Background : The purpose of this study was to determine whether cleansing the perineum and urethral meatus and using midstream urine affect the rate of bacterial contamination of urine specimens, and to determine the optimum urine collection method. We studied 41 asymptomatic healthy nursing school students. Women who were menstruating were not excluded from this study. Method : The first and midstream urine samples were collected during consecutive urinationsby each woman. The first sample was not a clean-catch specimen, and the second one was a clean-catch specimen. Both specimens were studied by urinalysis and bacterial culture with standard methods. Results : 41 women met the study criteria and 39 successfully completed the study. None of the urine cultures were positive. 68.3% of the non clean-catch first urine cultures, 53.7% of the non clean-catch midstream cultures, 33.3% of the first clean-catch urine culteres and 30.8% of the midstream clean-catch urine were found to be contaminated. There was a significant difference in the bacterial contamination rates between the first and midstream urine, and the clean-catch and non clean-catch urine(p=0.035, p =0.001 respectively). On urinalysis, 7.3% of the non clean-catch first urine, 7.3% of the non clean-catch midstream urine, 2.6% of the clean-catch first urine and 2.6% of clean-catch midstream urine were found to be above grade 2. Conclusions : According to our results, the bacterial contamination rate was the lowest in midstream and clean catch urine specimens. Threrfore it is recommended that the midstream clean-catch technique is the standard practice for collecting urine specimens for bacterial culture in women.

Utilizing Foley catheter in therapy of inpatient cause bacteriuria and urinary tract infection that leads to first ranked factor's in hospital infection (nosocomial infection). To protect the patient from such infections, emphasis should be placed on catheterization technique and management of the closed drainage system, this reducing the chances of introducing organisms. This study has been done at Intensive Care Unit of A and B hospitals from May-Oct. 1978 on 20 male and 18 female adult patients. Each patient was screened and found to have nonbacteriuria in clean catch specimen before catheterization. Clean catch specimen via foley catheter were obtained after 48 hours and 96 hours from catheterization. The findings are as follows: A. The occurrence of bacteriuria in patients according to duration of indwelling catheter. 1 213.9% of the patient showed evidence of bacteriuria 48h post catheterization specimen, while 57.9% of the patient showed evidence of bacteriuria 96h post catheterization specimen. 2 25% of male patients had infection 48h post catheterization and 45% displayed bacteriuria post catheterization. 33％ of female patients displayed infection 48h post catheterization and 72.2% having infection 96h post catheterization. Statistically there were significant differences between female patients and the duration of insertion. (P < 0.025) B. The occurrence of bacteriuria with the administration of bacteriuria with the ad-ministration of antibiotic in 24 patients was in 41,7%. The occurrence of bacteriuria without the administration of antibiotic in 14 patients was in 92.3%. Statistically there were very significant difference between the administration of the antibiotis and bacteriuria. (P < 0.005) C. Studies were done according to the consciousness level of the patients, 71.4% of those patient who displayed mental disorder developed bacteriuria, while 30.0% of those patient who displayed non mental disorder developed bacteriuria.
