Bipolar enucleation of prostate is an endoscopic technique in which the adenoma is separated from the surgical capsule using bipolar plasma energy through a resectoscope, then removed with a morcellator. It uses equipment that many urology departments already own, which makes it attractive as a laser-free alternative. This guide explains what the technique requires in terms of generator, resectoscope and morcellator, and what to ask suppliers.
What plasma enucleation of the prostate means
In plasma enucleation, a bipolar loop or button electrode is used in saline to dissect along the plane between the adenoma and the capsule. The surgeon peels the lobes off the capsule instead of resecting them in chips, then pushes them into the bladder for morcellation. The clinical choice of technique, patient selection and expected outcomes belong to the urologist.
From an equipment viewpoint, the technique is an extension of bipolar TURP: a generator with a bipolar enucleation mode, a continuous-flow resectoscope, a video system and a morcellator. For the TURP baseline see TURP equipment guide and bipolar resectoscope for TURP.
Bipolar enucleation vs HoLEP: equipment view
HoLEP uses a holmium laser, a laser fibre and a resectoscope-type sheath, and also ends with morcellation. Bipolar enucleation replaces the laser with an electrosurgical generator and a bipolar electrode. For a department, the difference shows in capital cost, in staff training, in laser safety measures and in consumables. The clinical comparison belongs to guidelines and the surgical team; see HoLEP vs TURP and HoLEP versus other BPH technologies for further context.
If the department already has bipolar TURP and a morcellator, adding enucleation may need only a suitable generator mode and training. If it plans lasers, the HoLEP route is covered in HoLEP equipment.
The electrosurgical generator for TURP and enucleation
The generator sets tissue effect, so choose one with presets for the instrument you plan to use. The Richard Wolf HF-GENERATOR 2260 provides presets for monopolar and bipolar TUR-P, TUR-B, bipolar enucleation, laparoscopy and hysteroscopic resection. Its cutting power is up to 400 W and coagulation power up to 350 W, and touch-display navigation keeps the voltage within the limit permitted for the connected instrument.
Further details that matter when you evaluate an electrosurgical generator for TURP: RFID detection for quick set-up, bipolar electrode ignition that allows cutting without tissue contact, a toggle footswitch combining two profiles, and a LAN connection to core nova. The unit measures 300 × 159 × 419 mm and weighs 10.2 kg, so it fits on a tower or trolley easily.
- Check that the generator has a validated bipolar enucleation preset
- Ask which saline irrigation fluids and electrodes are approved
- Confirm footswitch layout for two profiles
- Verify service and software update arrangements
Resectoscope and morcellator: SHARK and PIRANHA
The SHARK resectoscope uses continuous-irrigation double sheaths in 22/24 Fr and 24/26 Fr, an inner sheath that rotates 360 degrees, enlarged irrigation taps and snap-on couplings. Its working elements remain compatible with earlier Richard Wolf sheaths, and it works with the ENDOCAM Logic HD PENDUAL camera head.
PIRANHA is the morcellation line designed to work with SHARK. The morcescope has two irrigation channels and a 5 mm working channel, and the telescope fits 24 Fr and 26 Fr outer sheaths. The Vmax blade rotates at 1500 rpm and comes in disposable and reusable versions. A suction pump with a separate container keeps the tissue suitable for histology. More general background is in the prostate morcellator guide.
Planning the room and next steps
Plan fluid management, a video tower, a footswitch layout for generator and morcellator, and storage for sheaths and blades. Include operating table positioning and fluoroscopy access where relevant, as discussed in urology operating room setup. Confirm device registration and facility licensing requirements with the relevant UAE authorities.

Frequently asked questions
Is bipolar enucleation the same as HoLEP?
No. Both enucleate the adenoma, but bipolar enucleation uses electrosurgical plasma energy through a resectoscope instead of a holmium laser. Both usually need a morcellator.
What generator do I need?
One with a validated bipolar enucleation preset and saline-compatible bipolar instruments, such as the Richard Wolf HF-GENERATOR 2260.
Does the technique need a laser safety programme?
Not for the electrosurgical part, but standard electrosurgical safety and fluid management rules still apply.
Can existing TURP resectoscopes be reused?
Possibly, if the sheath and working element are compatible. Check with the manufacturer; SHARK working elements are compatible with earlier Richard Wolf sheaths.
