Phallectomy is the surgical removal of part or all of the penis. It is indicated for malignant diseases, traumatic injury, irreparable injury, or permanent paralysis. The procedure involves catheterization of the urethra and application of tourniquets before transecting the penis using techniques like the Williams technique or Vinsot technique. Post-operative care includes fluid therapy, antibiotics, anti-inflammatories, and daily antiseptic use. Complications can include bleeding, hemorrhage, dehiscence, pain, infection, edema, and stricture formation.

2. Phallectomy
• Synonyms: Penile amputation, Penectomy, Peotomy
• Surgical removal of a part of penis or penis(whole organ)
or
• Phallectomy is the surgical removal of the distal extremity of the penis, but
the organ remains in the preputial cavity.

3. Indications
• Malignant Diseases (when neoplasia has invaded the tunica albuginea or is
so extensive that more conservative treatment by cryosurgery,
hyperthermia, local excision is impossible.)
• Traumatic Injury
• Irreparable Injury
• Permanent Paralysis
• Urethral stenosis (distal aspect)

4. Anatomy of Penis
 Three major parts of penis
root (radix penis)
body (corpus penis)
glans (glands penis)
 Functionally triad of structures (three columns of erectile tissue)
Two corpora cavernosa penis (CCP; cavernous bodies)
One corpus spongiosum penis (CSP; spongy body)

5. Conti……
 Muscle of the penis
Paired striated
• Ischiocavernosus
• Bulbocavernosus (bulbospongiosus)
Paired smooth
• Retractor penis
Urethralis muscle
 Blood Vessels
• Arteries supplying the penis include
• the terminal branches of the internal
pudendal (or internal pudic),
• obturator, and
• external pudendal (or external pudic)
arteries
• Veins are external pudic, perineal and
internal pudic vessels

6. Anesthesia
• General Anesthesia
• Dorsal or drso-ventral recumbency
• Ketamine (Ketarol®) @ 4mg/kg
• Diazepam (Diazepam ®, Valium ®) @ 0.02-0.4 mg/kg
• Ketamine : Diazepam (6 ml:4 ml)

7. Techniques
•Williums Technique
•Vinsot Technique
•Scott Technique

8. Williums Technique
The Glans penis is hooked out of the sheath by the tip of index finger
introduced into Navicular fossa (Urethral sinus).
A catheter is introduced into urethra and one tourniquet is applied about
at the base of penis and one posterior to level of amputation.
Triangular urethrostomy is made on the ventral portion of the penis
removing the skin, bulbospongiosus muscle and CSP.
The triangle is oriented so the apex point proximally and base of the
triangle is the site of penile transection.

9. Williums Technique
The urethra is split on its midline from the base to the apex of the triangle,
and the edges of the urethra and the triangle’s epithelial edges are
apposed with simple-interrupted absorbable sutures.
After that transect the glans penis circumferentially in gradual way and
apposed the sheath or skin with muscular part at the same time by
interrupted suture.
At the end part of penis is removed and last suture is placed.
Remove the tourniquet which was tied at proximal part (base).

19. Post operative care
• Fluid therapy
• Antibiotic therapy for 5 to 7 days
• Anti-inflammatory therapy for 5 days
• Transamine injection (avoid hemorrhages or bleeding)
• Prophylactic dose of ATT
• Daily Use of Antiseptic Agent

20. Complications
• Bleeding (during surgery….be calm…..no nervousness)
• Hemorrhage from the penile stump, especially at the end of urination,
should be expected for at least several days after Phallectomy.
• Dehiscence of sutured erectile tissue may lead to the formation of a large
hematoma.
• Other complications of phallectomy in the immediate postoperative period
include pain, infection of the surgical wound, edema of the prepuce, and
acute urinary obstruction caused by edema of the urethra.

21. Complications
• Long-term complications include cystitis, dysuria caused by urethral
stricture, recurrence of neoplasia at the site of amputation, and neoplastic
metastases to inguinal lymph nodes and internal organs.
