Lack of morbidity from urodynamic studies in children with asymptomatic bacteriuria

Area of Science:

• Pediatric Urology
• Nephrology
• Infectious Diseases

Background:

• Asymptomatic bacteriuria is common in pediatric patients using clean intermittent catheterization (CIC).
• Prophylactic antibiotics are standard for surgical procedures but their role before diagnostic procedures is unclear.
• Investigating morbidity from urodynamic evaluation in patients with asymptomatic bacteriuria is crucial.

Purpose of the Study:

• To assess the safety and morbidity of urodynamic evaluation in pediatric patients with asymptomatic bacteriuria.
• To determine if asymptomatic bacteriuria impacts urodynamic findings or leads to symptomatic urinary tract infections (UTIs).

Main Methods:

• 69 pediatric patients (mean age 10 years) with neurogenic bladder, mostly on CIC, underwent urodynamic evaluation.
• Urine cultures were obtained during cystometrograms; 46 had bacteriuria, 23 had sterile urine.
• Patients were monitored for symptomatic UTIs within one week post-procedure.

Main Results:

• No symptomatic UTIs occurred in any patient post-urodynamic studies.
• Urodynamic findings (capacity, compliance) showed no significant difference between patients with and without bacteriuria (P=0.4).
• Overall, 65% of patients with bacteriuria and 52% without had adequate bladder capacity and compliance.

Conclusions:

• Urodynamic studies are safe in pediatric patients with asymptomatic bacteriuria.
• Routine urine cultures and prophylactic antibiotics are not necessary before urodynamic studies in this population.
• Findings support a less invasive approach for pediatric neurogenic bladder patients undergoing urodynamic evaluation.
