title: Diethylstilbestrol 1 mg in the Treatment of Acute Urinary Retention due to Prostatic Obstruction in the Elderly: A Preliminary Study.
abstract: Patients who failed a catheter-free trial after acute urinary retention and one week of full dose alpha-blocker and 5-alpha-reductase inhibitor were offered Diethylstilbestrol 1 mg plus Aspirin 100 mg over 4 weeks. Prostate volume, age, serum creatinine, and initial retention drained urine volume were recorded. After excluding cardiovascular morbidity (n = 7), upper urinary tract dilation (n = 3), compromised renal function (n = 2), urinary tract infection (n = 2), neurological diagnosis (n = 2), or preferred immediate channel transurethral resection of prostate (n = 5), 48 of 69 consecutive patients ≥70 years were included. Mean age was 76.6 years (70-84), mean prostate volume 90 cm(3) (42-128), and mean follow-up 204 days; 58% (28/48) were passing urine and 42% (20/48) were catheter dependent after 4 weeks Diethylstilbestrol trial. Mean age and drained urine volume of catheter dependent patients were 82.4 years and 850 mL compared with 74.6 years and 530 mL in catheter-free men, respectively. Age and drained urine volume were independent predictors of catheter-free trial (both P < 0.01). Seventy-five percent (6/8) of patients 80 years and older were catheter dependent. Transient nipple/breast tenderness and gynecomastia were the only adverse effects reported by 21% (10/48) and 4% (2/48), respectively. No patient presented severe complications.
