OBJECTIVE: This article discusses scrotal ultrasonic features of patients with a congenital bilateral absence of the vas deferens (CBAVD). METHODS: Thirty-six patients with CBAVD were examined to obtain image characteristics of the bilateral testicle and epididymis by ultrasound. Each patient received a pathological examination of the sperm by percutaneous epididymal biopsy. RESULTS: Scrotal ultrasonic features were as follows: (1) testicular volumes were normal in all the 36 patients; (2) 21% (15/72) of the heads of epididymis, 67% (48/72) of the heads and bodies of epididymis, and 12% (9/72) of the heads, bodies, and tails of epididymis could be shown in the 72 epididymides of the 36 patients; (3) cystic or tubular dilation of the epididymis was obvious in all 72 abnormal epididymides; and (4) bilateral vas deferens could not be found in these patients...

OBJECTIVES: The incidence of pneumothorax is 7 times higher after lung radiofrequency ablation (RFA) than after lung biopsy. The reasons for such a difference have never been objectified. The histopathologic changes in lung tissue are well-studied and established for RF in the ablation zone. However, it has not been previously described what the nature of thermal injury might be along the shaft of the RF electrode as it traverses through normal lung tissue to reach the ablation zone. The purpose of this study was to determine the changes occurring around the RF needle along the pathway between the ablated zone and the pleura...

This study aimed to investigate the feasibility of the establishment of a human cancer xenograft model using samples from computed tomography (CT)-guided percutaneous biopsy. Fresh tumor tissues obtained from 10 cancer patients by CT-guided percutaneous biopsy were subcutaneously inoculated into NOD-Prkdcem26Il2rgem26Nju (NCG) mice to establish human patient-derived tumor xenograft (PDTX) models. The formation of first and second generation xenografts was observed, and tumor volume was recorded over time. Tumor tissue consistency between the PDTX model and primary tumors in patients was compared using H&E staining and immunohistochemistry...

BACKGROUND/AIMS: Bleeding is the most common complication after renal biopsy. Although numerous predictors of bleeding have been reported, it remains unclear whether arterial stiffness affects bleeding complications. METHOD: We performed an observational study of the renal biopsies performed in our division over an approximately 6-year period (May 2010 to May 2016). The clinical and laboratory factors were analyzed to reveal the risk factors associated with bleeding, with a focus on anemia (defined as a ≥10% decrease in hemoglobin [Hb] after biopsy)...

Systemic lupus erythematosus (SLE) is characterized by a multifaceted pathogenesis and a heterogeneous clinical expression. The kidney involvement is almost unavoidable in all forms of SLE with chronic evolution, 75% of patients developing renal lesions defined as lupus nephritis (LN) - a glomerulonephritis with an extremely diverse lesion spectrum. The present study aimed to reevaluate a series of cases diagnosed as LN, focusing on the histological features in correlation with the level of activity and chronicity...

PURPOSE: Pyelonephritis, an upper urinary tract infection, is a serious infection that often requires hospitalization. However, the accurate diagnosis of acute pyelonephritis can be difficult, especially among older individuals who can present with unusual symptoms. Imaging with computed tomography (CT) is not unusual in the diagnosis of pyelonephritis, with some clinicians regarding perirenal fat stranding (PFS) as a characteristic finding. However, the sensitivity and specificity of PFS in diagnosing pyelonephritis are currently unknown...

Percutaneous image-guided biopsies of pancreatic malignancies may prove challenging and nondiagnostic due to a variety of anatomic considerations. For patients with complex post-surgical anatomy, such as a Roux-en-Y gastric bypass, diagnosis via endoscopic ultrasound with fine-needle aspiration may not be possible because of an inability to reach the proximal duodenum. This report describes the first diagnostic case of transbiliary intravascular ultrasound-guided biopsy of a pancreatic head mass in a patient with prior Roux-en-Y gastric bypass for which a diagnosis could not be achieved via percutaneous and endoscopic approaches...

RATIONALE: Psoas abscesses generally arise from a contiguous intra-abdominal or pelvic infectious process or hematogenous spreading of bacteria. The serum β-human chorionic gonadotropin has been used to detect normal or ectopic pregnancy. It also can be utilized in following up carcinomas. PATIENT CONCERNS: Here, we reported a case of a 47-year-old woman who presented with a left psoas mass presumptively diagnosed as an abscess secondary to lumbar tuberculosis In addition, the patient had abnormal increase of β-human chorionic gonadotropin...

Percutaneous drainage of the bile ducts is an established procedure for malignant obstructions, in which a histological diagnosis is often not obtained. We describe the biopsy technique of obstructive lesions through biliary drainage access, using a 7F endoscopic biopsy forceps, widely available; some are even reusable. This technique applies to lesions of the hepatic ducts, of the common hepatic duct and of all extension of the common bile duct. RESUMO A drenagem percutânea das vias biliares é um procedimento estabelecido para obstruções malignas, nos quais, muitas vezes, não se consegue um diagnóstico histológico...
