1/11. Bladder cancer arising in a spina bifida patient.We report the case of a 52-year-old patient with spina bifida, neurologic bladder, and a history of recurrent urinary tract infections (UTIs) in whom a bladder cancer was incidentally discovered. Cytology, cystoscopy, and cystography showed nonspecific, extensive inflammatory lesions. Cystography demonstrated a complex of diverticulae and cellules. Pathologic examination of a diverticulectomy specimen revealed a grade III pT3b transitional and squamous cell carcinoma. Because of the similar disease causation (recurrent UTIs, stones, and indwelling catheterization), we suggest extension of the guidelines proposed for patients with spinal cord injuries (ie, annual serial bladder biopsies) to patients with nontraumatic neurogenic bladder.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
2/11. Technique of laparoscopic nephrectomy in a patient with previous urinary diversion.Laparoscopic nephrectomy is quickly becoming accepted as the standard treatment for small renal neoplasms and benign renal disease. The presence of an ileal conduit has been termed a relative contraindication to laparoscopic surgery. A 58-year old female presented with recurrent pyelonephritis and hydronephrosis of her left kidney. Surgical removal was necessary and we considered a transperitoneal laparoscopic nephrectomy for her. The patient had an ileal conduit and it was because of this reason that only after careful consideration was it decided to attempt the surgery using the laparoscopic approach. We present our technique of transperitoneal laparoscopic nephrectomy in this patient with an ileal conduit and include technical suggestions that will help predict a successful outcome. The success of this case demonstrates that in certain circumstances, patients with urinary diversions can be offered laparoscopic nephrectomy and its benefits.- - - - - - - - - - ranking = 20.819522828391keywords = neoplasm (Clic here for more details about this article) |

4/11. Abdominal pathology in spinal cord injured persons.The assessment and management of abdominal disease in persons with spinal cord injuries is extremely complex. Alterations in the normal conduction of impulses to the brain can result in symptoms that may be quite unlike those which are commonly associated with abdominal pathology. A number of features, however, have been identified which can assist the practitioner in the interpretation of the clinical evaluation. This article discusses those findings and the most commonly occurring abdominal disorders in which they are seen. Two case studies are presented which exemplify the symptomatology described and which reinforce the need for early accurate diagnosis and management of abdominal disease in spinal cord injured persons.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
5/11. Retroperitoneal haemorrhage with abscess formation complicating Waldenstrom's macroglobulinaemia.The complications of bleeding in patients with Waldenstrom's macroglobulinaemia (WM) are relatively well described. The pathophysiology of such a haemorrhagic diathesis is complex and involves the inhibition and depression of coagulation factors as well as qualitative and quantitative platelet abnormalities. Treatment of WM must be targeted at the underlying lymphocellular malignancy, but amelioration of the hyperviscous state and component transfusion(s) to correct abnormal coagulation parameters will decrease the incidence of bleeding. A case of WM with E. coli urinary tract infection and subsequent retroperitoneal haemorrhage with abscess formation and sepsis is presented. The pathophysiology and management of such patients is described.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |

7/11. association of xanthogranulomatous pyelonephritis with small renal cell carcinoma. Case report and review of the literature.A case of xanthogranulomatous pyelonephritis associated with 'small' renal carcinoma is presented. The urinary sediment showed atypical cells, suspect of malignancy. The renal neoplasm measured only 1.5 cm, had the typical papillary configuration of a 'small' renal carcinoma and was composed of atypical cells with finely granular cytoplasm and hyperchromatic nuclei. The xanthogranulomatous pyelonephritis was a primary lesion, spacially separate one from the other. The clinicopathological features of reported examples of coexistence of these diseases have been reviewed.- - - - - - - - - - ranking = 20.819522828391keywords = neoplasm (Clic here for more details about this article) |
8/11. Acute lobar nephronia: a case report.Acute lobar nephronia (ALN), a term analogous to acute lobar pneumonia, refers to a renal mass caused by acute focal infection without liquefaction. An alternative term is acute focal bacterial nephritis (AFBN). fever, flank pain or back pain are the most frequently encountered clinical characteristics. Imaging modalities used to establish a definite diagnosis of acute lobar nephronia included sonography, computed tomography and nuclear medicine. Uroradiographic findings in this condition can mimic a renal abscess or neoplasm. Further distinction between acute lobar nephronia and other renal masses is aided by the appropriate use of renal sonography and computerized tomography is the most effective and least costly method in diagnosis. Serial sonograms can be used to monitor response to antibiotic therapy. Clinical and uroradiographic characteristics of a six year-old female patient with acute lobar nephronia are presented, along with a review of literature.- - - - - - - - - - ranking = 20.819522828391keywords = neoplasm (Clic here for more details about this article) |
9/11. Recurrent and de novo glomerulonephritis postrenal transplantation.Important conceptual advances in recent years have been made in the area of posttransplant GN mainly in the de novo form rather than in recurrent posttransplant glomerulonephritis. Important patient subgroups have been identified for whom a significant risk exists. In particular, those carriers of hepatitis c virus may develop immune-complex renal disease leading to both MGN and MPGN. A de novo form of FSGN may occur in very long-term renal allograft patients. A case cited of an identical twin donor and her recipient developing glomerulosclerosis more than 10 years posttransplant represents an instance where the provocative hyperfiltration hypothesis was not relevant. The possibility that FK 506 may rescue cases of de novo posttransplant HUS11 is exciting and needs further elucidation. Finally, the serious lesions of CyA vasculopathy and those of chronic renal allograft rejection may be ameliorated as experience is gained with newer potent immunosuppressive drugs, such as FK 506 as the UNOS data suggest.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
10/11. Acute pyelonephritis simulating poorly vascularized renal neoplasm. Non-specificity of angiographic criteria.A case of acute pyelonephritis associated with venous encasement and amputation is described. Although venous encasement and amputation have been considered previously as specific signs of malignancy, it is now clear that these signs are non-specific, occurring also in inflammatory diseases of the kidney.- - - - - - - - - - ranking = 83.278091313566keywords = neoplasm (Clic here for more details about this article) |
