Patients who are frequent stone formers should have serum parathyroid hormone and calcium levels taken to evaluate for hyperparathyroidism. They should also have citrate levels and uric acid levels as well as a 24-hour urine study. The stones are then broken into smaller frag ments, so that the patient can pass them. Steinstrasse syndrome is a large quantity of stone fragments, which may accumulate and block the ureter. Ureteroscopy is a method in which a small-caliber instrument called a ureteroscope is advanced into the ureter and into the kidney. The stone can then be retrieved with a basket or grasper and endoscopically removed from the urinary tract. Percutaneous nephrolithotripsy is a method for stone removal that is usu ally reserved for patients with a staghorn calculus, a significant stone burden, or any stones that the surgeon is unable to remove with the afore mentioned methods. Open surgery for stone retrieval has largely fallen out of favor, secondary to the invasive nature of this procedure. It is formed by the division of the cloacae into an anal canal posteriorly and a uro genital sinus anteriorly. Three layers of muscle make up the bladder: the inner longitudinal layer, the middle circular layer, and the outer longitudinal layer. The inside view of the bladder includes the lateral walls of the bladder, dome of the bladder, and the triangular base of the bladder, which is known as the trigone. The ureteral orifices are the two holes by which the ureters are connected to the bladder. The arterial supply of the bladder is supplied by the inferior vesical and supe rior vesical artery. This is the presenting symptom in about 90% of patients with newly diagnosed T C C. Patients may also have irritative voiding symptoms, also known a s lower urinary tract symptoms. Imaging studies may find a suspicious bladder wall thickening or a large bladder mass. This procedure is performed by inserting a resectoscope through the urethra and into the bladder. The patient should have surveillance cystoscopy every 3 months for 2 years, then every 6 months for 2 more years, and then every year thereafter. This is a very effective therapy for patients with carcinoma in situ to prevent recurrence. Partial cystectomy is a procedure for removing the part of the bladder that is affected by the tumor. This procedure includes removal of the prostate and seminal vesicles in men and removal of the uterus, cervix, and ovaries in women. There are many methods of diver sion; including continent diversions, as well as the more common noncon tinent urostomies such as the ileal conduit. The ileal conduit is the most common choice for urinary diversion in the United States. Neurogenic bladder is the loss of normal function of the bladder secondary to damage to part of the nervous system. Causes include any disease process that can damage the nerve fibers that innervate the bladder. These include traumatic spinal cord inj ury, spinal cord neoplasm, spina bifida, stroke, multiple sclerosis, cerebral palsy, Parkinson disease, and others. Clinical features: Symptoms include urinary incontinence, urinary retention, frequent urinary tract infections, pyelonephritis, urinary urgency, and urinary frequency. The standard test for diagnosis of neurogenic bladder is cystoscopy with com plex urodynamics. The urodynamics procedure is performed by inserting a urethral catheter and placing electrodes on the perineum to assess the contractions of acces sory muscles and the detrusor contraction, during filling as well as voiding. Clean intermittent catheterization is an excellent way of managing a patient with urinary retention and neurogenic bladder. Patients are instructed to void on their own and then to catheterize themselves to remove the post void residual urine in their bladder. Anticholinergic therapy is used to decrease the bladder contractility and thus to decrease the amount of involuntary bladder contractions. Prophylactic antibiotics may be considered for patients with recurrent uri nary tract infections. Bladder augmentation is performed to increase the bladder size with acces sory tissues. Paralytic agents such as botulinum toxin may be inj ected to relax the ure thral sphincter. Findings at cystoscopy include glomerulations (submucosal hemorrhages) on the bladder mucosa. These include the presence of a fastidious infectious organism and that the condi tion results from an autoimmune disfunction. The current theory is that the condition results from a defect in the glycosaminoglycan layer of the bladder mucosa.

Symptoms worsen with lumbar extension (standing) and improve with lumbar flexion (sitting bacteria chlamydia trachomatis order colcout cheap online, leaning forward). Neurogenic claudication symptoms slowly resolve with rest, whereas vascular claudication symptoms resolve more quickly with rest. Distinguish neurogenic claudication from vascular claudication based on history and physical exam. Nonsurgical treatments include anti-inflammatory medications, physical ther apy for flexion/extension strengthening, weight loss, and activity modification. B utto c k and leg p a i n that i m p roves with flexion I gro c e r y c a rt sig n) is a symptom of l u m b a r ste n o s i s. Disc herniations are acute or chronic tears in the disc annulus that can lead to extrusion of the nucleosis pulposus, causing impingement of lumbar spinal roots. Most herniations are asymptomatic, and most asymptomatic herniations resolve without any treatment. They are more common in males and occur most frequently between the ages of 30 and 5 0 years old. Ninety-five percent of disc herniations are at L4/L5 and L5/S l discs, with the latter being more common. L4- L5 d i s c h e rniation u s u a l l y affects the L5 n e rve ro ot, whereas L5-Sl disc hernia t i o n s u s u a l ly affect the S l n e rve root. The n o r m a l e p i d u r a l fat has been d i s p l a c e d by the disc material, o b s c u ri n g the far lateral recess. P h i l a d e l p h i a, P A: Li p p i n c ott W i l l i a m s & W i l k i n s; 2004. Paracentral disc herniation will affect traversing nerve root (nerve root from level below disc), whereas far lateral disc herniation will affect exiting nerve root (nerve from level above disc) as seen in Figure 1 5 - 1 3. Most commonly, these patients will present with sciatica (radicular extremity pain), but beware of cauda equina syndrome. A full neurologic examination will be needed but deficits would be as seen in Clinical Pearl 1 5-6. A straight-leg raise is positive with reproduction of radicular pain between 30 and 70 degrees of hip flexion with knee fully extended. Lumbar spine radiographs should be ordered to rule out other diagnoses and may show disc space narrowing or other degenerative changes. Nonemergent orthopedic referral for continued symptoms despite nonsurgical treatment. Nerve root block with steroid inj ections may be used for refractory or severe cases for pain control. Lumbar discectomy (remove the extruded disc from the spinal canal) would be considered for large herniations and patients with recalcitrant symptoms. These procedures are most helpful for radicular pain and may not alleviate the back pain component of symptoms. These are vertebral body fractures that are the most common osteoporotic fracture in the elderly. The fractures are most common in lower thoracic and upper lumbar vertebral bodies. With one fragility fracture, the risk of future fragility fractures (compression fracture, distal radius fracture, and femoral neck fracture) increases significantly over time. Patient may give history of very minor trauma such as twisting in chair or lifting small child. Back pain and tenderness to palpation will be present at area of compression fracture. Make sure to elicit personal and family history of cancer, constitutional symptoms, or infection. C o m p r e s s i o n fractures a r e c o m m o n l y the f i r s t s i g n of oste o p o ro s i s.

N ote the foc a l depression of the superior endplate Iarrow) of the T l O vertebral body, with a displaced a nterior fracture fra gment (arrowhead). A characteristic tra pezoid a l vertebral shape has been formed owing to a nterior compression of the superior vertebral endplate. The usual precipitating force is a n anterior com pression injury focusing the compressive forces to the a nterior aspect of the vertebral body. Observe that the most nota ble features are a d e c rease in vertebral height, with a p p roximation of the vertebral endplates, and associated lateral displacement of the verte bral body margins (arrow). Nonsurgical treatments include anti-inflammatory medications, physical ther apy strengthening and stretching once acute pain has decreased, and activity modification. With osteoporotic fractures, medical management of osteoporosis is indicated by either a primary care physician or rheumatologist. Surgical treatment is indicated for patients who have failed a 6-week course of the nonsurgical treatments described earlier without symptom relief. Kyphoplasty, inj ection of cement into the vertebral body, may be performed at that time but is only indicated for pain relief because this procedure does not correct kyphotic deformity. The most common type of Chiari malformation is downward herniation of the fourth ventricle and the cerebellar tonsils. Patients may present with bulging fontanelles, dilation of scalp veins, and increased head circumference. Parinaud syndrome (altered upward gaze), nausea, vomiting, ataxia, lethargy, and irritability may result. Ventriculoatrial shunts may be considered in very small infants because of the smaller absorptive surface of their peritoneum.

Local excision: reserved for small, well-differentiated lesions that involve the submucosa only, or for poor-risk patients 2. Abdominoperineal resection: Five-year survival averages 50%, with 25% to 30% local recurrence after surgery. In the upper anal canal, there are three cushions of submucosal tissue com posed of connective tissue containing venules and smooth muscle fibers. Usually, there are three cushions: left lateral, right anterior, and right posterior. During defecation, they become engorged with blood, cushion the anal canal, and support the lining of the canal. Muscles that arise partly from the internal sphincter and partly from the conj oint longitudinal muscle support the anal cushions. Hemorrhoid is the term used to describe the downward displacement of the anal cushions, causing dilatation of the contained venules, and they develop when the supportive tissues of the anal cushions deteriorate. External hemorrhoids are dilated venules of the inferior hemorrhoidal plexuses below the dentate line. Internal hemorrhoids are the anal cushions located above the dentate line that have become prolapsed. Second degree: the anal cushions prolapse through the anus on straining but spontaneously reduce. Third degree: the anal cushions prolapse through the anus on straining or exertion and require manual replacement into the anal canal. The most common manifestation is painless, bright red rectal bleeding associated with bowel movements. The common complaints of burning, itching, swelling, and pain are usually not from hemorrhoids but from pruritus ani, anal abrasion, fissure, thrombosed external hemorrhoids, or prolapsed anal papilla. Patients with thrombosed external hemorrhoids present with abrupt onset of a mass and pain. Most patients with thrombosed external hemorrhoids do not give a history of straining, physical exertion, or hemorrhoids. In chronic prolapse, exposed rectal mucosa often causes perianal irritation and mucus staining on the underwear. According to modern concepts, prolapse of the anal cushions is initiated by the shearing effect of the passage of a large, hard stool, or by the precipitous act of defecation, as in urgent diarrhea. If prolapse of the vascular cushion can be prevented, the anal cushions return to their normal state, and symptoms are ameliorated. Rubber band ligation is suitable for first-degree and second-degree hemor rhoids that do not respond to bulk-forming agents. Infrared photocoagulation coagulates tissue protein or evaporates water in the cells. Hemorrhoidectomy is considered when hemorrhoids are severely prolapsed, requiring manual reduction, or when they are complicated by associated pathology such as ulceration, fissures, fistulas, large hypertrophied papilla, or excessive skin tags. Stapled hemorrhoidopexy can be attempted for second- or third-degree hemor rhoids; however, this procedure has been associated with the development of pelvic sepsis in rare cases. Treatment of thrombosed external hemorrhoids is aimed at prevention of recurrent clot, relief of severe pain, and prevention of residual skin tags. If pain is subsiding, conservative treatment is with sitz baths, proper anal hygiene, and bulk-forming agents. If strangulated hemorrhoids are untreated, they progress to ulceration and necrosis. The primary fissure occurs without association with other local or systemic diseases. The secondary fissure occurs in association with Crohn disease, leukemia, or aplastic anemia. Most tears of the anal canal can be traced to the passage of large, hard stool or explosive diarrhea, trauma to the anus, or a tear during vaginal delivery. In men, almost all fissures are located in the posterior midline, whereas in women, 1 0% are in the anterior midline. Patients have increased anal resting pressure caused by the increased tone of the internal sphincter muscle. Chronic fissures have a triad of a fissure, sentinel skin tag, and hypertrophied anal papilla. Initial treatment of acute anal fissure is pain relief with proper anal hygiene and warm sitz baths to relax the anal canal. Nitroglycerin ointment or calcium-channel blockers applied topically help by decreasing sphincter resting tone. Fissures or ulcers in Crohn disease are larger and deeper than primary anal fis sures. Treatment consists of proper anal hygiene and treatment of the underlying inflammatory disease. In the wall of the anal canal, a variable number of anal glands (4 to 10) lined by stratified columnar epithelium have direct openings into the anal crypts at the dentate line.
