Gas-containing renal stones: a red flag for renal infection.

2022

Background Gas in the renal excretory system is described as a consequence of recent procedures but it can be a sign of severe conditions such as fistulas or infections; however, gas-containing renal stones are only rarely encountered. Purpose To describe the association of gas-containing renal stones and urinary tract infection. Material and Methods We performed a retrospective evaluation of the clinical and imaging findings in a series of six patients with gas-containing renal stones and compared our findings with those of patients with gas-containing renal stones reported in the literature. Urine and stone cultures were used as a diagnostic standard for urinary tract infection. Results I…

Handling and pathology reporting of specimens with carcinoma of the urinary bladder, ureter, and renal pelvis.

2003

Abstract Objective: Pathologists play a pivotal role in the diagnosis and in the report of the pathological features related to prognosis. Methods: To meet these endpoints, the following issues must be accomplished: adequate information about the patient history, proper handling of the specimens, identification of the reliable histopathological techniques necessary to reach the more detailed diagnostic information and evaluate the prognostic variables, and a standardized pathological report. Results: Recent efforts to standardize the histopathological evaluation have generated significant confusion among the urological and pathological communities as well. No consensus has been achieved abo…

Ultrasound imaging of the pelvic floor: Where are we going?

2011

We produced a non systematic review of ultrasound imaging of the pelvic floor in women with urinary incontinence (UI) and/or pelvic organ prolapse (POP). We have searched the PubMed and Embase databases for the following PICO question: women; imaging; urinary incontinence, pelvic organ prolapse, pelvic floor, pelvic floor muscle, pelvic floor muscle training; physical examination, no imaging; diagnosis, prognosis, outcome. The production of a systematic review was deemed impossible based on the type and quality of the published evidence. Clinical research focused on the pathophysiology of the UI and POP looking relation between anatomic abnormalities, childbirth, the risk of UI or POP, the …

Localization of small islet-cell tumors. Preoperative and intraoperative ultrasound, computed tomography, arteriography, digital subtraction angiogra…

1985

A total of 42 islet-cell tumors were examined between 1972 and 1984. Problems of localization were only encountered in 31 tumors less than 2 cm in diameter. Of 31 small tumors, 27 were correctly localized using a combined diagnostic approach: ultrasound was successful in 12/20 tumors, CT in 9/21, angiography in 20/31, intraarterial digital subtraction angiography in 1/2, and pancreatic venous sampling in 13/16. The smallest tumor found by ultrasound and CT was 7 mm in diameter. Intraoperative ultrasound demonstrated all 9 insulinomas examined. Currently, the most useful techniques for localizing small islet-cell tumors are ultrasound, CT, and angiography. CT is particularly useful for tumor…

CT and MR imaging of chemotherapy-induced hepatopathy.

2019

Chemotherapy-induced hepatopathy includes a wide variety of parenchymal and vascular hepatic changes on imaging, including diffuse or focal hepatopathies (i.e. hepatitis, steatosis, fibrosis, pseudocirrhosis, or sinusoidal obstruction). These changes can profoundly alter the hepatic parenchyma on imaging and result in both false negative and false-positive diagnoses of hepatic metastases and lead to errors in patient management strategies. It is therefore important for radiologists to have a comprehensive knowledge of the imaging patterns that may develop following chemotherapy. The purpose of this review is to explore the broad spectrum of hepatic parenchymal and vascular chemotherapy-indu…

Results of conservative treatment (transurethral resection plus adjuvant intravesical chemotherapy) in patients with primary T1, G3 transitional cell…

1996

Objectives. To evaluate a selected population of 50 consecutive patients with primary T1, G3 bladder transitional cell carcinoma in the absence of carcinoma in situ (Tis) treated with a bladder-sparing approach. Methods. Between January 1983 and December 1992, all patients were treated by transurethral resection (TUR) plus adjuvant intravesical chemotherapy over 1 year. In most cases, doxorubicin, epirubicin, and mitomycin were used alone or in combination. Results. At a mean follow-up period of 52 months (range, 18 to 126), 16 of 50 patients (32%) showed a recurrent superficial tumor. The recurrent lesion was of Stage T1 in 11 (22%) cases, but was a T1, G3 tumor only in 5 cases (10%). In 2…

Sentinel lymph node imaging in urologic oncology

2018

Lymph node (LN) metastases in urological malignancies correlate with poor oncological outcomes. Accurate LN staging is of great importance since patients can benefit from an optimal staging, accordingly aligned therapy and more radical treatments. Current conventional cross-sectional imaging modalities [e.g., computed tomography (CT) and magnetic resonance imaging (MRI)] are not accurate enough to reliably detect early LN metastases as they rely on size criteria. Radical lymphadenectomy, the surgical removal of regional LNs, is the gold standard of invasive LN staging. The LN dissection is guided by anatomic considerations of lymphatic drainage pathways of the primary tumor. Selection of pa…

ICUD-EAU International Consultation on Bladder Cancer 2012: Non–Muscle-Invasive Urothelial Carcinoma of the Bladder

2012

Item does not contain fulltext CONTEXT: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. OBJECTIVE: To critically review the recent data on the management of NMIBC to arrive at a general consensus. EVIDENCE ACQUISITION: A detailed Medline analysis was performed for original articles addressing the treatment of NMIBC with regard to diagnosis, surgery, intravesical chemotherapy, and follow-up. Proceedings from the last 5 yr of major conferences were also searched. EVIDENCE SYNTHESIS: The major findi…

Vacuum inversion and securing of distal colonic pseudodiverticula with novel spiked O-rings

2015

Background Diverticular disease is increasingly prevalent in Western societies and is associated with significant morbidity. Objective Two-stage endoscopic device development for inversion and secured ligation of colonic diverticula; first, human cadaver studies were performed to measure forces required for diverticular inversion; second, a novel set of devices (elastic spiked O-ring with delivery system) was tested in animals. Design Prospective, observational study of human cadavers and prospective, interventional study of a porcine model. Setting University hospital pathology laboratory and animal facility. Intervention Full-thickness inversion of the colonic wall with a pipelike deliver…
