RESUMO

OBJECTIVE: To examine the timing, patterns and predictors of 90-day readmission after robotic radical cystectomy. METHODS: From September 2009 to March 2017, 271 consecutive patients undergoing robotic radical cystectomy (RRC) with intent to cure bladder cancer (intracorporeal diversion N=253, 93%) were identified from our prospectively collated institutional database. Readmission was defined as any subsequent inpatient admission or unplanned visit occurring within 90-days from discharge after the index hospitalization. Multiple readmissions were defined as ≥ 2 readmissions within 90-days period. Logistic regression analysis was used to identify independent factors related to single and multiple 90-days readmission. RESULTS: A total of 78 (28.8%) patients were readmitted at least once within 90-days after discharge of whom 20 (25.6%) patients reported multiple readmissions. The cumulative duration of readmission was 6.2 (6.17) days with 6 (7.6%) patients having <24 hours readmission. Metabolic, infectious, genitourinary and gastrointestinal complications were identified as primary cause of readmission in 39.5%, 23.5%, 22.3% and 17%, respectively. Fifty percent readmissions occurred in the first two weeks after hospital discharge. On multivariable logistic-regression analysis, in-hospital infections (OR:2.85;p=0.001) were independent predictors for overall readmission. Male gender (OR:3.5; p=0.02) and in hospital infections (OR:4.35;p=0.002) were independent predictors for multiple readmissions. CONCLUSION: The 90-day readmission rate following robotic radical cystectomy is significant. In-hospital infections and male gender were independent factors for readmission. Most readmissions occurred in the first 2 weeks following discharge, with metabolic derrangements and infections being the most common causes.

RESUMO

PURPOSE: To evaluate pathologic downstaging after radical cystectomy and pelvic lymph node dissection for clinically lymph node positive urothelial bladder cancer and to determine optimal preoperative imaging variables in predicting pathologic nodal status. METHODS: We identified all patients with clinically lymph node positive urothelial bladder cancer who underwent radical cystectomy and extended pelvic lymph node dissection with intent to cure at our institution. Patients were stratified based on pathologic node status to determine clinical associations and survival outcomes. Pre and post-chemotherapy CT scans were reviewed to characterize lymph node size and morphology. We also sought to determine associations between post-chemotherapy radiology variables and pathologic response. RESULTS: We identified 130 patients with clinically node positive bladder cancer, out of which 76 (58.5%) received induction chemotherapy. Thirty three (43.4%) had pathologic T downstaging following chemotherapy, compared to 7 (12.9%) patients who had surgery alone (P< 0.0001). A complete nodal response (pN0) occurred in 31 (40.8%) patients post-chemotherapy, while 6 (11.1%) of those who received cystectomy alone ended up being pN0 (P< 0.0001). Median overall survival and recurrence-free survival were shorter in patients with pN+ versus pN0 disease (1.9 years vs. 12.8 years, P= 0.016 and 1.2 years vs. 4.3 years, P= 0.013, respectively). Review of 29 post chemotherapy CT scans showed that patients with pathologic nodal involvement had a greater median number of enlarged nodes (3.5 vs. 1, P= 0.038) and a greater median size of largest node (8.5 mm vs. 6.0 mm, P= 0.021) on imaging compared to those with complete pN0. Each 1 mm increase in size of the largest node on post-chemotherapy CT scan increased the chance of having pN+ disease by 1.57 (95% CI 1.02-2.44, P= 0.043). Using a median node size of 8 mm as a cut-off to predict pN+ disease provided a sensitivity and specificity of 72% and 80%, respectively (c-index = 0.761, P= 0.014). The positive predictive value for this cut-off was 87% (95% CI 58%-98%) and negative predictive value was 62% (32%-85%). CONCLUSION: Patients with clinically node positive bladder cancer may have significant pN0 after induction chemotherapy. Our data suggest a post-chemotherapy CT scan with an 8 mm nodal size cut-off may be a better predictor of pathologic nodal status than more traditional measures.

RESUMO

OBJECTIVES: To evaluate the complications and oncologic outcomes of orthotopic ileal neobladder reconstruction (ONB) following pelvic radiotherapy (RT) compared to patients with no prior pelvic RT. METHODS: Our institutional database was queried for all patients with pT0-4bN0-3M0 urothelial carcinoma of the bladder who underwent radical cystectomy with curative intent and ONB between 1990 and 2018. We then queried this cohort for patients who had prior pelvic RT (>3900 cGy) and compared baseline characteristics, perioperative complications, and recurrence free survival between patients with and without prior pelvic RT. RESULTS: One thousand eight hundred and forty-six patients matched our inclusion criteria; 34 had prior pelvic RT with a median dose of 6280 cGy. Prior RT targeted the bladder, prostate, and cervix in 27, 6, and 1 patient, respectively. Median time from RT to cystectomy was 15.5 months. Patients with prior RT had a longer time from diagnosis to cystectomy, more frequently had ≥5 TURBT and neoadjuvant chemo, and less frequently had multifocal disease. Perioperative complications including operative time, estimated blood loss, days hospitalized, as well as 30- and 90-day complication rates, were not statistically different. There was no statistical difference in recurrence free survival between the 2 groups (P = .48). CONCLUSION: ONB in highly selected patients with prior pelvic RT is feasible with statistically similar perioperative complication rates compared to ONB without prior RT.

RESUMO

Clear cell renal cell carcinoma is associated with calcium deposition in a significant percentage of patients. However, frank ossification within a tumor is extremely rare. We report a case of a 41-year-old male with a slow-growing left renal mass who underwent minimally invasive nephron-sparing surgery. Final pathology revealed clear cell renal cell carcinoma with focal areas of heterotopic bone formation. While prognostic implications of this variant are unclear, patients with renal cell carcinoma with osseous metaplasia can present with slow growth kinetics and early-stage disease.

RESUMO

OBJECTIVES: To evaluate the risk of occult nodal metastasis in patients with muscle invasive bladder cancer who exhibit a complete or partial clinical response to neoadjuvant chemotherapy (NAC) and assess a potential role for "bladder sparing" management given that the gold standard treatment, radical cystectomy (RC), is associated with high morbidity. METHODS: We queried the National Cancer Database for bladder cancer from 2004 to 2013 including patients with cT2-4aN0M0 bladder cancer who underwent multiagent NAC followed by RC and pelvic lymphadenectomy and excluding patients with nonurothelial predominant histology and those undergoing partial cystectomy. Student's t test was used to evaluate patients' demographics, presence of co-morbid conditions, and pathologic findings, notably the presence of lymphovascular invasion and variant histology. RESULTS: We identified 17,917 patients who underwent RC. Of these, 14.9% (n = 2673) received NAC before RC. About 13.1% and 14.5% of patients had complete (ypT0) and partial (ypTa, Tis, and T1) pathologic response, respectively. These 14.7% of cT2, 9.0% of cT3, and 6.9% of cT4 patients exhibited pT0 status on final pathology. And 4.9% of complete and 5.4% of partial responders demonstrated occult nodal metastases. Age, sex, ethnicity, the presence of co-morbidities, LVI, and variant histology were not significantly associated with occult nodal metastasis. CONCLUSION: While bladder preservation may be a viable option in patients who are carefully selected and closely followed after NAC, patients undergoing NAC may be at risk of occult disease outside of the bladder despite an otherwise clinical complete response diagnosed with cross-sectional imaging, cystoscopy, TURBT, and cytology.

RESUMO

BACKGROUND: The perception of penile length loss is common in male patients undergoing radical prostatectomy; however, this has not been described after radical cystoprostatectomy (RC). AIM: To evaluate perceptions of penile length loss in male patients after RC and contributing factors. METHODS: Patients completed an institutional review board-approved questionnaire comprised the International Index of Erectile Function (IIEF-5) and supplemental questions including perceived changes in penile length after RC. Multivariable analysis was performed to determine associations between the perception of penile length loss and the amount of length lost with patient and surgery-specific factors. OUTCOMES: The rate of patient-reported penile length loss and factors contributing to this perception was the outcome of this study. RESULTS: From October 2017 to January 2019, 151 patients completed the questionnaire. The median age at cystectomy was 66.1 years (interquartile range [IQR]: 59.4-73.3), and the median duration of follow-up was 28.3 months (IQR: 13-74.1). Preoperative IIEF-5 was available in 55 patients with a median score of 14 (IQR: 3-20). The median IIEF-5 score at time of survey completion was 3 (IQR: 1-18). The majority of patients (55.1%) reported a perceived loss of penile length, 20.4% reported no loss, and 24.5% were unsure. Of those who quantified their loss in penile length, 54.6% reported losses of an inch or more. Neurovascular preservation was not found to protect against penile length loss but did correlate with a reduction in the amount reported lost (P = .008). Multivariable logistic regression analysis identified increasing IIEF-5 score at time of survey completion to protect against a perceived loss in penile length (odds ratio: 0.924, 95% confidence interval: 0.878-0.973, P = .0025), whereas increasing body mass index was associated with a loss in perceived penile length (odds ratio: 1.198, 95% confidence interval: 10.53-1.383, P = .0060). CLINICAL IMPLICATIONS: The perception of penile length loss is a commonly held belief in patients after RC, and many patients will perceive losses that exceed 1 inch (2.54 cm). STRENGTHS AND LIMITATIONS: This study is the first series to describe the perception of penile length loss after RC. It is strengthened by the study population's size, heterogeneity, and patient-reported results. It is limited by lack of objective measurements of stretched penile length. CONCLUSIONS: RC can result in significant sexual dysfunction including the perceived loss of penile length. Loh-Doyle JC, Han J, Ghodoussipour S.

RESUMO

PURPOSE: To perform an internal audit 5 years after implementation of our enhanced recovery after surgery (ERAS) protocol for patients undergoing radical cystectomy and to investigate the importance of physician driven compliance on outcomes. METHODS: Using a prospectively maintained database, 472 consecutive patients were identified who underwent radical cystectomy with ERAS from July 2013 to July 2017. Compliance was measured by a Composite Compliance Score (CCS) generated as a percentage of 16 interventions. Patients with higher than median compliance were compared to patients with lower compliance. The primary outcome was length of stay. Secondary outcomes included complication and readmission rates. Multivariable regressions were used to control for differences between groups. RESULTS: In 2013, median CCS was 81% and subsequently ranged from 81 to 88%. Five-year median CCS was 88%. Patients with higher compliance (CCS ≥ 88%, n = 262), as compared to those with lower compliance (CCS < 88%, n = 210), were younger (median 70.3 vs 72.7 years, p = 0.047), healthier (ASA3-4 81% vs 89.9%, p = 0.007), received more orthotopic diversions (59.2% vs 37.6%, p < 0.0001), more often had open surgery (78.5% vs 51.9%, p < 0.0001) and had shorter median operative times (5.5 vs 6.3 h, p = 0.005). Median length of stay was 4 days. Higher compliance was associated with shorter hospital stays (ß = - 0.85, 95% CI - 1.62 to - 0.07) and decreased 30-day readmissions (OR 0.58, 95% CI 0.35-0.96). CONCLUSIONS: Greater ERAS compliance was achieved in younger and healthier patients. Patients with greater compliance had a decreased length of stay by almost 1 day and reduced odds of 30-day readmissions.

RESUMO

PURPOSE: In this study, we investigate the effect of trainee involvement on surgical performance, as measured by automated performance metrics (APMs), and outcomes after robot-assisted radical prostatectomy (RARP). METHODS: We compared APMs (instrument tracking, EndoWrist® articulation, and system events data) and clinical outcomes for cases with varying resident involvement. Four of 12 standardized RARP steps were designated critical ("cardinal") steps. Comparison 1: cases where the attending surgeon performed all four cardinal steps (Group A) and cases where a trainee was involved in at least one cardinal step (Group B). Comparison 2, where Group A is split into Groups C and D: cases where attending performs the whole case (Group C) vs. cases where a trainee performed at least one non-cardinal step (Group D). Mann-Whitney U and Chi-squared tests were used for comparisons. RESULTS: Comparison 1 showed significant differences in APM profiles including camera movement time, third instrument usage, dominant instrument moving time, velocity, articulation, as well as non-dominant instrument moving time and articulation (all favoring Group A p < 0.05). There was a significant difference in re-admission rates (10.9% in Group A vs 0% in Group B, p < 0.02), but not for post-operative outcomes. Comparison 2 demonstrated a significant difference in dominant instrument articulation (p < 0.05) but not in post-operative outcomes. CONCLUSIONS: Trainee involvement in RARP is safe. The degree of trainee involvement does not significantly affect major clinical outcomes. APM profiles are less efficient when trainees perform at least one cardinal step but not during non-cardinal steps.

RESUMO

BACKGROUND: Presenting features of inflammatory bowel disease (IBD) are non-specific. We hypothesized that mRNA profiles could (1) identify genes and pathways involved in disease pathogenesis; (2) identify a molecular signature that differentiates IBD from other conditions; (3) provide insight into systemic and colon-specific dysregulation through study of the concordance of the gene expression. METHODS: Children (8-18 years) were prospectively recruited at the time of diagnostic colonoscopy for possible IBD. We used transcriptome-wide mRNA profiling to study gene expression in colon biopsies and paired whole blood samples. Using blood mRNA measurements, we fit a regression model for disease state prediction that was validated in an independent test set of adult subjects (GSE3365). RESULTS: Ninety-eight children were recruited [39 Crohn's disease, 18 ulcerative colitis, 2 IBDU, 39 non-IBD]. There were 1,118 significantly differentially (IBD vs non-IBD) expressed genes in colon tissue, and 880 in blood. The direction of relative change in expression was concordant for 106/112 genes differentially expressed in both tissue types. The regression model from the blood mRNA measurements distinguished IBD vs non-IBD disease status in the independent test set with 80% accuracy using only 6 genes. The overlap of 5 immune and metabolic pathways in the two tissue types was significant (p<0.001). CONCLUSIONS: Blood and colon tissue from patients with IBD share a common transcriptional profile dominated by immune and metabolic pathways. Our results suggest that peripheral blood expression levels of as few as 6 genes (IL7R, UBB, TXNIP, S100A8, ALAS2, and SLC2A3) may distinguish patients with IBD from non-IBD.

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 were 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 <.01), be upstaged (P <.01), have lymphovascular invasion (P <.01) and have lymph node metastasis at radical cystectomy (P = .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 = .003). At an 8-week delay or longer, those with variant histology had a statistically worse survival (P = .03). CONCLUSION: For patients with variant histology, delays in surgery were associated with an increased risk of death.

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

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

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: 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.
