Enlarged prostate, or benign prostatic hyperplasia (BPH), is a condition where the prostate gland increases in size as men age. This can cause symptoms such as frequent urination, weak urine flow, difficulty starting urination, and a feeling of incomplete bladder emptying. Normally, the prostate size in adult men ranges from around 20–30 cc. However, in some cases, it can grow much larger, such as a patient at Mandaya Royal Puri Hospital whose prostate reached 65 cc, leading to more significant symptoms.
To address this condition, dr. Maruto Harjanggi, BSc(Hons), Sp.U, FICS, a urology specialist at Mandaya Royal Puri Hospital, is experienced in performing the Rezum procedure. This method is a minimally invasive therapy used to reduce prostate size without major surgery and is designed to preserve male sexual function, including erection and ejaculation.

What is Rezum for enlarged prostate?
Rezum is a treatment method for BPH that uses heated water vapor (steam) to shrink enlarged prostate tissue. This procedure is considered minimally invasive because it does not require major surgery and is performed through the urinary tract without any incisions. Its goal is to relieve pressure on the urethra so that urination becomes smoother.
Here is a simple overview of the Rezum procedure:
- Patient preparation: The patient is given local or mild anesthesia to ensure comfort during the procedure.
- Device insertion through the urinary tract: A small specialized instrument is inserted through the urethra to reach the prostate without any incision.
- Steam delivery: Heated water vapor is directed into the enlarged prostate tissue to destroy excess tissue.
- Gradual shrinkage of prostate tissue: The treated tissue is naturally absorbed by the body over weeks to months, reducing prostate size.
- Improved urine flow: As the prostate shrinks, pressure on the urinary tract decreases, improving symptoms.
This procedure is generally quick, causes minimal discomfort, and has a lower risk compared to conventional surgery, while preserving sexual function.
Patient condition explained by dr. Maruto
“Today we are performing another Rezum procedure. This patient has a relatively large prostate, measuring 65 cc,” said dr. Maruto.
During the procedure, the patient remains awake and can even see the prostate condition on the monitor while dr. Maruto performs the treatment.
At the same time, dr. Maruto explains the condition, noting that even fluid has difficulty passing through the prostate due to its enlarged size. The patient is also able to respond and interact during the explanation.
When the Rezum device is inserted through the urinary tract, dr. Maruto explains each step, including when the steam is delivered. The entire procedure takes only about 15 minutes, ensuring patient comfort.
