title: Bladder dysfunction after bilateral ectopic ureterocele repair.
abstract: OBJECTIVE
  We examined postoperative outcome, with emphasis on bladder function, in pediatric patients who underwent bilateral ectopic ureterocele repair.
  
  
  METHODS
  We reviewed the records of 117 patients with orthotopic and ectopic ureteroceles treated between 1977 and 2000. Twelve of these patients had bilateral ectopic ureteroceles. All patients with bilateral ureteroceles were females 1 day to 2 years old at referral. Initial treatment was transureteral puncture in 6 cases, transurethral unroofing in 2 and extravesical bilateral reimplantation in 1. Of the remaining 3 patients the initial treatment was unilateral heminephroureterectomy in 1 and bilateral heminephroureterectomy in 2. Definitive treatment included bilateral upper to lower ureteroureterostomy, ureterocelectomy with trigonal and bladder neck reconstruction, and bilateral ureteroneocystotomy with or without tapering of the recipient ureter. In patients who underwent upper pole partial nephrectomy the distal upper pole ureter was removed in conjunction with trigonal surgery and ureteroneocystotomy.
  
  
  RESULTS
  There was significant morbidity in this group of patients, including voiding dysfunction and poor bladder emptying with residual urine greater than 20% of bladder capacity in 7 of 10 patients studied by serial bladder ultrasonography. Urodynamic evaluation in 3 patients revealed increased bladder compliance and large volume residual urine. Of these 3 patients 2 perform clean intermittent catheterization. Recurrent symptomatic bacteruria was noted in 7 of the 12 patients.
  
  
  CONCLUSIONS
  Patients undergoing bilateral ectopic ureterocele repair are at increased risk for postoperative voiding dysfunction. Whether this risk is present preoperatively or is a result of trigonal surgery is unclear.
