Double distal corporal anchoring stitch for lateral penile implant cylinder extrusion.

Abstract

Background: The ventral and distal aspects of the corpora cavernosa are the thinnest, increasing the likelihood of cylinder extrusion or crossover complications pertaining to inflatable penile prosthesis procedures. A double distal corporal anchoring double stitch can be used to robustly secure impending lateral extrusions and crossovers of implant cylinders. It is a novel, effective corrective measure for the uncommon complication of migrated cylinders in inflatable penile prosthesis placement.

Aim: To describe the surgical indications and technique for the double distal corporal anchoring fixation stitch for lateral penile implant cylinder extrusion.

Methods: We discuss a double-stitch technique that is performed following corporoplasty and capsulotomy. A lateral incision is made subcoronally on the affected side to identify the crossover or lateral extrusion. The cylinder is repositioned properly within the native corpora to prevent further cylinder migration. Two 2-0 Ethibond sutures are threaded through the distal cylinder eyelet, and each suture is delivered through the glans with a Keith needle and tied off. An incision is made in the glans, and 1 arm of each suture is tied with the other to create a bridge between the sutures that can be positioned deep within the skin of the glans.

Outcomes: Over the past 4 years, 66 patients with lateral cylinder extrusion underwent the double distal corporal anchoring fixation stitch procedure, with overall improved satisfaction (97%). Only 2 patients had surgical complications. One patient experienced repeated lateral extrusion of the penile implant cylinders 6 weeks following the double-anchoring stitches procedure. The second patient developed a painful suture granuloma that necessitated excision, which resolved this issue, and the penile implant cylinder remained in the proper position over a year later.

Clinical implications: This technique ensures the secure fixation of the affected cylinders in the surgical capsule by creating a bridge between 2 sutures holding each repositioned cylinder in place, and the ensuing fibrotic reaction helps to fixate the extruded cylinder within the midglandular tissue.

Strength and limitations: This surgical technique describes the double distal corporal anchoring stitch for lateral penile implant cylinder extrusion. Further studies are warranted to validate long-term outcomes and satisfaction.

Conclusion: The double distal corporal anchoring fixation stitch is a safe and efficacious method to secure cylinders in the proper surgical capsule during revision procedures to correct distal crossovers or laterally extruded penile prosthesis implants.
