Clinical Evaluation of Catheter-induced Urinary Tract Infection by Sterile Closed Drainage / 대한비뇨기과학회지

In 57 hospitalized patients with temporary closed sterile urinary-catheter drainage, incidence of acquired bacteriuria was evaluated by culture, colony count, drug sensitivity and the following results were obtained. 1. Incidence of infection was 0% within 3 days, 18.2%o within 5 days, 41.7% within 7 days, 60.9%0 after 7 days. 2. Of 117 bacterial strains isolated by culture of urine 82.1%o was gram negative bacteria and 17.1%o was gram positive. The frequency of isolated organisms were as followings: Escherichia coli ............. 44.4%, Pseudomonas aeruginosa ............. 19.7%, Staphylococci ............. 14.5%, Caliform bacilli ............. 9.5%, Proteus ............. 6.8%, Streptococci ............. 4.2%, Yeast ............. 0.9%. 3. Most organisms were highly resistant to any of antibiotics which were Kanamycin, Gentamicin, Ampicillin, Streptomycin, Tetracycline, Cephoran, Geopen, Amiktam. 4. Closed sterile drainage system was much effective in delaying bacteriuria than open drainage system in comparison with 70.8% of bacteriuria within the first 3 days of open catheter drainage demonstrated in previous report.

Modified Pull through urethroplasty(Netto procedure) in posterior urethral stricture / 대한비뇨기과학회지

To avoid the ball valving obstruction and the interference with ejaculatory process by intussuscepted urethra in Badenoch`s pull through operation, the modified Badenoch operation(Netto procedure) was used in five patients with the post traumatic posterior urethral stricture. The technique was that bulbous urethra was intussuscepted into prostatic tissue only about 5-10mm and the superficial external layer of the bulbous urethra was sutured to superficial external surface of the prostate with 4-6 interrupted sutures at the point of intussusception. Of the 5 patients, 4 have and had satisfactory results and one with dilation.
