Ultrasound findings of ruptured Peyronie's plaque: Case report and review of the literature

We present here a rare case of rupture of tunica albuginea and corpus cavernosum, in the site of a Peyronie's plaque, which happened in a 61- year-old man during a vacuum cleaner masturbation. Ultrasound study showed an irregular hyperechoic defect at the cavernosal rupture site in correspondence of the Peyronie's plaque. The hematoma was evacuated, partially plaque excised, and the tear repaired. Ultrasonography is an ideal technique for evaluating patients with penile trauma and can be routinely used in an emergency. It is a non-invasive method that gives faster results than cavernosography and Magnetic Resonance Imaging

Prostatic fiducial markers implantation by transrectal ultrasound for adaptive image guided radiotherapy in localized cancer: 7-years experience

Objective: we present our 7-years' experience with fiducial gold markers inserted before Image-Guided Radiotherapy (IGRT) focusing on our echo-guided technique reporting early and late complications. Material and methods: 78 prostate cancer (PCA) patients who underwent fiducial markers placement for adaptive IGRT (period 2007-2014) were selected. Mean patient age was 75 years (range 60-81), mean PSA 7.8 ng/ml (range 3.1-10), clinical stage < T3, mean Gleason Score 6.4 (range 6-7). We recorded early and late complications. Maximum distance between the Clinical Target Volume (CTV) and Planning Target Volume (PTV) was assessed for each direction and the mean PTV reduction was estimated. Results: we describe in details our echo-guided technique of intraprostatic gold fiducial markers insertion prior to adaptative IGRT. We report rare early toxicity (5-7% grade 1-2), a mean PTV reduction of 37% and a very low late toxicity (only 3.4% bladder G3 and 8% rectal G2 side effects). Conclusion: Our technique of fiducial gold markers implantation for adaptative IGRT is safe and well-tolerated and it resulted helpful to reduce CTV-PTV margin in all cases; the effects on clinical practice seem significant in terms of late toxicity but further investigations are needed with longer follow-up

MRI/US fusion prostate biopsy: Our initial experience

Aim: The objective of this study is to present our initial experience with magnetic resonance imaging/ultrasound (MRI/US) fusion biopsy using the Koelis Trinity device after the first consecutive 59 patients. Materials and methods: 59 consecutive patients with suspected prostate cancer (PCA) underwent prostate biopsy using Trinity Koelis® (Koelis, Grenoble, France). We divided the patients into 2 groups: patients with a previous negative mapping underwent to a MRI/US fusion re-biopsy (Group A); and biopsy-naïve patients who underwent to a first stereotactic 3-D mapping of the prostate (Group B). Group A (22 patients):mean age 64 years (CI 48-73), mean PSA = 7.7 ng/ml (CI 4.2- 9.9); mean prostate volume 55 ml(CI 45-82), Digital Rectal Examination (DRE) positive in 2/22, number of lesions detected by MRI 1.4, mean cores from each MRI target lesion 3 (CI 2-5), mean total cores 15 ( CI 12-19). Group B (37 patients): mean age 66 years (CI 49-77), mean PSA= 4.7 (3.2- 7.9); mean prostate volume 45 ml (33-67), DRE positive in 5/37, mean total cores 14 ( CI 10-16) Results: In Group A 10/22 patients were positive for PCA (overall detection rate of 45.5%): 6 PCA were detected by target biopsy and 4 cancer by random biopsy. Significant prostate cancer (defined as the presence of Gleason pattern 4) was detected in 4/10 patients (Significant PCA detection rate of 40%) and all significant PCA were detected by MRI target biopsy. All PCA detected by random biopsy had Gleason score 3 + 3 = 6. In Group B (biopsy naïve patients) 14/37 patients were positive for PCA (overall detection rate of 37.8%), Significant prostate cancer was detected in 5/14 patients (Significant PCA detection rate of 35,7%). No significant side effects were recorded. Conclusions: Our overall detection rate was 45.5% and 37.8% in Group A (patients with previous negative biopsy and persistent suspicion of PCA) and in Group B (biopsy naïve patients) respectively; clinical significant PCA detection rate was respectively 40% and 35.7%. These results are similar to current literature and promising for the future. We believe that using platforms of co-registered MRI/US fusion biopsy can potentially improve risk stratification and reduces understaging, undergrading and the need for repeat biopsies in biopsy naïve patients (using a stereotactic first mapping) and in patients with previous negative biopsy and persistent suspicion of PCA ( using a second MRI/US fusion biopsy)

Practical recommendations for performing ultrasound scanning in the urological and andrological fields

Aim: US scanning has been defined as the urologist's stethoscope. These recommendations have been drawn up with the aim of ensuring minimum standards of excellence for ultrasound imaging in urological and andrological practice. A series of essential recommendations are made, to be followed during ultrasound investigations in kidney, prostate, bladder, scrotal and penile diseases. Methods: Members of the Imaging Working Group of the Italian Society of Urology (SIU) in collaboration with the Italian Society of Ultrasound in Urology, Andrology and Nephrology (SIEUN) identified expert Urologists, Andrologists, Nephrologists and Radiologists. The recommendations are based on review of the literature, previously published recommendations, books and the opinions of the experts. The final document was reviewed by national experts, including members of the Italian Society of Radiology. Results: Recommendations are listed in 5 chapters, focused on: kidney, bladder, prostate and seminal vesicles, scrotum and testis, penis, including penile echo-doppler. In each chapter clear definitions are made of: indications, technological standards of the devices, the method of performance of the investigation. The findings to be reported are described and discussed, and examples of final reports for each organ are included. In the tables, the ultrasound features of the principal male uro-genital diseases are summarized. Diagnostic accuracy and second level investigations are considered. Conclusions: Ultrasound is an integral part of the diagnosis and follow-up of diseases of the urinary system and male genitals in patients of all ages, in both the hospital and outpatient setting. These recommendations are dedicated to enhancing communication and evidence-based medicine in an inter- and multi-disciplinary approach. The ability to perform and interpret ultrasound imaging correctly has become an integral part of clinical practice in uro-andrology, but intra and inter-observer variability is a well known limitation. These recommendations will help to improve reliability and reproducibility in uro-andrological ultrasound scanning

Catheter-associated urinary infections and consequences of using coated versus non-coated urethral catheters-outcomes of a systematic review and meta-analysis of randomized trials

Coated urethral catheters were introduced in clinical practice to reduce the risk of catheter-acquired urinary tract infection (CAUTI). We aimed to systematically review the incidence of CAUTI and adverse effects in randomized clinical trials of patients requiring indwelling bladder catheterization by comparing coated vs. non-coated catheters. This review was performed according to the 2020 PRISMA framework. The incidence of CAUTI and catheter-related adverse events was evaluated using the Cochran-Mantel-Haenszel method with a random-effects model and reported as the risk ratio (RR), 95% CI, and p-values. Significance was set at p 14 days) (RR 0.82 95% CI 0.68-0.99, p = 0.04). There was no difference between the two groups in the incidence of the need for catheter exchange or the incidence of lower urinary tract symptoms after catheter removal. The benefit of coated catheters in reducing CAUTI risk among patients requiring long-term catheterization should be balanced against the increased direct costs to health care systems when compared to non-coated catheters

Sonographic patterns of Peyronie's disease in patients with absence of palpable plaques

ABSTRACT Purpose Non-palpable isolated septal plaques of the penis are likely present in a significant number of patients affected by erectile dysfunction (ED) and penile pain without deformity or curvature. The aim of this study was to evaluate the ultrasound (US) patterns observed in patients investigated for ED or penile pain without curvature. Materials and Methods We reviewed the medical records of 386 patients who underwent an initial colour-Doppler ultrasonography (CDU) of the penis for DE and/or penile pain without curvature. After satisfying inclusion criteria, 41 patients were individualized. All patients had a non-palpable plaque with involvement of the penile septum. Three US patterns were identified: focal hyperecoic thickening of the intercavernosum septum (IS) with acoustic shadow (pattern 1), non-calcified thickening (isoechoic or slightly hyperechoic (pattern 2), and microcalcifications in the IS without associated acoustic shadow (pattern 3). Results Patients’ mean age was 51.3±16.7. ED was the predominant disorder in 73.2% of patients, followed by penile pain and length loss in 19.5% and 7.3% of patients, respectively. 32(78.1%) patients showed the pattern 1, 6 (14.6%) pattern 2, and 3 (7.3%) pattern 3. Plaques size varied from 3 to 13 mm. The penile hemodynamic response to CDU reported abnormal findings distally to the septal plaques in 20 patients (<25cm/sec). Median left and right cavernosum artery flows measured a peak systolic velocity of 31cm/sec and 33 cm/sec, respectively. Conclusions We believe that an US study with CDU provides a way to characterize, localize, and deliver treatment choice in patients with Peyronie's Disease
