ABSTRACT

INTRODUCTION AND OBJECTIVES: Decision-making to perform prostate biopsy should include individual risk assessment. Patients classified as low risk by the Rotterdam Prostate Cancer Risk Calculator are advised to forego biopsy (PBx). There is concern about missing clinically significant prostate cancer (csPCa). A clear pathway for follow-up is needed. MATERIAL AND METHODS: Data for 111 consecutive patients were collected. Patients were encouraged to adhere to a PSA-density-based safety net after PBx was omitted. Cut off values indicating a re-evaluation were PSA density >0.15 ng/mL/ccm in PBx-naïve patients and >0.2 ng/mL/ccm in men with past-PBx. Primary endpoint was whether men had their PSA taken regularly. Secondary endpoint was whether a new multiparametric MRI was performed when PSA-density increased. Tertiary endpoint was whether biopsy was performed when risk stratification revealed an increased risk. RESULTS: Median follow-up was 12 months (IQR 9-15 months). The primary endpoint was reached by 97.2% (n = 106). The secondary endpoint was reached by 30% (n = 3). The tertiary endpoint was reached by 50% (n = 2). Histopathologic analyses revealed csPCa in none of these cases. Risk stratification did not change (p = 0.187) with the majority of patients (89.2%, n = 99). CONCLUSION: The concern of missing csPCa when omitting PBx in the risk-stratified pathway may be negated. Changes in risk stratification during follow-up should lead to subsequent PBx. We suggest implementing a safety net based on PSA density and digital rectal examination (DRE).

ABSTRACT

BACKGROUND: Magnetic resonance imaging (MRI)-targeted prostate biopsy is a routinely used diagnostic tool for prostate cancer (PCa) detection. However, a clear superiority of the optimal approach for software-based MRI processing during biopsy procedures is still unanswered. To investigate the impact of robotic approach and software-based image processing (rigid vs. elastic) during MRI/transrectal ultrasound (TRUS) fusion prostate biopsy (FBx) on overall and clinically significant (cs) PCa detection. METHODS: The study relied on the instructional retrospective biopsy data collected data between September 2013 and August 2017. Overall, 241 men with at least one suspicious lesion (PI-RADS ≥ 3) on multiparametric MRI underwent FBx. The study protocol contains a systematic 12-core sextant biopsy plus 2 cores per targeted lesion. One experienced urologist performed 1048 targeted biopsy cores; 467 (45%) cores were obtained using rigid processing, while the remaining 581 (55%) cores relied on elastic image processing. CsPCa was defined as International Society of Urological Pathology (ISUP) grade ≥ 2. The effect of rigid versus elastic FBx on overall and csPCa detection rates was determined. Propensity score weighting and multivariable regression models were used to account for potential biases inherent to the retrospective study design. RESULTS: In multivariable regression analyses, age, prostate-specific antigen (PSA), and PIRADS ≥ 3 lesion were related to higher odds of finding csPCa. Elastic software-based image processing was independently associated with a higher overall PCa (odds ratio [OR] = 3.6 [2.2-6.1], p < 0.001) and csPCa (OR = 4.8 [2.6-8.8], p < 0.001) detection, respectively. CONCLUSIONS: Contrary to existing literature, our results suggest that the robotic-driven software registration with elastic fusion might have a substantial effect on PCa detection.

ABSTRACT

PURPOSE: This study aimed to evaluate psychosocial distress in the context of continence and oncological outcome during the early recovery period after radical prostatectomy (RP) for prostate cancer. PATIENTS AND METHODS: Retrospectively collected data from 587 patients who underwent inpatient rehabilitation after RP in 2016 and 2017 were analyzed. Psychosocial distress (measured by using a Questionnaire on Stress in Cancer Patients [QSC-R10]) and continence status (urine loss on a 24-h pad test and urine volume on uroflowmetry) were evaluated at the beginning (T1) and end (T2) of a 3-week inpatient rehabilitation. Multivariate logistic regression was performed to identify predictors for high distress (QSC-R10 score ≥15). RESULTS: The median patient age was 65 years. At the start of rehabilitation, 204 patients (34.8%) demonstrated high distress. Psychosocial distress decreased significantly (p < 0.001) from a median of 11.0 at T1 (median 16 days after surgery) to a median of 6.0 at T2 (median 37 days after surgery). Complete continence increased significantly (p < 0.001) from 39.0% at T1 to 58.9% at T2. The median urine volume increased significantly (p < 0.001) from 161 mL at T1 to 230 mL at T2. Often, distress is higher in younger patients, whereas incontinence is higher in older patients. Multivariate logistic regression analysis identified age ≤69 years (p = 0.001) and tumor stage ≥pT3 (p = 0.006) as independent predictors of high distress. CONCLUSIONS: Distress and incontinence decreased significantly during the 3 weeks of inpatient rehabilitation after RP. Patient age ≤69 years and tumor stage ≥pT3 are independent predictors of high psychosocial distress.

ABSTRACT

INTRODUCTION: This study aimed to investigate the number of cores needed in a systematic biopsy (SB) in men with clinical suspicion of prostate cancer (PCa) but negative prebiopsy multiparametric magnetic resonance imaging and to test prostate-specific antigen (PSA) density as an indicator for reduced SB. METHODS: Two hundred and seventy-four patients were analyzed, extracted from an institutional database. Detection rates of any PCa and clinically significant (CS) PCa for different reduced biopsy protocols were compared by using Fisher's exact test. RESULTS: In total, 12-core SB revealed PCa in 103 (37.6%) men. Detection rates of reduced biopsy protocols were 74 (27%, 6-core) and 82 (29.9%, 8-core). Regarding CSPCa, 12-core SB revealed a detection rate of 26 (9.5%). Reduced biopsy protocols detected less CSPCa: 15 (5.5%) and 18 (6.6%), respectively. All differences were statistically significant, p < 0.05. PSA density ≥0.15 did not help to filter out men in whom a reduced biopsy may be sufficient. CONCLUSIONS: Twelve-core SB still has the highest detection rate of any PCa and CSPCa compared to reduced biopsy protocols. If the investigator and patient agree - based on individual risk calculation - to perform a biopsy, this SB should contain at least 12 cores regardless of PSA density.

ABSTRACT

INTRODUCTION: The risk of occult prostate carcinoma (PCa) after negative multiparametric MRI (mpMRI)-transrectal fusion biopsy (F-Bx) is unknown. To determine the false-negative predictive value, we examined PCa detection after prior negative F-Bx. METHODS: Between December 2012 and November 2016, 491 patients with suspected PCa and suspicious mpMRI findings underwent transrectal F-Bx. Patients with benign pathology (n = 191) were eligible for our follow-up (FU) survey. Patient characteristics and clinical parameters were correlated to subsequent findings of newly detected PCa. RESULTS: Complete FU with a median of 31 (interquartile range: 17-39) months was available for 176/191 (92.2%) patients. Of those, 54 men had either surgical interventions on the prostate or re-Bxs. Newly detected PCa was evident in 14/176 (7.95%) patients stratified to ISUP ≤2 in 10 and ≥3 in 4 cases. The comparison of patients with newly detected PCa to those without cancerous findings in FU showed significant differences in prostate-specific antigen (PSA) density (0.16 vs. 0.13 ng/mL2) and prostate volume (45 vs. 67 mL, both p < 0.05). Both factors are significant predictors for newly detected cancer after initial negative F-Bx. CONCLUSION: Only PSA density (>0.13 ng/mL2) and small prostate volume are significant predictors for newly detected PCa after initial negative F-Bx. Despite negative mpMRI/TRUS F-Bx results, patients should be further monitored due to a risk of developing PCa over time. Notwithstanding the limitation of our study that not all patients underwent another Bx, we assume that the false-negative rate is low but existing. Our data represent a real-world scenario.

ABSTRACT

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic is disrupting urology health-care worldwide. Reduced emergency room visits resulting in adverse outcomes have most recently been reported in pediatrics and cardiology. We aimed to compare patients with emergency room visits for pyelonephritis in 2019 (pre-COVID-19 era) and within the first wave of pandemic in 2020 (COVID-19 era) with regard to the number of visits and severe adverse disease outcomes. METHODS: We performed a retrospective multicentre study comparing characteristics and outcomes of patients with pyelonephritis, excluding patients with hydronephrosis due to stone disease, in 10 urology departments in Germany during a 1-month time frame in March and April in each 2019 and 2020. RESULTS: The number of emergency room visits for pyelonephritis in the COVID-19 era was lower (44 patients, 37.0%) than in the pre-COVID-19 era (76 patients, 63.0%), reduction rate: 42.1% (p = 0.003). Severe adverse disease outcome was more frequent in the COVID-19 era (9/44 patients, 20.5%) than in the pre-COVID-19 era (5/76 patients, 6.6%, p = 0.046). In detail, 7 versus 3 patients needed monitoring (15.9 vs. 3.9%), 2 versus no patients needed intensive-care treatment (4.5 vs. 0%), 2 versus no patients needed drain placement (4.5 vs. 0%), 2 versus no patients had a nephrectomy (4.5 vs. 0%), and 2 versus 1 patient died (4.5 vs. 1.3%). CONCLUSION: This report of collateral damage during CO-VID-19 showed that emergency room visits were decreased, and severe adverse disease outcomes were increased for patients with pyelonephritis in the COVID-19 era. Health authorities should set up information campaign programs actively encouraging patients to utilize emergency room services in case of severe symptoms specifically during the actual second wave of pandemic.

ABSTRACT

Histopathological differentiation between severe urocystitis with reactive urothelial atypia and carcinoma in situ (CIS) can be difficult, particularly after a treatment that deliberately induces an inflammatory reaction, such as intravesical instillation of Bacillus Calmette-Guèrin. However, precise grading in bladder cancer is critical for therapeutic decision making and thus requires reliable immunohistochemical biomarkers. Herein, an exemplary potential biomarker in bladder cancer was identified by the novel approach of Fourier transform infrared imaging for label-free tissue annotation of tissue thin sections. Identified regions of interest are collected by laser microdissection to provide homogeneous samples for liquid chromatography-tandem mass spectrometry-based proteomic analysis. This approach afforded label-free spatial classification with a high accuracy and without interobserver variability, along with the molecular resolution of the proteomic analysis. Cystitis and invasive high-grade urothelial carcinoma samples were analyzed. Three candidate biomarkers were identified and verified by immunohistochemistry in a small cohort, including low-grade urothelial carcinoma samples. The best-performing candidate AHNAK2 was further evaluated in a much larger independent verification cohort that also included CIS samples. Reactive urothelial atypia and CIS were distinguishable on the basis of the expression of this newly identified and verified immunohistochemical biomarker, with a sensitivity of 97% and a specificity of 69%. AHNAK2 can differentiate between reactive urothelial atypia in the setting of an acute or chronic cystitis and nonmuscle invasive-type CIS.

ABSTRACT

INTRODUCTION: There are limited data on the learning curve of magnetic resonance imaging/transrectal ultrasound (MRI/TRUS)-fusion targeted prostate biopsies (tBx). OBJECTIVE: The aim of this study was to investigate the difference in prostate cancer (PCa) detection rate between an experienced urologist and novice resident performing tBx. METHODS: A total of 183 patients underwent tBx from 2012 to 2016 for a total of 518 tBx cores. Biopsies in this study were performed by an experienced urologist (investigator A) or a novice resident (investigator B). The outcome was the detection of PCa on tBx. Using a multivariable logistic regression model, we estimated odds ratios for the detection of PCa. Inverse probability treatment weighting (IPTW) was used to balance patients' baseline characteristics and compare detection rates of PCa. Before performance of tBx, all patients underwent MRI. RESULTS: On multivariable logistic regression analysis, investigator experience was associated with a higher odds of detection of PCa (OR = 1.003; 95% confidence interval 1.002-1.006, p = 0.037). After IPTW adjustment, there was no significant difference between the detection rate of investigator A (23%) and investigator B (32%; p = 0.457). CONCLUSIONS: Data revealed a positive association between investigator experience and the odds of PCa detection, although there was no difference in the detection rates of the investigators.

ABSTRACT

PURPOSE: We sought to identify facility level variation in the use of definitive therapy among men diagnosed with clinically localized, low risk prostate cancer who were more than 65 years old and had a limited life expectancy of less than 10 years. MATERIALS AND METHODS: Using data from the National Cancer Database we identified 18,178 men older than 65 years with less than a 10-year life expectancy receiving definitive therapy at a total of 1,172 facilities for biopsy confirmed localized, low risk prostate cancer diagnosed between January 2004 and December 2013. A multilevel, hierarchical, mixed effects logistic regression model was fitted to predict the odds of receiving definitive therapy. RESULTS: Overall 18,178 men (76%) older than 65 years with limited life expectancy and a diagnosis of low risk prostate cancer received definitive therapy, although the rate of therapy decreased significantly with time (p <0.001). Patients receiving definitive therapy were more often younger (80 years or older vs 66 to 69 years OR 0.12, 95% CI 0.09-0.15, p <0.001) and white rather than black (OR 0.86, 95% CI 0.75-0.98, p = 0.03). Conversely, being uninsured (OR 0.37, 95% CI 0.21-0.63, p <0.001) and receiving care at an academic medical center (OR 0.36, 95% CI 0.28-0.46, p <0.001) conferred decreased odds of undergoing definitive therapy. The proportion of men undergoing definitive therapy ranged from 0.12% to 100% across facilities. CONCLUSIONS: We found significant facility level variation in rates of definitive therapy in men with localized prostate cancer and limited life expectancy. Health care providers and policy makers alike should be aware of the varying frequency with which this potentially low value service is performed.

ABSTRACT

PURPOSE: In this study, we sought to describe the contemporary trends in utilization of neoadjuvant androgen deprivation therapy (ADT). As a secondary endpoint, we assessed the community-level effect of neoadjuvant ADT on positive surgical margins after radical prostatectomy (RP). METHODS: Using the National Cancer Database (2004-2014), we identified patients with clinically localized prostate cancer (PCa) [cT1-4N0M0] treated with RP. The estimated annual percentage change (EAPC) mixed linear regression methodology was used for temporal trend analysis of neoadjuvant ADT. Observed differences in baseline characteristics between patients treated with neoadjuvant ADT versus those who were not were then controlled for using an inverse probability of treatment weighting (IPTW) approach. IPTW-adjusted analyses were then performed to examine the odds of positive surgical margins. RESULTS: Overall, 8184 (2.12%) and 377,843 (97.88%) individuals with PCa were treated with neoadjuvant ADT prior to RP versus RP only, respectively. There was a consistent trend in decreasing use of neoadjuvant ADT over time, with a nadir observed in 2011 [EAPC - 8.08; 95% confidence interval (CI) - 11.7 to - 4.32; p < 0.05]. In IPTW-adjusted analyses, the odds of positive surgical margins were lower in patients receiving neoadjuvant ADT with low-risk [odds ratio (OR) 0.65; 95% CI 0.51-0.84; p < 0.001] and intermediate-risk [OR 0.76; 95% CI 0.69-0.85; p < 0.001] PCa. CONCLUSIONS: After a period of steady decline, there appears to be a modest trend towards increased utilization of neoadjuvant ADT in more recent years. We found an association between neoadjuvant ADT and decreased odds of positive surgical margins among low- and intermediate-risk patients.

ABSTRACT

Testicular cancer has excellent cure rates; however, poor guideline adherence can lead to inappropriate management, with a detrimental effect on outcomes. Therefore, we aimed to investigate the current patterns of care for testicular cancer patients and to evaluate guideline adherence. A 19-item survey was distributed among German urologists between September 2015 and September 2016. The response rate was 45% (411/920). Staging imaging of the chest was performed by computed tomography (CT) in 85.5% and X-ray in 17.7%, and for the abdomen, by CT in 83.7% and by magnetic resonance imaging (MRI) in 21.1%. Areas of discrepancy with respect to guideline recommendations included underuse of MRI and infrequent follow-up examinations for changes in the cardiovascular, endocrine, neurological, and pulmonary systems, in addition to psychological burden. Further deviations of reported routine procedures from guideline recommendations were identified in the fields of active surveillance in Stage I seminoma, contralateral biopsies (63.1% overuse) and cryopreservation (19.2% underuse). Moreover, we found that hospital-based clinicians and younger specialists, with ≤5 years of practice following board certification, perform a more accurate and thorough follow-up. German urologists show relatively strong guideline adherence in staging patterns. Significant improvements are necessary in the following areas: recommending cryopreservation, imaging modalities and accurate follow-up examinations with a focus on late toxicities.

ABSTRACT

PURPOSE: Androgen deprivation therapy is associated with the development of diabetes and metabolic syndrome. To our knowledge its effect on the development of nonalcoholic fatty liver disease, a condition which frequently co-occurs with metabolic syndrome and other subsequent liver conditions such as liver cirrhosis, hepatic necrosis or any liver disease, has not been investigated. MATERIALS AND METHODS: We identified 82,938 men 66 years old or older who were diagnosed with localized prostate cancer in the SEER (Surveillance, Epidemiology and End Results)-Medicare database from 1992 to 2009. Men with preexisting nonalcoholic fatty liver disease, liver disease, diabetes or metabolic syndrome were excluded from study. Propensity score adjusted, competing risk regression models were created to compare the risk of nonalcoholic fatty liver disease in men who were vs were not treated with androgen deprivation. We also explored the influence of cumulative exposure to androgen deprivation therapy, calculated as monthly equivalent doses of gonadotropin-releasing hormone agonists/antagonists (fewer than 7, 7 to 11 or more than 11 doses). RESULTS: Overall 37.5% of men underwent androgen deprivation therapy. They were more likely to be diagnosed with nonalcoholic fatty liver disease (HR 1.54, 95% CI 1.40-1.68), liver cirrhosis (HR 1.35, 95% CI 1.12-1.60), liver necrosis (HR 1.41, 95% CI 1.15-1.72) and any liver disease (HR 1.47, 95% CI 1.35-1.60). A dose-response relationship was observed between the number of androgen deprivation therapy doses, and nonalcoholic fatty liver disease and any liver disease. CONCLUSIONS: Androgen deprivation therapy in men with prostate cancer is associated with the diagnosis of nonalcoholic fatty liver disease. The usual limitations of an observational study design apply, including possible inaccuracy in defining outcomes in a population based registry.

ABSTRACT

OBJECTIVES: To evaluate the effect of peri-operative blood transfusion (PBT) on recurrence-free survival, overall survival, cancer-specific mortality and other-cause mortality in patients undergoing radical cystectomy (RC), using a contemporary European multicentre cohort. PATIENTS AND METHODS: The Prospective Multicentre Radical Cystectomy Series (PROMETRICS) includes data on 679 patients who underwent RC at 18 European tertiary care centres in 2011. The association between PBT and oncological survival outcomes was assessed using Kaplan-Meier, Cox regression and competing-risks analyses. Imbalances in clinicopathological features between patients receiving PBT vs those not receiving PBT were mitigated using conventional multivariable adjusting as well as inverse probability of treatment weighting (IPTW). RESULTS: Overall, 611 patients had complete information on PBT, and 315 (51.6%) received PBT. The two groups (PBT vs no PBT) differed significantly with respect to most clinicopathological features, including peri-operative blood loss: median (interquartile range [IQR]) 1000 (600-1500) mL vs 500 (400-800) mL (P < 0.001). Independent predictors of receipt of PBT in multivariable logistic regression analysis were female gender (odds ratio [OR] 5.05, 95% confidence interval [CI] 2.62-9.71; P < 0.001), body mass index (OR 0.91, 95% CI 0.87-0.95; P < 0.001), type of urinary diversion (OR 0.38, 95% CI 0.18-0.82; P = 0.013), blood loss (OR 1.32, 95% CI 1.23-1.40; P < 0.001), neoadjuvant chemotherapy (OR 2.62, 95% CI 1.37-5.00; P = 0.004), and ≥pT3 tumours (OR 1.59, 95% CI 1.02-2.48; P = 0.041). In 531 patients with complete data on survival outcomes, unweighted and unadjusted survival analyses showed worse overall survival, cancer-specific mortality and other-cause mortality rates for patients receiving PBT(P < 0.001, P = 0.017 and P = 0.001, respectively). After IPTW adjustment, those differences no longer held true. PBT was not associated with recurrence-free survival (hazard ratio [HR] 0.92, 95% CI 0.53-1.58; P = 0.8), overall survival (HR 1.06, 95% CI 0.55-2.05; P = 0.9), cancer-specific mortality (sub-HR 1.09, 95% CI 0.62-1.92; P = 0.8) and other-cause mortality (sub-HR 1.00, 95% CI 0.26-3.85; P > 0.9) in IPTW-adjusted Cox regression and competing-risks analyses. The same held true in conventional multivariable Cox and competing-risks analyses, where PBT could not be confirmed as a predictor of any given endpoint (all P values >0.05). CONCLUSION: The present results did not show an adverse effect of PBT on oncological outcomes after adjusting for baseline differences in patient characteristics.

ABSTRACT

AIMS: To examine the impact of Salvage lymph node dissection (SLND) on bladder function and oncological outcome in hormone naïve patients with nodal recurrence of prostate cancer (PCa) after radical prostatectomy (RP). METHODS: In a prospective study between October 2015 and November 2016, 20 patients underwent transperitoneal SLND for nodal recurrence of PCa after RP at our institution. Standardized urodynamics were performed pre- and postoperatively after 6 weeks, 3, and 6 to 12 months. Prostate-specific antigen (PSA) levels were used to monitor the oncological outcome. Perioperative outcomes encompassed, among others, type of complications after surgery classified to Clavien-Dindo. RESULTS: The proportion of patients with neurogenic bladder dysfunction was postoperative at 6 weeks, 3, and 6 to 12 months 78.5%, 70%, and 45.5%, respectively. Compared to preoperative urodynamics, follow-ups revealed a statistical significant cleavage of bladder wall compliance until six to twelve months after SLND (34.5 vs 22 mL/cmH2 O, P = 0.044). Referring to the oncological outcome all patients experienced a PSA progression, 10 patients (50%) within 11 weeks after surgery. Overall, four patients (20%) suffered from a postoperative complication after SLND, which comprises Clavien grade I-IIIa. CONCLUSIONS: Transperitoneal SLND, as a treatment option for patients with nodal recurrence of PCa after RP reveals additional potential pitfalls than previously reported. Urodynamics reveal a significant impact of SLND on postoperative functional bladder dysfunctions. Therefore, informed consent prior to SLND should include the risk of persistent low compliance bladder.

ABSTRACT

OBJECTIVES: To determine whether short-term stenting using an external ureter catheter following ureterorenoscopic stone extraction provides a better outcome in comparison to double-J stent ureteral stenting. METHODS: Between August 2014 and August 2015, 141 patients initially managed with a double-J stent insertion were prospectively randomized to ureter catheter for 6 h vs double-J stent insertion for 5 days after stone extraction via ureteroscopy retrograde surgery (including flexible ureteroscopy retrograde surgery) in a single academic center. Endoscopic procedures were performed by nine surgeons. Exclusion criteria were acute urinary tract infection, a solitary kidney, or a stone mass more than 25 mm. Study endpoints were ureter-stent related symptoms and pain assessed by a validated questionnaire (ureteral stent symptom questionnaire) and visual analogue scale before and 4 weeks after surgery. RESULTS: Overall stone-free rate was more than 90%. Mean operative time was 24 min (range 5-63). Groups did not differ in terms of age, body mass index, and stone size. Patients who received short-term ureter catheter showed a significantly higher quality of life. In the ureter catheter group, the urinary index score (16.8 vs 27.8; P < 0.0001), the pain score (9.7 ± 1.3 vs 20.2 ± 1.5; P < 0.0001), and general health index (15.3 ± 0.7 vs 8.5 ± 0.6; P < 0.0001) were significantly lower. Consultation of a physician and antibiotic treatment were rarely needed (1.3 ± 0.1 vs 1.6 ± 0.1; P = 0.017). CONCLUSION: A short-term ureter catheter insertion for 6 h following ureteroscopy retrograde surgery stone removal is a safe procedure and superior to double-J stent insertion with regard to urinary symptoms, pain, quality of life, and stent related symptoms. Patients treated with a short-term ureter catheter recover more quickly, return to work earlier, and need less doctor visits. Most patients would recommend a ureter catheter, and would prefer this strategy in case of future stone treatments.

ABSTRACT

PURPOSE: To examine postoperative complications after radical cystectomy (RC) and creation of an ileum conduit (IC) or a neobladder (NB), and to identify preoperative risk factors in a contemporary series of bladder cancer patients. PATIENTS AND METHODS: The study relied on prospectively collected data for 842 patients, who underwent inpatient rehabilitation (IR) after RC and urinary diversion (IC n = 447, NB n = 395) between April 2018 and December 2019. Postoperative complications until the end of IR were assessed according to the Clavien-Dindo classification. Uni- and multivariate analyses were performed to identify predictors for complications. RESULTS: A total of 2689 complications occurred in 813 patients (96.6%). High-grade complications occurred more frequently before IR onset (25.5% vs. 5.7%; P < .001), whereas a higher percentage of low-grade complications occurred during IR (89.0% vs. 77.8%; P < .001). The most common complication categories were genitourinary (60.9%), infectious (54.0%) and gastrointestinal (49.2%). Rates of high-grade complications do not differ between IC and NB patients (26.8% vs. 31.6%, P = .126). Independent predictors for overall complications were NB (odds ratio [OR] 21.520; P < .001), age ≥70 years (OR 2.522; P = .027) and higher body mass index (OR 1.153, P = .008). Risk factors for high-grade complications were NB (OR 1.448; P = .039) and Charlson Comorbidity Index ≥2 (OR 1.999; P = .001). Hospital readmission rate was 9.4%. CONCLUSION: Our study revealed significantly higher overall and high-grade complication rates after RC with IC or NB creation than previously published. A high percentage of low-grade complications occur after hospital discharge. The hospital readmission rate was lower compared to historical data.

ABSTRACT

BACKGROUND: Several international medical societies reported a negative impact on urology residency training programs due to the COVID-19 pandemic. OBJECTIVES: The aim of this study was to investigate the impact of the pandemic on urological residency in Germany. MATERIALS AND METHODS: From the 20th of May 2020 until the 20th of June 2020, a Germany-wide online survey on the continuing residency training was distributed via the members of the working group, social media (Facebook, Twitter, Instagram) and the German Society of Residents in Urology (GeSRU e.V.) newsletter. The survey covered 3 topics: 1) basic characteristics of the participants, 2) general and 3) subjective influence of the COVID-19 pandemic on clinics and further residency training. RESULTS: A total of 50 residents took part in the survey; 54% were women. The median age was 31 years. Most of the participants were in their 2nd (22%) and 5th (26%) year of training and worked in a university hospital (44%) or in a clinic of maximum care (30%). 38% of the respondents stated that they only served urological emergencies during the COVID-19 pandemic. For 28% this meant a very large delay (80-100%) in the specialisation, while 28% stated only a minor impact. 66% documented training impairments caused by fewer operations, low patient numbers in the outpatient department (50%), congress (50%) and workshop (44%) cancellations. 46% of residents reported direct contact with COVID-19 patients while 10% were deployed on interdisciplinary IMC units. Numerous physical distancing and hygiene measures have been implemented by the clinics. CONCLUSION: On average, around 50% of the urology residents indicated significant restrictions in training due to the COVID-19 pandemic in Germany. The delay in training cannot currently be measured in units of time, but it can be assumed that training for residents during the pandemic is likely to be of a lower quality compared to previous generations.
