We report a case of malacoplakia in the ureter and bladder. A 78-year-old woman was admitted to our department for detailed examination of hydronephrosis. A small-fingertip-sized tumorous yellowish white lesion was detected by cytoscopy at a site that appeared to be the right side of the ureteral orifice. Transurethral resection was performed on the same site. Flat yellowish white protruding lesions were seen at two sites on the right ureter. Michaelis-Gutmann bodies were observed in biopsy specimens from both the bladder and ureter, and a diagnosis of malacoplakia was made. Ascorbic acid and bethanechol chloride were administered postoperatively. Endoscopy performed three months after the operation showed that the protruding lesions in the bladder and ureter had disappeared. Narrowing of the ureter or vesicoureteral reflux has not been seen to date. 相似文献

Ureteral involvement due to Crohn's disease occurs in 3% to 6% of cases. Herein, we present a case of a 22-year-old woman with ileocolic Crohn's disease with right hydronephrosis due to compression of the ureter that was resolved with a 3-stage, minimally invasive procedure (preoperative percutaneous nephrostomy, ureteral stent placement, and sequential laparoscopically assisted ileocolectomy). Percutaneous right nephrostomy drainage permitted us to prevent renal damage before surgery, and successive ureteral double-J catheter placement minimized the risk of ureteral damage during the laparoscopic procedure. The safety and feasibility of sequential minimally invasive management of ileocolonic Crohn's disease involving the right ureter was assessed, and a good cosmetic result was achieved. 相似文献

A 46-year-old man was admitted to our hospital complaining of macroscopic hematuria with dull pain in the right flank. Laboratory finding showed renal dysfunction and abdominal ultrasound sonograph revealed bilateral hydronephrosis (right > left). Retrograde pyelography showed left ureteral calculi and a filling defect in the middle portion of the right ureter. Renal function improved after bilateral single-J ureteral stent placement. Selective wash cytology of right renal pelvis was class II. Ureteroscopy demonstrated right ureteral obstruction with smooth-surfaced protruded tumor and cold cup biopsy was performed. Histopathological diagnosis was a fibroepithelial polyp but with no malignancy. In addition, left transurethral lithotripsy was performed under ureteroscopy. After the endoscopic examination, a double pigtail stent inserted into the right ureter. We performed conservative management by repeat urine cytologies and retrograde pyelography due to thrombocytopenia. The urine cytologies all proved negative and retrograde pyelography showed no abnormal changes. A ureteroscopic procedure is considered to be useful for the diagnosis of ureteral polyps. Transurethral resection of ureteral polyps with a ureteroscope is recommended for treatment. 相似文献

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

A 62-year-old man was admitted to our hospital with complaints of abdominal pain and rectal bleeding. Although the colonoscopic examination was highly suggestive of a carcinoma, the histopathological examinations were consistent with chronic inflammation. CT examination revealed a solid lesion from cecum to the ascending colon with right urethral invasion. Percutaneous right nephrostomy was performed for grade 2-3 hydronephrosis. Three days after hospitalization, ileus developed and right hemicolectomy was performed. During surgery we observed that the lesion had invaded the middle part of ureter. So the middle part of ureter was removed with side-to-side urethral anastomosis and 6F double-J catheter was placed. The histopathological findings of resected specimen were consistent with ameboma. Reviewing the literature unilateral hydronephrosis due to colonic amebiasis has not been reported. 相似文献

A case of ureteral and vesical malacoplakia is reported. A 58-year-old woman was admitted for non-papillary sessile bladder tumor. Ultrasound examination revealed bilateral hydronephrosis and renal function was deteriorated. Escherichia coli and beta-streptococcus were isolated from her urine. Antegrade pyelography demonstrated obstruction of the bilateral ureters. Percutaneous pyeloscopy revealed a bean-sized yellow nodule at the upper portion of the right ureter. Pathohistological the lesions of aggregates of macrophage in which typical Michaelis-Gutmann bodies were found at the punch biopsies of both vesical and ureteral lesions. She was treated successfully with the administration of bethanechol chloride and antibiotics. This case seems to be the second report of ureteral malacoplakia in the Japanese literature. 相似文献

A case of ureteral complication observed after endopyelotomy is reported. A 19-year-old female patient suffering from right hydronephrosis due to uretero pelvic junction stenosis was treated with endopyelotomy. The stenotic ureter was incised by cold knife for a distance of 5 cm through full thickness. The cut ureteral segment was intubated with a ureteral stent catheter of 10 Fr calibre. The top of the catheter was advanced 1 cm from the edge of the incised ureter. To prevent protrusion of the catheter tip, a flexible guide wire 0.038 inches in diameter was inserted into the catheter and the tip of the guide wire was advanced to the bladder. Antegrade pyelography performed 3 weeks after the operation revealed a lesion resembling a pseudo-ureter. It was made by the catheter that had slipped out of the incised ureter. The lumen of the true ureter was also preserved without stenosis. After removal of the stent catheter and safety guide wire, the true ureter was intubated with a double J catheter of 10 Fr calibre. One week later the pseudo-ureter was not demonstrated by excretory urography performed. Finally, hydronephrosis due to uretero pelvic junction stenosis was treated successfully. 相似文献

A case of retroperitoneal xanthogranuloma is reported. A 51-year-old man was referred to our hospital for the evaluation and treatment of right flank pain and hydronephrosis. Intravenous urography (DIP) and retrograde pyelography revealed the stricture in the middle portion of the right ureter. Ureteroscopy revealed no mucosal lesions. Computed tomography revealed the paraureteric mass lesion. Partial ureterectomy, mass resection and uretero-ureterostomy were performed. Then a double J stent was left in place for 6 weeks. The stricture was due to a yellowish mass adhered to the right side of the ureter. The resected mass measured 1.0 x 2.0 x 1.0 cm. The histopathological diagnosis was xanthogranuloma. The patient is in good health without recurrence 4 months after the surgery. 相似文献

We have experimentally produced a ureteral stent which prevents vesicorenal reflux. This stent has a thin silicon sleeve at its distal end (intravesical portion). In a model experiment the sleeve demonstrated an excellent capability to prevent reflux. The sleeve allowed flow of fluid with minimal pressure rise. A patient with bilateral ureteral obstruction was managed with endoscopic insertion of a sleeved stent in the right ureter and a usual pigtail stent in left ureter. During cystography vesicorenal reflux was not observed on the right side while reflux occurred on the left side. Excretory urography forty days after stent placement demonstrated recovery of renal function and maintenance of drainage in both renal units. Thus, the drainage characteristic of this stent appears to be approximately the same as that of usual stent. 相似文献

Malacoplakia of the urinary tract affects primarily the bladder and secondarily the distal ureter. Characteristic gross and microscopic lesions have been well described. A case of malacoplakia is reported in a 55-year-old woman who presented with hydronephrosis in a solitary kidney. The only lesion in the urinary tract was an apple-core type mass of the distal ureter, which was resected. This represents a rare and unusual presentation of malacoplakia. The differential diagnosis and pertinent literature are discussed. 相似文献

In this study we describe 22 cases of retrograde ureteral stent placement in pregnant women with therapy-resistant flank pain
due to hydronephrosis. Eleven were primiparous and one patient expected twins. Eight of 22 patients presented symptoms of
pyelonephritis. In 21 cases the hydronephrosis was located on the right and in 4 cases it was bilateral. Maximal lower calix
diameter was 12 mm (range 9–22 mm). With the exception of two cases, sonographically controlled stent placement was performed
under local anesthesia without sedation. All patients were painfree within 6 days and were given prophylactic low dosis of
antibiotic until the day of delivery. Renal function remained within the normal limits. Double-J stent displacement occured
in 3 patients – of which one underwent nephrostomy. Postnatal examination demonstrated urolithiasis in 4 of 19 patients. This
study provides evidence for effectiveness of retrograde ureteral Double-J stent placement as a therapeutic option in cases
of severe symptomatic hydronephrosis during pregnancy with a low morbidity rate. 相似文献

A 48-year-old female was found to have right flank pain at another hospital and transabdominal ultrasonography showed right hydronephrosis. She was referred to our department for further examination. She had undergone right oophorectomy and total hysterectomy 3 years before. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at the lower portion of the right ureter. Endometriosis had developed at the site of previous surgery on the appendix. A mass was formed in an extensive area including the endometriotic lesion, due to adhesion following previous surgery or other reasons, and extended to the retroperitoneum, thereby inducing right ureteral stenosis. The postoperative course was uneventful. The pathological diagnosis was endometriosis of the residual appendix. 相似文献

We report an unusual case of a ureteroiliac fistula due to prolonged ureteral stenting for hydronephrosis combined with an aortic-bifemoral stent graft in an inflammatory abdominal aortic aneurysm (AAA), treated with an endovascular stent graft. In a 77-year-old man ureteral J-stents were placed for bilateral hydronephrosis due to retroperitoneal fibrosis caused by an inflammatory AAA. The aneurysm was treated with an endovascular aortic-bifemoral stent graft. Three months later, the patient suffered from severe hypovolemic shock. Emergency angiography showed a fistula between the right ureter and the right common iliac artery just distal to the right leg of the stent graft. The ureteroiliac fistula was treated with a wall graft (10F). The patient recovered well and remained asymptomatic. Ureteroiliac fistula remains a rare complication of ureteral stenting. Several risk factors have been described before. This case emphazes the increased risk of an arterial-ureteral fistula due to an indwelling ureteral stent and an inflammatory AAA, especially in combination with an additional stent graft for this inflammatory AAA. 相似文献

A 32-year-old female visited our clinic with the chief complaints of macroscopic hematuria and pollakisuria in February 18, 1987. Cystoscopic examination revealed findings of cystitis but bleeding from the ureteral orifice was not observed. IVP showed right non visualized kidney and retrograde pyelography demonstrated right ureteral stenosis on the lower ureter and right hydronephrosis. Total hysterectomy, right oophorectomy and right ureterolysis were carried out in March 5. Right lower ureter was buried in the fibrous tissue approximately over 2 cm above the crossing with iliac vessels. Dark reddish colored small tumor was noticed in the stenosed ureter and resected. The histological diagnosis confirmed endometriosis. A total of 37 cases of ureteral endometriosis in the Japanese literature was reviewed. 相似文献

A case of primary carcinoma in situ of the ureter in a 77-year-old man is reported. The patient had been to another hospital with right flank pain and macroscopic hematuria. Ultrasound sonogram showed right hydronephrosis. An excretory urogram showed right hydronephrosis and stenosis of right ureter. He was referred to our hospital for further evaluation and treatment. Retrograde pyelogram demonstrated a right ureteral stricture at the level of S1-2, but no space occupying lesion was detected in the ureter. Cytology of voided urine was negative for malignant cells and no other abnormal findings were present. Probe laparotomy was performed under the preoperative diagnosis of ureteral stricture. During the operation, frozen section examination of the stenotic ureter showed carcinoma in situ and so we performed right total nephroureterectomy with a bladder cuff. Pathologic diagnosis was primary carcinoma in situ of the right ureter. The patient has been doing well for six months postoperatively with no evidence of recurrent or metastatic disease. 相似文献

We report on a case of an isolated common iliac artery aneurysm infected by Candida albicans. To our knowledge, only one other case of this condition has been reported. The patient, a 49-year-old man with diabetes mellitus and a history of fungal urinary tract infections, had recurrent right knee pain and swelling. The knee effusion grew C albicans. Mild right hydronephrosis and a 4.6-cm aneurysm of the right common iliac artery without involvement of the aorta or iliac bifurcation was revealed by means of a computed tomography scan. The aneurysm wall was inflammatory, and there was associated purulence at the time of operation. The right ureter was densely adherent to the anterior aspect of the aneurysm, but could be palpated and dissected free because of a ureteral stent that was placed before the surgical incision. The aneurysm was resected, and the proximal and distal margins were oversewn without graft placement. C albicans was found in the resected aneurysm. The patient recovered without limb-threatening ischemia or claudication, but the distance he could walk remained limited because of right knee symptoms. The aneurysm may have formed by direct extension of infection from the right ureter or by hematogenous or lymphatic spread. This case raises interesting issues about operative strategies and etiology. 相似文献
