How quickly does androgen deprivation therapy relieve difficulty passing urine?

Androgen deprivation therapy lowers the effect of hormones that can stimulate prostate-cancer growth. If cancer-related prostate or tumour tissue is contributing to pressure around the urethra, urinary flow may improve as that tissue responds. The response is not immediate for everyone.

Difficulty passing urine can also result from prostate enlargement, infection, medicines, scar tissue, or a clot. ADT may not address those causes. A clinician may need to check the bladder and kidneys and decide whether a catheter, medicine, procedure, or another cancer treatment is needed.

Take ADT exactly as prescribed and report worsening flow, pain, fever, blood in urine, or increasing lower-abdominal pressure. Do not delay contact with the oncology or urology team because the treatment has only recently started.

Keep track of how often you pass urine, whether the stream changes, and whether the bladder feels empty. These details help the team judge response and choose added support.

Seek urgent medical care if you cannot pass urine, have severe lower-abdominal pain or swelling, develop fever with urinary symptoms, or become confused or very weak. Complete blockage can require immediate drainage.

What is causing my difficulty passing urine? When should improvement be expected in my situation? What symptoms mean I need urgent drainage? Could another medicine or procedure provide relief while ADT takes effect?
