Urodynamic evaluation of urinary incontinence following radical prostatectomy: our experience.

Thirty-four patients after retropubic radical prostatectomy, were evaluated with urodynamic studies. Patients were divided in three groups depending on the degree of urinary continence. A statistically significant difference was found between different groups for the mean functional profile length and maximal urethral closure pressure. Detrusor instability was detected in 11 patients with moderate incontinence and in 1 patient with severe incontinence. Neither differences of age, previous prostatic surgery, tumour extension, nor preservation of the neurovascular bundles had any significant influence on recovery of continence.
