Prospective study of transcutaneous parasacral electrical stimulation for overactive bladder in children: long-term results.
OBJECTIVE
We evaluated the long-term success of transcutaneous parasacral electrical stimulation for overactive bladder in children.


METHODS
We prospectively evaluated children who underwent transcutaneous parasacral electrical stimulation for overactive bladder. All patients had symptoms of overactive bladder, bell curve in uroflowmetry and low post-void residual urine. The procedure was performed using a frequency of 10 Hz for 20-minute sessions 3 times weekly for a maximum of 20 sessions. Initial and long-term (more than 6 months) success rates were evaluated.


RESULTS
Transcutaneous parasacral electrical stimulation was performed in 36 girls and 13 boys with a mean age of 10.2 years (range 5 to 17). Mean followup was 35.3 months (range 6 to 80). Before treatment urgency, daytime incontinence and urinary tract infection were seen in 100%, 88% and 71% of cases, respectively. Initial success (full response) was demonstrated in 79% of patients for urgency, 76% for incontinence and 77% for all symptoms. Continued success was seen in 84% of patients for urgency, 74% for daytime incontinence and 78% for all symptoms. If the 30 patients with at least 2 years of followup were considered, treatment was successful in 73%. Recurrence of symptoms after a full response was seen in 10% of cases. Two of 33 patients (6%) with urinary tract infection before the procedure still had infection after treatment.


CONCLUSIONS
Transcutaneous parasacral electrical stimulation is well tolerated, and demonstrates short and long-term effectiveness in treating overactive bladder in children. Symptoms eventually will recur in 10% of patients.
