1/38. 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 = calculus (Clic here for more details about this article) |
2/38. Calyceal diverticula in children: unusual features and complications.Calyceal diverticulum is a relatively rare lesion that is usually asymptomatic but can assume clinical significance if drainage is impaired. Three patients are presented with unusual complications directly referable to a calyceal diverticulum. One child had a mobile calculus. In 2 others, intrarenal inflammatory masses developed in the area previously occupied by a calyceal diverticulum. One of these children had proved xanthogranulomatous pyelonephritis, and the other had an infected diverticulum.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
3/38. patients with renal hypouricemia with exercise-induced acute renal failure and chronic renal dysfunction.We here report the case of a 38-year-old male with back pain and vomiting occurring after exercise. serum creatinine level was elevated, and he was admitted to our hospital with diagnosis of acute renal failure (ARF). He had experienced similar attacks at least 4 times, including the present episode, from the age of 22 years. After admission, the patient was managed only by resting, and remission was nearly attained in about 1 month. The renal biopsy specimen performed on day 15 showed findings of acute tubular necrosis, thickening of the tubular basement membrane, and interstitial fibrosis. After remission, the serum uric acid level was 0.7-0.8 mg/dl, fractional excretion of uric acid was 0.63, and the possibility of other diseases facilitating the excretion of uric acid was denied. Therefore, ARF associated with idiopathic renal hypouricemia was diagnosed. Since only mild responses were observed in a pyradinamide loading test and a benzbromarone loading test, the case was considered to be a presecretary reabsorption disorder type. Renal function tests showed the almost complete recovery of the glomerular filtration rate (GFR: 114 ml/min/1.73 m2), but the urine concentrating ability was markedly decreased (specific gravity 1.019 and osmolarity 516 mOsm/kgxH2O in Fishberg test). Past data from this patient indicated that this renal dysfunction had been persisting for ten years. We examined 9 patients with renal hypouricemia and focused on the differences between the two groups (with or without complications). Four patients had a history of exercise-induced ARF or calculus. The urine concentrating ability was significantly lower in these patients (group A) than in the other patients without complications (group B). The glomerular filtration rate in group A was within the normal range, but was lower than in group B. These results suggested the possibility that patients with renal hypouricemia with complications may have chronic renal dysfunction in the future.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
4/38. A new cause of curvilinear renal calcification: calcified hydrocalycosis.Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomography (CT).- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
5/38. Cutaneous nephrocolonic fistula as a consequence of a kidney stone.We report an unusual case of cutaneous nephrocolonic fistula caused by a renal calculus with perirenal infection. The diagnosis was made by fistulography and computed tomography, after which nephrectomy and resection of the descending colon were successful. We also review the literature on cutaneous nephrocolonic fistulas.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
6/38. Double infundibular obliteration with abscess formation after percutaneous nephrolithotomy.A case of an unusual complication after percutaneous nephrolithotomy. After removal of an infectious staghorn calculus followed by SWL, the patient developed a double infundibular stricture leaving the kidney divided into three separate compartments. In spite of the absence of clinical symptoms of infection, this was further complicated by abscess formation and finally, function loss of the upper part of the kidney. Combined retro- and anterograde endoscopic surgery failed to re-establish the complete continuity of the uretero-caliceal system and the patient had to undergo partial nephrectomy. Possible etiologies, contributing factors and means of prevention for this rare complication are discussed.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
7/38. 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 = 0.5keywords = calculus (Clic here for more details about this article) |
8/38. 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 = 1keywords = calculus (Clic here for more details about this article) |
9/38. Percutaneous management of a nephrocutaneous fistula due to a pyelocaliceal diverticular calculus.Nephrocutaneous fistulas arising from stone-containing pyelocaliceal diverticula are rare. We describe 2 patients who were treated by open drainage for perirenal abscesses. Subsequently, both patients presented with a nephrocutaneous fistula from a stone-containing pyelocaliceal diverticulum. These patients were successfully treated by percutaneous nephrostolithotomy with fulguration of the diverticula.- - - - - - - - - - ranking = 2keywords = calculus (Clic here for more details about this article) |
10/38. Retroperitoneoscopic heminephrectomy of a horseshoe kidney for calculus disease.Retroperitoneoscopic management of complications of a horseshoe kidney provides a feasible and effective alternative to conventional management. We describe a patient who had presented with multiple calculi and a poorly functioning left moiety of a horseshoe kidney, in whom we performed a retroperitoneoscopic left heminephrectomy. Most of the previous reports of laparoscopic nephrectomy have been described via the transperitoneal route. Division of the isthmus was done using ultrasonic shears. The patient had an uneventful recovery and was discharged within 24 hours.- - - - - - - - - - ranking = 2keywords = calculus (Clic here for more details about this article) |
