Why Urogynecologists Get Sued: The Mesh, the Ureter, and the Fistula

By John Mahoney · June 2026 · 8 min read

Urogynecology — female pelvic medicine and reconstructive surgery — is a small subspecialty with an outsized litigation footprint, and the reason is structural. Its core operations sit at the crossing of the bladder, the ureters, and the vagina, so a single surgical misstep can produce a permanent, disabling injury. On top of that anatomy sits the largest medical-device mass tort in modern memory: transvaginal synthetic mesh. An attorney who screens a urogynecology file the way they screen a routine gynecology file will misjudge both the catastrophic-injury risk and the device-and-consent overlay that decides so many of these cases. This guide explains where urogynecology liability actually lives, the cannot-miss failures behind it, and what separates a strong case from a weak one — for plaintiff and defense med-mal attorneys.

Disclaimer: This article is for informational purposes only and does not constitute legal advice. The patterns below draw on closed-claims experience, the transvaginal-mesh litigation record, and surgical-complication literature that span different eras and definitions; treat them as directional, verify against the controlling jurisdiction, and value any individual case on its own record.

The Frequency-and-Severity Reality

By raw frequency, the surgeons who do this work face an exposure typical of operative gynecology and urology, which sit in the moderate-risk band of medicine rather than the high-frequency specialties. But frequency is the wrong lens for urogynecology, because the severity profile is what drives the litigation. The procedures here — prolapse repair, sling and incontinence surgery, fistula repair — carry a real rate of injury to adjacent organs, and when those injuries occur and are not recognized, the resulting harm is often permanent: chronic pelvic pain, dyspareunia, incontinence, recurrent infection, or a fistula that requires multiple reoperations.

Layered on top of ordinary surgical exposure is the transvaginal-mesh mass tort, which is reported to have produced one of the largest medical-device litigation settlements on record, with manufacturer payouts commonly described in the billions and tens of thousands of individual claims resolved. That backdrop reshapes the severity math for any case touching synthetic mesh: the device claims against manufacturers are largely product-liability matters, but the parallel professional-negligence questions — whether mesh was appropriately indicated, properly placed, and adequately consented — sit squarely with the surgeon. The screening lesson is that urogynecology hides a high-severity tail behind moderate frequency, and two of its signature injuries — the unrecognized ureteral injury and the post-operative fistula — are among the most valuable individual claims in pelvic surgery.

The Dominant Allegation Types

Urogynecology claims cluster into a device group, a surgical-injury group, and a consent thread that runs through both:

• Synthetic / transvaginal mesh complications — mesh erosion or exposure into the vagina, bladder, or urethra, chronic pelvic pain, and dyspareunia. This is the signature allegation type, and it carries both a professional-negligence theory and the mass-tort backdrop against manufacturers.
• Ureteral and bladder injury during surgery — injury to the ureter or bladder during prolapse repair, hysterectomy, or sling placement, with the negligence often framed not as the injury itself but as the failure to recognize and repair it intraoperatively.
• Post-operative fistula — vesicovaginal and ureterovaginal fistula, a high-severity outcome that frequently signals an unrecognized intraoperative injury and drives some of the largest individual payouts.
• Persistent or worsened incontinence and voiding dysfunction — failed or over-corrected slings, urinary retention, de novo or worsened incontinence, and the need for revision surgery.
• Bowel injury — enterotomy or rectal injury during pelvic dissection, again with the decisive question being timely recognition.
• Lack of informed consent / failure to disclose mesh risks and alternatives — central to nearly every mesh case and a frequent stand-alone or paired theory.

The structural point: by theme, urogynecology splits into device-driven claims and surgical-injury claims, and the consent record runs through both. Any intake should be triaged first on which side of that line it sits, and second on whether a synthetic mesh product is involved — because the merit analysis, the experts, the parties, and the damages shift sharply depending on the answer.

The Cannot-Miss Conditions and Failures

The conditions and failures that drive urogynecology litigation are:

• Transvaginal mesh erosion / exposure — and the consent that should have preceded it. Mesh that erodes into the vaginal wall, bladder, or urethra produces chronic pain, dyspareunia, infection, and the need for revision or removal. The recurring failure is twofold: a placement or indication that was not appropriate, and an informed-consent record that did not disclose the specific mesh risks and the non-mesh alternatives.
• Unrecognized ureteral injury. The highest-leverage surgical failure in the specialty. A ureter injured during prolapse or incontinence surgery that is not identified and repaired during the operation often presents days later as obstruction, leak, or fistula, converting a recognized-and-repaired complication into a negligence claim.
• Unrecognized bladder injury. Similar logic — a cystotomy or sling perforation not identified and addressed intraoperatively, sometimes detectable by cystoscopy that was not performed or not documented.
• Vesicovaginal and ureterovaginal fistula. A post-operative fistula is both a devastating outcome and a marker that an earlier injury was missed; these cases combine high damages with a strong intraoperative-recognition theory.
• Persistent incontinence and voiding dysfunction — retention, obstruction, or worsened leakage after a sling, often requiring revision, with the dispute centered on technique and on whether the outcome was a disclosed risk.
• Bowel injury — enterotomy or rectal injury during pelvic dissection, again turning on whether it was recognized and managed at the time.

For the surgical side, the single most actionable screening question is the recognition question: was the adjacent-organ injury identified and repaired during the operation, and does the record show the intraoperative checks — cystoscopy, ureteral assessment — that should have caught it? A recognized-and-repaired injury is usually a defensible complication; a missed one that surfaces as a fistula is usually a paid claim. For the mesh side, the decisive question is the consent record: did it specifically disclose mesh erosion, chronic pain, dyspareunia, and the available non-mesh alternatives?

The Contributing Factors That Drive Payouts

Across urogynecology claims, the recurring contributing factors are:

• Surgical technique and adjacent-organ injury — injury to the ureter, bladder, or bowel during dissection and device placement, the most common high-severity error, with the realized payout driven less by the injury than by the failure to recognize it.
• Intraoperative recognition and the cystoscopy record — the costliest factor in the surgical claims: whether the surgeon performed and documented the intraoperative checks that catch a ureteral or bladder injury before the patient leaves the table.
• Device selection and indication — whether synthetic mesh was the appropriate choice for the patient and the prolapse, an issue amplified by the mass-tort backdrop and by evolving guidance on transvaginal mesh for prolapse.
• Informed consent and disclosure of mesh risks and alternatives — the decisive lever in mesh cases: failure to convey the specific, material risks of mesh and the existence of non-mesh repairs converts an accepted-risk complication into a consent claim.
• Documentation — incomplete operative notes, absent cystoscopy findings, thin consent forms, and gaps in post-operative follow-up that weaken the defense when a delayed injury surfaces.

Two of these are urogynecology-specific levers. The first is the intraoperative-recognition record: in an unrecognized-injury or fistula case, the line between a defensible complication and a paid claim is often whether the operative note and cystoscopy findings show the surgeon looked for and ruled out adjacent-organ injury. The second is the mesh-consent record: in a mesh case, the chart's disclosure of erosion, chronic pain, dyspareunia, and the non-mesh alternative frequently decides the case before technique is ever reached. Documentation rarely creates liability here, but it consistently decides whether a claim is paid.

Strong Case vs. Weak Case in Urogynecology Malpractice

The same factors grade the file, and the framing is useful to both sides.

What makes a urogynecology case strong (plaintiff) / dangerous (defense)

• An adjacent-organ injury — ureter, bladder, or bowel — that was not recognized at surgery and presented later as obstruction, leak, or fistula, with an operative note that shows no cystoscopy or intraoperative assessment was performed or documented.
• A vesicovaginal or ureterovaginal fistula requiring reoperation, paired with a clean theory that an intraoperative injury was missed.
• A synthetic-mesh erosion or chronic-pain case with an informed-consent record that did not specifically disclose mesh erosion, dyspareunia, and the available non-mesh alternatives.
• A mesh placement whose indication is hard to defend under current guidance on transvaginal mesh for prolapse, with thin documentation of the decision.

What makes a urogynecology case weak (plaintiff) / defensible (defense)

• An adjacent-organ injury that was recognized intraoperatively, documented, and repaired at the time — with a cystoscopy or ureteral assessment recorded — framing the event as a known, properly managed complication rather than negligence.
• A mesh or sling outcome that was a disclosed, material risk, with a specific informed-consent record covering erosion, pain, dyspareunia, and non-mesh alternatives, supporting an accepted-risk defense.
• A patient whose record shows non-adherence, missed post-operative follow-up, or risk factors that drove the complication independent of technique.
• A procedure performed to current indication standards by an appropriately trained surgeon, with a complete operative note, documented intraoperative checks, and informed consent.

Urogynecology rewards a fast, two-axis triage. On the surgical side, the case lives or dies on the intraoperative-recognition record and the causation chain from a missed injury to the fistula or permanent dysfunction. On the device side, it turns on indication and — above all — on whether the consent record specifically disclosed the mesh risks and the alternatives. Whichever side you are on, grading the file means matching the right model to the right claim, reading the operative note and the consent form as closely as the injury itself, and pressure-testing the female-pelvic-medicine expert who will carry it.

Bottom Line

Urogynecologists get sued at a moderate frequency but carry a sharp severity tail, because their core operations cross the bladder, ureters, and vagina and because the specialty sits under the largest medical-device mass tort in recent memory. Most of the dollars concentrate in a handful of patterns: transvaginal mesh erosion and chronic pain, the unrecognized ureteral or bladder injury that surfaces as a fistula, and persistent incontinence after a failed sling. The cannot-miss facts are the adjacent-organ injury that was never recognized intraoperatively, the post-operative fistula that signals a missed injury, and the mesh-consent record that did not disclose erosion, dyspareunia, and the non-mesh alternatives. Whether you are screening these cases for the plaintiff or defending them, triage first to the right model — surgical injury or device-and-consent — and grade the file on the operative note, the intraoperative-recognition record, and the documented consent, not on the visible injury alone.
