What happens: prostate chip removal

The OK Prostate Chip is a small urethral device intended by its maker to act on the prostate. Its retrieval thread (the line attached for removal) can become inaccessible when it moves inside the body. This topic concerns recovery when the thread disappears, parts overlap, or the device moves into the bladder. The diary discusses tweezers, fluids, and special tools in that setting, alongside accounts requiring hospital treatment.

Chip removal became difficult when rotation pulled the thread inward

In an entry published in May 2018, a customer described the single glass chip turning halfway around after 6–7 hours. The safety chip (a small part on the thread) had also moved inside, and urination did not free the device. The customer eventually reported removal with tweezers and requested a thread change from 20cm to 25cm.

Mr. Okada said this was his first reported case of rotation in that part of the urethra. He offered thread replacement for ¥1,080 (about $7 at ¥156 = $1, rate as of 2026-09-04), as published in May 2018, and asked the customer to return the product for that service. The diary does not record whether the thread replacement was completed.

An exposed thread did not prevent trouble with chip removal

In an entry published in September 2020, a customer sought help with a sea-slug-shaped chip (Sea Slug ver.4) stuck after ejaculation. The thread remained outside, but attempted removal caused some bleeding. Mr. Okada suggested that the thread's attachment near one end made the direction of force unhelpful.

He mentioned lubricant (liquid or gel intended to reduce friction), while acknowledging no experience with that proposal. The customer's confirmed follow-up reported removal the next day. Mr. Okada advised consulting a urologist if the device remained stuck.

A broken cable led to hospital care before chip removal

Entries published in November 2020 describe a custom wired chip whose exposed cable broke, leaving the device in the bladder. Hospital forceps (grasping instruments) could not grip it; a confirmed follow-up reported removal at home involving warmed drinking jelly. The customer described about 5 attempts and roughly 10 minutes for the final stage.

The customer warned against continuing through injury, pain, or other symptoms, and raised possible jelly entry into sperm-carrying ducts. Mr. Okada warned against cables with exposed metal, which he said would break through repeated stress or corrosion. In the follow-up, he put consultation with a doctor first.

Overlapping parts caused repeated trouble with prostate chip removal

In an entry published in August 2022, a customer reported a short M resin chip stuck against its companion chip. Around 10 syringe attempts involving water, lubricant, and air failed; hospital removal took place on the 5th day. Clinicians separated the parts, and the customer reported about ¥8,000 (about $51 at ¥156 = $1, rate as of 2026-09-04) under Japanese health insurance.

A confirmed September 2022 follow-up clarified that the parts appeared parallel, without rotation; Mr. Okada accepted that correction. The customer also reported a later episode involving extensive lubricant and massage, ending in removal after 3 hours. Mr. Okada emphasized moisture and warned against forceful pulling when the urethra was dry.

A dedicated wire addressed small loop fit during chip removal

In an entry published in April 2025, Mr. Okada introduced a dedicated wire because the multipurpose hook was too large for certain loops. The new tool used 0.7mm stainless steel, measured 20cm, and cost ¥500 (about $3 at ¥156 = $1, rate as of 2026-09-04) excluding tax, as published then. He offered it free to existing purchasers of the 0.2mm wire loop products.

The entry describes a tool for those loops. Mr. Okada recommended purchasing it with future orders of the relevant loop products.

Tweezers failed before hospital surgery for a stuck chip

In an entry published in June 2025, a customer outside Japan reported the sea-slug-shaped version 4 entering the bladder during sleep. The customer had previously shortened its cord; the diary does not establish why the whole cord later disappeared. Attempts involving forceful urination and tweezers failed.

The customer reported worsening difficulty urinating and frequent urination, followed by hospital surgery the next day. Mr. Okada speculated about how clinicians retrieved it, but the diary does not confirm the hospital's exact technique.

The maker's answer to prostate chip removal

Mr. Okada's proposals ranged from fluid-based ideas to special tools, with explicit warnings and gaps in testing.

A tangled cord complicated the maker's early thinking about chip removal

In an entry published in October 2017, Mr. Okada proposed that a bladder fuller with urine could let a tangled cord float more freely. He thought this might reduce friction between sections of cord and allow it to come free. He also warned that a knot inside the bladder could prevent removal.

An early chip removal proposal carried an explicit bladder warning

In an entry published in March 2018, Mr. Okada discussed air pressure and a 5mm straw as an approach to adhesion. His idea was that pressure might separate a stuck chip from the urethral wall. He also proposed water or non-sticky jelly for adhesion that air alone did not resolve.

These were Mr. Okada's proposed measures, and the entry did not present a confirmed customer outcome for them. He warned that excessive air could reach and expand the bladder, potentially causing rupture.

The retrieval basket for stuck chips had no bladder test

In an entry published in July 2021, Mr. Okada described a retrieval basket (an experimental cage of threads for capturing a chip). Its 6 threads were intended to improve the chance of capturing a slippery device. He explicitly said that bladder insertion testing had not happened.

He planned custom manufacture on request, with no regular commercial release planned. Mr. Okada proposed hospital use with an endoscope (an internal viewing instrument), warning that retrieval without seeing the chip would be difficult.

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.

Common worries about prostate chip removal

Readers asked about missing threads, overlapping parts, cutting cables, and whether other tools could help.

"Can tweezers help with chip removal after the thread disappears?"

In an entry published in March 2019, a customer with a cross-jointed resin chip asked whether hospital care was necessary. Mr. Okada discussed tweezers conditionally, depending on the location of the safety chip; he also raised possible hospital retrieval. A confirmed follow-up reported that the chip came out during urination.

The customer then asked about preventing a repeat. OK Lab's sales reply recommended an external stopper to keep the thread accessible, or an internal stopper to limit inward movement.

"Would cutting the cable solve a stuck chip?"

In an entry published in December 2022, a customer with a custom linked chip asked about cable cutting after the parts became trapped. Mr. Okada accepted the idea in theory but warned that exposed cut wires could injure the urethra.

The customer's follow-up said a urologist rejected cutting because a broken thread could complicate retrieval, and removed the device without cutting. The customer reported a small injury and ¥1,760 (about $11 at ¥156 = $1, rate as of 2026-09-04) in treatment costs under Japanese national health insurance. Mr. Okada's advice had been that medical assessment was safer.

"Can a screw-shaped add-on make chip removal harder?"

In an entry published in January 2023, a customer asked about rotation after a custom chip with a screw-shaped companion became stuck. Home attempts initially failed; eventual removal was followed by about 2 days of high fever. The customer later reported recovery.

Mr. Okada thought the companion might have tilted and the thread become trapped between the parts. He advised against rushing removal, but the diary does not establish the internal position or the fever's cause.

https://ok-lab.hatenablog.com/entry/2023/01/07/123115

"Could a multipurpose wire solve a stuck chip?"

In an entry published in April 2026, a customer reported a broken thread, about a week without passage, and pain during urination. The customer asked about a multipurpose wire; staff warned that its hook could slip and movement could send the chip into the bladder. Staff suggested a lubricant-based approach might carry less risk, but the exchange records no successful result.

Mr. Okada also discussed a different, untested tool concept and explicitly said it would not ensure removal. The diary does not record whether this customer's device was subsequently removed.
