Difficulties in achieving vs maintaining erection: organic, psychogenic and relational determinants

Achieving and maintaining a penile erection are two essential components of the male sexual response. It has recently been suggested that distinct molecular mechanism could underlie the two disturbances. The aim of the present study is to verify possible clinical differences on pathogenetic factors underlying difficulties of achieving and maintaining an erection. We studied a consecutive series of 560 patients (aged 51.9712.8 y old) reporting erectile dysfunction (ED), using SIEDY r structured interview. Patients were classified into two distinct categories: those with difficulties in maintaining, rather than achieving, an erection (sample A) and those with main problems in achieving an erection (sample B). A complete physical examination and a series of metabolic, biochemical, hormonal, psychometric, penile vascular tests and nocturnal penile tumescence and rigidity evaluations (NPT) were also performed. Sample B patients showed a higher prevalence of organic conditions related to ED, when compared with sample A as confirmed by higher SIEDY r scale 1 scores (3[1-5] vs 1[0.1-3] for sample B vs sample A, respectively; Po0.0001) which explores organic component of ED and higher prevalence of pathological instrumental parameters. No difference among groups was observed for SIEDY r scale 2 (relational component) and SIEDY r scale 3 (intrapsychic component) of ED. In conclusion, this study shows for the first time that patients with difficulties in maintaining erection are less likely to be affected by organic disturbances interfering with sexual function, when compared with those unable to achieve a valid erection.

“…However, a discontinuity of the echogenic line representing albuginea tear is important, as surgery is usually needed [17]. Associated vascular injuries can be shown by CD techniques [20]. If an arterial lesion is present, a post-traumatic arteriovenous fistula with increased venous pressures and dilatations of the injured vessel may result [20,21].…”

If an arterial lesion is present, a post-traumatic arteriovenous fistula with increased venous pressures and dilatations of the injured vessel may result [20,21]. In literature, studies on the diagnosis of penile fracture through CD ultrasonography, reported as a valuable diagnostic tool, are limited in number [21].…”

Purpose In this prospective study, we studied the role of ultrasonography (US) in the diagnosis and management of penile trauma. Methods Between 2007 and 2014, 14 patients (mean age 39 years) with suspected penile fracture underwent US examinations. Almost all patients had a history of injury during sexual intercourse or manipulation of the penis. US examinations were performed in transversal and longitudinal planes starting at the level of the glans and moving down to the base of the penis. Color-Doppler was used to identify the vascular pattern or to see any abnormal vascularity. Results The most common blunt injury to the penis that occurred in nine patients was penile fracture due to rupture of the corpus cavernosum. A tear occurred in only one of the corpora cavernosa. US showed an irregular hypoechoic or hyperechoic defect at the cavernosal rupture site. Four patients presented an injury to the subtunical venous plexus in the absence of complete tunical disruption. One patient had urethral rupture with inability to urinate and apparent urethrorrhagia. Ten patients underwent surgical operation, while four patients were observed and discharged after 2 days. Mean follow-up was 32 months (range 3-58). After 8 to 12 weeks, all of them were able to be sexually active as before. Angulations of penis persisted in one patient. Conclusion US may be the preferred imaging technique for evaluation of penile fracture before surgery. It is easy to perform, non-invasive, widely available, and inexpensive, although it requires an experienced team.Keywords Penile trauma Á Penile fracture Á Ultrasonography Á Color-Doppler sonography Á Imaging Á Tunica albuginea Riassunto Scopo In questo studio prospettico abbiamo analizzato il ruolo dell'imaging ecografico nella diagnosi e gestione del trauma penieno. Metodi Tra il 2007 ed il 2014, 14 pazienti (età media: 39 anni) con sospetto di frattura del pene furono sottoposti ad uno studio ecografico. Quasi tutti i pazienti presentavano un riscontro anamnestico di traumi avvenuti durante un rapporto sessuale o manipolazione del pene. Gli esami ecografici furono eseguiti facendo scansioni su piani trasversali e longitudinali iniziando a livello del glande e procedendo sino alla base dell'asta. L'utilizzo del ColorDoppler è stato adoperato per visualizzare l'assetto vascolare o per identificare qualsiasi forma di anomalia vascolare. Risultati La più comune forma di rottura traumatica del pene accorsa in 9 persone fu quella del corpo cavernoso. la rottura si verificò sempre a livello di un singolo corpo cavernoso. Lo studio ultrasonografico identificò il punto di rottura a livello del corpo cavernoso attraverso la visualizzazione di un irregolare stria ipoecogena o iperecogena. 4 pazienti presentarono una lesione del plesso venoso al di sotto della tunica albuginea senza rottura della stessa. Un solo paziente riportò un trauma dell'uretra presentando difficoltà alla minzione ed uretrorragia. 10 pazienti furono sottoposti ad intervento chirurgico, mentre gli altri 4 furono ricovera...

EF was categorized as follows using the IIEF-5 total scores: no ED (22)(23)(24)(25), mild ED (17-21), mild to moderate ED (12)(13)(14)(15)(16), moderate ED (8-11) and severe ED (5-7). 19,20 Presence and severity of painful erections was determined on a conventional 10-point visual analog pain scale (VAS) score ranging from 0 to 10, with 0 being no pain and 10 being severe pain.…”
