Here are answers to some common questions about proactive Urologic care with Dr. Sylvester Onyishi:

What is a Urologist?

Dr. Onyishi and our team of urologists are surgical specialists who diagnose and treat conditions of the urinary tract in both men and women, and the male reproductive system. We manage a wide range of issues, from kidney stones and urinary tract infections to cancers of the prostate, bladder, and kidneys.

At what age should men start discussing prostate cancer screening?

Discussions about prostate cancer screening, including the PSA blood test, typically begin around age 50 for average-risk men. However, for higher-risk men, such as African American men or those with a family history, this discussion should ideally start earlier, around age 40-45. This decision is best made in a shared discussion with Dr. Onyishi.

What are the signs of a urinary tract infection (UTI)?

Common UTI symptoms include frequent or urgent urination, burning during urination, cloudy or strong-smelling urine, and pelvic pain. See Dr. Onyishi for diagnosis and treatment to prevent potential kidney infection.

I am a woman experiencing urinary leakage. Should I see a Urologist?

Yes, a urologist can help. Urologists are experts in both the male and female urinary tract. Dr. Onyishi specializes in diagnosing and treating all types of female urinary incontinence, offering solutions ranging from pelvic floor therapy to minimally invasive procedures.

What is robotic surgery, and what are its benefits?

Robotic surgery, like the da Vinci® system, is a minimally invasive technique where a surgeon uses a console to control robotic arms with tiny instruments. This leads to smaller incisions, less pain, reduced blood loss, and a faster recovery compared to traditional open surgery.

I have been diagnosed with a kidney stone. Will I need surgery?

Most small kidney stones pass naturally with increased fluid intake and pain management. For larger stones or those causing significant issues, Dr. Onyishi can use minimally invasive procedures like shock wave lithotripsy or ureteroscopy to effectively break up or remove the stone.

What is an 'overactive bladder' (OAB)?

Overactive bladder (OAB) is a condition characterized by a sudden, frequent, and urgent need to urinate, which can be difficult to control and may lead to leakage. It's a common condition, and Dr. Onyishi can offer many effective treatments, including behavioral strategies, medications, and advanced therapies.

What is a vasectomy?

A vasectomy is a safe, simple, and highly effective form of permanent male contraception. It's a minor surgical procedure, often done in the office, that blocks the tubes carrying sperm. Importantly, it does not affect testosterone levels or sexual function.
