What tests should be done before prostate surgery?

Good prostate surgery starts with the right diagnosis. The aim is not simply to measure prostate size, but to understand the degree of obstruction, bladder function, complications and whether another condition could be contributing to urinary symptoms.

The core evaluation

A typical assessment starts with a detailed urinary and medical history, medication review, examination and a structured assessment of symptom severity and bother. Urinalysis is important. PSA is used when prostate-cancer assessment or treatment decision-making would be affected. Kidney function is particularly relevant when surgery is being considered or renal impairment is suspected.

Ultrasound, prostate size and residual urine

Imaging helps define prostate size and anatomy and can assess the bladder, kidneys and post-void residual urine. A large residual may reflect obstruction, weak bladder contraction, or both; it should therefore be interpreted in context rather than as a stand-alone number.

Uroflowmetry

Uroflowmetry measures the urinary flow pattern and maximum flow rate. A low flow can support the presence of a voiding problem, but by itself cannot reliably distinguish prostate obstruction from reduced bladder contractility. Voided volume and the shape of the flow curve matter.

Not every patient needs every test. Cystoscopy, MRI and formal urodynamics are useful in selected situations, not automatically before every prostate operation.

When are additional tests useful?

Cystoscopy may be appropriate where urethral stricture, bladder pathology or haematuria is a concern. Urodynamics can be valuable when the cause of symptoms is uncertain, bladder weakness is suspected, previous treatment has failed, or the expected benefit from outlet surgery is unclear.

The question we are trying to answer

The pre-operative work-up should establish: Is the prostate actually causing significant obstruction, what has that obstruction done to the bladder and urinary tract, and is surgery likely to improve this patient's problem?
