Purpose:
We investigated the accuracy of analysis of detrusor contraction during micturition with a simple to use pressure-flow nomogram (linear passive urethral resistance relation). The computer derived maximum detrusor contraction parameter was used as a reference. The correlation with bladder emptying capability was used as a control.
Materials And Methods:
Advanced pressure-flow analysis was performed in 224 elderly men with lower urinary tract symptoms.
Results:
All patients with a contraction classified as normal on the nomogram had good maximum detrusor contractions. However, 50% of the patients with a weak classification on the nomogram showed good maximum detrusor contractions.
Conclusions:
The nomogram is useful in the selection of patients with a good detrusor contraction.
