A MODIFIED FOLEY CATHETER LESTER PERSKY From the Department of Surgery, Urological Service, Western Reserve University and the University Hospitals, Cleveland, Ohio
All urologists at various times have felt that son1e modification of current equipment was indicated. The nature of our specialty has induced the innumerable variations in the tools of our trade and has captivated the imagination of our colleagues. The tremendous worth of the balloon catheter introduced and popularized by Foley needs no ainplification to any urologists. Nevertheless, at times, even with an article so universally utilized and appreciated as the retention catheter, variations and modifications seem warranted. Therefore, in an attempt to possibly achieve improved and more dependent drainage and, at the same ti1ne, to afford minimal mucosal contact with the security of adequate fixation, we devised with help* a slightly different catheter (see illustration). The short tip has prevented the occasional obstruction due to the knuckling over of the longer tips of other more conventional catheters and, in conjunction with the disc-like balloon, has afforded the most dependent type of drainage without the insecurity which straight tubes that are taped in place engender. The balloon of our catheter is filled by only 3 ml. distending fluid and attains a flattened, discoid appearance. Even though the openings for drainage are in close proximity, we have not had failures due to encroachment upon them by the distended balloon. We have successfully used these catheters in nephrostomies, suprapubic cystostomies, closure of vesicovaginal fistulas and a variety of other Accepted for publication October 18, 1966. Read at annual meeting of North Central Section, American Urological Association, Inc., Chicago, Illinois, September 28-0ctober 1, 1966. * Mr. Howard Doerr, formerly of Akron Foley Catheter Co.
urological disorders. They have been especially useful in affording a means of achieving the closure of persistent suprapubic fistulas following transvesical prostatectomy. However, their greatest use has been in pediatrics where the short tip has been repeatedly invaluable. We hope that the continued use of our catheter will afford a worthwhile addition to urologists elsewhere and that further applications will be found. A
