Risk Factors for Testicular Cancer: Environment, Genes and Infections-Is It All?

: The incidence of testicular cancer is steadily increasing over the past several decades in different developed countries. If on one side better diagnosis and treatment have shone a light on this disease, on the other side, differently from other malignant diseases, few risk factors have been identified. The reasons for the increase in testicular cancer are however unknown while risk factors are still poorly understood. Several studies have suggested that exposure to various factors in adolescence as well as in adulthood could be linked to the development of testicular cancer. Nevertheless, the role of environment, infections, and occupational exposure are undoubtedly associated with an increase or a decrease in this risk. The aim of this narrative review is to summarize the most recent evidence regarding the risk factors associated with testicular cancer, starting from the most commonly evaluated (cryptorchidism, family history, infections) to the newer identified and hypothesized risk factors

Renal angiomyolipoma with renal vein invasion

Renal angiomyolipoma is a uncommon benign tumor, considered an hamartoma. The lesion, usually benign, can be single or multiple and well-circumscribed. In letterature only few cases of infiltrating angiomyolipomas have been described. The aim of the paper is to describe a paradigmatic case of a giant kidney angiomyolipoma, not associ- ated with tuberous sclerosis, invading the pelvis and the renal vein. The lesion have been discovered incidentally during abdominal ultrasound for other pathology. Owing to the extent of the lesion and the appreciable risk of bleeding, we opted for surgical treatment

The Robotic Intracorporeal Vesuvian Orthotopic Neobladder (VON)—A New Technique for Continent Urinary Diversion: Initial Experience and Description of the Technique

Orthotopic neobladder reconstruction is becoming an increasing option as a urinary diversion following cystectomy for bladder cancer. The purpose of the following article is to describe, step-by-step, our technique for the robotic intracorporeal neobladder, the Vesuvian Orthotopic Neobladder. The primary aim of this new surgical procedure is to simplify and speed up the reservoir reconstruction, while at the same time obtaining an appropriate reservoir capacity. The Vesuvian Orthotopic Neobladder was performed employing an intestinal tract of 36 cm which was successively shaped in order to form a reservoir with three horns (left, right, and caudal), formed via the use of a mechanical stapler. Both ureters were stented and anastomosed to the left and right horn while the urethral-neobladder anastomosis was performed with the caudal horn. In this initial experience, two male patients with non-metastatic muscle-invasive bladder cancer underwent radical cystectomy followed by Vesuvian Orthotopic Neobladder reconfiguration. The mean age was 58.5 ± 3.53 years while the mean overall operative time was 435 ± 35.35 min, with an average neobladder reconstruction time of 59 ± 4.24 min. No intraoperative or postoperative complications were reported. The new intracorporeal Vesuvian Orthotopic Neobladder technique is a feasible and good alternative to traditional robotic intracorporeal orthotopic bladder procedures, permitting us to reduce operative time and obtain a neobladder with a fair reservoir capacity

Pyonephrosis Ultrasound and Computed Tomography Features: A Pictorial Review

Urinary tract infections (UTIs) are the most frequent community-acquired and healthcare-associated bacterial infections. UTIs are heterogeneous and range from rather benign, uncomplicated infections to complicated UTIs (cUTIs), pyelonephritis and severe urosepsis, depending mostly on the host response. Ultrasound and computed tomography represent the imaging processes of choice in the diagnosis and staging of the pathology in emergency settings. The aim of this study is to describe the common ultrasound (US) and computed tomography (CT) features of pyonephrosis. US can make the diagnosis, demonstrating echogenic debris, fluid/fluid levels, and air in the collecting system. Although the diagnosis appears to be easily made with US, CT is necessary in non-diagnostic US examinations to confirm the diagnosis, to demonstrate the cause and moreover to stage the pathology, defining extrarenal complications. In emergency settings, US and CT are differently used in the diagnosis and staging of pyonephrosis

MDCT Diagnosis and Staging of Xanthogranulomatous Pyelonephritis

Background: Benign nephrectomy to treat patients with renal inflammatory disease in cases of severe urinary infection represents a diagnostic and management challenge because of significant inflammatory, fibrotic, and infectious components. Among renal inflammatory diseases, fistulization and invasiveness to adjacent structures are some of the hallmarks of xanthogranulomatous pyelonephritis (XGP). The aims of this study were as follows 1. to retrospectively determine key demographic and clinical features of XGP among benign nephrectomies; 2. to assess the CT preoperative diagnostic accuracy; and 3. to define the imaging characteristics of the CT stage. Material and Methods: A retrospective review of clinical, laboratory, and radiological features and operative methods of patients who underwent benign nephrectomy with histologically proven XGP was performed. Results: XPG was diagnosed in 18 patients over a 4-year (2018–2022) period. XGP represented 43.90% among benign nephrectomies. The mean age of the patients was 63 years, and the sex prevalence was higher in women (72.22%). Symptoms were vague and not specifically referrable to urinary tract disorders and unilateral (100%), with the left kidney affected in 61.11% of cases. Staghorn calculi and stone disease were the most common underlying cause (72.22%). All patients underwent CT. The preoperative CT imaging accuracy for renal inflammatory disease was 94.44% and indeterminate in 5.56%. A suspected diagnosis of XGP was formulated in 66.67% (12/18; 2 stage II/10 stage III), meanwhile, in 33.33% (6 patients with stage I), a non-specific diagnosis of renal inflammatory disease was formulated. CT was reported according to the Malek and Elder classification and staged in the stage I nephric form (33.33%), stage II perinephric form (11.11%), stage III paranephric form (55.56%). Conclusions: The CT diagnostic accuracy for kidney inflammatory disease was extremely high, whereas the suspected diagnosis of XGP was formulated preoperatively in only 66.67% of high-stage disease, where the hallmarks of invasiveness and fistulization of the pathology increased the diagnostic confidence

Abnormal presentation of a bilateral, synchronous and plurimetastatic medium and large cell testicular lymphoma: A case report

Primary testicular lymphoma (PTL) accounts for 1-2% of all cases of non-Hodgkin's lymphoma, with a higher incidence in patients aged >60 years. The most common histological subtype is diffuse large-cell B lymphoma. By contrast, the bilateral synchronous and multimetastatic clinical presentation is a rare and unusual clinical presentation. In testicular masses, orchiectomy is essential for histopathological evaluation of the disease and definition of the immunophenotypic structure. The present study reported the case of a paucisymptomatic 54-year-old patient, who presented with erectile dysfunction and increasing testicular volume. Although clinical assessment and ultrasound examination showed an abnormal structure, highly suspicious for testicular cancer, the subsequent bilateral radical orchiectomy permitted the diagnosis of an unusual and rare PTL with multiple metastases reported at the PET/CT scan. In conclusion, the rare and aggressive disease represented by PTL requires a multidisciplinary approach and an aggressive treatment in order to provide the best care for patients affected
