Preoperative Evaluation and Surgical Decision-Making for Benign Prostatic Hyperplasia

Required Preoperative Evaluation

The American Urological Association recommends that patients with significant prostate enlargement and elevated post-void residual undergo a mandatory preoperative evaluation, including medical history, AUA-Symptom Index, urinalysis, prostate size assessment, post-void residual measurement, and consideration of uroflowmetry 1, 2, 3, 4
Urinalysis must be performed to rule out infection or other pathology in patients with benign prostatic hyperplasia 1, 2, 3, 4
Prostate size and shape assessment via transabdominal or transrectal ultrasound, cystoscopy, or existing cross-sectional imaging should be considered prior to surgical intervention for BPH 1, 2, 3, 4
Post-void residual assessment is crucial in evaluating patients with BPH, as it helps identify those with significant bladder dysfunction 1, 2, 3, 4
Uroflowmetry should be considered prior to surgical intervention to assess urinary flow rates and identify potential obstruction 1, 2, 3, 4

Surgery is appropriate for patients with moderate-to-severe lower urinary tract symptoms, acute urinary retention, or other BPH-related complications, according to the American Urological Association 5
Patients with recurrent urinary retention, recurrent urinary tract infections, bladder stones, or renal insufficiency due to obstruction are best treated surgically 5

A post-void residual volume >200-300 mL is considered clinically significant and may indicate bladder dysfunction 6, 7
A post-void residual volume ≥350 mL strongly indicates bladder dysfunction and may herald disease progression 6

The American Urological Association recommends proceeding directly to surgical evaluation if the patient has acute urinary retention refractory to catheter trial, recurrent urinary retention, recurrent urinary tract infections, bladder stones, or renal insufficiency due to obstruction 5

Patients must be provided with the risk/benefit profile for all treatment options, including surgical treatment, to make informed decisions regarding their treatment, according to the American Urological Association 1, 2, 3, 4
Counseling about sexual side effects, symptom reduction expectations, and retreatment rates for various procedures is essential in shared decision-making 1, 2, 3, 4
