Impact of patient position on cystometric parameters in pediatric patients with neurogenic bladder: A prospective study.

AIMS

Urodynamic studies (UDSs) play a crucial role in evaluating lower urinary tract function in pediatric patients with neurogenic bladder. However, the influence of patient position on urodynamic parameters in this population remains understudied. This study aims to investigate the effect of patient position on urodynamic results in children with neurogenic bladder.

METHODS

A prospective study was conducted with 50 pediatric patients diagnosed with neurogenic bladder. Urodynamic recordings were obtained during a single session, with the first two fillings in the supine position and the third filling in the sitting position. Urodynamic parameters assessed included detrusor overactivity (DO), maximum detrusor pressure (MDP), cystometric bladder capacity (CBC), compliance (C), detrusor leak point pressure (DLPP), and bladder volume at the moment of incontinence (DLPV).

RESULTS

Patient position did not significantly influence CBC, DO, C, and DLPV (p > 0.05). However, there were significant differences in MDP and DLPP between the supine and sitting positions (p < 0.05), with higher values observed in the supine position.

CONCLUSIONS

These findings highlight the importance of considering the patient's position when interpreting urodynamic results and making treatment decisions for children with neurogenic bladder. The higher MDP and DLPP values in the supine position may have clinical implications for assessing upper urinary tract integrity and treatment planning. However, further research is needed to understand the underlying mechanisms and generalize these findings to broader patient populations.
