Objective: The objective of this study was to characterize exclusive costal lesions detected by 68 Gallium-labelled prostate-specific membrane antigen ([ 68 Ga]Ga-PSMA-11) PET/computed tomography (CT) at initial staging or biochemical recurrence (BCR) in prostate cancer (PCa) patients, and to identify clinical and/or PET/CT criteria associated with benign and malignant lesions.

Methods: We retrospectively identified 54 patients with PCa who underwent [ 68 Ga]Ga-PSMA-11 PET/CT for initial staging ( N  = 39) or BCR ( N  = 15) and whose reports described rib lesions, at the exclusion of any other lesions, whether doubtful, suspicious, or established. Posttherapy prostate-specific antigen (PSA) levels were used to determine whether those lesions were benign or malignant.

Introduction: Clean Intermittent Catheterization (CIC) is considered as a gold standard of treatment for bladder emptying disorders. A large amount of literature on CIC for patients suffering from neurological disorders is available, but there is a lack of research specifically concerning multiple sclerosis (MS) patients. Our primary outcome was to determine the characteristics of our population (sex, EDSS and age when CIC was introduced).

Urine cytology is a long-used technique for the detection of high grade neoplastic urothelial lesions. Since 2016, «The Paris System» classification has revolutionized this field by introducing a standardized terminology widely adopted by cytopathologists and urologists. In this article, we explain this classification and discuss its impact on the clinical management of patients with urothelial lesions, as well as its role in the secondary prevention of these lesions.

Radiation therapy after prostatectomy for a prostate cancer is a recommended treatment in case of biochemical relapse (rising PSA) following surgery. Controversies regarding its optimal use, delivery, and toxicities are often discussed, not only within scientific congresses but also during multidisciplinary oncological boards. This article aims at making an assessment of up-to-date knowledge and recommendations to guide decision making regarding the treatments of patients with prostate cancer.

Article Synopsis
  • - Zoon's balanitis is a rare skin condition affecting the genital area, typically showing as a red-orange spot with a "cayenne pepper" look, mostly in uncircumcised middle-aged to older men.
  • - It can sometimes present in atypical forms, such as lesions that are vegetative or ulcerative, and while it's usually benign, it can occur alongside other skin issues.
  • - Topical treatments often fail, and symptoms frequently return after stopping treatment, so circumcision is considered an effective option that usually leads to quick and complete relief from symptoms.

Background: Hemorrhagic cystitis (HC) with BK polyomavirus (BKPyV) is a common complication after allogeneic hematopoietic cell transplantation (alloHCT) that may lead to severe discomfort for the patient and significant morbidity (urinary obstruction, increased transfusion requirements and prolonged hospitalization). So far, there is no clear consensus on how to manage this complication.

Patients And Methods: Here, we report a single-center case series of 9 patients (4 children and 5 adults) treated with cidofovir endovesical (EV) instillation(s) for BKPyV-HC after alloHCT.

Dysregulated lipid metabolism is a prominent feature of prostate cancer that is driven by androgen receptor (AR) signaling. Here we used quantitative mass spectrometry to define the "lipidome" in prostate tumors with matched benign tissues ( = 21), independent unmatched tissues ( = 47), and primary prostate explants cultured with the clinical AR antagonist enzalutamide ( = 43). Significant differences in lipid composition were detected and spatially visualized in tumors compared with matched benign samples.

Background: Prostate-specific membrane antigen (PSMA) ligand PET/CT has already provided promising results in prostate cancer (PC) imaging, yet simple and reproductible reporting criteria are still lacking. This study aimed at retrospectively evaluating interobserver agreement of [Ga]Ga-PSMA-11 PET/CT images interpretation according to PC molecular imaging standardized evaluation (PROMISE) criteria and reproducibility of PSMA reporting and data systems (RADS).

Methods: Forty-three patients with newly diagnosed, histologically proven intermediate- or high-risk PC, eligible for radical prostatectomy and who underwent [Ga]Ga-PSMA-11 PET/CT before surgery were retrospectively included.

Article Synopsis
  • Researchers are looking for better ways to find bladder cancer early, using special markers found in urine.
  • They studied different genes in urine samples from over 300 patients to see if these markers could tell if someone has bladder cancer and how serious it is.
  • The best markers showed they can correctly identify bladder cancer about 76-77% of the time and could help doctors make better decisions without needing invasive tests.

Introduction: Despite no consensus on the optimal management of recurrent prostate cancer after primary radiation or HIFU therapy, salvage prostatectomy (sRP) is reserved for only 3% of patients because of technical challenges and frequent post-operative complications. We assessed outcomes after sRP in a series of patients with localized PCa and that had received radiation therapy or HIFU as a first-line treatment.

Materials And Methods: Data from nine French referral centers on patients treated with sRP between 2005 and 2017 were collected.

Tension-free suburethral tapes have revolutionized the surgical treatment of female stress urinary incontinence (SUI). These tapes are inserted by way of a retropubic or transobturator route. The inside-out tension-free vaginal tape transobturator approach, or TVT-Obturator system (TVT-O, Ethicon Women's Health and Urology, Somerville, NJ), was developed ten years ago with the aim of minimizing the risk of urinary tract injuries associated with retropubic and outside-in transobturator tapes while reproducibly ensuring minimal tissue dissection.
