Description

Although the reproducibility and clinical utility of the Whitaker test have been questioned (Djurhuus et al hiv infection early symptoms generic acivir pills 200 mg free shipping, 1985), the test recently has been shown to determine or contribute to therapeutic management in 84% of cases of suspected obstruction and to accurately predict both obstruction and nonobstruction in 77% of cases (Lupton and George, 2010). A study by Veenboer and de Jong in 2011 demonstrated a 100% negative predictive value in the ability of the Whitaker test to diagnose the absence of obstruction. Although the Whitaker test has limited applicability in clinical practice, it continues to have a valuable role in the evaluation of equivocal upper urinary tract obstruction, especially when noninvasive investigations are inconclusive. The incidence of nephrogenic systemic fibrosis in patients with risk factors has been demonstrated to be 3%, and new recommendations now limit the use of gadolinium in patients with renal impairment (Cerwinka and Kirsch, 2010). Retrograde Pyelography Retrograde pyelography refers to the injection of contrast into the upper collecting system through a cystoscopic approach. The technique accurately defines ureteral and upper collecting system anatomy and can determine the location of an obstructive lesion. It is most often used to define the anatomy of the collecting system when it has not been adequately defined by other imaging modalities or when a patient has risk factors for receiving iodinated contrast material. Because retrograde pyelography involves intubation of the ureter with a catheter, bacteria may be introduced into the upper urinary tract during the procedure. Excretory Urography Excretory urography was previously considered the imaging modality of choice in the evaluation of patients suspected of having urolithiasis and/or urinary tract obstruction. Imaging during excretory urography depends on glomerular filtration and renal excretion of iodinated contrast medium; therefore the utility of excretory urography is limited in patients with renal insufficiency. Excretory urography should not be performed in patients with a history of contrast allergy or those in whom radiation exposure is a concern. A delay in contrast uptake and excretion by the kidney (delayed nephrogram) can be indicative of urinary tract obstruction, and the subsequent opacification of the collecting system with contrast can be helpful in identifying the level and potentially the source of obstruction. In addition, small renal size, parenchymal thinning, calyceal clubbing, and significant ureteral dilation and tortuosity can be signs of chronic urinary tract obstruction. Antegrade Pyelography Antegrade pyelography is most often used when retrograde pyelography is not technically feasible or when other imaging studies do not adequately define the collecting system. The mechanism of obstruction-induced increased afferent arteriolar resistance was initially thought to be due to upregulation of the renin-angiotensin system or increased thromboxane A2 expression, but subsequent studies have not revealed a significant effect of these mediators on the renal hemodynamic response to obstruction (Vaughan et al, 2004). The mechanism of these hemodynamic differences appears to be related to the site of vasoconstriction in the glomerulus. It also decreases the sensitivity of tubuloglomerular feedback, inhibits release of renin, and increases the glomerular ultrafiltration coefficient Kf, which is related to the surface area and permeability of the capillary membrane. A major problem with studies involving partial obstruction is the ability to accurately reproduce the degree of obstruction in each animal. Thornhill and associates (2005) describe a method of ligating the ureter over a wire of calibrated diameter, which then can be removed to create a partial obstruction. A rupture of the calyceal fornix and subsequent extravasation of urine can occur during acute obstruction, typically in response to ureteral stones (Stenberg et al, 1988), although it also can be seen with congenital abnormalities such as posterior urethral valves. Extravasation of urine into the venous and lymphatic system also may occur in the setting of urinary obstruction.

Moreover hiv infection rate minnesota acivir pills 200 mg purchase amex, complete stone removal appears to decrease the risk of stone recurrence (Singh et al, 1975; Patterson et al, 1987; Newman et al, 1988). Residual fragments are most likely to pass when located within the ureter, and least likely to pass when located in the lower pole. A similar spontaneous passage rate of 25% to 30% has been reported by others (Streem and associates, 1997; Candau et al, 2000). Fragments larger than 2 mm in greatest diameter were more likely to undergo a secondary procedure and independently predicted a postoperative stone-related event. Similarly, fragments located in the renal pelvis and ureter were associated with a stone event on multivariate analysis but also were associated with the highest likelihood of spontaneously passing (Ganpule et al, 2009; Raman et al, 2009). However, this must be balanced with the need to minimize unnecessary radiation exposure in patients.

Specifications/Details

Before the era of minimally invasive stone treatments hiv infection rate in egypt acivir pills 200 mg purchase visa, asymptomatic and minimally symptomatic stones were not actively removed, given the high morbidity associated with treatment. Although some small, asymptomatic renal stones may never require treatment, a review of the known behavior of such stones suggests that many will grow over time, become symptomatic, and ultimately require treatment. Before the era of endourology, stones were removed via open stone surgery, which provided high stone-free rates but came with a high rate of complications. More recently, in experienced hands, it has been demonstrated that laparoscopic and roboticassisted renal stone surgery can be safely used in selected patients with good outcomes. In areas where endourologic technology is widely available, open stone surgery is pursued only 1% of the time or less, and even in developing countries open stone surgery rates have dropped dramatically from 26% to 3. Deciding on the optimal treatment for a given patient is not always clear and depends on many variables, which can be broadly lumped into stone-related factors, renal anatomic factors, and clinical factors (Box 53-1). The combination of these factors, availability of technology and equipment, and familiarity of the urologist with the different surgical techniques ultimately determines which treatment is preferred for a given patient. Nonstaghorn Renal Calculi A number of studies have reviewed the fate of asymptomatic renal stones while under observation; however, the longest follow-up for any of these series is approximately 10 years, with the majority of them following patients for less than 5 years. Thus the true natural history of asymptomatic renal stones over an extended time period is unknown. Most studies evaluating this type of stone presentation report the rate of spontaneous passage, the rate of intervention, and the rate of stone progression, often defined as stone growth, development of symptoms, or need for intervention. Of this cohort, spontaneous passage was seen in 16%, whereas 40% required surgerical intervention. Similar results were found by Glowacki and colleagues (1992), with 32% of initially asymptomatic renal stones becoming symptomatic. In 1887, Czerny was the first to approximate the cut edges of the incised kidney with suture to control hemorrhage and to prevent fistula formation. In the same year, Guyon reported that nephrectomy, although efficacious in curing patients with calculus pyonephrosis, was more dangerous than nephrolithotomy because lithiasis was often bilateral (Wershub, 1970). In 1889 Kümmell was the first surgeon to perform a partial nephrectomy for calculus pyonephrosis (Redman, 1983). Lower, in 1913, revived interest in pyelolithotomy when he suggested that this technique might be a safer and easier method of removing renal calculi than nephrolithotomy. Although several small series of cases indicated that there might be a higher incidence of stone recurrence after pyelolithotomy, other studies showed that recurrence was no more common than it was after nephrolithotomy (Murphy, 1972). These findings, in conjunction with rapid advancements in the field of radiography, brought about a decided preference for pyelolithotomy (Gil-Vernet and Culla, 1981). In 1943 Dees and Fox reported the first use of coagulum to remove small stones and stone fragments from the renal pelvis and calyces (Marshall, 1983). Fibrinogen and thrombin were used to make a coagulum that was injected into the renal pelvis and produced a flexible cast of the pelvis and calyces. The use of this technique was limited initially owing to the scarcity of materials and the risk of blood-borne disease transmission. However, interest in coagulum pyelolithotomy was renewed when cryoprecipitate was found to be a safe and readily available source of concentrated fibrinogen (Fischer et al, 1980).

Customer Reviews

Rune, 27 years: Near the bladder, the terminal ureter is enveloped by a muscular layer, the Waldeyer sheath, and then pierces the bladder wall obliquely as the intramural segment. Birt-Hogg-Dubé Syndrome Birt-Hogg-Dubé syndrome, in which patients develop cutaneous fibrofolliculomas, lung cysts, spontaneous pneumothoraces, and a variety of renal tumors primarily derived from the distal nephron, is named after three Canadian physicians who first described the cutaneous lesions in 1977 (Pavlovich et al, 2005; Adley et al, 2006). Rho-kinase inhibits myosin phosphatase by phosphorylation of its regulatory subunit, which prevents dephosphorylation of myosin light chain, which in turn leads to Ca2+ sensitization of the smooth muscle with subsequent increase in contractility.

Tukash, 48 years: Lastly, cytotoxic agents promote a high cell turnover, resulting in urinary excretion of large amounts of uric acid. Another study found that the presence of calculi does not correlate with the severity of prostatitis symptoms on validated questionnaires; however, the duration of reported symptoms is positively correlated with the presence of prostatic stones. Essential to this process are nucleation, growth, and coalescence of flaws within the stone caused by a tensile or shear stress.

Bufford, 60 years: Various lithotripters have been used, including ultrasonic handpieces, lasers, pneumatic devices, and electrohydraulic probes. The height of the irrigant during rigid nephroscopy should be maintained at 80 cm or less above the patient to minimize intrapelvic pressure and to prevent fluid absorption through pyelovenous backflow (Miller and Whitfield, 1985). Ipsilateral rib fracture can increase the incidence of significant renal trauma threefold.

Nemrok, 57 years: These stones can be managed through an open or laparoscopic vesiculectomy, or the stone can be retrieved endoscopically using a small-caliber ureteroscope (Ozgök et al, 2005; Cuda et al, 2006; Han et al, 2008). Onset of hypertension before age 20 (early onset) or after age 50 (late onset), particularly in those without a family history of hypertension 4. Therefore it appears cystoscopically to be more deeply colored than the rest of the bladder.

Gunnar, 58 years: The acute evaluation of a pregnant woman with suspected renal colic begins with a thorough history and physical examination. Zhong and coworkers (2001) suggested that it is expansion of the bubbles in a vessel that will lead to rupture of the wall of that blood vessel, testing this in an in vitro setting. Pulling of the penis is considered by some to be pathognomonic, because it indicates the child is suffering from stranguria; frank urinary retention, however, is rare.

Hanson, 64 years: This discrepancy in numbers may be the result of selection of patients, with more high-grade and dysplastic tumors reported in these series. There are a few amino acids that have specialized transporters, and some are Na independent. Future prospective studies may help provide insight into their utility as clinical prediction tools.

Harek, 32 years: Potassium-magnesium citrate versus potassium chloride in thiazide-induced hypokalemia. In addition, the toxicities of these agents may limit their usefulness in the adjuvant setting because patients taking a potentially preventive treatment tend to have a much lower threshold for toxicities. The time constant of the guinea pig ureter as measured by extracellular stimulation is 200 to 300 msec (Kuriyama et al, 1967).

Kalesch, 61 years: Leaks manifest in the early postoperative period with decreased urine output from the urinary catheter and increased output from the closed suction drain. Obstructive uropathy always should be considered in patients with new-onset hypertension and in patients with renal failure without a history of renal disease, diabetes, or hypertension. When supracostal puncture is performed, the risk for pneumothorax or pleural effusion requiring drainage can vary widely from 1.
