Final answer:
The most appropriate management for urinary incontinence with a postvoid residual urine volume of 30 ml in a 67-year-old male is to address the underlying enlarged prostate gland, likely caused by benign prostatic hyperplasia (BPH).
Step-by-step explanation:
The most appropriate management for a 67-year-old male with urinary incontinence and a postvoid residual urine volume of 30 ml is to address the underlying cause, which is likely an enlarged prostate gland (benign prostatic hyperplasia - BPH).
Medication is often the initial treatment for mild to moderate symptoms of BPH, and Tamsulosin, which the patient is already taking, is commonly prescribed to relax the muscles of the prostate and the bladder neck, improving urine flow.
However, since the patient is experiencing urinary incontinence, further evaluation and a urology referral may be necessary to determine if other interventions, such as surgery, are needed to relieve the pressure on the urethra and improve urinary continence.
