1 Initial presentation
Patient: Marta, 62 years old.
Chief complaint: involuntary urine leakage for about a year.
The patient reports:
She has no fever, hematuria, or flank pain.
Question 1 · What information is most important to obtain now?
Show answer and explanation ▾
Correct answer: B
Urinary incontinence is a symptom. The first goal is to characterize it. We should ask when she leaks urine, whether it is related to urgency, coughing, or exertion, voiding frequency, nocturia, and other urinary symptoms.
2 Second stage · History
On further questioning, Marta reports:
- she urinates approximately every 1–2 hours;
- she has urgency several times a day;
- she has 3–4 weekly leakage episodes associated with urgency;
- she gets up twice a night to urinate;
- she occasionally leaks a few drops when she sneezes, but this symptom does not bother her;
- she has no difficulty starting urination;
- she feels she empties her bladder completely;
- she has no recurrent urinary tract infections;
- she has had three vaginal deliveries;
- she has no history of neurological disease.
Question 2 · What is the predominant symptom?
Show answer and explanation ▾
Correct answer: B
Urgency is the cardinal symptom of overactive bladder. It may be accompanied by increased frequency, nocturia, and urgency urinary incontinence.
3 Third stage · Diagnosis
Question 3 · What is the most likely clinical diagnosis?
Show answer and explanation ▾
Correct answer: B
The patient has urgency as the predominant symptom, accompanied by frequency, nocturia and urgency-associated leakage.
Although she reports an occasional leak when sneezing, the predominant component is clearly urgency.
Key concept
Overactive bladder is a clinical syndrome. It is not synonymous with detrusor overactivity, which is a urodynamic finding.
4 Fourth stage · Workup
The physical exam shows no relevant findings.
The following are ordered:
- urinalysis: normal;
- post-void residual: 35 mL.
Question 4 · What simple tool could provide additional information?
Show answer and explanation ▾
Correct answer: B
A bladder diary makes it possible to record, over several days:
- voiding times;
- volumes;
- fluid intake;
- episodes of urgency;
- leakage;
- nocturia.
5 Fifth stage · Urodynamics
Question 5 · Is urodynamics mandatory before starting treatment?
Show answer and explanation ▾
Correct answer: C
The initial evaluation makes it possible to guide most patients without the need for invasive tests.
Urodynamics is reserved for situations in which knowing the functional mechanism could change a diagnostic or therapeutic decision.
What does urodynamics study?
It allows a functional analysis of how the bladder and urethra behave during the storage and voiding phases.
Pearl for the student
Overactive bladder = clinical diagnosis.
Detrusor overactivity = urodynamic finding.
6 Sixth stage · Treatment
Question 6 · What would be a reasonable initial approach?
Show answer and explanation ▾
Correct answer: B
Initially, the following can be prescribed:
- education about the problem;
- adjustment of fluid intake;
- reduction of bladder irritants when appropriate;
- bladder training;
- bladder diary;
- pelvic floor rehabilitation in selected patients.
If symptoms persist, pharmacologic treatments can be considered.
In refractory patients there are alternatives such as intravesical botulinum toxin and neuromodulation.
7 Case twist
Six months later, Marta returns for a visit. She now says:
Question 7 · What changed?
Show answer and explanation ▾
Correct answer: B
The patient probably had urgency and stress components from the start. As the urgency component improves, stress incontinence becomes the predominant symptom.
This introduces the student to an important concept: symptoms can coexist, and treatment should be directed mainly at the component that most affects the patient's quality of life.
What should the student learn from this case?
By the end, the student should be able to differentiate:
- Leakage when coughing or exercising → stress incontinence.
- Sudden desire that is hard to postpone → urgency.
- Urgency + frequency ± nocturia ± urgency incontinence → overactive bladder syndrome.
- Combination of stress and urgency → mixed incontinence.
- Storage/voiding problems associated with neurological disease → consider neurogenic lower urinary tract dysfunction.
First characterize the symptom → then identify the likely mechanism → finally select tests and treatment.
