Urinary Urgency: Phenotype Before You Prescribe
Urinary urgency masquerades as overactive bladder. Phenotype it on the bladder diary, excluding overflow and fluid imbalance, before reaching for a drug.
Uroflowmetry Interpretation in Context
Uroflowmetry interpretation for clinicians: read flow curve, Qmax, and voided volume against the bladder diary and PVR, because a low Qmax is ambiguous.
Bladder Outlet Obstruction ICD-10: N40.1 vs N32.0 vs N13.9
Bladder outlet obstruction ICD-10 coding: N40.1 for BPH, N32.0 for bladder-neck, N13.9 for unspecified, plus female BOO and post-prostatectomy stacks.
Detrusor Overactivity: Diary First, Then Urodynamics
Detrusor overactivity is a UDS finding, not OAB. The bladder diary triages most cases before urodynamics; subtype changes which prescription works.
ICD-10 Codes for Urinary Urgency: LUTS by 4Is Bucket
ICD-10 codes for urinary urgency: R39.15 for the symptom, N32.81 for OAB syndrome, N39.41 with leakage. The LUTS code menu organized by IPC 4Is buckets.
Underactive Bladder: A Diary-First Workup Before Urodynamics
Underactive bladder hides under BPH. The diary plus PVR is what tells you which bucket the patient sits in before urodynamics confirms it. Workup guide.
Post-Void Residual: The Voiding-Impairment Gate-Check
Post-void residual is the singular gate-check on the Voiding axis: cutoffs, measurement pitfalls, the kegel caution, and the practical urology algorithm.
ICIQ-OAB: Item-by-Item Interpretation for the 4Is Workup
The ICIQ-OAB scores OAB symptom severity 0 to 16. The four items map to four IPC 4Is workup paths. How to read it, score it, and pair it with the diary.
Differential Diagnosis of Polyuria: Diary-First Workup
Differential diagnosis of polyuria, anchored to the IPC 4Is framework: how a 3-day bladder diary triages four patterns before the endocrine workup runs.
Nocturnal Polyuria Index (NPi): Calculation and Workup
Calculating the nocturnal polyuria index from a bladder diary: age-stratified thresholds, the 4Is gateway, and the PT-led workup before any drug.
Frequency Volume Chart: The ICS-Formal Bladder Diary
A frequency volume chart is the ICS-formal name for the volumetric core of a bladder diary. The chart that produces 24hVV, MVV, AVV, and NPi at the desk.
Normal Capacity of the Bladder: Functional vs Anatomical
The 300-500 mL textbook range is anatomical capacity. The number that drives clinical decisions is functional capacity, read off a 3-day bladder diary.
The Continence Assessment Tool a Clinician Actually Needs
The continence assessment tool a clinician actually needs: five validated instruments, the 3-day bladder diary, and the 4Is functional diagnosis framework.

What is a bladder diary?
A bladder diary turns three days of voids, fluids, and leaks into the four numbers that drive a real LUTS diagnosis. The cheapest test in pelvic care.
