Q

First line MEDICAL therapy for urge incontinence

A

Antimuscarinics: (Tolterodine, Oxybutynin). These are anticholinergics and antispasmodics that increase bladder capacity

Q

Other medical options for urge incontinence

A

Mirabegron: beta-3 agonist that causes bladder relaxation

TCA: Imipramine (antispasmodic, increased urethral sphincter tone)

Surgical: Botox injection, bladder augmentation

Q

How to management bladder atony in overflow incontinence (if associated with a neurological disorder)

A

Intermittent or indwelling catheterization is first-line
-Cholinergics (Bethanechol) increases detrusor muscle activity

16
Q

What are the two common etiologies of stress incontinence?

A

Laxity of pelvic floor muscles: childbirth, surgery, postmenopausal estrogen loss

Urethral hyper mobility: insufficient support from pelvic floor musculature

17
Q

Symptoms of stress incontinence

A

Urine leakage during times of increased intra-abdominal pressure (coughing, laughing, sneezing, lifting heavy objects)

No urge to urinate prior to leakage

18
Q

Initial treatment of choice for stress incontinence

A

Pelvic floor (Kegel) exercises + Lifestyle modifications (weight loss, smoking cessation, protective garment pads, drink smaller amounts of water throughout the day)

19
Q

What is another option for conservative treatment for stress incontinence

A

Pessaries
-used if no response to lifestyle modifications and Kegel exercises

20
Q

What surgical option exists for stress incontinence

A

Midurethral sling (more rapid and definitive than conservative therapy)

21
Q

What is peyronie disease?

A

Abnormal localized fibrotic changes of the tunica albuginea leading to abnormal penile curvature

22
Q

What layer is fibrotic in peyronie disease?

A

Tunica albuginea

23
Q

Symptoms of peyronie disease

A

-Penile pain
-Curvature
-Induration
-Shortening
-Sexual dysfunction

24
Q

What is the treatment for peyronie disease if the curvature is less than 30 degrees?

A

Observation. Urologist referral.

25
However, if the curvature is greater than 30' in peyronie disease, what is the treatment?
Oral Pentoxifylline if within 3 months of onset Intralesional injection with collagenase if > 3 months
26
What is the MC risk factor for uterine prolapse?
Weakness of pelvic support structures (MC after childbirth) -Other times: lifting heavy objects, multiple vaginal births, loss of estrogen (post menopause)
27
Symptoms of uterine prolapse
vaginal fullness Low back pain, abdominal pain Symptoms worse with prolonged standing Urgency, frequency, stress incontinence
28
Explain the grading scale of uterine prolapse. There are grades 0-4.
Grade 0: no descent Grade 1: uterus descent into upper 2/3 of the vagina Grade 2: cervix approaches the introitus Grade 3: cervix outside the introitus Grade 4: entire uterus is outside the vagina - complete rupture
29
What are some mechanical treatments for uterine prolapse?
Pessaries elevate and support the uterus. Estrogen treatment may improve atrophy.
30
However, the surgical management for uterine prolapse includes
Hysterectomy or sacrospinous ligament fixation
31
What is vesicoureteral reflux?
Retrograde passage of urine from the bladder into the upper urinary tract
32
What is the MC type of vesicoureteral reflux and why does it occur?
Primary VUR -Due to inadequate closure of or incompetent ureterovesical junction that contains a segment of the ureter within the bladder wall.
33
What is often the initial imaging ordered for VUR?
Renal and bladder US
34
However, the diagnostic imaging of choice for VUR is?
Voiding cystourethrogram (or radionuclide cystogram)
35
If the VUR presents postnatal, what does it usually look like?
Febrile UTI
36
Treatment for Grade I and II VUR
Observation and ABX Prophylaxis (Bactrim, Trimethoprim, or Nitrofurantoin)
37
Treatment for Grade III and IV VUR
Surgical correction is the definitive treatment
