[Pay attention to lower urinary tract dysfunction and the clinical application of urodynamic studies in children].

Lower urinary tract dysfunction (LUTD) is the dysfunction of bladder and urethra during bladder filling and voiding phase. There are two general categories: neurogenic and non-neurogenic. It can cause upper urinary tract damage if left untreated. Urodynamic study (UDS) can objectively detect the function of detrusor and sphincter of urethra as well as predict the damage of LUTD to upper urinary tract. However, the development of UDS for children in China has not been popularized, which affects the accurate diagnosis and the treatment of LUTD. This article reviewed the importance of paying attention to LUTD and promoting the clinical application of UDS in children, so as to improve the diagnosis and treatment of LUTD in children.
