Optimizing penile length in patients undergoing partial penectomy for penile cancer: novel application of the ventral phalloplasty oncoplastic technique.

J. Wallen; Adam S. Baumgarten; Tim Kim; Tariq S. Hakky; Rafael Carrion; Philippe E. Spiess

The ventral phalloplasty (VP) has been well described in modern day penile prosthesis surgery. The main objectives of this maneuver are to increase perceived length and patient satisfaction and to counteract the natural 1-2 cm average loss in length when performing implantation of an inflatable penile prosthesis. Similarly, this video represents a new adaptation for partial penectomy patients. One can only hope that the addition of the VP for partial penectomy patients with good erectile function will increase their quality of life. The patient in this video is a 56-year-old male who presented with a 4.0x3.5x1.0 cm, pathologic stage T2 squamous cell carcinoma of the glans penis. After partial penectomy with VP and inguinal lymph node dissection, pathological specimen revealed negative margins, 3/5 right superficial nodes and 1/5 left superficial nodes positive for malignancy. The patient has been recommended post-operative systemic chemotherapy (with external beam radiotherapy) based on the multiple node positivity and presence of extranodal extension. The patients pre-operative penile length was 9.5 cm, and after partial penectomy with VP, penile length is 7 cm.

Advances in Surgical Reconstructive Techniques in the Management of Penile, Urethral, and Scrotal Cancer

Michael Bickell; J. Beilan; J. Wallen; Lucas R. Wiegand; Rafael Carrion

This article reviews the most up-to-date surgical treatment options for the reconstructive management of patients with penile, urethral, and scrotal cancer. Each organ system is examined individually. Techniques and discussion for penile cancer reconstruction include Mohs surgery, glans resurfacing, partial and total glansectomy, and phalloplasty. Included in the penile cancer reconstruction section is the use of penile prosthesis in phalloplasty patients after penectomy, tissue engineering in phallic regeneration, and penile transplantation. Reconstruction following treatment of primary urethral carcinoma and current techniques for scrotal cancer reconstruction using split-thickness skin grafts and flaps are described.

Deflate-gate: Conservative Management of a Large Ruptured Hydrocele

Viktor X. Flores; J. Wallen; Danny R. Martinez; Rafael Carrion

A hydrocele is a common cause of intrascrotal swelling that results when fluid accumulates between the parietal and visceral layers of the tunica vaginalis. Over time, fluid may collect to form a massive hydrocele and result in significant discomfort for the patient. In this case report, we present a rare event of a 28-year-old gentleman with a documented massive hydrocele measuring 14.1 × 8.9 cm who ruptured his hydrocele during sexual intercourse. We expectantly managed the patients ruptured hydrocele and encountered no complications throughout the course of his recovery.
