Robotic surgery of the urothelial carcinoma of the upper urinary tract single surgeon initial experience, 66 consecutive cases.

PURPOSE: Robotic surgery is increasingly utilized in the treatment of urothelial carcinoma of the upper urinary tract (UTUC). This study investigates the advantages and burden of robot-assisted surgical treatment of the urothelial carcinoma of the upper urinary tract in a referral urological department, along with their functional and oncological results. METHODS: The study included 66 prospectively enrolled patients who were surgically treated by a single, robotically specialized surgeon between July 2019 and December 2023. Patients were divided into three groups. Group 1: 50 patients underwent robot-assisted radical Nephroureterectomy (RANU) with bladder cuff excision, Group 2: 11 patients underwent RANU simultaneously with robot-assisted radical cystectomy (RARC), and Group 3: 5 patients underwent robot-assisted segmental ureterectomy (RASU). Clinical and oncological parameters were compared. Perioperative morbidity according to Clavien-Dindo was the primary endpoint of our study. The secondary endpoint was oncologic outcomes. RESULTS: 37.8% of patients had locally advanced carcinomas. The average console time of RANU with bladder cuff excision was 69 min. The rate of positive surgical margins was n = 1/66 (2%). Lymphadenectomy (LAD) was performed on 30% of patients, with a mean of 13.7 lymph nodes removed. Of those who received LAD, 33% had lymph node metastasis. n = 6/66 (9%) patients received blood transfusion. The overall complication rate was 24%. The readmission rate was 7.5%. With a median follow-up of 26 months, the 2-year recurrence-free survival rate was 84.4%, and the 2-year overall survival rate was 94%. CONCLUSION: Robotic surgery is a feasible option for treating UTUC that can be adapted to meet the surgical needs of each patient. Prospective studies are warranted to confirm its benefits.

On the relationship between various anticoagulants and robot-assisted radical prostatectomy: a single-surgeon serial analysis.

Prostate cancer patients often have other health conditions and take anticoagulants. It was believed that surgery under anticoagulants could worsen surgical results. This study aims to explore the safety of robot-assisted prostatectomy in anticoagulated patients, without any exclusion criteria. The study included 500 patients who underwent RARP by a single surgeon between April 2019 and August 2022. Patients were divided into two groups: Group 1, consisting of 376 men (75.2%), did not receive any anticoagulation, while Group 2, with 124 patients (24.8%), received different forms of anticoagulation. Then, the anticoagulation group was divided into 4 subgroups according to their definite anticoagulation: the aspirin 15.6%, new oral anticoagulants (NOAC) 5.4%, Vitamin K antagonist (VKA) 2%, and dual-antiplatelet therapy (DAPT) 1.8% subgroup. Postoperative complications and readmission rates were compared between the two study groups and subgroups. Patients in the combined group 2 were older and they also carried more comorbidities compared to men in group 1 (p = 0.03, p = 0.001).The study groups had similar oncological results, with 40.4% of patients having locally advanced cancers. Catheter days were longer in the anticoagulation group (4.5 vs 4 days, p = 0.001). No significant differences were observed between study groups for overall, minor, and major complications (p = 0.160, 0.100, and 0.915, respectively). In addition, readmissions were low (5.6%) and similar between the study groups (p = 0.635). Under cautious management, RARP under diverse anticoagulation regimes is safe and has comparable results to men with no medications. Further prospective studies must be conducted to confirm our findings.

How Might the Number of Lymph Nodes Removed during RARP Impact the Postoperative Outcomes?

INTRODUCTION: Symptomatic lymphocele remains a relevant complication after pelvic tumor surgery. This study aims to investigate how the number of lymph nodes removed may influence postoperative outcomes and if it increases the probability of detecting lymph node metastasis. METHODS: The study included 500 patients who underwent RARP including lymphadenectomy performed by a single surgeon. Patients were divided into two groups: group 1 consisted of 308 patients with 20 or fewer lymph nodes removed (mean 15), while group 2 had 192 patients with over 20 nodes removed (mean 27). Perioperative data were analyzed, and postoperative outcomes were compared between groups. RESULTS: Overall, lymph node metastasis was detected in 17.8% of men. In detail, out of 19.6 lymph nodes removed, an average of 3.14 lymph nodes per patient showed metastasis, with a slightly higher incidence of 19.7% in group 2 compared to 16.5% in group 1, though not statistically significant (p = 0.175). The number of lymph node metastases was significantly higher in group 2 patients (3.47) versus group 1 (2.37) (p = 0.048). All complications except symptomatic lymphoceles (p = 0.004) were not significantly different between groups. Univariate linear regression analysis revealed no correlation between the number of removed lymph nodes and symptomatic lymphocele. However, it did correlate with catheter days and readmissions. CONCLUSION: A correlation may exist between the number of lymph nodes removed during RARP and an increased incidence of complications, particularly symptomatic lymphocele. A more extensive PLND may result in prolonged catheter days and increased readmissions. With the increased extent of pelvic lymphadenectomy, the probability of detecting lymphogenic metastasis rises. The diagnostic value of PLND is well established. Further randomized trials are needed to weigh its necessity and extent.

BMI Impact on Readmissions for Patients Undergoing Robot-Assisted Radical Prostatectomy: A Monocentric, Single-Surgeon Serial Analysis of 500 Cases.

Due to more difficult intraoperative courses, elevated rates of case abortion and unfavored postoperative outcomes in obese patients, urologists tend to consider other therapeutic modalities than prostate removal in very obese patients. With the surge in robotic surgery in the last two decades, more obese patients have undergone robot-assisted radical prostatectomy (RARP). OBJECTIVE: This current, monocentric, retrospective serial study investigates primarily the impact of obesity on readmissions and secondarily the major complications of RARP. METHODS: Five hundred patients from one referral center who underwent RARP between April 2019 and August 2022 were included in this retrospective study. To investigate the impact of patient BMI on postoperative outcomes, we divided our cohort into two groups with a cut-off of 30 kg/m2 (according to the WHO definition). Demographic and perioperative data were analyzed. Postoperative complications and readmission rates were compared between standard, normal patients (NOBMI-BMI under 30; n = 336, 67.2%) and overweight patients (OBMI-BMI equal to/more than 30; n = 164, 32.8%). RESULTS: OBMI patients had bigger prostates on TRUS, more comorbidities and worse baseline erectile function scores. They also received fewer nerve-sparing procedures than their counterparts (p = 0.005). Analysis showed no statistically significant differences in readmission rates or in minor or major complications (p = 0.336, 0.464 and 0.316, respectively). In a univariate analysis, BMI could predict positive surgical margins (p = 0.021). CONCLUSION: Performing RARP in obese patients seems to be safe and feasible, without major adverse events or elevated readmission rates. Obese patients should be informed preoperatively about the elevated risk of higher PSMs and technically more difficult nerve-sparing procedures.

How May Longer Console Times Influence Outcomes after Robot-Assisted Radical Prostatectomy (RARP)?

Longer operating time in radical prostatectomy may increase the risk of perioperative complications. Various factors such as cancer extent, the procedure's level of difficulty, habitus and previous surgeries may lengthen robot-assisted radical prostatectomy (RARP) and therefore compromise outcomes. OBJECTIVE: this study investigates the influence of operating time on outcomes after RARP in real life settings in a monocentric single surgeon study. METHODS: a total of 500 sequential patients who were operated on between April 2019 and August 2022 were involved. Men were allocated to three groups short (n = 157; 31.4%), under or equal to 120 min; average (n = 255; 51%), between 121 and 180 min; long (n = 88; 17.6%), above 180 min console time. Demographic, baseline and perioperative data were analyzed and compared between groups. Univariate logistic regression was completed to investigate the association between console time and outcomes and to predict factors which may prolong surgery. RESULTS: hospital stay and catheter days were significantly longer in group 3 with medians of 6 and 7 days (p < 0.001 and <0.001, respectively). Those findings were confirmed in univariate analysis, with p = 0.012 for catheter days and p < 0.001 for hospital stay. Moreover, major complications were higher in patients with longer procedures, at p = 0.008. Prostate volume was the only predictor of a prolonged console time (p = 0.005). CONCLUSION: RARP is a safe procedure and most patients will be discharged uneventfully. Yet, a longer console time is associated with a longer hospital stay, longer catheter days and major complications. Caution has to be taken in the large prostate to avoid longer procedures, which may prevent postoperative adverse events.

Effect of Neoadjuvant Hormonal Therapy on the Postoperative Course for Patients Undergoing Robot-Assisted Radical Prostatectomy.

OBJECTIVES: Neoadjuvant hormonal therapy (NHT) preceding robot-assisted radical prostatectomy (RARP) may be beneficial in high-risk cases to facilitate surgical resection. Yet, its improvement in local tumor control is not obvious. Its benefit regarding overall cancer survival is also not evident, and it may worsen sexual and hormonal functions. This study explores the effect of NHT on the perioperative course after RARP. METHODS: In this study, 500 patients from a tertiary referral center who underwent RARP by a specialized surgeon were retrospectively included. Patients were divided into two groups: the NHT (n = 55, 11%) group, which included patients who received NHT (median: 1 month prior to RARP), and the standard non-NHT (NNHT) group (n = 445, 89%). Demographic and perioperative data were analyzed. Postoperative results, complications, and readmission rates were compared between the groups. RESULTS: NHT patients were heterogeneous from the rest regarding cancer parameters such as PSA (25 vs. 7.8 ng/mL) and tumor risk stratification, and they were more comorbid (p = 0.006 for the ASA score). They also received fewer nerve-sparing procedures (14.5% vs. 80.4%), while the operation time was similar. Positive surgical margins (PSM) (21.8% vs. 5.4%) and positive lymph nodes (PLN) (56.4% vs. 12.7%) were significantly higher in the NHT group compared to the non-NHT (NNHT) group. Hospital stay was equal, whereas catheter days were 3 days longer in the NHT group. NHT patients also suffered more minor vesicourethral-anastomosis-related complications. Major complications (p = 0.825) and readmissions (p = 0.070) did not differ between groups. CONCLUSION: Patients receiving NHT before RARP did not experience more major complications or readmissions within 90 days after surgery. Patients with unfavorable, high-risk tumors may benefit from NHT since it facilitates surgical resection. Randomized controlled trials are necessary to measure the advantages and disadvantages of NHT.

Prostate Volume Influence on Postoperative Outcomes for Patients Undergoing RARP: A Monocentric Serial Analysis of 500 Cases.

Elevated prostate volume is considered to negatively influence postoperative outcomes after robot-assisted radical prostatectomy (RARP). We aim to investigate the influence of prostate volume on readmissions and complications after RARP. METHODS: A total of 500 consecutive patients who underwent RARP between April 2019 and August 2022 were included. Patients were dichotomized into two groups using a prostate volume cut-off of 50 mL (small and normal prostate (SNP) n = 314, 62.8%; large prostate n = 186, 37.2%). Demographic, baseline, and perioperative data were analyzed. The postoperative complications and readmission rates within 90 days after RARP were compared between groups. A univariate linear analysis was performed to investigate the association between prostate volume and other relevant outcomes. RESULTS: Patients with larger prostates had a higher IPSS score, and therefore, more relevant LUTS at the baseline. They had higher ASA scores (p = 0.015). They also had more catheter days (mean 6.6 days for SNP vs. 7.5 days for LP) (p = 0.041). All oncological outcomes were similar between the groups. Although statistical analysis showed no significant difference between the groups (p = 0.062), a trend for minor complications in patients with larger prostates, n = 37/186 (19.8%) for the LP group vs. n = 37/314 (11.7%) in the SNP group, was observed. Namely, acute urinary retention and secondary anastomosis insufficiency. Major complications with an SNP (4.4%) and LP (3.7%) (p = 0.708) and readmissions with an SNP (6.25%) and LP (4.2%) (p = 0.814) were infrequent and distributed equally between the groups. In univariate analysis, prostate volume could solely predict a longer console time (p = 0.005). CONCLUSIONS: A higher prostate volume appears to have minimal influence on the perioperative course after RARP. It can prolong catheter days and increase the incidence of minor complications such as acute urinary retention. However, it might predict minor changes in operating time. Yet, prostate volume has less influence on major complications, readmissions, or oncological results.

Comprehensive Geriatric Care in Older Hospitalized Patients with Depressive Symptoms.

BACKGROUND/OBJECTIVES: Depressive symptoms (DS) may interfere with comprehensive geriatric care (CGC), the specific multimodal treatment for older patients. In view of this, the aim of the current study was to investigate the extent to which DS occur in older hospitalized patients scheduled for CGC and to analyze the associated factors. Furthermore, we aimed to investigate whether DS are relevant with respect to outcomes after CGC. METHODS: For this retrospective study, all patients fulfilling the inclusion criteria were selected by reviewing case files. The main inclusion criterion was the completion of CGC within the defined period (May 2018 and May 2019) in the geriatrics department of the Diakonie Hospital Jung-Stilling Siegen (Germany). The Geriatric Depression Scale was used to asses DS in older adults scheduled for CGC (0-5, no evidence of DS; 6-15 points, DS). Scores for functional assessments (Timed Up and Go test (TuG), Barthel Index, and Tinetti Gait and Balance test) were compared prior to versus after CGC. Factors associated with the presence of DS were studied. RESULTS: Out of the 1263 patients available for inclusion in this study, 1092 were selected for the analysis (median age: 83.1 years (IQR 79.1-87.7 years); 64.1% were female). DS (GDS > 5) were found in 302 patients (27.7%). The proportion of female patients was higher in the subgroup of patients with DS (85.5% versus 76.3%, p = 0.024). Lower rates of patients diagnosed with chronic pulmonary obstructive disease were detected in the subgroup of patients without DS (8.0% versus 14.9%, p = 0.001). Higher rates of dizziness were observed in patients with DS than in those without (9.9% versus 6.2%, p = 0.037). After CGC, TuG scores improved from a median of 4 to 3 (p < 0.001) and Barthel Index scores improved from a median of 45 to 55 (p < 0.001) after CGC in both patients with and without DS. In patients with DS, the Tinetti score improved from a median of 10 (IQR: 4.75-14.25) prior to CGC to 14 (IQR 8-19) after CGC (p < 0.001). In patients without DS, the Tinetti score improved from a median of 12 (IQR: 6-7) prior to CGC to 15 (IQR 2-20) after CGC (p < 0.001). CONCLUSIONS: DS were detected in 27.7% of the patients selected for CGC. Although patients with DS had a poorer baseline status, we detected no difference in the degree of improvement in both groups, indicating that the performance of CGC is unaffected by the presence of DS prior to the procedure.

Omitting routine cystography after RARP: Analysis of complications and readmission rates in suprapubic and transurethral drained patients.

OBJECTIVES: Robot-assisted radical prostatectomy (RARP) has become the therapy of choice for local treatment of prostate cancer. Postoperatively, urologists perform cystography before removing urinary catheters due to concerns about the integrity of the vesicourethral anastomosis. This study aims to evaluate the safety of waiving cystography before early catheter removal after RARP. METHODS: A total of 514 patients from two tertiary referral centers who underwent RARP were retrospectively included. Patients received postoperative urinary drainage by transurethral (TUC) or suprapubic catheter (SPC). During the first year, both centers performed routine cystography before removing TUC or SPC on postoperative day 5. In the following year, management changed and catheters were removed without cystography unless indicated by the surgeon. Demographic and perioperative data were analyzed. Postoperative complications and readmission rates were compared between standard cystography (StCG), no cystography (NCG), and selective cystography (SCG). RESULTS: Groups were comparable regarding demographic and oncological parameters. Analysis showed no significant difference regarding major complications and readmission rates between standard and no cystography (p = 0.155 and 0.998 respectively). Omitting routine cystography did not lead to inferior postoperative courses regardless of both urinary drainage used and tumor stage. Subgroup analysis showed an increase of major complications in SCG patients when compared with NCG (p = 0.003) while readmissions remained comparable (p = 0.554). CONCLUSION: Waiving routine cystography before early catheter removal after RARP appears to be safe and feasible regardless of urinary drainage. However, the selective cystogram at the surgeon's request still plays a role in monitoring patients with an elevated risk profile.

Lessons learned after one year of COVID-19 from a urologist and radiotherapist view: A German survey on prostate cancer diagnosis and treatment.

INTRODUCTION: Since the beginning of the pandemic in 2020, COVID-19 has changed the medical landscape. International recommendations for localized prostate cancer (PCa) include deferred treatment and adjusted therapeutic routines. MATERIALS AND METHODS: To longitudinally evaluate changes in PCa treatment strategies in urological and radiotherapy departments in Germany, a link to a survey was sent to 134 institutions covering two representative baseline weeks prior to the pandemic and 13 weeks from March 2020 to February 2021. The questionnaire captured the numbers of radical prostatectomies, prostate biopsies and case numbers for conventional and hypofractionation radiotherapy. The results were evaluated using descriptive analyses. RESULTS: A total of 35% of the questionnaires were completed. PCa therapy increased by 6% in 2020 compared to 2019. At baseline, a total of 69 radiotherapy series and 164 radical prostatectomies (RPs) were documented. The decrease to 60% during the first wave of COVID-19 particularly affected low-risk PCa. The recovery throughout the summer months was followed by a renewed reduction to 58% at the end of 2020. After a gradual decline to 61% until July 2020, the number of prostate biopsies remained stable (89% to 98%) during the second wave. The use of RP fluctuated after an initial decrease without apparent prioritization of risk groups. Conventional fractionation was used in 66% of patients, followed by moderate hypofractionation (30%) and ultrahypofractionation (4%). One limitation was a potential selection bias of the selected weeks and the low response rate. CONCLUSION: While the diagnosis and therapy of PCa were affected in both waves of the pandemic, the interim increase between the peaks led to a higher total number of patients in 2020 than in 2019. Recommendations regarding prioritization and fractionation routines were implemented heterogeneously, leaving unexplored potential for future pandemic challenges.

To defer or not to defer? A German longitudinal multicentric assessment of clinical practice in urology during the COVID-19 pandemic.

INTRODUCTION: After the outbreak of COVID-19 unprecedented changes in the healthcare systems worldwide were necessary resulting in a reduction of urological capacities with postponements of consultations and surgeries. MATERIAL AND METHODS: An email was sent to 66 urological hospitals with focus on robotic surgery (RS) including a link to a questionnaire (e.g. bed/staff capacity, surgical caseload, protection measures during RS) that covered three time points: a representative baseline week prior to COVID-19, the week of March 16th-22nd and April 20th-26th 2020. The results were evaluated using descriptive analyses. RESULTS: 27 out of 66 questionnaires were analyzed (response rate: 41%). We found a decrease of 11% in hospital beds and 25% in OR capacity with equal reductions for endourological, open and robotic procedures. Primary surgical treatment of urolithiasis and benign prostate syndrome (BPS) but also of testicular and penile cancer dropped by at least 50% while the decrease of surgeries for prostate, renal and urothelial cancer (TUR-B and cystectomies) ranged from 15 to 37%. The use of personal protection equipment (PPE), screening of staff and patients and protection during RS was unevenly distributed in the different centers-however, the number of COVID-19 patients and urologists did not reach double digits. CONCLUSION: The German urological landscape has changed since the outbreak of COVID-19 with a significant shift of high priority surgeries but also continuation of elective surgical treatments. While screening and staff protection is employed heterogeneously, the number of infected German urologists stays low.
