RESUMEN

PURPOSE: We examine the timing, patterns and predictors of 90-day readmission after robotic radical cystectomy. MATERIALS AND METHODS: From September 2009 to March 2017, 271 consecutive patients undergoing robotic radical cystectomy with intent to cure bladder cancer (intracorporeal diversion 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 or more readmissions within a 90-day period. Logistic regression analysis was used to identify independent factors related to single and multiple 90-day readmissions. RESULTS: A total of 78 (28.8%) patients were readmitted at least once within 90 days after discharge, of whom 20 (25.6%) reported multiple readmissions. The cumulative duration of readmission was 6.2 (6.17) days with 6 (7.6%) patients having less than 24 hours readmission. Metabolic, infectious, genitourinary and gastrointestinal complications were identified as the primary cause of readmission in 39.5%, 23.5%, 22.3% and 17%, respectively. Fifty percent of readmissions occurred in the first 2 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. CONCLUSIONS: 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 derangements and infections being the most common causes.

RESUMEN

OBJECTIVES: To evaluate the impact of 5-alpha reductase inhibitors (5-ARIs) on definitive treatment (DT) and pathological progression (PP) in patients on active surveillance (AS) for prostate cancer. METHODS: We identified 361 consecutive patients, from an IRB-approved database, on AS for prostate cancer with minimum 2 years follow-up. Patients were grouped into two cohorts, those using 5-ARIs (5-ARI; n = 119) or not using 5-ARIs (no 5-ARI; n = 242). Primary and secondary endpoints were treatment-free survival (TFS) and PP-free survival (PPFS), which were evaluated by Kaplan-Meier analysis. Univariate and multivariable cox regression analysis were used to identify predictors for PP and DT. A p value < 0.05 was considered statistically significant. RESULTS: Baseline characteristics and the prostate biopsy rate were similar between the two groups. Median (range) follow-up was 5.7 (2.0-17.2) years. Five-year and 10-year TFS was 92% and 59% for the 5-ARI group versus 80% and 51% for the no 5-ARI group (p = 0.005), respectively. Five-year and 10-year PPFS was 77% and 41% for the 5-ARI group versus 70% and 32% for the no 5-ARI group (p = 0.04), respectively. Independent predictors for treatment and PP were not taking 5-ARIs (p = 0.005; p = 0.02), entry PSA > 2.5 ng/mL (p = 0.03; p = 0.01) and Gleason pattern 4 on initial biopsy (p < 0.001; p < 0.001), respectively. The main limitation is the retrospective study design. CONCLUSIONS: 5-ARIs reduces reclassification and cross-over to treatment in men on active surveillance for prostate cancer. Further, taking 5-ARIs was an independent predictor for prostate cancer progression and definitive treatment.

RESUMEN

PURPOSE: To assess the feasibility, safety, and outcomes of an expedited One-Stop prostate cancer (PCa) diagnostic pathway. PATIENTS AND METHODS: We identified 370 consecutive patients who underwent multiparametric magnetic resonance imaging (mpMRI) and transrectal ultrasound fusion prostate biopsy (MRI/TRUS-PBx) from our institutional review board-approved database. Patients were divided according to diagnostic pathway: One-Stop (n = 74), with mpMRI and same-day PBx, or Standard (n = 296), with mpMRI followed by a second visit for PBx. mpMRIs were performed and interpreted according to Prostate Imaging-Reporting and Data System (PI-RADS v2). Grade group ≥ 2 PCa defined clinically significant PCa (csPCa). Statistical significance was considered when p < 0.05. RESULTS: Age (66 vs 66 years, p = 0.59) and PSA density (0.1 vs 0.1 ng/mL2, p = 0.26) were not different between One-Stop vs Standard pathway, respectively. One-Stop patients lived further away from the hospital than Standard patients (163 vs 31 km; p < 0.01), and experienced shorter time from mpMRI to PBx (0 vs 7 days; p < 0.01). The number (p = 0.56) and distribution of PI-RADS lesions (p = 0.67) were not different between the groups. All procedures were completed successfully with similar perioperative complications rate (p = 0.24). For patients with PI-RADS 3-5 lesions, the csPCa detection rate (49% vs 41%, p = 0.55) was similar for One-Stop vs Standard, respectively. The negative predictive value of mpMRI (PI-RADS 1-2) for csPCa was 78% for One-Stop vs 83% for Standard (p = 0.99). On multivariate analysis, age, prostate volume and PI-RADS score (p < 0.01), but not diagnostic pathway, predicted csPCa detection. CONCLUSION: A One-Stop PCa diagnostic pathway is feasible, safe, and provides similar outcomes in a shorter time compared to the Standard two-visit diagnostic pathway.

RESUMEN

High-risk prostate cancer (PCa) is associated with higher rates of biochemical recurrence, clinical recurrence, metastasis, and PCa-specific death, compared to low-and intermediate-risk disease. Herein, we review the various definitions of high-risk PCa, describe the rationale for neoadjuvant therapy prior to radical prostatectomy, and summarize the contemporary data on neoadjuvant therapies. Since the 1990s, several randomized trials of neoadjuvant androgen deprivation therapy (ADT) have consistently demonstrated improved pathological parameters, specifically tumor downstaging and reduced extraprostatic extension, seminal vesicle invasion, and positive surgical margins without improvements in cancer-specific or overall survival. These studies, however, were not exclusive to high-risk patients and were limited by suboptimal follow-up periods. Newer studies of neoadjuvant ADT in high-risk PCa show promising pathological and oncological outcomes. Recent level 1 data suggests neoadjuvant chemohormonal therapy (CHT) may improve longer-term survival in high-risk PCa. Immunologic neoadjuvant trials are in their infancy, and further study is required. Neoadjuvant therapies may be promising additions to the multimodal therapeutic landscape of high-risk and locally advanced PCa in the near future.

RESUMEN

PURPOSE: We sought to determine whether there is a subset of men who can avoid prostate biopsy based on multiparametric magnetic resonance imaging and clinical characteristics. MATERIALS AND METHODS: Of 1,149 consecutive men who underwent prostate biopsy from October 2011 to March 2017, 135 had prebiopsy negative multiparametric magnetic resonance imaging with PI-RADS™ (Prostate Imaging Reporting and Data System) score less than 3. The detection rate of clinically significant prostate cancer was evaluated according to prostate specific antigen density and prior biopsy history. Clinically significant prostate cancer was defined as Grade Group 2 or greater. Multivariable logistic regression analysis was performed to identify predictors of nonclinically significant prostate cancer on biopsy. RESULTS: The prostate cancer and clinically significant prostate cancer detection rates were 38% and 18%, respectively. Men with biopsy detected, clinically significant prostate cancer had a smaller prostate (p = 0.004), higher prostate specific antigen density (p = 0.02) and no history of prior negative biopsy (p = 0.01) compared to the nonclinically significant prostate cancer cohort. Prostate specific antigen density less than 0.15 ng/ml/cc (p <0.001) and prior negative biopsy (p = 0.005) were independent predictors of absent clinically significant prostate cancer on biopsy. The negative predictive value of multiparametric magnetic resonance imaging for biopsy detection of clinically significant prostate cancer improved with decreasing prostate specific antigen density, primarily in men with prior negative biopsy (p = 0.001) but not in biopsy naïve men. Of the men 32% had the combination of negative multiparametric magnetic resonance imaging, prostate specific antigen density less than 0.15 ng/ml/cc and negative prior biopsy, and none had clinically significant prostate cancer on repeat biopsy. The incidence of biopsy identified, clinically significant prostate cancer was 18%, 10% and 0% in men with negative multiparametric magnetic resonance imaging only, men with negative multiparametric magnetic resonance imaging and prostate specific antigen density less than 0.15 ng/ml/cc, and men with negative multiparametric magnetic resonance imaging, prostate specific antigen density less than 0.15 ng/ml/cc and negative prior biopsy, respectively. CONCLUSIONS: We propose that a subset of men with negative multiparametric magnetic resonance imaging, prostate specific antigen density less than 0.15 ng/ml/cc and prior negative biopsy may safely avoid rebiopsy. Conversely prostate biopsy should be considered in biopsy naïve men regardless of negative multiparametric magnetic resonance imaging, particularly those with prostate specific antigen density greater than 0.15 ng/ml/cc.

RESUMEN

OBJECTIVE: To evaluate the impact of indocyanine green (ICG) for assessing ureteric vascularity on the rate of uretero-enteric stricture formation after robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD). PATIENTS AND METHODS: We identified 179 patients undergoing RARC and ICUD between January 2014 and May 2017, and divided the patients into two groups based on the utilisation of ICG for the assessment of ureteric vascularity (non-ICG group and ICG group). We retrospectively reviewed the medical records to identify the length of ureter excised. Demographic, perioperative outcomes (including 90-day complications and readmissions), and the rate of uretero-enteric stricture were compared between the two groups. The two groups were compared using the t-test for continuous variables and the chi-squared test for categorical variables. A P < 0.05 was considered statistically significant. RESULTS: A total of 132 and 47 patients were in the non-ICG group and the ICG group, respectively. There were no differences in baseline characteristics and perioperative outcomes including operating time, estimated blood loss, and length of stay. The ICG group was associated with a greater length of ureter being excised during the uretero-enteric anastomosis and a greater proportion of patients having long segment (>5 cm) ureteric resection. The median follow-up was 14 and 12 months in the non-ICG and ICG groups, respectively. The ICG group was associated with no uretero-enteric strictures compared to a per-patient stricture rate of 10.6% and a per-ureter stricture rate of 6.6% in the non-ICG group (P = 0.020 and P = 0.013, respectively). CONCLUSION: The use of ICG fluorescence to assess distal ureteric vascularity during RARC and ICUD may reduce the risk of ischaemic uretero-enteric strictures. The technique is simple, safe, and reproducible. Larger studies with longer follow-up are needed to confirm our findings.

RESUMEN

The optimal strategy for imaging after focal therapy for prostate cancer is evolving. This series is an initial report on the use of contrast-enhanced transrectal ultrasound (TRUS) in follow-up of patients after high-intensity focused ultrasound (HIFU) hemiablation for prostate cancer. In 7 patients who underwent HIFU hemiablation, contrast-enhanced TRUS findings were as follows: (1) contrast-enhanced TRUS clearly showed the HIFU ablation defect as a sharply marginated nonenhancing zone in all patients; (2) contrast-enhanced TRUS identified suspicious foci of recurrent enhancement within the ablation zone in 2 patients, facilitating image-guided prostate biopsy, which showed prostate cancer; and (3) contrast-enhanced TRUS findings correlated with multiparametric magnetic resonance imaging and biopsy histologic findings.

RESUMEN

OBJECTIVE: To report procedure process improvements and confirm the preserved safety and short-term effectiveness of a second-generation Aquablation device for the treatment of lower urinary tract symptoms (LUTS) attributable to benign prostatic hyperplasia (BPH) in 47 consecutive patients at a single institution. PATIENTS AND METHODS: Aquablation was performed in 47 patients with symptomatic BPH at a single institution. Baseline, peri-operative and 3-month urinary function data were collected. RESULTS: The mean (range) patient age was 66 (50-79) years, and transrectal ultrasonography-measured prostate volume was 48 (20-118) mL. A median lobe was present in 25 patients (53%) and eight patients had catheter-dependent urinary retention. The mean (range) total procedure time was 35 (13-128) min and the tissue resection time was 4 (1-10) min. Five Clavien-Dindo grade I/II and five Clavien-Dindo grade III complications were recorded in eight patients. The mean (range) hospital stay was 3.1 (1-8) days and the mean (range) duration of urethral catheterization was 1.9 (1-11) days. The mean International Prostate Symptom Score (IPSS) decreased from 24.4 at baseline to 5 at 3 months; IPSS quality-of-life score decreased from 4.5 to 0.3 points; peak urinary flow rate increased from 7.1 to 16.5 mL/s and post-void residual urine volume decreased from 119 to 43 mL (all P < 0.01). CONCLUSIONS: This study confirmed procedure process improvements resulting from system enhancements, with preservation of safety and effectiveness during use of a second-generation device for the treatment of LUTS attibutable to BPH in the largest single-institution study conducted to date.

RESUMEN

PURPOSE OF REVIEW: To present a perspective on the current status and future directions of focal therapy for prostate cancer (PCa). RECENT FINDINGS: Focal therapy for localized PCa is a rapidly evolving field. Various recent concepts - the index lesion driving prognosis, the enhanced detection of clinically significant PCa using multiparametric MRI and targeted biopsy, improved risk-stratification using novel blood/tissue biomarkers, the recognition that reducing radical treatment-related morbidity (along with reducing pathologic progression) is a clinically meaningful end-point - have all led to a growing interest in focal therapy. Novel focal therapy modalities are being investigated, mostly in phase 1 and 2 studies. Recently, level I prospective randomized data comparing partial gland ablation with a standard-of-care treatment became available from one study. Recent developments in imaging, including 7-T MRI, functional imaging, radiomics and contrast-enhanced ultrasound show early promise. We also discuss emerging concepts in patient selection for focal therapy. SUMMARY: PCa focal therapy has evolved considerably in the recent few years. Overall, these novel focal therapy treatments demonstrate safety and feasibility, low treatment-related toxicity and acceptable short-term and in some cases medium-term oncologic outcomes. As imaging techniques evolve, patient selection, detection of clinically significant PCa and noninvasive assessment of therapeutic efficacy will be further optimized. The aspirational goal of achieving oncologic control while reducing radical treatment-related morbidity will drive further innovation in the field.

RESUMEN

PURPOSE OF REVIEW: Contrast-enhanced transrectal ultrasound (CeTRUS) is an emerging imaging technique in prostate cancer (PCa) diagnosis and treatment. We review the utility and implications of CeTRUS in PCa focal therapy (FT). RECENT FINDINGS: CeTRUS utilizes intravenous injection of ultrasound-enhancing agents followed by high-resolution ultrasound to evaluate tissue microvasculature and differentiate between benign tissue and PCa, with the latter demonstrating increased enhancement. The potential utility of CeTRUS in FT for PCa extends to pre-, intra- and post-operative settings. CeTRUS may detect PCa, facilitate targeted biopsy and aid surgical planning prior to FT. During FT, the treated area can be visualized as a well-demarcated non-enhancing zone and continuous real-time assessment allows immediate re-treatment if necessary. Following FT, the changes on CeTRUS are immediate and consistent, thus facilitating repeat imaging for comparison during follow-up. Areas suspicious for recurrence may be detected and target-biopsied. Enhancement can be quantified using time-intensity curves allowing objective assessment and comparison. Based on encouraging early outcomes, CeTRUS may become an alternative imaging modality in prostate cancer FT. Further study with larger cohorts and longer follow-up are needed.

RESUMEN

The purpose of the study is to evaluate the impact of a multimodal Enhanced Recovery After Surgery (ERAS) protocol on perioperative opioid consumption and hospital length of stay (LOS) after robotic-assisted radical prostatectomy (RARP). We compared the first 176 patients enrolled in the protocol (ERAS group) with the previous 176 patients (non-ERAS group) at a single quaternary institution from December 2017 to June 2019. The ERAS protocol included a multimodal opioid-sparing regimen utilizing acetaminophen, gabapentin, celecoxib, and liposomal bupivacaine. Demographic data, co-morbidities, post-operative pain scores, post-operative opiate consumption measured by morphine milligram equivalents (MME), operating time, and LOS were collected. The two groups were compared using chi-squared, Fisher exact, or Student t tests as appropriate. Multivariable logistic regression analysis was performed to identify predictors of prolonged LOS (> 1 day). The ERAS and non-ERAS groups were equivalent in terms of baseline characteristics and pathological data. The ERAS group had lower post-operative pain scores, post-operative opiate consumption (MME 15 vs. 46, p < 0.01), and LOS (1.2 vs. 1.7 days, p < 0.01) compared to the non-ERAS group. Only 22% in the ERAS cohort had a prolonged LOS compared to 39% of the non-ERAS group (p < 0.01). The ERAS protocol was a negative predictor of prolonged LOS on multivariable logistic regression analysis (odds ratio 0.39, 95% confidence interval 0.22-0.70, p < 0.01). A limitation of this study is its single-center retrospective design. The implementation of a multimodal opioid-sparing ERAS protocol was associated with improved pain control, reduced perioperative opioid usage, and shorter LOS after RARP.

RESUMEN

Enhanced Recovery After Surgery (ERAS) protocols have been developed in several fields to reduce hospitalization lengths and overall costs. There have also been developments in multimodal analgesia methods to curtail opioid usage after surgery. Herein, we present the results of our initiation of an ERAS protocol for robotic-assisted laparoscopic partial and radical nephrectomies, employing a quadratus lumborum (QL) regional anesthetic block. We retrospectively reviewed 614 patients in our Institutional Review Board approved database who underwent robotic-assisted laparoscopic partial or radical nephrectomies from January 2017 to February 2020. An ERAS protocol utilizing multimodal analgesia (acetaminophen and gabapentin) and a QL block was developed and introduced in February 2019. We then compared the opioid consumption and perioperative outcomes of patients before and after ERAS protocol initiation. 192 ERAS patients (February 2019 to February 2020) were compared to 422 non-ERAS patients (January 2017 to January 2019). Baseline characteristics and the proportion of preoperative opioids users were similar between the two groups. There were no statistically significant differences in surgery length, hospitalization length, or complication rates. There were statistically significant differences in our primary endpoint, opioid consumption, on post-operative days 0 (p < 0.001), 1 (p < 0.001), and 2 (p < 0.001). The total opioid requirements over the course of admission were lower in the ERAS group compared to the non-ERAS group (p = 0.03). The initiation of an ERAS protocol employing multimodal analgesia and a QL block, for patients undergoing robotic-assisted laparoscopic partial or radical nephrectomies, can decrease opioid requirements without compromising perioperative outcomes.

RESUMEN

INTRODUCTION: Tri-tubular penile fracture is a very rare subset of penile fractures, typically due to high-energy trauma to the erect penis. CASE PRESENTATION: A 26-year-old healthy man presents with a triad of audible crack, immediate detumescence, and hematoma formation, following blunt trauma sustained during vaginal sexual intercourse. A diagnosis of penile fracture is made, with intraoperative finding of a complete traumatic transection of the urethra with total bilateral corpus cavernosa disruption. Both corpora cavernosa were repaired using 2/0 polydioxanone sutures, with the dartos fascia placed in between. The urethra was repaired with interrupted 5/0 polyglactin braided absorbable suture. At 5 weeks, patient reported normal erections and sexual activity with no physical or psychological issues. The literature on management was reviewed. CONCLUSION: Current evidence of surgical management of tri-tubular penile fractures remains predominantly expert opinion, due to difficulties of conducting prospective trials for a rare condition.

RESUMEN

BACKGROUND: Use of partial nephrectomy (PN) in T3 renal cell carcinoma (RCC) is controversial. OBJECTIVE: To evaluate quality outcomes of robot-assisted PN (RAPN) for clinical T3a renal masses (cT3aRM). DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective multicenter analysis of patients with cT3aN0M0 RCC who underwent RAPN. INTERVENTION: RAPN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was a trifecta composite outcome of negative surgical margins, warm ischemia time (WIT) ≤25 min, and no perioperative complications. The optimal outcome was defined as achieving this trifecta and ≥90% preservation of the estimated glomerular filtration rate (eGFR) and no stage upgrading of chronic kidney disease. Multivariable analysis (MVA) identified risk factors associated with lack of the optimal outcome. Kaplan-Meier analysis was conducted for survival outcomes. RESULTS AND LIMITATIONS: Analysis was conducted for 157 patients (median follow-up 26 mo). The median tumor size was 7.0 cm (interquartile range [IQR] 5.0-7.8) and the median RENAL score was 9 (IQR 8-10). Median estimated blood loss (EBL) was 242 ml (IQR 121-354) and the median WIT was 19 min (IQR 15-25). A total of 150 patients (95.5%) had negative margins. Complications were noted in 25 patients (15.9%), with 4.5% having Clavien grade 3-5 complications. The median change in eGFR was 7 ml/min/1.72 m2, with ≥90% eGFR preservation in 55.4%. The trifecta outcome was achieved for 64.3% and the optimal outcome for 37.6% of the patients. MVA revealed that greater age (odds ratio [OR] 1.06; p = 0.002), increasing RENAL score (OR 1.30; p = 0.035), and EBL >300 ml (OR 5.96, p = 0.006) were predictive of failure to achieve optimal outcome. The 5-yr recurrence-free survival, cancer-specific survival, and overall survival, were 82.1%, 93.3%, and 91.3%, respectively. Limitations include the retrospective design. CONCLUSIONS: RAPN for select cT3a renal masses is feasible and safe, with acceptable quality outcomes. Further investigation is requisite to delineate the role of RAPN in cT3a RCC. PATIENT SUMMARY: Robot-assisted partial nephrectomy in patients with stage 3a kidney cancer provided acceptable survival, functional, and morbidity outcomes in the hands of experienced surgeons, and may be considered as an option when clinically indicated.

RESUMEN

Minimally invasive renal surgery has revolutionized the surgical management of renal cancer since the initial report of laparoscopic nephrectomy in 1991. Laparoscopic nephrectomy became the mainstay of management in surgically resectable renal masses since the 1990s. The growing body of literature supporting nephron-sparing surgery over the last two decades has meant that minimally invasive radical nephrectomy (MI-RN) is now the preferred treatment for renal tumors not amenable to partial nephrectomy. While there is a well-described experience with complex radical nephrectomy using standard laparoscopy, robot-assisted surgery has shortened the learning curve and facilitated greater uptake of minimally invasive surgery in difficult surgical scenarios traditionally performed open surgically. Increased experience and expertise with robot-assisted renal surgery has led to expansion of the indications for MI-RN to include larger masses, locally advanced renal masses invading adjacent tissues or regional hilar/retroperitoneal lymph nodes, cytoreductive nephrectomy (CN) in metastatic disease, and concurrent venous tumor thrombectomy for renal vein or inferior vena cava (IVC) involvement. In this article, we review the various surgical techniques and adjunctive procedures associated with MI-RN.

RESUMEN

A 41-year-old man presented with a 5-month history of bothersome urinary urgency and frequency. He sustained a gunshot wound to the lower abdomen 15 months prior to presentation. Digital rectal examination revealed a metallic foreign body palpable within the right lobe of the prostate, which was suggestive of a retained bullet fragment within the prostate gland. Cystourethroscopy confirmed a bullet fragment lodged within the right lateral aspect of the prostatic urethra. X-ray of the pelvis illustrated 2 radiopaque foreign bodies projecting at the level of the pubis. The patient deferred surgical retrieval and opted for pharmacological management with anti-cholinergic medication.

RESUMEN

A 77 year-old man was referred to Urology with an enlarging left adrenal mass after treatment with androgen deprivation therapy for metastatic castrate-resistant prostate cancer. He underwent a robotic-assisted left radical adrenalectomy, with pathology revealing metastatic adenocarcinoma consistent with a primary prostate adenocarcinoma. The patient had a durable oncological response to metastasectomy with no evidence of biochemical or radiological recurrence after 5 years of follow-up. Adrenal metastases from prostate cancer are extremely rare, representing only 1% of metastatic cases. Surgical resection of oligometastatic prostate cancer recurrences may be considered in select patients and may improve progression-free survival.

RESUMEN

OBJECTIVES: Surgically treated clinical T1 (cT1) kidney cancer has in general a good prognosis, but there is a risk of upstaging that can potentially jeopardize the oncological outcomes after partial nephrectomy (PN). Aim of this study is to analyze the outcomes of robot-assisted PN (RAPN) for cT1 kidney cancer upstaged to pT3a, and to identify predictors of upstaging. MATERIAL AND METHODS: The study cohort included 1,640 cT1 patients who underwent RAPN between 2005 and 2018 at 10 academic institutions. Multivariate logistic regression model was used to assess the predictors of upstaging. Kaplan-Meier curves and multivariable Cox regression analyses were used to evaluate recurrence-free survival and overall survival. RESULTS: Overall, 74 (4%) were upstaged cases (cT1/pT3a). Upstaged patients presented larger renal tumors (3.1 vs. 2.4 cm; P = 0.001), and higher R.E.N.A.L. score (8.0 vs. 6.0; P = 0.004). cT1/pT3a group had higher rate of intraoperative complications (5 vs. 1% P = 0.032), higher pathological tumor size (3.2 vs. 2.5 cm; P < 0.001), higher rate of Fuhrman grade ≥3 (32 vs. 17%; P = 0.002), and higher number of sarcomatoid differentiation (4 vs. 1%; P = 0.008). Chronic kidney disease (CKD) stage ≥3 (OR: 2.54; P < 0.014), and clinical tumor size (OR: 1.07; P < 0.001) were independent predictors of upstaging. cT1/pT3a group had worse 2-year (94% vs. 99%) recurrence-free survival (P < 0.001). CONCLUSIONS: Upstaging to pT3a in patients with cT1 renal mass undergoing RAPN represents an uncommon event, involving less than 5% of cases. Pathologic upstaging might translate into worse oncological outcomes, and therefore strict follow-up protocols should be applied in these cases.

RESUMEN

OBJECTIVES: We assessed recent trends in both urinary diversion after radical cystectomy for bladder cancer in the United States and patient- and hospital-related characteristics. We also identified variables associated with undergoing continent diversion. MATERIALS AND METHODS: We queried the National Cancer Database and identified 27,170 patients who underwent radical cystectomy with urinary diversion from 2004 to 2013. Patient demographics, socioeconomic variables, and hospital-related factors were compared between incontinent and continent diversion and trended over time. Multivariable logistic regression was used to identify variables associated with undergoing continent diversion. RESULTS: Overall, 23,224 (85.5%) and 3,946 (14.5%) patients underwent incontinent and continent diversion, respectively. Continent diversion declined from 17.2% in 2004 to 2006 to 12.1% in 2010 to 2013 (P < 0.01). When analyzing high-volume facilities, those performing ≥75% minimally invasive radical cystectomy had fewer continent diversions (10.2%) compared to centers with higher rate of open approach (19.7%), P < 0.01. Higher income, facility located in the West, academic programs, high-volume facilities, and patients traveling >60 miles for care were significantly associated with undergoing continent diversion. Rate of continent diversion has declined in most patient- and hospital-related subgroups. Compared to 2004 to 2006, patients in 2010 to 2013 were more likely to be older, have more comorbidities, and be operated on at a high-volume academic facility. CONCLUSION: The rate of continent diversion has declined to 12.1% in the United States. Hospital volume and type, patient income, distance traveled for care, and geography are significantly associated with undergoing continent diversion. Even among high-volume and academic centers, the rate of continent diversion is declining.
