Acute urinary retention (AUR) is a common complication of a neoplastic prostate. Prostate cancer is one of the most common epithelial tumors in older men. Palliative TURP (“channel” TURP),is transurethral resection of prostate tissue in a patient with metastatic or locally advanced and/or previously treated prostate cancer to alleviate obstructive voiding symptoms (e.g. AUR). The estimated incidence of urinary retention in patients with advanced prostate cancer is nearly 13.0% . We report a case of 77 year old patient presenting with acute urinary retention to our emergency department and was further diagnosed with adenocarcinoma of prostate with a Gleason score of (5+4=9). We present this case to highlight the efficacy of Bilateral Orchiectomy and Channel TURP in relieving urinary retention in patients with advanced prostate cancer presenting with urinary retention or a high post-void residual urine volume (PVR).
