Indications, findings, and clinical impact of invasive pediatric urodynamic studies in Iraqi children.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Pediatric urodynamic study (UDS) provides an objective functional assessment of lower urinary tract dysfunction and assists in identifying high-risk bladder abnormalities associated with renal deterioration in children. However, regional evidence regarding pediatric UDS findings and their clinical implications remains limited in the Kurdistan Region of Iraq. Objective: To evaluate the clinical indications, urodynamic findings, and impact of pediatric UDS on patient management among children undergoing evaluation at a tertiary pediatric referral centre in Erbil, Iraq. Methods: This retrospective observational study included pediatric patients who underwent invasive UDS between January 2019 and December 2025 at a tertiary pediatric hospital in the Kurdistan Region of Iraq. Demographic characteristics, clinical indications, urodynamic findings, and treatment modifications following UDS were retrospectively collected from archived medical records and urodynamic reports. Associations between selected urodynamic abnormalities and treatment adjustment were evaluated using Fisher's exact test. Results: A total of 47 children were included, with a median age of 3.0 years (IQR, 7.0), and 78.7% were male. Vesicoureteral reflux (25.5%), posterior urethral valve (19.1%), and functional urinary incontinence (14.9%) were the most common indications for UDS. Abnormal urodynamic findings were identified in 59.6% of patients, with detrusor overactivity (21.3%), obstructive voiding (19.1%), underactive bladder (17.0%), reduced bladder compliance (19.1%), elevated detrusor leak point pressure (DLPP >40 cmH₂O; 12.8%), and abnormal sphincteric activity (10.6%) being the most frequent abnormalities. Treatment modification following UDS occurred in 48.9% of patients. Reduced bladder compliance was significantly associated with treatment adjustment ( Conclusion: Pediatric UDS provided clinically valuable functional information and influenced individualized management decisions in children with complex lower urinary tract disorders in the Kurdistan Region of Iraq. Reduced bladder compliance was associated with treatment modification following UDS, highlighting its clinical importance in guiding therapeutic decision-making. These findings provide one of the first regional datasets describing the indications, urodynamic findings, and management implications of pediatric UDS in Iraq.
