In short

• Repair possibilities depend on the damaged part, its material, and how it was attached.
• The maker has offered repairs, replacement parts, or refunds when rebuilding would not resolve the problem.
• A ceramic model discussed below remains listed; the latest repair reply still requires assessment of the damage.

If you see blood in your urine, even a small amount or for the first time, do not wait and see. See a urologist right away.

If you suddenly cannot urinate, or the device cannot be removed, do not try to fix it yourself. Go to a medical facility, including emergency care, immediately.

What happens: prostate chip repair

The OK Prostate Chip is a device placed in the urethra (the urine passage) to press on the prostate. Repairs concern its retrieval thread (the line intended for withdrawal), its body, and electrical parts on vibrating models. The diary describes damaged connections, broken surfaces, and failed cables, with different repair limits for each material. When a repair could not address the problem, some replies offered a replacement, refund, or changed connection.

Glass chip repair began with a paid thread replacement service

In an entry published in April 2018, a customer asked about repair after the thread attachment began separating. Mr. Okada introduced a glass-chip thread replacement service at ¥1,000 (about $6 at ¥156 = $1, rate as of 2026-09-04) excluding tax per chip. He explained that handmade replacements could not reproduce a favorite chip exactly, and suggested this service when the glass remained intact.

Resin chip repair required a different kind of thread attachment

In another entry published in April 2018, a customer returned a resin chip after its thread detached. Mr. Okada said the original connection embedded in resin (the material securing the thread) could not be recreated. His available repair was a surface attachment like the connection used for glass chips, which he reports completing.

Rough resin repair could leave the same snag behind

In an entry published in June 2018, a customer reported pain and occasional bleeding from a raised resin edge. Mr. Okada suspected thicker coatings, introduced against thread detachment and peeling, might contribute. He said a local repair was unavailable: the entire thread assembly would need replacement. Even then, he could not promise that the replacement would be free of another snag.

Chip resizing was refused, but a replacement motor was offered

In an entry published in March 2019, a customer asked whether an oversized vibrating chip could be reshaped. Mr. Okada refused reshaping after the chip had been used. He quoted glass-chip thread replacement at ¥1,000 (about $6 at ¥156 = $1, rate as of 2026-09-04) excluding tax, and motor replacement at ¥3,000 (about $19 at ¥156 = $1, rate as of 2026-09-04) excluding tax.

The diary does not record whether this customer accepted the proposed replacement. Mr. Okada offered an 8 mm motor (the vibration-producing unit) as the only change he could provide for that request.

Motor thinning reduced thickness while leaving long-term durability uncertain

In an entry published in August 2019, a customer found an 8 mm motor assembly too thick. Its resin-covered thickness was approximately 6 mm, a different measurement from the motor's stated size. Mr. Okada accepted the returned unit and reported a finished thickness of 5 mm.

The diary does not record how the altered unit felt afterward. Mr. Okada warned that the thinner covering reduced strength and that long-term durability was not guaranteed.

An unrepaired broken cable left a chip trapped in the bladder

In an entry published in November 2020, a customer continued using a chip after repeated repairs failed to keep its cable covering attached. The cable broke, leaving the chip trapped. Mr. Okada initially expected it to pass naturally, but medical assessment found it in the bladder.

An initial hospital removal attempt failed. The next-day update reports that the customer subsequently removed it without medical assistance. Mr. Okada regretted not giving a clearer warning and advised against using cables with exposed wires.

An overheated chip became unsuitable for replacement thread after glass cracked

In an entry published in September 2021, a customer reported at least 10 minutes of accidental heating after the water boiled away. The thread deteriorated and the resin changed color. Staff initially offered thread replacement, but a follow-up reporting cracked glass ruled that out.

The initial quotation was ¥1,100 (about $7 at ¥156 = $1, rate as of 2026-09-04), plus a ¥400 (about $3 at ¥156 = $1, rate as of 2026-09-04) handling fee, with possible differences for attached options. OK Lab's staff advised against using the heat-damaged thread; replacing it could not resolve the cracked glass.

Broken wire repair could also require replacing the motor

In an entry published in July 2022, a customer reported protruding wire from a 4-wire attachment (a wire-and-cable support). The customer asked about changing to an enhanced 6-wire version. Mr. Okada said neither attachment's wires could themselves be repaired; replacement on a vibrating model also required a new motor.

The diary does not record a completed replacement for this customer. Mr. Okada cautioned that the stronger versions could still develop protruding wire.

Broken wire reports ended orders for one stainless-steel configuration

In an entry published in September 2022, a customer reported connection failure after 3 uses of a stainless-steel chip. Its wire-in-tube connection used wire inside silicone tubing to support the chip. Staff treated the early breakage as an initial defect.

Mr. Okada then stopped accepting orders for this stainless-steel configuration. He offered different connections for affected orders and previously supplied products, including used ones.

Chip refund replaced repair when early wire failures remained unexplained

In an entry published in February 2025, a customer requested support after a loop-only device's wire broke. Staff said the cause remained unknown, so repair or remaking would not resolve it. They offered a refund because the product had been shipped recently.

The customer confirmed receiving the refund. Staff directed the customer to future diary announcements for any revised design.

The maker's answer to prostate chip repair

The diary distinguishes repairable damage from failures that require replacement, a changed design, or a refund.

Cracked glass repair depended on whether damage was local

In an entry published in October 2019, a customer asked about a glass chip whose surface had partly flaked away. Mr. Okada considered a small, isolated defect potentially repairable with resin filling. The filling itself was free, but the associated thread replacement carried a charge. He advised stopping use if the glass showed signs of cracking more widely.

Wire replacement restrictions narrowed the standard service to nylon thread

In an entry published in August 2022, Mr. Okada said wire-in-tube, 4-wire, and 6-wire replacements would generally no longer be accepted. He explained that separating their bonded connections could break the chip itself. The standard replacement service was therefore limited to ordinary nylon thread. He invited individual inquiries about specially valued or modified chips, without promising acceptance.

Chip refund became the response as early failures suspended sales

In an entry published in October 2022, a customer rejected a free wire-in-tube repair and requested a different stainless-steel chip. OK Lab declined that product change and offered a refund instead. Following further early failures, Mr. Okada temporarily suspended both the historical 6-wire and wire-in-tube ranges. He offered refunds to owners who objected to the risks of those products.

Integrated stopper repair concerns led to a changed attachment design

In an entry published in November 2025, a customer found protruding wire after experiencing bleeding with an integrated stopper. Mr. Okada initially offered a refund because remaking it could reproduce the same failure. Later in the entry, he reported changing the design so its thread was bonded to the ceramic body. He asked customers to report further detachment.

Common worries about prostate chip repair

"How much did broken cable repair cost?"

In an entry published in May 2019, a vibrating-chip owner asked about a fault near the motor. Mr. Okada offered free initial-defect repair if the failure was within the resin-covered part. Cable reconnection cost ¥1,080 (about $7 at ¥156 = $1, rate as of 2026-09-04); damage within 3 cm of the chip required motor-and-cable replacement at ¥3,240 (about $21 at ¥156 = $1, rate as of 2026-09-04).

An electronic controller (the vibration control unit) cost ¥2,160 (about $14 at ¥156 = $1, rate as of 2026-09-04) to replace; a basic battery box cost ¥1,080 (about $7 at ¥156 = $1, rate as of 2026-09-04). The diary does not record this customer's eventual repair. Mr. Okada's response made the available service depend on where the fault occurred.

"Can cracked ceramic be repaired without changing its size?"

In an entry published in July 2024, a customer asked about a twisted ceramic chip broken in an earthquake. Staff said repair might be possible, depending on the break, but reinforcement would increase thickness and alter its appearance. Mr. Okada reports attempting the repair.

Staff offered this repair free as an earthquake-related exception, provided the damage was repairable. They cautioned that strength after repair could not be guaranteed.

"Does peeling coating qualify for chip repair or replacement?"

In an entry published in June 2026, a customer reported peeling reinforcement on a twisted ceramic chip after 2 uses. The customer asked whether it remained usable or qualified for replacement. Staff could not judge its condition from the message alone.

They explained that the reinforcement now combined resin and rubber. The diary does not record an inspection result. OK Lab offered assessment and repair if the condition interfered with use.
