“…None of the previously mentioned methods (CC, TUBC or SPA) meet all of these criteria and there is an ongoing debate over the preferred technique. 11 The literature has not established an ideal method of urine collection for diagnosing UTIs, and international guidelines vary.

“…An optimal urine sampling method for paediatric urine culture should have high sensitivity and specificity, low contamination rate and should be noninvasive and quick.

Aim Urinary tract infection is a common cause of paediatric morbidity. However, there is no consensus on the default method for urine culture collection in children. This study aimed to examine the contamination rates of different urine collection methods. Methods This was a retrospective cohort study in a paediatric emergency department. Data were collected from electronic health records on all children whose urine culture samples were obtained in the paediatric emergency department between March 2018 and March 2019. Different methods of urine collection included the midstream (MS) method, clean catch (CC), transurethral bladder catheterisation and suprapubic aspiration. Contamination rates and positive urine culture rates were calculated and compared for sex, age, and collection method. Results Urine culture samples were collected from 1507 children. There were 284 (18.8%) cultures that were positive with significant growth and 52 (3.5%) that were defined as ‘contaminated’. The contamination rates for the midstream method in toilet‐trained children were 1.6% (10/609), 4.9% (17/348) for CC in pre‐continent children, 4.9% (25/515) for transurethral bladder catheterisation and 0% (0/35) (P = 0.006) for suprapubic aspiration. There was no significant difference in contamination rates of urine cultures collected by CC and catheterisation in the compared groups. The rates of positive cultures in the subgroup of children with high suspicion for Urinary tract infection were also found to be similar. Conclusions Our study shows that CC is non‐inferior to catheterisation for collecting urine cultures in young children.

“…There are two methods to obtain a urine specimen: non-invasive (for example, urine bags, pads, or clean catch) [43] and invasive (for example, catheter or SPA) techniques [44]. Spontaneous voiding is the main non-invasive technique, such as commonly used in cases of dysfunctional voiding [45] although other strategies may be used in children who cannot yet control their voiding, such as the use of bag urine [46].…”

Aims: intended to deepen our knowledge to date regarding parasites that might found in urine sediment as consequences of vaginal or fecal contamination during voiding Discussion: Urine in the bladder is a sterile waste product composed of water soluble nitrogen products. But during voiding, the passage of the urine through lower/outer portion of the urinary tract might come across normal microbiota which function in maintaining the urothelial integrity and preventing urinary tract infection (UTI), as well as promoting local immune function. Parasites and parasitic ova may be seen in urinary sediments as a result of fecal or vaginal contamination. Identification of parasites in centrifuged deposits of urine sediment is a relatively rare occurrence in clinical practice but still must be considered carefully, whether as a consequence of contamination or definite causes of infection. Two of the common parasite found in urine sediment are Trichomonas vaginalis and Enterobius vermicularis. Urine collection procedure must be explained briefly to the patient along with appropriate informed consent prior obtaining the sample. Conclusion: The possibility of parasites being found in urine sediment remain to happen. An in-depth analysis needs to be carried out to determine whether this occurs due to vaginal or rectal contamination or whether it is due to a definitive infection occurring in the urinary tract.
