1/10. Interstitial cystitis and ileus in pediatric-onset systemic lupus erythematosus.A girl aged 11 years presented with autoimmune hemolytic anemia with thrombocytopenia, and subsequently developed severe abdominal pain, vomiting, and pollakiuria. X-ray findings of her abdomen demonstrated paralytic ileus with intestinal wall thickening. Intravenous pyelography revealed bilateral hydroureter with mild hydronephrosis and contracted bladder. Pathological examination of her bladder revealed interstitial cystitis, with evidence of focal deposition of IgG and C3 in a granular pattern on small blood vessel walls. She was diagnosed as having systemic lupus erythematosus (SLE) associated with paralytic ileus and chronic interstitial cystitis. Although initiation of high-dose prednisolone therapy resulted in a gradual improvement in clinical symptoms, reducing the dosage of prednisolone caused a relapse. To our knowledge, the combination of paralytic ileus and chronic interstitial cystitis is quite uncommon in pediatric-onset SLE.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/10. Primary localized amyloidosis of the urinary bladder. A case report.We present case 96 (the first one in bulgaria) of primary localized amyloidosis of the urinary bladder in a 72-year-old woman with episodes of painless hematuria. The amyloid tumor is situated on the anterior wall of the bladder--a yellowish prominence 15 mm in diameter with superficial erosion that is surrounded by a reddish ring and bullous edema of the mucosa. Rough and regularly pink perivascular deposits, thickened vessel walls and focal lymphoplasmocyte infiltrates are present in the submucosa. After preliminary treatment with KHMnO4, AL-amyloid is detected in polarized light by Congorot staining and in ultraviolet light using thioflavin. immunoglobulins and C3 deposits are not found. On electron microscopy deposits of amyloid fibrils are seen in abundance close to collagen bundles. Diseases that may be associated with systemic amyloidosis have been clinically excluded. Nodular amyloidosis resulting from a local immune dyscrasia is accepted in the case. The patient is in good health 11 months after the first biopsy. A literature review on this rare form of localized amyloidosis has been made. Generally, the disease has a favorable prognosis and non-active behavior is recommended. Intravesical instillations of dimethyl sulfoxide, sectional resection or plastic surgery that preserve the urinary tract are used in the rare case of progressive course.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/10. Superselective embolization of bladder arteries in the treatment of intractable bladder haemorrhage.Bladder hemorrhage following radiation therapy is a serious complication in patients undergoing this treatment. Several methods have been proposed to control this particular situation; however, results have been far from satisfactory, with the exception of drastic measures such as hypogastric artery ligation and radical cystectomy. We recently used a method of superselective embolization of the bladder arteries which enabled us to control severe intractable bleeding in a patient submitted to bladder irradiation for a transitional cell infiltrating carcinoma. Compared to selective embolization and other methods, the advantages of superselective embolization are a lower recurrence rate concerning bleeding, fewer side-effects and the possibility of using adaptable embospheres (150-1000 micron) which, on account of their marked plasticity, offer better occlusion of the vessels. For these reasons, superselective embolization of the bladder arteries should be considered as the treatment of choice in intractable bladder hemorrhage.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/10. placenta percreta invading the bladder: report of 2 cases.We report 2 cases of placenta percreta with invasion of the bladder that resulted in massive hemorrhage at cesarean section. Control was achieved by hysterectomy, bilateral internal iliac artery ligation, suture ligation of bleeding vessels and bladder repair, with no fetal or maternal mortality.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/10. Huge pelvic fibromatosis encroaching on the urinary bladder. A case report.A patient with a huge pelvic fibromatosis, a form of intra-abdominal desmoid, encroaching on the urinary bladder is described. Because of its rarity, there is frequently a lack of diagnostic awareness of this tumor, particularly in the gynecological or urological patient. Although this tumor is a locally invasive benign tumor which dose not metastasize, management by radical tumor excision without the sacrifice of the major pelvic nerves and vessels is mandatory, since this tumor has generally a high postsurgical recurrence rate.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/10. Primary localized amyloidosis of urinary bladder.Primary localized amyloidosis of the bladder is rare. Two new cases are presented, and 44 cases from the literature are reviewed. The disease tends to occur in a younger age group in men than in women. It presents most frequently with gross painless hematuria, and usually appears at cystoscopy as a tumefied, yellowish, and occasionally ulcerated lesion. The amyloid deposits usually involve suburothelial connective tissue, suburothelial vessels, and less markedly the vesical muscularis. The treatment varies from transurethral resection to total cystectomy with urinary diversion. Transurethral resection appears to be the treatment of choice, if feasible. Close follow-up of the patient is necessary because of the frequency of multiple recurrences, which may require an ablative procedure.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/10. Selective embolization of the vesical artery in the management of massive bladder hemorrhage.Massive bladder hemorrhage was sucessfully treated by selective embolization of the unilateral vesical artery in two patients with vesical neoplasms. In one patient, complete hemostasis was obtained by partial occlusion of the unilateral vesical artery, although the lesion had another feeding vessel from the contralateral artery. This method is simple and effective in controlling massive bladder hemorrhage, as it has the advantages of minimizing ischemic pain, preventing the hazards due to extensive infarction and reflux of embolic material, and reducing tumor bulk.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/10. Steroid pulse therapy in lupus cystitis.A middle-aged woman with lupus cystitis showed no other symptoms of lupus vasculitis. Cystoscopic findings revealed mucosal hemorrhage and hyperemia. Histological studies of the bladder showed mucosal edema, inflammatory cellular infiltration and the deposition of immune complexes along the vessels. She was treated with a combination of intravenous methylprednisolone pulse therapy and oral prednisolone. cystoscopy and histological findings showed appreciable improvement. Elevated urinary levels of chemokines such as interleukin-8 (IL-8) and monocyte chemotactic and activating factor (MCAF) decreased during convalescence. These results suggest that the early diagnosis and treatment with steroid pulse therapy achieves improvement of an unusual vasculitis symptom, lupus cystitis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/10. Urologic abnormalities in Menkes' kinky hair disease: report of three cases.Menkes' kinky hair disease is a rare congenital disorder of copper metabolism with X-linked recessive inheritance. It is well known that it is frequently associated with urologic abnormalities. The authors experienced three such cases, but each of them was different. Multiple bladder diverticula, right vesico-ureteral reflux, and right hydronephrosis were noted on the first baby boy. In the second case, hematomas in the left kidney, pelvis, ureter and the adipose capsule, which were thought to be the abnormality of vessels, were noted in the neonatal period. In the third body, multiple bladder diverticular were noted at the age of 1 year. One year, 10 months later, a spontaneous rupture at the huge diverticulum occurred.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/10. Two cases of vasculitis of the urinary bladder: diagnostic and pathogenetic considerations.BACKGROUND: Vasculitis involving the urinary bladder is rare and difficult to diagnose. Organ-isolated vasculitis challenges pathogenetic theories. methods AND RESULTS: A human immunodeficiency virus- and hepatitis b virus-infected man with hematuria and a mass lesion was initially given a clinicopathologic diagnosis of bladder hamartoma. Over 11 months, without immunosuppressive therapy, there were multiple "recurrences" of the tumor with progressive distal ureteral obstruction, but no evidence of systemic vasculitis. polyarteritis nodosa-like vasculitis with positive immunostaining for hepatitis B surface antigen in urothelium and vessels was found on review. A second patient, presenting with signs and symptoms suggesting transitional cell carcinoma in situ, was found to have small vessel vasculitis. CONCLUSIONS: Bladder vasculitis should be considered in the differential diagnosis of neoplasia. Extrahepatic hepatitis b virus infection may be related to the organ specificity in some cases of vasculitis.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
