Effect of Bacillus Calmette-Guerin Exposure on Prostate Cancer Detection Using Magnetic Resonance Imaging: A Cohort Study.

Background: Granulomatous prostatitis is a medical condition that may mimic prostate cancer.

Purpose: Granulomatous prostatitis resulting from BCG-exposure can confound the diagnosis of prostate cancer based on prostate imaging and data system (PI-RADS) classification observed on multiparametric prostate magnetic resonance imaging (mpMRI).

Study Type, Population, Assessment And Statistical Tests: A cohort study was conducted, enrolling consecutive males at risk for prostate cancer who underwent an mpMRI-targeted prostate biopsy between February 2016 and August 2023.

Prevalence and grade of malignancy differences with respect to the area of involvement in multiparametric resonance imaging of the prostate in the diagnosis of prostate cancer using the PI-RADS version 2 classification.

Purpose: The peripheral zone is histologically different from the transitional zone. The aim of this study is to analyze the differences between the prevalence and grade of malignancy of mpMRI-targeted biopsies that involve the TZ with respect to the PZ.

Methods: A cross-sectional study of 597 men evaluated for PC screening between February 2016 and October 2022 was conducted.

Diagnostic evaluation and incorporation of PSA density and the prostate imaging and data reporting system (PIRADS) version 2 classification in risk-nomograms for prostate cancer.

Purpose: The diagnostic approach for prostate cancer still depends on PSA and DRE.

Objectives: to evaluate the diagnostic validity of PSA-Density and PIRADSv2 as diagnostic tests regarding biopsy results, and to design nomograms that include all diagnostic variables for malignancy, significant tumor (ST) and high-grade tumor.

Methods: Cross-sectional study which included men with PSA ≥ 4 ng/ml and/or suspicious DRE, PIRADSv2 ≥ 3 lesions on multiparametric MRI and prostate biopsy.

Comparative study between 1.5 and 3 Tesla multiparametric MRI systems using the PIRADS version 2 classification in the diagnosis of prostate cancer.

Introduction: The 3-Tesla multiparametric MRI (mpMRI) system represents a diagnostic advance for prostate cancer. Our aim is to demonstrate that the results in 1.5-Tesla mpMRI are not inferior compared to the 3-Tesla for the correct diagnosis of prostate cancer.

A rare case of penile metastases from small cell prostate cancer.

We present a case of an 83-year-old-male with painless penile nodules several months after he was diagnosed with pure prostatic small cell carcinoma. Penile doppler ultrasound and magnetic resonance imaging demonstrated solid nodules in both corpora cavernosa. Fine-needle aspiration of the nodules with immunohistochemical examination confirmed prostatic small cell carcinoma origin of metastases.

[Evaluation of the PI-RADSv2 classification in a cohort of patients who underwent a prostate fusion biopsy.].

Introduction: Prostate Fusion biopsy (MRI + prostate ultrasound) is described in literature as superior to classic random transrectal biopsy in order to identify suspicious lesion.

Objectives: To evaluate the Prostate Imaging Reporting and Data System (PI-RADS) proposed by the European Society of Urogenital Radiology (ESUR) for detection of prostate cancer by multiparametric MRI in a consecutive cohort of patients with MRI and transrectal ultrasound prostate fusion-guided biopsy.

Material And Methods: 87 patients with suspected Prostatic Cancer on prostate MRI underwent fusion transperineal prostate biopsy in our Department.

Bear Paw Sign: Xanthogranulomatous Pyelonephritis.

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis in which the involved areas of the kidneys are destroyed and replaced by foam cells. It usually occurs in immunocompromised middle-aged females with ureteral obstruction or chronic urinary tract infection induced by the formation of renal stones. We herein report the case of a 44-year-old woman, with a history of left kidney staghorn calculi and recurrent urinary tract infections.

[Analysis of success predictive factors in the treatment of urinary lithiasis by extracorporeal shock wave lithotripsy. patient optimization: ESWL score.].

Objective: Extracorporeal shock wave lithotripsy (ESWL) represents one of the most frequently used methods to treat urinary tract calculi. However, sometimes we do not obtain the fragmentation expected. The aim of this study is to evaluate the parameters that may influence ESWL final results, developing a classification for better patient's selection and outcome optimization.
