Genitourinary Secondary Conditions
Introduction to Genitourinary Secondary Connections
Genitourinary conditions frequently develop as secondary effects of service-connected disabilities. The genitourinary system’s complex interplay with vascular, neurological, and endocrine systems makes it particularly vulnerable to cascading effects from various primary conditions, whether through direct physiological impact, medication side effects, or neurological mechanisms.
Key Concepts
Genitourinary secondary conditions typically develop through these pathways:
- Medication effects on kidney function, urinary tract, or reproductive organs
- Vascular changes affecting genitourinary perfusion
- Neurological effects on bladder, sphincter, or sexual function
- Endocrine disruption affecting reproductive function
- Mechanical effects from musculoskeletal conditions
This chapter explores the most common genitourinary conditions that develop secondary to service-connected disabilities and provides the medical evidence and documentation strategies needed to successfully claim these conditions.
Kidney Conditions Secondary to Diabetes, Hypertension, or Medication Effects
Kidney conditions—including chronic kidney disease, diabetic nephropathy, and medication-induced nephropathy—frequently develop as secondary conditions to service-connected diabetes, hypertension, and medication side effects.
Medical Connection
The development of kidney conditions as secondary effects occurs through several established mechanisms:
Secondary to Diabetes Mellitus
Diabetes affects kidney function through:
- Glomerular hyperfiltration: Early increased filtration damages kidneys
- Glycosylation of proteins: Damages kidney structures
- Microvascular damage: Affects small vessels in kidneys
- Increased susceptibility to infection: Leading to pyelonephritis
- Papillary necrosis: Death of renal papillae
- Increased risk of kidney stones: From metabolic changes
Secondary to Hypertension
Hypertension affects kidney function through:
- Increased intraglomerular pressure: Damages filtering units
- Arteriosclerosis of renal vessels: Narrows blood supply
- Glomerulosclerosis: Scarring of glomeruli
- Tubular ischemia: Reduced blood flow to tubules
- Proteinuria: Protein leakage damages tubules
- Activation of inflammatory pathways: Promotes fibrosis
Secondary to Medication Effects
Various medications can affect kidney function:
- NSAIDs: Reduce renal blood flow, cause interstitial nephritis
- Certain antibiotics: Direct tubular toxicity
- Contrast agents: Cause contrast-induced nephropathy
- Proton pump inhibitors: Associated with interstitial nephritis
- Lithium: Causes nephrogenic diabetes insipidus, chronic tubulointerstitial nephropathy
- Chemotherapy agents: Many have nephrotoxic effects
Case Study: Diabetic Nephropathy Secondary to Diabetes
A veteran with service-connected diabetes mellitus (40% rating) developed progressive kidney dysfunction. His successful secondary claim included:
- Nephrology evaluation diagnosing diabetic nephropathy
- Laboratory evidence:
- Elevated creatinine (1.8 mg/dL)
- Reduced eGFR (42 mL/min/1.73m²)
- Persistent microalbuminuria
- Renal ultrasound showing changes consistent with diabetic nephropathy
- Nephrologist’s opinion stating that “the veteran’s chronic kidney disease is directly caused by his service-connected diabetes mellitus, as evidenced by the classic presentation, absence of other risk factors, and well-established causal relationship between diabetes and nephropathy”
- Documentation of progression from normal kidney function to Stage 3b CKD over 8 years of diabetes
- Evidence of required medication adjustments due to reduced kidney function
The VA granted service connection for diabetic nephropathy as secondary to diabetes mellitus with a 60% rating based on renal dysfunction with constant albuminuria and decreased kidney function.
Common Patterns of Secondary Kidney Conditions
| Primary Condition | Kidney Condition | Characteristics |
|---|---|---|
| Diabetes mellitus | Diabetic nephropathy | Progressive albuminuria, gradual GFR decline, often with retinopathy |
| Hypertension | Hypertensive nephrosclerosis | Gradual GFR decline, minimal proteinuria, vascular changes |
| Chronic pain requiring NSAIDs | NSAID nephropathy | Acute or chronic interstitial nephritis, papillary necrosis |
| Bipolar disorder requiring lithium | Lithium nephropathy | Nephrogenic diabetes insipidus, chronic tubulointerstitial disease |

Document all laboratory evidence of kidney dysfunction, particularly creatinine, GFR, and albumin/protein in urine, as well as any required treatments like dialysis, to support proper rating.
Urinary Tract Conditions Secondary to Neurological Disorders or Medication Effects
Urinary tract conditions—including neurogenic bladder, urinary incontinence, and urinary retention—frequently develop as secondary conditions to service-connected neurological disorders, spinal conditions, and medication side effects.
Medical Connection
The development of urinary tract conditions as secondary effects occurs through several mechanisms:
Secondary to Neurological Disorders
Neurological conditions affect urinary function through:
- Disruption of central control: Brain injuries affecting micturition centers
- Spinal cord injury: Interrupting neural pathways to bladder
- Peripheral neuropathy: Affecting sensory and motor nerves to bladder
- Autonomic dysregulation: Affecting bladder tone and sphincter coordination
- Multiple sclerosis plaques: Affecting spinal or brain control centers
Secondary to Medication Effects
Various medications can affect urinary function:
- Anticholinergics: Cause urinary retention
- Alpha-blockers: Can cause urinary incontinence
- Diuretics: Increase urinary frequency and urgency
- Sedatives: Reduce awareness of bladder filling
- Antidepressants: Many affect urinary function
- Calcium channel blockers: Can cause urinary retention
Case Study: Neurogenic Bladder Secondary to Lumbar Spine Condition
A veteran with service-connected lumbar degenerative disc disease with radiculopathy (40% rating) developed urinary retention and overflow incontinence. His successful secondary claim included:
- Urology evaluation diagnosing neurogenic bladder
- Urodynamic testing showing detrusor areflexia and high post-void residual

Ratings range from 0% to 60% based on specific symptoms and treatment requirements. Document all aspects of urinary dysfunction, particularly the need for catheterization, use of absorbent materials and frequency of changing, and any urinary frequency or obstructive symptoms to support proper rating.
Erectile Dysfunction Secondary to Diabetes, Vascular Conditions, or Medication Effects
Erectile dysfunction (ED)—the inability to achieve or maintain an erection sufficient for sexual performance—frequently develops as a secondary condition to service-connected diabetes, vascular conditions, neurological disorders, and medication side effects.
Medical Connection
The development of erectile dysfunction as a secondary condition occurs through several mechanisms:
Secondary to Diabetes Mellitus
Diabetes affects erectile function through:
- Endothelial dysfunction: Impairs nitric oxide-mediated vasodilation
- Microvascular disease: Affects small vessels in penile tissue
- Peripheral neuropathy: Affects nerves controlling erection
- Autonomic neuropathy: Disrupts neural control of erection
- Hormonal imbalances: Reduced testosterone levels
Secondary to Vascular Conditions
Vascular disorders affect erectile function through:
- Atherosclerosis: Reduces blood flow to penile arteries
- Hypertension: Damages endothelial function
- Venous leak: Inability to maintain blood in erectile tissue
- Endothelial dysfunction: Impairs vasodilation
- Shared risk factors: ED often precedes other vascular events
Secondary to Medication Effects
Various medications can cause erectile dysfunction:
- Antihypertensives: Especially beta-blockers and thiazide diuretics
- Antidepressants: Particularly SSRIs and SNRIs
- Antipsychotics: Through multiple mechanisms
- Antiandrogens: Used for prostate conditions
- Opioids: Affect hormonal balance
- H2 blockers: Some affect hormonal balance
Case Study: Erectile Dysfunction Secondary to Diabetes
A veteran with service-connected diabetes mellitus (40% rating) developed complete erectile dysfunction unresponsive to oral medications. His successful secondary claim included:
- Urology evaluation diagnosing organic erectile dysfunction
- Penile Doppler ultrasound showing reduced arterial flow
- Hormone testing showing normal testosterone levels
- Documentation of diabetic peripheral neuropathy
- Failed trials of PDE5 inhibitors (sildenafil, tadalafil)
- Urologist’s opinion stating that “the veteran’s erectile dysfunction is at least as likely as not caused by his service-connected diabetes mellitus, as evidenced by the concurrent development of peripheral neuropathy, vascular insufficiency on Doppler studies, and the absence of other risk factors”
- Evidence of psychological impact on marriage and self-esteem
The VA granted service connection for erectile dysfunction as secondary to diabetes mellitus with special monthly compensation for loss of use of a creative organ.
Common Patterns of Secondary Erectile Dysfunction
| Primary Condition | Mechanism for ED | Characteristics |
|---|---|---|
| Diabetes mellitus | Vascular and neurological | Gradual onset, often with other complications, poor response to oral medications |
| Hypertension | Vascular and medication effects | May improve with medication changes, vascular pattern on testing |
| PTSD/depression treated with SSRIs | Medication effects | Temporal relationship to medication, may improve with dose adjustment |
| Spinal cord injury | Neurogenic | Level of injury determines pattern, may have reflex erections without sensation |
| Prostate cancer treatment | Surgical, radiation, or hormonal | Immediate onset after surgery, gradual after radiation, hormonal effects |
Documentation Strategies
To establish erectile dysfunction as a secondary condition, focus on documenting:
- Urology evaluation and diagnosis
- Objective testing if performed:
- Penile Doppler ultrasound
- Nocturnal penile tumescence testing
- Hormone levels (testosterone, prolactin)
- Neurological testing
- Detailed symptom description:
- Complete vs. partial ED
- Gradual vs. sudden onset
- Presence of morning erections
- Ability to achieve vs. maintain erection
- For diabetes-related ED:
- Duration and control of diabetes
- Presence of other diabetic complications
- Temporal relationship to diabetes diagnosis
- For vascular-related ED:
- Vascular studies

- Specialist opinions addressing the causal relationship
- Research literature supporting the specific connection
Rating Consideration
Erectile dysfunction itself is typically rated at 0% under Diagnostic Code 7522 unless there is deformity of the penis with loss of erectile power, which warrants a 20% rating. However, erectile dysfunction usually qualifies for special monthly compensation (SMC) for loss of use of a creative organ. Document the complete inability to achieve an erection sufficient for sexual intercourse and failed treatments to support the SMC claim.
Female Reproductive Conditions Secondary to Endocrine Disorders or Medication Effects
Female reproductive conditions—including menstrual disorders, premature ovarian insufficiency, and fertility issues—can develop as secondary conditions to service-connected endocrine disorders and medication side effects.
Medical Connection
The development of female reproductive conditions as secondary effects occurs through several mechanisms:
Secondary to Endocrine Disorders
Endocrine conditions affect female reproductive function through:
- Hypothalamic-pituitary-gonadal axis disruption: Alters hormone signaling
- Thyroid dysfunction: Affects menstrual cycle and fertility
- Adrenal disorders: Alter sex hormone production
- Diabetes: Affects ovarian function and increases pregnancy complications
- Hyperprolactinemia: Suppresses ovulation
Secondary to Medication Effects
Various medications can affect female reproductive function:
- Chemotherapy: Can cause premature ovarian insufficiency
- Certain antipsychotics: Raise prolactin, disrupt menstruation
- Antiepileptic drugs: Some affect hormone metabolism
- Corticosteroids: Disrupt hypothalamic-pituitary function
- Opioids: Suppress hypothalamic-pituitary-gonadal axis
- Certain antidepressants: May affect sexual function and menstruation
Case Study: Premature Ovarian Insufficiency Secondary to Chemotherapy
A 32-year-old female veteran with service-connected Hodgkin’s lymphoma (in remission, 30% rating) underwent chemotherapy with alkylating agents. Six months after treatment, she developed amenorrhea, hot flashes, and was diagnosed with premature ovarian insufficiency. Her successful secondary claim included:
- Gynecology evaluation diagnosing premature ovarian insufficiency
- Laboratory evidence:
- Elevated FSH and LH levels
- Low estradiol levels
- Normal prolactin and thyroid function
- Oncology records documenting chemotherapy regimen known to cause ovarian damage
- Documentation of regular menstrual cycles prior to chemotherapy
- Reproductive endocrinologist’s opinion stating that “the veteran’s premature ovarian insufficiency is directly caused by chemotherapy for her service-connected Hodgkin’s lymphoma, as evidenced by the temporal relationship, her young age, the known gonadotoxic effects of her specific chemotherapy agents, and the absence of other risk factors”
- Evidence of infertility and need for hormone replacement therapy
- Documentation of psychological impact and quality of life effects
The VA granted service connection for premature ovarian insufficiency as secondary to treatment for service-connected Hodgkin’s lymphoma with a 30% rating based on symptoms requiring continuous treatment.
Common Patterns of Secondary Female Reproductive Conditions

|---|---|---|
| Cancer requiring chemotherapy | Premature ovarian insufficiency | Amenorrhea, elevated gonadotropins, menopausal symptoms, infertility |
| Hypothyroidism | Menstrual irregularities | Heavy or irregular periods, anovulation, infertility |
| Hyperprolactinemia from medications | Galactorrhea, amenorrhea | Nipple discharge, absent periods, infertility |
| Diabetes mellitus | Menstrual irregularities | Irregular cycles, PCOS-like features, fertility issues |
| Chronic opioid therapy | Hypogonadotropic hypogonadism | Low estrogen, amenorrhea, decreased libido |
Documentation Strategies
To establish female reproductive conditions as secondary, focus on documenting:

Rating Consideration
Female reproductive conditions are rated under various diagnostic codes (7610-7629) based on specific conditions and symptoms. Many conditions are rated based on whether symptoms require continuous treatment. Document all symptoms, treatment requirements, and functional impacts thoroughly to support proper rating. For conditions causing infertility, special monthly compensation for loss of use of a creative organ may be applicable.
Evidence Checklist & Documentation Strategies
Genitourinary Secondary Conditions Evidence Checklist
- Medical diagnosis of the secondary genitourinary condition
- Treatment records for the primary service-connected condition
- Specialist evaluations (urology, nephrology, gynecology)
- Laboratory evidence (kidney function, hormone levels)
- Imaging studies of relevant structures
- Specialized testing results (urodynamics, Doppler studies)
- Medication history showing drugs prescribed for service-connected conditions
- Baseline genitourinary function prior to primary condition
- Medical opinion linking the genitourinary condition to the primary condition
- Timeline showing primary condition preceded genitourinary symptoms
- Treatment requirements for the genitourinary condition
- Documentation of complications (infections, fertility effects)
- Functional impact assessment
- Psychological impact statement if applicable
- Personal statement describing how the primary condition led to genitourinary symptoms
- Relevant medical literature supporting the genitourinary connection
Effective Documentation Approaches
For genitourinary secondary conditions, these documentation strategies are particularly effective:
Specialist Involvement
Genitourinary conditions require specialist evaluation:
- Nephrologist for kidney conditions
- Urologist for urinary tract and male reproductive conditions
- Gynecologist for female reproductive conditions
- Reproductive endocrinologist for complex hormonal issues
- Neurourologist for neurogenic bladder
Objective Testing
Objective test results provide compelling evidence:
- For kidney conditions: Creatinine, eGFR, urinalysis, imaging
- For urinary conditions: Urodynamics, post-void residual, cystoscopy
- For erectile dysfunction: Doppler studies, hormone levels
- For female conditions: Hormone panels, ultrasound, specialized testing
Functional Impact Documentation
Document how genitourinary conditions affect function:
- For kidney disease: Fatigue, dietary restrictions, dialysis needs
- For urinary conditions: Frequency, pad usage, catheterization needs
- For erectile dysfunction: Relationship effects, psychological impact
- For female conditions: Pain, fertility effects, hormone replacement needs
Temporal Relationship
Document the timeline clearly:
- Baseline genitourinary function before primary condition
- Onset of primary condition or start of medication
- First appearance of genitourinary symptoms
- Progression of genitourinary condition
- Response to treatment of primary condition
Expert Tip
For genitourinary conditions, particularly those related to medications, obtaining baseline testing results from before the medication was started can be extremely valuable evidence. If available, include pre-treatment laboratory values, imaging studies, or urodynamic testing showing normal function, followed by the post-treatment testing showing the changes. This clear “before and after” evidence strongly supports the causal relationship between the medication and the genitourinary condition.
