Purpose : Tethered cord syndrome is characterized by progressive motor and sensory disturbances in lower extremities, foot deformities caused by a pathologic fixation of spinal cord resulting in excessive stretching of the spinal cord. It is also frequently associated with urological symptoms include urinary frequency, incontinence, enuresis, urgency and recurrent urinary tract infection. Because there is few report in the literature about urological manifestations of theterd cord syndrome, we conducted a retrospective study on the patients diagnosed as tethered cord syndrome to delineate the characteristics of urologic manifestations in tethered cord syndrome and to establish the policy to evaluate patients who is suspected of tethered cord syndrome. Method : A retrospective study was conducted by reviewing the medical records of nine patients who was diagnosed as tethered cord syndrome from November 1991 to July 1996 in Yeungnam University Hospital. Result : 1) The age distribution of nine patients was as follows; 5 patients were under 2 years, 1 case from 2 to 6 years and 3 cases from 6 to 10 years. 2) Of 9 patients 6 had voiding frequency, urinary incontinence, enuresis, urgency and loss of micturation sense. Radiologic urodynamic studies revealed neurogenic bladder in 5 patients, hydronephrosis and hydroureter in 3, vesicoureteral reflux in 3. 3) Of 6 patients with urological abnormal manifestations 4 underwent spinal cord surgery (detethering). In spite of surgical intervention, the urological manifestations improved in only one patient.
Conclusion : Urological abnormalities were common in tethered cord syndrome. Abnormal laboratory findings including urodynamic study were found even before the onset of urological symptoms. We have to concern tethered cord syndrome as one of common causes of voiding frequency and enuresis and to evaluate urological abnormalities as thetered cord syndrome is diagnosed.
Key words: Tethered cord syndrome | Urological manifestations
