Urologic symptoms (Ux) are sometimes the only indication for neurosurgical intervention but the benefit of this is still unclear. Herein, we describe the urologic outcomes of tethered cord release in children with OSD. METHODS Records of patients aged 0-18 years undergoing primary tethered cord release for OSD at our institution were reviewed (2000-2010). Patients with open spinal defects, lipomyelomeningoceles, secondary tethering, spinal trauma and tumors were excluded. MRI pathology, indications for surgery and the presence of lumbar cutaneous stigmata (CS) were correlated with Ux before and after surgery. Ux included subjective urinary symptoms (eg. frequency, urgency), incontinence, constipation, urinary infections and need for intermittent catheterization. Clinical history, renal ultrasonography and urodynamics (UDS) were assessed. RESULTS 216 patients underwent untethering and 55 met inclusion criteria, with median follow up of 4.7 years (IQR 2.0–6.7). 58%(32/55) had no CS and, as expected, their median age at surgery than those with CS (9.3 vs 2.4 years, p<0.01). The indication for surgery was Ux alone in 46%(25/55) and primarily neurologic (Nx) in 38%(21/55) with CS present in 24%(6/25) and 62%(13/21), respectively. 16%(9/55) had no clinical symptoms but an abnormal MRI ordered due to CS (dermal sinus in 55%, 5/9). Median age at surgery for the Ux, Nx and no-symptom groups were 9.29, 8.65 and 1.21 years, respectively (ANOVA p<0.0001). In the Ux group, mean age at surgery with and without CS was 9 and 7.7 years (p=0.5). Fatty filum was the most common MRI diagnosis both overall (32/55, 58%), and in Ux patients (12/25, 64%). Early and late urologic outcomes for any symptomatic patient in Ux and Nx groups are shown in Table 1. Only subjective urinary symptoms showed a significant improvement. 21 patients with pre and postoperative ultrasounds had no clear improvement in hydronephrosis at last follow up. In the 13 patients with pre and postoperative UDS, detrusor overactivity was the only parameter that significantly improved at median follow up of 15.4 months (10 vs 3 patients, p<0.01). CONCLUSIONS Though Ux may be a common indication for neurosurgical intervention, in our series only subjective urinary symptoms and detrusor overactivity improved after surgery. These findings may help families establish realistic expectations about potential benefits of cord detethering for urologic findings in children with OSD. Table 1.
