Surgical or conservative treatment of penile fracture

Abstract

Introduction: Penile fracture presents with rupture of corpora cavernosa. It is not rare but is remarkable. Treatment options are controversial. Aim: To establish the incidence, what are early and late complications in patients treated surgically or with conservative treatment options (prospective/retrospective and randomized analysis). To find out what therapy verified as superior. Material and method: The total of 32 patients with typical acute penile fracture were analyzed. The patients were between 20 and 56 years of age (Mean age 40+7.25 SD). A total of 11 patients that presented up to 48h after the rupture of tunica albuginea (34.37%) were operated, while 9 patients (28.13%) were conservatively treated. 12 patients (37.5%) reported to andrology consulting room due to penile fibrous alterations and/or erectile dysfunction 6 to 14 months after the anamnesticaly established, typical penile fracture ("primary latent penile fracture"). Both groups of patients were strictly clinically followed 3, 6, 9 and 12 months after the penile fracture. Eventual development of late complications (erectile dysfunction ED, penile curvature, induratio, caverno-urethral fistula and urethral stenosis) was also recorded. Etiology of ED was investigated: anamnesticaly, by hormone and laboratory analysis, using penodynamic test (PGE1), Duplex Doppler echosonography, and dynamic cavernosography. Results: In the operated group of patients, (11 pts, 34.37%) preserved erectile capacity was recorded and no penile deformity or plaque lesions on the site of suture, after the patients were recommended to have 4 weeks of sexual abstinence. The rupture of tunica albuginea was always transversal in relation to penile axis i.e. in relation to axial force against which the penis acts during the intercourse. The rupture is always on the basis or mid penile portion . Out of 21 (65.63%) conservatively treated patients in 13 (61.9%) plaque lesions (longitudinal diameter 2 cm) was recorded, while sexual dysfunction was established in 13 patients (12 with ED and 1 patient with incapability for vaginal penetration). Evaluation of post therapeutical complications in relation to type of treatment, significantly higher frequency was recorded in the group of conservatively treated patients (p<0.01). Penile veno-oclusive dysfunction was registrated as significantly most frequent cause of ED (in 10 - 76.92% out of 13 patients). All patients with ED had palpable fibrous lesion similar to Peyrone?s plaque, while the degree of penile deviation correlated to the size of plaque lesion. Conclusion: The late complications of penile fracture were significantly more frequently recorded in the group of conservative treated patients (p< 0.01) which proves that this lesion presents as urgent urological entity. The penile rupture is always transversal, and most probable place of rupture is physiological penile curve since this is the site of weakened structural integrity.
