Operative and oncological results and impact on treatment strategy of systematic renal tumor biopsy: Comparison between patients < and >75 years old.

Background: Proper usage of renal tumor biopsy (RTB) remains to be determined in the setting of renal tumors diagnosis, particularly in the elderly population. The aim of the study was to evaluate the perioperative and pathological results of RTB in a population of patients over 75 and to compare the performance of the procedure to their younger counterparts.

Material And Methods: Systematic RTB were prospectively performed in a single center between 2009 and 2012.

Peri-operative and local control outcomes of robot-assisted partial nephrectomy vs percutaneous cryoablation for renal masses: comparison after matching on radiological stage and renal score.

Objectives: To compare the oncological outcomes of percutaneous cryoablation (PCA) vs robot-assisted partial nephrectomy (RAPN) for the treatment of T1 renal tumours.

Patients And Methods: We conducted a retrospective study in all patients treated by RAPN or PCA for malignant renal tumours in one of four centres between 2009 and 2016. Tumours were paired one by one using radiological tumour stage and RENAL nephrometry score (package matchit, R software version 3.

[Cryoablation under local anesthesia of renal tumors].

Cryoablation under local anesthesia of renal tumors. The incidence of small renal tumors is increasing. These small tumors measuring less than 4 cm are typically slow-growing.

Diffusion-weighted imaging of the prostate: should we use quantitative metrics to better characterize focal lesions originating in the peripheral zone?

Purpose: To compare inter-reader concordance and accuracy of qualitative diffusion-weighted (DW) PIRADSv2.0 score with those of quantitative DW-MRI for the diagnosis of peripheral zone prostate cancer.

Materials And Methods: Two radiologists independently assigned a DW-MRI-PIRADS score to 92 PZ-foci, in 74 patients (64.
