OJP084: Ureterocele / Tube With Contrast Medium
'Tube With Contrast Medium' was self released in December 2025, one year and eight months after his previous album 'Left Renal Agenesis'. The title refers to a kidney examination in which a tube is inserted through the urethra and contrast medium is injected to confirm whether both kidneys are present. That test revealed that he has only one kidney, and the remaining kidney had enlarged to compensate.
This album was created from a desire to build tracks out of sounds that represented contrast medium being injected, blood traveling through blood vessels, and how the outside world might sound if someone were small enough to be inside the bladder. It also aims to express the small, quiet feelings carried during those tests.
In the title track, the opening koto sound was inspired by an X-ray image, where part of the organs looked like cherry blossoms. The blast beat reflects the speed of the contrast medium rushing into the body. “Gradient Coil Noise” is Ureterocele’s interpretation of the sound heard during an MRI scan. The final three tracks move into beat-driven loop pieces, including a return of the koto sample as a small gesture of respect to listeners who enjoy Japanese culture.
Ureterocele is a Tokyo based dark experimental solo project that began in 2024. The music is created in a DAW with programmed parts and multiple layers of effects processing, while the bass is recorded as fully improvised takes to bring live variation into the tracks. The artist name comes from a medical term related to a congenital condition. Ureterocele has also donated a portion of Bandcamp proceeds to medical institutions in Japan. Influences include Nurse With Wound and The Pop Group, as well as online visual aesthetics such as mallsoft, liminal space, and weirdcore.
Digital release on the 20th of February 2026.
