Correlation between motor function and lower urinary tract dysfunction in patients with infantile cerebral palsy

Area of Science:

• Urology
• Neurology
• Pediatrics

Background:

• Infantile cerebral palsy (CP) often presents with complex neurogenic bladder dysfunction.
• Understanding the relationship between motor impairment and urodynamic findings is crucial for patient management.

Purpose of the Study:

• To evaluate urodynamic findings in patients with infantile cerebral palsy (CP).
• To correlate these findings with the degree of motor function impairment using the Gross Motor Function Classification System for CP (GMFCS).

Main Methods:

• Videourodynamic investigation was performed on 29 patients (3-53 years) with CP.
• Patients were classified using the GMFCS, ranging from Level I (most independent) to Level V (least independent).
• Patients were divided into symptomatic (Group 1) and asymptomatic (Group 2) groups.

Main Results:

• Symptomatic patients (Group 1) frequently exhibited reduced bladder compliance (91%) and increased detrusor leak point pressure (DLPP) (70%).
• Detrusor and pelvic floor overactivity were observed in all symptomatic patients (100%) and 83% of asymptomatic patients.
• Symptomatic patients generally had higher GMFCS levels compared to asymptomatic patients, who were not classified in the highest impairment levels (IV or V).

Conclusions:

• Urinary symptoms and abnormal urodynamic findings correlate with the severity of motor function impairment in CP patients as defined by GMFCS.
• Pathological urodynamic findings are not exclusive to symptomatic individuals and can be present in asymptomatic CP patients.
