11/1001. Diffuse alveolar damage in BCGosis: a rare complication of intravesical bacillus Calmette-Guerin therapy for transitional cell carcinoma.Intravesical administration of bacillus Calmette-Guerin is a relatively simple procedure used in the treatment of superficial transitional cell carcinoma of the urinary bladder. It is usually well tolerated with few major side effects. In rare instances, systemic complications can result in death. The usual autopsy finding is that of caseating and non-caseating granulomata in the affected organ. We report the second case of BCGosis in which granulomata together with acute and organising phase diffuse alveolar damage were found in the lungs.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
12/1001. A sensitive bladder: an atypical presentation of cancer in a U.S. Army pilot.Bladder cancer is the most common cancer in the urinary tract, the vast majority (90%) of which are transitional cell carcinomas. A papilloma (grade I) lesion offers an excellent prognosis after excision, though recurrence is possible. The classic sign of bladder cancer is gross, painless hematuria. We report a case of transitional cell papillary carcinoma in an aircrew member with atypical presentation: irritative voiding symptoms without hematuria. With a careful history and physical, and aggressive clinical suspicion, an early diagnosis was made offering an excellent prognosis. The patient, an Army helicopter pilot, returned to flight status with a waiver.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
13/1001. Neuroblastoma of the urinary bladder, preclinically detected by mass screening.BACKGROUND: Since the introduction of mass screening of infants for neuroblastoma, the incidence of neuroblastoma has increased in japan. The reason for this increased incidence is the possible inclusion of many neuroblastomas that would have regressed spontaneously and would never have been detected clinically. An extremely rare tumor at the dome of the urinary bladder in a 7-month-old infant was detected by the mass screening. methods: A case of neuroblastoma of the urinary bladder is reported with a review of the literature. The data in the japan Children's Cancer Registry are also reviewed to analyze the incidence and the site of origin of neuroblastoma for evaluation of mass screening. RESULTS: A 7-month-old female infant was referred because of a positive urine vanillylmandelic acid screening test. ultrasonography showed a solid mass attached to the urinary bladder. At laparotomy a 35 x 30 x 25-mm egg-shaped tumor was found at the dome of the bladder, and a partial cystectomy was performed. During the operation no changes in blood pressure occurred when the tumor was manipulated. Histologic diagnosis was rosette-fibrillary neuroblastoma originating in the bladder wall, with a favorable Shimada histopathologic classification. N-myc was not amplified, which predicted a favorable prognosis, and no postoperative chemotherapy was given. The patient was free of symptoms and tumor after a follow-up period of 16 months. literature review revealed that this was the second case of neuroblastoma of the urinary bladder ever reported in the world, although several cases of pheochromocytoma originating in the bladder wall had been reported. Both neuroblastoma and pheochromocytoma derive from the neural crest. The sympathogonia from the neural crest, a common stem cell, differentiates into a ganglion cell or into a secretory cell known as a chromaffin cell, able to manufacture catecholamines. The first case in the world that was reported as neuroblastoma of the urinary bladder was in a 4-month-old infant who was noted to have a 4-cm lower abdominal mass on routine physical examination. A ganglioneuroblastoma of the dome of the bladder was excised and the patient was doing well. On reviewing the japan Children's Cancer Registry, the incidence of neuroblastomas in infants has increased as well as the number of stage 1, 2, and 4s (stage 4 special) neuroblastomas since the introduction of mass screening. However, there has been no significant change in the number of stage 3 or 4 diseases diagnosed in older children. According to the japan Children's Cancer Registry, pelvic origin neuroblastoma, which has been noted to have spontaneous regression, was more frequent in the primary tumors detected by mass screening when compared with those presenting clinically. During preparation of this manuscript another case of bladder dome neuroblastoma was detected by urinary vanillylmandelic acid screening of 6-month-old infants for neuroblastoma in japan. CONCLUSION: These extremely rare cases of neuroblastoma of the urinary bladder involved children younger than 1 year of age and were incidentally detected by routine physical examination or mass screening. This raises the question of whether these tumors might have regressed spontaneously had they gone undetected and untreated.- - - - - - - - - - ranking = 11keywords = urinary (Clic here for more details about this article) |
14/1001. A successfully treated case of condyloma acuminatum of the urethra and urinary bladder.Condyloma acuminatum very seldom affects the urinary bladder, but if it does conservative treatment has been considered of little value and cystourethrectomy will eventually be required. A case with urethrovesical condyloma is presented, where repeated transurethral resections cured the patient.- - - - - - - - - - ranking = 5keywords = urinary (Clic here for more details about this article) |
15/1001. neurofibromatosis 1 associated with embryonal rhabdomyosarcoma of the urinary bladder.A 10-month-old boy presented with a 6-week history of abdominal pain. The pain was due to a large, stage IV embryonal rhabdomyosarcoma of the urinary bladder. The rhabdomyosarcoma was found in association with neurofibromatosis 1 (NF1) manifesting multiple cafe au lait spots and bowing of the right calf. The diagnosis of NF1 had not been made before presentation. This case report is intended to heighten the awareness of the manifestations of NF1 and the possibility of developing a nonneuroectodermal tumor as a concomitant of NF1, and to emphasize the importance of timely diagnosis and treatment of such an NF1-associated malignancy. Reports of the epidemiologic evidence for rhabdomyosarcoma in children with NF1 are reviewed.- - - - - - - - - - ranking = 5keywords = urinary (Clic here for more details about this article) |
16/1001. Acute renal failure due to obstruction in burkitt lymphoma.Acute renal failure in burkitt lymphoma is commonly the result of tumor lysis syndrome. We present a 15-year-old boy who developed hypertension, seizures, and acute renal failure due to extrinsic compression of the bladder and ureters by a large retrovesical burkitt lymphoma. The causes of acute renal failure in burkitt lymphoma and the incidence of acute urinary obstruction in this disease are reviewed.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
17/1001. holmium: YAG laser endoureterotomy in the treatment of ureteroenteric strictures following orthotopic urinary diversion.The management of ureteroenteric strictures in patients who have undergone urinary diversion can be challenging. In those patients with an orthotopic neobladder, anastomotic ureteral strictures can be treated endoscopically using a retrograde or antegrade approach. The availability of small (7.5F) flexible ureteroscopes, as well as the use of the holmium laser has facilitated the ability to precisely incise the stricture under direct endoscopic visualization (endoureterotomy). We describe our technique for laser endoureterotomy in patients with ureteroenteric strictures following orthotopic urinary diversion.- - - - - - - - - - ranking = 6keywords = urinary (Clic here for more details about this article) |
18/1001. Intra-abdominal abscess due to patient non-compliance after construction of an ileal neobladder: case report and review of the literature.PURPOSE: A case report of patient with an intra-abdominal abscess 8 weeks after radical cystectomy and construction of an ileal neobladder is presented. methods/RESULTS: The patient was admitted with nausea, vomiting and singultus. A perforation of the neobladder due to overdistension was assumed to be the underlying cause of the intra-abdominal abscess formation as the patient admitted infrequent voiding during the day and no emptying of the neobladder at night. The patient underwent explorative laparotomy and 4200 mL of pus was removed from the abdominal cavity. The patient made an uneventful recovery and was discharged from hospital after 5 weeks. Neobladder function remained stable and the patient was leading a normal life at 24 months follow-up. CONCLUSIONS: The present case demonstrates the need for careful patient selection prior to radical cystectomy with continent urinary diversion. Reduced compliance and mental disabilities of a patient can increase the complication rate.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
19/1001. Granulomatous hepatitis following intravesical bacillus Calmette-Guerin therapy.Although intravesical bacillus Calmette-Guerin (BCG) administration is an effective method in the treatment of superficial urinary bladder carcinoma, some complications may arise such as a granulomatous reaction either in the urinary tract or, in rare cases, outside the urinary tract. We report in this paper a case of granulomatous hepatitis following intravesical BCG administration.- - - - - - - - - - ranking = 3keywords = urinary (Clic here for more details about this article) |
20/1001. Combined small and transitional cell carcinoma of the urinary bladder with CA19-9 production.It is well known that extrapulmonary small cell carcinoma, which exhibits morphological features similar to those observed in the lung, occurs in various organs. Clinically, most cases manifest aggressive biological behavior. A case of small cell carcinoma of the urinary bladder producing a high level of serum carbohydrate antigen (CA) 19-9, in which expression was confirmed in cancer cells of small as well as transitional cell carcinoma in the same tumor mass by immunostaining is reported. This paper documents combined small and transitional cell carcinoma of the urinary bladder with CA19-9 production, although it has already been reported that adenocarcinoma or transitional cell carcinoma in various organs frequently expresses CA19-9. Observations suggest that the histogenesis of some cases of combined small and transitional cell carcinoma in the urinary bladder may be the same, as both can produce CA19-9.- - - - - - - - - - ranking = 7keywords = urinary (Clic here for more details about this article) |
