Part 2 is the surgical half. A prostate that keeps growing eventually stops responding to pills — then it's TURP 🔪, a 3-way Foley 🚿, and a set of rules about urine color and irrigation that the NCLEX asks over and over: output must always be MORE than input.
🌰 BPH = benignToo many normal cells — not cancer — squeezing the urethra.
🧪 PSA before DREDraw the blood first — an exam or catheter falsely raises PSA.
🚿 Output > InputWith CBI, drainage must exceed irrigant. Never “equal to” or “less than.”
🩸 Bright red at 24 hr= not expected → contact the HCP immediately.

CAUSE
STEP 1 · THE GLAND THAT GREW
Age plus hormones make a walnut into a lemon — and the urethra is running straight through the middle of it.
🌰 Where the prostate sits — and why size matters so much
The prostate is a walnut-sized gland that sits directly below the bladder and completely encircles the urethra. Its normal job is making fluid for semen. Starting around age 40–50, hormone changes (mainly DHT) make the cells multiply — hyperplasia.
Because the gland is a ring around the pipe, growth goes INWARD and closes the pipe. That single fact explains every symptom, every drug and every surgery on this page.
🧠 “Walnut 🌰 → lemon 🍋 → grapefruit 🍊.” The gland grows through fruit sizes while the hole in the middle shrinks. Picture the fruit and you can rebuild the whole pathophysiology.
⭐ Who gets it — the risk picture
👴 Age is the risk factor — starts around 40–50; roughly half of men by 60 and most men by their 80s have some BPH
🧬 Hormonal shift: aging changes the testosterone-to-DHT balance
👪 Family history · obesity · sedentary life · diabetes
🚫 BPH does NOT cause prostate cancer — but a man can have both, so screening still matters
🧠 Benign ≠ harmless. “Benign” only means not cancer. This benign gland can still shut down a kidney.
⚠️ What makes BPH suddenly become an emergency
💊 Anticholinergics & antihistamines — stop the squeeze
🫗 Decongestants (pseudoephedrine) — tighten the bladder neck
🍺 Alcohol binge · large fluid load at once
🥶 Cold weather · immobility · surgery & anesthesia
💩 Constipation / fecal impaction pressing on the urethra
⏳ Holding urine too long
Acute urinary retention is a urologic emergency — it needs immediate catheterization.
🧠 “Cold pill + cold night + held it too long.” That sentence is the classic ED admission for acute retention in a man with BPH.
🔎
CLUES & LABS
STEP 2 · FIND IT
Two symptom families, one finger exam, and one lab everybody mis-times.
🚿 Obstructive symptoms — the stream
⏳ Hesitancy — can't get started
💨 Weak, intermittent stream · straining
💧 Post-void dribbling
🫗 Feeling of incomplete emptying
🚨 Complete inability to void = acute retention
🧠 Obstructive = the pipe. Everything in this list is about how the urine leaves.
🔁 Irritative symptoms — the bladder
🌙 Nocturia — up multiple times a night; usually the reason they finally come in
🔔 Urgency · frequency
💧 Small voided volumes · overflow incontinence
🔥 Dysuria if a UTI has set in
🧠 Irritative = the tank. The overworked, thickened bladder is twitchy — it complains constantly even though little comes out.
👆 The DRE — digital rectal exam tells BPH from cancer
Smooth & rubbery = benign. Hard & nodular = report it.
🧠 “Rubber ball = benign 🎾. Rock = report 🪨.” Two textures, two totaly different conversations with the provider.
🧪 PSA — prostate specific antigen
PSA is a screening tool, not a diagnosis. It is prostate specific, not cancer specific — BPH itself raises it.
💊 Finasteride lowers PSA by roughly half — the provider mentally doubles the result while the client is on it.
🧠 “Blood before finger.”PSA comes before the Poke. If a question has the nurse doing a DRE and then drawing the PSA, that's the error.
🔬 The rest of the workup
📟 Bladder scan / PVR — how much is left behind
🧪 Urinalysis & culture — rule out UTI/hematuria
🧪 BUN & creatinine — is the obstruction hurting the kidneys?
👀 Watchful waiting is legitimate care for mild symptoms
🧠 Front-load the fluids. Same total volume, drunk earlier in the day = same hydration, far less nocturia.
🔪 When do the pills stop being enough?
🚨 Recurrent acute urinary retention
🦠 Recurrent UTIs · 🪨 bladder stones
🩸 Persistent gross hematuria from the prostate
🧪 Rising creatinine / hydronephrosis
😩 Symptoms intolerable despite maximum medical therapy
📗 HESI: “BPH refractory to treatment with other medications?”✅ Anticipate a TURP.
🧠 “Refractory = resect.” The word refractory in a BPH stem is the exam telling you surgery is next.
🔪
TURP & CBI
STEP 4 · THE SURGICAL HALF
Two surgeries, one catheter with three lumens, and a short list of things you must never do.
🔪 TURP vs prostatectomy — through the pipe or through the belly
After EITHER procedure a 3-way Foley catheter is used for continuous bladder irrigation (CBI). It does two jobs: puts pressure on bleeding tissue and allows urine drainage without clots plugging the catheter.
🧠 “TURP goes THROUGH, prostatectomy CUTS.” T = Through the urethra, no scar. Prostateectomy = -ectomy means cut it out.
🚿 The 3-way Foley & continuous bladder irrigation
🧠 “More out than in, or something's plugged in.” Every CBI question reduces to that rhyme. And the irrigant is not urine — subtract it before you chart output.
🩸 Urine color timeline — the numbers to memorize
📘 Kaplan: “24 hours after TURP the nurse notices bright red urine. First action?”✅ Contact the health care provider immediately — bright red is arterial-looking bleeding, not the expected pink.
📗 HESI: “5 days after prostatectomy the client reports small blood clots. First action?”✅ Advise the client to follow up with the HCP immediately — clots days later are not expected.
🧠 “Red → rosé → clear.” Like wine getting weaker: 0 hr red 🍷 · 24 hr rosé 🌸 · then clear 💧. Going backwards in that sequence is always a call to the provider.
🚨 SEVERE PAIN during continuous bladder irrigation — the classic question
“A client reports SEVERE PAIN with continuous bladder irrigation after a TURP. First nursing action?”
1
🔎 ASSESS the amount & character of urine output — light pink color = BEST
▼
2
🧮 Compare output to input — output must be MORE than input, not “equal to” or “less than”
▼
3
🔗 Check the tubing for kinks, clots and dependent loops; check the bladder for distention
▼
4
🚿 Obstructed? Manually irrigate per order / increase the CBI rate as ordered, then notify the HCP
Why pain matters: severe pain usually means the catheter is plugged with a clot and the bladder is over-distending behind it. Pain is the alarm; obstruction is the fire.
🧠 “Pain = plugged.” Do not reach for the pain med first. Assess the output, do the math, unplug the catheter — the pain resolves when the bladder drains.
❌ The NEVER list after prostate surgery
❌
Never let output be less than (or equal to) input — that is an obstruction until proven otherwise.
❌
Never chart the irrigant as urine output — subtract it first, or you will report a wildly false output.
❌
Never stop the irrigation because the urine looks bloody — bleeding needs MORE flow (per order), not less, or clots will form.
❌
Never take a rectal temperature, give an enema, or insert a rectal suppository — the prostate bed sits right against the rectum and can be made to bleed.
❌
Never release or adjust catheter traction without an order — the taped traction is what tamponades the bleeding.
❌
Never let the client strain — no straining at stool, no heavy lifting (over about 10 lb), no long car rides until the HCP clears them. Stool softeners are standard.
❌
Never medicate severe CBI pain before assessing catheter patency — assessment precedes intervention every single time.
🧠 “Nothing in the rectum, nothing but assessment first.” Two sentences that answer most post-TURP SATA items.
✅ Post-op teaching — what they go home knowing
💧 Fluid intake 2–3 L/day — flushes the bladder and prevents clots (HESI answer)
🦠 Observe for signs of UTI — fever, chills, burning, cloudy foul urine (HESI answer)
💪 Kegel exercises for control after the catheter is removed
💩 Stool softeners; high-fiber diet; no straining
🚫 No heavy lifting, driving or sexual activity until cleared (often 4–6 weeks)
☕ Avoid alcohol & caffeine early — they irritate the bladder
📞 Report bright red bleeding, clots, fever, or inability to void
🧠 “Drink, don't strain, watch for burn.” Three habits cover almost every post-TURP discharge question.
⭐ Two things that are EXPECTED — don't panic
📘 Kaplan: “Third day post-op TURP, the catheter is removed and the client has uncontrolled dribbling after urinating.”✅ Temporary incontinence is EXPECTED following urinary catheter removal — reassure and teach Kegels.
Retrograde ejaculation is also common after TURP: semen goes backward into the bladder, so the urine looks cloudy after sex. It is harmless but affects fertility — tell them before discharge.
🧠 Expected vs emergency.Dribbling and cloudy urine after sex = expected. Bright red urine and no output = emergency. The exam mixes them on purpose.
🚨 TUR syndrome — the classic complication to recognize
If a large volume of hypotonic irrigating fluid is absorbed through the open prostate vessels, the client becomes fluid-overloaded and dilutionally hyponatremic. Modern practice uses isotonic saline with bipolar equipment, which has made this much less common — but it is still classic test content.
🧠 Neuro first Confusion, restlessness, agitation, headache, visual changes, seizures
💓 Vitals Bradycardia + hypertension, nausea/vomiting, respiratory distress from overload
🧪 Serum sodium — normal adult 135–145 mEq/L. A falling sodium plus new confusion after a TURP = report immediately.
🧠 “Water on the brain.” Dilutional hyponatremia is too much water around the cells — so brain cells swell and the earliest signs are neuro, not urinary.

QUICK RECALL
SAY IT OUT LOUD
🌰 Ring around the pipeProstate grows inward → obstruction → residual → AKI
🩸 Red → pink → clear0 hr bloody · 24 hr light pink · 36 hr small clots max
😖 Pain on CBI= assess output & patency FIRST — it's a clot, not just pain
❌ Nothing rectalNo rectal temps, enemas or suppositories after prostate surgery
💧 2–3 L/day+ watch for UTI = the discharge SATA answers
💧 Dribbling after cath removal= EXPECTED · teach Kegels
🎯 Cover & check — 8 rapid-fire questions
Q1: BPH refractory to medication — what do you anticipate?
A TURP — transurethral resection of the prostate.
Q2: What is the expected assessment finding immediately after a TURP?
Bloody urinary drainage. It should lighten to light red/pink by about 24 hours.
Q3: 24 hours after TURP the urine is bright red. First action?
Contact the health care provider immediately.
Q4: Severe pain during continuous bladder irrigation — first nursing action?
Assess the amount and color of urine output and compare output to input. Light pink is the best color; output must be MORE than input. Severe pain usually means a clot is obstructing the catheter.
Q5: The CBI bag has infused 2000 mL and the drainage bag holds 2600 mL. What is the urine output?
600 mL. Total drainage minus irrigant infused. Never chart the irrigant as urine.
Q6: Third day post-op TURP, catheter removed, uncontrolled dribbling. What do you tell the client?
Temporary incontinence is expected following urinary catheter removal. Reassure and teach Kegel exercises.
Q7: Which discharge instructions after prostatectomy? (SATA)
Observe for signs of UTI, and ensure a fluid intake of 2–3 L per day. Also: no straining or heavy lifting, nothing rectal, and report bright red bleeding or clots.
Q8: Why is PSA drawn before the digital rectal exam?
Manipulating the prostate (DRE, catheterization, cystoscopy, ejaculation, biopsy) falsely raises PSA. Blood before finger.
