The good, the bad, and the ugly about surgical approaches for inflatable penile prosthesis implantation
https://pubmed.ncbi.nlm.nih.gov/32488210/The good of the Penoscrotal approach(1)
Excellent exposure of both proximal and distal corpora cavernosa even for patients with obesity or corporal fibrosis
(2)
Little risk of injury to dorsal neurovascular bundle
(3)
Pump placement is facilitated
(4)
The small scrotal incision leaves negligible scar
(5)
One incision double implant of IPP and artificial urinary sphincter is possible
The bad of the Penoscrotal approach(1)
Blind placement of the reservoir into the space of Retzius.
(2)
Scrotal swelling can delay device activation
(3)
Risk of injury of scrotal urethra; the urethra is easily seen and can be repaired
The ugly of the Penoscrotal approach(1)
None. There is no irreversible complication with PS incision
The good of the Infra Pubic approach(1)
Easier, safer reservoir placement under direct vision
(2)
Diminished scrotal swelling resulting quicker pump activation
(3)
Shorter operative time in skilled hands
(4)
Incision is remote from patients with incontinence and allows abdominoplasty.
The bad of the Infra Pubic approach(1)
Limited visualization of distal corpora cavernosa
(2)
Pump placement is not optimal with the risk of pump migration
(3)
Severe obesity and fibrotic corpora are challenging
(4)
Revision surgery after the IP approach, if required, is associated with increased difficulty and worse surgical outcomes
(5)
Scar of IP incision is visible
The ugly of the Infra Pubic approach(1)
Risk of dorsal nerve injury, a complication from which there is no cure. While a paper in 2018 claimed that there were no reports of this complication in the literature, both Drs. Scott and Wilson sustained one in the 1980s. Wilson has also been an expert witness in six additional cases sustained with IP (all successful) that came to litigation in USA. Decreased penile sensation occurs most often following revision cases when the anatomy is not so clear.
