When years of pelvic pain led to kidney damage — could delayed endometriosis diagnosis have been prevented?

For many women, the path to an endometriosis diagnosis stretches across years of appointments, dismissed symptoms, and referrals that never came. By the time someone finally looks closely enough, the damage has already spread — sometimes reaching the kidneys. If that happened to you, you are not alone, and you are not wrong to ask whether it should have been caught sooner.

• 1
  Symptoms beginPelvic pain, painful periods, and bladder pressure appear — often in the teens or early twenties. Many clinicians attribute these to normal menstruation.
• 2
  Repeated GP visitsThe patient returns multiple times over months or years. Clinicians prescribe pain relief or the oral contraceptive pill without investigating the underlying cause.
• 3
  No specialist referralDespite worsening symptoms, no gynaecologist or urologist reviews the patient. Imaging is either not ordered or does not capture deep infiltrating disease.
• 4
  Ureteric involvement developsEndometriosis tissue grows onto or around the ureter — the tube connecting the kidney to the bladder. The ureter narrows or becomes blocked. The kidney begins to swell.
• 5
  Diagnosis finally madeA scan or surgery reveals hydronephrosis — a swollen, obstructed kidney. By this point, permanent kidney damage may already have occurred.

A common pattern — where care can break down

Endometriosis is a condition where tissue similar to the lining of the uterus grows outside it — on the ovaries, bowel, bladder, and sometimes the ureters. The ureters are the narrow tubes that carry urine from each kidney down to the bladder. When endometriosis grows on or around a ureter, it can compress or invade the tube, blocking the flow of urine. That blockage causes the kidney to swell — a condition called hydronephrosis.

Hydronephrosis means the kidney fills with backed-up urine because the ureter cannot drain it properly. Over time, that pressure damages the kidney tissue. If the obstruction continues long enough, the kidney can lose function permanently. This is not a rare or unpredictable complication — it is a known consequence of untreated deep infiltrating endometriosis.

The failures that allow this to happen

Several distinct failures in clinical care allow ureteric endometriosis to reach this point. Each one represents a moment where a different decision could have changed the outcome.

Dismissing pelvic pain as normal. Many clinicians tell patients that painful periods are simply part of being a woman. This response delays investigation. A competent clinician should consider endometriosis when a patient reports cyclical pelvic pain that disrupts daily life — especially when that pain persists across multiple consultations.

Failing to refer to a specialist. General practitioners manage many conditions, but deep infiltrating endometriosis requires specialist assessment. A gynaecologist — and in some cases a urologist — should review patients with persistent pelvic symptoms. When a GP manages these symptoms alone for years without referring, the window for early intervention closes.

Ordering inadequate imaging. A standard pelvic ultrasound often misses deep infiltrating endometriosis, particularly disease involving the ureter. A competent clinician who suspects endometriosis should consider MRI or transvaginal ultrasound performed by a specialist sonographer. Ordering only a basic scan and reporting it as normal does not rule out the disease.

Missing ureteric involvement at surgery. Some patients do reach surgery, but the operating surgeon fails to identify or address ureteric endometriosis. Surgeons treating endometriosis must assess the ureters carefully. Leaving ureteric disease untreated during an otherwise adequate procedure is a failure of surgical care.

Failing to monitor kidney function. Once ureteric endometriosis is known or suspected, the treating team must monitor kidney function. Failing to order renal imaging or blood tests — and failing to act on abnormal results — allows silent kidney damage to progress. The Australian Commission on Safety and Quality in Health Care sets clear expectations around monitoring and follow-up in complex chronic conditions.

When things start to go wrong — recognising the warning signs

Ureteric obstruction from endometriosis is often silent in its early stages. The kidney can lose a significant portion of its function before a patient feels anything specific. That silence is part of what makes delayed diagnosis so damaging — and so legally significant.

Any one of these symptoms in isolation might have an innocent explanation. But a clinician who sees several of these symptoms together — especially in a woman of reproductive age — should investigate endometriosis and its possible effect on the urinary tract. Failing to connect these dots is a clinical failure, not an acceptable oversight.

Understanding endometriosis and ureteric obstruction — what normally happens

Endometriosis affects roughly one in nine Australian women of reproductive age. Despite how common it is, the average time from first symptoms to diagnosis in Australia has historically been around seven years. That delay is not inevitable — it reflects a pattern of under-investigation and normalisation of pain.

Ureteric endometriosis is less common than ovarian or peritoneal disease, but it is well documented. Clinicians who specialise in endometriosis know to look for it. The standard of care for a patient with suspected or confirmed endometriosis includes assessing the urinary tract — particularly if the patient reports urinary symptoms or if imaging suggests disease near the pelvic sidewall.

When a clinician identifies ureteric involvement early, treatment options are available. A urologist can place a stent — a small tube — inside the ureter to keep it open while the endometriosis is treated. Surgery can remove the endometriosis tissue and, if necessary, repair the ureter. Early intervention preserves kidney function. Late intervention, or no intervention, does not.

Why this matters legally

Every doctor, specialist, and hospital in Australia owes their patients a duty of care. That duty means the clinician must provide treatment that meets the standard a reasonably competent clinician in the same field would have provided. When care falls below that standard and causes harm, the law may treat that as negligence.

Not every bad outcome is negligence. Endometriosis is a complex condition, and some patients develop ureteric involvement even with good care. The legal question is not whether the outcome was bad — it is whether the clinician’s decisions and actions met the standard expected of a competent practitioner.

A seven-year delay in diagnosis, with no specialist referral and no imaging of the urinary tract, is a different situation from a case where a specialist reviewed the patient regularly and the disease progressed despite appropriate treatment. The first scenario raises serious questions about the standard of care. The second may not.

When ureteric obstruction from endometriosis may amount to medical negligence

The NSW Civil Liability Act 2002 is the main law governing personal injury claims in New South Wales. It sets out the rules for proving negligence, including what standard of care applies and how courts assess whether a clinician’s conduct was reasonable.

Several specific scenarios may give rise to a negligence claim in this context.

If a GP saw you repeatedly for pelvic pain and never referred you to a gynaecologist, that failure to refer may constitute a breach of duty — particularly if your symptoms were persistent, cyclical, and consistent with endometriosis.

If a gynaecologist diagnosed endometriosis but never assessed your urinary tract, and ureteric disease later caused kidney damage, the failure to investigate a known complication of the condition may be legally significant.

If a surgeon operated for endometriosis but missed or ignored ureteric involvement, and you later required further surgery or lost kidney function, the surgical team’s failure to identify and treat the disease may amount to negligence.

If abnormal kidney function results appeared in your medical records and no clinician acted on them, that failure to respond to documented evidence of harm is a serious breach of the standard of care.

In each scenario, the key question is whether a competent clinician in the same position would have acted differently — and whether acting differently would have prevented the kidney damage you suffered.

When harm becomes long-term or permanent

Kidney damage from ureteric obstruction is not always reversible. The longer the obstruction continues, the more kidney tissue dies. Some patients lose partial function in one kidney. Others lose the kidney entirely. A small number develop bilateral obstruction — affecting both kidneys — which can lead to kidney failure requiring dialysis or transplant.

The physical consequences extend beyond the kidney itself. Many patients require multiple surgeries — ureteric stenting, ureteroplasty, or nephrectomy (removal of the kidney). Recovery from these procedures is significant. Some patients live with a stent permanently, which causes ongoing discomfort and requires regular replacement under anaesthetic.

Psychological and financial consequences

The psychological impact of a preventable injury is substantial. Many patients describe grief, anger, and a deep sense of betrayal — particularly when they had raised their symptoms repeatedly and been dismissed. Anxiety about future kidney function, fertility, and further surgery is common. Some patients develop depression or post-traumatic stress responses.

Financially, the consequences compound over time. Lost income during recovery, ongoing specialist appointments, imaging, stent replacements, and medication costs accumulate. Patients who lose significant kidney function may face restrictions on work capacity, travel, and lifestyle that persist for decades.

What compensation can cover in ureteric obstruction and endometriosis cases

In New South Wales, a successful medical negligence claim can cover several categories of loss. These include pain and suffering, lost income (past and future), the cost of past and future medical treatment, and the cost of care and assistance at home.

In cases involving permanent kidney damage, compensation amounts can be substantial — particularly where the patient is young, loses significant earning capacity, and requires ongoing medical management for decades.

Each case is assessed on its own facts. These figures are general ranges only. Cases involving permanent loss of kidney function, multiple surgeries, and long-term income loss often fall in the higher ranges.

Time limits apply to medical negligence claims in New South Wales. Generally, a claim must begin within three years of the date the person knew — or ought reasonably to have known — that they had suffered harm as a result of negligent care. Waiting too long can extinguish the right to claim entirely.

Bringing it together — do the pieces fit?

Medical negligence cases involving delayed endometriosis diagnosis and kidney damage are complex. But complexity does not mean the pieces cannot be examined clearly. The starting point is always the same: what happened, what should have happened, and whether the gap between those two things caused your harm.

Understanding how a claim works — and what evidence matters — helps you approach this process with clarity rather than anxiety. Reframe Legal — How Medical Negligence Claims Work in NSW explains the process in plain language.

You don’t need certainty to understand your position

Many people who have experienced this kind of harm spend years doubting themselves. Doctors are trusted figures. When they dismiss your symptoms, it is natural to wonder whether you were overreacting. When harm eventually occurs, it is natural to wonder whether you somehow missed something yourself.

Legal clarity does not require certainty. Nobody expects you to know whether your care was negligent — that is a question for medical experts and lawyers to assess. What matters is that you have the information to decide whether your situation is worth examining.

Consent is also relevant in some of these cases. If a clinician performed a procedure without explaining the risk of ureteric injury, or without telling you that your endometriosis had spread to your urinary tract, that failure to inform may itself be a legal issue. Reframe Legal — Informed Consent and Medical Negligence explains how consent failures interact with negligence claims.

About the lawyer behind this article

Dr Rosemary Listing is a NSW lawyer with a PhD focused on medical negligence. Her academic and clinical background gives her an unusually detailed understanding of how medical decisions are made — and where they fall short.

Dr Listing has worked with clients whose endometriosis went undiagnosed for years, and whose kidney damage was discovered only after the window for prevention had closed. She understands the specific clinical failures that allow ureteric obstruction to develop — and how those failures translate into legal questions about the standard of care.

In her experience, the harm in these cases rarely comes from the endometriosis alone. It comes from the years of delay — the dismissed appointments, the inadequate imaging, the referrals that never happened. That delay is where the legal analysis begins.

Clients who approach Dr Listing are not looking to blame anyone. Most simply want to understand what happened to them and whether the care they received met the standard they were entitled to expect.

Dr Listing’s role is to examine the clinical record carefully, obtain expert medical opinion, and give an honest assessment of whether the standard of care was met — and whether the harm you suffered was a consequence of that failure.
