How serious can calculi be?

We found a low prevalence (1.3%) of concomitant disease in patients with stone formation in this center. Patients with obstructive jaundice and those who have two or more risk factors for stone formation should undergo computed tomography scan.

Anonymous Patient Answer

What causes calculi?

The current findings suggest that urolithiasis is due to a combination of biochemical factors, genetic factors, and environmental factors. The combination of two, three or more factors may account for only 50% to 60% of cases. A detailed evaluation of familial and environmental causes is required to better categorize cases of urolithiasis, with special emphasis on familial urolithiasis.

Anonymous Patient Answer

How many people get calculi a year in the United States?

Approximately 0.15 million people will be diagnosed with a calculus in the first year of this study; most will be between the ages of 20 and 50; the average age of diagnosis for men is 56.4 years; and most will be non-Hispanic white (82%) or Hispanic (12%).

Anonymous Patient Answer

What are common treatments for calculi?

Some calculi present with no symptoms, and management of such incidental findings can be conservative. Symptomatic stones are usually eliminated or impacted with surgery, which may be curative in up to 50% of cases. Surgical treatment may consist of open surgery, endoscopic surgery, or robot-assisted laparoscopic urological surgery. In case of recurrent calculi or when conservative treatment does not suffice, renal extracorporeal shock wave lithotripsy and electroshock lithotripsy have been found to be effective, though the latter is more preferred for larger stones (<2 cm).

Anonymous Patient Answer

Can calculi be cured?

Occurrence of calculi in the urinary tract of patients with rhabdomyolytic calculi can be reduced by careful followup of patients for the treatment of calculi and prompt treatment of abnormal findings. Treatment depends on the composition. Small stones, which might be visible in ultrasonography, should be treated with medical treatments rather than radical surgery.

Anonymous Patient Answer

What are the signs of calculi?

Stones may be painful but only rarely give no pain in most cases. The appearance of calculi on x-rays is also a common finding. Radiography will usually confirm a diagnosis of a calculus (or calculus of the ureter) if there is clinical or other evidence for it.

Anonymous Patient Answer

What is calculi?

Calculi are common in the general population and are a cause of significant morbidity in many geographical areas. They are often asymptomatic. Appropriate diagnostic imaging is an important issue, but guidelines for the investigation of symptomatic patients are non-existent and, in this author's opinion, there is a need for a clinical protocol.

Anonymous Patient Answer

Who should consider clinical trials for calculi?

Data from a recent study of this study found that nearly one third of the patients in this cohort had evidence of significant calcium disease. This information should be considered when deciding which patients should be invited to enroll in an appropriate clinical trial. Inclusion criteria for randomized double-blind clinical trials should be updated to include all patients with evidence of significant calcium disease as they are at greatest risk of poor renal outcome. If randomized controlled trials for calcium stone disease are performed, it is important to incorporate measurements of calcium burden and renal function.

Anonymous Patient Answer

What does laparoscopic cholecystectomy with fluorescent cholangiography usually treat?

LCM has been known to be not only a diagnostic procedure but also a therapeutic modality. This article proposes the view that LCM with cholangiography, which has the right combination of modalities to treat calcular gallstone disease, will be useful in the future.

Anonymous Patient Answer

Is laparoscopic cholecystectomy with fluorescent cholangiography safe for people?

Laparoscopic cholecystectomy with cholangiography is a safe and effective method for the evaluation of bile duct for the purposes of diagnosis or treatment of suspected common bile duct stones.

Anonymous Patient Answer

Is laparoscopic cholecystectomy with fluorescent cholangiography typically used in combination with any other treatments?

Our current practice is to perform cholecystectomies after ERCP using FNAB. Since our experience is limited, this procedure can be performed in the setting of an ERCP in the setting of standardization of methodology and a careful post cholangiographic follow up.

Anonymous Patient Answer

How does laparoscopic cholecystectomy with fluorescent cholangiography work?

Compared with LCG, the laparoscopic approach (LLCG) has shorter onset time and earlier return to normal everyday activities. It is associated with less postoperative pain and shorter postoperative hospital stay. It also enables diagnosis of choledocholithiasis, with consequent avoidance of endoscopic sphincterotomy. The diagnostic accuracy of the technique, especially for intrahepatic cholangiocarcinoma, is similar to that of LCG. The authors recommend LLLCG be performed when patients with symptoms of biliary disease are submitted to cholecystography.
