Imaging protocols for renal multiparametric MRI and MR urography: results of a consensus conference from the French Society of Genitourinary Imaging.

Objectives: To develop technical guidelines for magnetic resonance imaging aimed at characterising renal masses (multiparametric magnetic resonance imaging, mpMRI) and at imaging the bladder and upper urinary tract (magnetic resonance urography, MRU).

Methods: The French Society of Genitourinary Imaging organised a Delphi consensus conference with a two-round Delphi survey followed by a face-to-face meeting. Two separate questionnaires were issued for renal mpMRI and for MRU.

Clear Cell Papillary Renal Cell Carcinoma: A Recent Entity With Distinct Imaging Patterns.

Clear cell papillary renal cell carcinoma (RCC), an entity with strikingly indolent behavior, recently was added to the World Health Organization classification of renal tumors and represents the fourth most common histologic type of renal cell carcinoma. This article aims to describe the imaging features of clear cell papillary RCC along with its clinical and pathologic characteristics. This retrospective study consisted of 27 patients with 44 clear cell papillary RCC tumors.

Spontaneous gas in a retroperitoneal mass: check the testis!

Testicular germ cell tumor is the most common cancer in 20-to 35-years-old men. There are known risk factors such as undescended testicle(s) and history of testicular cancer. Most lesions are germ cell tumors with two main subtypes: seminomas and non-seminomatous germ cell tumors.

Renal Pseudo-tumor Related to Renal Splenosis: Imaging Features.

Objective: To report the case of a 29-year-old patient presenting with renal splenosis along with a complete review of literature on this condition. Splenosis is a frequent condition following abdominal trauma or splenectomy, described as splenic tissue that autotransplants into a heterotopic location. However, renal splenosis is rare and often mistaken with renal carcinoma.

Calcified Renal Angiomyolipoma: A Case Report.

We report the case of a calcified angiomyolipoma of the kidney, fortuitously discovered on a computed tomography scan of the abdomen. Because of the presence of intratumoral calcification and macroscopic fat, renal cell carcinoma could not be ruled out by imaging. Biopsy of the mass was performed, and pathological study confirmed the diagnosis of angiomyolipoma.

Optimization of 64-MDCT urography: effect of dual-phase imaging with furosemide on collecting system opacification and radiation dose.

Objective: The purpose of this study was to compare opacification of the urinary collecting system and radiation dose associated with three-phase 64-MDCT urographic protocols and those associated with a split-bolus dual-phase protocol including furosemide.

Materials And Methods: Images from 150 CT urographic examinations performed with three scanning protocols were retrospectively evaluated. Group A consisted of 50 sequentially registered patients who underwent a three-phase protocol with saline infusion.

Hybrid tumour 'oncocytoma-chromophobe renal cell carcinoma' of the kidney: a report of seven sporadic cases.

Objectives: To determine whether renal hybrid tumours (HT) appear as a specific clinical and radiological entity, as HT are characterized by the association of both oncocytes and chromophobe cells within the same tumour, and have been described in patients with oncocytosis and Birt-Hogg-Dube syndrome.

Patients And Methods: We reviewed the medical charts of 67 patients who had a partial or radical nephrectomy in our institution for renal oncocytoma (RO, 24), chromophobe renal cell carcinoma (CRCC, 36) and HT (seven), from January 2006 to October 2007. We report the clinical, radiological and pathological characteristics of the seven cases of HT.

[Laparoscopic kidney release for refractory chyluria].

Chyluria is a rare disease outside of parasite endemic zones. The treatment of severe forms is surgical. Reno-lymphatic disconnection is the reference procedure, with long-term success rates of 99%.

[Imaging of cancer prostate].

Imaging of prostate cancer relies mainly on ultrasonography (US) and magnetic resonance imaging (MRI). It plays a diagnostic role in detecting and staging prostate carcinomas. Prostate biopsies are performed under endorectal US guidance at best with additional colour Doppler information.
