Prostatectomy Care: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Prostatectomy nursing care focuses on catheter and irrigation management after surgery to remove all or part of the prostate. Continuous bladder irrigation is titrated to keep drainage light pink to clear, and true urine output is calculated by subtracting the irrigant volume infused from the total drained. Bleeding, clot retention, and catheter patency are the main early risks.
Indications and contraindications
Prostatectomy is performed for benign prostatic hyperplasia causing bladder outlet obstruction that has not responded to medication, or for prostate cancer, where the approach ranges from transurethral resection (TURP) for benign disease to radical prostatectomy, open or robotic, for cancer confined to the gland. The choice of technique depends on gland size, whether malignancy is present, and whether nerve-sparing is being attempted to preserve continence and erectile function.
Active untreated urinary tract infection is a contraindication until treated, since operating through infected tissue risks sepsis and poor healing. Uncorrected bleeding disorders and anticoagulant therapy that has not been held per protocol also delay surgery, and severe uncontrolled cardiac or respiratory disease may shift the plan toward a less invasive approach or postponement until the patient is optimised.
Getting the patient ready
Baseline urinary function is documented: whether the patient has been in retention, uses intermittent catheterisation, or has any prior catheter, along with baseline continence and erectile function so postoperative changes can be attributed correctly rather than assumed. A prostate-specific antigen level and imaging results are confirmed in the chart, since these guide the extent of surgery, particularly for radical procedures.
Anticoagulants and antiplatelets are held per the surgical team's timeline, and bowel preparation may be ordered before radical prostatectomy given the proximity of the rectum. Teaching before surgery should cover what to expect from a urinary catheter afterward, that some blood-tinged drainage is expected, and, for radical procedures, realistic expectations around temporary or longer-term continence and erectile changes, so the patient is not alarmed by findings that are a normal part of recovery.
Technique and safety checks
After TURP or open prostatectomy, a three-way catheter is typically placed and continuous bladder irrigation (CBI) is started to keep the bladder flushed of clots that could obstruct the catheter and cause painful bladder distension. The irrigation rate is titrated against the appearance of the drainage: it is increased when output turns red or contains clots, and slowed once it settles to a light pink or clear colour. This is a nursing judgement made at the bedside repeatedly through the shift, not a single rate set and left unchanged.
Because irrigant fluid enters the bladder and drains out mixed with urine, true urine output cannot be read directly off the drainage bag. The nurse subtracts the volume of irrigant instilled from the total volume drained to get actual urine output, and this calculation is repeated at every documentation interval. Getting this wrong in either direction can mask oliguria or falsely suggest fluid overload, so the running totals for irrigant in and total out are tracked separately, not combined.
What can go wrong
Clot retention is the complication CBI exists to prevent, and it presents as sudden reduced or stopped drainage, bladder spasms, and suprapubic pain despite irrigation running. Bladder irrigation is manually flushed with a syringe if ordered, and if patency cannot be restored, the surgical team is notified rather than left to increase the automatic rate alone. Significant, persistently bright red drainage or a falling haemoglobin points to arterial bleeding at the surgical bed and needs prompt escalation.
TURP syndrome, caused by absorption of hypotonic irrigating fluid into the venous sinuses opened during resection, produces confusion, hypertension followed by hypotension, bradycardia, and visual disturbance from dilutional hyponatraemia; it is now less common with isotonic irrigants but still needs to be recognised. After radical prostatectomy, watch for urine leak around the catheter suggesting anastomotic breakdown, and for signs of infection or pelvic haematoma. Catheter blockage from clots, and bladder spasms treated with antispasmodics, are common and generally manageable rather than emergencies on their own.
Ongoing care
Once bleeding settles and irrigation stops, catheter care shifts to maintaining patency, preventing infection, and monitoring for continued clear drainage before removal. Pain from bladder spasms is treated with prescribed antispasmodics and reassurance that spasms around the catheter are expected rather than a sign something is wrong.
After catheter removal, the patient is monitored for their first voids, checking for retention, dribbling, or continued haematuria, and pelvic floor exercises are taught early to support the return of continence, particularly after radical prostatectomy. Patients are also given clear guidance on avoiding straining, heavy lifting, and constipation while the surgical site heals, since increased intra-abdominal pressure can provoke bleeding or disrupt healing tissue.
Common exam questions
A frequent scenario describes a patient on CBI whose drainage suddenly turns bright red with clots and stops flowing, and asks for the priority nursing action, which is to check for and relieve catheter obstruction, often by manual irrigation, then notify the surgeon if patency is not restored. Another gives irrigant-in and total-out volumes and asks the test-taker to calculate true urine output, which requires subtracting the irrigant volume from the total drainage.
Questions also test recognition of TURP syndrome from a cluster of neurological and cardiovascular changes in a patient who has had a transurethral resection with hypotonic irrigation, and recognition that persistent bladder spasms with a patent catheter are expected and managed with antispasmodics rather than treated as an emergency.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our med-surg practice questions are the closest set to what this page covers.
One question from the med-surg set
A client with chronic obstructive pulmonary disease has an oxygen saturation of 88% on 2 L/min via nasal cannula and is alert with no distress. What should the nurse do first?
Rationale
In COPD a saturation of 88–92% is the therapeutic target, not an emergency, and this client is alert with no distress. The first action is the independent nursing intervention that is least invasive and most likely to help: sit them up and reassess. Turning the oxygen up to 6 L/min risks blunting the hypoxic drive, and calling rapid response or drawing an ABG escalates ahead of an assessment you have not finished.
Answer: B
Common questions
Why does continuous bladder irrigation need to be titrated?
The rate is adjusted against the colour of the returning drainage: sped up when it is bright red or clotted to flush clots before they obstruct the catheter, and slowed once it turns light pink or clear. Running it at a fixed rate regardless of drainage colour risks either unresolved clot retention or unnecessary bladder distension.
How do you calculate true urine output during CBI?
Subtract the total volume of irrigant fluid infused from the total volume drained from the catheter bag over the same period. The remainder is the patient's actual urine output, which is what should be recorded and trended for fluid balance.
What does clot retention after prostatectomy look like?
Drainage slows or stops despite irrigation running, and the patient develops suprapubic pain and bladder spasms from a distending bladder. It is managed with manual bladder irrigation via syringe to dislodge the clot, escalating to the surgical team if patency is not restored.
Is some blood in the urine normal after a TURP?
Yes, light pink or blood-tinged drainage is expected for the first day or two as the resection site heals, and this is why irrigation is used to keep it flowing rather than allowing clots to form. Persistent bright red drainage or a falling haemoglobin is not expected and should be reported.
What is TURP syndrome and why does it matter for nursing care?
TURP syndrome results from absorption of hypotonic irrigating fluid into the bloodstream during resection, causing dilutional hyponatraemia with confusion, blood pressure changes, bradycardia, and visual disturbance. Nurses monitor for these signs during and shortly after TURP, particularly in longer procedures, since isotonic irrigants have reduced but not eliminated the risk.
