12/253. Abdominal aortic aneurysm with aorta-left renal vein fistula with left varicocele.Abdominal aortic aneurysm with spontaneous aorto-left renal vein fistula is a rare but well-described clinical entity usually with abdominal pain, hematuria, and a nonfunctioning left kidney. This report describes a 44-year-old man with left-sided groin pain and varicocele who was treated with conservative measures only. The diagnosis was eventually made when he returned with microscopic hematuria, elevated serum creatinine level, and nonfunction of the left kidney; computed tomography scan demonstrated a 6-cm abdominal aortic aneurysm, a retroaortic left renal vein, and an enlargement of the left kidney. This patient represents the youngest to be reported with aorto-left renal vein fistula and the second case with a left-sided varicocele.- - - - - - - - - - ranking = 0.23585204937213keywords = fistula (Clic here for more details about this article) |
13/253. Ureterorectal fistula: a rare cause of recurrent bacteriuria.The differential diagnosis of recurrent bacteriuria includes a host of conditions very familiar to urologists. Ureterorectal fistula represents an unusual clinical entity that can cause recurrent bacteriuria. We present a patient who ultimately proved to have such a fistula. We review the available literature and comment on the significance of this condition.- - - - - - - - - - ranking = 0.23585204937213keywords = fistula (Clic here for more details about this article) |
14/253. A case of metastatic malignant melanoma presenting with hematuria.We report a case of metastatic malignant melanoma that presented with macroscopic hematuria and lower urinary tract symptoms. Effective palliation of urinary tract symptoms was achieved with transurethral resection of metastatic lesions in the bladder. However, the patient was lost due to widespread disease despite systemic therapy. Solitary or multiple dark blue-black nodular or vegetating lesions encountered during cystoscopy should raise the suspicion of metastasis of malignant melanoma and be investigated accordingly.- - - - - - - - - - ranking = 0.33333333333333keywords = urinary (Clic here for more details about this article) |
15/253. Small cell carcinoma of the bladder. Two cases diagnosed by urinary cytology.BACKGROUND: Primary small cell carcinoma (SCC) of the bladder is a rare but important entity. We report two cases of SCC of the bladder diagnosed by urinary cytology. CASES: A 71-year-old male (case 1) and a 79-year-old female (case 2) presented with asymptomatic gross hematuria. Urinary cytology in case 1 showed the presence of a few undifferentiated malignant small cells and many transitional cell carcinoma (TCC) cells with a bloody and necrotic background. The former cells were small and round, with naked, hyperchromatic nuclei and finely granular chromatin. Pathologic diagnosis after total cystectomy was TCC > SCC > adenocarcinoma, T2M0N0. Urinary cytology of case 2 showed the presence of many undifferentiated malignant small cells and many TCC cells with or without squamous metaplasia. Cytologic features of the former cells were almost the same as those in case 1. Moreover, these cells were neuroendocrine marker positive by immunocytochemistry. Pathologic diagnosis after tumor resection was SCC and TCC > squamous cell carcinoma, T1b. CONCLUSION: The prognosis of primary SCC of the bladder is usually poor. Because our cases were found by urinary cytology at a relatively early stage, both have been well, without any evidence of recurrence, 30 and 25 months after surgery even without adjuvant therapy.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
16/253. radiation-induced pseudocarcinomatous proliferations of the urinary bladder: a report of 4 cases.Four cases of radiation cystitis that caused diagnostic difficulty because of an epithelial proliferation with architectural complexity and reactive cytologic atypia are described. The patients, 2 male, 2 female, were from 43 to 77 years of age. Two presented with hematuria. cystoscopy disclosed abnormalities in 3 patients. Microscopic examination showed irregularly shaped and arranged aggregates of epithelial cells in the upper and mid zones of the lamina propria. The cells, which typically showed at least mild, and sometimes severe, pleomorphism, were usually transitional, but squamous differentiation was seen focally in 3 cases. Ulceration of the overlying epithelium was present in all cases and was prominent and associated with conspicuous fibrin and hemorrhage in one of them. edema of the lamina propria was present in 3 cases, whereas lamina propria fibrosis and chronic inflammation were present in all cases. The presence in all 4 cases of vascular ectasia and other changes characteristic of radiation injury, such as atypical fibroblasts, prompted investigation of the clinical history in 2 cases in which the pathologist was unaware that the patient had received radiation. Pseudocarcinomatous proliferations in the bladder caused by radiation injury have received limited attention in the literature. Our cases illustrate the potential diagnostic errors with which these lesions may be associated.- - - - - - - - - - ranking = 0.66666666666667keywords = urinary (Clic here for more details about this article) |
17/253. Endoscopic injection sclerotherapy control of intractable hematuria following radiation-induced hemorrhagic cystitis. A novel approach.OBJECTIVE: To establish the utility of endoscopic sclerotherapy using 1% ethoxysclerol for the control of intractable hematuria following post-irradiation telangiectatic cystitis (PTC). methods: Our experience of treating 4 patients (one female and three male) with massive exsanguinating hematuria resulting from PTC, using a combined intralesional and perilesional injection of 1% ethoxysclerol, is presented. observation on the distribution, grading of telangiectasis and pattern of bleeding are made. RESULTS: A dramatic and lasting cessation of the hematuria in all the 4 patients was achieved during the follow-up period varying from 1 month to 4 years. CONCLUSION: Endoscopic injection sclerotherapy is a simple, highly effective, less invasive new technique in the management of massive and intractable hematuria due to radiation-induced telangiectasia of the urinary bladder.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
18/253. Tumoral cystitis in children.Three children aged 3-11 years had ultrasonography of the urinary tract for the investigation of dysuria and haematuria. A bladder mass was seen in these 3 children. One child had computed tomography scan, cystoscopy and bladder biopsy because rhabdomyosarcoma was considered. The biopsy revealed an inflammatory process. The urine culture of the other 2 children revealed E. coli. On ultrasonography, the inflammatory mass may appear homogeneously hypoechoic or may contain moderate level echoes. The mucosal surface of the mass may be smooth or lobulated. It is important to consider an infective cause for a bladder mass in children because computed tomography, cystoscopy and biopsy may be avoided.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
19/253. pheochromocytoma of the urinary bladder presenting only with macroscopic hematuria.pheochromocytoma of the bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We describe a case of bladder pheochromocytoma in a 42-year-old female in which macroscopic hematuria was the only alarming symptom. The diagnostic and operative issues of this type of tumor are discussed, along with the challenging treatment option of transurethral resection. diagnosis, treatment and follow-up trends of this rare tumor are reviewed.- - - - - - - - - - ranking = 0.66666666666667keywords = urinary (Clic here for more details about this article) |
20/253. Inverted papilloma as a cause of high-grade ureteral obstruction.Inverted papilloma of the urinary tract is a rare benign lesion. We report, to our knowledge, the first case of high-grade ureteral obstruction caused by an inverted papilloma with coexistent carcinomatous elements. Our patient was referred for evaluation of painless, gross hematuria. Imaging studies demonstrated a left proximal ureteral filling defect causing severe left-sided hydroureteronephrosis. ureteroscopy demonstrated a 1-cm papillary lesion on the medial aspect of the proximal ureteral wall. Pathologic examination documented a lesion with elements of inverted papilloma and a small focus of well-differentiated transitional cell carcinoma. We discuss the management and significance of this rare urothelial lesion.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
