Water vapour therapy is a day-case treatment for an enlarged prostate, taking under ten minutes. This page covers what happens afterwards — the part that determines how the next few weeks feel.

For the procedure itself see what it does and what to expect и how the vapour shrinks the prostate, and for the condition it treats, benign prostatic enlargement.

Когда нужно обратиться за помощью, а не ждать

This section was missing from the earlier version of this page and belongs before the routine instructions. You will be at home with a catheter, and some of these cannot wait for the next clinic appointment. Вернитесь в больницу в тот же день при любом из следующих симптомов. В экстренной ситуации в Таиланде звоните по номеру 1669.

Свяжитесь с больницей, а не через личные каналы или мессенджеры: Bangkok Hospital Headquarters, или Госпиталь Samitivej Sriracha по номеру 088-022-1445. Outside working hours, go to the emergency department.

Blood in the semen deserves a note of its own, because it alarms men who were not warned: it is expected, it can look dramatic, and it may persist for several weeks. It is not a sign that anything has gone wrong.

Часто задаваемые вопросы

How long do I need the catheter?

Most men need a urethral catheter for 1–2 weeks, and the duration depends on prostate size — a larger prostate may need longer. Your urologist will arrange the removal appointment and check that you can pass urine before you go home.

When will my symptoms improve?

Some improvement usually starts around 2 weeks as the initial swelling settles, with the best result at about 3 months once the treated tissue has been reabsorbed. Irritative symptoms in the early weeks are part of that course rather than a setback.

What side effects should I expect?

Commonly painful urination, blood in the urine, urinary retention, urgency and frequency, blood in the semen, urinary infection and pelvic pain — most settling within about three weeks. Blood in the semen can last several weeks and is not a complication.

Can I go home the same day?

Usually yes. After 1–2 hours of observation most men are discharged the same day, with the catheter in place and after a nurse has shown you how to manage the bag. Overnight admission is sometimes recommended.

Do I still need my prostate medication?

Yes, for the first 30 days, to manage symptoms during the transitional healing period. As the treated tissue is reabsorbed and symptoms improve, your urologist will reassess whether it is still needed.

My catheter has stopped draining. What do I do?

Go to the hospital the same day, particularly if your lower abdomen feels full and uncomfortable. A blocked catheter is not something to wait out, and it should not be flushed or replaced at home. The same applies if the catheter falls out before its removal date.
