Thirty-nine patients were evaluated after retropubic prostatectomy, by
urodynamic studies. They were divided into three groups depending upo
n the degree of urinary continence. A statistically significant differ
ence was found between different groups in mean functional profile len
gth and maximal urethral closure pressure. Differences in age, previou
s prostatic surgery, tumour extension, or preservation of the neurobun
dles did not have any significant influence on recovery of continence.
