Abstract     The most valuable laboratory investigation in order to diagnose a urinary tract infection and proceed with the treatment is a quantitative culture of urine specimen. For this kind of investigation it is necessary to obtain a urine sample that will reflect the character of the urine present in the bladder, with same species of bacteria in equal concentrarion. The midstream technique is recommended for adults and the children who are capable of bladder control. With infants and small children incapable of voiding upon command, the midstream technique for obtaining urine sample is possible and reliable only by waiting for the act of micturirion. It is however very time-consuming and therefore unuseful in clinical practice. In these patients urine is mostly obtained by invasive procedures, urine bags and collectors. The two invasive methods for urine sampling give appropriate specimen but they are quite complex and painful. Both also carry considerable risk of complications. In our opinion they are not suitable for routine use, but do come in consideration in exceptional cases. It is well recognized that the use of adhesive urine bags results in a too high proportion of false positive urine cultwes to be used in clinical practice. It can lead to an erroneous treatment of children who do not have a urinary tract infection. Kenda designed a plastic, disposable urine collector, which separates the final portion of the voided urine in a collecting tube. This urine is used for culture. The rest of the urine is collected in a second chamber and is discarded. The collector is meant to be used instead of the urine bag. Its handling is simple and its false positive rate is similar to that obtained with the "midstream technique". (Abstract truncated at 2000 characters).
