Match each patient's clinical presentation with its most likely underlying pathophysiological mechanism.
- A 50-year-old woman with a history of three vaginal deliveries reports involuntary urine leakage that occurs exclusively when she laughs or sneezes.Loss of pelvic floor support causing urethral hypermobility
- A 65-year-old woman describes a sudden, overwhelming need to void that frequently results in urinary leakage before she can reach the toilet.Uninhibited detrusor muscle contractions during bladder filling
- A 72-year-old woman with advanced diabetic neuropathy experiences constant urinary dribbling and a consistently elevated post-void residual volume.Impaired detrusor contractility leading to bladder overdistension
- A 38-year-old woman develops continuous pooling of clear fluid in the vaginal vault 10 days after undergoing a radical hysterectomy for cervical cancer.Iatrogenic tract formation between the bladder and vaginal apex
Cevap
The presentations match as follows: stress incontinence with urethral hypermobility, urgency incontinence with detrusor overactivity, overflow incontinence with impaired detrusor contractility, and continuous leakage after surgery with an iatrogenic tract.
Each patient's clinical presentation directly maps to the classic pathophysiological mechanism of the respective urogynecologic condition: stress incontinence (urethral hypermobility), urgency incontinence (detrusor overactivity), overflow incontinence (impaired contractility), and vesicovaginal fistula (iatrogenic tract).
