Evaluating the Differences of Wound Related Complications in Robotically Assisted Radical Cystectomy vs Open Radical Cystectomy

OBJECTIVE

To determine whether robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) compared to open radical cystectomy (ORC) or RARC with extracorporeal urinary diversion (ECUD) would result in a decreased rate of surgical site complications. RARC has been shown to be non-inferior to ORC. Both RARC and ORC are complicated by a high rate of perioperative morbidity, including wound-related complications, which may be decreased by a robotic approach with intracorporeal diversion.

METHODS

A retrospective review of our bladder cancer database for patients undergoing radical cystectomy from 2013-2021. Patients were stratified by surgical technique as RARC with ICUD vs ORC vs RARC with ECUD. Surgical site complications were measured at both 30- and 90-day intervals.

RESULTS

Of the 269 patients, 127 (47.2%) had RARC with ICUD, 118 (43.7%) had ORC, and 24 (8.9%) had RARC with ECUD (mean ages 71.0, 69.5, and 67.5, respectively). A comparison of the 3 groups demonstrated statistical significance at both the 30-day (P <.001) and 90-day (P <.001) timeframes for total surgical site complications, with RARC with ICUD having the fewest amount of patients experiencing a surgical site complication (0.8%) followed by ORC (25.4%) and RARC with ECUD (29.2%).

CONCLUSION

Overall, we observed lower surgical site complication rates among patients undergoing RARC with ICUD compared to patients who underwent ORC or RARC with ECUD. This study suggests that decreased surgical site complications may be one benefit of the minimally invasive approach, particularly in patients at high risk for surgical site complications after radical cystectomy.

Perioperative factors and 30-day major complications following radical cystectomy: A single-center study in Thailand

Objective

This study aims to evaluate the prevalence of early postoperative complications of radical cystectomy, using standardized reporting methodology to assess perioperative characteristics and determine risk factors for major complications.

Materials and methods

A retrospective study included 254 consecutive bladder cancer patients undergoing RC between 2012 and 2020 at a urological cancer referral center. Postoperative complications within 30 days were recorded and graded according to the Clavien-Dindo classification (CDC). The study examined risk factors, including novel inflammatory-nutrition biomarkers and perioperative serum chloride.

Results

Total complications were observed in 135 (53 %). Of these, 47 (18.5 %) were high grade (CDC ≥ 3). Wound dehiscence was the most common complication, occurring in 14 (5.5 %) patients. Independent risk factors for major complications included an age-adjusted Charlson comorbidity index (ACCI) > 4 and thrombocytopenia (odds ratio [OR] 3.67 and OR 8.69). Preoperative platelet counts < 220,000/μL and albumin < 3 mg/dL were independent risk factors for wound dehiscence (OR 3.91 and OR 4.72). Additionally, postoperative hypochloremia was a risk factor for major complications (OR 13.71), while novel serum biomarkers such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammatory response index (SIRI), and prognostic nutritional index (PNI) were not associated with early major complications.

Conclusion

Patients who have multiple comorbidities are at a greater risk of developing major complications after undergoing RC. Our result suggests that preoperative platelet counts and serum albumin levels are associated with wound dehiscence.

A Proposal for Standardization of Early Outcomes Following Robot-Assisted Radical Cystectomy (RARC): RARC Tetrafecta

BACKGROUND

Currently, there is no dedicated tool to record the early outcomes of robot-assisted radical cystectomy (RARC), and existing criteria for longer-term outcomes require a minimum of 3 months for assessment. However, early evaluation is essential to prevent future morbidity and mortality, especially in surgeries with a high risk of complications in the short term. We propose a comprehensive approach to report early RARC outcomes and investigate the influence of surgeon experience on these results.

PATIENTS AND METHODS

We retrospectively analyzed the outcomes of patients who underwent RARC for bladder cancer between April 2009 and April 2020. The cohort was divided chronologically into three groups: patients 1-60 in group 1, 61-120 in group 2, and 121-192 in group 3. Patients with yields of ≥ 16 lymph nodes (LN), negative soft tissue surgical margins, absence of transfusion, and absence of major complications at 30 days were regarded as attaining the RARC tetrafecta.

RESULTS

Of the 192 included patients, 93 (48.4%) achieved RARC tetrafecta, with the proportion increasing with surgical experience from 41.7% in group 1 to 55.6% in group 3. Age [odds ratio (OR) 0.947; 95% confidence interval (CI) 0.924-0.970; P = 0.021], LN yield (OR 1.432; 95% CI 1.139-1.867; P = 0.001), and greater surgical experience with RARC (> 120 patients; OR 2.740; 95% CI 1.231-6.100; P = 0.014) were significantly associated with the achievement of RARC tetrafecta.

CONCLUSIONS

RARC tetrafecta could be a comprehensive method for reporting early outcomes in patients undergoing RARC, with improvements aligned with the surgeon's experience.

Extraperitoneal Versus Intraperitoneal Radical Cystectomy for Bladder Cancer: A Systematic Review and Meta-Analysis

BACKGROUND

This study aimed to compare perioperative and oncologic outcomes of extraperitoneal radical cystectomy (EPRC) and transperitoneal radical cystectomy (TPRC).

METHODS

A systematical search of multiple scientific databases was performed in September 2022. The systematic review and cumulative meta-analysis of the primary outcomes of interest were performed according to the PRISMA and AMSTAR guidelines and registered in the PROSPERO database (PROSPERO [CRD42022359322]).

RESULTS

The review and analysis included eight studies with 989 participants. No significant differences were found between EPRC and TPRC in terms of operation time, estimated blood loss (EBL), hospital length of stay (LOS), or transfusion. A shorter exhaust time (standardized mean difference [SMD] - 0.59; 95 % confidence interval [CI] - 0.97 to 0.21; p = 0.002) and time to liquid intake (SMD, - 0.56; 95 % CI - 1.07 to 0.04; p = 0.03) were associated with EPRC. No clinically meaningful difference was observed in terms of postoperative infection, wound complications, postoperative genitourinary complications, late postoperative complications, early major complications, or late major complications. However, EPRC was related to lower incidences of early postoperative complications (odds ratio [OR], 0.66; 95 % CI 0.51-0.86; p = 0.002), gastrointestinal complications (OR 0.28; 95 % CI 0 0.17-0.46; p < 0.00001), and postoperative ileus (OR 0.38; 95 % CI 0.25-0.59; p < 0.0001). A higher incidence of postoperative lymphocele was associated with EPRC (OR 3.05; 95 % CI 1.13-8.25; p = 0.03). No clinically meaningful difference was found in terms of positive surgical margin (PSM), local recurrence, distant metastasis, or OS.

CONCLUSIONS

Although EPRC had a higher incidence of lymphoceles than TPRC, it was found to have similar oncologic outcomes and fewer early complications, particularly in terms of postoperative gastrointestinal complications and ileus. These results suggest that EPRC is a safe option both functionally and oncologically.

Evaluation of short-term outcomes of neoadjuvant chemotherapy followed by radical cystectomy in muscle-invasive bladder cancer: a single Egyptian institution experience

BACKGROUND AND AIM

Neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) became the standard of care for muscle-invasive bladder cancer (MIBC) in the last few years. We aimed to evaluate the radiological, pathological responses to NAC, and the 30-day surgical outcomes after RC in MIBC.

PATIENTS AND METHODS

A retrospective cohort study involving adult patients with localized urothelial MIBC who received NAC followed by RC at the National Cancer Institute of Egypt (NCI-E) for 2 years (2017 and 2018). Out of 235 MIBC cases, we recognized 72 patients (30%) who fitted the eligibility criteria.

RESULTS

A cohort of 72 patients with a median age of 60.5 years (range 34-87). Hydronephrosis, gross extravesical extension (cT3b), and radiologically negative nodes (cN0) were depicted initially in 45.8, 52.8, and 83.3% of patients, respectively. Gemcitabine and cisplatin (GC) was the rampant NAC employed in 95.8%. Radiological evaluation post NAC using RECIST v1.1 revealed a response rate (RR) of 65.3% in bladder tumor and progressive disease in the former and lymph nodes encountered in 19.4 and 13.9%, respectively. The median time from the end of NAC to surgery was 8.1 weeks (range 4-15). Open RC and ileal conduit were the most common types of surgery and urinary diversion, respectively. Pathological down-staging was encountered in 31.9%, and only 11 cases (15.3%) achieved pathological complete response (pCR). The latter was significantly correlated with the absence of hydronephrosis, low-risk tumors, and associated bilharziasis (p = 0.001, 0.029, and 0.039, respectively). By logistic regression, the high-risk category was the only independent factor associated with a poor likelihood of achieving pCR (OR 4.3; 95% CI 1.1-16.7; p = 0.038). Thirty-day mortality occurred in 5(7%) patients, and 16(22%) experienced morbidity, with intestinal leakage being the most frequent complication. cT4 was the only significant factor associated with post-RC morbidity and mortality compared to cT2 and cT3b (p = 0.01).

CONCLUSIONS

Our results are further supporting the radiological and pathological benefits of NAC in MIBC, evidenced by tumor downstaging and pCR. The complication rate after RC is still considerable; hence, more larger studies are necessary to postulate a comprehensive risk assessment tool for patients who would get the maximum benefit from NAC, hoping to accomplish higher complete response rates with ultimately increased adoption of the bladder preservation strategies.

Bladder preservation in complicated invasive urothelial carcinoma following treatment with cisplatin/gemcitabine plus tislelizumab: A case report

BACKGROUND

Invasive urothelial carcinoma (UC) with squamous and glandular differentiation is a highly malignant and complicated pathological subtype, and the standard care is radical cystectomy (RC). However, urinary diversion after RC significantly reduces patient quality of life, thus bladder-sparing therapy has become a research hotspot in this field. Recently, five immune checkpoint inhibitors have been approved for systemic therapy of locally advanced or metastatic bladder cancer by the Food and Drug Administration, but the efficacy of immunotherapy combined with chemotherapy for invasive UC is still unknown, especially for pathological subtypes with squamous and glandular differentiation.

CASE SUMMARY

We report the case of a 60-year-old male who complained of repetitive painless gross hematuria and was diagnosed with muscle-invasive bladder cancer with squamous and glandular differentiation, defined as cT3N1M0 according to the American Joint Committee on Cancer, who had a strong desire to preserve the bladder. Immunohistochemical staining revealed that programmed cell death-ligand 1 (PD-L1) expression in the tumor was positive. Thus, a transurethral resection to maximize removal of the bladder tumor was performed under cystoscopy, and the patient subsequently received a combination of chemotherapy (cisplatin/gemcitabine) and immunotherapy (tislelizumab) treatment. No tumor recurrence in the bladder was observed following pathological and imaging examination after 2 cycles and 4 cycles of treatment, respectively. The patient achieved bladder preservation and has been tumor-free for more than two years.

CONCLUSION

This case shows that the combination of chemotherapy and immunotherapy might be an effective and safe treatment strategy for PD-L1 expression positive UC with divergent histologic differentiation.

Comparison of Laparoscopic and Open Radical Cystectomy for Muscle-Invasive Bladder Cancer

The goal of the study was to compare laparoscopic and open radical cystectomy in treatment of muscle-invasive bladder cancer in the Department of Urology and Oncological Urology PUM in Szczecin. A total of 78 patients in the study group underwent laparoscopic cystectomy between 2016−2018, and 81 patients from the control group had open cystectomy between 2014−2016. Both groups were comparable in terms of age, stage, and concomitant diseases. The 3 year overall survival was comparable in both groups (37.7% for laparoscopy and 44.4% for open, p = 0.64). There was no difference in positive surgical margin rate. Lymph node yield during cystectomy was higher in open cystectomy (14 vs. 11.5, p = 0.001). Post-operative blood loss and transfusion rates were lower in laparoscopic cystectomy. Decrease in hemoglobin level was lower in laparoscopy (0.9 mmol/L, p < 0.001). Intraoperative transfusion rate was 11.8% in laparoscopy vs. 34.8% in open cystectomy (p = 0.002). Operation time, duration of hospitalisation, and time to full oral alimentation were comparable in both groups. Patients with BMI > 30 kg/m2 and those with pT3-T4 cancer in the laparoscopy group had less septic complications post-operatively. Patients with ASA score ≥ 3 from the laparoscopy group had fewer reoperations due to ileus. Laparoscopic cystectomy is less invasive and offers similar oncological outcomes to the open method. Patients benefit from less tissue trauma, less blood loss, and faster recovery. The presented results, as well as other publications, should encourage a wider use of this procedure in everyday urological practice.

Comparative study on the clinical effect of preparing neobladder with different lengths of ileum

OBJECTIVE

To investigate the relationship between orthotopic U-shaped ileal neobladder volume and bladder function. To investigate the correlation between the volume of the radical cystectomy and the U-shaped ileal neobladder in situ and the function of the bladder.

METHODS

The clinical data of patients undergoing in orthotopic U-shaped neobladder in our hospital were retrospectively analyzed. They were divided into two groups according to the length of the retained ileum. Group 1: The length of the ileum was 25-35cm (including 35cm), and the second group: the length of the ileum was 35-45cm. The basic information, cushion usage, urodynamic examination and complications of the two groups were obtained.

RESULTS

A total of 88 patients were included in the study, including 33 in the first group and 55 in the second group. There was no statistical difference in general data, lymph node collection, lymph node positive rate, positive margin rate, postoperative pathological stage, pathological grade, pathological type, intraoperative blood loss, blood transfusion, postoperative hospital stay, and complications between the two groups of patients. significance. Although the usage of urine pads in group 1 was more than that in group 2 in the short term after operation (P<0.05), it started from the third year after operation. Patients in group 1 used less cushion than group 2 (P<0.05). Urodynamic examination was performed on the patients, and the bladder function of group 1 maintained satisfactory time longer than that of group 2. The total number of deaths in the two groups was 12 and 23, respectively. The 5-year overall survival (OS) rate of group 1 was 53.60%, and the 5-year overall survival rate of group 2 was 52.9%.

CONCLUSIONS

A new bladder formed by cutting the ileum with a length of 25-35 cm (including 35cm) has a longer time to maintain good bladder function than cutting the ileum with a length of 35-45 cm to produce a new bladder.

Fascial dehiscence after radical cystectomy: Is abdominal exploration mandatory?

BACKGROUND

Fascial dehiscence after radical cystectomy may have serious clinical implications. To optimize its management, we sought to describe accompanying intraabdominal findings of post-cystectomy dehiscence repair and determine whether a thorough intraabdominal exploration during its operation is mandatory.

METHODS

We retrospectively reviewed a multi-institutional cohort of patients who underwent open radical cystectomy between 2005 and 2020. Patients who underwent exploratory surgery due to fascial dehiscence within 30 days post-cystectomy were included in the analysis. Data collected included demographic characteristics, the clinical presentation of dehiscence, associated laboratory findings, imaging results, surgical parameters, operative findings, and clinical implications. Potential predictors of accompanying intraabdominal complications were investigated.

RESULTS

Of 1301 consecutive patients that underwent cystectomy, 27 (2%) had dehiscence repair during a median of 7 days post-surgery. Seven patients (26%) had accompanying intraabdominal pathologies, including urine leaks, a fecal leak, and an internal hernia in 5 (19%), 1 (4%), and 1 (4%) patients, respectively. Accompanying intraabdominal findings were associated with longer hospital stay [20 (IQR 17, 23) vs. 41 (IQR 29, 47) days, P = 0.03] and later dehiscence identification (postoperative day 7 [IQR 5, 9] vs. 10 [IQR 6, 15], P = 0.03). However, the rate of post-exploration complications was similar in both groups. A history of ischemic heart disease was the only predictor for accompanying intraabdominal pathologies (67% vs. 24%; P = 0.02).

CONCLUSIONS

A substantial proportion of patients undergoing post-cystectomy fascial dehiscence repair may have unrecognized accompanying surgical complications without prior clinical suspicion. While cardiovascular disease is a risk factor for accompanying findings, meticulous abdominal inspection is imperative in all patients during dehiscence repair. Identification and repair during the surgical intervention may prevent further adverse, possibly life-threatening consequences with minimal risk for iatrogenic injury.

The effect of retroperitonealization of ureteroileal anastomosis on perioperative complications of radical cystectomy with ileal conduit urinary diversion

BACKGROUND

Radical cystectomy (RC) has been considered the standard management of muscle-invasive bladder cancer. Despite the improvements in surgical techniques and perioperative care, RC is still associated with high perioperative morbidity and mortality.

OBJECTIVE

This study aims to evaluate the effect of retroperitonealization of ureteroileal anastomosis on perioperative complications of RC with ileal conduit urinary diversion.

PATIENTS AND METHODS

This is a retrospective cohort study. We reviewed medical charts of 876 patients who underwent RC between 2016 and 2021. Based on the inclusion and exclusion criteria, 748 patients entered the study. According to retroperitonealization of the ureteroileal anastomosis, patients were categorized into two groups (group I without retroperitonealization of the ureteroileal anastomosis and group II with retroperitonealization of the ureteroileal anastomosis). Patients' characteristics and occurrences of any complications and high-grade complications were compared between these groups.

RESULTS

In comparing the complication categories between the two groups, fewer patients in group II suffered from gastrointestinal, urinary, and cardiac events (p values were 0.018, 0.021, and 0.013, respectively). Moreover, fewer patients in group II experienced any complications and high-grade complications (p values were < 0.001 and < 0.001, respectively). The length of hospital stay was also significantly shorter in group II (p < 0.001).

CONCLUSIONS

RC is associated with comparatively high perioperative morbidity and mortality. In the present study, 61% of the patients experienced at least one complication postoperatively. Retroperitonealization of the ureterointestinal anastomosis may decrease perioperative adverse events of RC with ileal conduit urinary diversion.

Treatment trends for muscle-invasive bladder cancer in Germany from 2006 to 2019

Purpose

To examine national treatment trends of muscle-invasive bladder cancer (MIBC) in Germany with a special focus on radical cystectomy (RC).

Patients and methods

Population-based data were derived from the nationwide hospital billing database of the German Federal Statistical Office and institution-related information from the reimbursement.INFO tool based on hospitals’ quality reports from 2006 to 2019. Additionally, we used the German National Center for Cancer Registry data to analyze all cases of bladder cancer with stage ≥ T2 who received RC, chemotherapy, radiation therapy or a combination from 2006 to 2017.

Results

The annual number of RC cases in Germany increased by 28% from 5627 cases in 2006 to 7292 cases in 2019 (p = 0.001). The proportion of patients undergoing RC remained constant at about 75% in all age groups between 2006 and 2017 (p = 0.3). Relative to all performed RC, the proportion of patients > 75 years increased from 25% in 2006 to 38% in 2019 (p = 0.03). The proportion of patients receiving a combination of RC and chemotherapy increased from 9% in 2006 to 13% in 2017 (p = 0.005). In 2006, 8 of 299 urology departments (2.7%) performed more than 50 RCs per year, which increased to 17 of 360 (4.7%) in 2019. In 2019, 107 departments (29%) performed 25–49 RCs and 236 (66%) departments performed < 25 RCs.

Conclusion

In Germany, three out of four patients with MIBC receive RC and the proportion of patients > 75 years is increasing. The combination of surgery and chemotherapy is increasingly used. With overall increasing case numbers, there is a slight tendency towards centralization.

External validation of Pentafecta in patients undergoing laparoscopic radical cystectomy: results from a high-volume center

BACKGROUND

To investigate whether Pentafecta is suitable for bladder cancer patients receiving laparoscopic radical cystectomy (LRC).

METHODS

From November 2013 to December 2020, muscle invasive Bladder Cancer (MIBC) and non-muscle invasive Bladder Cancer (NMIBC) patients who received LRC and urinary diversion were retrospectively analyzed. Pentafecta was defined as meeting five criteria: negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year. Analyze the achievement of five criteria and compare the overall survival (OS) of Pentafecta group with non-attainment group. Multivariable Cox's regression was performed to evaluate the impact of Pentafecta on OS. Multivariable logistic regression was performed to explore the effect of surgical experience on Pentafecta attainment.

RESULTS

A total of 340 patients were included, negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year were observed in 95.3%, 30.3%, 83.8%, 75.0% and 85.6% of patients, respectively. Pentafecta group had a significantly longer OS than the non-attainment group (P = 0.027). The group with 10-15 LNs removed and meeting the other four criteria had a similar OS to group with ≥ 16 LNs removed (Pentafecta group) (5-year OS: 67.3% vs 72.7%, P = 0.861). Pentafecta (HR = 0.33, P = 0.011), positive lymph nodes (HR = 2.08, P = 0.028) and MIBC (HR = 3.70, P < 0.001) were all significant predictors of OS in multivariable Cox's regression. Surgical experience (OR = 1.05, P < 0.001), conduit (OR = 2.09, P = 0.047) and neobladder (OR = 2.47, P = 0.048) were all independent predictors of Pentafecta attainment in multivariable logistic regression.

CONCLUSIONS

Pentafecta is suitable for bladder cancer patients receiving LRC and has the potential to be a valuable tool for evaluating the quality of LRC. Based on Pentafecta analysis, removing 10 LNs instead of 16 LNs as the one of the five criteria may be more appropriate for bladder cancer patients.

Risk of recurrence and long-term mortality following radical cystectomy for bladder cancer

PURPOSE

To investigate the risk of recurrence and long-term mortality after radical cystectomy (RC) for bladder cancer (BC) at a high-volume tertiary referral center in Denmark over 19 years.

MATERIALS AND METHODS

Patients undergoing RC between the 1st of January 2000 to 31st of December 2018 were included. Patient data were manually retrieved from electronic patient files. Follow-up ended 18th of May 2020. Cumulative incidences were used to assess risk of recurrence and mortality using competing risk modelling. Cause-specific Cox regression models were used for multivariable analysis.

RESULTS

A total of 1267 patients underwent RC of which 1042 were eligible for analysis. Overall mortality was 40% and 56% after 5 and 10 years, respectively. The cumulative incidence of recurrence and BC specific mortality was high within the first 2 years. Only 3.2% of the patients with recurrence were alive at the end of follow-up. The cumulative incidence of BC mortality after 5 years was 6.7% (95% CI 3.6-9.9) and 10% (95% CI 6.8-14) for patients with ≤ pT1bN0 and pT2N0, respectively. For patients with lymph node positive disease the cumulative incidence of BC mortality after 5 years was 65% (95% CI 58-71).

CONCLUSIONS

We found a significant risk of recurrence and disease-specific mortality following RC for BC, especially within the first 2 years following surgery. Our data seem comparable to other large cohorts. The chance of long-term survival following recurrence is low and there is a continuous need to improve adjuvant or salvage strategies following RC.

Mini-laparotomy radical cystectomy with limited bowel externalization during ileal conduit urinary diversion reduces the rate of postoperative complications: a match-paired, single centered analysis

OBJECTIVE

To assess the feasibility and functional outcomes of mini-laparotomy radical cystectomy (RC) in association with limited bowel externalization during ileal conduit urinary diversion.

METHODS

Between January 2018 and March 2020, 53 patients underwent RC plus pelvic lymph node dissection (PLND) for invasive carcinoma of the urinary bladder. This group of patients was intentionally treated utilizing the mini-laparotomy approach, with the addition of limited bowel externalization during conduit preparation and match-paired with 46 examinees from a historical series of patients who underwent conventional open RC plus PLND and ileal conduit diversion. Clinicopathological features and perioperative outcomes were examined from medical records, while postoperative pain was evaluated through the Visual Analog Scale for Pain (VAS). Mean pain scores were evaluated on postoperative days (POD) 1-3.

RESULTS

There was no difference in specific intraoperative complications between groups, with a median (range) incision length of 8 (5-10) cm within the first group and 16.3 (12-22.6) cm within the second group. The first group had less postoperative pain compared with patients in the second group, with mean pain scores significantly lower across POD 1-3, 3.8 (IQR: 0-6) versus 6.7 (IQR: 3.8-8.1) and 2.5 (IQR: 1-3.7) versus 4.6 (IQR: 3-6), respectively (p = .012 and .002).

CONCLUSIONS

By using this technique, we were able to significantly reduce patients' postoperative pain, time to bowel restitution, and hospital stay, which are major issues in minimizing short-term postoperative complications of conventional open surgery.

Successful management of a high-output urinary fistula following radical cystectomy and ileal conduit: a conservative approach

Urinary leak following ileal conduit after a radical cystectomy is a rare yet serious complication which presents early in the postoperative period. We herein present a case of a 38-year-old man diagnosed with recurrent high-grade non-muscle invasive bladder carcinoma. He underwent robot-assisted radical cystectomy and bilateral pelvic lymph node dissection. Postoperatively, the patient developed a high output urinary fistula (800-1000 mL/day) which was confirmed by fluid creatinine levels and a contrast study. He was managed successfully with a conservative approach. The leak subsided in 6 weeks and on follow-up patient is doing well. Most of the literature favours a surgical approach in such cases, however with optimal nutritional support (enteral/parenteral), adequate diversion of urine, percutaneous drainage of undrained collections, adequate intravenous antibiotics and good nursing care, resurgery with its associated morbidity can be avoided resulting in successful outcomes.

Age and risk of major complications in patients undergoing radical cystectomy for muscle invasive bladder cancer

Introduction

Radical cystectomy is the treatment of choice for patients with muscle invasive bladder cancer (MIBC), but it may be unsafe in older patients.

Aim

In this study, we investigated whether age and selected clinical characteristics were associated with outcomes of radical cystectomy.

Material and methods

We enrolled 434 patients with MIBC who underwent radical cystectomy between 2012 and 2016, and we classified them into three age groups: < 65, 66–74, and ≥ 75 years. Postoperative complications were classified on the Clavien-Dindo scale. Regression models were used to find predictors of major postoperative complications (Clavien-Dindo score of 3 or more), long hospital stay (> 7 days), blood loss, and operating time. The models included American Society of Anesthesiologists scores, age group, sex, body mass index, Tumor Nodes Metastasis scores, type of urine derivation (ileal conduit or orthotopic bladder vs. ureterocutaneostomy), and operation type (open vs. laparoscopic).

Results

In the regression models, age was not a significant predictor of major complications, long hospital stay, or blood loss (p ≥ 0.206). Older age was associated with shorter surgery times (p = 0.002). Higher preoperative American Society of Anesthesiologists scores tended to be associated with a greater risk of major complications (odds ratio, 1.47; p = 0.092).

Conclusions

Older age was not associated with an increased risk of major complications in patients who undergo radical cystectomy because of MIBC. Therefore, older age alone should not be a contraindication to this operation.

Risk factors for wound dehiscence following radical cystectomy: a prediction model

Objectives:

Radical cystectomy (RC) is a complex urologic procedure performed for the treatment of bladder cancer and causes significant morbidity. Wound dehiscence (WD) is a major complication associated with RC and is associated with multiple risk factors. The objectives of this study are to identify clinical risk factors for incidence of WD and develop a risk-prediction model to aid in patient risk-stratification and improvement of perioperative care.

Materials and Methods:

The American College of Surgeons – National Surgical Quality Improvement Program (ACS-NSQIP) database was used to derive the study cohort. A univariate analysis provided nine variables eligible for multivariate model entry. A stepwise logistic regression analysis was conducted and refined considering clinical relevance of the variables, and then bootstrapped with 1000 samples, resulting in a five-factor model. Model performance and calibration were assessed by a receiver operated curve (ROC) analysis and the Hosmer–Lemeshow test for goodness of fit, respectively.

Results:

A cohort of 11,703 patients was identified from years 2005 to 2017, with 342 (2.8%) incidences of WD within 30 days of operation. The final five-factor model included male gender [odds ratio (OR) = 2.5, p < 0.001], surgical site infection (OR = 6.3, p < 0.001), smoking (OR = 1.8, p < 0.001), chronic obstructive pulmonary disease (COPD) (OR = 1.9, p < 0.001), and weight class; morbidly obese patients had triple the odds of WD (OR = 2.9, p < 0.001). The ROC analysis provided a C-statistic of 0.76 and calibration R² was 0.99.

Conclusion:

The study yields a statistically robust and clinically beneficial five-factor model for estimation of WD incidence risk following RC, with good performance and excellent calibration. These factors may assist in identifying high-risk patients, providing preoperative counseling and thus leading to improvement in perioperative care.

Treating Elderly Patients With Muscle-Invasive Bladder Cancer

Bladder cancer is an extremely common cancer that primarily affects individuals aged >65 years. In caring for patients with bladder cancer, clinicians must also consider care of older persons in general. Management of muscle-invasive bladder cancer (MIBC) involves multidisciplinary treatment planning, because curative-intent therapy includes either surgery or radiation, with consideration of the role of systemic therapy. As clinicians develop a treatment plan, considering a geriatric oncology perspective may enhance patient care and influence outcomes for this large and growing population. Similarly, treatment plan development must also consider aspects unique to an older patient population, such as altered organ function, increased comorbidity, decreased functional reserve, and perhaps altered goals of treatment. Thus a thorough evaluation inclusive of disease assessment and geriatric assessment is essential to care planning. Population-based data show that as patients with MIBC age, use of standard therapies declines. Given the complexities of coordinating a multidisciplinary care plan, as well the complexities of treating a heterogeneous and potentially vulnerable older patient population, clinicians may benefit from upfront assessments to inform and guide the process. This review highlights the unique treatment planning considerations for elderly patients diagnosed with MIBC.

Impact of perioperative blood transfusions on oncologic outcomes after radical cystectomy: A systematic review and meta-analysis of comparative studies

This study aimed at systematically analyzing and evaluating the impact of perioperative blood transfusions (PBT) on oncologic outcomes of patients undergoing radical cystectomy for bladder cancer. This systematic review follows the recommendations of the Cochrane Handbook for Systematic Reviews and Interventions and was conducted in line with the PRISMA statement and the AMSTAR II criteria. A comprehensive database search was performed based on the PICO criteria. Two independent reviewers performed all screening steps and quality assessment. Risk of bias and certainty in evidence were assessed with the Newcastle Ottawa Scale for non-randomized trials and the GRADE approach. Of 1123 identified studies 20 were eligible for qualitative analysis and 15 for quantitative analysis reporting on 21,915 patients. Receiving a PBT was associated with an increased risk of all-cause mortality (hazard ratio (HR) [95% confidence interval (CI)]: 1.29 [1.18, 1.40]; p < 0.001), cancer-specific mortality (HR [CI]: 1.27 [1.15; 1.41]; p < 0.001) and disease recurrence (HR [CI]: 1.22 [1.12; 1.34]; p < 0.001). Subgroup analysis of transfusion timing revealed a significantly increased risk of mortality with intraoperative or combined intra- and postoperative transfusions compared to postoperative transfusion only for all three outcomes (p < 0.001). Leukocyte-depletion was associated with increased all-cause mortality, but not cancer-specific mortality. The administration of PBT negatively impacts oncological outcomes after radical cystectomy. Therefore, careful treatment indication and strict adherence to transfusion guidelines is encouraged in order to avoid adverse effects during the perioperative course.

Short-term morbidity and mortality following radical cystectomy: a systematic review

OBJECTIVE

To study short-term (<90 days) morbidity and mortality following radical cystectomy (RC) for bladder cancer and identify modifiable risk factors associated with these.

DESIGN

Systematic review.

METHODS

The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and EMBASE were searched for relevant papers on 11 June 2019 and rerun on 27 May 2020. Studies reporting complications, reoperations, length of stay and mortality within 90 days were included. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine and the quality of evidence was assessed using the Newcastle-Ottawa Scale.

RESULTS

The search retrieved 1957 articles. Sixty-six articles were included. The quality of evidence was poor to good. Most studies were retrospective, and no randomised clinical trials were identified. Of included studies a median of 6 Martin criteria for reporting complications after surgery were fulfilled. The Clavien-Dindo classification for grading complications was most frequently used. The weighted overall complication rate after RC was 34.9% (range 28.8-68.8) for in-house complications, 39.0% (range 27.3-80.0) for 30-day complications and 58.5% (range 36.1-80.5) for 90-day complications. The most common types of complications reported were gastrointestinal (29.0%) and infectious (26.4%). The weighted mortality rate was 2.4% (range 0.9-4.7) for in-house mortality, 2.1% (0.0-3.7) for 30-day mortality and 4.7% (range 0.0-7.0) for 90-day mortality. Age and comorbidity were identified as the best predictors for complications following RC.

CONCLUSION

Short-term morbidity and mortality are high following RC. Reporting of complications is heterogeneous and the quality of evidence is generally low. There is a continuous need for randomised studies to address any intervention that can reduce morbidity and mortality following RC.

Impact of clinical stage on the outcome of laparoscopic radical cystectomy: a prospective cohort study

Background

Some authors recommend not to perform laparoscopic radical cystectomy (LRC) for large bulky bladder cancer (BC) as the laparoscopic manipulation will be difficult. As there were no prospective studies focusing on the effect of the tumor stage of BC on the outcome of LRC, the aim of this prospective cohort study was to evaluate the effect of tumor stage on the outcome of LRC.

Results

LRC was completed for 47 patients. All patients were followed for at least 1 year, and there was no recurrence. COPD, DM, hypertension and renal impairment were detected, respectively, in 57.4%, 36.2%, 44.7% and 10.6% of patients. Transitional cell carcinoma and squamous cell carcinoma were found, respectively, in 91.5% and 8.5% of patients. Complications were reported in 29.78% including 29.78% Clavien grade 1, 17.02% grade 2 and 6.38% grade 3. There was no significant difference between cT2 and cT3 in perioperative criteria including demographic features, operative time, estimated blood loss, blood transfusion, pain score, hospital stay and complications. Upon final pathological assessment, 44.68% of patients were upgraded to higher pathological stages. Additional comparison was performed according to pathological stage and revealed no significant difference in the outcome of LRC between pT2 and higher stages except the pain score at first postoperative day which was higher in patients with pT3 stage.

Conclusion

LRC is a feasible and safe technique for both T2 and T3 clinical and pathological stages.

Risk factors and outcomes of myocardial injury after non-cardiac surgery in high-risk patients who underwent radical cystectomy

Radical cystectomy is considered the standard treatment for patients with muscle-invasive bladder tumors and has high postoperative complication rates among urological surgeries. High-risk patients, defined as those ≥45 years of age with history of coronary artery disease, stroke, or peripheral artery disease or those ≥65 years of age, can have a higher incidence of cardiac complications. Therefore, we evaluated the incidence, risk factors, and outcomes of myocardial injury after non-cardiac surgery (MINS) in high-risk patients who underwent radical cystectomy.This retrospective observational study analyzed 248 high-risk patients who underwent radical cystectomy. MINS was defined as serum troponin I concentration ≥0.04 mg/L within postoperative 3 days. The risk factors for MINS were evaluated by multivariate logistic regression analysis. Postoperative outcomes were evaluated. The 1-year survival after radical cystectomy was also compared between patients who developed MINS (MINS group) and those who did not (non-MINS group) by Kaplan-Meier analysis.MINS occurred in 35 patients (14.1%). Multivariate logistic regression analysis showed that early diastolic transmitral filling velocity (E)/early diastolic septal mitral annular velocity (E') ratio (odds ratio = 1.102, 95% confidence interval [1.009-1.203], P = .031) and large volume blood transfusion (odds ratio = 2.745, 95% confidence interval [1.131-6.664], P = .026) were significantly associated with MINS in high-risk patients who underwent radical cystectomy. Major adverse cardiac events and 1-year mortality were significantly higher in the MINS group than in the non-MINS group (17.1% vs 6.1%, P = .035; 28.6% vs 12.7%, P = .021, respectively). Kaplan-Meier analysis showed significantly lower 1-year survival in the MINS group than in the non-MINS group (P = .010).MINS occurred in 14.1% of patients. High E/E' ratio and large volume blood transfusion were risk factors for MINS in high-risk patients who underwent radical cystectomy. Postoperative major adverse cardiac events and 1-year mortality were significantly higher in the MINS group than in the non-MINS group. Preoperative evaluation of risk factors for MINS may provide useful information to detect cardiovascular complications after radical cystectomy in high-risk patients.

The comprehensive complication index is associated with a significant increase in complication severity between 30 and 90 days after radical cystectomy for bladder cancer

OBJECTIVE

To assess the true cumulative morbidity after RC by implementing the Comprehensive Complication Index (CCI) over a 90-day period, since recent evidence suggests underreporting of the cumulative morbidity after radical cystectomy (RC) with inconsistent complication rates when reported with conventional reporting systems.

PATIENTS AND METHODS

Medical records of 433 patients with bladder cancer who underwent RC were retrospectively reviewed over a 90-day period. Clinical variables were assessed and complications were graded by the Clavien-Dindo Classification (CDC). The resulting 30- and 90-day CCI-scores were calculated and compared for each patient. Multivariable regression models for developing at least one severe (≥CDC IIIb) complication were designed.

RESULTS

Overall, 848 complications were recorded in 371 patients (85.7%). Severe complications occurred in 130 patients (30%) and the cumulative morbidity corresponded to the level of a severe complication in 159 patients (36.7%), meaning an upgrade in 6.7% of patients compared to the CDC. The 90-day CCI (24.2 (median, IQR 20.9-39.7)) was higher than the 30-day CCI (22.6 (median, IQR 8.7-39.7)), (p < 0.001). Comorbidity indices (ASA, ACE 27), BMI, and incontinent urinary diversions were independent risk factors for suffering a severe complication within 90 days post-surgery.

CONCLUSION

The cumulative morbidity (CCI) after RC seems to be higher than previously reported with CDC, especially over a 90-day period. The CCI is an appropriate assessment-tool with an upgrade in morbidity in a significant proportion of patients when compared to the CDC. BMI, several comorbidity indices, and incontinent urinary diversions are independent risk factors for suffering a severe complication after RC.

Perioperative recovery in different urinary reconstruction approaches of radical cystectomy: Are the advantages of laparoscopy consistent?

CONTEXT

Radical cystectomy (RC) has complicated surgical procedures and various ways of urinary reconstruction.

AIMS

The aim of this study is to investigate whether the advantages of laparoscopy over open surgery were consistent in the perioperative recovery of different methods of urinary diversion after RC in the general and the elderly (>65 years) population.

SETTINGS AND DESIGN

A retrospective study reviewed 452 (elderly 261) patients who received RC from the year 2005-2012.

SUBJECTS AND METHODS

Of all, 88 patients underwent laparoscopic RC (LRC) and 364 patients underwent open RC (ORC). There were 325 patients received ileal conduit (IC), whereas 127 patients received cutaneous ureterostomy (CU).

STATISTICAL ANALYSIS USED

We used different statistical methods (t-test, Chi-square, etc.) to compare variables outcomes.

RESULTS

For IC urinary diversion, the general patients undergoing LRC had less intra-operative blood loss (566.5 vs. 1320.3 ml, P < 0.001), lower blood transfusion rate (11.4 vs. 34.1%, P < 0.001), shorter gastrointestinal recovery time (5.7 vs. 6.7 days, P= 0.002) and shorter length of hospital stay (LOS) (21.7 vs. 26.0 days, P = 0.003) than patients receiving ORC. Similar trends were observed in older patients. For CU urinary diversion, the general and the elderly patients receiving LRC had a shorter mean time to gastrointestinal recovery (P = 0.017, P < 0.001, respectively) than patients receiving ORC. No differences were found between LRC and ORC in intra-operative blood loss, allogeneic blood transfusion rate and LOS.

CONCLUSIONS

In the general and the elderly population, laparoscopic approach could result in more rapid rehabilitation for RC patients, especially in the IC patients.

Comparison of Major Complications at 30 and 90 Days Following Radical Cystectomy

OBJECTIVES

To better understand the time-course in which major complications occur after radical cystectomy and to describe associations with complications at 30 and 90 days.

METHODS

A database of radical cystectomy cases was queried for preoperative, perioperative, and postoperative data. Follow-up extended to 90 days postsurgery and included major complications (Clavien III-V). Early (30-day) and late (90-day) complication rates were compared via McNemar's test, and patient characteristics were compared across complication time groups by one-way ANOVA or Fisher's exact tests. Multinomial logistic regression was used to explore associations between patient characteristics and complication timing.

RESULTS

Of 969 patients undergoing radical cystectomy, 210/969 (21.7%) experienced a complication within 90 days. The rate of major complication significantly differed at 30 and 90 days (14.4% [conflict of interest (CI): 12.4%-16.9%] vs 21.7% [CI: 19.2%-24.4%] respectively, P ≤.0001). Chronic obstructive pulmonary disease (COPD) (P = .03), Charlson Comorbidity Index (P = .02), and Indiana pouch diversion (P = .002) were significant predictors of early complication. Diabetes was the strongest predictor for late complication (OR: 2.42; P = 0.01). Diabetes was also a significant predictor for late genitourinary complications (OR 3.39; P = .01), and smoking history was a significant predictor for late infectious complications (OR 3.61; P = .01).

CONCLUSION

We identified a significant number of complications occurring after 30 days postcystectomy, including the majority of deaths and genitourinary complications. These findings suggest that assessment of complications exclusively at 30 days would fail to capture a large proportion of major complications and deaths. Understanding the time-course of complications postcystectomy will serve to better inform design of future outcome studies.

Oncological outcome according to attainment of pentafecta after robot-assisted radical cystectomy in patients with bladder cancer included in the multicentre KORARC database

OBJECTIVES

To investigate the oncological significance of a robot-assisted radical cystectomy (RARC)-related pentafecta in patients with bladder cancer.

PATIENTS AND METHODS

Using the KORARC database, which includes data from 12 centres, data from 730 patients who underwent RARC between April 2007 and May 2019 were prospectively collected and retrospectively analysed. Pentafecta was achieved if patients met all of the following criteria: (i) negative soft tissue surgical margin; (ii) ≥16 lymph nodes removed; (iii) no major complications (Clavien-Dindo grade 3-5) within 90 days; (iv) no clinical recurrence within the first 12 months; and (v) no ureteroenteric stricture. Patients were divided into two groups according to pentafecta attainment, and a comparison of overall survival (OS) and cancer-specific survival (CSS) using multivariate Cox proportional analysis was then carried out.

RESULTS

Of the 730 patients included in this analysis, 208 (28.5%) attained the RARC pentafecta; the remaining 522 (71.5%) did not. The mean age of the patients was 64.67 years, 85.1% were men, 53.6% received a conduit, 37.7% received orthotopic neobladders and the total complication rate was 57.8%. Those who attained the pentafecta received more neobladders (P = 0.039), were more likely to be treated with the intracorporeal technique (P < 0.001), had longer operating times (P = 0.020) and had longer console time (P = 0.021) compared with those who did not attain the pentafecta. Over a mean of 31.1 months of follow-up, the pentafecta attainment group had significantly higher OS and CSS rates compared with the non-attainment group (10-year OS 70.4% vs 58.1%, respectively [P = 0.016]; 10-year CSS 87.8% vs 70.0%, respectively [P = 0.036]). Multivariate analysis showed that the RARC pentafecta was a significant predictor of overall mortality (hazard ratio 0.561; P = 0.038).

CONCLUSIONS

Patients who attained the RARC pentafecta had significantly better survival outcomes compared with those who did not. These criteria could be used to standardize assessment of the surgical quality of RARC. In the future, a similar study using an independent cohort is warranted to confirm our results.

Outcomes of Urinary Diversion for Late Adverse Effects of Gynecologic Radiotherapy

OBJECTIVE

To describe the risks of urinary diversion performed to address adverse effects of gynecologic radiation, with the hypothesis that high grade complications would be more common in sarcopenic women and in those undergoing continent diversion (vs noncontinent) or concomitant cystectomy (vs bladder-sparing diversion).

METHODS

A retrospective review was performed of patient records of women who underwent urinary diversion for urinary adverse effects of gynecologic radiotherapy during the period of 2008-2018 from 3 tertiary centers. Skeletal muscle index was calculated to assess for sarcopenia based on preoperative computed tomography scans. Outcomes include high-grade postoperative complications within 90 days of surgery, 30-day readmission rate, and long-term (>90 days) outcomes.

RESULTS

Among 34 women who met the inclusion criteria, the majority were white/Caucasian (73.5%). Twenty-six of 34 (76.5%) underwent noncontinent diversion. Seventy nine percent (27/34) (79.4%) of women experienced complications within 90 days; 9 of 34 (26.5%) experienced high-grade (Clavien grade ≥3) complications. Thirty-two percent (11/34) were readmitted within 30 days. Rates of high-grade complications were not significantly impacted by diversion type (P = .49), concurrent cystectomy (P = .70), or sarcopenia (P = 1.0).

CONCLUSIONS

Urinary diversion for late adverse effects of gynecologic radiotherapy is associated with high peri-operative risk, even in skilled hands. In this series, neither sarcopenia, nor continent diversion, nor cystectomy were associated with increased complications. Patients and surgeons should consider risks and benefits when deciding to proceed with urinary diversion, however further study is needed to elucidate significant preoperative markers which may predispose patients to significant complications.

Enhanced recovery after surgery (ERAS) protocols in patients undergoing radical cystectomy with ileal urinary diversions: A randomized controlled trial

BACKGROUND

Enhanced Recovery After Surgery (ERAS) protocols were introduced in clinical practice to reduce complication rates and hospital stay. We performed a randomized controlled single center study to evaluate perioperative benefits of an adapted ERAS protocol in patients with bladder cancer who underwent radical cystectomy (RC) and ileal urinary diversions (IUD).

MATERIALS AND METHODS

Forty five from 90 consecutive randomized patients were enrolled in an adapted ERAS protocol. Length of stay, diet issues, return of bowel function, readmission rates and complications were examined.

RESULTS

Among patients following ERAS protocol, we found a significant reduction in time to first flatus (1 vs 5 days, P < .001), time to first stool (2 vs 5 days, P < .001), time to normal diet (5 vs 6 days, P < .001) and length of stay (16 vs 18 days, P < .001). Also, postoperative ileus at less than 4 days was lower than in non-ERAS patients (15.6% vs 24.4%), but with a marginal trend toward significance (P = .05). Readmission rate was lower in the ERAS group, but the difference did not reach statistical significance. We also found a lower readmission and complication rate in patients with ERAS protocol (6.6% vs 11.1%, P = .23 and 46.6% vs 57.5%, P = .29, respectively).

CONCLUSIONS

Implementation of ERAS protocol for patients undergoing RC in our center was associated with a significant reduction in the time to the first flatus, time to the first stool, time to a normal diet, length of hospital stay.

Modified Frailty Index Predicts Postoperative Outcomes in Patients Undergoing Radical Pelvic Surgery

Patients undergoing radical pelvic surgery such as proctectomy or radical cystectomy are at risk of experiencing a variety of complications. Frailty renders patients vulnerable to adverse events. We hypothesize that frailty measured preoperatively using a validated scoring system correlates with increased likelihood of experiencing Clavien-Dindo grade IV complications and 30-day mortality and may be used as a predictive model for patients preoperatively. The NSQIP database was queried for patients who underwent proctectomy or radical cystectomy from 2008 to 2012. Pre-operative frailty was calculated using the 11-point modified frailty index (MFI). Patients were scored based on the presence of indicators and categorized into two groups (<3 or ≥3). Major postoperative morbidities and mortality were identified and analyzed in each group. 10,048 proctectomy and cystectomy patients were identified. The MFI was found to be predictive of both 30-day mortality ( P < 0.0001) and Clavien-Dindo grade IV complications ( P < 0.0001). Receiver operating characteristic analysis demonstrated improved discriminative power of the MFI with the addition of American Society of Anesthesiologists class for both prediction of complications and 30-day mortality. An MFI score of ≥3 is predictive of postoperative morbidity and mortality. Providers should be encouraged to calculate frailty preoperatively to predict adverse outcomes.

Robot-assisted intracorporeal orthotopic bladder substitution after radical cystectomy: perioperative morbidity and oncological outcomes - a single-institution experience

OBJECTIVE

To report a single-institution experience with totally intracorporeal neobladder urinary diversion (UD) after robot-assisted laparoscopic radical cystectomy (RARC).

PATIENTS AND METHODS

A total of 158 patients underwent totally intracorporeal neobladder UD after RARC between 2003 and 2016. Patient demographics, intraoperative and pathological data, 30- and 90-day perioperative mortality and complications were recorded. Complications were classified according to the modified Clavien-Dindo classification. The 5-year overall (OS) and cancer-specific survival (CSS) rates were estimated by Kaplan-Meier plots.

RESULTS

Most of the patients were male (84%) and had clinical T Stage ≤2 (87%). The mean operation time was 359 (SD ±98) min, with a median (range) estimated blood loss of 300 (50-2200) mL. Most of the men (86%) received a nerve-sparing procedure and 38% of the females an organ-sparing approach. A lymph node dissection was performed in 156 (99%) patients, with a median (range) yield of 23 (7-48) nodes. Conversion to open surgery occurred in five patients (3%). We recorded negative margins in 156 patients (99%). The median (range) follow-up was 34 (1-170) months, with 30- and 90-day mortality rates of 0%. Clavien-Dindo Grade III-IV complications occurred in 29 of 158 (18%) patients at 30-days and in eight of 158 (5%) between 30-90 days, resulting into a 90-day overall high-grade complication rate of 23%. The unadjusted estimated 5-years recurrence-free survival, CSS and OS rates were 70%, 72%, and 71%, respectively.

CONCLUSION

In our present series the complication and oncological results were similar to open RC series, suggesting that RARC followed by totally intracorporeal neobladder UD is a safe and feasible alternative.

A novel prevention bundle to reduce incisional infections after radical cystectomy

PURPOSE

Our institution implemented a novel intervention bundle to reduce incisional surgical site infections (SSIs) for patients undergoing radical cystectomy. The primary objective of this study was to evaluate the efficacy of the bundle in reducing incisional SSIs post-cystectomy.

MATERIAL AND METHODS

A before-after cohort study was performed on all patients who underwent radical cystectomy by urologic oncologists at The Ottawa Hospital from January 2016 to March 2019. Thirty-day postoperative incisional SSIs were identified from the medical record and were compared to institutionally collected National Surgical Quality Improvement Program data. The SSI reduction strategy was implemented as of March 1st, 2018. Adjusted associations between the SSI intervention with the risk of incisional SSI were determined. Cystectomy incisional SSI rates were compared to all other National Surgical Quality Improvement Program-collected surgeries at The Ottawa Hospital during the same time period.

RESULTS

One hundred and thirty-two patients were included; 41 following implementation of the SSI reduction bundle. Mean age was 69 years, 104 (79%) were male, and 59 (45%) received neobladders. The risk of incisional SSI decreased from 16.5% preintervention to 2.4% post intervention (risk ratio 0.17; P = 0.004). Intraoperative transfusion and diabetes were independently associated with an increased risk of incisional SSI (P < 0.05). The SSI rate for all other surgical procedures at our institution remained stable during the same time period.

CONCLUSIONS

The risk of SSI after radical cystectomy is high. Use of an SSI reduction bundle was associated with a large reduction in incisional SSIs. Further evaluation of this intervention in other centers is warranted.

Enhanced recovery protocol versus standard protocol for patients undergoing radical cystectomy: results of a prospective randomized study

Background

To assess patients undergoing radical cystectomy using enhanced recovery protocol and standard protocol in terms of intraoperative and postoperative outcomes and complications.

Results

All operative and postoperative complications were recorded. In group B, time to normal bowel activity ranged from 1 to 4 days, and the mean was 1.8 days (± 1.02), while it ranged from 1 to 5 days, and the mean was 3.17 days (± 1.14) in group A which was statistically significant (p value < 0.001). The length of hospital stay in group B ranged from 6 to 50 days, the mean was 13.16 days (± 7.83), while it ranged from 8 to 35 days, and the mean was 14.71 days (± 5.78) in group A which was statistically significant (p value = 0.033). Postoperative mortality was similar in both groups.

Conclusion

In patients undergoing radical cystectomy, enhanced recovery protocol is considered as a safe procedure and not associated with any increase in intraoperative and postoperative complications compared to standard protocol. The length of hospital stay and time to return to full diet are reduced.

Comparison of the Perioperative and Postoperative Outcomes of Ileal Conduit and Cutaneous Ureterostomy: A Propensity Score-Matched Analysis

INTRODUCTION

To compare perioperative and postoperative outcomes related to urinary diversion (UD) between ileal conduit and cutaneous ureterostomy following open radical cystectomy (ORC).

METHODS

This retrospective study included 232 patients with bladder cancer who underwent ORC and subsequent UD (ileal conduit, n = 123; cutaneous ureterostomy, n = 109) at Kobe University and related hospitals between January 2007 and December 2016. A propensity score method was used to adjust the preoperative status of the two groups, and the perioperative and postoperative outcomes were compared between matched cohorts. In addition, we evaluated several factors predicting renal deterioration.

RESULTS

In the matched cohorts, 87 patients were included in each group. While the operative time and postoperative fasting periods were significantly longer in patients with ileal conduit in comparison to those with cutaneous ureterostomy (both p < 0.001), there were no differences in blood loss or duration of hospitalization. Although the incidence of grade ≥III perioperative complications was similar between the two groups, the incidence of postoperative recurrent pyelonephritis in the cutaneous ureterostomy group was significantly higher than that in the ileal conduit group (25.3 and 11.4%, respectively; p = 0.030), and cutaneous ureterostomy was identified as a significant predictor of a decrease in the estimated glomerular filtration rate with an odds ratio of 2.13 (95% confidence interval, 1.19-3.85; p = 0.010).

CONCLUSIONS

The perioperative safety of ileal conduit was comparable to that of cutaneous ureterostomy, and cutaneous ureterostomy was a significant risk factor for pyelonephritis and subsequent renal deterioration, suggesting that ileal conduit may be preferable to cutaneous ureterostomy.

Venous thromboembolism after radical cystectomy and urinary diversion: a single-center experience with 1737 consecutive patients

Background: To investigate the incidence, timing, and risk factors of venous thromboembolic events (VTE) following radical cystectomy and urinary diversion in a large cohort of patients.Patients and Methods: The electronic data base of patients underwent radical cystectomy and urinary diversion in a tertiary referral center between January 2004 and February 2014 was retrospectively reviewed. Patients developed VTE namely deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days after surgery were identified and compared to those without VTE. Univariate and multivariate analyses were used to evaluate the predictors of the VTE.Results: Out of 1737 patients, 77 VTE have occurred in 70 (4%) patients. DVT and PE occurred in 34 (2%) and 43 (2.5%) patients, respectively. PE was the leading cause of mortality in 17 patients. The median (range) time for VTE was 11 days (1-92) with 39 (50.6%) events developed after the stoppage of thrombo-prophylaxis. On multivariate analysis, older age ≥60 years (OR = 1.9; p = 0.009), female gender (OR = 1.9; p = 0.02), morbid obesity (BMI ≥35 kg/m²) (OR = 2.4; p = 0.008) and preoperative platelet count (≥300.000/cc) (OR = 1.6; p = 0.045) were significant predictors for developing VTE.Conclusion: The overall incidence of VTE is 4% with more than half of events occurred after the stoppage of thromboprophylaxis highlighting the necessity of adopting an extended protocol. Independent predictors included older age, female gender, morbid obesity and preoperative thrombocytosis. These group of patients require particular attention for the prevention of this complication.

The natural history of untreated muscle-invasive bladder cancer

OBJECTIVE

To describe the natural history of untreated muscle-invasive bladder cancer (MIBC) and compare the oncological outcomes of treated and untreated patients.

PATIENTS AND METHODS

We utilised a database encompassing all patients with newly diagnosed bladder cancer in Stockholm, Sweden between 1995 and 1996. The median follow-up for survivors was 14.4 years. Overall, 538 patients were diagnosed with bladder cancer of whom 126 had clinically localised MIBC. Patients were divided into two groups: those who received radical cystectomy or radiation therapy, and those who did not receive any form of treatment. Multivariable Cox or competing-risks regressions were adopted to predict metastasis, overall survival (OS), and cancer-specific mortality (CSM), when appropriate. Analyses were adjusted for age at diagnosis, sex, tumour stage, clinical N stage, and treatment.

RESULTS

In all, 64 (51%) patients did not receive any definitive local treatment. In the untreated group, the median (interquartile range) age at diagnosis was 79 (63-83) vs 69 (63-74) years in the treated group (P < 0.001). Overall, 109 patients died during follow-up. At 6 months after diagnosis, 38% of the untreated patients had developed metastatic disease and 41% had CSM. The 5-year OS rate for untreated and treated patients was 5% (95% confidence interval [CI] 1, 12%) vs 48% (95% CI 36, 60%), respectively. Patients not receiving any treatment had a 5-year cumulative incidence of CSM of 86% (95% CI 75, 94%) vs 48% (95% CI 36, 60%) for treated patients. Untreated patients had a higher risk of progression to metastatic disease (hazard ratio [HR] 2.40, 95% CI 1.28, 4.51; P = 0.006), death from any cause (HR 2.63, 95% CI 1.65, 4.19; P < 0.001) and CSM (subdistribution HR 2.02, 95% CI 1.24, 3.30; P = 0.004).

CONCLUSIONS

Untreated patients with MIBC are at very high risk of near-term CSM. These findings may help balance the risks vs benefits of integrating curative intent therapy particularly in older patients with MIBC.

Radical cystectomy pentafecta: a proposal for standardisation of outcomes reporting following robot-assisted radical cystectomy

OBJECTIVE

To propose a standardisable composite method for reporting outcomes of radical cystectomy (RC) that incorporates both perioperative morbidity and oncological adequacy.

PATIENTS AND METHODS

From July 2010 to December 2017, 277 consecutive patients who underwent robot-assisted RC with intracorporeal urinary diversion (UD) for bladder cancer at our Institution were prospectively analysed. Patients who simultaneously demonstrated negative soft tissue surgical margins (STSMs), ≥16 lymph node (LN) yield, absence of major (grade III-IV) complications at 90 days, absence of UD-related long-term sequelae and absence of clinical recurrence at ≤12 months, were considered as having achieved the RC-pentafecta. A multivariable logistic regression model was assessed to measure predictors for achieving RC-pentafecta.

RESULTS AND LIMITATIONS

Since 2010, 270 of 277 patients that had completed at least 12 months of follow-up were included. Over a mean follow-up of 22.3 months, ≥16 LN yield, negative STSMs, absence of major complications at 90 days, and absence of UD-related surgical sequelae and clinical recurrence at ≤12 months were observed in 93.0%, 98.9%, 76.7%, 81.5% and 92.2%, patients, respectively, resulting in a RC-pentafecta rate of 53.3%. Multivariable logistic regression analysis revealed age (odds ratio [OR] 0.95; P = 0.002), type of UD (OR 2.19; P = 0.01) and pN stage (OR 0.48; P = 0.03) as independent predictors for achieving RC-pentafecta.

CONCLUSIONS

We present a RC-pentafecta as a standardisable composite endpoint that incorporates perioperative morbidity and oncological adequacy as a potential tool to assess quality of RC. This tool may be useful for assessing the learning curve and calculating cost-effectiveness amongst others but needs to be externally validated in future studies.

Prospective, randomized clinical trial comparing use of intraoperative transesophageal echocardiography to standard care during radical cystectomy

Purpose:

Our prospective, randomized clinical study aims to evaluate the utility of intraoperative transesophageal echocardiography (TEE) in patients undergoing radical cystectomy.

Materials and Methods:

Eighty patients were randomized to a standard of care group or the intervention group that received continuous intraoperative TEE. Data are presented as means ± standard deviations, median (25^th percentile, 75^th percentile), or numbers and percentages. Characteristics were compared between groups using independent sample t-tests, Wilcoxon–Mann–Whitney tests or Chi-square tests, as appropriate. All tests were two-sided and P < 0.05 was considered to indicate statistical significance.

Results:

Both groups had similar preoperative demographic characteristics. There was a significant difference between central line insertion with all insertions in the control group (15%, 6 vs. 0%, 0; P < 0.003). Of all the perioperative complications, 80% occurred in the control group versus 20% in the TEE group, with 21% of controls experiencing a cardiac or pulmonary complication compared to 5% in the TEE group (8 vs. 2, P < 0.04). The control group patients were more likely to have adverse cardiac complications than the TEE group (15%, 6 vs. 3%, 1; P < 0.040). Postoperative cardiac arrhythmia was observed only in the control group (13%, 5 vs. 0%, 0; P <.007). Prolonged intubation was only observed in the control group (10%, 4 vs. 0%, 0; P < 0.017).

Conclusion:

TEE can be a useful monitoring tool in patients undergoing radical cystectomy, limiting the use of central line insertion and potentially translating into earlier extubation and decreased postoperative cardiac morbidities.

Management of Patients with Liver Cirrhosis and Invasive Bladder Cancer: A Case-series

Liver cirrhosis is a major risk factor for increased mortality and morbidity in patients undergoing non-hepatic surgery with overall mortality rates as high as 45–50%. However, cirrhotic patients are often in need of surgical procedures including urological surgeries like cystectomies for muscle invasive bladder cancer. Data on the prognosis of these patients undergoing cystectomy for bladder cancer are scarce in the literature. In the present case-study, we describe the outcomes of 3 patients with liver cirrhosis who underwent radical cystectomy for muscle invasive bladder cancer. To the best of our knowledge, this is the first study reporting on this kind of urological surgery in patients with liver cirrhosis. Accordingly, we provide a review in the literature on prognosis and factors influencing the survival of cirrhotic patients who undergo surgical procedures.

A multi-institutional study of bladder-preserving therapy for stage II-IV bladder cancer: A Korean Radiation Oncology Group Study (KROG 14-16)

Background

Although radical cystectomy is a standard treatment in muscle-invasive bladder cancer, bladder preservation therapy including transurethral resection of bladder tumor, radiotherapy, and concurrent chemotherapy has been widely adopted, recently. This retrospective analysis was performed to evaluate the survival rates and prognostic factors related to treatment outcomes following bladder-preserving therapy including radiotherapy (RT) in bladder cancer with a curative intent.

Materials and methods

We conducted a multi-institutional retrospective study of 152 patients with stage II-IV bladder cancer treated with curative RT between 2000 and 2010. There were 72 patients in stage II, 49 in stage III, and 31 in stage IV. Ninety-seven patients were treated with concurrent chemoradiotherapy and fifty-five with RT alone. Radiation was delivered to the pelvis (median 63 Gy), mainly with cisplatin. The median follow-up time was 35.5 months.

Results

Sixty-nine patients (45.4%) showed a complete response to RT. The 5-year overall survival (OS) rate was 45.8%, the 5-year cause-specific survival (CSS) rate was 48.9%, and the 5-year disease-free survival (DFS) rate was 20.8%. Univariate analysis revealed significant differences in the following factors according to the survival rates: patient age, initial hemoglobin level, clinical T stage, clinical N stage, clinical stage group, tumor response to RT, hydronephrosis, and concurrent chemotherapy. Multivariate analysis also revealed a significant difference in patient age (p = 0.003 in OS, p<0.017 in CSS) and tumor response to RT (p = 0.002 in OS, p<0.001 in CSS). Concurrent chemotherapy was significantly different in the DFS rates (p = 0.046).

Conclusions

The survival rates reported herein are comparable to those from other studies, and tumor response and concurrent chemoradiotherapy were significant prognostic factors for better survival rates. Further randomized studies are needed to elucidate the impact of RT in bladder cancer.

The Comprehensive Complication Index CCI: A proposed modification to optimize short-term complication reporting after cystectomy and urinary diversion

OBJECTIVE

To optimize complication reporting in patients undergoing cystectomy and urinary diversion (UD) using the Comprehensive Complication Index (CCI). The original CCI ranging from 0 (no complications) to 100 (death) integrates all complications weighted by severity over time in a single formula. However, due to the large number of complications after cystectomy and UD, the CCI may exceed the upper limit.

METHODS

In an observational single-center cohort, 90-day postoperative complications in 1,313 consecutive patients undergoing cystectomy and UD from 2000 to 2017 were evaluated. Prospectively collected complications were graded according to the Clavien-Dindo classification (CDC). A modified Berne CCI was developed using an exponential function, which transforms the sum of the weights into a value between 0 and 100. The correlation between the Berne and original CCI values was depicted graphically. Finally, original CCI and Berne CCI values for each patient were extracted and compared. Predictive values of CCI scores for mortality or severe complications (CDC ≥IV) within 1 year postoperatively were investigated by use of multiple logistic regression analyses.

RESULTS

Overall complication rate was 82%, with CDC grade I to II in 56% and CDC grade IIIa to V in 27% respectively. Applying the original CCI, the upper limit was exceeded in 8 patients, with a maximal value of 119.1 (median 25.7 [interquartile range: 20.9-37.2]). The maximal value of the Berne CCI was 99.4 (21.2 [14.6-39.3]) for nondeath cases. The Berne CCI predicted the onset of death and severe complications between postoperative day 91 and 365 (both P <0.0001), whereas the original CCI was only predictive in interaction with other variables but not alone (P = 0.2772 and P = 0.0862, respectively).

CONCLUSION

The optimized Berne CCI depicts postoperative morbidity and burden within 90 days after cystectomy and UD without exceeding the upper index limit. It is specifically suited for longitudinal assessment of complications after cystectomy and UD taking into consideration every single complication and corresponding treatment. As the Berne CCI well predicted the onset of mortality and severe complications within 1 year postoperatively, this may allow a better preoperative patient counselling. It therefore warrants consideration for standardized reporting of complications after cystectomy and UD.
