[Our experience of treating urological infections with a single dose of gentamycin]

31 patients with a urological infection caused by a bacterial strain susceptible to gentamycin were treated by a single injection of 240 mg of gentamycin. 11 patients (35.5%) fully recovered, the infection was eliminated and the clinical symptoms and signs disappeared. Better results were achieved in patients with infection of the lower urinary tract without pyelonephritis, 7 out of 15 patients (46%) recovered. Out of 16 patients with pyelonephritis only 4 were cured (25%). Of 10 patients with nephrolithiasis only 1 was cured, in the remaining 9 patients the treatment was without effect. In the group of patients who recovered the patients with E. coli infection prevailed while in the group of unsuccessfully treated patients other bacteria prevailed. No side effects were found. The conclusion is that the treatment with a single gentamycin dose could be applied successfully in patients with an infection of the lower urinary tract without pyelonephritis, morphologic changes in the urinary system or nephrolithiasis.
