Hinman syndrome

What it is

From: Orphanet

Hinman syndrome (HS) or non-neurogenic neurogenic bladder is a voiding dysfunction of the bladder of neuropsychological origin that is characterized by functional bladder outlet obstruction in the absence of neurologic deficits.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Bladder trabeculation · Frequent (79-30%)

Muscular projections that protrude into the lumen of the bladder, criss-crossing the walls of the bladder on its inner surface.

Enuresis · Frequent (79-30%)

Lack of the ability to control the urinary bladder leading to involuntary urination at an age where control of the bladder should already be possible.

Recurrent urinary tract infections · Frequent (79-30%)

Repeated infections of the urinary tract.

Urinary bladder wall hypertrophy · Frequent (79-30%)

Increase in thickness of the wall of the urinary bladder. This finding may be seen in conditions such as bladder outlet obstruction and may be accompanied by increased trabeculation of the bladder wall musculature.

Urinary incontinence · Frequent (79-30%)

Loss of the ability to control the urinary bladder leading to involuntary urination.

Urinary retention · Frequent (79-30%)

Inability to completely empty the urinary bladder during the process of urination.

Urinary urgency · Frequent (79-30%)

Urge incontinence is the strong, sudden need to urinate.

Vesicoureteral reflux · Frequent (79-30%)

Abnormal (retrograde) movement of urine from the bladder into ureters or kidneys related to inadequacy of the valvular mechanism at the ureterovesicular junction or other causes.

Encopresis · Frequent (79-30%)

Abdominal pain · Occasional (29-5%)

An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) and perceived to originate in the abdomen.

Constipation · Occasional (29-5%)

Infrequent or difficult evacuation of feces.

Flank pain · Occasional (29-5%)

An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) and perceived to originate in the flank.

Hydronephrosis · Occasional (29-5%)

Severe distention of the kidney with dilation of the renal pelvis and calices.

Nausea · Occasional (29-5%)

A sensation of unease in the stomach together with an urge to vomit.

All ages

Which doctor should you see?

The suggested department for discussing Hinman syndrome is Urology, with a urologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which urinary or reproductive symptoms need further assessment?
• Could a blockage, structural problem or another cause be involved?
• What are the alternatives if a procedure is suggested?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Hinman syndrome. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
