Evaluation of Urodynamic indices and distribution curve of indices obtained from the findings of the urodynamic center of Ali Ebn Abitaleb Hospital of Zahedan University of Medical Sciences from the beginning of establishment to 2020

In this descriptive study, we extracted all the information of patients over 18 years of age entered in the urodynamic system of the USD Center of Ali Ibn Abi Talib Hospital, Zahedan University of Medical Sciences separately.

The average Pdet before voiding (detrusor muscle pressure before diuresis) was equal to 23.81 cm of water. The average Pdet Qmax (highest detrusor muscle pressure during qmax) was also equal to 31.13 cm of water. The average Qmax (highest intensity of urine flow) was 20.51 ml/s. The average bladder contractility index in the urodynamic test was equal to 136.05 cm of water and there was a significant difference between the average Pdet before voiding, Pdet Qmax, Qmax and bladder contractility index according to age and gender. The average First Sensation Volume was 146.9 ml, First Desire to Void Volume was 281.1 ml, and Strong Desire to Void Volume was 305.1 ml, respectively. Age had a significant relationship with First Desire to Void Volume and Strong Desire to Void Volume. However, there was no relationship between gender and these 3 variables. The average Cystometeric Capacity (the total volume of the bladder in the urodynamic test) in the urodynamic test was 361.78 ml. Age had a positive correlation with Cystometeric Capacity; However, there was no correlation between gender and total bladder volume.
