Cystitis (sis-TIE-tis) is the medical term for inflammation of the bladder. Most of the time, the inflammation is caused by a bacterial infection, and it's called a urinary tract infection (UTI). A bladder infection can be painful and annoying, and it can become a serious health problem if the infection spreads to your kidneys. Less commonly, cystitis may occur as a reaction to certain drugs, radiation therapy or potential irritants, such as feminine hygiene spray, spermicidal jellies or long-term use of a catheter. Cystitis may also occur as a complication of another illness. The usual treatment for bacterial cystitis is antibiotics. Treatment for other types of cystitis depends on the underlying cause

Kidney stones (also called renal calculi, nephrolithiasis or urolithiasis) are hard deposits made of minerals and salts that form inside your kidneys. Diet, excess body weight, some medical conditions, and certain supplements and medications are among the many causes of kidney stones. Kidney stones can affect any part of your urinary tract — from your kidneys to your bladder. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. Passing kidney stones can be quite painful, but the stones usually cause no permanent damage if they're recognized in a timely fashion. Depending on your situation, you may need nothing more than to take pain medication and drink lots of water to pass a kidney stone. In other instances — for example, if stones become lodged in the urinary tract, are associated with a urinary infection or cause complications — surgery may be needed. Your doctor may recommend preventive treatment to reduce your risk of recurrent kidney stones if you're at increased risk of developing them again.

Circumcision is the surgical removal of the skin covering the tip of the penis. The procedure is fairly common for newborn boys in certain parts of the world, including the United States. Circumcision after the newborn period is possible, but it's a more complex procedure. For some families, circumcision is a religious ritual. The procedure can also be a matter of family tradition, personal hygiene or preventive health care. For others, however, circumcision seems unnecessary or disfiguring.

Prostate cancer is cancer that occurs in the prostate. The prostate is a small walnut-shaped gland in males that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is one of the most common types of cancer. Many prostate cancers grow slowly and are confined to the prostate gland, where they may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly. Prostate cancer that's detected early — when it's still confined to the prostate gland — has the best chance for successful treatment.

Transurethral resection of the prostate (TURP) is a surgery used to treat urinary problems that are caused by an enlarged prostate. An instrument called a resectoscope is inserted through the tip of your penis and into the tube that carries urine from your bladder (urethra). The resectoscope helps your doctor see and trim away excess prostate tissue that's blocking urine flow. TURP is generally considered an option for men who have moderate to severe urinary problems that haven't responded to medication. While TURP has been considered the most effective treatment for an enlarged prostate, a number of other, minimally invasive procedures are becoming more effective. These procedures generally cause fewer complications and have a quicker recovery period than TURP

Double-J ureteral stents are commonly used to manage urinary obstructions. Pain, bladder irritative symptoms, and fever are usually signs of early complications related to double-J stents; late complications are more troublesome. We review 4 cases that highlight a variety of late complications with double-J stents (encrustation, migration, and fragmentation). Following a review of the literature, guidelines are established for monitoring potential risk factors as well as management strategies for prevention of possible complications when using double-J stents.

Benign prostatic hyperplasia (BPH) — also called prostate gland enlargement — is a common condition as men get older. An enlarged prostate gland can cause uncomfortable urinary symptoms, such as blocking the flow of urine out of the bladder. It can also cause bladder, urinary tract or kidney problems. There are several effective treatments for prostate gland enlargement, including medications, minimally invasive therapies and surgery. To choose the best option, you and your doctor will consider your symptoms, the size of your prostate, other health conditions you might have and your preferences.
