 note = {A double-J (D-J) catheter is a kind of artificial ureter which has the character of not contacting with skin. Among 21 cases with indwelling all-silicone D-J catheters, the catheter was inserted during operation in 20 cases, and indwelt transurethrally for treatment of hydronephrosis in the remaining one case. At the time of removal of the D-J catheter, bacteria were found in all 18 cases on the bilateral edges (renal pelvis and urinary bladder) of the catheter. The bacteria isolated from the bilateral edges were the same in 15 cases, but different in 2 cases. Bacteria were found only on the bladder edge in one case. Two or more species of bacteria were found in 7 cases, and 18 of 26 isolates were of cocci. Bacteria were isolated from cultivated urine samples only in 4 (20%) of 20 cases: all of the 4 isolates consisted of single species, 3 of which were of a yeast-like fungi, and the remaining isolate was a coccus. This suggests that bacteria, even though not found in urine, may be present in the catheter and can cause urinary tract infection at any time. The white blood cell count in the urine was 10 or less in a 400X visual field in 16 out of the 21 cases: no case with a count of 30 or more was found. The antibacterial treatment mainly employed was drip infusion of cephem drugs, usually until 7 days after the operation, followed by oral administration mainly of new quinolones.},
