Urinary Retention following Prostate Seed Implant Brachytherapy following Rigid Cystoscopy

Abstract

Purpose/Objective(s): Transperineal ultrasound guided prostate seed brachytherapy (PSI) is a common procedure performed for the long-term control of prostate cancer. After the completion of the procedure, a cystoscopy is often performed to ensure that no seeds were inadvertently introduced into the bladder. After the patient recovers, he is generally given a trial of voiding. If the patient cannot urinate or has significant urinary retention, a Foley catheter is generally replaced, and the patient is sent home with the catheter for 1-2 weeks to allow for a decrease in prostatic edema. Published studies have shown differences in urinary symptoms for patients who underwent rigid versus flexible cystoscopy outside of the setting of PSI. Here, we investigate possible factors including cystoscopy that may contribute to urinary toxicity, the most common form of toxicity in patients receiving PSI.
