specificity of 70%. Subgroups of UV and NUV revealed an accuracy of 67% and 57%. An increased number of regional LN (HR 2.8; 1.34-6.18) and the loss of fatty hilum (HR 0.36, 0.17-0.76) were prognostic parameters. In multivariate analysis, a fatty hilum (HR 0.313, 0.104-0.945) and the presence of lymph node metastases (HR 2.866, 1.140-7.207) were prognostic. CONCLUSION: This first study on CT morphological behavior of variant histologies revealed an accuracy of UV and NUV comparable to UC with low specificity for all variant histologies. CT scan prior RC should be interpreted in regard to histological subtypes.

RESUMO

OBJECTIVE: To determine the impact of asymptomatic bacteriospermia on semen quality in subfertile men. METHODS: We conducted a retrospective, single-centre cohort study in 1300 subfertile men. In those diagnosed with asymptomatic bacteriospermia we performed univariate and multivariate logistic regression models to evaluate the strain-specific association with semen parameters. RESULTS: Asymptomatic bacteriospermia was diagnosed in 3.2% of patients. The microbiological semen analysis revealed a poly-microbial result in 60%. The most common bacterial species were coagulase-negative Staphylococci species (71.4%), Streptococcus viridans (50.0%) and Enterococcus faecalis (26.2%). Sexually transmitted pathogens were identified in 11.9% of semen samples. The detection of Streptococcus viridians or Haemophilus parainfluenzae correlated with impaired sperm morphology (p < 0.05). The presence of coagulase-negative Staphylococci species or Enterococcus faecalis was associated with pathological low counts of live spermatozoa (p < 0.05). In multivariate analysis only Enterococcus faecalis showed a significant impact on sperm concentration (OR 4.48; 95% CI 1.06-22.10; p = 0.041). CONCLUSIONS: Asymptomatic bacteriospermia has always been a subject of great controversy. There is still an ongoing debate whether to treat or not to treat. Here, we demonstrate that asymptomatic bacteriospermia is clearly associated with impaired semen quality. Our findings speak in favour of strain-specific interactions with semen parameters. Especially Enterococcus faecalis seriously affects sperm concentration.

RESUMO

PURPOSE: To investigate the expression of the receptor protein ACE-2 alongside the urinary tract, urinary shedding and urinary stability of SARS-CoV-2 RNA. METHODS: Immunohistochemical staining was performed on tissue from urological surgery of 10 patients. Further, patients treated for coronavirus disease (COVID-19) at specialized care-units of a university hospital were assessed for detection of SARS-CoV-2 RNA in urinary samples via PCR, disease severity (WHO score), inflammatory response of patients. Finally, the stability of SARS-CoV-2 RNA in urine was analyzed. RESULTS: High ACE-2 expression (3/3) was observed in the tubules of the kidney and prostate glands, moderate expression in urothelial cells of the bladder (0-2/3) and no expression in kidney glomeruli, muscularis of the bladder and stroma of the prostate (0/3). SARS-CoV-2 RNA was detected in 5/199 urine samples from 64 patients. Viral RNA was detected in the first urinary sample of sequential samples. Viral RNA load from other specimen as nasopharyngeal swabs (NPS) or endotracheal aspirates revealed higher levels than from urine. Detection of SARS-CoV-2 RNA in urine was not associated with impaired WHO score (median 5, range 3-8 vs median 4, range 1-8, p = 0.314), peak white blood cell count (median 24.1 × 1000/ml, range 5.19-48.1 versus median 11.9 × 1000/ml, range 2.9-60.3, p = 0.307), peak CRP (median 20.7 mg/dl, 4.2-40.2 versus median 11.9 mg/dl, range 0.1-51.9, p = 0.316) or peak IL-6 levels (median: 1442 ng/ml, range 26.7-3918 versus median 140 ng/ml, range 3.0-11,041, p = 0.099). SARS-CoV-2 RNA was stable under different storage conditions and after freeze-thaw cycles. CONCLUSIONS: SARS-CoV-2 RNA in the urine of COVID-19 patients occurs infrequently. The viral RNA load and dynamics of SARS-CoV-2 RNA shedding suggest no relevant route of transmission through the urinary tract.

RESUMO

INTRODUCTION: Biomarkers are known predictors for survival after radical cystectomy (RC) and can improve patient stratification. Yet, it remains unclear how age influences their prognostic value. The current study aimed to assess the impact of age on standard prognostic biomarkers in different age-groups. MATERIALS AND METHODS: Overall, 1,014 patients undergoing RC for bladder cancer were included. Patients were divided into age-groups (I - <60, II - 60-69, III - 70-79, and IV - ≥80). C-reactive protein (CRP), hemoglobin (Hb), thrombocytes, and leucocytes prior to RC were used as biomarkers. The Kaplan-Meier method and log-rank test were used to compare overall survival (OS) and cancer-specific survival (CSS). For independent predictors of survival, multivariate models were applied. RESULTS: Absolute levels of biomarkers except CRP revealed a significant decrease with increasing age. We found low Hb to be associated with impaired CSS in groups II (2.05 [1.32-3.17]; p = 0.001), III (2.83 [2.01-4.00]; p < 0.001), and IV (1.79 [1.12-2.84]; p = 0.014). Thrombocytes above the cutoff were associated with impaired CSS and OS in groups II, III, and IV for CSS and OS. Leukocytes were associated with impaired CSS and OS in group II (2.11 [1.38-3.23]; p < 0.001 and 1.99 [1.36-2.90]; p < 0.001) and III (1.70 [1.08-2.67]; p = 0.021 and 1.80 [1.25-2.58]; p = 0.002). Elevated CRP was associated with impaired CSS and OS across all groups. CONCLUSION: Biomarkers are predictors for survival after RC. Yet, their impact on survival is less in the oldest patient group. Therefore, careful patient stratification and treatment administration should be considered in elderly patients. Further investigations are needed to fully understand the underlying mechanisms.

RESUMO

PURPOSE: Contrast-enhanced CT scan is the standard staging modality for patients with bladder cancer undergoing radical cystectomy (RC). Involvement of lymph nodes (LN) determines prognosis of patients with bladder cancer. The detection of LN metastasis by CT scan is still insufficient. Therefore, we investigated various CT scan characteristics to predict lymph node ratio (LNR) and its impact on survival. Also, pre-operative CT scan characteristics might hold potential to risk stratify cN+ patients. MATERIALS AND METHODS: We analyzed preoperative CT scans of patients undergoing RC in a tertiary high volume center. Retrospectively, local tumor stage and LN characteristics such as size, morphology (MLN) and number of loco-regional LN (NLN) were investigated and correlation to LNR and survival was analyzed. CT scan characteristics were used to develop a risk stratification using Kaplan-Maier and multivariate analysis. RESULTS: 764 cN0 and 166 cN+ patients with complete follow-up and imaging data were included in the study. Accuracy to detect LN metastasis and locally advanced tumor stage in CT scan was 72% and 62%. LN larger than 15mm in diameter were significantly associated with higher LNR (p=0.002). Increased NLN correlated with decreased CSS and OS (p=0.001: p=0.002). Furthermore, CT scan based scoring system precisely differentiates low-risk and high-risk profiles to predict oncological outcome (p < 0.001). CONCLUSION: In our study, solely LN size >15mm significantly correlated with higher LNR. Identification of increased loco-regional LN was associated with worse survival. For the first time, precise risk stratification based on computed-tomography findings was developed to predict oncological outcome for clinical lymph node-positive patients undergoing RC.

RESUMO

PURPOSE: To investigate differences in standard preoperative inflammatory markers in patients with urothelial carcinoma (UC) and variant histologies undergoing radical cystectomy (RC) and determine its impact on survival. METHODS: Patients undergoing RC at an academic high-volume center were retrospectively analyzed. Preoperatively taken CRP, leukocytes, hemoglobin (Hb), and thrombocytes were analyzed as routine inflammatory biomarkers. Log-rank tests and Kruskal-Wallis analysis were used to calculate for differences in survival and in blood levels of biomarkers. RESULTS: 886 patients with complete follow-up and UC or variant histology underwent RC at our institution between 2004 and 2019. Although variant histology presents with significantly higher t stage than UC, cancer-specific survival (CSS) of UC (1-year-CSS: 93%) is not significantly different to variant histology of UC with squamous differentiation (UCSD, 1-year-CSS: 81%), squamous cell carcinoma (SCC, 1-year-CSS: 82%), and adenocarcinoma (AC, 1-year-CSS: 81%). In UC, alterations in all biomarkers except leukocytes beyond routine cut-off values were associated with poor survival (p < 0.01), whereas Hb beyond cut-off values are associated with poor prognosis in SCC (p < 0.05). CRP levels are significantly elevated in UCSD and SCC at time of surgery compared to UC (p < 0.05). CONCLUSION: Inflammatory biomarkers reveal distinctive patterns across UC and variant histologies of bladder cancer. As inflammation might play an important role in cancer progression, further research is warranted to understand those molecular mechanisms and their potential therapeutic impact in variant histology of bladder cancer.

RESUMO

AIMS: Radical cystectomy and urinary diversion impact various dimensions of patients' health-related-quality-of-life (HRQOL). Yet, less is known about salvage cystectomy as a last-line option for treatment-refractory benign diseases. Therefore, our aim is to provide HRQOL data from a contemporary cohort of open salvage cystectomies for benign conditions. METHODS: Fifty-four consecutive patients were enrolled in one single tertiary referral center. Analysis was limited to patients undergoing urinary diversion via ileal conduit (IC). Complications were assessed via Clavien-Dindo-scale. HRQOL was measured using the validated European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-BLM30 questionnaire. HRQOL QLQ-C30 domains were measured preoperatively and up to 3 years postoperatively. Longitudinal changes were analyzed using Friedman's rank test. Primary endpoint was good general HRQOL based on QLQ-C30 global health status (GHS). Multivariate analysis was performed using logistic regression models with a step-wise backward selection procedure. RESULTS: Longitudinal analysis of HRQOL subdomains revealed significantly improved pain (p = .005) and fatigue (p = .002) scores as well as improved social functioning (p = .038). Furthermore, general HRQOL (GHS scores) improved significantly during the follow-up period (28.0 vs. 50.6 [36 months], p = .045). In multivariate analysis, the indication for salvage cystectomy could not be identified as an independent predictor for good general HRQOL. We observed a total number of 10 (41.7%) high-grade (Clavien ≥III) 90 day-complications. Limitations include limited follow-up rates at respective time-points. CONCLUSION: Salvage cystectomy and IC can be safely performed as a last-line treatment for benign conditions and increases general HRQOL in the long-term follow-up. Thus, it can play a role in a holistic approach for a challenging clinical setting.

RESUMO

BACKGROUND: This study investigates the effect of classical music, music of patients' own choice, or no music on pain reduction during elective cystoscopy. OBJECTIVES: The aim of the study was to describe the effect of listening to classical music, music of patients' own choice, or no music on patient's pain and satisfaction rates when carrying out an elective cystoscopy and the effect on the assessment capability of the performing urologist. DESIGN, SETTING, AND PARTICIPANTS: This randomized trial included 127 patients undergoing elective cystoscopy at the Urological Department of the University Clinic of Munich between June 2019 and March 2020. Outcome Measurements and Statistical Analysis: Patients were assigned randomly to 3 groups: group I: listening to standardized classical music (n = 35), group II: listening to music according to the patients' choice (n = 34), and control group III: no music (n = 44). Prior to cystoscopy, anxiety levels were assessed by the Beck Anxiety Inventory (BAI). The Visual Analog Scale (VAS, range 1-100) was used for a self-assessment of pain, discomfort, and satisfaction. Statistical analysis was done with Spearman's rank correlation and t-tests. RESULTS AND LIMITATIONS: The median age was 63 (range 27-91) years. The duration of cystoscopy was 5.7 (1-30) min. Patients had undergone a median of 2.3 cystoscopies in the past. Between giving informed consent and cystoscopy, patients had to wait for a median of 64 (0-260) min. The median VAS pain score was significantly lower in group I at 1.7 and group II at 2.3 versus 5.2 in the control group III (p < 0.001). The control group III had significantly worse pain and patient satisfaction rates compared with groups I and II. Group I had a significant lower VAS pain score than groups II and III (p < 0.001). Classical music also increased the assessment capability of the preforming urologist. CONCLUSIONS: Listening to music during elective cystoscopy significantly reduces pain and distress and leads to higher patient and surgeon satisfaction. We recommend listening to classical music or music chosen by the patients during outpatient flexible/rigid cystoscopy in daily clinical routine. Patient Summary: In this study, we found that patients who listened to classical music or music of their own choice while undergoing a cystoscopy showed significant reduction of pain and distress.

RESUMO

PURPOSE: With a median age at diagnosis of 73 years, bladder cancer has the highest median age of all cancers. Age alone seems to be an independent risk factor for developing the disease with peak age advancing into the range of 85 years. As demographic changes will lead to an ever more aging population in western countries, incidence of advanced age malignancies will rise. We, therefore, analyzed a contemporary radical cystectomy (RC) series at a single high-volume center on patients undergoing RC for urothelial carcinoma of the bladder (UCB). We aim to evaluate the feasibility of RC in the oldest-old patient cohort by assessing perioperative complications and long-term outcome. MATERIALS AND METHODS: We retrospectively analyzed data of 1,278 consecutive patients who underwent RC for UCB at our tertiary referral center between 2004 and 2019. A total of 408 patients were aged 75-97 years at the time of RC and were further divided into 2 groups: 75-84 years of age (group 1) and ≥85 years of age (group 2). Median follow-up was 23 months. Outcome was analyzed using the χ2 test, Mann-Whitney U test, Kaplan-Meier method, and log-rank test. RESULTS: Perioperative Clavien-Dindo grade ≥III complications were seen in 25.1% (92/366) of group 1 patients and 35.7% (15/42) of group 2 patients (p = 0.073). Thirty- and 90-day mortality was 3.3 and 8.7% in group 1 and 4.8 and 14.3% in group 2 (p = 0.617 and p = 0.242, respectively). Three-year overall survival was 54.6% in group 1 and 31.3% in group 2 (p = 0.03). Three-year cancer-specific survival was 64.8% in group 1 and 38.8% in group 2 (p = 0.037). Recurrence-free survival was 105 months in group 1 and 12 months in group 2 (p = 0.039). CONCLUSION: In light of increasing life expectancy in western nations, we sought to evaluate the impact of age in a large series of elderly patients undergoing RC for UCB. We found that RC offers acceptable perioperative complication rates in the oldest-old patient cohort (≥85 years). Therefore, RC for UCB can be offered as a viable treatment option even in the oldest patients.

RESUMO

Background: Radical cystectomy (RC) with the formation of an ileal orthotopic neobladder (ONB) may adversely affect long-term health-related quality of life (HRQOL). An advanced age at the time of ONB construction could further exacerbate the decline in HRQOL. This study aims to establish an evidence-based age threshold at the time of RC with ONB, beyond which a significant deterioration in HRQOL is observed. Methods: We retrospectively analyzed all bladder cancer patients in our department between 2013 and 2022 that fulfilled the EORTC-QLQ-C30 questionnaire preoperatively, as well as at 3 and 12 months after RC with ONB. Patients receiving neoadjuvant or adjuvant chemotherapy or benign/palliative RC were excluded. Results: Overall, 120 patients (81% males) with a mean age of 66 ± 9.6 years underwent RC with ONB and fulfilled the selection criteria. The Global Health Status (GHS) of the EORTC-QLQ-C30 was 64 ± 23 preoperatively, was 64 ± 20 three months postoperatively, and was 68 ± 23 twelve months postoperatively. Overall, 80 (67%) patients presented an increase in GHS at twelve months compared to their preoperative values. The perioperative complications did not differ between patients with decreased and increased GHS. Patients with increased GHS had values of 58 ± 24 preoperatively, 67 ± 19 at 3 months, and 77 ± 16 at 12 months. Patients with decreased GHS had values of 76 ± 16 preoperatively, 57 ± 21 at 3 months, and 50 ± 25 at 12 months. Using ROC analyses with Youden's index, we defined a threshold of 70 years, after which RC with ONB may lead to worse GHS twelve months postoperatively. Worse continence outcomes were the only perioperative and long-term parameters that predicted worse HRQOL in elderly patients. Conclusions: Based on HRQOL, we suggest that RC with an ileal conduit as a urinary diversion should be recommended in patients older than 70 years.
