Intraureteral Metastasis From Colon Cancer Mimicking Primary Ureteral Carcinoma on FDG PET/CT.

Hematogenous or lymphatic intraureteral metastasis from distant primary cancer is very rare. We present contrast-enhanced CT and FDG PET/CT findings in a case of intraureteral metastasis from colonic adenocarcinoma 3 years after colectomy. The intraureteral showed moderate enhancement on contrast-enhanced CT and increased FDG uptake on PET/CT mimicking a primary ureteral carcinoma. This case suggests that metastatic tumor of the ureter should be considered in the differential diagnosis in patients with hypermetabolic ureteral lesion and known malignancy.

Evaluation of spiral CT imaging in the diagnosis of the primary ureteral carcinoma

Objective To explore the characteristics of the primary ureteral carcinoma (PUC) and discuss the value of spiral CT (SCT) in the diagnosis of PUC.

Multiple metachronous brain metastases from primary ureteral carcinoma

Transitional cell carcinoma (TCC) of the ureter is an uncommon urologic malignancy, with approximately 150 cases diagnosed annually. Metastatic brain disease from ureteral TCC is exceedingly rare. To our knowledge, our case report represents only the second report of brain metastasis from ureteral TCC and the only reported patient to undergo resection of their TCC brain metastasis.

Clinical analysis of 174 cases of primary ureteral carcinoma

To analyse the clinicopathological features and discuss the diagnosis, therapy and prognosis of primary ureteral carcinoma. One hundred and seventy four cases of primary ureteral carcinoma diagnosed pathologically between January 1971 and July 2002 in our institution were followed up and retrospectively studied. The incidence of primary ureteral carcinoma was increasing during the last 30 years. The mean age of occurrence was 63.7 years. The most useful methods of detecting tumors preoperatively were retrograde urogram, CT, magnetic resonance urography and ureteroscopy, with positive percentage of 87.8% (86/98), 96.0% (48/50), 95.8% (23/24), 87.0% (20/23) respectively. 131 (75.3%) cases underwent nephroureterectomy with a cuff of bladder. 171 (98.3%) cases were transitional cell carcinoma. T(a-2) and G(1, 2) tumors account for 70% of all respectively. The 5 year and 10 year survival rates were 53.1% (52/98) and 30.5% (18/59) respectively. The subsequent bladder cancer occurred in 38 cases (23.8%), and the subsequent contralateral ureteral carcinoma occurred in 6 cases (3.8%). The prognosis of primary ureteral carcinoma is poor. Tumor stage and grade are both the prognostic factors. Precise preoperative diagnosis and more effective adjuvant therapy may improve the prognosis.

Primary ureteral carcinoma: MRI diagnosis and comparison with other diagnostic imaging facilities

目的 探讨原发输尿管癌的MR检查方法、影像表现并与其他影像方法比较,评价其临床价值.方法搜集近8年来手术治疗的原发输尿管癌87例,其中35例行MR检查.使用GE1.5 T MR机,所有病例先行冠状面重T2WI水成像以显示输尿管积水,如有梗阻则在梗阻水平行T2WI和T1WI扫描,其中11例进一步做了动态增强扫描.以手术所见和病理诊断为参照,对术前各种影像诊断的原始报告进行比较分析.结果35例中MRI显示33例患侧输尿管有不同程度积水,1例无异常发现,1例仅显示肾移植术后原肾萎缩改变.横轴面扫描33例有输尿管积水者中的32例在梗阻水平显示有异常软组织占位信号.增强扫描病灶呈逐渐、均匀的轻度或中等异常对比强化.同时期输尿管癌患者术前影像检查使用率依次为:B超(94.3%)、静脉肾盂造影(IVU,59.8%),CT(52.9%),MRI(40.2%)和逆行输尿管造影(RUP,35.6%).诊断准确率依次为:MRI(91.4%),RUP(80.6%),CT(63.0%),B超(47.6%)和IVU(11.5%).结论MR水成像与传统序列结合使用能清晰显示绝大多数有输尿管梗阻的原发输尿管癌病变,在常用的影像检查手段中诊断准确率最高,在B超筛查的基础上应作为首选。

EXAMINING THE OBSTRUCTED URETER WITH INTRALUMINAL SONOGRAPHY

Intraluminal sonography was used to define, differentiate and direct better treatment of obstructing ureteral lesions. A total of 63 patients with a history of ureteral obstruction and suspected stricture were accrued for evaluation. All patients underwent retrograde contrast imaging, ureteroscopy and intraluminal sonography as part of a diagnostic algorithm. Specific sonographic criteria to differentiate lesions and stricture types were developed. Associated complicating variables defined on sonography included foreign bodies, submucosal stone fragments, ureteral wall fibrosis, mass lesions and adjacent vasculature. Endoscopic treatment was then performed with ultrasound guidance if technically feasible. A total of 63 ureters were evaluated with the preoperative diagnosis of ureteral stricture disease. All ureters were narrowed on contrast imaging in the segment where a stricture was suspected. On sonography 24 ureters (36%) had wall fibrosis with normal periureteral tissues. In general these strictures did well with endoscopic incision. Of the 67 ureters 13 (19%) were thickened or had edematous walls with normal architecture and without fibrosis. These patients all did well with expectant therapy. In contrast, 7 ureters (10%) were obstructed by segmental retroperitoneal fibrosis which did not respond to minimally invasive therapies. In addition, 8 ureters (12%) were obstructed by ureteral wall scarring and periureteral fibrosis, and required open surgical intervention. Ten ureteral strictures had adjacent vasculature, and endoscopic incisions under ultrasound guidance were directed safely away from these structures without associated morbidity. Calculi, stone fragments and foreign bodies embedded in the ureteral wall with associated inflammation were defined with sonography and responded to endoscopic therapies. The intraluminal sonographic diagnosis of ureteral endometriosis was made in 6 patients with a range of lesions from bright, hyperechoic blood filled cysts to an inhomogeneous fluid filled scar involving the wall and periureteral tissues. Primary ureteral carcinoma was also demonstrated in 2 patients after other diagnostic techniques failed. In 1 of these patients intraluminal sonography directed biopsies diagnosed submucosal tumor. Finally, 1 patient had a small periureteral urinoma on intraluminal sonography which was missed on other imaging studies. Intraluminal sonography is useful in patients with ureteral obstruction of unclear etiology as well as for selecting patients who may benefit from minimally invasive therapies and safely directing these treatments.

Diagnosis and treatment of primary ureteral carcinoma—A report of 15 cases

Fifteen cases with primary ureteral carcinomas are reported with a review of the literature. We concludeL Excretory urography is the main method of diagnosis; retrograde uretero-pyelography is more helpful in diagnosis; cystoscopy is also necessary before operation; CT is useful in diagnosing and staging; ureteroscopy could be performed if necessary; the traditional total nephroureterectomy with a cuff excision of the urinary bladder remains the basic treatment of choice; cystoscopy, excretory urography and adjuvant intravesical therapy should be carried out regularly after operation.

Carcinoma of the Ureter: Natural History, Management and 5-Year Survival

We reviewed retrospectively 53 new cases of primary ureteral carcinoma. Each patient was staged pathologically and survival by operative procedure was compared. Depth of tumor invasion is the most accurate indicator of over-all outcome. Patients with stage A tumors had an 80 per cent 5-year survival rate, compared to only 33.3 per cent of the patients with stage C lesions. Patients also were divided into 2 groups: group 1 patients had a ureteral lesion only, and group 2 patients had a ureteral tumor and a second primary urothelial lesion. No difference was found in 5-year survival rates for patients in groups 1 (48.3 per cent) and 2 (47.7 per cent). Since prognosis for patients with low stage tumors was not enhanced by an aggressive operation a more conservative approach is indicated.

Conservative surgical management for noninvasive distal ureteral carcinoma

Distal ureterectomy with direct ureteroneocystostomy facilitated by the psoas bladder hitch procedure has been used in 6 patients for management of low-grade, noninvasive primary ureteral carcinoma. All patients are alive, two to ninety-six months postoperatively. Recurrent ipsilateral urothelial malignant disease has occurred in only 1 patient, twenty-six months postoperatively, necessitating a secondary nephroureterectomy. Renal function has been preserved in the remaining 5 patients. The continued practice of conservative surgery in these cases appears warranted.

Primary ureteral carcinoma

A report of 22 cases of true primary transitional carcinoma of the ureter is presented. Evaluation of these cases shows that grades III and IV lesions have a poorer prognosis than grades I and II and that staging in ureteral tumors is a difficult task and unreliable for predicting survival. A conservative approach at management of low-grade lesions is suggested.
