Dear Ms Weigle A few more questions before i can give you my opinion. I am a pediatric urologist and would like you to please answer these to the best of your ability i) does your boy have any wetting of his underclothes, wetting the bed, poor urinary stream ? ii) has he had urinary tract infections even after the pyeloplasty ? iii) has your boy had any difficulty passing stools / soiling his underpants ? iv) has his spine been evaluated for spina bifida or has he undergone any test like Urodynamics ? v) Has he had a Voiding cysto urethrogram - a test where dye is placed in the bladder and then he is asked to pass urine and xrays taken at this time If anyof the above tests are available, it would be useful to upload / mail these as well. Regards dr Antony Robert Charles Pediatric Surgeon and Pediatric Urologist
