[THREE CASES OF FEMALE URINARY DYSFUNCTION DIAGNOSED BY URODYNAMIC STUDY AND VOIDING CYSTOURETHROGRAPHY ACCURATELY]

Area of Science:

• Urology
• Diagnostic Imaging
• Female Lower Urinary Tract Dysfunction

Background:

• Differentiating bladder outlet obstruction (BOO) from detrusor underactivity (DU) is crucial for managing female urinary dysfunction.
• Standard diagnostic tools may present challenges in distinguishing these conditions accurately.

Purpose of the Study:

• To evaluate the combined utility of urodynamic study (UDS) and voiding cystourethrography (VCUG) in differentiating BOO and DU in female patients.
• To present case studies illustrating the diagnostic capabilities of this combined approach.

Main Methods:

• Retrospective analysis of three female patients with urinary dysfunction.
• Performance of UDS to assess bladder contractility and flow rates.
• VCUG (or videourodynamics) to visualize bladder neck opening, urethral function, and identify potential obstructions or reflux.

Main Results:

• Case 1: Diagnosed BOO due to bladder neck dysfunction (UDS: PdetQmax 86.6 cmH2O, Qmax 2.2 ml/s; VCUG: poor bladder neck opening, VUR).
• Case 2: Diagnosed BOO due to abnormal urethral function (UDS: PdetQmax 27.7 cmH2O, Qmax 5.3 ml/s; VCUG: open bladder neck, urethral narrowing).
• Case 3: Diagnosed DU (UDS: PdetQmax 18.3 cmH2O, Qmax 3.8 ml/s; VCUG: urethral dilatation).

Conclusions:

• The combination of UDS and VCUG is a valuable tool for the differential diagnosis of DU and BOO in women.
• This integrated diagnostic strategy aids in accurate etiological classification of urinary dysfunction.
• Improved diagnostic accuracy can lead to more targeted and effective treatment strategies for female lower urinary tract symptoms.
