Transrectal ultrasound is uniquely useful in diagnosing and localizing the extent of lower colon and rectal disease. This paper reports the preliminary evaluation of three-dimensional intraluminal ultrasound imaging of normal and diseased rectal segments. The three-dimensional reconstructions were produced using a computerized PC based image analysis system which aligns ultrasound images to produce the three-dimensional images. A unique perspective for displaying both normal and pathologic anatomy is achieved using this new technology and the method has promising diagnostic and therapeutic potentials.

Introduction: Gallium-68 prostate-specific membrane antigen positron emission tomography (Ga-PSMA PET) is being increasingly used in patients with prostate cancer (PCa) for the staging and detection of lymph node (LN) metastases, despite a lack of prospective, validated evidence. We aimed to investigate the relationship between the PSMA PET findings (maximum standardized uptake [SUV] value) and the final histopathology results (Gleason Grade [GG], and LN positivity) in patients undergoing radical prostatectomy.
Methods: This is a single centre, prospective, observational study of 63 consecutive eligible patients treated at a tertiary care centre in India.

Introduction: Recently, the Prostate Imaging Reporting and Data System - 3 lesions (PI-RADS 3) have been sub classified into "3a" - lesions with a volume of <0.5 mL and "3b" - lesions exceeding 0.5 mL, whereas the prostate-specific antigen density (PSAD) is an established adjunct tool for predicting clinically significant prostate cancer (csPCa).

Transrectal shear wave elastography (T-SWE) can be used non-invasively to diagnose prostate cancer (PCa) and benign prostatic hyperplasia (BPH). The prostate tissue can be viewed as an ellipsoidal sphere with viscoelastic characterization. Linear elastic model has been used to characterize soft tissues, and the simplification of partial characterization provides incomplete information.

Objective: To evaluate the outcomes and efficacy of robot-assisted radical prostatectomy (RARP) using the Versius robotic surgical system, aiming to provide comprehensive data on perioperative outcomes, postoperative recovery, and complications.
Patient And Methods: All cases of RARP using the CMR Versius platform performed at Cairo University Hospital over a two-year period were enrolled in this study. All patients had pathologically confirmed prostate cancer in both localized and locally advanced stages.
Background And Objective: To assess whether conventional brightness-mode (B-mode) transrectal ultrasound images of the prostate reveal clinically significant cancers with the help of artificial intelligence methods.
Methods: This study included 2986 men who underwent biopsies at two institutions. We trained the PROstate Cancer detection on B-mode transrectal UltraSound images NETwork (ProCUSNet) to determine whether ultrasound can reliably detect cancer.
