In short

Some clinics referred chip-removal cases elsewhere, while others treated them locally.

Mr. Okada advised seeking a hospital with urology services and emergency facilities.

The February 2025 report records successful removal and a warning that the hospital would refuse a repeat visit.

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: urologist visits and chip removal costs

The OK Prostate Chip is a small device placed in the urethra near the prostate, according to the maker's description. This topic concerns medical visits after discomfort, injury, or a chip becoming trapped in the urine passage or bladder. Customers sought examination or removal, sometimes after a retrieval thread (the thread attached for removal) broke or disappeared inside. Their reports describe different clinic capabilities, referrals to other facilities, and separate charges for the care received.

A urologist visit required different equipment after a glass chip broke

In an entry published in February 2019, a customer sought examination after a glass chip emerged with its tip missing. The first clinic lacked a rigid cystoscope (a metal bladder-viewing instrument) and directed the customer to a larger hospital.

Another clinic had that equipment, but its preliminary scan found no foreign object. Later examination found no fragment, yet showed extensive damage to the bladder lining. The fragment's eventual passage was the customer's interpretation; it was never recovered. Mr. Okada shared the account as a caution for other users.

Calls about a stuck chip ended without either clinic appointment

In an entry published in April 2019, a customer reported a broken thread that left the leading resin chip inside. After urinary difficulty and bleeding, the customer called 2 clinics, felt treated with suspicion, and abandoned attempts to arrange a visit.

The chip was recovered outside medical care five and a half days after the thread broke. The customer requested an additional thread, and Mr. Okada supplied a separate replacement with two threads instead of repairing the returned chip. No matching product can be confirmed on the current list.

A stuck chip required hospital treatment when local clinics lacked tools

In an entry published in August 2022, a customer sought treatment for overlapping chips that could not be removed. 2 local urology clinics had viewing equipment but lacked forceps (grasping instruments), so they recommended a larger facility.

A large urology hospital removed the chips; the customer said the doctor did not scold them. The treatment was classified as surgery and cost about ¥8,000 (about $51 at ¥156 = $1, rate as of 2026-09-04) with insurance, with infection medicine and pain relief prescribed. The customer reported damaged urethral lining and a warning about possible changes in urination after healing. Mr. Okada cautions users about the risks of connected chips.

A clinic referral led to ceramic fragmentation and several treatment charges

In an entry published in August 2023, a clinic said it could not remove a trapped ceramic chip and referred the customer elsewhere. The report describes fragmentation and removal, followed by five bladder washouts (flushing to clear remaining fragments).

Reported charges were ¥48,000 (about $307 at ¥156 = $1, rate as of 2026-09-04) for fragmentation and removal, plus ¥2,200 (about $14 at ¥156 = $1, rate as of 2026-09-04) × 5 for washouts. The customer stated a total of ¥59,000 (about $378 at ¥156 = $1, rate as of 2026-09-04) plus consultation fees, and reported bleeding during the washouts. The diary does not record the result of the planned follow-up examination. Mr. Okada suggests asking another doctor about fragmentation if an incision into the bladder is proposed.

A clinic refusal preceded successful treatment at a university hospital

In an entry published in October 2023, a customer reported that a chip had entered the bladder and would not come out. A private clinic did not provide treatment and referred the customer to a university hospital. Treatment there succeeded, but the diary does not identify the method used. Mr. Okada urges caution when sharing this report.

A small clinic completed chip removal despite initially discussing hospital referral

In an entry published in March 2024, a customer described seeking removal at a small local urology clinic. The doctor initially discussed referral to a general hospital because the device was unfamiliar.

The clinic nevertheless completed thread retrieval and chip removal in under 30 minutes, costing ¥27,000 (about $173 at ¥156 = $1, rate as of 2026-09-04). According to the customer, removal caused neither injury nor snagging, and the doctor praised the device on that basis. Mr. Okada writes that he would discuss treatment directly with a local doctor if he faced a similar problem.

Chip removal costs included hospital admission in the confirmed follow-up

An entry published in May 2024 described a retained stainless-steel chip made by another company. OK Lab staff expected medical removal might be straightforward, but the follow-up published in June 2024 documented hospital admission.

The customer reported admission on the consultation day, general anesthesia (the diary does not explain this), and a stay of two nights and three days. The reported cost was ¥110,000 (about $704 at ¥156 = $1, rate as of 2026-09-04) with insurance, and the customer said the recorded diagnosis was narrowing of the urethra. Mr. Okada acknowledged that he could not judge why this treatment was chosen. He advises discussing treatment preferences with the doctor.

Successful chip removal came with a warning against returning for treatment

In an entry published in February 2025, a customer sought help after a chip and its 35cm retrieval thread disappeared inside. OK Lab staff advised following the doctor's treatment plan and providing a photograph showing the device's structure.

Removal succeeded, costing ¥25,000 (about $160 at ¥156 = $1, rate as of 2026-09-04) for surgery and about ¥35,000 (about $224 at ¥156 = $1, rate as of 2026-09-04) including scans, the initial consultation, and medicines. However, the hospital said it did not normally remove foreign objects and would refuse a repeat visit. The customer reported infection after injuries and bleeding during removal, followed by mild fever and exhaustion. Mr. Okada cautions that a stopper (a movement-limiting part) cannot guarantee protection against a chip entering the bladder.

The maker's answer to urologist visits and chip removal costs

Mr. Okada's advice includes accepting medical care and recognizing that a clinic may lack the equipment needed for removal.

A urologist visit brought a warning against rough ceramic chips

In an entry published in June 2019, Mr. Okada described seeking care after testing a rough ceramic chip. He reported a diagnosis of urethral injury after developing a fever of 37.5°C. According to his account, the doctor examined the chip and repeatedly said it was dangerous and should be abandoned.

Mr. Okada continued describing its appeal but also acknowledged the injury risk. No matching product can be confirmed on the current list. His closing warning asks others not to imitate that experiment.

The maker's urologist guidance excluded people unable to seek care

In an entry published in July 2021, Mr. Okada published draft instructions containing warnings about who should avoid the product. One warning concerned people unable to visit a urologist when they noticed urinary abnormalities. A separate warning addressed people already receiving medical treatment or experiencing physical problems. For those situations, the draft advises consultation with a doctor.

The maker's stuck chip guidance pointed toward hospitals accepting emergencies

A separate part of the instructions published in July 2021 discussed obtaining hospital help for a retained chip. Mr. Okada wrote that private practitioners generally would not agree to removal. He described hospitals with bladder-viewing equipment as places where a retained object could be located during treatment. His advice was to seek a hospital with urology services large enough to accept emergency patients.

Common worries about urologist visits and chip removal costs

The reader questions concern embarrassment, treatment expense, urinary problems, and whether the maker can help with a retained device.

"Will a urologist visit be embarrassing or expensive?"

In an entry published in August 2020, a customer wanted advice about urinary discomfort while avoiding an embarrassing or inconvenient visit. Mr. Okada compared a urology visit to an ordinary medical consultation.

He estimated that a first visit, including medicine, would cost within ¥3,000 (about $19 at ¥156 = $1, rate as of 2026-09-04). That was his estimate for the symptoms being discussed, rather than a recorded bill for removing a chip. The diary does not record whether this customer subsequently received a diagnosis. Mr. Okada encourages a urologist visit instead of continued worry.

"Has anyone reported being unable to urinate after chip use?"

In an entry published in May 2022, a customer living in the United States asked whether similar urinary problems had been reported. The customer described being unable to urinate for 3–4 hours, sometimes about 10 hours, after use.

Medical expense and difficulty explaining the situation had discouraged a visit. Mr. Okada said he had not experienced this problem himself; the diary records no medical diagnosis or later clinical outcome. His reply invited other users to share similar experiences.

"Can OK Lab help when a chip cannot be removed?"

In an entry published in December 2022, a customer asked about altering a connection because a custom chip could not be removed. Staff expressed concern about injury from that idea; a clinic subsequently removed the device without the proposed alteration. The customer reported minor injury, a week of medicine for infection, recovery, and ¥1,760 (about $11 at ¥156 = $1, rate as of 2026-09-04) in treatment costs under Japan's public National Health Insurance.

The customer had researched clinics offering surgery and brought photographs and a similar device to explain the problem. No matching product can be confirmed on the current list. OK Lab staff advised medical assessment as the safer option.
