To evaluate the influence of prostate-specific antigen density (PSAD) on positive (PPV) and negative (NPV) predictive values of multiparametric magnetic resonance imaging (mpMRI) to detect Gleason score ≥7 cancer in a repeat biopsy setting. ⋯ In a repeat biopsy setting, a PSAD of ≤0.2 ng/mL/mL is associated with low detection of Gleason score ≥7 prostate cancer, not only in men with negative mpMRI, but also in men with equivocal imaging. Surveillance, rather than repeat biopsy, may be appropriate for these men. Conversely, biopsies are indicated in men with a high PSAD, even if an mpMRI shows no suspicious lesion, and in men with an mpMRI suspicious for cancer, even if the PSAD is low.

To improve risk stratification for recurrence prognostication in patients with localised clear cell renal cell carcinoma (ccRCC). ⋯ We developed a five-marker-based prognostic tool that can effectively classify patients with ccRCC according to risk of disease recurrence after surgery. This tool, if prospectively validated, could provide individualised risk estimation for patients with ccRCC.

Randomized Controlled Trial Comparative Study
A prospective and randomised trial comparing fluoroscopic, total ultrasonographic, and combined guidance for renal access in mini-percutaneous nephrolithotomy.
To compare the safety and efficacy of fluoroscopic guidance (FG), total ultrasonographic guidance (USG), and combined ultrasonographic and fluoroscopic guidance (CG) for percutaneous renal access in mini-percutaneous nephrolithotomy (mini-PCNL). ⋯ Mini-PCNL under USG is as safe and effective as FG or CG in the treatment of simple kidney stones (S.T.O.N.E. scores 5-6) but with no radiation exposure. FG or CG is more effective for patients with S.T.O.N.E. scores of 7-8, where multiple percutaneous tracts may be necessary.

Multicenter Study
Outcomes in patients with advanced urothelial carcinoma after discontinuation of programmed death (PD)-1 or PD ligand 1 inhibitor therapy.
To study the subsequent therapy and disease outcomes of patients with advanced urothelial carcinoma (UC) after discontinuation of programmed death-1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitors. ⋯ In this dataset, 35.5% of patients with advanced UC received systemic therapy after salvage therapy with PD-1/PD-L1 inhibitors. Outcomes after subsequent therapy appear similar to those historically observed in patients who had not received prior PD-1/PD-L1 inhibitor therapy. Further study of patients receiving post-PD-1/PD-L1 inhibitor therapy is warranted to identify factors associated with outcomes and potentially synergistic sequences.
