1. Patients with urinary retention or bladder outlet obstruction
If drug therapy is ineffective and there is no indication for surgical treatment, patients with urinary retention who need temporary relief or long-term drainage are required.
To alleviate the suffering of dying patients; other non-invasive measures such as the use of drugs, urine pads, etc. can not be alleviated and patients can not accept the use of external diapirs.
3. Accurate monitoring of urine output
Frequent monitoring of urine output, such as critically ill patients.
4. The patient is unable or unwilling to collect urine
Surgical patients with longer operative time under general anesthesia or spinal anesthesia; perioperative patients requiring urinary or gynaecological surgery.
