Q

Is urinary incontinence a normal part of aging?

A
  • Incontinence isn’t a “normal part of aging” but is more prevalent in the older adult
  • Some changes in the urinary tract as we age can contribute: (1) bladder capacity, (2) contractility and (3) ability to postpone voiding can decline as wel age
  • Some things may enlarge (such as prostate)

Q

What questions do you ask to determine the patient is incontinent?

A
  1. Ask about the onset of incontinence and for a description of the incontinence pattern.
  2. Obtain a description of normal urinary pattern and fluid intake. Inquire about other urinary problems, such as hesitancy, frequency, urgency, nocturia, dysuria, and decreased force or interruption of the urine stream.
  3. Ask about a history of urinary tract infection (UTI), prostate conditions, spinal injury or tumor, stroke, COPD, chronic cough, diabetes, obesity, or surgery involving the bladder, prostate, or pelvic floor.
  4. Ask a female patient about the number of pregnancies and childbirths.
  5. Ask about smoking, alcohol, and caffeine use.
  6. Obtain a complete drug history.

What is oliguria?

A

Oliguria is a medical term for low urine output (how much you pee). In the case of an adult, this means less than 400 milliliters (mL) to 500 mL (around two cups) of urine per 24 hours. The numbers depend on weight in terms of children and infants.

Q

What is pyuria?

A

Pyuria is a condition defined by the increased presence of white blood cells in urine. Although a urinary tract infection is the most common cause of sterile pyuria, other conditions may be involved. the presence of 10 white blood cells in each millimeter cube of the urine. Sterile pyuria, in contrast, is a type of pyuria in which no bacteria are present in the urine. This could be due to a medical condition, non-detected bacteria, or another germ, such as a virus.

36
Q

What is a renal cell carcinoma?

A

Renal cell carcinoma is a malignant neoplasm of the kidney; it comprises several distinct morphologic types, some of which are familial

Patients may be symptomatic (eg, hematuria, flank pain), but very often the lesion is found incidentally on imaging for unrelated reasons

Treatment of localized disease is primarily surgical. Nephron-sparing treatment (partial nephrectomy) is favored for stage I and, when feasible, for stages II and III; radical nephrectomy is recommended for surgical candidates with large or complex tumors

Thermal ablation is an option for smaller lesions in patients who cannot undergo surgery; active surveillance without immediate intervention is also an option for selected patients with small lesions (stage I, less than 2 cm 1)

37

42
Q

What is Transurethral resection of the prostate (TURP)

A

Transurethral resection of the prostate (TURP) is a surgery used to treat urinary problems that are caused by an enlarged prostate.

An instrument called a resectoscope is inserted through the tip of your penis and into the tube that carries urine from your bladder (urethra). The resectoscope helps your doctor see and trim away excess prostate tissue that’s blocking urine flow.

TURP is generally considered an option for men who have moderate to severe urinary problems that haven’t responded to medication. While TURP has been considered the most effective treatment for an enlarged prostate, a number of other, minimally invasive procedures are becoming more effective. These procedures generally cause fewer complications and have a quicker recovery period than TURP.

43
Q

What does management look like after TURP?

A
  • Monitor urinary drainage and keep catheter patent
  • Assessment of pain
  • Bladder spasms cause feelings of pressure and fullness, urgency to void, and bleeding from the urethra around the catheter.
  • Medication and warm compresses or sitz baths to relieve spasms
  • Administer analgesics and antispasmodics as needed
  • Encourage patient to walk, but to avoid sitting for prolonged periods.
  • Prevent constipation
  • Irrigate catheter as prescribed
44
Q

What is CBI?

A

often done after TURP

Continuous bladder irrigation (CBI) is a medical procedure that flushes your bladder with a sterile liquid. It also removes urine (pee) from your body at the same time. Healthcare providers often use it to prevent or remove blood clots after surgery on the urinary system. The procedure takes place in a hospital over several days.

45
Q

What is pt teaching about BPH and after TURP?

A

—Diet low in fat and red meat, high in protein and vegetables

—Adequate hydration; avoid drinking too much fluid in a short period.

—Avoid alcohol, diuretics, caffeine, artificial sweeteners, spicy or acidic foods.

—Avoid medications that cause urinary retention – antihistamines, decongestants, anti-cholinergic, anti-depressants

—Post-TURP teaching:

◦Normal to feel the urge to void while the catheter is in place.

◦Do not void around the catheter to avoid bladder spasms.

◦Urine will be blood-tinged, can pass small clots for several days – increase fluid intake to at least 2-2.5 L daily (unless contraindicated).

◦Monitor for infection and incontinence.

◦Reproduction ability should not be affected.

◦Report severe spasm and decreased urinary output → possible obstruction

—Signs and symptoms of acute urinary retention

46
Q

What is erectile dysfunction?

A

—Inability to achieve or maintain an erection for sexual intercourse.

—May be organic (gradual deterioration of function) or functional (rapid onset, usually have normal nighttime and morning erections, follows a period of high stress).

—Has a strong correlation with hypertension and BPH and spinal issues

—Medications- most common intervention for ED ▪ Phosphodiesterase-5 inhibitors (PDE-5) – relaxes the smooth muscle in corpora cavernosa –box) table 67.4 page 1488

47
Q

What are the three ways that erectile dysfunction can be managed?

A
  1. Pharmacologic agents
    1. oral meds (sildenafil)
      1. side effects: HA, flushing, dyspepsia
      2. Caution with retinopathy
      3. contraindicated with nitrate use
    2. Injected vasoactive agents
      1. Complications include priapism (persistent abnormal erection)
    3. urethral suppository
  2. Penile implants
  3. Negative pressure devices - vacuum
