In short

The diary reports successful medical removal, but Mr. Okada's explanation about doctors' skill remains his opinion.

Mr. Okada advises medical consultation and says he can sometimes share a doctor's details with permission.

The latest supplied entry discusses ceramic reinforcement; it does not establish current treatment options.

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: stuck chip removal

The OK Prostate Chip is a small device placed in the urethra (the urine passage) to act on the prostate. This topic concerns forceps (gripping instruments) used by doctors to remove a chip or broken piece retained inside the body. The accounts describe objects near the prostate or inside the bladder. Mr. Okada links removal outcomes to individual doctors' skill, but these are customer reports rather than a medical comparison.

A November 2020 stuck chip report prompted Mr. Okada's claim about doctors' skill

In an entry published in November 2020, a customer reported a chip that had not come out during urination. The customer later described getting it out without medical removal, after searching online for an approach. The customer also warned that the attempt involved risks, including risks they could not identify.

Mr. Okada welcomed the outcome but wrote that he had no personal experience with the gel involved. He believed successful forceps removal depended heavily on doctors' dexterity; this was his interpretation, not a finding from that customer's treatment. Mr. Okada's stated first recommendation for someone facing this problem was consultation with a doctor.

A broken ceramic chip was removed with forceps at the fifth hospital

An entry published in March 2024 reported successful forceps removal at the customer's 5th hospital. The chip had broken in half, leaving a ceramic piece about 25 mm long, 10 mm wide, and 5 mm thick. According to Mr. Okada, a well-known large hospital had said abdominal surgery was the only option.

A university hospital proposed general anesthesia (not explained in the diary) and an operation around the middle of the following month. Mr. Okada expressed relief at the eventual removal and said he was waiting for the customer's fuller report. He invited readers to send questions about the experience, including the customer's search for a hospital.

Successful stuck chip removal still involved hospitalization in the confirmed follow-up

In an entry published in May 2024, a customer sought help after another company's chip lost its retrieval thread (the attached removal thread). The stainless-steel chip measured 10 mm wide and 30 mm long; the customer reported that it had moved past the sphincter. Staff initially lacked details for a precise assessment; the customer later reported endoscopic removal (the diary does not explain this procedure).

The first doctor succeeded after warning that admission and an incision into the bladder might be necessary. A confirmed follow-up published in June 2024 recorded general anesthesia, 2 nights and 3 days in hospital, and ¥110,000 (about $704 at ¥156 = $1, rate as of 2026-09-04) with insurance applied. Mr. Okada called this his first reported endoscopic removal involving hospitalization and general anesthesia, and advised readers to consider their treatment preferences.

A June 2025 account recalled successful forceps removal of a complex ceramic tip

In an entry published in June 2025, Mr. Okada recalled an earlier accident involving a complex-tip ceramic chip (Umiushi 2). Its tip had broken off inside the body and remained in the bladder, where removal proved difficult. He reported that a doctor skilled at retrieval eventually removed the fragment with forceps.

Mr. Okada suspected an existing crack had gone unnoticed; he did not present that explanation as confirmed. No matching product can be confirmed on the current list. His proposed response was ceramic reinforcement intended to prevent broken pieces separating inside the body.

The maker's answer to stuck chip removal

Mr. Okada offers information about medical options while acknowledging that he cannot judge which hospital's treatment is correct.

Mr. Okada placed medical consultation first when discussing stuck chip removal

In the November 2020 entry, Mr. Okada discussed chips that had not passed for more than 1 week. He mentioned gel-assisted passage and medical removal with forceps as options to discuss with a doctor.

The account does not record a medical assessment of the customer's own attempt or establish a safe waiting period. Mr. Okada's first recommendation was consultation with a doctor before considering either option.

Mr. Okada's prototype tools had not achieved reliable stuck chip removal

By the March 2024 entry, Mr. Okada had made prototype tools intended for self-retrieval. He said they had not reached a state where reliable removal was possible. He also described their test footage as showing that safe removal was still beyond the prototypes.

Before receiving news of successful treatment, Mr. Okada had considered asking diary readers for information about a doctor likely to help. He speculated that large hospitals avoided techniques whose results depended on a particular doctor's skill, explicitly presenting this as his impression. His invitation to readers was to ask about the customer's experience finding medical help.

Staff described forceps removal as potentially straightforward before knowing the hospital outcome

In the May 2024 entry, staff answered before receiving the customer's hospital result. Their reply assumed a chip without a complicated shape and acknowledged uncertainty about its actual dimensions and design. They suggested that passage during urination might be possible, even if the chip had reached the bladder.

They thought forceps removal could be comparatively straightforward if a chip had not passed after about 1 week. Those were provisional staff opinions, not an examination or a promise about the customer's treatment. The reply's proposed medical route was consultation with a urologist.

Mr. Okada offered a possible referral for stuck chip removal with permission

In the June 2024 follow-up, Mr. Okada said earlier reports he had received usually described removal without admission. He said he could not determine why the treating doctor had chosen general anesthesia in this case. He advised people to consider their preferred treatment alongside the doctor's explanation.

If someone remained dissatisfied with a diagnosis, he said OK Lab might provide details of a doctor reported to be skilled at removal. That offer depended on permission from the person who shared those details, and he acknowledged surgery could still be necessary. Mr. Okada advised making a personal decision, emphasizing that OK Lab could provide information but could not judge competing treatments.

Ceramic reinforcement addressed a fracture concern behind difficult stuck chip removal

The June 2025 entry described ceramic reinforcement using shape-memory wire and epoxy (a resin used to cover the reinforcement). Mr. Okada believed this could prevent broken pieces separating and leaving a tip inside the body, although he acknowledged ceramic could still crack. The diary does not record an outcome inside the body demonstrating that claimed protection.

The published reinforcement surcharge was ¥2,000 (about $13 at ¥156 = $1, rate as of 2026-09-04) excluding tax, above the normal ceramic-chip price, regardless of the difficulty of the work. No matching product can be confirmed on the current list. Mr. Okada proposed this reinforcement as a response to the earlier accident involving a retained ceramic fragment.

Common worries about stuck chip removal

OK Lab answered the customer's request for help even though the trapped chip came from another seller.

"Can OK Lab help with another brand's stuck chip?"

That was part of the customer's request published in May 2024: the broken-thread accident involved a chip bought from another seller. The customer apologized for bringing that product's problem to OK Lab, but asked for help getting it out. Staff responded while saying the information provided was insufficient for a precise judgment.

Mr. Okada later explained that reports involving any retained chip worried him because he had promoted the underlying idea. He had considered sharing information about a doctor known for retrieval if the first doctor failed. Mr. Okada described medical referral as his possible fallback when an initial doctor could not remove a chip.
