Pseudoaneurysm (PA) associated with an arteriovenous fistula (AVF) of the internal pudendal artery branches are very uncommon. We report a case of post-traumatic PA with AVF connected to Santorini plexus. Diagnosis was made with trans-rectal ultrasound (TRUS) after recurrent hematuria. TRUS reported a 1.7 × 1.4 × 1.5 cm anechoic area, on anterior prostate apex close to Santorini plexus. The use of color Doppler in this area revealed high flow velocity that was indicative for AVF. The feeding artery was a distal branch of the left pudenda artery...

Ga-PSMA-HBED PET/CT showed promising results in staging and restaging of prostate cancer. However, nonspecific uptake has been reported in the celiac ganglia. In this case series, we showed faint radiotracer uptake on upper thoracic region in the location of cervicothoracic (stellate) ganglia. This ganglion is located anterior to the transverse process of C7 vertebra, inferior to subclavian artery, and superior to the neck of the first rib.

This study was undertaken to identify the cause of impotence in men undergoing radical prostatectomy, with the hope that this information may provide insight into the possible prevention of this complication. The autonomic innervation of the corpora cavernosa in the male fetus and newborn was traced to determine the topographical relationship between the pelvic nerve plexus, and the prostate, urethra and urogenital diaphragm. We have demonstrated that the branches of the pelvic plexus that innervate the corpora cavernosa are situated between the rectum and urethra, and penetrate the urogenital diaphragm near or in the muscular wall of the urethra...

Peri-prostatic shunts are frequent during PAE, carrying the risk of non-target embolization of penis/corpus cavernosum or rectum but also the potential advantage to irrigate the contralateral lobe. Sometimes, bilateral embolization is impossible, carrying the risk of limited clinical success. The possibility to reach contralateral prostatic territory from the ipsilateral prostatic artery (PA) and embolize it via peri/intra-prostatic anastomoses could be of interest in this situation. We describe a series of three consecutive patients (among 89 consecutive patients treated by PAE for symptomatic BPH) who underwent successful embolization of both prostatic lobes through catheterization of a PA on only one side...

The growth of disseminated tumor cells into metastatic lesions depends on the establishment of a favorable microenvironment in the stroma of the target organs. Here we show that mice treated with anakinra, an antagonist of the interleukin (IL)-1β receptor (IL-1R), or harboring a targeted deletion of IL-1R are significantly less prone to develop bone tumors when inoculated in the arterial circulation with human prostate cancer (PCa) cells expressing IL-1β. Interestingly, human mesenchymal stem cells exposed in vitro to medium conditioned by IL-1β-expressing cancer cells responded by upregulating S100A4, a marker of cancer-associated fibroblasts (CAFs), and this effect was blocked by anakinra...

OBJECTIVES: To describe the technique of robotic high-extended salvage retroperitoneal and pelvic lymphadenectomy (sRPLND+PLND) for 'node-only' recurrent prostate cancer. MATERIALS AND METHODS: Ten patients underwent robotic sRPLND+PLND (09/2015-03/2016) for 'node-only' recurrent prostate cancer, as identified by carbon-11 acetate PET/CT imaging. Our anatomic template extends from bilateral renal artery/vein cranially up to Cloquet's node caudally, completely excising lymphatic-fatty tissue from aorto-caval and iliac vascular trees; RPLND precedes PLND...

We report a case of nonischemic priapism following brachytherapy. A 63-year-old man presented 22 days after brachytherapy for prostate cancer. He suffered painless sustained incomplete erection for a few days. The patient was diagnosed with nonischemic priapism by cavernosal blood gas analysis. Right internal pudendal arteriography showed blood pooling in the cavernosum caused by arteriovenous fistula. Selective arterial embolization with gelatin sponge particles was performed and detumescence achieved. To our knowledge,this is the first case of high flow priapism caused by brachytherapy for prostate cancer...

REVIEW
Anirudh Mirakhur, Justin P McWilliams
Prostate artery embolization has garnered much attention as a promising treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia. We aim to provide an up-to-date review of this minimally invasive technique, including discussion of potential benefits and technical challenges. Current evidence suggests it is a safe and effective option for patients with medication-refractory urinary obstructive symptoms who are poor surgical candidates or refuse surgical therapy. Larger, randomized studies with long-term follow-up data are needed for this technique to be formally established in the treatment paradigm for benign prostatic hyperplasia...

Shear wave elastography (SWE) is a new non-invasive diagnostic imaging technique, that maps the elastic properties of tissues. Nowadays this modality develops increasingly in medicine across its disciplines and opens a new era of high-quality ultrasound examination because it increases the specificity and thus improves diagnostic assurance. This method is similar to manual palpation, shows elastic properties of biological tissues and provides a kind of reconstruction of the internal structure of soft tissues based on measurement of the response of tissue compression...

BACKGROUND: A few Japanese cases of hypermucoviscous Klebsiella pneumoniae (K. pneumoniae) invasive syndrome have recently been reported. Although extrahepatic complications from bacteremic dissemination have been observed, infected aneurysms are rare. Furthermore, the primary source of infection is generally a liver abscess, and is rarely the prostate. Therefore, we report two atypical cases of hypermucoviscous K. pneumoniae invasive syndrome. CASE PRESENTATION: The first case was an 81-year-old Japanese man with no significant medical history, who was referred to our hospital for vision loss in his right eye...
