A - IPSS of 18

Indications for PAE for lower urinary tract symptoms:

• International Prostate Symptom Score (IPSS) > 12-14. The IPSS is a score derived from a questionnaire about patients’ voiding symptoms.

• Prostate Volume >40 mL. There is no upper limit on prostate size for PAE.

• Urodynamic studies with peak urinary flow rate (Qmax) <12 mL/s, which is predictive of bladder outlet obstruction.

The patient presented for PAE. Access to the right femoral artery was obtained.  An Omni flush catheter and Bentson wire were used to go over the iliac bifurcation, and a Roberts Uterine Catheter (RUC, now renamed RBT) was used to select the left internal iliac artery. DSA was performed. Which vessel is the left prostatic artery?
