• The technology described in this briefing is the U‑Drain. It is used for people with a long-term urinary catheter, urinary sheath, urostomy pouch or who have automated peritoneal dialysis, who need night drainage of urine or dialysis fluid.

  • The innovative aspects are that it is a drainage system that is permanently installed in the user's home. It is used overnight for draining waste fluid directly into the existing soil pipe.

  • The intended place in therapy would be as an alternative to overnight drainage of urine or waste fluid into a night drainage bag in people with long-term urinary catheters, urinary sheaths, urostomy pouches or those having overnight automated peritoneal dialysis.

  • No publicly available evidence on the U‑Drain system was found. Although conventional clinical-effectiveness studies would not be expected on relatively simple technologies such as U‑Drain, evidence of impact on quality of life would be useful.

  • The cost of the U‑Drain device includes the installation at £350 and an annual cost of £130 for urine drainage consumables or £500 per year for automated peritoneal drainage consumables (exclusive of VAT). In usual care, the cost of night drainage bags is between about £13 and £91 per year depending on type, and the cost of peritoneal dialysis waste drainage bags is around £800 per year. Apart from equipment costs, the resource impact would be similar to standard care.
