[Study on the detection of bacterial infection in tubeless ureterocutaneostomy].
The presence of bacteria at the renal pelvis and the methods of their detection were studied in 11 patients with catheter-free cutaneous ureterostomy (tubeless ureterocutaneostomy). These patients had had total radical cystectomy due to bladder carcinoma. Of these, 5 patients had single-sided stoma with 9 kidney-ureter units and 6 patients had bilateral stoma with 10 units, excluding 2 ureters because of indwelling catheters. The urine obtained both from the renal pelvis with a single lumen catheter and from the pouch were used in the bacterial culture test and urinalysis. The aseptic swab after touching the skin around the stoma was also cultured for bacteria. Of 19 kidney-ureter units, 9 (47%) were found to have bacteria in urine obtained from catheterization. However, only 2 units (11%) were observed to be accompanied with pyuria. In this method, the rate of bacterial appearance was higher in single-sided stomas than in bilateral ones. There was no statistical correlation between the presence of hydronephrosis and the rate of bacterial appearance. In conclusion, the method of single lumen catheterization might be of great use for analysis of urinary tract infections in patients with such conditions.
