Q

Initial evaluation of patient with suspected Peyronie’s includes:

A

GUIDELINE STATEMENT 1

document signs and symptoms - characterize

history to assess deformity, interference with intercourse, pain, distress, frequency of sexual activity/changes

PE - for palpable nodules and curvature (often need to stretch), tenderness, DRE, scrotal exam, fibrosis/plaque

Q

Treatment with extracorporeal shock wave therapy (ESWT) for PD is indicated for:

A

GUIDELINE STATEMENT 14/15

for pain

NOT

reduction in curvature or plaque size

17
Q

In the presence of stable PD, clinicians should assess patients as candidates for what?

A

GUIDELINE STATEMENT 17

surgical reconstruction

12-18m after onset, stable curvature 3-6 mo

in stable dz, pain only with erection

establish:
location (proximal, mid, distal)
direction of curvature (dorsal, lateral, ventral)
degree of curvature
presence of other deformities (indentation, hinge, narrowing, hourglass, shortening, uniplanar, biplanar)
presence, location, extent of plaque (calcification)
presence and extent of ED
interference with intercourse for patient/partner
degree of distress

18
Q

What surgical options are appropriate for adequate rigidity (w or w/o meds and VED) for improving penile curvature?

A

GUIDELINE STATEMENT 18

tunical plication

GUIDELINE STATEMENT

plaque incision or excision and/or grafting

19
Q

Risks and a/e of tunical plication surgery:

A

urethral laceration
urinary retention
UTI
superficial skin necrosis (minor/major)
hematoma (obs vs. re-operation)
wound infection
chest infection
painful/palpable suture
suture granuloma
phimosis
ED or penile pain (persistent)

20
Q

What surgery may be offered to patients with PD and ED and/or significant penile deformity?

A

GUIDELINE STATEMENT 20

IPP

when deformity sufficient to impair coitus despite meds and/or VED

GUIDELINE STATEMENT 21

may perform adjunctive intra-operative procedures such as. modeling, plication, or incision/grafting when significant deformity persists after insertion of IPP

modeling/maneuvers when >30 after IPP

GUIDELINES STATEMENT 22

should use IPP

21
Q

Grafting techniques are indicated when penile curvature is:

A

>60 degrees, hourglass deformity, or penile shortening

22
Q

What type of grafts can be used in PD surgery?

A

autologous (vein, dermis, buccal) → increased morbidity

non-autologous (trend towards tissue engineered, pericardium, small intestine, or collagen fleece → no sutures required)

23
Q

Peyronie’s Algorithm

A
24
Q

How does intralesional interferon alpha-2b work?

A

cytokine thought to inhibit fibroblasts

works for curvature, pain, plaque

stable dz, curvature > 30 without calcified plaque

25
Q

How does intralesional collagenase clostridium histolyticum in combination with modeling work?

A

stable curvature > 30 < 90

break down plaque and model to straighten

can improve 35-75%

(not for hourglass, calcified or ventral plaques or acute dz)

26
Q

types of penile plication:

A
  1. excising and ellipse (Nesbit)
  2. vertical incision closed horizontally (Yachia)
  3. dot technique that imbricates tunica
  4. graft (incise/excise at point of m ax curvature), repair tunica with graft
27
Q

Important questions to ask patient presenting with suspected PD?

A

direction of curvature
presence of UI
presence of pain w or w/o erection
current ability to have intercourse
degree of ED
stability curvature
presence of pain with intercourse for patient or partners
hx of intercourse injury

28
Q

What are risks of IPP when done for PD?

A

pain
infection
need for ectopic placement of reservoir if after RP
adjacent organ injury
need for additional surgery
device erosion
device malfunction
residual curvature
decreased sensation
loss of penile length and girth
bleeding

29
Q

Critical steps of modeling?

A

assure not injury to urethra or corpora
cycling device and repeating as necessary
applying force opposite the point of max curvature for 90 seconds
mark point of max curvature
protecting pump with rubber shods
completely inflating IPP prior to modeling
