Which is the best radiological imaging method for predicting actual prostate weight?

In this study, we compared the weight of the prostate specimen removed after robotic radical prostatectomy with the prostate weight measured pre-operatively by four different imaging modalities. Pre-operative prostate weight before robotic radical prostatectomy was measured by Transabdominal Ultrasonography (TAUS), Transrectal Ultrasonography (TRUS), Abdominal Tomography (CT) and MultiparametricProstate Magnetic Resonance imaging (mpMRI). Of the 170 patients enrolled in the study, the mean age was 65.

Patients whose testosterone level is lower than 280ng/ml or who had undergone radical prostatectomy were excluded from the analysis.

Diagnosis and Conservative Management of Ureteral Orifice Injury During Robotic Prostatectomy for a Large Prostate with a Prominent Median Lobe.

Robot-assisted laparoscopic radical prostatectomy (RALRP) is now considered the standard treatment for localized prostate cancer. However, challenges may arise when dealing with large prostates with a prominent median lobe because the ureteral orifices may not always be visible during dissection and maybe injured in the process. We describe our experience on the diagnosis and conservative management of ureteral orifice injury in this situation.

Prognostic significance of the programmed death ligand 1 expression in clear cell renal cell carcinoma and correlation with the tumor microenvironment and hypoxia-inducible factor expression.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common renal malignancy. Hypoxia-inducible factors, HIF-1α and HIF-2α, are expressed in the majority of ccRCC. Targeting immune checkpoints with the blockade of PD-1 and its ligand PD-L1 reorganizes T-cell activity in tumor microenvironment and provides important antitumor responses.
