RESUMO

OBJECTIVE: To determine if the timing of radical cystectomy for variant histology of urothelial carcinoma has an impact on survival. Variant histology has been associated with aberrant behavior compared to pure urothelial carcinoma, however the timing of surgery for these patients has not been studied. MATERIALS AND METHODS: We identified 363 patients with cT2-T4N0M0 urothelial carcinoma who underwent radical cystectomy without perioperative intravesical and/or systemic therapy from 2003 to 2014. Clinicopathologic data was compared between pure urothelial carcinoma and variant histology. The time from diagnosis to radical cystectomy was analyzed as a continuous variable and dichotomized at 4-, 8-, and 12-weeks to determine impact on oncologic outcomes. RESULTS: Patients with variant histology, when compared to those with pure urothelial carcinoma, were more likely to present with extravesical disease (p<0.01), be upstaged (p<0.01), have lymphovascular invasion (p<0.01) and have lymph node metastasis at radical cystectomy (p=0.02). The median days to radical cystectomy did not differ between pure urothelial and variant histology. On multivariable analysis controlling for age, comorbidities, tumor stage, lymph node status, lymphovascular invasion, and surgical margins, every month in delay was associated with a worse overall survival for variants (HR=1.36, p=0.003). At an 8-week delay or longer, those with variant histology had a statistically worse survival (p=0.03). CONCLUSIONS: For patients with variant histology, delays in surgery were associated with an increased risk of death.

RESUMO

The introduction of cisplatin-based chemotherapy has revolutionized the care of patients with disseminated testicular germ cell tumors. Although a majority are cured with chemotherapy alone, surgical resection continues to play a role because one-third will have residual mass after chemotherapy. In this article, we review the current indications for postchemotherapy resection in nonseminomatous germ cell tumors, including masses greater than 1 cm, resection after salvage chemotherapy, with elevated markers, after late relapse, and for growing teratoma syndrome. We also highlight technical considerations of this often-challenging surgery, including the need for adjunctive procedures, extraretroperitoneal resections, and modern techniques to minimize morbidity.

RESUMO

OBJECTIVES: To evaluate the effects of surgeon experience, body habitus, and bony pelvic dimensions on surgeon performance and patient outcomes after robot-assisted radical prostatectomy (RARP). PATIENTS, SUBJECTS AND METHODS: The pelvic dimensions of 78 RARP patients were measured on preoperative magnetic resonance imaging and computed tomography by three radiologists. Surgeon automated performance metrics (APMs [instrument motion tracking and system events data, i.e., camera movement, third-arm swap, energy use]) were obtained by a systems data recorder (Intuitive Surgical, Sunnyvale, CA, USA) during RARP. Two analyses were performed: Analysis 1, examined effects of patient characteristics, pelvic dimensions and prior surgeon RARP caseload on APMs using linear regression; Analysis 2, the effects of patient body habitus, bony pelvic measurement, and surgeon experience on short- and long-term outcomes were analysed by multivariable regression. RESULTS: Analysis 1 showed that while surgeon experience affected the greatest number of APMs (P < 0.044), the patient's body mass index, bony pelvic dimensions, and prostate size also affected APMs during each surgical step (P < 0.043, P < 0.046, P < 0.034, respectively). Analysis 2 showed that RARP duration was significantly affected by pelvic depth (ß = 13.7, P = 0.039) and prostate volume (ß = 0.5, P = 0.024). A wider and shallower pelvis was less likely to result in a positive margin (odds ratio 0.25, 95% confidence interval [CI] 0.09-0.72). On multivariate analysis, urinary continence recovery was associated with surgeon's prior RARP experience (hazard ratio [HR] 2.38, 95% CI 1.18-4.81; P = 0.015), but not on pelvic dimensions (HR 1.44, 95% CI 0.95-2.17). CONCLUSION: Limited surgical workspace, due to a narrower and deeper pelvis, does affect surgeon performance and patient outcomes, most notably in longer surgery time and an increased positive margin rate.

RESUMO

PURPOSE: In this study, we investigate the ability of automated performance metrics (APMs) and task-evoked pupillary response (TEPR), as objective measures of surgeon performance, to distinguish varying levels of surgeon expertise during generic robotic surgical tasks. Additionally, we evaluate the association between APMs and TEPR. METHODS: Participants completed ten tasks on a da Vinci Xi Surgical System (Intuitive Surgical, Inc.), each representing a surgical skill type: EndoWrist® manipulation, needle targeting, suturing/knot tying, and excision/dissection. Automated performance metrics (instrument motion tracking, EndoWrist® articulation, and system events data) and TEPR were recorded by a systems data recorder (Intuitive Surgical, Inc.) and Tobii Pro Glasses 2 (Tobii Technologies, Inc.), respectively. The Kruskal-Wallis test determined significant differences between groups of varying expertise. Spearman's rank correlation coefficient measured associations between APMs and TEPR. RESULTS: Twenty-six participants were stratified by robotic surgical experience: novice (no prior experience; n = 9), intermediate (< 100 cases; n = 9), and experts (≥ 100 cases; n = 8). Several APMs differentiated surgeon experience including task duration (p < 0.01), time active of instruments (p < 0.03), linear velocity of instruments (p < 0.04), and angular velocity of dominant instrument (p < 0.04). Task-evoked pupillary response distinguished surgeon expertise for three out of four task types (p < 0.04). Correlation trends between APMs and TEPR revealed that expert surgeons move more slowly with high cognitive workload (ρ < - 0.60, p < 0.05), while novices move faster under the same cognitive experiences (ρ > 0.66, p < 0.05). CONCLUSIONS: Automated performance metrics and TEPR can distinguish surgeon expertise levels during robotic surgical tasks. Furthermore, under high cognitive workload, there can be a divergence in robotic movement profiles between expertise levels.

RESUMO

PURPOSE: To determine whether surgical approach is a determinant of clinical outcomes following radical cystectomy (RC) and urinary diversion when using an Enhanced Recovery After Surgery (ERAS) protocol. MATERIALS AND METHODS: We studied all patients undergoing both open radical cystectomy (ORC) and robotic-assisted radical cystectomy (RARC) and urinary diversion with ERAS for bladder urothelial carcinoma from May 2012 to December 2016. Surgical and clinical outcomes within 90 days after surgery were compared between ORC and RARC, including readmission and major complication rates (Clavien-Dindo grade ≥III). Multivariable logistic regression modeling was used to determine factors that predict readmission and major complications. RESULTS: A total of 345 and 143 patients underwent ORC and RARC, respectively. The ORC group had a greater proportion of continent urinary diversion (71.9 vs. 40.6%, P< 0.001), shorter operative time (5.4 vs. 7.3 hours, P< 0.001), higher estimated blood loss (500 vs. 200 ml, P< 0.001), and higher intraoperative and postoperative transfusion rates (20.9 vs. 9.1%, P= 0.002 and 20 vs. 11.9%, P= 0.04, respectively). Median length of stay was 4 days for ORC (interquartile range 4-6 days) and 6 days for RARC (interquartile range 4-7 days; P< 0.001). There was no significant difference between ORC and RARC groups in major complication rates (20 vs. 23.8%, P= 0.51) or readmission rates (32.2 vs. 36.4%, P= 0.4) within 90 days after surgery. Multivariable logistic regression analysis showed that surgical approach was not an independent factor predictive of readmission (P= 0.33) or major complications (P= 0.76). CONCLUSIONS: Surgical approach is not a determinant of readmission or major complications following RC in the context of an ERAS protocol.

RESUMO

OBJECTIVES: Bladder cancer is the fourth most common cancer among males and poses a significant financial burden, yet there are no large-scale studies focused on the correlation between socioeconomic (SES) and insurance status and bladder cancer outcomes. The objective of this study was to determine the effect of SES and insurance type on outcomes in bladder cancer. MATERIALS AND METHODS: A population-based search was performed using the National Cancer Institute's Surveillance, Epidemiology, and End Results 18 database. Patients aged 18 or older and diagnosed with bladder cancer between 2011 and 2015 were identified. Data on patient demographics, SES features, insurance status, tumor characteristics, and survival were collected. A county-level SES measure was created in a method consistent with prior literature. Primary outcomes were overall survival (OS) and disease-specific survival (DSS). RESULTS: A total of 91,308 patients were identified. Factors predictive of having muscle invasive disease included having Medicaid insurance, having no insurance, and being in the lowest SES quartile (all P < 0.001). Having Medicaid or no insurance was predictive of having node positive or metastatic disease (P < 0.001). Independent of T stage, patients in the lowest and second lowest SES quartiles had worse OS (P = 0.004 and P = 0.022, respectively) and DSS (P < 0.001 for both). Patients with Medicaid or no insurance had worse OS and DSS (P < 0.001 for all). CONCLUSIONS: Lower SES status, Medicaid insurance, and having no insurance were all predictive of having higher tumor stage. Independent of tumor stage, being of lower SES, having Medicaid insurance, and having no insurance predicted worse OS and DSS.

RESUMO

OBJECTIVE: To define clinical features and surgical management of urethro-cavernosal fistulas (UCF). METHODS: A literature search was performed using PubMed to identify publications with the key word urethro-cavernosal fistula. RESULTS: We herein describe surgical techniques and long-term outcomes for UCF repair. CONCLUSION: UCFs is a rare urological condition with only 9 cases reported to date. UCFs can be diagnosed with careful history, physical examination, and retrograde urethrography. Surgical management includes basic tenets of fistula repair, including adequate mobilization, tension-free but watertight approximation, multilayered closure with nonoverlapping suture lines, and maximal bladder drainage.

RESUMO

OBJECTIVES: To predict urinary continence recovery after robot-assisted radical prostatectomy (RARP) using a deep learning (DL) model, which was then used to evaluate surgeon's historical patient outcomes. SUBJECTS AND METHODS: Robotic surgical automated performance metrics (APMs) during RARP, and patient clinicopathological and continence data were captured prospectively from 100 contemporary RARPs. We used a DL model (DeepSurv) to predict postoperative urinary continence. Model features were ranked based on their importance in prediction. We stratified eight surgeons based on the five top-ranked features. The top four surgeons were categorized in 'Group 1/APMs', while the remaining four were categorized in 'Group 2/APMs'. A separate historical cohort of RARPs (January 2015 to August 2016) performed by these two surgeon groups was then used for comparison. Concordance index (C-index) and mean absolute error (MAE) were used to measure the model's prediction performance. Outcomes of historical cases were compared using the Kruskal-Wallis, chi-squared and Fisher's exact tests. RESULTS: Continence was attained in 79 patients (79%) after a median of 126 days. The DL model achieved a C-index of 0.6 and an MAE of 85.9 in predicting continence. APMs were ranked higher by the model than clinicopathological features. In the historical cohort, patients in Group 1/APMs had superior rates of urinary continence at 3 and 6 months postoperatively (47.5 vs 36.7%, P = 0.034, and 68.3 vs 59.2%, P = 0.047, respectively). CONCLUSION: Using APMs and clinicopathological data, the DeepSurv DL model was able to predict continence after RARP. In this feasibility study, surgeons with more efficient APMs achieved higher continence rates at 3 and 6 months after RARP.

RESUMO

PURPOSE OF REVIEW: Our aim is to review recent investigations into the recurrence of urothelial carcinoma in the upper urinary tract following bladder cancer therapy focusing on surveillance and management. RECENT FINDINGS: After radical cystectomy, rates of recurrence in the upper tract are between 0.75 and 6.4%. The poor prognosis of upper tract urothelial carcinoma (UTUC) is in part attributable to delayed diagnosis. Guidelines recommend a gradual de-escalation of surveillance in disease-free patients with the potential for discontinuation beyond 5 years. Previous guideline audits have shown that recurrences are still missed, suggesting a need for longer follow-up. Studies propose risk stratifying patients by age, comorbidities, and tumor stage to warrant closer surveillance and identify adjuvant therapy candidates. Larger studies are needed to advise treatment of UTUC after a urothelial bladder cancer (UBC) diagnosis, as these patients face poorer outcomes following radical nephroureterectomy. Clinical trials have demonstrated the efficacy of neoadjuvant and adjuvant systemic therapy after radical nephroureterectomy for primary UTUC; however, the literature is lacking robust data on patients who develop urothelial carcinoma in the upper tract following an initial UBC diagnosis. SUMMARY: Many asymptomatic recurrences of urothelial carcinoma in the upper tract are undetected by current surveillance guideline recommendations. Higher level evidence is needed to confirm the efficacy of prolonged and risk-adapted surveillance of patients with UBC and the extirpative management of recurrence in the upper tract after UBC treatment.

RESUMO

INTRODUCTION: To evaluate the reasons leading to an extended hospital stay (EHS) in patients undergoing radical cystectomy (RC) with postoperative enhanced recovery after surgery (ERAS) protocol. MATERIALS AND METHODS: A total of 509 patients underwent RC and urinary diversion with ERAS between May 2012 and March 2017. The protocol includes no bowel preparation, early feeding, predominantly non-narcotic pain control and µ opioid antagonists. Non-consenting/lost to follow up patients, and those with non-urothelial carcinoma were excluded. We defined EHS as ≥ 5 postoperative days and compared the cohort to those with a LOS of ≤ 4 days. Demographics including modifiable and non-modifiable factors as well as in-house complications as possible contributing factors to EHS was reviewed. RESULTS: There were 279/509 (54.8%) patients had an EHS. Median age was 73 years, 82.4% were male, and 36.6% had a Charlson comorbidity index (CCI) of > 2. Univariate analysis demonstrated that age > 65 years, CCI > 2, increased operative time, anemia requiring transfusion and non-orthotopic diversion were associated with EHS. On multivariate analysis, advanced age, operative time, postop transfusion, CCI > 2 as well as surgeon specific preferences was associated with EHS. Within EHS patients, 86% stayed due to an in-house complication; ileus (34.3%), anemia requiring transfusion (9.8%), UTIs (9.4%) and atrial fibrillation (8.5%). CONCLUSIONS: Advanced age, operative time, postop transfusion, CCI > 2 and surgeon-specific preferences are associated with an EHS following RC with ERAS. The common causes of EHS are in-house complications, mainly ileus.

RESUMO

OBJECTIVES: To determine the impact of radical cystectomy and orthotopic neobladder (NB) diversion on device-related outcomes in patients who undergo subsequent placement of both, an artificial urinary sphincter (AUS) and 3-piece inflatable penile prosthesis. MATERIALS AND METHODS: Using an institutional prosthetic database, we identified 39 patients who underwent radical cystectomy and NB and subsequent implantation of both prosthetic devices from 2003 to 2017. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection, mechanical failure, revision surgery, and functional outcomes were examined and compared to an appropriate matched group of patients (n = 48, non-neobladder group). RESULTS: No intraoperative complications were observed. After median follow-up of 94 months (12-177 months), 1 patient developed an infection of their penile prosthesis and 4 patients developed an erosion of their AUS. In each case, the infection did not involve the other device. Two patients required revision surgery of their penile prosthesis due to mechanical failure (reservoir leak, n = 1; cylinder aneurysm, n = 1). Twenty-one patients underwent elective revision surgery to improve continence (cuff downsizing, n = 18; pressure-regulating balloon exchange, n = 3). There were 6 cases of AUS mechanical failure. No reservoir-related complications such as herniation or erosion were observed. Compared to the control group of non-neobladder patients, there were no significant differences in prosthetic infection, mechanical failure, and revision surgery. CONCLUSION: The AUS and 3-piece inflatable penile prosthesis can coexist safely in patients with NB without an increased risk of device-related complications.

RESUMO

OBJECTIVES: To determine and investigate the intraoperative factors that contribute to a change in plan from continent orthotopic neobladder to ileal conduit or continent cutaneous diversion at the time of radical cystectomy. SUBJECTS AND METHODS: A retrospective review of our prospectively maintained bladder cancer database was performed. Of the 711 patients who underwent radical cystectomy from 2012 to 2016, 387 (54.4%) had given consent to have a NB. Of these 387 patients, 348 (89.9%) ultimately received a neobladder while 34 (8.8%) received an ileal conduit and 5 (1.3%) continent cutaneous diversion. The factors involved in the intraoperative change of plan were examined in this study. RESULTS: Patients who ultimately received a neobladder were significantly more likely to have clinical node-negative disease (p = 0.045), negative soft tissue margins (p = 0.001), lower body mass index (p = 0.045) and higher volume surgeons (p < 0.001). Oncologic reasons for intraoperative conversions were more common than technical reasons (58.3% vs 35.9%), in both robotic and open surgical techniques. The choice of surgical approach (open vs robotic) did not influence the rate of intraoperative conversion. CONCLUSION: The factors influencing intraoperative decision not to perform neobladder are predominantly oncologic rather than technical. A clear understanding of the factors involved in influencing the intraoperative change in the urinary diversion plan may improve shared decision making in patients undergoing radical cystectomy in the future.

RESUMO

OBJECTIVES: To evaluate automated performance metrics (APMs) and clinical data of experts and super-experts for four cardinal steps of robot-assisted radical prostatectomy (RARP): bladder neck dissection; pedicle dissection; prostate apex dissection; and vesico-urethral anastomosis. SUBJECTS AND METHODS: We captured APMs (motion tracking and system events data) and synchronized surgical video during RARP. APMs were compared between two experience levels: experts (100-750 cases) and super-experts (2100-3500 cases). Clinical outcomes (peri-operative, oncological and functional) were then compared between the two groups. APMs and outcomes were analysed for 125 RARPs using multi-level mixed-effect modelling. RESULTS: For the four cardinal steps selected, super-experts showed differences in select APMs compared with experts (P < 0.05). Despite similar PSA and Gleason scores, super-experts outperformed experts clinically with regard to peri-operative outcomes, with a greater lymph node yield of 22.6 vs 14.9 nodes, respectively (P < 0.01), less blood loss (125 vs 130 mL, respectively; P < 0.01), and fewer readmissions at 30 days (1% vs 13%, respectively; P = 0.02). A similar but nonsignificant trend was seen for oncological and functional outcomes, with super-experts having a lower rate of biochemical recurrence compared with experts (5% vs 15%, respectively; P = 0.13) and a higher continence rate at 3 months (36% vs 18%, respectively; P = 0.14). CONCLUSION: We found that experts and super-experts differed significantly in select APMs for the four cardinal steps of RARP, indicating that surgeons do continue to improve in performance even after achieving expertise. We hope ultimately to identify associations between APMs and clinical outcomes to tailor interventions to surgeons and optimize patient outcomes.

RESUMO

PURPOSE OF REVIEW: The purpose of the study is to review and summarize major additions to the literature as pertains to enhanced recovery protocols after radical cystectomy in the past year. RECENT FINDINGS: Enhanced recovery after surgery protocols is multimodal pathways that include elements to optimize all stages of care including preoperative, intraoperative and postoperative measures. Several authors have recently presented their results with initial implementation of an enhanced recovery protocol after radical cystectomy, while others have begun to examine outcomes beyond the index admission and to refine the various targeted components of the protocol. Enhanced recovery after surgery protocols has revolutionized patient care following radical cystectomy, a procedure still burdened by high complication rates and lengthy hospital stay. Although still lacking in universal implementation and standardization of the protocol, significant advancements are made each year as we move towards best practice.

RESUMO

Significant evidence exists regarding the diagnostic and therapeutic roles of pelvic lymph node dissection at the time of radical cystectomy for patients with bladder cancer. Despite this, lymphadenectomy for bladder cancer is still underutilized and even where performed, controversies exist in regard to what defines an adequate dissection and whether or not the indications for lymphadenectomy have changed now that we are firmly entrenched in the neoadjuvant chemotherapy era. A comprehensive literature review was performed to touch on these important issues and highlight future directions and current trials that will soon provide more clarity for surgeons and patients dealing with bladder cancer.

RESUMO

Paratesticular serous papillary carcinomas are very rare, with less than 40 cases reported in the literature. These neoplasms are Müllerian in origin, and more commonly seen as epithelial-type ovarian cancer. Given the rarity of this tumor in men, staging and recommended treatment options do not exist. Herein, we present the case of a 35-year-old male with high-grade invasive serous papillary carcinoma. He was diagnosed after left radical orchiectomy for paratesticular mass and subsequently treated with adjuvant chemotherapy according to existing recommendations for its ovarian counterpart. Chemotherapy was well tolerated and surveillance imaging has shown no evidence of disease. This case suggests a potential role for adjuvant therapy in patients with high-grade paratesticular serous papillary carcinoma.

RESUMO

PURPOSE: To evaluate the association between intraoperative fluid intake and postoperative complications in patients who underwent radical cystectomy (RC) for bladder cancer with an enhanced recovery protocol. METHODS: 287 patients underwent open RC with enhanced recovery protocol (ERAS) from 2012 to 2016. 107 were excluded; non-urothelial (30), palliative (37), had adjunct procedures or not-consented (40). We prospectively evaluated intraoperative fluid intake (crystalloid, colloid and blood) and correlated with length of stay, 30- and 90-day complications. RESULTS: 180 patients enrolled into the study with median age of 70 years (78% male). 71% underwent orthotopic diversion. Median intraoperative crystalloid and colloid intake were 4000 and 500 cc, respectively. Nineteen percent of patients received blood transfusion. Median length of stay was 4 days. The overall 30- and 90-day complication rates were 59 and 75%, respectively. Multivariate logistic regressions controlling for a subset of clinically relevant variables showed no significant association between intraoperative fluid intake and complications at 30 or 90 days (p = 0.88 and 0.62, respectively). A multivariable linear regression similarly showed no association between total intraoperative fluid intake and length of stay (p = 0.099). CONCLUSION: Higher intraoperative fluid intake was not found to independently increase the complication rate following radical cystectomy. Larger studies and prospective trials are needed to determine if fluid optimization may play a role in decreasing morbidity after this major surgery.
