Sonography of fetal micturition. (1/14)

OBJECTIVE: To describe the sonographic visualization of fetal micturition and its role in the diagnosis of posterior urethral valves and hypospadias. METHODS: This was a prospective study of 25 male fetuses (21 with bilateral pyelectasis, one whose bladder was being studied because of ureterocele and three with hypospadias), and five female fetuses (with bilateral pyelectasis). A midline sagittal scan of the fetal pelvis, perineum and external genitalia was obtained and observed continuously during fetal micturition. RESULTS: In 19 of the 21 male fetuses and the five female fetuses with bilateral pyelectasis micturition was normal, with visualization of urinary bladder contraction, slight fluid distention of the urethra and a urinary stream from the external urethral meatus. In three male fetuses, two with bilateral pyelectasis and the one with ureterocele, the posterior urethra was normal at rest and it ballooned out during micturition, diagnostic of posterior urethral valves. In the three male fetuses with hypospadias the ventral jet of the urinary stream was visualized. CONCLUSION: Fetal micturition can be visualized on sonography. It may be of value in the diagnosis of posterior urethral valves and hypospadias.  (+info)

Simplified upper pole nephrectomy: initial experience. (2/14)

OBJECTIVE: To assess the results of an upper pole nephrectomy technique on 5 children. MATERIALS AND METHODS: Upper pole nephrectomy was performed on 5 children, including 4 females and 1 male. Age ranged from 3 to 6 years old. The technique was performed without initial dissection of the renal pedicle. The upper pole is incised and removed. Upon its complete dissection, the segment that drains the upper pole is easily identified, clamped and sectioned. RESULTS: Three children with ureterocele and 2 with ectopic ureter underwent this procedure. There was no intra- or postoperative complication with this technique. DSMA scintigraphy showed no decrease in renal function in the remaining kidney following the procedure. CONCLUSION: The polar nephrectomy technique is simple, and has the advantage of not approaching the renal hilum, which makes surgery less laborious and prevents risk of renal damage, hemorrhage and decreased function in the remaining renal portion.  (+info)

Familial ureteroceles: an evidence for genetic background? (3/14)

In the pediatric population, ureteroceles may present with different clinical pictures, and the severity of the renal damage is greater than in adults. Ureterocele, an anomaly of ureteric budding, is likely a component of a spectrum of anomalies including vesicoureteral reflux and ureteral duplications. Both have been confirmed to have a genetic and familial basis. We document the largest series of familial cases of ureteroceles, giving evidence for genetic background. We retrospectively reviewed the charts of patients with familial ureteroceles seen between 1992 and 2002. Coexisting ureteral anomalies and features of the cases were documented and compared to sporadic cases and all familial cases within the literature. This is the largest series of familial ureterocele patients in the literature. The review of the literature revealed seven publications with seven ureterocele families (15 affected patients) between 1936 and 2002. Comparing sex, ureterocele location, and single versus duplex systems, familial series are similar to other sporadic cases. Three of the families have twin siblings with ureteroceles. Familial cases, despite their rarity, raise the issue of the genetic origin of uretereoceles. Family members of ureterocele cases should be informed and followed carefully, especially twins. Increased reporting and genetic analysis of familial ureteroceles may prove to link the genetic mouse models of abnormal ureteric budding to the human conditions.  (+info)

Orthotopic ureterocele masquerading as a bladder tumor in a woman with pelvic pain. (4/14)

Single system orthotopic ureteroceles often present in adulthood are associated with characteristic radiographic findings. We present the case of a 54 year old woman with 8 months of urgency/frequency and pelvic pain that has the cystoscopic appearance of a bladder tumor. Cystoscopic images, radiographs and intraoperative photos demonstrate the work-up, evaluation, and treatment of this unique single system orthotopic ureterocele containing a calculus. This patient demonstrates the need for cystoscopy accompanied by upper tract imaging in patients with new onset pelvic pain, urgency/frequency, and frequent urinary tract infections.  (+info)

Prolapsing ectopic ureterocele presenting as a vulval mass in a newborn girl. (5/14)

Prolapse of the ureterocele and its presentation as a vulval mass is an extremely rare condition. There are no detailed imaging findings of such cases in the literature. We present voiding cystourethrography and MRI findings of a newborn girl with a ureterocele extending through the urethra.  (+info)

Postnatal evaluation of infants with an abnormal antenatal renal sonogram. (6/14)

PURPOSE OF REVIEW: Antenatally detected renal abnormalities are frequently encountered. Recommended postnatal evaluation of these infants has evolved to minimize invasive testing while maximizing detection of significant abnormalities. RECENT FINDINGS: There is a low rate of detectable renal abnormalities in infants with a normal postnatal sonogram at 4-6 weeks of age. Routine prophylactic antibiotics are not indicated in infants with isolated antenatal hydronephrosis. Infants with a multicystic dysplastic kidney and a normal contralateral kidney on renal ultrasound do not require further evaluation. Parents of these children should be counseled on symptoms of urinary tract infections to allow prompt diagnosis. SUMMARY: All infants with abnormalities on antenatal sonogram should undergo postnatal evaluation with a sonogram after birth and at 4-6 weeks of age. Further evaluation can be safely limited when the postnatal sonogram is normal at 6 weeks of age.  (+info)

The safety and efficacy of endoscopic incision of orthotopic ureterocele in adult. (7/14)

Endoscopic incision is a good management option for orthotopic ureterocele. But most of the literature has shown its efficacy only in children. We have done this retrospective study to evaluate the safety and efficacy of endoscopic incision of orthotopic ureterocele in adults. From March 2004 to January 2008, at our center, 26 adults underwent transurethral, transverse incision of an ureterocele. The perioperative data of these patients were retrospectively analyzed. The literature was reviewed to identify all the reported options for management of this relatively rare condition in adults. Unilateral ureterocele was present in 24 patients and two patients had bilateral ureterocele. One patient had associated upper tract stones. Three patients had associated stones in ureterocele. Transurethral, transverse incision of ureterocele was given in all patients. The mean postoperative hospital stay was 50.5 h. Twenty-three patients were available for follow-up at three, six and 12 months. All patients were symptom free. At three months ultrasound and intravenous urography revealed no residual ureterocele but four patients showed residual hydronephrosis, but with a decrease in the grade indicating decompression. Micturating cystourethrography revealed vesico-ureteral reflux (VUR) in two patients and the reflux persisted in one patient even at 6 months. We conclude that in adults, management with endoscopic incision of orthotopic ureterocele is safe and effective. VUR may occur in a few cases.  (+info)

Ureterocele containing a stone in a duplex system. (8/14)

The formation of calcified stone in the ureterocele, a frequent event in adults, is very uncommon in a pediatric age. We present a case of a ureterocele containing a calcified stone in an 8-year-old girl. The diagnosis was made with radiological investigations (intravenous pyelogram, ultrasonography and, eventually, voiding cystourethrogram). Meatostomy and calculus extraction, or open surgery in more complicated cases, are the treatments of choice.  (+info)

A ureterocele is a congenital abnormality of the urinary system, specifically involving the ureter. It is characterized by a sac-like dilation or expansion of the distal end of the ureter as it enters the bladder. Ureters are tubes that carry urine from the kidneys to the bladder. When a ureterocele occurs, the affected ureter's opening into the bladder is narrowed or obstructed, leading to the dilation of its terminal portion.

Ureteroceles are more commonly found in females than males and can be associated with other urological anomalies such as duplex kidneys (having two separate ureters draining a single kidney). Ureteroceles may cause various symptoms, including urinary tract infections, incontinence, or kidney problems, depending on their size and location. Treatment typically involves surgical correction to alleviate the obstruction and prevent further complications.

Urologic surgical procedures refer to various types of surgeries that are performed on the urinary system and male reproductive system. These surgeries can be invasive (requiring an incision) or minimally invasive (using small incisions or scopes). They may be performed to treat a range of conditions, including but not limited to:

1. Kidney stones: Procedures such as shock wave lithotripsy, ureteroscopy, and percutaneous nephrolithotomy are used to remove or break up kidney stones.
2. Urinary tract obstructions: Surgeries like pyeloplasty and urethral dilation can be done to correct blockages in the urinary tract.
3. Prostate gland issues: Transurethral resection of the prostate (TURP), simple prostatectomy, and robotic-assisted laparoscopic radical prostatectomy are some procedures used for benign prostatic hyperplasia (BPH) or prostate cancer.
4. Bladder problems: Procedures such as cystectomy (removal of the bladder), bladder augmentation, and implantation of an artificial urinary sphincter can be done for conditions like bladder cancer or incontinence.
5. Kidney diseases: Nephrectomy (removal of a kidney) may be necessary for severe kidney damage or cancer.
6. Testicular issues: Orchiectomy (removal of one or both testicles) can be performed for testicular cancer.
7. Pelvic organ prolapse: Surgeries like sacrocolpopexy and vaginal vault suspension can help correct this condition in women.

These are just a few examples; there are many other urologic surgical procedures available to treat various conditions affecting the urinary and reproductive systems.

Vesico-Ureteral Reflux (VUR) is a medical condition that affects the urinary system, specifically the junction where the ureters (tubes that carry urine from the kidneys to the bladder) connect with the bladder. In normal physiology, once the bladder fills up with urine and contracts during micturition (urination), the pressure within the bladder should prevent the backflow of urine into the ureters.

However, in VUR, the valve-like mechanism that prevents this backflow does not function properly, allowing urine to flow backward from the bladder into the ureters and potentially even into the kidneys. This reflux can lead to recurrent urinary tract infections (UTIs), kidney damage, and other complications if left untreated. VUR is more commonly diagnosed in children but can also occur in adults.

A ureter is a thin, muscular tube that transports urine from the kidney to the bladder. In humans, there are two ureters, one for each kidney, and they are typically about 10-12 inches long. The ureters are lined with a special type of cells called transitional epithelium that can stretch and expand as urine passes through them. They are located in the retroperitoneal space, which is the area behind the peritoneum, the membrane that lines the abdominal cavity. The ureters play a critical role in the urinary system by ensuring that urine flows from the kidneys to the bladder for storage and eventual elimination from the body.

Ureterostomy is a surgical procedure that creates an opening from one or both ureters, the tubes that carry urine from the kidneys to the bladder, to the abdominal wall. This allows urine to bypass the bladder and be expelled through the opening, called a stoma, into a collection device or onto the skin where it can be absorbed by a pad or diaper.

Ureterostomy is typically performed as a temporary measure in cases of severe bladder injury, infection, or obstruction that cannot be immediately corrected. It may also be used as a permanent solution for patients with congenital abnormalities or conditions that prevent the normal flow of urine through the bladder.

There are two main types of ureterostomy: cutaneous and uretero-cutanoeostomy. In a cutaneous ureterostomy, the ureter is brought directly to the abdominal wall and sutured in place. In a uretero-cutanoeostomy, a piece of intestine is used to create a conduit between the ureter and the abdominal wall.

Like any surgical procedure, ureterostomy carries risks such as bleeding, infection, and injury to surrounding organs. Patients who undergo this procedure will require close monitoring and follow-up care to ensure proper healing and function of the stoma.

"California" is a geographical location and does not have a medical definition. It is a state located on the west coast of the United States, known for its diverse landscape including mountains, beaches, and forests. However, in some contexts, "California" may refer to certain medical conditions or situations that are associated with the state, such as:

* California encephalitis: a viral infection transmitted by mosquitoes that is common in California and other western states.
* California king snake: a non-venomous snake species found in California and other parts of the southwestern United States, which can bite and cause allergic reactions in some people.
* California roll: a type of sushi roll that originated in California and is made with avocado, cucumber, and crab meat, which may pose an allergy risk for some individuals.

It's important to note that these uses of "California" are not medical definitions per se, but rather descriptive terms that refer to specific conditions or situations associated with the state.

"Nursing libraries" refer to collections of resources specifically curated to support the education, research, and practice of nursing professionals. These libraries can include various formats of materials such as books, journals, electronic databases, multimedia resources, and more. They may be physical spaces within nursing schools or healthcare institutions, or they may exist virtually as online repositories. The primary goal of nursing libraries is to facilitate evidence-based practice, lifelong learning, and knowledge translation for nurses and other members of the interprofessional healthcare team.

A kidney, in medical terms, is one of two bean-shaped organs located in the lower back region of the body. They are essential for maintaining homeostasis within the body by performing several crucial functions such as:

1. Regulation of water and electrolyte balance: Kidneys help regulate the amount of water and various electrolytes like sodium, potassium, and calcium in the bloodstream to maintain a stable internal environment.

2. Excretion of waste products: They filter waste products from the blood, including urea (a byproduct of protein metabolism), creatinine (a breakdown product of muscle tissue), and other harmful substances that result from normal cellular functions or external sources like medications and toxins.

3. Endocrine function: Kidneys produce several hormones with important roles in the body, such as erythropoietin (stimulates red blood cell production), renin (regulates blood pressure), and calcitriol (activated form of vitamin D that helps regulate calcium homeostasis).

4. pH balance regulation: Kidneys maintain the proper acid-base balance in the body by excreting either hydrogen ions or bicarbonate ions, depending on whether the blood is too acidic or too alkaline.

5. Blood pressure control: The kidneys play a significant role in regulating blood pressure through the renin-angiotensin-aldosterone system (RAAS), which constricts blood vessels and promotes sodium and water retention to increase blood volume and, consequently, blood pressure.

Anatomically, each kidney is approximately 10-12 cm long, 5-7 cm wide, and 3 cm thick, with a weight of about 120-170 grams. They are surrounded by a protective layer of fat and connected to the urinary system through the renal pelvis, ureters, bladder, and urethra.

Acridine Orange is a fluorescent dye commonly used in various scientific applications, particularly in the field of cytology and microbiology. Its chemical formula is C17H19N3O.

In medical terms, Acridine Orange is often used as a supravital stain to differentiate between live and dead cells or to identify bacteria, fungi, and other microorganisms in samples. It can also be used to detect abnormalities in DNA and RNA, making it useful in the identification of certain types of cancerous cells.

When exposed to ultraviolet light, Acridine Orange exhibits a green fluorescence when bound to double-stranded DNA and a red or orange-red fluorescence when bound to single-stranded RNA. This property makes it a valuable tool in the study of cell division, gene expression, and other biological processes that involve nucleic acids.

However, it is important to note that Acridine Orange can be toxic to living cells in high concentrations or with prolonged exposure, so it must be used carefully and in accordance with established safety protocols.

Molecular typing is a laboratory technique used to identify and characterize specific microorganisms, such as bacteria or viruses, at the molecular level. This method is used to differentiate between strains of the same species based on their genetic or molecular differences. Molecular typing techniques include methods such as pulsed-field gel electrophoresis (PFGE), multiple-locus variable number tandem repeat analysis (MLVA), and whole genome sequencing (WGS). These techniques allow for high-resolution discrimination between strains, enabling epidemiological investigations of outbreaks, tracking the transmission of pathogens, and studying the evolution and population biology of microorganisms.
