Dr. Di Wu is a founding member of Integrated Pelvic Care (IPC), a clinical and educational network advancing pelvic health for men, women, and the clinicians who treat them. With cross-training in both medicine and physical therapy, he holds a perspective on how pelvic dysfunction shows up at the intersection of two disciplines that rarely speak to each other in clinical practice — a gap that explains why so many patients cycle between urologists, primary care, and physiotherapists without arriving at a coherent plan. His central contribution to the field is the IPC 4Is functional diagnosis framework — Inflammation, Incoordination, Irritation, Incontinence — which clinicians use to interpret 3-day bladder diaries and sequence pelvic-floor treatment in a way that addresses root causes rather than chasing surface symptoms. The 4Is framework guides practice across the IPC network's clinics and informs the calculations behind every metric in this app's clinical export. When a clinician opens the PDF from a My Flow Check diary, they're reading the same numbers, in the same order, that the IPC methodology asks for at the first visit. Dr. Wu's writing for My Flow Check focuses on translating clinical IPC methodology into plain-language education for the people who actually live with these conditions. His view: a patient who understands the pattern in their own data has already done half the work of treatment. The 3-day diary is the entry point — the rest is a partnership between the patient, the clinician, and the data they look at together.

Feeling that your bladder isn't empty after peeing is often a signal problem, not a plumbing problem. The diary plus a scan sorts which version you have.
Pee Dripping After Urination: Real Fixes
Pee dripping after urination is post-void dribble. In men it is urine left in the urethra; in women, urine pooled in the vagina. Both have quick fixes.
Underactive Bladder: The Muscle That Lost Its Squeeze
An underactive bladder is a tired bladder muscle that cannot empty fully. Track three days in a diary to see the pattern and skip the wrong meds.
A Weak Urine Stream Is a Clue, Not a Diagnosis
A weak urine stream is a clue, not a diagnosis. The cause may be plumbing, the bladder muscle, or pelvic-floor coordination. A 3-day diary tells which.
Nocturia
Nocturia means waking from sleep to urinate. One trip can be normal; two or more nightly often signals an underlying pattern worth understanding.
Overactive bladder (OAB)
Overactive bladder is a pattern of urgency, often with daytime frequency and nighttime waking. Here is what it means and what tends to help.
Post-void residual (PVR)
Post-void residual is the urine left in the bladder right after you finish urinating. Measured by ultrasound or catheter, it tells a clinician how completely the bladder empties.
Urinary frequency
Urinary frequency is going to the bathroom more often than typical, usually defined as 8 or more daytime voids. Here is what counts and what tends to drive it.
Urinary urgency
Urgency is a sudden, hard-to-defer need to urinate. It is the most diagnostic symptom of overactive bladder and the symptom most likely to interfere with daily life.
