“…Since injury to the erectile tissue or the tunica albuginea may affect the venoocclusive mechanism and result in venogenic impotence, measurements of EDV and its derivative, RI, have been proposed as valid parameters for identifying patients with veno-occlusive dysfunction. 18,21 There was a clear relationship between RI and length of stricture in the present study, where patients with shorter urethral stricture had better RI, indicating better erectile function. From the present study, it seems that the major physiological change in patients with urethral stricture is venoocclusive, and that the incidence of erectile dysfunction may increase with the length of the stricture.…”

This study evaluated dynamic colour duplex Doppler ultrasound (D-CDDU) for the assessment of erectile function in patients with post-traumatic urethral stricture. In total, 44 patients with urethral stricture secondary to trauma were recruited between January 2009 and June 2010. Peak systolic velocity of the cavernosal artery was measured before and after intracavernosal injection (ICI) of 20 mg papaverine and 1 mg phentolamine. Cavernosal artery end-diastolic velocity and resistance index (RI) were evaluated after ICI. Patients with RI ≥ 0.8 had significantly shorter strictures than those with RI < 0.8 after ICI only in cases of posterior urethral stricture. Patients with RI ≥ 0.8 were significantly younger than those with RI < 0.8. Urethral stricture length was negatively correlated with RI (r = -0.375). Cavernosal artery RI after ICI is a reliable predictor of erectile function in patients with urethral stricture, especially posterior stricture. The patient's age should be considered when using this parameter.

Introduction The field of erectile dysfunction (ED) is evolving and there is a need for state-of-the-art information in the area of treatment. Aim To develop an evidence-based, state-of-the-art consensus report on the treatment of erectile dysfunction by implants, mechanical devices, and vascular surgery. Methods To provide state-of-the-art knowledge concerning treatment of erectile dysfunction by implant, mechanical device, and vascular surgery, representing the opinions of 7 experts from 5 countries developed in a consensus process over a 2-year period. Main Outcome Measure Expert opinion was based on the grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate. Results The inflatable penile prosthesis (IPP) is indicated for the treatment of organic erectile dysfunction after failure or rejection of other treatment options. Comparisons between the IPP and other forms of ED therapy generally reveal a higher satisfaction rate in men with ED who chose the prosthesis. Organic ED responds well to vacuum erection device (VED) therapy, especially among men with a suboptimal response to intracavernosal pharmacotherapy. After radical prostatectomy, VED therapy combined with phosphodiesterase type 5 therapy improved sexual satisfaction in patients dissatisfied with VED alone. Penile revascularization surgery seems most successful in young men with absence of venous leakage and isolated stenosis of the internal pudendal artery following perineal or pelvic trauma. Currently, surgery to limit venous leakage is not recommended. Conclusions It is important for the future of the field that patients be made aware of all treatment options for erectile dysfunction in order to make an informed decision. The treating physician should be aware of the patient’s medical and sexual history in helping to guide the decision. More research is needed in the area of revascularization surgery, in particular, venous outflow surgery.

“…12 In such traumas, the loss of the veno-occlusive mechanism or injury to the cavernosal artery can occur after tunica rupture in the corpus cavernosum during penile fractures, causing the development of ED. 13 We also know that in surgeries for penile curvature, Nesbit corporoplasty with tunica excision leads to higher ED rates compared with the 16-dot plication technique without excision. 14 The fact that higher ED rates are observed in corporoplasties, even in tunica defects that are created in a controlled manner and repaired immediately, suggests that ED after penile fracture may be related to the length of uncontrolled tunica rupture.…”

The role of preoperative ultrasound in the diagnosis of penile fractures and the effect of tunica defect length on postoperative functional outcomes

Penile fractures are caused by rotational or bending trauma to the penile shaft during erection, and they generally present with unilateral ruptures of the tunica albuginea around the corpus cavernosum with or without urethral injury. 1 The main reasons for penile fractures listed in the literature are sexual intercourse, bending the erect penis to achieve sudden detumescence during masturbation (the taghaandan manoeuvre) and accidentally rolling over in bed onto the erect penis. 2 Although the site of the injury is variable, it occurs mostly in the midshaft region or near the base of the shaft. 3 Patients usually describe a cracking sound, followed by pain and rapidly occurring haematoma. 4 Blood at
