ABSTRACT
INTRODUCTION: This study aimed to assess patient compliance with a newly established electronic patient-reported outcome measure (ePROM) system after urologic surgery and to identify influencing factors. METHODS: Digital surveys were provided to patients undergoing cystectomy, radical or partial nephrectomy, or transurethral resection of bladder tumor via a newly established ePROM system. Participants received a baseline survey preoperatively and several follow-up surveys postoperatively. Multivariable regression analysis was performed to identify factors predicting compliance. RESULTS: Of N = 435 eligible patients, n = 338 completed the baseline survey (78.0%). Patients who did not participate were significantly more likely male (p = 0.004) and older than 70 years (p = 0.005). Overall, 206/337 patients (61.3%) completed the survey at 1-month, 167/312 (53.5%) at 3-month, and 142/276 (51.4%) at 6-month follow-up. Lower baseline quality of life (odds ratio: 2.27; p = 0.004) was a significant predictor for dropout at 1-month follow-up. Low educational level was significantly associated with low compliance at 3- (OR: 1.92; p = 0.01) and 6-month follow-up (OR: 2.88; p < 0.001). CONCLUSION: Acceptable compliance rates can be achieved with ePROMs following urologic surgery. Several factors influence compliance and should be considered when setting-up ePROM surveys.

Radiomics may increase the diagnostic accuracy of medical imaging for localized and metastatic RCC (mRCC). A systematic review and meta-analysis was performed. Doing so, we comprehensively searched literature databases until May 2020. Studies investigating the diagnostic value of radiomics in differentiation of localized renal tumors and assessment of treatment response to ST in mRCC were included and assessed with respect to their quality using the radiomics quality score (RQS). A total of 113 out of 1098 identified studies met the criteria and were included in qualitative synthesis. Median RQS of all studies was 13.9% (5.0 points, IQR 0.25-7.0 points), and RQS increased over time. Thirty studies were included into the quantitative synthesis: For distinguishing angiomyolipoma, oncocytoma or unspecified benign tumors from RCC, the random effects model showed a log odds ratio (OR) of 2.89 (95%-CI 2.40-3.39, p < 0.001), 3.08 (95%-CI 2.09-4.06, p < 0.001) and 3.57 (95%-CI 2.69-4.45, p < 0.001), respectively. For the general discrimination of benign tumors from RCC log OR was 3.17 (95%-CI 2.73-3.62, p < 0.001). Inhomogeneity of the available studies assessing treatment response in mRCC prevented any meaningful meta-analysis. The application of radiomics seems promising for discrimination of renal tumor dignity. Shared data and open science may assist in improving reproducibility of future studies.
ABSTRACT
OBJECTIVES: To compare the operative and functional result of partial and radical nephrectomy in renal cell carcinomas of stages pT2-3a. METHODS: Consecutive patients with renal cell carcinoma of stages pT2-3a, cN0 and cM0, who underwent partial or radical nephrectomy between January 2005 and October 2019 at a tertiary care center were included. Data were collected retrospectively. End-points included severe postoperative complications (Clavien-Dindo classification ≥3), acute and chronic renal function impairment, and overall survival. Uni- and multivariable outcome analyses were based on logistic regression. RESULTS: A total of 158 patients were included (110 radical nephrectomy and 48 partial nephrectomy). Over time, partial nephrectomy was increasingly used. A RENAL score ≥10 was the only independent predictor influencing the surgical approach (radical nephrectomy vs partial nephrectomy, odds ratio 8.62, 95% confidence interval 3.32-22.37, P < 0.001). No significant differences in complications for radical nephrectomy versus partial nephrectomy were found (12.7% vs 8.3%, P = 0.424). Renal function was better preserved in the partial nephrectomy group (the latest chronic kidney disease stage ≥3: radical nephrectomy 73% vs partial nephrectomy 41%, P = 0.005). The surgical approach was a significant factor for chronic kidney disease (odds ratio 51.07, 95% confidence interval 3.57-730.59, P = 0.004). Overall survival did not significantly differ between radical nephrectomy and partial nephrectomy (mean overall survival 85.86 months, 95% confidence interval 3.83-78.36 vs 81.28 months, 95% confidence interval 4.59-72.29, P = 0.702). CONCLUSIONS: In selected patients, partial nephrectomy can be used in large or locally advanced renal cell carcinoma. Compared with radical nephrectomy, it allows better preservation of renal function without harboring an increased risk of severe postoperative complications.
