Tap any condition for a brief explanation.

  • Prostate cancer

    Cancer that develops in the prostate gland — one of the most common cancers in men, often found through PSA screening or a physical exam. Treatment options range from active surveillance to robotic prostatectomy, with a nerve-sparing technique used when possible to help preserve erectile function and continence.

  • Kidney cancer

    Cancer that begins in the kidney, often found incidentally on imaging done for another reason. Depending on the tumor's size and location, treatment may involve a nephron-sparing partial nephrectomy to preserve healthy kidney tissue, or removal of the entire kidney.

  • Bladder cancer

    Cancer that develops in the lining of the bladder, most often first noticed as blood in the urine. Evaluation typically includes cystoscopy, and treatment ranges from tumor resection (TURBT) to robotic removal of the bladder for more advanced disease.

  • Testicular cancer

    Cancer that develops in the testicle, most common in younger and middle-aged men. Often first noticed as a painless lump or swelling, and highly treatable when caught early.

  • Enlarged prostate (BPH)

    Non-cancerous enlargement of the prostate that can cause urinary blockage and bothersome symptoms such as a weak stream, frequent urination, or waking at night to urinate. Treatment ranges from medication to office-based procedures like UroLift and Rezum, or surgery for larger prostates.

  • Kidney stones

    Hard mineral deposits that form in the kidney and can cause severe pain, blood in the urine, or blockage as they pass. Larger or more complex stones may require ureteroscopy, laser lithotripsy, or PCNL to remove.

  • Voiding dysfunction

    Difficulty emptying the bladder normally — a weak stream, hesitancy, straining, or a sense of incomplete emptying — which can stem from a range of underlying causes.

  • Erectile dysfunction

    Difficulty achieving or maintaining an erection sufficient for sexual activity. Often related to vascular, hormonal, or nerve-related factors, with treatment options ranging from medication to other therapies.

  • Hydrocele

    A fluid-filled sac that forms around the testicle, causing scrotal swelling. Usually painless, but can be surgically corrected if large or bothersome.

  • Incontinence

    Involuntary leakage of urine, ranging from occasional leaks with coughing or exercise to a complete loss of bladder control. Evaluation guides treatment, from pelvic floor therapy to surgical options.

  • Urinary tract infections (UTIs)

    Bacterial infections of the urinary tract, causing burning, urgency, and frequency. Recurrent UTIs may warrant further evaluation to identify an underlying cause.

  • Infertility

    Difficulty conceiving, evaluated and treated from a male reproductive health standpoint, including hormonal, anatomic, and lifestyle factors that can affect fertility.

  • Hematuria

    Blood in the urine — visible to the eye or found only on lab testing — that always warrants evaluation to rule out stones, infection, or a tumor as the underlying cause.

  • Testosterone deficiency

    Low testosterone levels that can cause fatigue, reduced libido, low mood, or loss of muscle mass. Diagnosed with blood testing and managed with individualized treatment.

  • Urinary tract obstruction

    A blockage anywhere along the urinary tract — from the kidney to the bladder — that prevents normal urine flow and, if untreated, can affect kidney function.

  • Urinary tract reconstruction

    Surgical repair or rebuilding of the urinary tract to restore normal anatomy and function, often needed after prior surgery, injury, or a congenital abnormality.

  • Vasectomy

    A minor procedure providing permanent contraception, offered as part of general urologic care and typically performed in the office under local anesthesia.

  • Overactive bladder

    Sudden, frequent urges to urinate, often with urgency and occasional leakage. Treatment can range from behavioral changes and medication to more advanced therapies for persistent symptoms.

  • Urethral stricture

    Narrowing of the urethra — often from prior injury, infection, or surgery — that can slow or block the normal flow of urine and may require dilation or surgical repair.

  • Varicocele

    Enlarged veins within the scrotum, similar to varicose veins, which can affect fertility, testicular size, or cause a dull ache or heaviness.

  • Sexual health

    Evaluation and treatment of sexual health concerns, including low libido, ejaculatory issues, and other men's sexual wellness needs, addressed with an individualized approach.
