Abstract
An indwelling endourethral drainage catheter includes a tubular distal portion and a spiral proximal portion. A central lumen extends along substantially the entire length of the catheter. The spiral proximal portion defines an outer spiral channel in fluid communication with the central lumen. The distal end of the catheter is anchored externally so that the catheter is held against advancement into or out of the urethra. In certain methods, the diameter of the spiral proximal portion may be changed to address obstructions within the urethra or facilitate navigation of the catheter along the urethra.
