Hello!
With this kidney infection was your son evaluated by a urologist?
Typically in boys, urinary tract and kidney infections are much less common than females and the first infection warrants them a further evaluation to look for the cause. Boys have a much longer urethra than females and if he is getting infections, it is important to make sure there is not anything anatomical going on. With his current symptoms, I would recommend that he have a urinalysis for further evaluation. The lower stomach could be the bladder area which can be irritated with urologic infections. Regardless I recommend that the patient be evaluated in person by a medical professional for a urinalysis and exam. If it is another infection and he has not been evaluated by urology then that also needs to take place.

Hi and thanks for the question,
Its possible that it could be another kidney infection. Recognition of the fact that he does not pee as frequent as he used to is wort investigation. Cloudy urine associated with lower abdominal pain could be suggestive of a urinary tract infection like an infection of the bladder (Cystitis). Recurrent kidney infections in male children especially deserve more keener looks due to an increased rate of posterior urethral valves, a malformation that predisposes them to to infections.
Left untreated increases the risk of these children developing chronic kidney failure. A urine analysis and culture, urinalysis for urine protein and kidney function tests are important baseline examinations. A confirmed in urinary tract infection or altered kidney function test results could mandate more invasive urologic investigations. Consulting a pediatrician or pediatric urologist for a proper evaluation could be of great utility.
Thanks and best regards,

Hi,
Thank you for your query,
Your child seems to have another urinary tract infection.
In children with underlying kidney anomalies like vesico ureteral reflex, abnormal ureteral insertions, there are chances of getting repeated urine infections.
Urine to be given for routine examination and culture and sensitivity to know the causative bacteria.
Further evaluation is required with Ultrasound abdomen and MCUG (micturating cystourethrogram) to know the underlying anomalies.
Long term antibiotic prophylaxis with antibiotics and correction of underlying structural abnormality is important to prevent further infections.
Hope I have answered your query.
