Risk factors of difficult intravenous access and catheter failure in the urology ward: A prospective observational study.

Background: Patients in the urology ward often require peripheral intravenous catheters for cancer chemotherapy, antibiotics to treat urinary tract infections, surgery, and other treatments. Moreover, as the elderly population within urology has a high incidence of cancer, many patients also have fragile vasculature. Proper intravenous catheter insertion and management are crucial in such cases.
