The Role of Urodynamic Studies in Female Patients with Non-Neurogenic Lower Urinary Tract Dysfunction: A Retrospective Analysis.

OBJECTIVE

To evaluate the diagnostic role of urodynamic studies (UDS) in female lower urinary tract dysfunction (LUTD) and its correlation with clinical symptoms.

METHODS

A retrospective study design was followed, and 89 female patients were included (2020-2025). SPSS was used for descriptive and multivariate analyses of the association between obstetric history and pelvic surgeries with UDS findings.

RESULTS

Forty-three (48.3%), 18 (20.2%), and 8 (9%) had no comorbidities, hypertension (HTN), and diabetes mellitus, respectively. Sixteen (18%) had urological problems, 54 (60.7%) were grand multiparous, and 20 (22.5%) had cesarean section (C-section). The mean volumes at first sensation, first desire to void, and strong desire to void were 111.83 ± 48.43 mL, 184.36 ± 70.73 mL, and 289.24 ± 93.60 mL, respectively. Urodynamic study findings for the mean maximum cystometric capacity were 370.46 ± 102.20 mL, maximum flow rate of 41.42 ± 47.04 mL/sec, post-void residual volume of 137.25 ± 144.0 mL, voided volume of 378.86 ± 164.87 mL, Valsalva leak point pressure of 7.43 ± 44.73 cm/H2O, and detrusor pressure at capacity was 10.86 ± 18.97 cm/H2O. Most patients had normal bladder compliance; 2 (2.2%) reported reduced compliance. Urethral assessment indicated that only 4 (4.5%) had obstructive urethra, stress incontinence, and 4 (4.5%) correlated with UDS and clinical symptoms (P < .05). A non-significant association was found between storage, voiding symptoms with UDS outcomes, except for hesitancy (P = .01) and straining (P = .04). Multinomial logistic regression analysis indicated no significant correlation of obstetric history and pelvic surgeries with UDS.

CONCLUSION

Urodynamic studies may be helpful in providing objective functional assessment in selected or complex cases. However, in the population, UDS did not consistently confirm these cases.
