Percentage of kidney stone patients who are male?
65-80%
Treatment of small stone
small less than 5mm
typically pass within four weeks of initial symptoms and need no management
Treatment of larger stone:
greater then 5mm
will pass about half the time without further management
Hallmark findings of kidney stone patients:
sudden, sharp, severe pain originating deep in the lumbar area and radiates around the side and down toward the testicle in the male Nausea and vomiting Palpable flank mass Hematuria Fever and chills Urge to urinate frequently Abdominal muscle spasms
Which dermatomes are usually sensitive in kidney stone patients?
T10-L1
Pyelonephritis
inflammation of the renal parenchyma
Chronic Glomerulonephritis
inflammation of the glomeruli of both kidneys
Common types of infection:
pyelonephritis
chronic glomerulonephritis
Less common types of infection:
Renal papillary necrosis
Renal tuberculosis
People at risk for kidney infection:
Age over 60
Hx of diabetes or HTN
Hx of kidney disease, heart attack, or stroke
Hx of kidney stones or UTI
African, Hispanic, Pacific Island, or Native American descent
Exposure to chemicals (e.g. paint, glue, degreasing solvents, cleaning solvents), drugs, or environmental conditions
Low birth weight

Stress Incontinence
Those who engage in anal sex
Structural or congenital abnormalities that obstruct urinary flow (e.g. prostatic hypertrophy or malignancy)
Patient’s who have or have had an indwelling urinary catheter or have experienced urinary tract obstruction
Hallmark finding in kidney infection patients:

Endometriosis:
An estrogen-dependent disorder defined by the presence of endometrial tissue (lining of the
uterus) outside of the normal uterus area
Regurgitation Theory:
Most common theory explaining this disorder is which is also called, retrograde menses, which means the blood goes up into the body, rather than down and out
through the vagina
Metaplastic Theory:
Endometrial tissue arises from endometrial differentiation of coelomic epithelium. During development of the embryo there is no differentiation between reproductive
cell types
Vascular/lymphatic Dissemination Theory:
endometrial cells somehow work their way into the
vascular/lymphatic system
4 Most common areas for endometriosis
to occur:
Surface of the ovaries
Endometrioma: in the ovaries
Peritoneum over the uterus
Fallopian tubes
Incidence of endometriosis may be higher in:
women who have infertility issues (15-70%)
women younger than 20 with chronic pelvic pain (44-73%)
women during reproductive age
