Evaluation of detrusor activity during micturition in patients with benign prostatic enlargement with a clinical nomogram.
OBJECTIVE
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.


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.
