Trends and outcomes of hospitalized patients with priapism in Germany: results from the GRAND study.

We aimed to provide evidence on the trends and in-hospital outcomes of patients with low- and high-flow priapism through the largest study in the field. We used the GeRmAn Nationwide inpatient Data (GRAND), provided by the Research Data Center of the Federal Bureau of Statistics (2008-2021), and performed multiple patient-level analyses. We included 6,588 men with low-flow and 729 with high-flow priapism. Among patients with low-flow priapism, 156 (2.4%) suffered from sickle cell disease, and 1,477 (22.4%) patients required shunt surgery. Of them, only 37 (2.5%) received a concomitant penile prosthesis implantation (30 inflatable and 7 semi-rigid prosthesis). In Germany, the total number of patients with low-flow priapism requiring hospital stay has steadily increased, while the number of patients with high-flow priapism requiring hospital stay has decreased in the last years. Among patients with high-flow priapism, 136 (18.7%) required selective artery embolization. In men with low-flow priapism, sickle cell disease was associated with high rates of exchange transfusion (OR: 21, 95% CI: 14-31, p < 0.001). The length of hospital stay (p = 0.06) and the intensive care unit admissions (p = 0.9) did not differ between patients with low-flow priapism due to sickle cell disease versus other causes of low-flow priapism. Accordingly, in men with high-flow priapism, embolization was not associated with worse outcomes in terms of length of hospital stay (p > 0.9), transfusion (p = 0.8), and intensive care unit admission (p = 0.5). Low-flow priapism is an absolute emergency that requires shunt surgery in more than one-fifth of all patients requiring hospital stay. On the contrary, high-flow priapism is still managed, in most cases, conservatively.

mpMRI-targeted biopsy of the prostate in men ≥ 75 years. 7-year report from a high-volume referral center.

OBJECTIVE: Multiparametric magnetic resonance imaging (mpMRI) -Ultrasound- fusion guided biopsy of the prostate (FBx) is the new gold standard for the detection of prostate cancer. Hallmark studies showing superior detection rates of FBx over randomized biopsies routinely excluded patients≥75 years and information on outcome of FBx on this patient cohort is sparse. As a large referral center, we have performed FBx on a substantial number of patients this age. By evaluating outcome of FBx of patients over the age of 75 years we wanted to close the gap of knowledge on this patient cohort. MATERIALS AND METHODS: Between 2015 -2022, 1577 patients underwent FBx at our department and were considered for analysis. Clinical and histopathological parameters were recorded. Clinical data comprised age at FBx, serum level of Prostate-specific antigen (PSA), prostate volume, PSA-density, history of previous biopsies of the prostate, result of the digital rectal examination (DRE) and assessment of the indexlesion of mpMRI according to the Prostate Imaging and Reporting Data System (PI-RADS). Univariate analysis and multivariable logistic regression was used to identify age barrier of 75 years as a potential risk factor of detection of clinically significant prostate cancer by FBx. RESULTS: 379/1577 patients (24%) were≥75 years and 1198/1577 (76%) patients were < 75 years, respectively. Preoperative PSA was significantly higher in patients≥75 years compared to patients < 75 years (9.54 vs. 7.8, p < 0.001). Patients≥75 years presented significantly more often with mpMRI target lesions classified as PI-RADS 5 compared to patients < 75 years (45% vs. 29%, p < 0.001). Detection rate of clinically significant prostate cancer was significantly higher in patients≥75 years compared to patients < 75 years (63% vs. 43%, p < 0.001). Aggressive prostate cancer grade ISUP 5 was significantly more often detected in patients≥75 years compared to patients < 75 years (13% vs. 8%, p = 0.03). On multivariable logistic regression model adjusted for PSA and PI-RADS score, age barrier of 75 years was identified as a significant risk factor for the detection of clinically significant prostate cancer by FBx (OR: 1.77, 95% CI: 1.36 -2.31, p < 0.001). CONCLUSION: After evaluation of a large patient cohort, we show that age≥75 years represents a significant risk factor for the detection of clinically significant prostate cancer. Further studies on mid- and long term outcome are necessary to draw conclusions for clinical decision making in this patient cohort.

Reliability and practicability of PSMA-RADS 1.0 for structured reporting of PSMA-PET/CT scans in prostate cancer patients.

OBJECTIVES: As structured reporting is increasingly used in the evaluation of prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) for prostate cancer, there is a need to assess the reliability of these frameworks. This study aimed to evaluate the intra- and interreader agreement among readers with varying levels of experience using PSMA-RADS 1.0 for interpreting PSMA-PET/CT scans, even when blinded to clinical data, and therefore to determine the feasibility of implementing this reporting system in clinical practice. METHODS: PSMA-PET/CT scans of 103 patients were independently evaluated by 4 readers with different levels of experience according to the reporting and data system (RADS) for PSMA-PET/CT imaging PSMA-RADS 1.0 at 2 time points within 6 weeks. For each scan, a maximum of five target lesions were freely chosen and stratified according to PSMA-RADS 1.0. Overall scan score and compartment-based scores were assessed. Intra- and interreader agreement was determined using the intraclass correlation coefficient (ICC). RESULTS: PSMA-RADS 1.0 demonstrated excellent interreader agreement for both overall scan scores (ICC ≥ 0.91) and compartment-based scores (ICC ≥ 0.93) across all four readers. The framework showed excellent intrareader agreement for overall scan scores (ICC ≥ 0.86) and compartment-based scores (ICC ≥ 0.95), even among readers with varying levels of experience. CONCLUSIONS: PSMA-RADS 1.0 is a reliable method for assessing PSMA-PET/CT with strong consistency and agreement among readers. It shows great potential for establishing a standard approach to diagnosing and planning treatment for prostate cancer patients, and can be used confidently even by readers with less experience. CLINICAL RELEVANCE STATEMENT: This study underlines that PSMA-RADS 1.0 is a valuable and highly reliable scoring system for PSMA-PET/CT scans of prostate cancer patients and can be used confidently by radiologists with different levels of experience in routine clinical practice. KEY POINTS: PSMA-RADS version 1.0 is a scoring system for PSMA-PET/CT scans. Its reproducibility needs to be analyzed in order to make it applicable to clinical practice. Excellent interreader and intrareader agreement for overall scan scores and compartment-based scores using PSMA-RADS 1.0 were seen in readers with varying levels of experience. PSMA-RADS 1.0 is a reliable tool for accurately diagnosing and planning treatment for prostate cancer patients, and can be used confidently in clinical routine.

Added value of randomised biopsy to multiparametric magnetic resonance imaging-targeted biopsy of the prostate in a contemporary cohort.

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.

Perioperative outcomes of penile prosthesis implantation in Germany: results from the GRAND study.

We aimed to assess the recommended annual hospital volume for inflatable penile prosthesis implantation (PPI) and to provide evidence on perioperative outcomes of semi-rigid and inflatable PPI in Germany. We used the GeRmAn Nationwide inpatient Data (GRAND) from 2005 to 2021 and report the largest study to date with 7,222 patients. 6,818 (94.4%) patients underwent inflatable and 404 (5.6%) semi-rigid PPI. Inflatable PPI was significantly associated with shorter length of hospital stay (difference of 2.2 days, 95%CI: 1.6-2.7, p < 0.001), lower odds of perioperative urinary tract infections (5.5% versus 9.2%; OR: 0.58, 95%CI: 0.41-0.84, p = 0.003) and surgical wound infections (1% versus 2.5%; OR: 0.42, 95%CI: 0.22-0.88, p = 0.012) compared to semi-rigid PPI. Overall, 4255 (62.4%) inflatable PPIs were undertaken in low- ( < 20 PPI/year) and 2563 (37.6%) in high-volume ( ≥ 20 PPI/year) centers. High-volume centers were significantly associated with shorter length of hospital stay (difference of 1.4 days, 95%CI: 1.2-1.7, p < 0.001) compared to low-volume centers. Our findings suggest that inflatable PPI leads to a shorter length of hospital stay and lower rates of perioperative urinary tract and surgical wound infections compared to semi-rigid PPI. Patients undergoing surgery in high-volume centers for inflatable PPI are discharged earlier from the hospital.

Penile fractures: the price of a merry Christmas.

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).

The Impact of Prostate Volume on the Prostate Imaging and Reporting Data System (PI-RADS) in a Real-World Setting.

Multiparametric magnetic resonance imaging (mpMRI) has emerged as a new cornerstone in the diagnostic pathway of prostate cancer. However, mpMRI is not devoid of factors influencing its detection rate of clinically significant prostate cancer (csPCa). Amongst others, prostate volume has been demonstrated to influence the detection rates of csPCa. Particularly, increasing volume has been linked to a reduced cancer detection rate. However, information about the linkage between PI-RADS, prostate volume and detection rate is relatively sparse. Therefore, the current study aims to assess the association between prostate volume, PI-RADS score and detection rate of csP-Ca, representing daily practice and contemporary mpMRI expertise. Thus, 1039 consecutive patients with 1151 PI-RADS targets, who underwent mpMRI-guided prostate biopsy at our tertiary referral center, were included. Prior mpMRI had been assessed by a plethora of 111 radiology offices, including academic centers and private practices. mpMRI was not secondarily reviewed in house before biopsy. mpMRI-targeted biopsy was performed by a small group of a total of ten urologists, who had performed at least 100 previous biopsies. Using ROC analysis, we defined cut-off values of prostate volume for each PI-RADS score, where the detection rate drops significantly. For PI-RADS 4 lesions, we found a volume > 61.5 ccm significantly reduced the cancer detection rate (OR 0.24; 95% CI 0.16-0.38; p < 0.001). For PI-RADS 5 lesions, we found a volume > 51.5 ccm to significantly reduce the cancer detection rate (OR 0.39; 95% CI 0.25-0.62; p < 0.001). For PI-RADS 3 lesions, none of the evaluated clinical parameters had a significant impact on the detection rate of csPCa. In conclusion, we show that enlarged prostate volume represents a major limitation in the daily practice of mpMRI-targeted biopsy. This study is the first to define exact cut-off values of prostate volume to significantly impair the validity of PI-RADS assessed in a real-world setting. Therefore, the results of mpMRI-targeted biopsy should be interpreted carefully, especially in patients with prostate volumes above our defined thresholds.

Absence of detrusor muscle in TUR-BT specimen - can we predict who is at highest risk?

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.

[Common errors, pitfalls, and management of complications of prostate biopsy : The most common diagnostic and procedural challenges of transrectal fusion prostate biopsy in the initial diagnosis of clinically significant prostate cancer]. / Häufige Fehler, "Pitfalls" und Komplikationsmanagement der Prostatabiopsie : Die häufigsten diagnostischen und prozeduralen Herausforderungen der transrektalen Fusionsbiopsie der Prostata bei Erstdiagnose eines klinisch signifikanten Prostatakarzinoms.

BACKGROUND: Transrectal (TR) prostate biopsy is the gold standard in diagnosis of prostate cancer (PC). It requires a precise and safe technique for sample acquisition. OBJECTIVE: Several approaches will be discussed to avoid overdiagnosis, false-negative results, and complications of the procedure. MATERIALS AND METHODS: We analyzed national and European guidelines, systematic reviews, meta-analyses, as well as prospective and retrospective studies to describe current trends in indication and performance of biopsies. RESULTS: Incorporation of risk calculators and magnetic resonance imaging (MRI) into daily routine reduces biopsy rates and results in a more precise diagnosis of clinically significant prostate cancer (csPC). Combination of random- and MRI-fusion guided biopsy-but also extending the radius of sampling by 10 mm beyond the MRI lesion and a transperineal (TP) sampling approach - lead to a higher tumor-detection rate. Bleeding is the most common complication after prostate biopsy and is usually self-limiting. Postbiopsy infection rates can be reduced through TP biopsy. CONCLUSION: TR MRI-fusion guided biopsy is a widely acknowledged tool in primary diagnostics of csPC. Higher detection rates and safety can be achieved through a TP sampling approach.

[Transrectal vs. transperineal fusion biopsy of the prostate : Time to switch to the perineal technique-comparison of methods and description of the transperineal procedure under local anesthesia]. / Transrektale vs. transperineale Fusionsbiopsie der Prostata : Zeit für einen Wechsel zur perinealen Technik ­ Vergleich der Methoden und Beschreibung des transperinealen operativen Vorgehens in Lokalanästhesie.

The clinical and histological diagnosis of prostate cancer is a crucial aspect of the routine work of a urologist. The high prevalence of multiresistant microorganisms leads to an increased incidence of sepsis after transrectal prostate biopsy. It requires a switch from the still gold-standard method to the transperineal fusion biopsy procedure after multiparametric prostate magnetic resonance imaging (MRI). This article provides an overview of the most important differences between the two methods and gives a detailed methodological description of transperineal fusion biopsy under local anesthesia.

Adverse Pathology after Radical Prostatectomy of Patients Eligible for Active Surveillance-A Summary 7 Years after Introducing mpMRI-Guided Biopsy in a Real-World Setting.

OBJECTIVE: Over the last decade, active surveillance (AS) of low-risk prostate cancer has been increasing. The mpMRI fusion-guided biopsy of the prostate (FBx) is considered to be the gold standard in preoperative risk stratification. However, the role of FBx remains unclear in terms of risk stratification of low-risk prostate cancer outside high-volume centers. The aim of this study was to evaluate adverse pathology after radical prostatectomy (RP) in a real-world setting, focusing on patients diagnosed with Gleason score (GS) 6 prostate cancer (PCa) and eligible for AS by FBx. SUBJECTS AND METHODS: Between March 2015 and March 2022, 1297 patients underwent FBx at the Department of Urology, Ludwig-Maximilians-University of Munich, Germany. MpMRI for FBx was performed by 111 different radiology centers. FBx was performed by 14 urologists from our department with different levels of experience. In total, 997/1297 (77%) patients were diagnosed with prostate cancer; 492/997 (49%) of these patients decided to undergo RP in our clinic and were retrospectively included. Univariate and multivariable logistic regression analyses were performed to evaluate clinical and histopathological parameters associated with adverse pathology comparing FBx and RP specimens. To compare FBx and systematic randomized biopsies performed in our clinic before introducing FBx (SBx, n = 2309), we performed a propensity score matching on a 1:1 ratio, adjusting for age, number of positive biopsy cores, and initial PSA (iPSA). RESULTS: A total of 492 patients undergoing FBx or SBx was matched. In total, 55% of patients diagnosed with GS 6 by FBx were upgraded to clinically significant PCa (defined as GS ≥ 7a) after RP, compared to 52% of patients diagnosed by SBx (p = 0.76). A time delay between FBx and RP was identified as the only correlate associated with upgrading. A total of 5.9% of all FBx patients and 6.1% of all SBx patients would have been eligible for AS (p > 0.99) but decided to undergo RP. The positive predictive value of AS eligibility (diagnosis of low-risk PCa after biopsy and after RP) was 17% for FBx and 6.7% for SBx (p = 0.39). CONCLUSIONS: In this study, we show, in a real-world setting, that introducing FBx did not lead to significant change in ratio of adverse pathology for low-risk PCa patients after RP compared to SBx.

[Special diagnostics in pediatric urology-Ultrasound, VCUG, CT and MRI : Part 1: tips for the practice]. / Spezielle Diagnostik in der Kinderurologie ­ konventionelle und spezielle Sonographie, MCU, CT und MRT : Teil 1: Tipps für die Praxis.

The diagnostics and treatment of pediatric urology patients in the clinical routine can be extremely challenging. In comparison to adult patients, congenital diseases, more time consuming examinations and limited options in addition to the parents' expectations must be taken into account in the diagnostic work up. In this first of two parts we will delve into ultrasound diagnostics as the cornerstone in the diagnostic pathway of children with hydronephrosis ans take a closer look on contrast enhanced ultrasound (CEUS). Conventional voiding cystourethrography still plays a major role in the diagnostic pathway of vesicoureteric reflux and will be treated in this article. Computed tomography should only be considered in pediatric patients in rare cases, always taking radiation into critical account. Magnetic resonance imaging provides an excellent anatomical overview without exposing the child to unnecessary radiation. This article provides an overview on the diagnostic imaging studies in pediatric urology and brings tips for the diagnostic evaluation.

[Special diagnostics in pediatric urology-Nuclear medicine diagnostics, advanced diagnostics for bladder voiding disorders and imaging diagnostics in the operating room : Tips for the practice part 2]. / Spezielle Diagnostik in der Kinderurologie ­ Nuklearmedizinische Diagnostik, weiterführende Diagnostik bei Blasenentleerungsstörungen und bildgebende Diagnostik im OP : Teil 2: Tipps für die Praxis.

The diagnostics and treatment of pediatric urology patients in the clinical routine can be extremely challenging. In contrast to adult patients, the main concerns in the diagnostics of congenital diseases are time consuming examinations and limited options in addition to the expectations of the parents. The exact knowledge of the diagnostic possibilities in association with the correct interpretation of the indications is essential. Simple processes can be much more time consuming because of a lack of compliance, especially in very young children. Sonography is considered the standard for imaging in pediatric urology. Profound knowledge of the embryonal development and also physiological processes throughout childhood contribute to making the correct diagnosis. This article deals with the possibilities of nuclear medicine diagnostics, advanced diagnostics in bladder voiding disorders and finally imaging diagnostics in the pediatric urological operating room.

Asymptomatic bacteriospermia and infertility-what is the connection?

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.

Long-term Health-related Quality of Life (HRQOL) After Radical Cystectomy and Urinary Diversion - A Propensity Score-matched Analysis.

INTRODUCTION: Radical cystectomy (RC) and urinary diversion by ileal conduit (IC) or ileal orthotopic neobladder (ONB) is the standard-of-care for surgical treatment of muscle-invasive bladder cancer. Yet, it is unclear how urinary diversion affects the patient's health-related quality of life (HRQOL) in the longer-term. METHODS: HRQOL was assessed preoperatively, 3mo postoperatively and then annually until a maximum follow-up of 48 months using the validated EORTC QLQ-C30- as well as the bladder cancer-specific FACT-BL- and QLQ-BLM30-questionnaires. A propensity-score matching for the variables "age," "ASA-classification," "cardiovascular co-morbidity," "sex" as well as "tumor stage," and "preoperative physical functioning score" was performed. Hypothetical predictors for decreased general HRQOL were analyzed using multivariable logistic regression models. RESULTS: After propensity-score matching, 246 patients were analyzed. HRQOL assessment revealed significant differences regarding preoperative QLQ-C30 symptoms which diminished during the postoperative time course. Similarly, we did not find significant differences based on bladder cancer-specific FACT-BL and QLQ-BLM HRQOL assessment including body image (48 months: 29.6.4 [IC] vs. 40.7 [ONB]; P = .733). Regarding general HRQOL, we found increased global health status scores for ONB throughout the whole observational period without reaching statistical significance (48 months: 55.0 [IC] vs. 70.1 [ONB]; P = .079). In multivariate analysis, cardiovascular comorbidity was an independent predictor of impaired HRQOL 24 months (HR 2.20; CI95% 1.02-5.72, P = .044) and 36 months (HR 6.84; CI95% 1.61-29.14, P = .009) postoperatively. CONCLUSION: We did not observe significant differences in bladder-specific as well as generic HRQOL in the longer-term and consequently, the type of urinary diversion was not an independent predictor of good general HRQOL in a follow-up period of 4 years.

Prognostic Value of Pretreatment Inflammatory Markers in Patients Receiving Radical Cystectomy for Urothelial Bladder Cancer: Does Age Matter?

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.

Computed-tomography based scoring system predicts outcome for clinical lymph node-positive patients undergoing radical cystectomy

ABSTRACT 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.

Computed-tomography based scoring system predicts outcome for clinical lymph node-positive patients undergoing radical cystectomy.

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.

Impact of bacillus Calmette-Guerin intravesical therapy on the diagnostic efficacy of The Paris System for Reporting Urinary Cytology in patients with high-grade bladder cancer.

BACKGROUND: In high-grade urothelial carcinoma (UC) of the bladder, bacillus Calmette-Guerin (BCG) therapy is a therapeutic mainstay, and urinary cytology is recommended to detect recurrences. However, intravesical BCG instillations can induce morphologic changes in urothelial cells. The authors investigated the impact of BCG therapy on the efficacy of urinary cytology. METHODS: Matched pathology and cytology samples from patients undergoing transurethral resection of the bladder after BCG therapy were assessed. Cytology samples were graded according to The Paris System for Reporting Urinary Cytology. Diagnostic quality criteria were tested for different cutoff definitions, and the results were compared between those obtained <100 versus ≥100 days after the last BCG instillation. In addition, the oncologic outcome of false-positive results was assessed. RESULTS: In total, 389 matched cases from 197 patients who had a history of high-grade UC (HGUC) were identified. Sixty cases (15.7%) were diagnosed as high-grade urothelial bladder cancer. The cytology diagnoses were as follows: non-HGUC, 191 cases (49.1%); atypical urothelial cells, 80 cases (20.6%); suspicious for HGUC, 56 cases (14.4%); and HGUC, 56 cases (14.4%). Interrater reliability was substantial (κ = 0.660). Sensitivity increased from 45% to 75% when cases diagnosed as suspicious for HGUC were also counted as positive. Notably, sensitivity was reduced within the first 100 days after BCG therapy (61.9%) compared with sensitivity at longer intervals (82.1%). Reactive atypia (odds ratio, 4.155; 95% confidence interval, 2.136-8.085; P < .001) and cellular degeneration (odds ratio, 5.050; 95% CI, 2.094-12.175; P < .001) of urothelial cells were associated with false-positive rates, and 44.7% of patients who had a false-positive cytology classification presented with HGUC during follow-up. CONCLUSIONS: BCG therapy has a short-term adverse impact on the efficacy of urinary cytology. After BCG therapy, cases classified as suspicious for HGUC should be considered positive. Importantly, patients with false-positive cytology findings should be closely monitored.
