[Spontaneous resolution of urodynamically proven sphincter lesion following surgery for prostatic hyperplasia].

Assuming that post-prostatectomy incontinence frequently resolves to various extents, forty patients from a background material of 105 consecutively referred patients with this complaint were reexamined three to 106 months (median 55 months) after first examination. During the time interval between first examination and the revisit only four patients had some improvement of their incontinence. Eleven patients were evaluated urodynamically at both occasions showing no change in MUCP (maximal urethral closure pressure) or other urodynamic parameters. Consequently we could not confirm the dogma that sphincter lesion due to prostate surgery may gradually resolve. Our investigation indicates a poor continence prognosis in patients incontinent after transurethral or transvesical surgery of the prostate and that there therefore should be a more active treatment attitude. The patients should be offered an operation after evaluation of their incontinence, when a sphincter lesion is first diagnosed.
