OBJECTIVES: To quantitatively describe the nature, severity, and duration of symptoms and functional impairment during recovery from transurethral resection of bladder tumors. MATERIALS AND METHODS: All patients scheduled for transurethral resection were approached for enrollment in a text-message based ecological momentary symptom assessment platform. Nine patients reported outcomes were measured 7 days before surgery and on postoperative days 1, 2, 3, 5, 7, 10, and 14 using a 5-point Likert scale. Self-reported degree of hematuria was collected using a visual scale. Clinical data was collected via retrospective chart review. RESULTS: A total of 159 patients were analyzed. Postoperative symptoms were overall mild, with the largest differences from baseline to postoperative day 1 seen in dysuria (median 0/5 vs. 3/5) and ability to work (median 5/5 vs. 4/5). Recovery was generally rapid, with 76% of patients reporting ≥4/5 agreement with the statement "I feel recovered from surgery" by postoperative day 2, although 15% of patients reported persistently lower levels of agreement on postoperative day 10 or 14. Patients undergoing larger resections (≥2cm) did take longer to return to baseline in multiple symptom domains, but the difference of medians vs. those undergoing smaller resections was less than 1 day across all domains. Multivariable analysis suggested that receiving perioperative intravesical chemotherapy was associated with longer time to recovery. 84% of patients reported clear yellow urine by postoperative day 3. CONCLUSION: In this population, hematuria and negative effects on quality of life resulting from transurethral resection of bladder tumors were generally mild and short-lived, although a small number of patients experienced longer recoveries.

OBJECTIVE: To determine whether a simple point-of-care measurement system estimating renal parenchymal volume using tools ubiquitously available could be used to replace nuclear medicine renal scintigraphy (NMRS) in current clinical practice to predict estimated glomerular filtration rate (eGFR) after nephrectomy by estimating preoperative split renal function. PATIENTS AND METHODS: We performed a retrospective review of patients who underwent abdominal cross-sectional imaging (computed tomography/magnetic resonance imaging) and mercaptoacetyltriglycine (MAG3) NMRS prior to total nephrectomy at a single institution. We developed the real-time estimation of nephron activity with a linear measurement system (RENAL-MS) method of estimating postoperative renal function via the following technique: renal parenchymal volume of the removed kidney relative to the remaining kidney was estimated as the product of renal length and the average of six renal parenchymal thickness measurements. The utility of this value was compared to the utility of the split renal function measured by MAG3 for prediction of eGFR and new onset Stage 3 chronic kidney disease (CKD) at ≥90 days after nephrectomy using uni- and multivariate linear and logistic regression. RESULTS: A total of 57 patients met the study criteria. The median (interquartile range [IQR]) age was 69 (61-80) years. The median (IQR) pre- and postoperative eGFR was 74 (IQR 58-90) and 46 (35-62) mL/min/1.73 m2 , respectively. [Correction added on 29 December 2023, after first online publication: The data numbers in the preceding sentence have been corrected.] Correlations between actual and predicted postoperative eGFR were similar whether the RENAL-MS or NMRS methods were used, with correlation using RENAL-MS being slightly numerically but not statistically superior (R = 0.82 and 0.76; P = 0.138). Receiver operating characteristic curve analysis using logistic regression estimates incorporating age, sex, and preoperative creatinine to predict postoperative Stage 3 CKD were similar between RENAL-MS and NMRS (area under the curve 0.93 vs. 0.97). [Correction added on 29 December 2023, after first online publication: The data numbers in the preceding sentence have been corrected.] CONCLUSION: A point-of-care tool to estimate renal parenchymal volume (RENAL-MS) performed equally as well as NMRS to predict postoperative eGFR and de novo Stage 3 CKD after nephrectomy in our population, suggesting NMRS may not be necessary in this setting.

Accurate prediction of new baseline GFR (NBGFR) after radical nephrectomy (RN) can inform clinical management and patient counseling whenever RN is a strong consideration. Preoperative global GFR, split renal function (SRF), and renal functional compensation (RFC) are fundamentally important for the accurate prediction of NBGFR post-RN. While SRF has traditionally been obtained from nuclear renal scans (NRS), differential parenchymal volume analysis (PVA) via software analysis may be more accurate. A simplified approach to estimate parenchymal volumes and SRF based on length/width/height measurements (LWH) has also been proposed. We compare the accuracies of these three methods for determining SRF, and, by extension, predicting NBGFR after RN. All 235 renal cancer patients managed with RN (2006-2021) with available preoperative CT/MRI and NRS, and relevant functional data were analyzed. PVA was performed on CT/MRI using semi-automated software, and LWH measurements were obtained from CT/MRI images. RFC was presumed to be 25%, and thus: Predicted NBGFR = 1.25 × Global GFRPre-RN × SRFContralateral. Predictive accuracies were assessed by mean squared error (MSE) and correlation coefficients (r). The r values for the LWH/NRS/software-derived PVA approaches were 0.72/0.71/0.86, respectively (p < 0.05). The PVA-based approach also had the most favorable MSE, which were 120/126/65, respectively (p < 0.05). Our data show that software-derived PVA provides more accurate and precise SRF estimations and predictions of NBGFR post-RN than NRS/LWH methods. Furthermore, the LWH approach is equivalent to NRS, precluding the need for NRS in most patients.

OBJECTIVES: To validate the "overflowing beer sign" (OBS) for distinguishing between lipid-poor angiomyolipoma (AML) and renal cell carcinoma, and to determine whether it improves the detection of lipid-poor AML when added to the angular interface sign, a previously-validated morphologic feature associated with AML. METHODS: Retrospective nested case-control study of all 134 AMLs in an institutional renal mass database matched 1:2 with 268 malignant renal masses from the same database. Cross-sectional imaging from each mass was reviewed and the presence of each sign was identified. A random selection of 60 masses (30 AML and 30 benign) was used to measure interobserver agreement. RESULTS: Both signs were strongly associated with AML in the total population (OBS: OR 17.4 95% CI 8.0-42.5, p < 0.001; angular interface: OR 12.6, 95% CI 5.9-29.7, p < 0.001) and the population of patients excluding those with visible macroscopic fat (OBS: OR 11.2, 95% CI 4.8-28.7, p < 0.001; angular interface: 8.5, 95% CI 3.7-21.1, p < 0.001). In the lipid-poor population, the specificity of both signs was excellent (OBS: 95.6%, 95% CI 91.9%-98%; angular interface: 95.1%, 95% CI 91.3%-97.6%). Sensitivity was low for both signs (OBS: 31.4%, 95% CI 24.0-45.4%; angular interface: 30.5%, 95% CI 20.8%-41.6%). Both signs showed high levels of inter-rater agreement (OBS 90.0% 95% CI 80.5 - 95.9; angular interface 88.6, 95% CI 78.7-94.9) Testing for AML using the presence of either sign in this population improved sensitivity (39.0%, 95% CI 28.4%-50.4%, pâ¯=â¯0.023) without significantly reducing specificity (94.2%, 95% CI 90%-97%, pâ¯=â¯0.2) relative to the angular interface sign alone. CONCLUSIONS: Recognition of the OBS increases the sensitivity of detection of lipid-poor AML without significantly reducing specificity.

OBJECTIVES: To investigate the difference in renal function outcomes for patients with oncocytomas undergoing active surveillance (AS) vs. partial nephrectomy (PN). METHODS: We reviewed our institutional database for patients with biopsy/surgically confirmed oncocytoma from 2000-2020. The primary outcome was to assess for differences in renal function outcomes in patients undergoing AS vs. PN. We fit two generalized estimating equation (GEE) with an interaction term between follow up time and management strategy to predict 1) mean eGFR for patients managed with AS and PN and 2) the probability of progression to CKD stage III or greater. RESULTS: We identified 114 eligible patients, of which 32 were managed with AS. Median follow-up was 21 months vs. 44 months for PN vs. AS patients. AS patients tended to be older (median: 72 years vs. 65 years, P<0.001) and have lower baseline renal function (median: eGFR: 71 mL/min/1.73m2 vs. 82 mL/min/1.73m2, P<0.001) compared with PN patients. Renal mass size from baseline imaging was similar between patients undergoing PN vs. AS (2.8 cm vs. 2.9 cm, P=0.634). For patients undergoing PN vs. AS, there was not a significant difference in predicted longitudinal eGFR (-0.079, 95% CI -0.18-0.023, P=0.129) or predicted probability of progression to CKD stage III or greater (OR: 0.61, 95% CI: 0.16-2.33, P=0.47). CONCLUSIONS: In our institutional dataset, patients undergoing AS or PN with an oncocytoma had similar long-term renal function outcomes. Given similar renal function outcomes in patients undergoing AS and PN, surgery should remain reserved for select patients with oncocytomas.

INTRODUCTION: The presence of sarcomatoid features in localized renal cell carcinoma (RCC) is associated with worse outcomes. We sought to use a national database to evaluate the outcomes and prognosis of metastatic RCC (mRCC) with sarcomatoid features treated with cytoreductive nephrectomy (CN) and targeted therapy (TT). METHODS: The National Cancer Database (2010-2013) was used to identify patients with mRCC at diagnosis. Only patients who underwent CN followed by TT were included. Kaplan-Meier curves, log-rank test, and multivariate Cox regression analysis were used to compare overall survival (OS) between mRCC with and without sarcomatoid features. Subgroup analysis in patients with clear cell RCC (ccRCC) was performed. RESULTS: A total of 1,427 patients with mRCC treated with CN followed by TT were included of which 364 (26%) had mRCC with sarcomatoid features. mRCC with sarcomatoid features were more likely to have Fuhrman grade 4 cancer. mRCC with sarcomatoid features had worse OS than mRCC without sarcomatoid features (24.6 vs 12.0 months, P < 0.001). For the clear cell cohort, mRCC with sarcomatoid features had worse OS than mRCC without sarcomatoid features (26.2 vs 14.0 months, P < 0.001). Multivariate Cox regression showed sarcomatoid features was significantly associated with worse OS in the overall cohort (hazard ratio [HR] =1.63, 95% confidence interval [CI] =1.38-1.91, P < 0.001) and the ccRCC subcohort (HR=1.53, 95% CI=1.23-1.90, P < 0.001). DISCUSSION/CONCLUSION: mRCC with sarcomatoid features treated with CN and TT has a very poor and drastically different prognosis compared with mRCC without sarcomatoid features. With the expansion of systemic RCC therapies, investigation is needed to optimize treatment in this high-risk cohort.
RESUMO
PURPOSE: To elucidate which patients with clear cell renal cell carcinoma have the highest risk for disease relapse after curative nephrectomy is challenging but is acutely relevant in the era of approved adjuvant therapies. Pathological and genetic markers were used to improve the University of California Los Angeles Integrated Staging System (UISS) for the risk stratification and prognostication of recurrence free survival (RFS). PATIENTS AND METHODS: Necrosis, sarcomatoid features, Rhabdoid features, chromosomal loss 9p, combined chromosomal loss 3p14q and microvascular invasion (MVI) were tested in univariable and multivariable analyses for their ability to improve the discriminatory ability of the UISS. RESULTS: In the development cohort, during the median follow-up time of 43.4 months (±SD 54.1 months), 50/240 (21%) patients developed disease recurrence. MVI (HR: 2.22; p = 0.013) and the combined loss of chromosome 3p/14q (HR: 2.89; p = 0.004) demonstrated independent association with RFS and were used to improve the assignment to the UISS risk category. In the current UISS high-risk group, only 7/50 (14%) recurrence cases were correctly identified; while in the improved system, 23/50 (45%) were correctly prognosticated. The concordance index meaningfully improved from 0.55 to 0.68 to distinguish patients at intermediate risk versus high risk. Internal validation demonstrated a robust prognostication of RFS. In the external validation cohort, there was no case with disease recurrence in the low-risk group, and the mean RFS times were 13.2 (±1.8) and 8.2 (±0.8) years in the intermediate and high-risk groups, respectively. CONCLUSIONS: Adding MVI and combined chromosomal loss3p/14q to the UISS improves the ability to define the patient group with clear cell renal cell carcinomawho are at the highest risk for disease relapse after surgical treatment.

BACKGROUND: The diagnostic value of delayed nephrograms on contrast-enhanced computed tomography has not been studied rigorously. OBJECTIVE: To develop a method for quantitatively assessing delayed and diminished nephrograms (DDNs) easily at the point of care and to assess the association of DDNs with renal obstruction and renal function. DESIGN, SETTING, AND PARTICIPANTS: Data were reviewed from 76 patients who underwent a contrast-enhanced computed tomography scan within 30 days of a technetium-99m mercaptoacetyltriglycine diuretic renal scintigraphy (MAG3-DRS) which showed at least one kidney to have normal drainage (T1/2 <10 min) between 2010 and 2021 at a tertiary academic center. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Attenuations of the renal cortex and medulla were measured using circular regions of interest. These attenuations were compared between kidneys to compute several measures of DDN in the kidney with a greater concern for obstruction. Renal parenchymal volume and anterior-posterior renal pelvis diameter (APD) were estimated using simple linear measurements. Inter-rater reliability was computed using the intraclass correlation coefficient (ICC), correlations were computed using Spearman's R, and the relationships between DDN, APD, and renal function of the subject kidney were estimated using linear regression. RESULTS AND LIMITATIONS: Measures of DDN were highly reliable between raters (ICC 0.71-0.87). DDN was almost always associated with prolonged drainage on MAG3-DRS (90-100%); however, 33-52% of patients with prolonged drainage on MAG3-DRS had no appreciable DDN, depending on the measure of the DDN chosen. All measures of DDN were associated with decreased renal function (<0.001). APD did not significantly predict renal function when controlling for a DDN. CONCLUSIONS: DDNs on contrast-enhanced computed tomography are associated with renal obstruction and can easily and accurately be quantified at the point of care. A DDN is more closely associated with renal dysfunction than renal pelvic dilation and therefore may be useful in assessing the severity of upper tract obstruction. PATIENT SUMMARY: In this report, we confirm that a "delayed nephrogram", a classic x-ray finding thought to be associated with kidney blockage, is associated with blockage of the affected kidney. Furthermore, we show that a delayed nephrogram indicates that the affected kidney is not functioning as well as we would expect for a normal kidney of the same size. Since the severity of a delayed nephrogram predicts this decreased function better than the degree of dilation of the kidney, which is a different measurement often used to measure the severity of kidney blockage, the delayed nephrogram may be a better way of measuring the severity of kidney blockage in clinical practice.

BACKGROUND: Most safety and efficacy trials of the SARS-CoV-2 vaccines excluded patients with cancer, yet these patients are more likely than healthy individuals to contract SARS-CoV-2 and more likely to become seriously ill after infection. Our objective was to record short-term adverse reactions to the COVID-19 vaccine in patients with cancer, to compare the magnitude and duration of these reactions with those of patients without cancer, and to determine whether adverse reactions are related to active cancer therapy. PATIENTS AND METHODS: A prospective, single-institution observational study was performed at an NCI-designated Comprehensive Cancer Center. All study participants received 2 doses of the Pfizer BNT162b2 vaccine separated by approximately 3 weeks. A report of adverse reactions to dose 1 of the vaccine was completed upon return to the clinic for dose 2. Participants completed an identical survey either online or by telephone 2 weeks after the second vaccine dose. RESULTS: The cohort of 1,753 patients included 67.5% who had a history of cancer and 12.0% who were receiving active cancer treatment. Local pain at the injection site was the most frequently reported symptom for all respondents and did not distinguish patients with cancer from those without cancer after either dose 1 (39.3% vs 43.9%; P=.07) or dose 2 (42.5% vs 40.3%; P=.45). Among patients with cancer, those receiving active treatment were less likely to report pain at the injection site after dose 1 compared with those not receiving active treatment (30.0% vs 41.4%; P=.002). The onset and duration of adverse events was otherwise unrelated to active cancer treatment. CONCLUSIONS: When patients with cancer were compared with those without cancer, few differences in reported adverse events were noted. Active cancer treatment had little impact on adverse event profiles.

PURPOSE: Opioids are prescribed excessively following surgery. As many urologic oncology procedures are performed minimally invasively, an opportunity exists to push forward initiatives to minimize postoperative opioid use. MATERIALS AND METHODS: A quality improvement initiative to reduce inpatient opioid prescribing was launched at a tertiary cancer center. In Phase I (December 2019-July 2020), providers were instructed to start standing acetaminophen. In Phase II (beginning August 2020), education was provided to the entire care team and ordersets were modified to an opioid sparing protocol (OSP). We analyzed the proportion of minimally invasive surgery (MIS) prostatectomy and nephrectomy patients that adhered to an OSP during each phase and compared them to controls from the preceding 2 years. RESULTS: A total of 303, 153, and 839 patients underwent MIS during the Phase I, Phase II, and control periods respectively. The proportion of patients adhering to an OSP increased from 16% at the beginning of Phase I to 76% at the end of Phase II (p-trend < 0.001). The median total oral morphine equivalents for oral opioids declined from 20 mg and 40 mg at baseline for prostatectomy and nephrectomy patients respectively to 0 mg for both groups (p-trends < 0.001). Multivariable analysis found that patients received 22% and 81% less oral morphine equivalents during Phase I and II respectively compared to the control period (P < 0.001). CONCLUSIONS: Adherence to an OSP is most effective when initiatives incorporate the entire team and are supported by nudge theory-based structural changes. Using these strategies, most patients following urologic MIS can dramatically reduce opioid use postoperatively.

OBJECTIVES: To determine whether patients with carcinoma invading bladder muscle (MIBC) and ureteric obstruction can safely receive cisplatin-based neoadjuvant chemotherapy (C-NAC), and to determine whether such patients require relief of obstruction with a ureteric stent or percutaneous nephrostomy prior to beginning C-NAC. PATIENTS AND METHODS: We performed a single-institution retrospective analysis of MIBC patients receiving C-NAC and falling into three groups: no ureteric obstruction (NO); relieved ureteric obstruction (RO); and unrelieved ureteric obstruction (URO). To address whether patients with obstruction can safely receive C-NAC, we compared patients with NO to those with RO, with the primary outcome of premature chemotherapy discontinuation. To investigate whether patients with obstruction should have the obstruction relieved prior to NAC, we compared RO to URO patients using a primary composite outcome of grade ≥ 3 adverse events, premature chemotherapy discontinuation, dose reduction, or dose interruption. The primary outcomes were compared using multivariable logistic regression. Sensitivity analyses were performed for the RO vs URO comparison, in which patients with only mild degrees of obstruction were excluded from the URO group. RESULTS: A total of 193 patients with NO, 49 with RO, and 35 with URO were analysed. There were no statistically significant differences between those with NO and those with RO in chemotherapy discontinuation (15% vs 22%; P = 0.3) or any secondary outcome. There was no statistically significant difference between those with RO and URO in the primary composite outcome (51% vs 53%; P = 1) or any secondary outcome. CONCLUSION: Patients with ureteric obstruction can safely receive C-NAC. Relief of obstruction was not associated with increased safety of C-NAC delivery.

Radical cystectomy (RC) after neoadjuvant chemotherapy (NAC) is the gold standard for management of muscle-invasive bladder cancer (MIBC). Patients without residual tumor at the time of extirpative surgery (ypT0) have excellent prognosis. Distant metastases in this population are rare. We present a unique case of a patient with ypT0N0 urothelial carcinoma (UC) with rapid development of metastasis to the brain.
RESUMO
OBJECTIVE: To compare the feasibility and outcomes of renal mass biopsies (RMB) of anatomically complex vs non-complex renal masses. METHODS: Our institutional renal tumor database was queried for patients who underwent RMB between 2005 and 2019 and with available nephrometry score. Complex masses were: (1) small (<2 cm), (2) entirely endophytic (nephrometry E=3), (3) hilar (h) or (4) partially endophytic (E=2) and anterior. Demographic and pathologic data were compared. Biopsies were deemed adequate if they resulted in a diagnosis. Concordance with surgical pathology was assessed. These were both presented using proportions. Factors associated with biopsy outcomes were identified using multivariable logistic regression. RMB sensitivity and specificity were calculated using contingency methods. RESULTS: A total of 306 RBMs were included, 179 complex and 127 non-complex. A total of 199 (65%) had an extirpative procedure. Complex lesions were less likely to have an adequate biopsy (89% vs 96%, Pâ¯=â¯.03), and to be concordant with final surgical pathology from an oncologic standpoint (89% vs 97%, Pâ¯=â¯.03). There was no significant difference in concordance of histology (76% vs 86%, Pâ¯=â¯.10) or grade (48 vs 51%, Pâ¯=â¯.66). On multivariable analyses, only male gender was associated with biopsy adequacy (OR 3.31, 95% CI 1.28-8.55, Pâ¯=â¯.01). Our overall sensitivity was 93%, specificity 93%, and accuracy 93%. There were no significant differences over time in biopsy outcomes during the study period. CONCLUSION: RMB of complex lesions is associated with excellent diagnostic yield, albeit lower than non-complex lesions. RMB should not be deferred in cases of anatomically complex lesions where additional data could improve clinical decision-making.

OBJECTIVE: To test for an association between surgical delay and overall survival (OS) for patients with T2 renal masses. Many health care systems are balancing resources to manage the current COVID-19 pandemic, which may result in surgical delay for patients with large renal masses. METHODS: Using Cox proportional hazard models, we analyzed data from the National Cancer Database for patients undergoing extirpative surgery for clinical T2N0M0 renal masses between 2004 and 2015. Study outcomes were to assess for an association between surgical delay with OS and pathologic stage. RESULTS: We identified 11,848 patients who underwent extirpative surgery for clinical T2 renal masses. Compared with patients undergoing surgery within 2 months of diagnosis, we found worse OS for patients with a surgical delay of 3-4 months (hazard ratio [HR] 1.12, 95% confidence interval [CI] 1.00-1.25) or 5-6 months (HR 1.51, 95% CI 1.19-1.91). Considering only healthy patients with Charlson Comorbidity Index = 0, worse OS was associated with surgical delay of 5-6 months (HR 1.68, 95% CI 1.21-2.34, P= .002) but not 3-4 months (HR 1.08, 95% CI 0.93-1.26, P = 309). Pathologic stage (pT or pN) was not associated with surgical delay. CONCLUSION: Prolonged surgical delay (5-6 months) for patients with T2 renal tumors appears to have a negative impact on OS while shorter surgical delay (3-4 months) was not associated with worse OS in healthy patients. The data presented in this study may help patients and providers to weigh the risk of surgical delay versus the risk of iatrogenic SARS-CoV-2 exposure during resurgent waves of the COVID-19 pandemic.

OBJECTIVES: Financial incentive programs are effective in increasing physical activity for overweight, ambulatory adults. We sought to determine the potential effect size and direction of financial incentives on ambulation after radical cystectomy. MATERIALS AND METHODS: We performed a pilot randomized controlled trial of daily financial incentives to meet postoperative step goals among adults with Eastern Cooperative Oncology Group performance status ≤2 who underwent radical cystectomy for bladder cancer at a single center. Step counts were measured over a 3- to 14-day preoperative period and 30-day postoperative period using a wearable activity monitor. Postoperative daily step goals of 10%, 25%, 40%, and 55% of mean preoperative daily step counts were set for postoperative weeks 1 through 4, respectively. The primary outcome was the number of postoperative days on which the step goals were met. Secondary outcomes included the number of daily postoperative steps taken and the length of stay. Participants randomized to the intervention arm received $1.50 for every day the goal was met with a 20% chance of a $100 reward if the step goal was met on >75% of the first 30 postoperative days. Questionnaires assessing self-reported physical activity, disability, and social support were administered preoperatively at 30 days postoperatively. RESULTS: Thirty-three patients were analyzed, 11 in the control and 22 in the intervention arms. There were no statistically significant differences between incentive and control arms for the primary outcome (4.5/30 days vs. 9/30 days, Pâ¯=â¯0.53). Results after adjusting for differences in baseline characteristics were similar (RR 1.00, 95% CI 0.24-4.19, Pâ¯=â¯1.00). There were also no differences in average daily postoperative steps (median 979 vs. 1191, 95% CI -810 to 1,400, Pâ¯=â¯0.59), length of stay (7.5 vs. 7, 95% CI -2.7 to 5.1, Pâ¯=â¯0.56), or self-reported measures of disability, activity, and social support. CONCLUSIONS: While this trial was a pilot study and not powered to detect a difference between groups, there was no suggestion of any clinically important impact of this financial incentive on postoperative ambulation. While a fully-powered trial is feasible, given the small range of plausible benefit, such a trial would be unlikely to influence clinical practice.

BACKGROUND: Robot-assisted radical prostatectomy (RARP) can generally be performed with 1-2 nights of postoperative monitoring before discharge from the hospital. Little is known about what causes individual patients to remain in hospital beyond the second postoperative day. METHODS: Data for RARPs performed between 2013 and 2015 were extracted from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. The fraction of cases with prolonged length of stay (PLOS) that can be reasonably attributed to complications was examined. Logistic regression was performed to identify risk factors for PLOS in the overall population and separately in the population of patients with PLOS without any perioperative complications. RESULTS: Of 11,440 patients, 10,342 (90.4%) were discharged on postoperative days 0-2; 80.6% (887/1101) of patients with PLOS did not experience any perioperative complications. The most common complication was bleeding requiring transfusion, but this was present in only 5.6% (62/1101) of patients with PLOS. Logistic regression identified predictors of PLOS as age, race, wound class, American Society of Anesthesiologists class, smoking, diabetes, dyspnea, dependent functional health status, congestive heart failure, operative time, and pelvic lymph node dissection. Results of this regression were insensitive to the exclusion of patients who experienced no perioperative complications. CONCLUSIONS: This study utilizes logistic regression on NSQIP data to identify risk factors for PLOS after RARP and, in particular, to evaluate the role of postoperative complications in PLOS. The analysis shows that postoperative complications account for a small minority of cases of PLOS after RARP.
