What happens: peeing with a chip in

The OK Prostate Chip is a small device placed in the urethra (urine passage) to act on the prostate. These entries concern external support intended to keep the device from moving outward while urine passes through or around its parts. They describe pressure through the skin over the urethra, with the supporting part differing between designs. Mr. Okada's reports include successful support, unexpected expulsion, and difficulty removing a hollow prototype.

Early advice about peeing with a chip in depended on accessory shape

In an entry published in October 2017, Mr. Okada described a flattened accessory near the penis head. He said its shape left room for urine on either side during external support.

The main chip could still move into the bulbar urethra (the wider part of the urine passage). Mr. Okada proposed the accessory as a barrier against complete expulsion.

Advice about linked support helped one customer keep a chip in while peeing

In an entry published in January 2018, a customer asked about preventing expulsion of a linked pair without an accessory. Mr. Okada proposed active support, and the customer subsequently reported urinating without expulsion.

He explained that a chip reaching the narrower passage could be expelled abruptly. His advice emphasized supporting the pair rather than expecting it to hold itself in place.

Peeing with a chip in preceded difficult removal during prototype testing

In an entry published in February 2018, Mr. Okada reported urine passing through a hollow linked prototype despite external pressure. Later, it resisted removal so strongly that he feared its retrieval thread (the connection intended for removal) would detach.

He suspected that drying outside the chip had made it adhere to the urethral wall. He also reported that a urologist's normal examination did not establish the chip's safety. Mr. Okada withheld sale until the suspected drying problem could be resolved.

A short ceramic chip coming out when peeing broke against the toilet

In an entry published in October 2019, a customer reported easier supported urination with a resin spiral chip. Their short ceramic chip shot out during urination, struck the toilet, and broke in half.

Mr. Okada said ceramic strength had improved that week, but acknowledged limited impact testing. He cautioned that resistance depended on where the ceramic was struck.

Peeing with a chip in improved after one customer changed external support

In an entry published in October 2019, a customer credited changed support direction with easier urination without expulsion. Their earlier support had also restricted urine flow. The same customer requested a resized ceramic design with a small spiral accessory.

OK Lab required a drawing for the changed design and agreed only to attempt the accessory. The diary does not record how the proposed combination worked in use. Mr. Okada welcomed the urination report as a suggestion for other users.

A blue starter chip could come out when peeing without external support

In an entry published in September 2021, Mr. Okada described a blue starter chip measuring 15mm long. He reported that ordinary urination could send it straight into the toilet.

He also softened an easy-placement claim after the accompanying wire sometimes brought the chip out. Mr. Okada advised external support, while acknowledging that it could fail.

Hollow accessories offered another urine passage for peeing with a chip in

In an entry published in December 2023, Mr. Okada proposed a hollow accessory with a rigid 4mm urine passage. He said that passage stayed open under external pressure near the penis head. A separate 2mm hole accommodated the tube tail (a tube-covered section of thread).

The proposed length was about 15mm, priced at ¥3,000 (about $19 at ¥156 = $1, rate as of 2026-09-04) excluding tax, with M and L versions planned. He noted that its smooth exterior could slide when unsupported. Mr. Okada cautioned that the new part had received little testing.

Later experiments still recorded a chip slipping out despite support

In an entry published in November 2025, Mr. Okada described a loop-linked prototype with spiral accessories. He reported sudden expulsion despite support when the urethra was especially slippery. A revised arrangement stayed inside during repeated urination in his tests.

He also found a version with four wire strands harder to remove. Mr. Okada suggested an external retrieval thread for anyone uneasy about a fully internal arrangement.

The maker's answer to peeing with a chip in

Mr. Okada's proposals depended on the support part's shape, location, and connection to the main chip.

Ring support for peeing with a chip in carried warnings about prolonged constriction

In an entry published in June 2019, Mr. Okada discussed ring support for curved-tail ceramic chips. His proposal relied on mild pressure around the penis base to limit movement.

He named a cushion for the penis head as an alternative to a ring. Mr. Okada cautioned against prolonged tight constriction, warning that it could damage tissue.

Spiral support aimed to preserve urine flow when peeing with a chip in

In an entry published in November 2019, Mr. Okada launched a spiral auxiliary chip (a twisted secondary support piece). He said it left urine passages open during external support in the penile urethra (the narrower passage within the penis). Standard dimensions were 15-18mm long and 8-9mm wide, with a published price of ¥3,000 (about $19 at ¥156 = $1, rate as of 2026-09-04) excluding tax.

The accessory had fixed spacing and could not be added after manufacture. Mr. Okada cautioned that this design could slip at the penis head.

A tube tail provided adjustable support for peeing with the chip inside

In an entry published in November 2023, Mr. Okada described a movable stopper on a 2.5mm tube tail. He intended the tube to reduce thread contact near the prostate. He reported that external support of the stopper in the bulbar passage limited movement while urine passed around it.

The stopper's hole was about 1.6mm, providing friction against the tube. Mr. Okada stressed that testing remained brief. He cautioned that the same stopper could obstruct urine in the narrower penile passage.

Common worries about peeing with a chip in

The diary distinguishes preventing complete expulsion from keeping a chip motionless.

"Can my semi-long chip slip out when peeing?"

In an entry published in September 2019, a semi-long vibrating-chip customer asked about urination and longer wear. Mr. Okada expected some outward movement despite support and discussed later repositioning.

The diary does not record whether this customer's problem was resolved. Mr. Okada's reply favored a reachable supporting part, with reservations about longer curved models fitting narrower urethras.

(Source: ok-lab's diary, published September 2019)
https://ok-lab.hatenablog.com/entry/2019/09/21/131939

"Why does my chip slip out after careful placement?"

In an entry published in November 2019, a glass-chip customer wanted longer wear after urination expelled their device. Mr. Okada attributed movement to the sphincters (muscles controlling the urine passage) opening during urination. He discussed support within the wider passage and acknowledged that repositioning might still be needed.

The diary does not record which replacement the customer ultimately chose. Mr. Okada cautioned against forcing movement when resistance remained.

https://ok-lab.hatenablog.com/entry/2019/11/09/132111

"Does spiral support make peeing with a chip in painless?"

In an entry published in January 2020, a prospective customer asked about discomfort with a curved-tail semi-long ceramic chip. Mr. Okada distinguished that tail from spiral support: he said enough pressure on the tail could also stop urine.

The customer confirmed payment, but the diary does not record their experience in use. Mr. Okada cautioned that no reported pain from chips straddling a sphincter did not guarantee painless use.

https://ok-lab.hatenablog.com/entry/2020/01/25/150127

"Could a stent stop my chip coming out when peeing?"

In an entry published in October 2020, a customer sought a stent (Mr. Okada's experimental metal spring device) for repeated expulsion. Mr. Okada declined to sell it before further testing for urethral safety and unexpected problems.

The diary does not record whether that customer subsequently bought an alternative. Mr. Okada instead suggested a short or short twisted chip with a spiral support accessory.
