preplace sutures to disperse tension so they don’t immediately tear out.
Use simple interrupted all the way around to create a new urethral exit

Describe Scott’s technique for phallectomy

Answer 15

you use a circumferential incision to cut around the urethra, not into it.

After that, you dissect a portion free.

Than, using simple interrupted absorbable suture (because the area is highly vascularized) you close the corpus cavernosum and the sinuosoidal space.
