Current Research:
  • Examining barriers and thresholds to referral for antenatal assessment by Pediatric Urology after detection of antenatal hydronephrosis (using BORN data).
  • Randomized controlled trial on biofeedback in children with dysfunctional elimination syndrome with recurrent UTIs and urinary incontinence.
  • Assessment of the usefulness of Urodynamics as an aid in the decision making process for neurosurgery in infants with cutaneous stigmata of tethered cord.
  • Study on urinary infection, bacterial prevalence and resistance profile in patients performing intermittent catheterization for neurogenic bladder.
  • Systematic review of the literature on bladder function of infants and non-toilet trained children.
  • Prospective double-blinded, age stratified randomized, controlled trial on the addition of clonidine to 0.2% ropivacaine for wound instillation after minor lower abdominal surgery in Children.
  • The impact of Trendelenburg position on respiratory system mechanics during laparoscopic surgery for intra-abdominal testes in children.
  • Voiding urosonography with ultrasound contrast agent, a radiation-free technique for monitoring of vesico-ureteral reflux in children.
