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 ( ), upper urinary tract dilation ( ), compromised renal function ( ), urinary tract infection ( ), neurological diagnosis ( ), or preferred immediate channel transurethral resection of prostate ( ), 48 of 69 consecutive patients ≥70 years were included. Mean age was 76.6 years (70–84), mean prostate volume 90 cm3 (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 ). 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.
