Background Pain at ejaculation/orgasm perceived in perineum, urethra and/or urethral meatus, has a profound impact on the quality of life of the affected man. Although underestimated, this condition is reported to have a 1–9.7% prevalence over the general population. Methods Structured review of the relevant available literature. Results Among the main causes of pain experienced at ejaculation/orgasm are: prostatevesicular causes (LUTS/BPH, prostatitis, ejaculatory duct obstruction, vesicular stone), postsurgical causes (radical prostatectomy, inguinal hernioplasty), pharmacologic causes (antidepressants), psychogenic causes (psychosexual conflicts, sexual abuse), rare causes. For these pathologies, diagnostic and therapeutic strategies have been proposed. Conclusions Ejaculatory pain is associated with a high level of personal distress, and represents a possible request for help within the andrologic/urologic area. Each field specialist should be competent in correctly interpreting every single case, in order to manage it appropriately.

Other potential benefits include: * Surgical retreatment rate: after 5 years, only 4.4% of patients needed another surgery for BPH symptoms * Does not typically require general anesthesia * No permanent implant * Preserves sexual function * Symptom relief that lasts However, potential risks include and are not limited to: * Painful or frequent urination * Blood in the urine or semen * Decrease in ejaculatory volume * Urinary tract infection (UTI) * Inability to urinate or completely empty the bladder * Urgent need to urinate * Inability to ejaculate * Urinary incontinence * Inflammation of the epididymis * Worsening erectile dysfunction * Pain/discomfort with ejaculation * Pelvic or penile pain/discomfort * Poor or splayed urine stream * Inflammation of the prostate gland * Scarring and narrowing of the urethra In rare occasion, the following AEs may occur including narrowing of the bladder neck, bladder stone, and severe infection. In addition, patient may experience continued of worsening BPH symptoms during healing phase.

crystallize as kidney stones. They grow and can become painful irritants that may require surgery or ultrasound treatments. Some stones are small enough The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state Maintain volume of extracellular fluid Maintain ionic balance in extracellular fluid Maintain pH and osmotic concentration of the extracellular fluid. Excrete toxic metabolic by-products such as urea, ammonia, and uric acid. The way the kidneys do this is with nephrons. There are over 1 million nephrons in each kidney; these nephrons act as filters inside the kidneys. The kidneys filter needed materials and waste. Needed materials go back into the bloodstream; unneeded materials become urine and are expelled through the urethra. In some cases, excess wastes crystallize as kidney stones. They grow and can become painful irritants that may require surgery or ultrasound treatments. Some stones are small enough to be forced into the urethra. Scient… The kidneys are large, bean-shaped organs which are present on each side of the vertebral column in the abdominal cavity. Humans have two kidneys that are supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The renal vein (or kidney vein) carries the filtrated blood away from the kidneys. Urine passes from the kidneys though the ureters to the urinary bladder and passes through the urethra during urination. The kidney's primary function is the elimination of waste from the bloodstream by production of urine. They perform several homeostatic functions such as:- Maintain volume of extracellular fluid Maintain ionic balance in extracellular fluid Maintain pH and osmotic concentration of the extracellular fluid. Excrete toxic metabolic by-products such as urea, ammonia, and uric acid. The way the kidneys do this is with nephrons.

The ureters are muscular ducts that propel urine from the kidneys to the urinary bladder. In the human adult, the ureters are usually 25–30 cm (10–12 in) long. In humans, the ureters arise from the renal pelvis on the medial aspect of each kidney before descending towards the bladder on the front of the psoas major muscle. The ureters cross the pelvic brim near the bifurcation of the iliac arteries (which they run over). This "pelviureteric junction" is a common site for the impaction of kidney stones (the other being the ureterovesical valve). The ureters run posteriorly on the lateral walls of the pelvis. They then curve anterior medially to enter the bladder through the back, at the vesicoureteric junction, running within the wall of the bladder for a few centimeters. The backflow of urine is prevented by valves known as ureterovesical valves. In the female, the ureters pass to the bladder through the mesometrium. The liver detoxifies and breaks down chemicals, poisons and other toxins that enter the body. For example, the liver transforms ammonia (which is poisonous) Within the kidney, blood first passes through the afferent artery to the capillary formation called a glomerulus and is collected in the Bowman's capsule, which filters the blood from its contents—primarily food and wastes. After the filtration process, the blood then returns to collect the food nutrients it needs, while the wastes pass into the collecting duct, to the renal pelvis, and to the ureter and are then secreted out of the body via the urinary bladder. Scientifically, masses referred to as a renal calculus or nephrolith, or more commonly, "kidney stones", are solid masses of crystals that may be a variety of shapes, sizes, and textures, that can reside within one or both of the kidneys. Kidney stones form when the balance is off between the concentration of substances that pass through urine, and the substances that are supposed to dissolve them. When substances are not properly dissolved, they have the ability to build up, and form these kidney stones. These stones are most commonly made up of substances such as calcium, cystine, oxalate, and uric acid, as these are the substances that normally would dissolve within the urine. When they do not dissolve correctly and further build up, they will commonly lodge themselves in the urinary tract and in this case, are usually small enough to pass through urine. In extreme situations, however, these stones may lodge themselves within the tube that connects the kidney and the bladder, called the ureter. In this case, they become very large in size and will most likely cause great pain, bleeding, and possibly even block the flow of urine. These can occur in both men and women, and studies show that around 12% of men, and 8% of women in America will develop kidney stones within their lifetime. Pyelonephritis is a type of urinary tract infection that occurs when bacteria enters the body through the urinary tract. It causes an inflammation of the renal parenchyma, calyces, and pelvis. There are three main classifications of pyelonephritis: acute, chronic and xanthogranulomatous.
