Bladder capacity is an important factor in the diagnosis and treatment of individuals with voiding dysfunction. In contrast, self-reported quantity of normal maximal voided volume in healthy young is few.
The purpose of this study was to define the quantity of normal maximal voided volume in healthy young. This prospective study was carried out in 72 students aged 17–24 years who did not have clinical voiding dysfunction undergoing nursing education in a University in Sakarya, Turkey. The study was conducted in December 2011. Healthy young were recruited to determine the quantity of the normal maximal voided volume. The maximal voided volume was determined in all subjects using a frequency volume chart with a voiding observation.
In our study, the normal maximal voided volume (mL) for females was 413·3 ± 167.9 and the normal maximal voided volume (mL) for male was 589·2 ± 108·5.
These formulas may be useful for the diagnosis of abnormal bladder capacity and the evaluation of voiding dysfunction in young. This research may be the source for studies that could include climate, cultures and different age groups.
