New transperineal ultrasound-guided biopsy for men in whom PSA is increasing after Miles’ operation

Biopsy procedures All patients fasted for 6 h. They took oral antibiotics from one day before the biopsy to 6 days post-biopsy. All patients were laid in a left decubitus and knee-chest position. An end-fire endo-cavity transducer (5–9 MHz or 4–10 MHz) was placed in contact with the perineum by the same radiologist who had interpreted the pre-biopsy MR images (Table (Table1)1) and had 11 years of experience with prostate biopsies prior to the first case 2009. First, the prostate urethra was searched as a landmark in the sagittal planes by pushing a transducer to the perineum (Fig. 1D). Then, the radiologist scanned the entire prostate to localize the index tumor detected on MRI (Fig. 1E). After tumor localization, the perineum was sterilized with alcohol and anesthetized with a total of 5–10 mL of 2% lidocaine, which was repeatedly injected along the biopsy path until the patient no longer complained of pain. An 18-gage automated co-axial needle (ACECUT; TSK Laboratory, Tochigi-shi, Japan) was introduced into a guider placed on the transducer (Fig. 1F). The needle tip was placed as close to the index tumor as possible. All biopsy cores were multi-focally sampled within the tumor except for two cases in which one core was obtained. The biopsy tracts were easily detected because they were mostly hyperechoic in the TPUS images.

Novel CT-derived biomarkers for prediction of renal split function in preoperative nephrectomy planning

In this pilot study of adult patients undergoing nephrectomy, we show good correlation between novel CT- and nuclear medicine-derived estimates of renal split function, although both underestimate post-operative renal function compared to actual GFR values.

Pelvic and extra-pelvic endometriosis: a review of indications, techniques and MRI features.

Endometriosis is a chronic disease presenting with a wide range of symptoms and manifestations. Imaging plays a crucial role in the diagnosis of this disease, and, in particular, MRI allows an accurate evaluation of the different features of endometriosis.

Pelvic floor disorders: don’t forget men!

Pelvic floor disorders usually prevail in female population, but also in men can lead to debilitating pathologies with a significant reduction of quality of life. Causes can be patient related, iatrogenic (postsurgical /postradiation), traumatic or due to a pathological increase of abdominal pressure. Posterior compartment disorders are quite similar to the female counterpart, while anterior compartment diseases are more sex-specific. In male the most frequent disorders occur after prostate cancer treatment, such as post-prostatectomy urinary incontinence and erectile dysfunction. Pelvic floor muscles (puborectalis and ischiocavernosus) play important roles in the regulation of continence and erectile mechanisms and can be well detected by MR Defecography. This imaging technique is frequently used in studying female pelvic floor disorders but less performed in male pathologies despite its evident value, in this contest. MR study provides important anatomic and functional information about pelvic floor muscles, quantifying post-surgical and post-radiation changes, helping in the planning of repair treatment. Muscular structures integrity is evaluated as well as a quantification of pelvic organ descent is reported, using specific male pelvic floor landmarks.

Pelvic venous congestion syndrome (PVCS) in women: a neglected pathology

Pelvic venous congestion syndrome (PVCS) is a common and still overlooked cause of chronic pelvic pain (CPP). Other symptoms, yet aspecific, of PVCS include dyspareunia, dysmenorrhea, and urinary urgency. The etiology of PVCS includes, to name a few, pelvic venous insufficiency (PVI), retro-aortic left vein, Nutcracker syndrome and May-Thurner syndrome. Currently, there is no consensus on diagnostic algorithms, nor the treatment management of PVCS. Ultrasonography (US) is considered the first line imaging study; the criteria proposed by Coakley can be used for its diagnosis with Computed Tomography (CT) and Magnetic Resonance (MR) with time resolved imaging (TRI). Venography remains the gold standard but invasive and normally reserved for patients who are selected for interventional treatment.
