Purpose: Radical cystectomy (RC), which is the standard of care for muscle-invasive and high-grade noninvasive bladder cancer, is accompanied by postoperative renal function deterioration. We aimed to evaluate the effect of serum albumin level on postoperative renal function decline after RC. Materials and Methods: A total of 272 patients with estimated glomerular filtration rate (eGFR) ≥60 mL/minute/1.73 m 2 who underwent RC between October 2003 and December 2020 were included. Acute kidney injury (AKI) was defined according to the KDIGO (Kidney Disease Improving Global Outcomes) criteria, while postoperative chronic kidney disease (CKD) progression was defined as an eGFR <60 mL/minute/1.73 m 2 at ≥3 months after RC. Results: In our cohort, 20 (7.4%) and 99 (36.4%) patients experienced postoperative AKI and CKD progression, respectively, with a median follow-up period of 51.5 months. The median preoperative serum albumin level and eGFR were 4.1 g/dL and 82.0 mL/minute/1.73 m 2 , respectively. Preoperative serum albumin less than the median (4.1 g/dL) was associated with postoperative AKI (odds ratio [OR] 3.76, p=0.027) and CKD progression (OR 2.87, p<0.001) after adjusting for other factors. Conclusions Serum albumin level <4.1 g/dL was associated with short- and long-term renal function decline after RC, suggesting that close monitoring of renal function after RC might be considered in these patients.

Previous studies investigating prostate cancer (PCa) features in younger men have reported conflicting findings. This study aimed to investigate pathologic outcomes and biochemical recurrence (BCR) status in younger men who underwent radical prostatectomy (RP) for PCa. Records of 2057 patients who underwent RP at Seoul National University Bundang Hospital (Seongnam, Korea) between 2006 and 2015 were reviewed; patients were divided according to age into the younger and older groups (men aged ≤50 and >50 years, respectively). Postoperative BCR status and functional outcomes and clinicopathologic features were compared between both groups. All analyses were repeated after propensity score matching. Younger men were more likely to have low-risk disease (P < 0.001), lower pathologic Gleason score (P < 0.001) and pathologic stages (P < 0.001) than older men. The pathologic Gleason score (P = 0.002) and rates of extracapsular extension (P = 0.004) were lower in younger men after propensity score matching. In multivariate analysis, age at RP was not an independent predictor of BCR-free survival after RP (P = 0.669). Moreover, at 1 year after RP, younger men with preoperative 5-item International Index of Erectile Function score ≥22 (n = 228) showed more favorable results for urinary continence (defined as nonuse of pads daily) (99.4% vs 95%, P = 0.009) and erections sufficient for vaginal intercourse (81.8% vs 55.5%, P = 0.001). Younger men had more favorable clinicopathologic features at RP than their older counterparts. Although age was not an independent predictor of BCR status outcome, younger men had better functional outcomes following RP.

PURPOSE: We aimed to study clinicopathological parameters and complications of patients who underwent magnetic resonance imaging-transrectal ultrasonography fusion guided prostate biopsy (MRI-TRUS FGB). MATERIALS AND METHODS: We investigated 576 patients who underwent MRI-TRUS FGB of prostate from May 2003 to December 2017 retrospectively. The clinicopathological features and complications were presented, using the modified Clavien-Dindo classification system. RESULTS: Fourteen patients (2.4%) readmitted within 30 days after MRI-TRUS FGB due to complications, and 85.7% (12 of 14) of them complained mild to moderate complications, the Clavien-Dindo classification grades I and II. The most common complication was hematuria (n=5, 0.9%), followed by acute urinary retention (n=3, 0.5%), dysuria (n=2, 0.3%), fever (n=1, 0.2%), hematochezia (n=1, 0.2%). According to multivariate analysis, only age was the significant risk factor of overall complications and bleeding related complications. Two hundred thirteen patients were diagnosed as prostate cancer after MRI-TRUS FGB. When the Likert suspicious scale of prostate cancer on apparent diffusion coefficient (ADC) was ≤4, 27.8% (137 of 493) were diagnosed as prostate cancer, of whom 56.2% (77 of 137) were confirmed as prostate cancer only at randomized 12 cores. When the ADC suspicious level was grade 5, 91.6% (76 of 83) were diagnosed as prostate cancer, of whom 11.8% (7 of 76) were confirmed as prostate cancer only at randomized 12 cores. CONCLUSIONS: The present study demonstrates the safety of MRI-TRUS FGB in terms of complications. When ADC suspicious level is grade 5, MRI-TRUS FGB alone could be a reasonable measure to diagnose prostate cancer, but randomized 12-core prostate biopsy would be recommended additionally when ADC suspicious level is ≤4.

PURPOSE: The aim of this study is evaluating the accuracy of preoperative magnetic resonance imaging (MRI) in patients who underwent pelvic lymph node dissection (PLND). MATERIALS AND METHODS: The medical records of 1,528 patients who underwent radical prostatectomy and PLND from 2003 to 2017 in Seoul National University Bundang Hospital were retrospectively reviewed. We evaluated the various clinicopathologic variables including preoperative MRI findings and pathologic lymph node (LN) metastasis. The prediction model for pathologic LN metastasis was assessed using univariate and multivariable logistic regression analyses and areas under receiver operating characteristic (ROC) curves. RESULTS: The mean age of our cohort was 66.4±6.7 years. Positive LN finding of preoperative MRI finding was observed in 9.4% (145 of 1,528) of patients. 5.3% (81 of 1,528) of patients had confirmed final pathologic LN metastases. Sensitivity and specificity of preoperative MRI were 30.8% and 91.7%, respectively. Multivariable analysis showed that preoperative MRI findings, clinical stage and biopsy Gleason score were independent significant predictors for pathologic LN metastasis (p < 0.001, p=0.002, and p < 0.001, respectively). Prediction model using preoperative MRI findings and National Comprehensive Control Network risk stratification showed fair accuracy using ROC analysis. CONCLUSIONS: Preoperative MRI findings for pathologic LN metastasis showed limited prediction value. A large-scale, multicenter, prospective study is needed to fully evaluate the clinical significance of preoperative MRI.
