Usually, patients with neurourologic problems express their LUTS very subjectively, and the way of showing their LUTS can be different according to their personal and social characteristics. Therefore, it is necessary to objectify subjective symptoms, and various symptom questionnaires have been using to evaluate the patient’s LUTS. The present issue of the International Neurourology Journal (INJ) introduces the Korean version of the Wisconsin Stone Quality of Life Questionnaire and Urgency and Overactive Bladder Questionnaire after linguistic validation for clinical use [1,2]. There are many studies about the importance of microbiome on human health, and the role has been expanded. However, there is an important issue before we think about the clinical application in neurourology. Microbiome found in urine can be affected by the urine collection methods. The study by Pohl et al. [3] reported the difference of urinary microbiome according to the urine collection method in healthy men and women. Thus, further studies to develop a standard urine collection method are necessary for the clinical application of microbiome in the neurourologic field.

Moreover, in this issue of the INJ, 2 review articles give additional and useful information of underactive bladder (UAB) and benign prostatic hyperplasia (BPH) as well as new insight for the neurourology. Overview of UAB and robotic surgery of BPH increase knowledge of the disease entities and therapeutic approach [4,5].
