There are controversies regarding pre-operative routine investigations in ambulatory operations in the paediatric age group. Routinely, patients’ packed cell volume (PCV), and genotype were the investigations done for children before surgery, but somewhere along the line, the anaesthesiologists now demand for pre-operative routine urinalysis in children going for ambulatory operations to help detect occult urinary tract diseases. The aim and objectives was to find out the benefits of doing routine preoperative urinalysis and whether it was really necessary in children undergoing ambulatory operations in Lagos, Nigeria”? It was a one year prospective study, carried out from the 1st of September, 2018 to the 31st of August, 2019 in the Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria. Eighty four children, between the ages of 0 - 12 years, slated for ambulatory operations were mandated to do routine pre-operative urinalysis, routine packed cell volume estimation, and genotype studies. All the children were operated under general anaesthesia. Eighty four children were recruited, comprising of 72 (85.7%) males and 12 (14.3%) females with a male: female ratio of 6:1. The patients’ age ranged from 0 to 12 years with a mean age of 5 ± 3 STD. An average, minimum and maximum weights of 18.9kg, 5.0kg, and 44.0kg respectively were recorded, while the average PCV was 34.4%, with a minimum of 26.9% and maximum of 48.0%. The results of urinalysis were normal in 82.1% and abnormal in about 17.9% participants. In the abnormal group, (proteinuria trace = 7, leucocytes = 4, nitrites = 2, proteins + nitrites = 1, and urobilirubin = 1). All study subjects underwent the procedures successfully with no record of cancellation of any procedure as a result of an abnormal urine finding. We conclude that routine pre-operative urinalysis should be done on all our paediatric ambulatory surgery patients with a view to detecting any abnormalities that may require a follow-up.
