Objective: Shear wave elastosonography (SWE) could be used to evaluate the elasticity of penile tissue. Few studies in the literature, however, have investigated its use in patients with erectile dysfunction (ED) or have attempted to correlate findings with International Index of Erectile Function (IIEF-5) scores. The primary aim of this study was to evaluate the characteristics of erectile tissue using SWE and to determine possible relationships with IIEF-5 and Erection Hardness Scale (EHS) scores. The secondary aim was to establish a cut-off SWE examination value over which cavernous tissue stiffness could contribute to a subsequent organic alteration. Methods: This prospective study included male patients 18−80 years of age who attended two general andrology clinics and underwent SWE. Subjects were divided into groups according to IIEF-5 score, and correlations between SWE and IIEF-5 and EHS questionnaire scores were explored. Results: A total of 270 subjects (mean age 46.7 ± 16.9 years) were included. ED was reflected by low IIEF-5 and EHS scores and a decrease in the mean elasticity of the corpora cavernosa according to SWE, although the difference between the left and right corpora cavernosa was not statistically significant. No statistically significant correlation was found between measurements of the corpora cavernosa (in kPa) and age. The optimal cut-off identified was 24.75 kPa. Conclusion: Results demonstrated that the mean elasticity of the corpora cavernosa according to SWE was correlated with IIEF-5 score and EHS score.
Background: Peyonie's disease (PD) mostly affects males in the fifth decade of life, with a prevalence in the general population ranging between 0.5% and 20.3%. The pathology of PD is characterized by fibrosis of the tunic albuginea of the cavernous bodies of the penis, with the presence of pain in the erection and penile deformity. This is associated with decreased sexual function for both participants. The objective of the study was to investigate the influence of PD pathology on both male patients' and their female partners' sexual spheres, and analyze changes in sexual function and perception following penile correction surgery.Methods: Prospective study, we included male patients with PD and their female partner sexually active.Patients underwent corporoplasty with multiple plications. The male and female sexuality was evaluated before surgery and three months after male treatment by the Female sexual Function Index (FSFI); International Index of Erectile Function (IIEF); Visual Analogical Scale (VAS).Results: From January 2018 to November 2019 we included 35 couple. The female subjects before partner's surgery presented dyspareunia, loss of sexual desire, inability to achieve orgasm, and sexual dissatisfaction. At three months after surgical treatment there was an improvement of sexual function in both male patients and female partners (desire P<0.0001, arousal P<0.0001, lubrification P<0.0001, orgasm P<0.0001, satisfaction P<0.0001, pain P<0.0001). As regarding male patients the pain decreased significantly (VAS score from 6 to 2.5), while there was no statistically significant improvement in erectile function (P=0.05).Conclusions: Our findings suggest that a viable approach to treatment of PD patients that involves their partners could lead to better functional and psychological results.
Purpose The primary objective of this study was to evaluate the testicular stiffness by ultrasound shear wave elastography (SWE) both in men with oligo-astheno-teratozospermia (OAT) and in control group. The secondary objective was to identify a possible correlation between semen quality with testicular stiffness. Methods This was a prospective case-control study. We divided the sample in two groups; Group A (case group) included men with OAT, and Group B (control group) men with normal sperm parameters. All participants had at last two semen analysis in the past 180 days (at last 90 days apart), using performed ultrasound and SWE elastography. Results We analyzed 100 participants, 50 patients in Group A and 50 controls in Group B. There were statistically significant differences in term of testicular volume and testicular stiffness between two groups. Men with OAT had the testicular stiffness value higher than the controls in both sides (left testicular stiffness 21.4 ± 5.4 kPa vs 9.9 ± 1.6 kPa, p < 0.0001; right testicular stiffness 22.9 ± 4.8 kPa vs 9.5 ± 2.4 kPa, p < 0.0001). Men with abnormal semen parameters showed an inverse correlation between the mean value of testicular stiffness and total sperm count (22.15 ± 3.38 kPa, r = − 0.387, p = 0.005), sperm concentration (22.15 ± 3.38 kPa, r = − 0.244, p = 0.04), and progressive motility (22.15 ± 3.38 kPa, r = − 0.336, p = 0.01), while the correlation was not evident in controls group. Conclusion SWE is able to differentiate between testicles with spermatogenic changes from a healthy testicle. For this reason, it could be used to evaluate, in a non-invasive way, the tissue alterations of the organ.
Several diagnostic techniques have been proposed during the time for the diagnostic evaluation of Induratio Penis Plastica (IPP), due to poor sensitivity and specificity of standard B-Mode Ultrasonography. Shear-Wave elastosonography (SWE) is a relative new ultrasound technique, already used for several organs, which allows evaluating the rigidity of the tissues. Furthermore, we used a compound consisting of Ecklonia bicyclis, Tribulus terrestris, and Biovis (water-soluble Chitosan) with antifibrotic and antioxidant properties and analyzed the elastosonographic variations following the assumption of the compound. From March 2016 to April 2017, 40 patients were recruited with a mean age of 62. All patients underwent elastosonographic measurements at the start of treatment. Subsequently each patient took 1 tablet of the compound of Ecklonia bicyclis, Tribulus terrestris, and Biovis (water-soluble Chitosan) for 6 months. All patients underwent elastosonographic investigation at the end of treatment. The elastosonographic measurement prior treatment, showed that the average of the three measurements (proximal, medial and distal), was 37.05 KPa ± 7.76 SD and 38.8 KPa ± 10.11 SD for the left and right cavernous body, respectively. The examination at the end of the six months of treatment, with the compound showed that the average values of fibrosity were 31.07 KPa ± 7.5 SD and 30.86 KPa ± 11.4 SD for the left and right cavernous body respectively, demonstrating a decrease in fibrosity that was statistically significant (P < 0.01). Our data demonstrate that taking the compound for six months reduces the stiffness of the corpora cavernosa.
