EAU Entrance Exam common mistakes
EAU Entrance Exam · Understand the traps and how to avoid them.
On stone-imaging questions, choosing CT KUB as the first-line study for a febrile patient with suspected obstructing stone, instead of recognising the need for urgent decompression and imaging that evaluates the whole urinary tract (or ultrasound-first in pregnancy).
Candidates memorise 'non-contrast CT is the gold standard for stones' as a blanket rule and apply it regardless of the clinical context of sepsis, pregnancy, or renal impairment, where the decision that matters is drainage, not stone detection.
What to do instead
Before answering, classify the scenario: afebrile stable stone, febrile obstructed infected system, pregnancy, or renal failure. For the febrile obstructed system, prioritise resuscitation plus urgent decompression (nephrostomy or stent) and reserve definitive stone treatment for after infection control; for pregnancy, start with ultrasound and reserve MRI if needed.
Assigning a fixed number of shockwave sessions or a rigid stone-size threshold to SWL versus ureteroscopy versus PCNL, rather than weighing stone density, location, skin-to-stone distance, and patient factors.
Revision guides compress decision-making into memorised cut-offs (for example 'under 10 mm means SWL'), and candidates reproduce the number without the modifiers that examiners test in the vignette.
What to do instead
Build each answer from the four levers: stone burden and density (Hounsfield units), location and anatomy, patient habitus and skin-to-stone distance, and patient preference. State explicitly which lever changes the recommendation in the stem, and remember lower-pole stones with steep infundibulopelvic angle or long skin-to-stone distance favour ureteroscopy over SWL.
Staging muscle-invasive bladder cancer from a TURBT specimen alone and proceeding to radical cystectomy without giving neoadjuvant cisplatin-based chemotherapy or confirming nodal status.
Candidates treat the TURBT histology as the final word and forget that staging is clinical and that a re-resection is mandatory for T1 or incomplete resection; they also underweight the survival benefit of neoadjuvant chemotherapy in cisplatin-eligible patients.
What to do instead
For every muscle-invasive scenario, state the pathway explicitly: restage with imaging of chest, abdomen and pelvis, confirm fitness for cisplatin, offer neoadjuvant cisplatin-based combination chemotherapy before cystectomy or radiotherapy, and perform re-TURBT when the initial resection was incomplete or the tumour is T1.
Managing an elevated PSA by immediate prostate biopsy in a patient with a treatable cause (urinary infection, recent catheterisation, ejaculation, cycling) instead of repeating PSA after treatment and using risk-adjusted pathways.
The reflex 'high PSA equals biopsy' shortcut ignores the many benign causes of elevation and the modern pathway of multiparametric MRI before biopsy, which candidates under-apply.
What to do instead
Always ask what could falsely elevate PSA and whether the value should be repeated after an appropriate interval and treatment of infection. Then describe the modern sequence: risk assessment (PSA density, family history, DRE), multiparametric MRI, and targeted plus systematic biopsy if indicated.
Treating every man with lower urinary tract symptoms as having benign prostatic obstruction and starting an alpha-blocker without assessing post-void residual, renal function, or the possibility of an underlying neurological or diabetic cause.
Candidates anchor on the most common diagnosis and skip the structured assessment of storage versus voiding symptoms, which the exam tests through atypical presentations.
What to do instead
Work through a fixed sequence: symptom pattern and validated score, urinalysis, flow rate with post-void residual, renal function, and examination. Consider detrusor underactivity, neurogenic bladder, urethral stricture, and medication effects before labelling it benign prostatic obstruction, and match treatment to the dominant symptom type.
Prescribing antibiotics for asymptomatic bacteriuria in a catheterised or elderly patient, or treating a positive urine culture without pyuria and clinical signs, instead of distinguishing colonisation from infection.
The presence of bacteria in a culture feels like proof of infection, and candidates conflate microbiological findings with clinical disease, a distinction the exam deliberately probes.
What to do instead
Apply the rule that asymptomatic bacteriuria is not treated except in defined situations such as pregnancy or before invasive urological procedures with mucosal trauma. For catheterised patients, require clinical signs plus pyuria before treating, and specify culture before antibiotics and catheter change or removal when relevant.
In a child with a febrile urinary tract infection, ordering a full battery of imaging for every age and sex instead of applying age- and risk-stratified protocols, and missing the timing of the ultrasound.
Candidates memorise 'febrile UTI means full workup' and cannot rank which investigation answers which question, so they over-investigate low-risk children and under-investigate those with atypical or recurrent infection.
What to do instead
Separate the questions: ultrasound answers structural anomaly and should follow the acute infection, while voiding cystourethrography or dimercaptosuccinic acid scanning answers reflux and scarring and is reserved for atypical, recurrent, or febrile infections in defined age groups. State the indication, not just the test name.
On undescended testis, recommending hormonal therapy or delaying orchidopexy beyond the first year, and failing to distinguish a retractile from a truly undescended testis on examination.
Outdated teaching about hormonal treatment persists in candidates' memory, and the examination distinction between retractile and undescended is a skill rarely rehearsed from text.
What to do instead
Anchor on the current standard: refer by around six months and perform orchidopexy within the first year to 18 months, with no role for hormonal therapy. Describe the examination manoeuvre that distinguishes retractile from undescended, and note that a non-palpable testis needs laparoscopy when imaging is unhelpful.
In erectile dysfunction, prescribing a phosphodiesterase-5 inhibitor without checking for contraindication with nitrates and without addressing the cardiovascular risk that the symptom signals.
Candidates focus on the drug that works and treat the sexual symptom in isolation, missing that erectile dysfunction is a marker of vascular disease and that the nitrate interaction is absolute.
What to do instead
For every erectile dysfunction question, state the contraindication check first, then the cardiovascular risk assessment and lifestyle modification, then the treatment ladder. Mention that a patient who fails oral therapy needs investigation of the cause rather than an automatic switch to injection therapy.
Evaluating blunt renal trauma with immediate CT in an unstable patient, or failing to apply the principle that haemodynamic stability, not grade, determines whether intervention or observation is chosen.
Candidates equate high injury grade with the need for surgery and low grade with safety, forgetting that the decision hinges on the patient's physiology and that unstable patients may need immediate operative control rather than a scan.
What to do instead
State the stability of the patient first, then the imaging and management consequence. Remember that most blunt renal injuries, including high-grade ones, are managed non-operatively when stable, that a haemodynamically unstable patient goes to intervention rather than the scanner, and that the same logic governs the choice between angioembolisation and surgery.
