1/12. Use of ketorolac in renal colic.Intravenously administered ketorolac tromethamine provided complete pain relief to a 54-year-old man with right-sided testicular pain and nausea and vomiting. The patient had a ureteral calculus documented by computed tomography. This patient's pain initially failed to respond to intravenously administered hydromorphone hydrochloride. Subsequently, he was admitted to the hospital and had operative removal of his ureteral calculus and placement of a ureteral stent. Based on their findings and review of the literature, the authors recommend that intravenous ketorolac be used as the first-line treatment for acute renal colic in patients in whom the medication is not contraindicated.- - - - - - - - - - ranking = 1keywords = ureteral calculus, calculus (Clic here for more details about this article) |
2/12. An unusual cause of renal colic: hydatiduria.Hydatid disease of the urinary tract is seen rarely. Hydatiduria may be a finding of renal involvement, but it is a rare cause of renal colic. A case is reported of renal hydatid disease that was diagnosed during the investigation of renal colic. A 38-year-old woman presented with renal colic. She had a history of episodes of renal colic and occasional voiding of grape-like material. No calculus was found in the urinary tract by plain film or ultrasonographic examination. The histopathologic examination of this material revealed daughter cysts that are pathognomonic for hydatid disease. Ultrasound and computed tomography confirmed this diagnosis and right nephrectomy was performed without cyst perforation or any spilling of cyst content. albendazole, 10 mg/kg per day, was given for 4 weeks (2 weeks preoperatively and 2 weeks postoperatively).- - - - - - - - - - ranking = 0.0027357887858745keywords = calculus (Clic here for more details about this article) |
3/12. Pyelocalyceal diverticulum: an unusual cause of acute renal colic.The differential diagnosis of acute flank pain includes kidney stones, urinary tract infection, dissecting abdominal aortic aneurysm (AAA), arterial or venous compromise of the kidney, renal abscess, renal carcinoma, and papillary necrosis. This is a report of an unusual cause of renal colic: pyelocalyceal diverticulum. Stasis of urine within a diverticulum promotes both calculus formation and urinary tract infection, either of which can lead to colic. Several radiographic findings may suggest a calyceal diverticulum, including, on plain X-ray, a very peripheral or mobile renal calculus, or on intravenous pyelogram, an early filling-defect and delayed or retained filing of a circular or ovoid mass.- - - - - - - - - - ranking = 0.005471577571749keywords = calculus (Clic here for more details about this article) |
4/12. The secret of the phantom stone: a case report.A 50-year old man, who has a history of allergies to i.v. contrast and NSAID, was presented with right renal colic. He was treated with regular opiate injections. Plain abdominal X ray showed a 1 cm opacity at the level of L2 but spiral CT failed to locate the urinary calculus. Abdominal examination revealed a small piece of metal implanted in the subcutaneous anterior abdominal wall which was also subsequently identified on CT scanning. When the opiate treatment was withdrawn, the patient absconded.- - - - - - - - - - ranking = 0.0027357887858745keywords = calculus (Clic here for more details about this article) |
5/12. Management of gestational nephrolithiasis in the presence of a bicornuate uterus and pelvic kidney.A 39-year-old para 0( 1) woman with known nephrolithiasis within a left-sided pelvic kidney presented with left-sided renal colic at 7 weeks gestation. She had a previous miscarriage due to a bicornuate uterus. Ultrasound and magnetic resonance urography confirmed an incomplete obstruction of the left upper renal tract which was relieved by percutaneous nephrostomy. She presented again at 14 weeks with renal colic and minimal output. An ultrasound confirmed recurrent hydronephrosis and a nephrostogram showed that the catheter had retracted almost completely from the collecting system. This was considered to be due to the upward pressure of the enlarging uterus on the catheter, which had been fixed externally to the skin. This problem was obviated by not securing the replacement nephrostomy tube to the skin. She developed pre-eclamptic toxaemia and gave birth at 35 weeks gestation by caesarean section. The calculus was later dissolved using extra-corporeal shockwave lithotripsy.- - - - - - - - - - ranking = 0.0027357887858745keywords = calculus (Clic here for more details about this article) |
6/12. Prophylaxis of uric acid stones with alternate day doses of alkaline potassium salts.uric acid stone formation ordinarily is prevented by increases in the urinary pH after meals. This postprandial alkaline tide is lost in patients who make such calculi. Single dose, alternate day administration of an alkaline potassium salt will increase urinary pH and simulate this normal physiological mechanism. An important part of the regimen is patient self-monitoring to verify that the urinary pH increases to greater than 6.8, 1 1/2 to 2 hours after the medication is taken. In contrast to multiple dose daily regimens, this mode of base administration is tolerated better and easier to follow. In 17 patients, 7 with the recurrent gravel/colic syndrome and 10 with prior stones, this regimen abolished calculus formation during an average followup of 2 1/2 years. However, further studies are needed before this regimen can be recommended as standard therapy for uric acid stone prophylaxis.- - - - - - - - - - ranking = 0.0027357887858745keywords = calculus (Clic here for more details about this article) |
7/12. CT findings in xanthogranulomatous pyelonephritis with coexistent renocolic fistula.A case of diffuse xanthogranulomatous pyelonephritis of the kidney with an associated renocolic fistula is reported. Computed tomography demonstrated typical findings with an enlarged poorly functioning kidney with multiple near-water-density masses replacing the renal parenchyma surrounding a central staghorn calculus. A mottled gas collection within the renal parenchyma was secondary to a renocolic fistula rather than a pyogenic abscess.- - - - - - - - - - ranking = 0.0027357887858745keywords = calculus (Clic here for more details about this article) |
8/12. Partial dissolution of struvite calculus with oral acetohydroxamic acid.Most staghorn calculi occur in patients who have chronic urinary tract infections with urea-splitting organisms. Acetohydroxamic acid, an inhibitor of the bacterial urease enzyme, is currently undergoing clinical trials to determine whether or not it can prevent stone growth in patients at risk. We report on a patient whose stones grew while she was taking placebo and then decreased in size when she took the active drug.- - - - - - - - - - ranking = 0.010943155143498keywords = calculus (Clic here for more details about this article) |
9/12. renal colic: the role of ultrasound in initial evaluation.A prospective sonographic study of 21 patients with suspected renal colic was undertaken to detect the presence or absence of urinary tract calculi. The presence of calculi was diagnosed sonographically by visualization of the calculus and/or unilateral hydronephrosis in all 18 cases in which presence of a calculus was subsequently proved by surgery, spontaneous passage and recovery, or intravenous urography. In the two cases in which the sonographic examination demonstrated neither calculi nor unilateral obstruction, further evaluation confirmed the absence of calculi. There was one false-positive examination in which unilateral hydronephrosis was detected secondary to a retroperitoneal tumor. There were no false-negative examinations. The results of this study support the use of ultrasound in the initial evaluation of renal colic.- - - - - - - - - - ranking = 0.005471577571749keywords = calculus (Clic here for more details about this article) |
