ABOG Urogynecology and Reconstructive Pelvic Surgery common mistakes
ABOG Urogynecology and Reconstructive Pelvic Surgery · Understand the traps and how to avoid them.
Choosing a surgery for apical prolapse without first asking whether the apex is the dominant compartment and whether the patient has occult stress incontinence, then answering the management question as if anterior repair alone were sufficient.
Candidates pattern-match the visible bulge to the anterior wall and forget that most anterior and posterior prolapse with a widened hiatus has an apical component that must be addressed, and they skip the preoperative reduction stress test in advanced prolapse.
What to do instead
Before answering any surgical planning item, state the dominant compartment, the POP-Q stage, and whether occult SUI was unmasked by reduction; if the apex descends, commit to an apical suspension (sacrocolpopexy or native-tissue suspension) and address continence separately.
Confusing POP-Q points and reference values, for example reporting point C as the leading edge of the cervix rather than the most dependent point of the cervix or vaginal vault, or misassigning the hymen as the fixed reference.
The POP-Q grid is memorized as a diagram rather than as a set of definitions relative to a fixed landmark, and negative values in front of the hymen are misread as less severe than positive values.
What to do instead
Rehearse the definitions aloud: hymen is zero, points above the hymen are negative, C is the most dependent edge of the cervix or vault, and stage is assigned from the most prolapsed point, not from the compartment you think is worst.
Interpreting a urodynamics tracing by its pressure values alone, calling detrusor overactivity when the rise is actually abdominal straining or calling obstruction when the detrusor pressure is high but flow is normal.
Candidates read the detrusor channel in isolation and do not mentally subtract the abdominal (rectal) channel, and they apply nomogram cutoffs without checking whether the study is artifact-free and the volumes are physiologic.
What to do instead
For every tracing, first confirm subtracted detrusor pressure equals vesical minus abdominal, check that cough spikes appear on both channels, then classify by detrusor pressure at maximum flow combined with the flow curve and the clinical picture.
Treating mixed urinary incontinence with surgery first and expecting the urge component to resolve, rather than counseling and treating the OAB component before or alongside the stress procedure.
The stress component is easier to measure and the patient's chief complaint anchors the answer, so the urgency component is underweighted even though persistent postoperative urgency is a leading cause of dissatisfaction.
What to do instead
When both components are present, quantify the bother of each, offer behavioral and pharmacologic therapy for urgency first or concurrently, and set explicit expectations that the stress procedure will not reliably cure urge leakage.
Recommending mesh-augmented repair or a synthetic graft in a patient with a contaminated field, prior mesh complications, or a vaginal epithelial compromise without weighing graft type against vascularity and infection risk.
Candidates equate 'durable repair' with 'use mesh' and do not screen for the contraindications that change the biomaterial choice, and they conflate biologic grafts with synthetic mesh in terms of evidence and risk.
What to do instead
Before selecting a graft, screen for infection, poor vaginal epithelium, immunosuppression, and prior mesh erosion; state the indication, then choose native tissue, biologic, or synthetic based on that screen and the level of evidence for the specific repair.
Managing postoperative voiding dysfunction or urinary retention after incontinence surgery by prolonged catheter drainage alone, without evaluating for obstruction, hematoma, or unrecognized bladder injury.
Retention after a sling is assumed to be transient edema, so the candidate answers 'continue catheter' and never considers the reversible causes or the need for a voiding trial with residual measurement.
What to do instead
Structure the answer as assess first (residual volume, exam for hematoma or sling tension, imaging if needed), then temporize with clean intermittent catheterization, and only then consider sling loosening or takedown if obstruction is confirmed.
Attributing fecal incontinence in an older woman to sphincter injury alone and proceeding to sphincteroplasty without excluding overflow from fecal impaction, irritable bowel, or a defecatory disorder.
The obstetric history is salient and drives the answer, so the candidate skips the anorectal physiology and the medication and bowel-habit history that identify reversible and non-sphincter causes.
What to do instead
For every fecal incontinence item, run through the differential in order: impaction and overflow, diarrheal and irritable causes, then structural sphincter defect confirmed by endoanal imaging and manometry before offering repair.
Missing a sacral or pudendal neuropathy as the explanation for combined urinary and fecal dysfunction, or failing to recognize that a defecatory disorder with paradoxical contraction is treated with biofeedback rather than surgery.
Neurophysiology is treated as background reading, so neurogenic and functional causes are not linked to the presenting pelvic floor symptoms, and dyssynergic defecation is mistaken for prolapse.
What to do instead
When urinary and anorectal symptoms coexist, ask about sacral nerve function (sensation, anal wink, bulbocavernosus reflex) and order manometry with balloon expulsion before any surgical recommendation; paradoxical contraction points to pelvic floor retraining.
Answering a biostatistics item by intuition, for example calling a statistically significant result clinically important, misreading a confidence interval that crosses one, or confusing sensitivity with positive predictive value.
Candidates treat study design and test characteristics as low-yield and do not translate the numbers into the clinical scenario, so they default to the most familiar-sounding option.
What to do instead
For each study item, identify the design, the effect measure, and whether the interval excludes the null; for each diagnostic item, write the 2x2 table from the stem before choosing among sensitivity, specificity, and predictive values.
Operating on a patient with a congenital anomaly or a special population using standard adult assumptions about anatomy, continence mechanism, or mesh use, without adjusting for the altered anatomy and the longer lifetime risk.
These cases appear rarely in practice, so the candidate applies the usual prolapse or incontinence algorithm and ignores the anomalous anatomy, the possibility of a neurogenic bladder, and the need for lifelong follow-up.
What to do instead
For special-population items, first define the anatomy and the continence mechanism present, then choose the least destructive durable option, avoid mesh where tissue quality and follow-up are uncertain, and build in surveillance for upper tract and neurologic change.
