Jackstone calculus is a type of urinary tract stone characterized by its unique appearance with stippled and spiculated contour, resembling a toy jack. [1] [2] Jackstone calculi are composed of calcium oxalate dihydrate, which gives them their irregular shape. [3] They are often detected in radiological investigations or cystoscopy. [4]
Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material develops in the urinary tract. Renal calculi typically form in the kidney and leave the body in the urine stream. A small calculus may pass without causing symptoms. If a stone grows to more than 5 millimeters, it can cause blockage of the ureter, resulting in sharp and severe pain in the lower back that often radiates downward to the groin. A calculus may also result in blood in the urine, vomiting, or painful urination. About half of people who have had a renal calculus are likely to have another within ten years.
A bladder stone is a stone found in the urinary bladder.
A varicocele is, in a man, an abnormal enlargement of the pampiniform venous plexus in the scrotum; in a woman, it is an abnormal painful swelling to the embryologically identical pampiniform venous plexus; it is more commonly called pelvic compression syndrome. In the male varicocele, this plexus of veins drains blood from the testicles back to the heart. The vessels originate in the abdomen and course down through the inguinal canal as part of the spermatic cord on their way to the testis. Varicoceles occur in around 15% to 20% of all men. The incidence of varicocele increase with age.
An antihemorrhagic agent is a substance that promotes hemostasis. It may also be known as a hemostatic agent.
Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones. The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract. Acute obstruction and the resultant urinary stasis can distend the ureter (hydroureter) and cause a reflexive peristaltic smooth muscle spasm, which leads to a very intense visceral pain transmitted via the ureteric plexus.
Nocturia is defined by the International Continence Society (ICS) as "the complaint that the individual has to wake at night one or more times for voiding ". The term is derived from Latin nox – "night", and Greek [τα] ούρα – "urine". Causes are varied and can be difficult to discern. Although not every patient needs treatment, most people seek treatment for severe nocturia, waking up to void more than 2 or 3 times per night.
Adenine phosphoribosyltransferase deficiency is a rare autosomal recessive metabolic disorder caused by mutations of the APRT gene. Adenine phosphoribosyltransferase (APRT) catalyzes the creation of pyrophosphate and adenosine monophosphate from 5-phosphoribosyl-1-pyrophosphate and adenine. Adenine phosphoribosyltransferase is a purine salvage enzyme. Genetic mutations of adenine phosphoribosyltransferase make large amounts of 2,8-Dihydroxyadenine causing urolithiasis and renal failure.
Neurogenic bladder dysfunction, often called by the shortened term neurogenic bladder, refers to urinary bladder problems due to disease or injury of the central nervous system or peripheral nerves involved in the control of urination. There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms. Symptoms include overactive bladder, urinary urgency, frequency, incontinence or difficulty passing urine. A range of diseases or conditions can cause neurogenic bladder including spinal cord injury, multiple sclerosis, stroke, brain injury, spina bifida, peripheral nerve damage, Parkinson's disease, multiple system atrophy or other neurodegenerative diseases. Neurogenic bladder can be diagnosed through a history and physical as well as imaging and more specialized testing. In addition to symptomatic treatment, treatment depends on the nature of the underlying disease and can be managed with behavioral changes, medications, surgeries, or other procedures. The symptoms of neurogenic bladder, especially incontinence, can severely degrade a person's quality of life.
Chronic bacterial prostatitis is a bacterial infection of the prostate gland. It should be distinguished from other forms of prostatitis such as acute bacterial prostatitis and chronic pelvic pain syndrome (CPPS).

Sarcoidosis is a systemic disease of unknown cause that results in the formation of non-caseating granulomas in multiple organs. The prevalence is higher among black males than white males by a ratio of 20:1. Usually the disease is localized to the chest, but urogenital involvement is found in 0.2% of clinically diagnosed cases and 5% of those diagnosed at necropsy. The kidney is the most frequently affected urogenital organ, followed in men by the epididymis. Testicular sarcoidosis can present as a diffuse painless scrotal mass or can mimic acute epididymo-orchitis. Usually it appears with systemic manifestations of the disease. Since it causes occlusion and fibrosis of the ductus epididymis, fertility may be affected. On ultrasound, the hypoechogenicity and ‘infiltrative’ pattern seen in the present case are recognized features. Opinions differ on the need for histological proof, with reports of limited biopsy and frozen section, radical orchiectomy in unilateral disease and unilateral orchiectomy in bilateral disease. The peak incidence of sarcoidosis and testicular neoplasia coincide at 20–40 years and this is why most patients end up having an orchiectomy. However, testicular tumours are much more common in white men, less than 3.5% of all testicular tumours being found in black men. These racial variations justify a more conservative approach in patients of Afro-Caribbean descent with proven sarcoidosis elsewhere. Careful follow-up and ultrasonic surveillance may be preferable in certain clinical settings to biopsy and surgery, especially in patients with bilateral testicular disease.
Ascher's syndrome is a rare clinical entity distinguished by blepharochalasis, double upper lip appearance, and nontoxic goiter. Nontoxic goiter is a rare finding, occurring in only 10-50% of cases. It may appear several years following the onset of blepharochalasis, so it is not considered necessary for the diagnosis of Ascher's syndrome. The condition was initially identified by Ascher, an ophthalmologist from Prague, in 1920. The cause of this syndrome is still unknown, though trauma and hormonal dysfunction have been suggested as possible causes.

Eosinophilic cystitis is a rare type of interstitial cystitis first reported in 1960 by Edwin Brown. Eosinophilic cystitis has been linked to a number of etiological factors, including allergies, bladder tumors, trauma to the bladder, parasitic infections, and chemotherapy drugs, though the exact cause of the condition is still unknown. The antigen-antibody response is most likely the cause of eosinophilic cystitis. This results in the generation of different immunoglobulins, which activate eosinophils and start the inflammatory process.
An artificial urinary sphincter (AUS) is an implanted device to treat moderate to severe stress urinary incontinence, most commonly in men. The AUS is designed to supplement the function of the natural urinary sphincter that restricts urine flow out of the bladder.

Vesicouterine fistula refers to an abnormal communication between the bladder and uterus. The first case of vesicouterine fistula was reported in 1908. It was however first described in 1957 by Abdel Fattah Youssef, an obstetrician and gynaecologist in Kasr el-Aini hospital, Cairo, Egypt. It is characterized by a vesicouterine fistula above the level of the internal os, absence of menstrual bleeding, cyclical presence of blood in urine and absence of urinary incontinence with a patent cervical canal following a lower segment caesarean section. Six of such cases had been reported by other clinicians before the term Menouria was coined by Youssef.
