Modern urology increasingly favors minimally invasive solutions. Prostatic artery embolization (PAE) has emerged as an attractive alternative to traditional surgical interventions for benign prostatic hyperplasia (BPH), offering symptom relief without tissue resection and with a lower risk of sexual dysfunction….
Pulmonary arterial hypertension (PAH) has long been described in textbooks as a rare disease of younger patients, often women, with few comorbidities and a clean cardiovascular background. That image is now largely obsolete. Contemporary registries and everyday clinical practice tell…
Erectile dysfunction (ED) is often treated as a local mechanical problem with a systemic medication. That sentence sounds contradictory, but it’s an accurate summary of modern practice. We prescribe phosphodiesterase type 5 inhibitors (PDE5 inhibitors) to improve penile blood flow,…
Lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) are two conditions that like to arrive as a pair—especially as men age. Many patients come in talking about urinary frequency, nocturia, weak stream, or…
Phosphodiesterase type 5 (PDE5) inhibitors—sildenafil, tadalafil, vardenafil, and avanafil—changed erectile dysfunction (ED) care more than any marketing campaign could ever claim. They offered a reliable oral option, moved ED treatment out of the “awkward procedures” category, and gave patients back…
Neurodegeneration is often introduced with a gloomy statistic—and for once, the gloom is justified. Dementia affects tens of millions of people worldwide and is expected to rise dramatically as populations age. In parallel, the therapeutic toolbox for Alzheimer’s disease (AD)…
Erectile function (EF) recovery after bilateral nerve-sparing radical prostatectomy (nsRP) is one of the most emotionally charged “numbers” in modern urology. Not because clinicians enjoy questionnaires, but because patients do. A man can accept a scar, tolerate transient fatigue, and…
Heart failure rarely begins with drama. It begins quietly—an ejection fraction that slips below normal, a ventricle that remodels, a left atrium that enlarges—while the patient still insists they feel “fine.” This stage, commonly called preclinical systolic dysfunction (PSD) and…
Erectile dysfunction (ED) drugs are often discussed in the language of convenience: “quick onset,” “long duration,” “works when you need it.” That framing is practical, but biologically incomplete. Phosphodiesterase type 5 (PDE5) inhibitors do not operate only in the penis;…
Radical prostatectomy remains one of the most effective curative options for localized prostate cancer. The surgery is technically elegant, oncologically meaningful, and—if you ask most patients—life-saving. Then the postoperative reality arrives with less elegance: erectile dysfunction (ED) and urinary incontinence…
Erectile dysfunction (ED) is often described in textbooks with neat definitions, but in real clinics it behaves like a chronic condition with mood swings. A patient may do “fine” for months, then relapse after stress, vascular progression, or simply aging…
