[An 89-year-old man who underwent percutaneous peritoneal dialysis catheter placement and had peritoneal dialysis introduced].

The number of elderly patients requiring dialysis is continuously increasing. In Japan, many patients undergo hemodialysis; however, it has been associated with huge stress-mainly on the cardiovascular system-and requires frequent hospital visits. Conversely, peritoneal dialysis is much less invasive with a much lower frequency of hospital visits than that of hemodialysis; therefore, it is suitable for elderly patients. In addition, peritoneal dialysis, which originally had a high affinity for home care, has become more useful for elderly patients with renal failure thanks to the recent introduction of a cloud-based remote monitoring system at home. We performed percutaneous placement of a peritoneal dialysis catheter to reduce physical invasiveness and initiate peritoneal dialysis. The Barthel Index before hospitalization was 0 but increased to 65 at discharge. Further technology advancements in peritoneal dialysis are expected in the future. The cloud-based remote monitoring system is also expected to maintain or increase activities of daily living and the quality of life in elderly patients with renal failure with decreased activities of daily living.
