Evaluating the utility of routine urine culture and antibiotic treatment in children with neurogenic bladder undergoing intradetrusor OnabotulinumtoxinA injection.

Introduction: OnabotulinumtoxinA is used as treatment for refractory idiopathic and neurogenic detrusor overactivity in children. Many patients perform intermittent self-catheterization and therefore have higher rates of asymptomatic bacteriuria, which may increase their risk of symptomatic urinary tract infection (UTI) following treatment. Multiple injections are often needed due to the short-term efficacy of onabotulinumtoxinA treatment, which may also increase the risk of UTI.

Testicular Core Extraction: Important Technique for Determining Sperm Retrieval Method in Non-obstructive Azoospermia.

Objective: To assess the value of preliminary testicular core extraction (TCE) as a tool for determining whether to pursue clinic testicular extraction (cTESE) versus microscopic testicular sperm extraction (mTESE) to minimize both financial burden and procedural complexity.

Methods: All men with non-obstructive azoospermia (NOA) from 2018 to 2022 who underwent clinic TCE were analyzed. Patients who were found to have sperm on initial TCE were recommended cTESE.
