A bladder diary is the first step toward accurate diagnosis. Objective data instead of subjective complaints.
Keeping a diary for 2–3 days gives your doctor an objective picture of bladder function. This avoids unnecessary investigations, leads to an accurate diagnosis, and helps choose the right treatment.
Overactive Bladder
OAB
Sudden, strong urges to urinate that are difficult to control. Frequent toilet visits — more than 8 times a day, including at night (nocturia). Sometimes accompanied by involuntary urine leaks.
How the diary helps
Records frequency, urgency intensity, and leakage episodes over 2–3 days. The urologist sees the real pattern — how often, at what time, what volume — and precisely tailors therapy: behavioural, pharmacological, or physiotherapy.
Urinary Incontinence
Incontinence
Stress incontinence — leaking during coughing, sneezing, laughter, or exercise. Urgency incontinence — an overwhelming urge with immediate leakage. Mixed — a combination of both. Nocturnal enuresis. Each type requires a fundamentally different treatment approach.
How the diary helps
Records the time, circumstances, and approximate volume of each episode. This enables the doctor to distinguish the type of incontinence precisely and prescribe the right treatment: Kegel exercises, medication, electrical stimulation, or surgery.
Cystitis, Urethritis, and Urinary Tract Infections
Cystitis / UTI
Burning and pain during urination, frequent urges with small urine volumes, feeling of incomplete emptying. Lower abdominal pain, sometimes blood in urine. Includes acute cystitis, urethritis, recurrent UTIs, and interstitial cystitis.
How the diary helps
Documents symptoms over time: frequency, volume, pain intensity day by day. The doctor sees the response to antibiotics in real numbers, assesses treatment efficacy objectively, and decides whether to change the regimen without extra visits.
Nocturia (Night-time Urination)
Nocturia
Waking at night to urinate — more than twice per night. Significantly disrupts sleep and reduces quality of life. May be a symptom of OAB, BPH, chronic heart failure, or simply a habit of drinking a lot of fluid in the evening.
How the diary helps
Shows how many times the patient wakes at night and what volume is passed each episode. Data helps distinguish the causes of nocturia — bladder, systemic, or behavioural — and choose appropriate treatment.
Voiding Difficulty and BPH
BPH / Voiding
Weak or intermittent stream, straining, feeling of incomplete emptying. Characteristic of benign prostatic hyperplasia (BPH), urethral stricture, or neurogenic bladder. In men often combined with nocturia.
How the diary helps
Paired with the FlowSelfie device, provides a quantitative picture: flow speed and volume for each urination. One visit is sufficient for preliminary obstruction assessment. Data trends show BPH treatment efficacy.
Post-operative Monitoring
Post-op
After surgery on the bladder, prostate, or pelvic organs, it is important to objectively track recovery. Urination frequency and volume, irritative or obstructive symptoms — markers of rehabilitation progress.
How the diary helps
The surgeon sees recovery progress in numbers without extra clinic visits. The patient generates a PDF report and sends it before the follow-up appointment — data for the entire period between visits.
Kidney Stones (Urolithiasis)
Urolithiasis
Periodic pain in the lower back and along the ureter, blood in urine, frequent painful urges when stones are present. A key preventive measure for urolithiasis is maintaining daily urine output above 2 litres.
How the diary helps
Shows the actual daily urine volume and flags when it drops — an early marker of recurrent stone formation risk. Convenient to monitor fluid intake in concrete numbers and adjust behaviour.
Fluid Balance Monitoring
Fluid Balance
For athletes, people with chronic heart failure, those taking diuretics, or patients with kidney disease — comparing fluid intake with urine output is critically important. An imbalance may signal a serious condition.
How the diary helps
Clear intake vs. output balance per day without tables or manual calculations. A trend chart helps the doctor assess progress and promptly adjust diuretic therapy or fluid regimen.
Conditions where a diary is particularly important
A bladder diary is a diagnostic and monitoring tool across a broad range of urological and systemic conditions.
Overactive Bladder (OAB) Assess frequency and urgency intensity, and the efficacy of behavioural and pharmacological therapy
Urinary incontinence (stress, urgency, mixed) Record leakage circumstances and volume to choose the optimal treatment approach
