Suprapubic urinary catheters designed to drain urine from the bladder into an external collection device. These catheters consist of a flexible tube, typically ending in a tightly curled distal tip (i.e., \'pigtail\'); at the proximal end, the drainage lumen is attached to an external collection bag. Suprapubic urinary catheters are mostly used for short- and long-term continuous catheterization in patients with urethral obstruction or erosion (e.g., patients that are critically ill or who have severe disabilities, those requiring postsurgical or traumatic injury treatment).
