,'\ nurnber of methods have been used to retaiu eatheters. 1 · 2 • :i This retainer is not new in principle. H owevc~r, in institutions where a large number of nepbrostomy, pyelostomy or ureterostomy catheters am in use, thi::; retai11er can be and inexpensively made a technician. It i::; u::;ed for ,Yhicitle-tip-like catheters which at the Paraplegic Center are prefeffed to the self-retaining catheters for nephrostomies, pyelostomies or ureterostomies. It can also be used for c,Uprapubic whistle-tip catheters. 1Ve have found it easier to use a mbher retainer ratber than plastic since it molds bett(,r to the particular contour of the body. Hec1a11gular shaped retai11ers have been used rather than round hut any shape can be nrnd.e.

Fm. 3. Setup ready for lighting of hot patch. Here wooden plates are used
Figure 3 shows the apparatus, using detachable wooden plates, ready for lighting of the hot patch. Since it is somewhat cumbersome to handle the individual parts, the apparatus shown in figure 4, A was developed. This consists of the integral parts being welded to the C clamps. A groove has been cut into the metal base % inches wide. Five metal plates have been made available in the center of which have been drilled holes measuring % inch, ½ 6 inch, 7~ inch, :!-16 inch, and % inch respectively. These plates are adequate for the variety of sizes of catheters that will be used. To the desired size of metal plate are fixed the cold patch, catheter end and hot patch. The plate in turn is slipped through the groove depicted in figure 4, A.. The entire system is tightened and figure 4, B shows the final setup ready for lighting of the hot patch. After cooling, the retainer is sterilized and ready for use. Figure 5 demonstrates our method of using elastoplast and ties in order to hold the retainer in a fixed position. A split 4 by 4 inch gauze pad is placed between the skin and rubber retainer and also between the retainer and the elastoplast. The gauze may be changed daily or as required; and the catheter and retainer are

changed weekly. If infrequent dressings are performed, elastoplast strips can be placed across both sides of the retainer and onto the skin. This latter procedure depends on the skin's tolerance of elastoplast. At surgery, nephrostomy catheters are held in position with wire sutures to the skin until the time when the wound is healed and a good nephrostomy channel has been formed. Only then is the retainer used as described. For additional safety, some patients, especially with bilateral nephrostomies, prefer to use, in addition, a 6 inch elastic belt with holes to permit the exit of the catheters. This "girdle" reinforces the retainers and is also excellent as a support if postoperative muscle weakness is present (fig. 6). SUMMARY
A simple, inexpensive method of making nephrostomy, pyelostomy, ureterostomy or suprapubic retainers has been described. A very satisfactory method of keeping the "catheter retainer" in place is presented.
