Description

We studied on subjective and objective findings of 69 patients with lumbar spinal canal stenosis. Of the patients 51 (73.9%) had not only orthopedical symptoms but also urological complaints of mostly emptying disorders such as protracted and retardated dysuria and urinary retention, 14 (20.3%) no urological symptom and four (5.8%) urological complaint alone. Cystometrographic findings investigated from all of the patients revealed normoactive detrusor in 34 (49.3%) of them, underative or acontractile detrusor in 28 (40.6%) and oveactive detrusor 7 (10.1%). Eighteen of the patients underwent a surgical treatment for the lumbar spinal canal stenosis. All of seven patients with normoactive detrusor had a good micturition and four of nine with underactive or acontractile detrusor and one of two with overactive detrusor required clean intermittent catheterization (CIC) even after the surgeries. Pre and post surgical urodynamic studies demonstrated that the seven patients resulted in normoactive in four and overactive in three, the nine underactive in six and overactive in three and the two overactive and underactive in one, respectively. It was suggested from the results that the bladder of a patient with limbar spinal canal stenosis could become more irritable state after the surgery than before the therapy.
