Acute urinary retention or infection cannot wait for a routine TURP appointment
Seek Urgent Medical Care If
- You have a painful, increasingly full lower abdomen and cannot pass urine.
- You have fever, chills, confusion or feel markedly unwell with urinary symptoms or a catheter.
- You pass heavy blood, large clots or very little urine despite a painful urge or catheter.
- You develop severe flank pain, vomiting, faintness or rapidly worsening weakness.
The immediate priorities are safe drainage, infection control, bleeding assessment and kidney protection. TURP is planned only after the patient is stable and the cause and anatomy are adequately assessed.
What Is TURP?
The prostate surrounds the first part of the urethra below the bladder. Benign enlargement commonly affects the central transition zone, compressing the urinary channel. TURP removes part of this obstructing tissue from inside the channel and leaves a cavity through which urine can flow more freely.
A resectoscope combines a telescope, irrigation system and movable electrical loop. The surgeon removes small tissue chips, controls bleeding and evacuates the chips from the bladder. The outer prostate and capsule remain in place.
TURP cores out a channel—it is not a radical prostatectomy
A radical prostatectomy removes the entire prostate as cancer treatment. TURP usually treats benign obstruction by removing central tissue. Prostate tissue, PSA production and the possibility of future prostate disease therefore remain after TURP.
When May TURP Be Recommended?
Troublesome voiding symptoms
A persistently weak, hesitant or intermittent stream and incomplete emptying may justify surgery when obstruction is confirmed and other treatment is insufficient or unsuitable.
Repeated or persistent retention
Men who cannot urinate without a catheter may need definitive outlet treatment when prostate obstruction is the cause.
Recurrent infection or bladder stones
Poor emptying caused by the prostate can contribute to infection and stone formation.
Recurrent prostate-related bleeding
Persistent visible bleeding attributed to benign prostate enlargement may support intervention after other causes have been evaluated.
Upper-tract or kidney effects
Back-pressure or kidney impairment related to bladder-outlet obstruction can make treatment more urgent.
Patient preference
Some men choose an established procedural option after comparing durability, recovery, ejaculation and other alternatives.
Which Prostates Are Commonly Suitable?
TURP is an established standard surgical option for bothersome moderate-to-severe symptoms caused by benign prostate obstruction, commonly when prostate volume is approximately 30–80 mL. This is a planning range, not an absolute rule.
A small prostate without a large middle lobe may be better suited to an incision rather than tissue resection. A very large gland may be treated more efficiently with enucleation or simple prostatectomy. Surgeon experience, instrument size, operating time, anatomy and the individual patient can shift these boundaries.
TURP Is Not Automatically Prostate-Cancer Surgery
Benign prostate enlargement and prostate cancer are different conditions, although they can coexist. A benign TURP is intended to improve urine flow; it does not remove the whole prostate or reliably treat cancer elsewhere in the gland.
Removed tissue is sent for histopathology and can occasionally reveal unsuspected cancer. That finding requires its own PSA, imaging, staging and treatment discussion. A normal TURP specimen cannot guarantee that no cancer exists in unsampled prostate tissue.
When Might Another Approach Be Better?
- Observation or non-surgical treatment may be appropriate when symptoms are mild and complications are absent.
- A transurethral prostate incision may suit selected smaller glands without an obstructing middle lobe.
- Enucleation or simple prostatectomy may remove large-volume obstructing tissue more efficiently in very large glands.
- Vaporisation, implant, thermal or vascular approaches may offer different balances of bleeding, catheter time, ejaculation, durability and reoperation.
- Long-term catheter drainage may be appropriate when surgery or anaesthesia is unsuitable, although it has its own risks.
- Weak bladder contraction, urethral narrowing, neurological disease or predominant storage symptoms may require a different or additional plan.
No procedure is best for every man. Treatment choice should match the actual cause of symptoms rather than prostate size alone.
How Is the TURP Decision Made?
What Happens Before TURP?
- Clinical assessment: Symptoms, their severity, quality-of-life impact, examination, catheter history and previous urinary procedures are reviewed.
- Urine assessment: Urine dipstick, microscopy or urine culture checks for infection before endoscopic surgery.
- Flow and emptying assessment: Uroflowmetry and post-void residual are commonly used when the patient can urinate.
- Prostate and urinary-tract imaging: Ultrasound estimates prostate volume, residual urine, bladder changes and upper-tract effects.
- Selected tests: PSA, cystoscopy, urethral imaging or urodynamics may be appropriate when the result will change management.
- Blood tests: Kidney function, blood count, electrolytes and clotting assessment may be required.
- Regular-treatment review: Bring a complete list. Never stop blood-thinning or other regular treatment without a written plan from the responsible clinicians.
- Anaesthesia and fasting: Complete the required assessment and follow the hospital’s exact fasting instructions.
- Consent: Discuss alternatives, catheterization, bleeding, ejaculation, continence, incomplete relief, pathology and retreatment.
What Happens During TURP?
Monopolar and Bipolar TURP
Both techniques use an electrical resection loop and provide comparable improvement in urinary symptoms and flow. The main technical difference is the electrical circuit and irrigation fluid.
Monopolar TURP
Electrical current travels from the loop through the patient to a return pad. It uses non-saline irrigation and carries a small risk of dilutional TUR syndrome if excessive fluid is absorbed.
Bipolar TURP
The electrical circuit is completed locally at the instrument and saline irrigation is used. It avoids classic TUR syndrome and generally has a more favourable perioperative bleeding and irrigation profile.
Technique choice also depends on available equipment, surgeon experience, prostate anatomy and individual risk. “Bipolar” does not eliminate every bleeding, fluid, urethral or anaesthetic complication.
Why Are a Catheter and Bladder Irrigation Used?
The catheter drains urine and supports the freshly resected prostate channel. Continuous bladder irrigation can run through one channel and return through another, preventing small clots from accumulating while early bleeding settles.
Irrigation is reduced or stopped when the returning fluid is sufficiently clear. Catheter removal depends on bleeding, urine drainage, operation size, bladder function and any additional procedure. Some men temporarily cannot urinate after removal and require another period of drainage.
Do not adjust a postoperative irrigation system yourself
If the catheter stops draining, the bladder becomes painful, fluid leaks heavily around the tube or large clots appear, contact the clinical team immediately. Clamping, flushing or reconnecting requires specific instruction.
What Happens to the Removed Tissue?
The prostate chips are sent to the pathology laboratory for microscopic examination. The report usually describes benign nodular enlargement, inflammation and whether cancer is seen in the sampled tissue.
An unexpected cancer finding does not by itself provide the complete grade, burden or stage. Further assessment may be needed. Conversely, a benign TURP specimen cannot exclude cancer in prostate areas that were not resected.
Urine Flow, Urgency and Bladder Recovery
Urine flow often improves quickly after the catheter is removed, but burning, frequency and urgency may initially be more noticeable. A bladder that has worked against obstruction for years can remain overactive or weak after the channel is opened.
TURP cannot guarantee that every urinary symptom will disappear. Persistent nocturia may reflect sleep, fluid balance or other medical conditions, while a poorly contracting bladder can leave residual urine despite technically adequate resection.
Ejaculation, Erections and Fertility
Retrograde ejaculation is common after TURP. Semen travels backward into the bladder rather than forward through the urethra, so orgasm may feel similar but little or no semen appears. The semen later leaves harmlessly with urine.
This can substantially reduce natural fertility and should be discussed before surgery if future biological children matter. TURP does not intentionally remove the structures responsible for erections, but erectile change is possible and pre-existing sexual health, vascular conditions and age also matter.
Retrograde ejaculation is not urinary incontinence. It also does not mean that the prostate has been completely removed.
What Should I Expect After TURP?
Early blood staining, burning, frequency, urgency, bladder spasms and temporary leakage can occur. Urine colour may vary as the internal prostate cavity heals, and delayed bleeding can occur when healing tissue separates.
Hospital stay and recovery depend on bleeding, catheter removal, ability to urinate, infection risk, bladder strength, medical conditions and any simultaneous stone procedure. Follow the individualized discharge plan rather than a fixed timetable.
After TURP
Contact the Hospital Urgently If
- You develop fever, chills, confusion or feel progressively unwell.
- Bleeding becomes heavy, increasingly red, contains large clots or is accompanied by faintness or weakness.
- You cannot pass urine after catheter removal or develop painful lower-abdominal fullness.
- A catheter stops draining, irrigation does not return or the bladder becomes painful despite the tube.
- You develop chest pain, breathlessness, one-sided leg swelling or another sudden serious symptom.
- Pain or vomiting is severe, persistent or worse rather than better.
Possible Risks and Limitations
Bleeding and clot retention
Bleeding may require prolonged irrigation, catheter traction, transfusion, endoscopic clot removal or repeat bleeding control.
Urinary infection or urosepsis
Bacteria can cause local or systemic infection despite appropriate assessment and perioperative precautions.
Temporary retention
Swelling, clots or a weak bladder can prevent urination after catheter removal and require renewed drainage.
Urethral stricture or bladder-neck contracture
Later scar narrowing can reduce flow and require another endoscopic procedure.
Urinary incontinence
Urgency leakage or temporary reduced control can occur; persistent stress incontinence is less common but important.
Incomplete relief or retreatment
Bladder dysfunction, residual obstruction, tissue regrowth or later scarring can cause persistent or recurrent symptoms.
Other risks include retrograde ejaculation, erectile change, fluid or electrolyte disturbance, bladder or ureteric-opening injury, and anaesthetic or cardiovascular complications. Individual risk depends on prostate size, operation time, medical history and technique.
What Is TUR Syndrome?
Classic TUR syndrome is a fluid and electrolyte disturbance caused by absorption of non-saline irrigation during monopolar resection. It can cause nausea, confusion, blood-pressure change, breathlessness, visual symptoms or heart and neurological complications.
Modern monitoring, shorter operating times and bipolar saline systems have greatly reduced this risk. Any sudden confusion, breathing difficulty or circulatory change during or soon after surgery requires immediate assessment.
What Does Successful TURP Mean?
Success means that the prostatic channel is adequately opened, urine flow and emptying improve, complications are controlled and the patient’s main treatment goals are met. It does not require removal of the entire gland.
The operation record should document the technique, prostate tissue resected, bleeding, bladder findings, ureteric openings, catheter and irrigation plan, any simultaneous procedure and whether tissue was sent for histopathology.
Recovery and Follow-Up
- Follow the individualized discharge plan for catheter care, fluid intake, activity, bathing, driving, work and sexual activity.
- Do not clamp, flush, pull or reconnect a catheter or irrigation system unless specifically instructed by the clinical team.
- Attend the planned catheter removal or trial without catheter and seek review sooner if drainage stops.
- Obtain and discuss the histopathology result from the removed tissue.
- Attend follow-up assessment of symptoms, urine flow and post-void residual when requested.
- Continue appropriate prostate and PSA follow-up because prostate tissue remains after TURP.

Common Myths
Frequently Asked Questions
What does TURP stand for?
TURP means transurethral resection of the prostate: endoscopic removal of obstructing central prostate tissue through the urethra.
Does TURP require an external incision?
No. The resectoscope passes through the natural urinary passage. TURP is still an operation requiring anaesthesia and postoperative monitoring.
Is the whole prostate removed?
No. TURP creates a channel by removing part of the transition-zone tissue. The outer prostate remains.
Which prostate sizes are commonly treated with TURP?
TURP is commonly used for glands around 30–80 mL, but anatomy, surgeon experience, operation time, bladder function and alternative techniques matter more than a rigid cutoff.
What is the difference between monopolar and bipolar TURP?
Both resect tissue with an electrical loop. Bipolar current is confined locally and uses saline irrigation, avoiding classic dilutional TUR syndrome while providing similar symptom improvement.
Will I definitely need a catheter?
A temporary bladder catheter is routinely used after most TURP procedures to maintain drainage and allow irrigation when needed.
Why might I be unable to urinate after catheter removal?
Swelling, clots, temporary bladder inhibition or longstanding weak bladder contraction can delay natural emptying. Another period of drainage may be needed.
Will TURP cure urgency and waking at night?
Not always. Outlet-related symptoms may improve, but bladder overactivity, weak contraction, sleep disturbance, fluid balance and other medical causes can persist.
What is retrograde ejaculation?
Semen travels into the bladder during orgasm rather than forward through the urethra. It is common after TURP and can reduce natural fertility.
Does TURP cause erectile dysfunction?
TURP does not intentionally remove the erection nerves, but erectile change is a recognized possibility. Pre-existing sexual function, age and vascular health also influence outcomes.
Can TURP cause urinary leakage?
Temporary urgency leakage or reduced control can occur. Persistent stress incontinence is less common but requires assessment and management.
Why is the removed tissue sent to pathology?
Microscopy confirms the nature of the tissue and can occasionally identify unsuspected cancer or another finding that changes follow-up.
Can the prostate grow back after TURP?
Prostate tissue remains and can enlarge over time. Some men later need treatment for regrowth, residual obstruction or scar narrowing.
How soon can I return to work or driving?
This depends on anaesthesia, bleeding, catheter status, urinary control and job demands. Follow the individualized discharge advice rather than a fixed online timetable.
When is higher-centre referral appropriate?
A very large prostate, complex urethral or bladder disease, major bleeding risk, previous failed surgery, suspected cancer or a need for advanced enucleation or reconstruction may require specialist care.
