1/14. 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 = 1keywords = calculus (Clic here for more details about this article) |
2/14. 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 = 1keywords = calculus (Clic here for more details about this article) |
3/14. klebsiella pneumoniae urinary tract infection complicated by endophthalmitis, perinephric abscess, and ecthyma gangrenosum.We have reported the case of an immunocompromised patient with a K pneumoniae bacteremia admitted with endophthalmitis. The source of the infection was an asymptomatic left renal calculus associated with a perinephric abscess. Persistent bacteremia resulted in the development of ecthyma gangrenosum, which has not previously been associated with Klebsiella spp infection.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
4/14. Percutaneous removal of "extra-renal" residual urinary calculus.We report a case of an "extra-renal" calculus and associated perinephric abscess treated by endourologic techniques. The calculus could have fallen into the perinephric tissues at the time of open renal surgery.- - - - - - - - - - ranking = 6keywords = calculus (Clic here for more details about this article) |
5/14. Diagnostic ultrasound: its value in acute urinary tract infection in spinal cord injury.Two cases of acute urinary tract infection in patients with spinal cord injury highlight the complications of calculus and perinephric abscess. Rather than waiting the customary 48 hours to assess response to antibiotics before evaluation for secondary complications, diagnostic ultrasound is advocated upon diagnosis of pyelonephritis. The potential benefits of early imaging seem to far outweigh the negligible risk and expense.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
6/14. 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 = 1keywords = calculus (Clic here for more details about this article) |
7/14. Calculocutaneous sinus.Extrusion of a urinary calculus is a rare occurrence, and to date only 7 cases have been previously documented. Three patients are described, all of whom had a persistent discharging calculocutaneous sinus as a manifestation of the extruded calculus. The 3 cases had similar features of presentation with a perinephric abscess, a staghorn calculus within a nonfunctioning kidney, and a classic radiologic feature of a portion of calculus clearly distinct from the main bulk of the stone.- - - - - - - - - - ranking = 4keywords = calculus (Clic here for more details about this article) |
8/14. Recurrent psoas abscess.recurrence of a psoas abscess in exactly the same location is very unusual--in fact, we found no other reports in the literature. laparotomy performed after the patient presented with the second abscess revealed an impacted calculus and diverticulitis of the appendix as the cause. Computed tomography was effective in establishing the diagnosis, but the question of the best method of treatment remains. Percutaneous drainage was insufficient in this case.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
9/14. CT demonstration of spontaneous extrusion of staghorn calculus.We report a patient in whom spontaneous extrusion of a staghorn calculus into the flank soft tissues was diagnosed by CT. The stone was demonstrable on CT as fragments of calcific density appearing in the subcutaneous area. To our knowledge this complication of renal calculus disease has not been previously reported.- - - - - - - - - - ranking = 6keywords = calculus (Clic here for more details about this article) |
10/14. Computed tomography of perirenal and pararenal inflammatory disease complicating renal calculi.In the presence of unsuspected extensive perirenal and pararenal disease, renal calculus surgery may be associated with extensive morbidity and mortality. To plan surgery properly, computed tomography (CT) often can be essential preoperatively. Three cases are presented where CT readily demonstrated the degree of extrarenal extension. No other imaging modality can demonstrate this involvement as accurately and as easily.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
