Located in Kokurakita Ward, Kitakyushu City, Fukuoka Prefecture, Medical Corporation Koshukai Kawai Nephrology & Urology Clinic specializes in nephrology and urology. In April 2024, a nephrology specialist joined the practice, adding nephrology services to the existing urology care. The clinic provides outpatient treatment for kidney diseases including IgA nephropathy, nephrotic syndrome, diabetic nephropathy, nephrosclerosis, polycystic kidney disease, and pre-dialysis chronic kidney disease. In urology, it is designated as a prostate cancer screening facility and actively performs prostate biopsies. The clinic is well-equipped for dialysis treatment, with 46 dialysis beds and approximately 150 hemodialysis outpatients. Treatment options include hemodialysis, peritoneal dialysis (CAPD), and online HDF (hemodiafiltration), with evening dialysis also available. A pickup service is offered for patients who have difficulty traveling to the clinic. Examination rooms are designed with privacy in mind, and the facility includes parking and barrier-free access. English-speaking service is available. Clinic hours are 9:00 AM to 6:30 PM on weekdays (with a lunch break), closed on Sundays, public holidays, year-end/New Year, and Obon. Patients experiencing symptoms such as hematuria, proteinuria, leg edema, frequent urination, dysuria, or voiding dysfunction are welcome to consult the clinic whether they need nephrology or urology care.
