Reproductive system disorders Flashcards
What is benign prostatic hyperplasia?
Prostate gland enlargement. The prostate grows and compresses on the urethra (which passes through the prostate) causing urinary symptoms.
What causes Benign Prostatic Hyperplasia?
It isn’t entirely clear what causes the prostate to enlarge. However, it might be due to changes in the balance of sex hormones as men grow older.
What are the risk factors for Benign Prostatic Hyperplasia?
Aging- Prostate gland enlargement rarely causes signs and symptoms in men younger than age 40. About one-third of men experience moderate to severe symptoms by age 60, and about half do so by age 80.
Family history - Having a blood relative, such as a father or a brother, with prostate problems means you’re more likely to have problems.
Diabetes and heart disease - Studies show that diabetes, as well as heart disease and use of beta blockers, might increase the risk of BPH.
Lifestyle - Obesity increases the risk of BPH, while exercise can lower your risk.
What are the symptoms of Benign Prostatic Hyperplasia?
Frequent or urgent need to urinate
Increased frequency of urination at night (nocturia)
Difficulty starting urination
Weak urine stream or a stream that stops and starts
Dribbling at the end of urination
Inability to completely empty the bladder
Less common signs and symptoms include:
Urinary tract infection
Inability to urinate
Blood in the urine
What are the possible complications of Benign Prostatic Hyperplasia?
Acute urinary retention - May require catheterisation or surgery
UTIs -Inability to fully empty the bladder can increase the risk of infection, recurrent UTIs with BPH may require surgery to have part of the prostate removed
Bladder stones - These are generally caused by an inability to completely empty the bladder. Bladder stones can cause infection, bladder irritation, blood in the urine and obstruction of urine flow.
Bladder damage - A bladder that hasn’t emptied completely can stretch and weaken over time. As a result, the muscular wall of the bladder no longer contracts properly, making it harder to fully empty your bladder.
Kidney damage - Pressure in the bladder from urinary retention can directly damage the kidneys or allow bladder infections to reach the kidneys.
Most men with an enlarged prostate don’t develop these complications. However, acute urinary retention and kidney damage can be serious health threats.
Why might patients with Benign Prostatic Hyperplasia be encouraged to limit caffeine and alcohol?
They can increase urine production, irritate the bladder and worsen symptoms.
Why might patients with Benign Prostatic Hyperplasia be encouraged to limit decongestants or antihistamines?
These drugs tighten the band of muscles around the urethra that control urine flow, making it harder to urinate.
What are the main treatments for Benign Prostatic Hyperplasia?
Medication
- Alpha blockers e.g. Tamsulosin
- H-alpha reductase inhibitors e.g. Finasteride
Surgery
Catheterisation
Symptom control
-Lifestyle changes
-Techniques for urination
How do alpha blockers treat BPH?
These medications relax the muscle of the prostate and bladder neck, which allows urine to flow more easily
What are 5-ARIs and how do they treat benign prostatic hyperplasia?
5-Alpha Reductase Inhibitors
Both normal and abnormal prostate growth is driven by the androgen dihydrotestosterone (DHT), which is formed from testosterone under the influence of 5-alpha reductase. Thus, 5-alpha reductase inhibitors (5-ARIs) effectively reduce the serum and intraprostatic concentration of DHT, causing an involution of prostate tissue.
What is chlamydia?
Chlamydia trachomatis bacterial infection
What are the symptoms and complications of chlamydia?
Often has few and/or mild symptoms:
-Painful urination
-Vaginal discharge
-Discharge from the penis
-Painful sexual intercourse in women
-Vaginal bleeding between periods and after sex
-Testicular pain
-Conjuntivitis/pneumonia in neonates
Complications include:
In women
-Pelvic Inflammatory Disease
-Risk of transmission to baby if pregnant
In men:
-Can affect fertility.
-Epididymitis
-Reactive arthritis (SARA - sexually acquired reactive
arthritis) joints/eyes or urethra become inflamed, usually within the first few weeks after having chlamydia (can affect women but more common in men)
What is gonorrhea?
A bacterial infection that can infect the cervix, urethra, rectum, throat and eyes.
What are the symptoms of gonorrhea?
Dysuria and discharge (thick, greenish/yellow/cream). Intermenstrual bleeding.
Pelvic inflammatory disease and infertility in women
Prostatitis and epididymitis in men.
Both sexes may develop reactive arthritis.
Neonates may have conjunctivitis.
Women are often asymptomatic
What are the complications of gonorrhea?
Verticle transmission from mother to baby, neonate may develop permanent blindness if untreated.
Miscarriage and premature labour in women.
Infertility in men and women.
