Enlarged prostate or benign prostatic hyperplasia (BPH) is often considered a mild and tolerable condition, especially among older men. However, if left untreated, an enlarged prostate can lead to various serious complications that negatively affect health and quality of life. These complications range from urinary tract infections (UTIs), the presence of blood in the urine and bladder stone formation, to the risk of kidney damage. Therefore, complications of an enlarged prostate should be recognized early to prevent progression into more severe conditions.
Before the condition worsens, enlarged prostate should be treated as early as possible. Mandaya Royal Puri Hospital offers REZUM water vapor therapy, a non-surgical treatment for enlarged prostate that does not interfere with male sexual function, including ejaculation and erection.

Complications of Enlarged Prostate If Left Untreated
The prostate surrounds the urethra or urinary tract. When the prostate enlarges, it can compress and obstruct the urethra. If left untreated, BPH can cause increasingly severe blockage of the urethra, leading to worsening urinary symptoms.
Below are several complications and risks of enlarged prostate if not properly treated:
1. Urinary Tract Infection (UTI)
An enlarged prostate can compress the urethra and obstruct urine flow, preventing the bladder from emptying completely. This residual urine becomes an ideal environment for bacterial growth, increasing the risk of urinary tract infections (UTIs). Symptoms commonly include painful urination, frequent urination, and discomfort in the lower abdomen.
2. Bladder Stones
Obstructed urine flow caused by an enlarged prostate can result in urine being retained in the bladder for extended periods. Over time, mineral deposits in the urine may harden and form bladder stones. This condition can cause pain, difficulty urinating, and increase the risk of recurrent urinary tract infections.
3. Blood in the Urine (Hematuria)
An enlarged prostate may cause blood vessels around the prostate and bladder to become more fragile. Pressure from obstructed urine flow can irritate or rupture these blood vessels, resulting in blood in the urine. Hematuria caused by BPH may occur repeatedly and requires further medical evaluation.
4. Kidney Damage
If an enlarged prostate is left untreated, prolonged urinary obstruction may cause urine to flow backward from the bladder to the kidneys. This backflow increases pressure on the kidneys and, over time, can damage kidney tissue and impair kidney function. Early treatment of enlarged prostate is therefore crucial to prevent this serious complication.
REZUM Water Vapor Therapy for Treating Enlarged Prostate
REZUM is a minimally invasive therapy that uses heated water vapor to treat benign prostatic hyperplasia (BPH). This method works by targeting and gradually destroying excess prostate tissue, allowing the prostate to shrink without the need for surgery or incisions. REZUM therapy is known to preserve male sexual function, including erection and ejaculation, while offering faster recovery and effective relief of urinary symptoms.
The following are the stages of how REZUM water vapor therapy works to treat enlarged prostate without surgery:
- A specialized device is inserted through the urethra.
- Water vapor is delivered in a controlled manner to the enlarged prostate tissue.
- Thermal energy from the vapor destroys excess prostate cells that compress the urethra.
- The damaged prostate tissue is naturally absorbed by the body, allowing the prostate to shrink and urine flow to improve.
Advantages of REZUM Water Vapor Therapy
REZUM water vapor therapy offers several advantages as a non-surgical solution for enlarged prostate, including:
- Minimally invasive: No incisions required, with a relatively short procedure time of approximately 10–30 minutes.
- Fast recovery: Most patients can be treated on an outpatient basis and return to normal activities within a few days.
- Preserves sexual function: Does not interfere with erection or ejaculation.
- Effective: Provides long-lasting improvement of urinary symptoms.
- Low risk: Lower complication rates compared to conventional prostate surgery.
