Difference between urostomy and suprapubic catheter?

A urostomy is a surgical procedure that creates an opening (stoma) in the abdomen to divert urine from the bladder to an external pouch, typically performed when the bladder is removed or non-functional. In contrast, a suprapubic catheter is a flexible tube inserted through the abdominal wall directly into the bladder to drain urine, often used for patients who cannot urinate normally. While both manage urinary function, a urostomy involves a permanent diversion, whereas a suprapubic catheter can be temporary or long-term, depending on the patient's needs.
