- For mod-advanced pelvic organ prolapse (cystocele, rectocele, enterocele, uterine prolapse, vaginal eversion) → refer to urologist of gynecologist specializing in urinary incontinence and pelvic organ prolapse repair
25
Stress Incontinence

RULE OUT of secondary causes is done by ordering:
- syphilis tests (only if high clinical suspicion based sexual hx or travel)
- vit B12 deficiency
- TSH
** Refer all pts w/ suspected Alzheimer's ds and PD to neurologist for diagnostic evaluation and management!
