Bipolar TURP surgery is an endoscopic operation for urinary blockage caused by an enlarged prostate. A urologist passes a telescope through the urine pipe and removes the inner obstructing part of the prostate using bipolar electric energy. There is no external cut. It is commonly advised when prostate medicines do not help enough, urine flow is very weak, a catheter is needed, or the enlarged prostate is affecting the bladder or kidneys. Bipolar TURP gives symptom relief similar to traditional TURP, but uses saline irrigation and has a better safety profile for certain operation-related risks.

What is bipolar TURP surgery?

Bipolar TURP means bipolar transurethral resection of the prostate.

“Transurethral” means the surgery is done through the urethra, which is the urine passage. “Resection” means removing tissue. In TURP, the surgeon removes the inner enlarged part of the prostate that is blocking urine flow.

The whole prostate is not removed. This is different from radical prostatectomy, which is a cancer surgery where the full prostate gland is removed.

In bipolar TURP, a telescope-like instrument called a resectoscope is inserted through the urine passage. A small electric loop shaves the prostate tissue from inside and opens the blocked channel. The removed pieces of prostate tissue are washed into the bladder and removed at the end of surgery. These tissue chips are usually sent for histopathology testing.

Why does an enlarged prostate need surgery?

An enlarged prostate, also called BPH (benign prostatic hyperplasia), can press on the urine channel. This may make the bladder work harder to push urine out.

At first, many men are treated with medicines. Surgery is considered when symptoms are severe, medicines are not working, or complications are developing.

Bipolar TURP surgery may be advised if you have:

• Very weak urine stream.
• Straining to pass urine.
• Frequent urination at night.
• Feeling of incomplete emptying.
• Repeated sudden inability to pass urine.
• Dependence on a urinary catheter.
• Recurrent urine infections due to poor emptying.
• Bladder stones caused by obstruction.
• Blood in urine after proper evaluation.
• High post-void residual urine.
• Kidney swelling or kidney function changes due to blockage.
• Side effects from prostate medicines.
• Symptoms affecting sleep, travel, work or daily comfort.

The decision is not based only on prostate size. A small prostate can cause severe blockage, and a large prostate may not always need surgery. The urologist looks at symptoms, urine flow, residual urine, prostate shape, kidney function, PSA and overall fitness.

When is bipolar TURP better than continuing medicines?

Medicines can relax the prostate channel or slowly reduce prostate size. They are useful for many men. But medicines may not be enough when the blockage is advanced.

Surgery may be a better option when:

• You have had urinary retention.
• You need repeated catheterisation.
• The bladder is not emptying well.
• Medicines give poor relief even after adequate trial.
• You cannot tolerate dizziness, weakness, low BP or sexual side effects from medicines.
• There is repeated infection, bleeding, bladder stone or kidney back-pressure.
• You want a more definitive solution after understanding benefits and risks.

TURP does not treat every urinary symptom. If frequent urination is mainly due to diabetes, excess evening fluids, sleep disturbance, overactive bladder or urine infection, those issues may need separate treatment.

Who may not be ideal for bipolar TURP?

Bipolar TURP is useful for many men, but it is not the best operation for everyone.

It may not be ideal if:

• The prostate is very large and needs enucleation-type surgery such as HoLEP or bipolar enucleation.
• The main problem is a weak bladder muscle rather than prostate blockage.
• Urinary frequency is mainly due to overactive bladder, diabetes, sleep problems or high fluid intake.
• There is active urine infection that needs treatment before surgery.
• The patient is medically unfit for anaesthesia at that time.
• Blood thinners cannot be safely managed and another technique is more suitable.
• The patient strongly wants to preserve ejaculation, because TURP commonly causes dry orgasm.

This is why a preoperative evaluation matters. Surgery should match the patient, not just the prostate size.

Bipolar TURP vs traditional monopolar TURP

Both monopolar and bipolar TURP aim to remove the obstructing prostate tissue. The main difference is the energy system and irrigation fluid.

NICE notes that bipolar systems such as PLASMA have comparable clinical outcomes to monopolar TURP, while reducing TUR syndrome risk, blood transfusion need and hospital stay in their reviewed evidence.

What is TUR syndrome?

TUR syndrome is a rare but serious fluid absorption problem that was mainly associated with older monopolar TURP systems using non-saline irrigation fluid. It can cause low sodium, confusion, nausea, blood pressure changes and serious complications.

Bipolar TURP uses saline irrigation, which greatly reduces this risk. This is one of the important advantages of bipolar TURP.

Bipolar TURP vs HoLEP and laser surgery

Patients often ask: “Should I do TURP or laser?”

The honest answer is: it depends.

EAU guidelines list bipolar or monopolar TURP as standard surgical options for men with moderate-to-severe symptoms and prostate size around 30-80 mL. HoLEP is also an excellent option, especially for larger glands, but availability, cost, anatomy and surgeon experience matter.

For many men, bipolar TURP remains a practical, proven and effective operation.

How is bipolar TURP surgery done?

Bipolar TURP is usually done under spinal anaesthesia or general anaesthesia.

The usual steps are:

1. You are given anaesthesia.
2. A telescope is passed through the urine passage.
3. The bladder and prostate channel are inspected.
4. The inner obstructing prostate tissue is shaved using a bipolar loop.
5. Bleeding points are sealed.
6. Prostate chips are washed out.
7. A urinary catheter is placed.
8. Bladder irrigation may be started if urine is bloody.

No external incision is made. There are no stitches on the skin.

The catheter is important because the inside of the prostate has a fresh raw surface after surgery. The catheter keeps urine draining and allows clots or blood-tinged urine to clear.

For catheter-dependent patients and families

Many elderly men come for surgery after repeated urinary retention or after living with a catheter for days or weeks. Families often worry: “Will he pass urine normally after surgery?”

In many patients, bipolar TURP can remove the blockage and help them become catheter-free. But the result also depends on bladder strength. If the bladder has been overstretched for a long time, it may take longer to recover. Some patients may need a temporary repeat catheter after the first removal attempt.

This does not always mean failure. It often means the bladder needs time, infection control, follow-up and sometimes bladder-supportive treatment.

How long does the surgery take?

The actual operation time depends on prostate size, bleeding, anatomy, surgeon experience and whether the patient has a catheter or infection history.

Many TURP surgeries take around 45-90 minutes. Larger prostates may take longer. If the gland is very large, your urologist may advise HoLEP, bipolar enucleation or another procedure instead of standard TURP.

Hospital stay and catheter after bipolar TURP

Hospital stay is commonly around 1-3 days, but this varies.

The catheter is usually removed once urine is clear enough and the urologist feels it is safe. Some patients pass urine well immediately after catheter removal. Some may have burning, urgency or temporary leakage.

If the bladder has been overstretched for weeks or months due to retention, it may be weak. In such patients, catheter removal may take longer, or a repeat catheter may be needed temporarily.

Benefits of bipolar TURP surgery

Expected benefits include:

• Stronger urine flow.
• Less straining.
• Better bladder emptying.
• Reduced catheter dependence in many men.
• Fewer night-time toilet visits in many patients.
• Lower risk of repeated urinary retention.
• Reduced obstruction-related bladder pressure.
• Protection of kidneys when obstruction is affecting them.
• Tissue available for histopathology testing.

Most men notice improvement in flow early. Frequency and urgency can take longer because the bladder may remain irritable for a few weeks.

Risks and side effects of bipolar TURP

Bipolar TURP is commonly performed and effective, but it is still surgery. Possible risks include:

• Blood in urine.
• Burning while passing urine.
• Temporary urgency and frequency.
• Urine infection.
• Clot retention needing bladder wash.
• Bleeding needing transfusion, uncommon but possible.
• Temporary leakage of urine.
• Failure to pass urine after catheter removal.
• Urethral stricture, meaning narrowing of the urine pipe.
• Bladder neck narrowing.
• Need for repeat surgery in future.
• Anaesthesia-related risks.

A very common long-term effect is retrograde ejaculation, also called dry orgasm. Semen goes backward into the bladder instead of coming out through the penis. It is usually not harmful, but it can affect fertility. MedlinePlus notes that reduced or absent semen after TURP may be permanent and can interfere with fathering a child naturally.

Erection problems are possible, but TURP is not mainly a surgery on erection nerves. Risk depends on age, diabetes, vascular health, smoking, testosterone status, medicines and pre-existing erectile function.

Myths and facts about bipolar TURP surgery

Recovery after bipolar TURP surgery

Recovery happens in stages.

MedlinePlus notes that many patients return to most normal activities within about 3-6 weeks after TURP.

What is normal after TURP?

These can be normal during healing:

• Mild blood in urine.
• Burning while passing urine.
• Sudden urge to pass urine.
• Passing urine frequently.
• Small clots occasionally.
• Temporary leakage before reaching the toilet.
• Blood appearing again after increased activity.

Symptoms should gradually improve. If they worsen instead of improving, contact your urologist.

Follow-up after bipolar TURP

Follow-up usually checks:

• Urine flow.
• Burning or infection symptoms.
• Bleeding.
• Post-void residual urine.
• Histopathology report of prostate chips.
• Whether medicines can be stopped.
• Any persistent urgency, leakage or sexual concerns.

Many men can stop prostate relaxant medicines after successful TURP, but this should be decided by the urologist. Some patients may temporarily need bladder-calming medicines if urgency persists.

If you have poor urine flow, repeated night urination, urinary retention, catheter dependence or medicines are no longer helping, a urology evaluation can help decide whether bipolar TURP surgery is suitable.
