A Comparison of Functional and Oncologic Outcomes between Partial Nephrectomy and Radiofrequency Ablation in Patients with Chronic Kidney Disease after Propensity Score Matching.

Purpose: This study aimed to compare functional and oncological outcomes between partial nephrectomy (PN) and radiofrequency ablation (RFA) for a small renal mass (SRM, ≤4 cm) in patients with chronic kidney disease (CKD).

Materials And Methods: Patients with CKD who underwent either PN or RFA for SRM between 2005 and 2019 were included. Patients were stratified into two categories: CKD stage 2 and CKD stage 3 or higher.

Preoperative versus Postoperative Compensation of the Contralateral Normal Kidney in Patients Treated with Radical Nephrectomy for Renal Cell Carcinoma.

Background: We sought to identify the factors affecting renal compensatory processes that occur preoperatively as well as postoperatively in patients treated with radical nephrectomy (RNx) for renal cell carcinoma (RCC).

Methods: We retrospectively reviewed the records of 906 patients treated with RNx for RCC. We defined the early compensatory process (process 1) as compensatory adaptation of the contralateral normal kidney (CNK) before RNx.

Effects of Complete Bladder Cuff Removal on Oncological Outcomes Following Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma.

Purpose: This study aimed to evaluate the effects of bladder cuff method on oncological outcomes in patients who underwent radical nephroureterectomy (RNU) for upper tract urothelial carcinoma.

Materials And Methods: The records of 1,095 patients treated with RNU performed at our hospital between 1994 and 2018 were retrospectively reviewed; 856 patients with no bladder tumor history were enrolled in the present study. The management of bladder cuff was divided into two categories: extravesical ligation (EL) or transvesical resection (TR).

Detection of prostate cancer using prostate imaging reporting and data system score and prostate-specific antigen density in biopsy-naive and prior biopsy-negative patients.

Background: Few studies report on indications for prostate biopsy using Prostate Imaging-Reporting and Data System (PI-RADS) score and prostate-specific antigen density (PSAD). No study to date has included biopsy-naïve and prior biopsy-negative patients. Therefore, we evaluated the predictive values of the PI-RADS, version 2 (v2) score combined with PSAD to decrease unnecessary biopsies in biopsy-naïve and prior biopsy-negative patients.
