We report here the first case of localized amyloidosis of the ureter and bladder to be treated effectively by occlusive dressing technique therapy using dimethyl sulfoxide. The patient was a 48-year-old woman whose chief complaint was macrohematuria and right back pain. Ultrasound sonography demonstrated right hydronephrosis and an intravesical mass in the region of the right ureteral orifice. Retrograde pyelography revealed severe stricture of the right lower ureter. Cystoscopy demonstrated a yellow submucosal tumor around the right ureteral orifice. We suspected urinary tract amyloidosis, and transurethral biopsy and resection of the intravesical mass were performed under right ureteral stenting. Histopathological diagnosis was amyloidosis. There was no evidence of systemic amyloidosis. To treat residual amyloidosis of the ureter and bladder, we performed occlusive dressing technique therapy using dimethyl sulfoxide every day. After 6 months of therapy, the right hydronephrosis disappeared, and there was no evidence of a recurrence of amyloidosis. We concluded that this therapy was very effective and safe for urinary tract amyloidosis. 相似文献

Amyloidosis is characterized by extracellular deposition of abnormal insoluble fibrils, which cause structural and functional disorders. Amyloidosis is classified into systemic and localized amyloidosis. Localized amyloidosis in individual organs is uncommon. We report a rare case of localized form of primary amyloidosis of the urinary bladder. A 76-year-old male visited our hospital with a complaint of macroscopic hematuria. Cystoscopy showed submucosal hematoma in the anterior wall and broad-based mass occupying the trigone without normal mucosa covered by calcification. Transurethral biopsy and resection were performed. Histopathological diagnosis was AL type amyloidosis occupying submucosal extracellular space. We gave the patient occlusive dressing with dimethyl sulfoxide. In 12 months, cystoscopy and magnetic resonance imaging revealed improvement of the mass-like lesion in the bladder wall. 相似文献

A case of localized amyloidosis of the urinary bladder is reported. A 82-year-old woman visited our hospital with the chief complaint of miction pain and residual urine sensation. Cystoscopic examination revealed a broad-based and nonpapillary tumor without bleeding on the right lateral wall. A transurethral biopsy of this tumor was performed. A histopathological examination with H.E. and Congo red stains demonstrated amyloid deposition in the submucosal layers of the vesical wall. Rectal biopsy and other findings suggested no deposition of amyloid in other organs. On the basis of these findings, we made a diagnosis of localized amyloidosis of the urinary bladder. To the best of our knowledge, the present case is the 23rd of localized amyloidosis of urinary bladder in Japan. The patient was asymptomatic after biopsy. We discuss the clinical features and management of this disease. 相似文献

We report a case of primary localized amyloidosis of the bladder with amyloid deposits which was characterized as being of immunoglobulin light chain origin (AL) including lambda type (A lambda) and P component (AP) using the KMnO4 pretreatment method and immunohistochemical procedures. The patient was treated successfully with intravesical dimethyl sulfoxide instillation and oral administration of high-dose cepharanthin after transurethral resection. Combination therapy with dimethyl sulfoxide and cepharanthin was shown to be useful for primary localized amyloidosis of the bladder. 相似文献

Primary localized amyloidosis of the bladder: experience with dimethyl sulfoxide therapy 总被引:2,自引:0,他引:2
PURPOSE: We present our long-term experience with intravesical dimethyl sulfoxide (DMSO) for primary localized amyloidosis of the bladder. MATERIALS AND METHODS: The study included 4 males and 2 females 28 to 68 years old (mean age 54) at diagnosis of biopsy proven primary localized amyloidosis involving the bladder diffusely or extensively in 1 locale. All patients had normal upper urinary tracts. They continued to be symptomatic (hematuria in 3, irritative voiding symptoms in 1, and hematuria and irritative voiding symptoms in 2) despite conventional transurethral destructive therapy. Every 2 weeks they received 30-minute instillations of 50 ml. 50% DMSO intravesically for 3 months (patient 1), 6 months (1) and 1 year (4). RESULTS: Therapy failed at 3 and 6 months in 2 patients of whom 1 with a contracted bladder underwent cystectomy and another was stabilized for 1 year with laser therapy. In the remaining 4 patients who were followed for 6 years disease stabilized for 2 to 6 years (mean 3.5) but 3 later required additional therapy including repeat DMSO in 1 and laser therapy in 2. CONCLUSIONS: Diffuse or locally extensive bladder involvement by primary localized amyloidosis usually fails to respond to conventional transurethral destructive surgical procedures. Collectively, our experience and the literature suggest that intravesical DMSO can be a bladder saving measure and help resolve ureterovesical obstruction in some patients. High recurrence rate mandates lifelong cystoscopic surveillance. 相似文献

Calcium deposition in the skin, known as calcinosis cutis, is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin. We report a case of idiopathic calcinosis cutis in fingertip treated with surgical excision followed by the occlusive dressing using aluminum foil, and obtained significant pain relief and round-shaped fingertip which looked normal. 相似文献

A 58-year-old woman was introduced to our department complaining of lower abdominal pain and macrohematuria in March, 1978. Intravenous pyelography revealed stenosis and a ureteral stone on the right distal ureter. In May, 1983, she visited our department again. Endoscopically, bleeding from the right ureteral orifice was observed. Retrograde pyelography demonstrated the right hydronephrosis and irregular margin of the right lower ureter. However, the urine cytology was negative, and CT scan and ureteroscopy showed no tumorous lesion on the portion. On 7 August, 1989, partial ureterectomy and end to end anastomosis was performed. Histopathological examination by H-E and Congo red stain proved amyloid deposition. Postoperative course was uneventful. A total of 40 cases of amyloidosis of the ureter in the world are reviewed. 相似文献

A 46-year-old female was referred to our hospital with a complaint of left flank pain. Ultrasongraphy and computed tomography demonstrated a left hydronephroureter due to stenosis with a ureteral mass in the left lower ureter. Retrograde pyelography revealed severe stricture of left lower ureter and brushing cytology showed papanicolaou class III. Ureteral tumor was suspected and left nephroureterectomy with partial cystectomy was performed. Histopathological diagnosis was amyloidosis of the left ureter. There was no evidence of secondary or systemic amyloidosis. Finally, we diagnosed her with localized amyloidosis of the left ureter. Localized amyloidosis of the ureter is a relatively rare condition, and this is the 55th case reported in the Japanese literature. 相似文献

In the two cases we report here, tumors were diagnosed as nephrogenic adenoma by pathohistological examination. Case 1 was a 72-year-old female presenting with a bladder tumor 8 months after receiving ureteral tumor surgery. Transurethral resection of bladder tumor (TUR-Bt) was performed. Case 2 was a 57-year-old female who had received intravesical bacillus Calmette-Guérin (BCG) treatment 6 times after her fifth TUR-Bt. Two tumors were found by cystoscopy, and TUR-Bt was performed. There have been 39 cases of nephrogenic adenoma of the bladder reported in Japan; 21 were male and 18 female with a mean age of 56.5 years. The main complaint was hematuria, which was seen in 16 cases followed by pollakisuria in 6 cases. Nephrogenic adenoma occurred after surgery of the urinary tract in 16 cases, followed by urinary tract infection in 9 cases and intravesical BCG treatment in 6 cases. The ratio of cases occurring after intravesical BCG treatment has increased since BCG approval for bladder carcinoma treatment in December 1996 in Japan, and an increase in the number of cases is expected in the future. 相似文献

We report two cases of symptomatic prostatic cysts, which were arising around the bladder neck, in a 39-year-old man without clinical evidence of benign prostatic hyperplasia and a 72-year-old man with refractory bladder outlet obstruction. The lesions were found by abdominal ultrasound examination for post-voiding residual at the first visit. Transurethral unroofing of the cysts was performed with successful resolution of voiding symptoms. 相似文献

A case of primary amyloidosis of the ureter is presented. The patient was a 48-year-old woman with a 5-year history of asymptomatic macrohematuria. Roentgenographic examination showed left hydronephrosis and stenosis of the left distal ureter. Histological examination of the biopsied specimen during the operation revealed no malignancy; and, left partial ureterectomy and uretero- vesiconeostomy was performed. Congo red stain proved amyloid deposition after surgery. Rectal biopsy was negative for amyloid; and, other laboratory findings were within normal range. Thus it was diagnosed as a primary localized amyloidosis of the ureter. Importance of intraoperative histologic examination was discussed. This is the 22nd case in the literature. 相似文献

Primary amyloidosis of the seminal vesicle is a rare disease entity. We report here a case of localized seminal vesicle amyloidosis with hematospermia. A 66-year-old man visited our hospital with a chief complaint of hematospermia. T2 weighted magnetic resonance imaging (MRI) showed a hypointensity mass in the left seminal vesicle. Needle biopsy revealed amyloidosis of the seminal vesicle. Without any specific treatment, the mass lesion disappeared on MRI, and hematospermia was improved. 相似文献

A case of primary amyloidosis of the bladder, which developed 4 years after primary treatment, is described. The patient is a 55-year-old male, who consulted our clinic with a complaint of asymptomatic gross hematuria on October 1, 1983. Cystoscopic examination showed a tumorous lesion involving right lateral wall of the bladder, which was resected transurethrally. No malignancy was found by histopathological examination. About 4 years later, he consulted our clinic again with a complaint of asymptomatic gross hematuria. There was a tumorous lesion involving left lateral wall of the bladder on cystoscopy. Transurethral resection of bladder tumor was performed under a diagnosis of bladder tumor. Histological examination revealed amyloidosis of the bladder, AL-type amyloid. Re-examination of the specimens resected 4 years ago showed the same findings. Biopsies from the tongue, skin and rectum disclosed no amyloid deposition. During these 19 months, he had no recurrence. This case was thought to be the first one of primary amyloidosis of the bladder showing new recurrence reported in Japanese literature. 相似文献
