Assessment overview
How this assessment usually works
Urinary and reproductive impairment uses AMA5 Chapter 7 with NSW replacement tables. The assessment must distinguish objective urinary dysfunction, reproductive pathology and neurological consequences instead of treating reported symptoms as one generic percentage.
For urinary and reproductive system, the assessor gives a medical opinion about permanent impairment under the NSW workers compensation guidelines; the assessor does not decide legal liability. Once the body-system method and percentage are understood, separate advice may be needed about Section 66 compensation, weekly payments, medical-expense time limits or work injury damages.
Injuries and diagnoses assessed in this body system
The referral and report should identify the accepted diagnosis precisely. Similar symptoms can use different assessment methods depending on the injured structure.
- loss or permanent disease of a kidney or ureter, renal transplantation and urinary diversion
- primary bladder disease, urethral disease and stress, urge, mixed or total urinary incontinence
- accepted male or female reproductive-system injury or disease
- sexual dysfunction supported by identifiable pathology
- neurogenic bladder, bowel or sexual dysfunction supported by spinal cord, cauda equina or bilateral nerve-root findings
When a permanent impairment assessment can occur
For urinary and reproductive system, assessment should occur only after maximum medical improvement (MMI). NSW Guidelines paragraph 1.15 describes a condition that is well stabilised and unlikely to change substantially during the next year, with or without treatment.
For urinary and reproductive system, if adequate treatment or rehabilitation could materially change the impairment, paragraph 1.16 says the assessment should be deferred. The report should explain why the timing is appropriate.
For urinary and reproductive system, recent diversion, reconstruction, medication change, infection, continence treatment or anticipated surgery may mean urinary or reproductive function is not yet stable enough for final assessment.
The NSW and AMA5 assessment method
The NSW Workers Compensation Guidelines prevail over AMA5 wherever the two differ. The method is a medical assessment framework, not a self-scoring exercise.
NSW Guidelines Chapter 7 applies AMA5 Chapter 7 with NSW replacement Tables 7.1-7.5 and specific incontinence and sexual-function modifications.
Primary kidney, ureter, bladder or urethral impairment uses the urinary chapter. Neurogenic bladder or sexual dysfunction from spinal or neurological injury may instead use the relevant nervous-system or spine table so that the same loss is not counted twice.
Sexual dysfunction requires identifiable pathology before a percentage can be assigned. Where a spinal cause is alleged, NSW paragraph 7.12 requires other objective evidence of spinal cord, cauda equina or bilateral nerve-root dysfunction.
The assessor should identify the exact urinary structure, objective test and replacement table rather than treating urgency, leakage or sexual symptoms as one generic impairment.
What the assessor actually measures
For urinary and reproductive system, the percentage should be traceable to relevant, stable and reproducible findings.
- renal anatomy and function, loss of an organ, transplant status and treatment dependence
- diversion type, appliance or catheter needs and stable postoperative function
- urinary frequency, nocturia, urge, stress leakage, pad use and clinically demonstrated continence loss
- urodynamic evidence of bladder reflex activity, voluntary control, residual urine and primary versus neurogenic cause
- urethral dysfunction, treatment response and frequency of leakage
- identified reproductive pathology, treatment and the age adjustment required by the applicable method
How the measurements are converted to WPI
NSW Table 7.1 gives diversion values: ureterointestinal diversion 10%, cutaneous ureterostomy 10%, nephrostomy 15%, neobladder or replacement cystoplasty 15%, and continent urinary diversion 20% WPI.
NSW Table 7.2 bladder classes are 0-15%, 16-40% and 41-70% WPI. Intermittent treatment with normal function between episodes is distinguished from continuous-treatment frequency or urge incontinence, and from loss of voluntary control or total incontinence.
NSW Table 7.3 urethral classes are 0-10%, 11-20% and 21-40% WPI, depending on treatment and the frequency or control of stress incontinence or dribbling.
For multiple incontinence patterns, paragraph 7.8 requires the highest-scoring supported condition to be used. Stress, urge and mixed values are not added together.
Separate permitted organ or neurological impairments are combined only after choosing the correct primary method and checking for overlap.
Verified category and table examples
These short examples show how the published method works. They do not predict an individual assessment.
| Finding or category | Published value or method | Source |
|---|---|---|
| Ureterointestinal diversion or cutaneous ureterostomy | 10% WPI | NSW Guidelines Table 7.1 |
| Nephrostomy or neobladder/replacement cystoplasty | 15% WPI | NSW Guidelines Table 7.1 |
| Continent urinary diversion | 20% WPI | NSW Guidelines Table 7.1 |
| Clinically demonstrable stress urinary incontinence | 11-25% WPI according to severity | NSW Guidelines paragraph 7.8 |
| Urge, mixed or nocturnal-enuresis category | 16-40% WPI according to severity | NSW Guidelines paragraph 7.8 |
| No sexual function possible, male reproductive method | Class 3 fixed at 20% WPI before any applicable age loading | NSW Guidelines paragraph 7.9 |
Worked illustrations
How the assessment method can operate
These paraphrased illustrations explain the published method. They are not estimates of another worker's WPI.
Illustration: use the supported incontinence method, not a sum
Assumed findings: After a stable accepted pelvic injury, a worker has clinically demonstrated mixed stress and urge incontinence requiring protective pads. Urodynamic and treating evidence supports the mixed pattern.
Method and arithmetic: NSW paragraph 7.8 places mixed incontinence within 16-40% WPI according to severity and requires the highest-scoring supported condition to be used. Separate stress and urge figures are not added.
What the illustration shows: The exact point depends on the objective findings, frequency, control and treatment evidence. This paraphrased illustration is not an estimate.
Method source: NSW Guidelines paragraphs 7.5-7.8 and Tables 7.2-7.3
Illustration: a neurogenic bladder uses the neurological pathway
Assumed findings: A worker with an accepted spinal cord injury develops stable bladder dysfunction supported by urodynamics and objective cord findings.
Method and arithmetic: The assessor checks the spinal or neurological bladder method rather than automatically applying the primary bladder-disease table, then avoids counting the same bladder loss under both chapters.
What the illustration shows: The controlling method follows the cause of the dysfunction. This is an illustration only.
Method source: NSW Guidelines paragraph 7.12; AMA5 Tables 13-9, 13-21 or 15-6 as applicable
What does not establish WPI by itself
These matters can remain medically and practically important, but they do not replace the measurements or category requirements in the applicable method.
- reported urgency, leakage or sexual dysfunction without identifiable pathology and the objective evidence required by the selected table
- combining separate stress, urge and mixed incontinence values
- pad use alone without clinical explanation of cause, frequency and control
- attributing bladder or sexual dysfunction to spinal injury without objective neurological signs
- using a primary bladder table and a neurological bladder table for the same loss
Evidence checklist
The assessor should receive enough material to test the accepted injury, stability, measurable impairment and any deduction.
- the accepted injury or disease description and any insurer liability decisions
- contemporaneous GP, hospital and treating-specialist records
- relevant investigations, pathology, procedure reports and treatment history
- earlier impairment assessments and evidence about any pre-existing impairment
- a current clinical opinion explaining stability and whether material improvement remains likely
- urology, nephrology, gynaecology or reproductive-specialist reports as applicable
- renal-function, imaging, urodynamic and other objective urinary testing
- records of pads, appliances, catheters, diversion, transplantation, medication and treatment response
- operation and reconstruction reports and stable continence or sexual-function history
- objective neurological evidence where a spinal or nervous-system cause is alleged
Common insurer or report disputes
A disagreement about urinary and reproductive system WPI may concern the accepted diagnosis, the body-system findings, the selected method, a deduction or the way another impairment was handled. The report should identify the disputed step rather than leave the percentage unexplained.
- symptoms are rated without identifiable pathology
- stress and urge incontinence percentages are added together
- severity within a broad range is unexplained
- spinal sexual dysfunction is alleged without objective neurological evidence

Questions to ask when the report comes back
These questions help identify whether the report explains its method and evidence. They do not replace medical or legal advice about the particular assessment.
- Which NSW replacement table or AMA5 method was used?
- What objective findings support severity?
- Were incontinence categories kept non-combinable?
- Is any spinal attribution objectively supported?
How this connects to thresholds and strategy
In an urinary and reproductive system claim, SIRA's permanent impairment thresholds must be applied to the accepted injury and the supported body-system percentage. The general thresholds are 11% or more permanent impairment for physical injury and 15% or more for primary psychological injury; secondary psychological injury is treated differently. A threshold is an eligibility checkpoint, not a promised payment.
A low urinary and reproductive system WPI opinion may affect weekly-payment planning, treatment time-limit issues, dispute posture and whether work injury damages threshold advice is required. Before the opinion is relied on, check the relevant measurements, body-system method, deduction and practical consequences.
Questions workers often ask
Can stress and urge incontinence values be combined?
No. NSW paragraph 7.8 requires the highest-scoring supported incontinence condition to be used.
Does sexual dysfunction automatically establish WPI?
No. NSW paragraph 7.2 requires identifiable pathology before an impairment percentage can be assigned.
What supports sexual dysfunction from a spinal injury?
NSW paragraph 7.12 requires other objective evidence of spinal cord, cauda equina or bilateral nerve-root dysfunction.
When can this system be assessed?
After maximum medical improvement, with stable objective findings and the records needed by the selected urinary or reproductive method.
