Urethral bougies are medicated pencils, specially adapted for the application of medicinal substances to the urethra. Their preparation differs in no essential particulars from that of ordinary suppositories, but they differ in shape, being like a pointed rod. Urethral bougies may have either a gelatin or cacao-butter basis, and be of any length up to 15 centimetres (6 inches). Usually they are employed 6.5 centimetres (2 ½ inches) or 13 centimetres (5 inches) long, and these weigh 1 gramme (15 grains) and 2 ½ grammes (40 grains), and have about the diameter of a No. 8 and No. 9 catheter respectively.
The basis should be melted at a low temperature, and the active ingredients, in fine powder, added with constant stirring, and when the mixture is about to set to a solid mass it should be poured down a warmed glass rod into suitable moulds. The oil of theobroma may be replaced, if desired, by one of the following mixtures:—(1) Oil of theobroma, 90; wool fat, 10. Melt together, and stir until cold. (2) Oil of theobroma, 50; hydrous wool fat, 25; white beeswax, 25. Melt together and stir until cold.
