Medications (What is taken, what may affect UO/micturation/renal toxicity)
What is an important bit of information to teach elderly patients about their renal function
to drink plenty of water everyday even if they are not thirsty as it is good for their renal function
What information should we gather about renal system pain patterns
Is the pain from distention, obstruction, or inflammation of renal tissue?
Are we discovering these diagnoses when they seek care for other symptoms?
Are they experiencing any pain even?
Is absence of pain or symptoms for issues lik STIs common

24 hour urine collection
How does a 24 hour urine collection work
A special orange speciment container with a preservative is obtained from the lab in order to collect urine (unless the pt has an indwelling catheter)
Signs are posted in the client room, chat, and bathroom regarding all urine needing to be collected in the next 24 hours
Client will void and discard the first urination at the start of the 24 hour period and then begin collecting everything after that
Once 24 hours is up container is put on ice and the client should void one last time to collect that urine before being sent to the lab

Ablation
Perineal
Retropubic
Why is screening for DRE and PSA important
because if DRE is abnormal of PRE is high it could mean prostate cancer
however, diagnosis requires confirmation via biopsy
Which prostate surgical procedure requires no incisions
TURP - Transurethral resection
Technically ablation too
Suprapubic Prostatectomy
There is an incision in the ambdomen AND bladder to access the prostate
Longer recovery process and monitoring for blood/hemorrhaging is important
Perineal Prostate Surgery
incision between scrotum and anus to get to prostate gland
can lead to impotence, sexual dysfunction, or rectal damage
Retropubic Prostate Surgery
AVOIDS BLADDER INCISION
Incision in abdomen while avoiding the bladder
Increased infection risk
Important Prostate Surgery PreOp and PostOp Nursing Diagnoses
PreOp:
Anxiety
Acute Pain
Deficient Knowledge
Post Op:
Risk for imbalanced fluid volume
Acute pain
Deficient knowledge about post op care
Transurethral Incision
Similar results to TURP but has an incision made (1-2 to relieve pressure on the urethra itself)
Transurethral Resection (TURP)
Prostatic tissue is removed through the urethra by optical instruments
Used for glands of various sizes and ideal for those who are at surgical risk
Advantages of TURP
avoids abdominal incision
safer for surgical risk pateints
shorter length of stay in hospital and recovery periods
lower morbidity rates
causes less pain
can be used as a palliative approach with hx of radiation therapy
Disadvantages of TURP
requires a highly skilled surgeon
recurrent obstruction, urethral trauma, and strictures can develop
delayed bleeding can occur
Important Nursing Consideration Post Op with TURP
monitor for hemorrhage
observe for symptoms or urethral stricture such as dysuria, straining, weak urinary stream
CBI - cont. bladder irradiation
give antispasmodics
Nursing Dx for Prostate Cancer
Anxiety
Urinary Retention
Deficient Knowledge
Imbalanced Nutrition: Less than body requirements
Sexual dysfunction
Acute pain
Impaired physical mobility
Hemorrhage, infection, bladder neck obstruction
Important Nursing Considerations Post Op with Suprapubic Surgery
abdominal and bladder incision needs frequent dressing changes - 2 incisions were made
longer healing process
sterility needs and issues
Important nursing considerations post op with retropubic surgery
less bleeding than most others
drainage and bladder spasms occur - need to monitor
Collaborative Problems/Potential Complications from any prostate surgery
hemorrhage and shock
infection
VTE/DVT
catheter obstruction
complications with catheter removal
urinary incontinence
sexual dysfunction
Nursing Interventions Post TURP
Assess for bleeding
Assess and treat pain
Infection
DVT Prevention/prophylaxis - get them walking ASAP
Obstruction monitoring
Antispasmodics as prescribed
Teach exercises for sphincter control
Continuous Bladder Irrigation (CBI)
What bleeding may be normal at first following TURP
Bleeding should be red/pink for 24 hours after and then turn a more tea like color
but if color remains bright red or has clots in it, then it is abnormal bleeding and indicates arterial bleeding - contact the provider
Continuous Bladder Irrigation
a 3 way (lumen) irrigation system to decrease bleeding and keep the bladder free from clots
Its a bag putting fluid into the stomach and it continuously allows bladder irrigation to prevent clot buildup and keep things moving
What is one major potential complication that can occur from CBI
TURP Syndrome
TURP Syndrome
A syndrome caused by CBI caused by neurologic, lyte, and cardiac imbalance from too much absorption of the irrigated fluid
S/S of TURP Syndrome
HTN
NV
Confusion
Cardiac Issues
What should be done if you suspect TURP syndrome
stop CBI and let the provider know
What are the 3 lumens on CBI used for
1 is for inflating a balloon (30 mL) to hold it in place
1 is for outflow
and 1 is for instillation (inflow)
How much fluid should be given to Post Op TURP Patients
2400-3000 mL/d if possible
When can you begin ambulating a post op TURP patient
ASAP - so as soon as the urine is more clear (not when pink/red)
What does arterial bleeding appear like post TURP and what should be done if this occurs
bright red urine with numerous clots –> If this occurs increase CBI and notify physicial immediately
What does venous bleeding appear like Post TURP and what should be done if this occurs
burgundy colored UO –> If this occurs inform MD who may apply traction on catheter
Important rule to CBI
What is put in must come out - so what is instilled better be in bag outflow or else something is wrong like tube kinking, urinary retention etc which can cause overdistention leading to secondary hemorrhage
Catheter Traction
Maintaining tautness to the catheter (straight leg not bent) taped to the abd/thigh which is done by the MD
Never released without MD order - usually after bright red/burgundy colored drainage diminished
Important to Post TURP Care
What should be run through the CBI
Normal Saline (or glycine) to prevent water intoxication
At what rate should CBI be run
at a rate to keep the urine pink
If bright red or has clots than run it faster (40 gtt/minute once bright red clears)
What should be done if the CBI catheter is obstructed
Turn off CBI, irrigate catheter with 30-50 mL NS and notify MD if obstruction is unresolved
What two things are important to watch for when using CBI / post TURP
Turp Syndrome
Severe Hyponatremia (Water intoxication)
(Both caused by excessive CBI absorption)
Important TURP Post Op Care Considerations
Expect red-light pink urine 24 hours - then amber for 3 days
Continuous feelings of urge to void is normal
Avoid attempts to void around catheter - causes bladder spasms
Antibitoics, Analgesics, Stool Softeners, and AntiSpasmodics as prescriped
Monitor 3 way foley cath: 30-45 mL retention balloon
Maintain CBI with NS
Educate on post op diet, s/s to watch for
Control pain
Stress importance of doctor follow up
