TO THE EDITOR:— Not only do patients at home find difficulty in cleaning urinal tubes in cases of suprapubic fistulas of the incrustations caused by phosphates, but I have noticed also in hospitals the same lack of proper procedure. The urinals never get properly clear. The tubes used for the drainage of the urine are boiled sometimes but the whitish deposits remain. I saw Pezzer catheters ready to be inserted with the grayish stonelike crystals in their heads. The deposits are not easy to remove mechanically; rubbing and scratching has some effect but take time and do not give satisfactory results. There is a simple means to get excellent results: Catheters are put into a 5 per cent solution of muriatic acid; urinals, india rubber tubes, connecting glass tubes are treated with an 8 to 10 per cent solution and in a short time they are cleaned and clear.
