Repair of the penile suspensory ligament for congenital and acquired pathology

Abstract

Objective: To review the mechanisms and patient outcomes for men presenting with abnormalities of the penile suspensory ligament (PSL) and their correction.

Patients and methods: We conducted a retrospective review of a total of 118 patients who presented with a variety of PSL abnormalities that necessitated surgical repair from 1993 to 2018. The patients mean (range) age at presentation was 29 (12-60) years with a mean (range) follow up of 8 months (3 months-12 years). The diagnosis was made clinically, often with a history of penile instability, pain or curvature/torsion, which was confirmed on artificial erection testing. Nocturnal tumescent testing and magnetic resonance imaging were used where necessary. The surgical repair was performed by placing non-absorbable sutures between the tunica albuginea of the penis and the symphysis pubis. Postoperative outcomes were reported in the clinic by direct questioning and a repeat of the investigations above when patients were unsatisfied with the result.

Results: The aetiologies and surgical indications in the 118 patients included: abnormality subsequent to sexual trauma (n = 66); congenital curvature of penis and/or congenital absence/laxity of the ligament (n = 37); Peyronie's disease (n = 8); and venogenic erectile dysfunction (ED; n = 7). A good surgical result, as defined by stabilization and straightening of the penis and a return to normal sexual function, was achieved in 85% of the patients and 82% were very satisfied with the outcome. Complications included long-term ED in four patients.

Conclusion: Abnormalities of the PSL are uncommon and often subtle, but with the appropriate diagnosis, a good cosmetic and functional result is usually achievable.
