A comparison of transrectal ultrasound (TRUS) and computed tomography (CT) for staging of rectal carcinoma was performed. Thirty-two patients were examined by TRUS and 30 by CT. The results of these preoperative examinations were compared with postoperative histopathological findings. TRUS had an accuracy of 81% and it predicted perirectal tumor growth with a sensitivity of 90% and a specificity of 67%, whereas the corresponding figures for CT were 52%, 67%, and 27%. These findings indicate that TRUS is more efficient than CT in staging local tumor growth in rectal cancer. Neither technique, however, can reliably identify lymph node metastases, since no correlation was found between lymph node size as observed on CT and TRUS and tumor involvement as evaluated histopathologically.

The aim of this study was to determine and compare the diagnostic accuracies of two commercial pregnancy-associated glycoprotein tests, Alertys OnFarm Pregnancy Test (AOPT) and Alertys Milk Pregnancy Test (AMPT), for early pregnancy diagnosis in dairy cattle. Holstein cows (n = 124) were used in the study. Whole blood samples were collected from the jugular vein 28 days after fixed-time artificial insemination (FTAI).

Pelvic Venous Disorder (PEVD) and May-Thurner syndrome (MTS) represent relatively understudied vascular issues that can significantly impact patients' quality of life. This study aims to evaluate the efficacy of surgical treatment for PEVD and MTS, conduct a comparative analysis of outcomes, and determine the practical significance of different therapeutic approaches. The study was conducted from 2019 to 2022 in Moscow, Russia, encompassing two outpatient clinics.

: Multiparametric-Magnetic Resonance Imaging(mp-MRI) presents the ability to detect clinically significant cancer, aiming to avoid biopsy if the results are negative or target an abnormal lesion if a suspected lesion of the prostate is found. Recent guidelines recommend the performance of 12 standard biopsies along with 3 to 5 targeted biopsies in suspected prostate lesions, depending on the size of the prostate lesion. In addition, prostate biopsy can be performed by either the transperineal or the transrectal approach.

Background: The relationship between case volume and clinical outcomes is well established for most urological procedures but remains underexplored in prostate ultrasound/MRI fusion biopsy (UMFB). UMFB aims to detect clinically significant prostate cancer (csPCa) by adhering to cancer detection benchmarks for PI-RADS lesions identified via multiparametric MRI (mpMRI). These benchmarks, defined by Ahmed et al.

Objective: To assess the association between prostate-specific antigen (PSA) density (PSAD) and prostate cancer mortality after a benign result on systematic transrectal ultrasonography (TRUS)-guided prostate biopsy.
Patients And Methods: This retrospective study used data from the Finnish Randomised Study of Screening for Prostate Cancer (FinRSPC) collected between 1996 and 2020. We identified men aged 55-71 years randomised to the screening arm with PSA ≥4.
