Prostate cancer is the second most common cancer in the world, with an estimated 1 million births a year, and a death toll of about 40000. The risk of prostate cancer in men is 1, 6. Prostate cancer detection rates vary widely in different countries. Since the introduction of the serum PSA (prostate specific antigen) test, after 90s, the portion of low-risk cancers has risen dramatically in the world. After the initial peak, the incidence decreased, but in the pre-PSA era, their ratios lasted nearly twice times. Many screenings have found that the risk of prostate cancer is low, with little impact on life expectancy. The most important risk factors for prostate cancer are age, race, genetic factors, and diet. However, the screening of prostate cancer has caused some controversy.
A fairly common but relatively asymptomatic form of cancer. It has been shown that weight-gain patients and genetics may increase the risk of kidney cancer. Management relies on early detection. There is a genetic and dietary component to the pathogenesis of renal carcinoma. Renal cell carcinoma or clear cell carcinoma accounts for about 80% of the renal tumor. The rest of the tumors are benign, pelvic and renal sarcoma.
Bladder cancer is the most common malignancy, involving the urinary system and the nineth most common malignancy in the world. The cutaneous gland (formerly known as transitional Cell) carcinoma accounted for 90% of bladder cancer, while the remainder was adenocarcinoma and small cell carcinoma. Smoking is the most important risk factor for adenocarcinoma of the skin. Other factors, such as industrial dyes and genetic factors, may also play a part in their pathogenesis.
Many factors can lead to erectile dysfunction. The most important factors affecting sexual activity are age, general health and psychological problems. Men usually maintain sexual impulses and remain sexually active for longer periods of time, but they may experience premature ejaculation, delayed erection, reduced hardness and duration of orgasm.
Management of urethral and ureteral lesions (puj obstruction) and the formation of ileal ureter and artificial bladder.
