Recurrence risk factors in patients with transitional cell carcinoma of bladder
      
Methods: An analysis on recurrence-related factors was made by Cox's proportional hazards model analysis and logistic multiple linear regression model analysis in 212 patients with transitional cell carcinoma treated surgically from 1995~2001.

In this study, we report the ultrasonic results of145 nonfunctioning kidneys out of 123 patients demonstrated by operation, discuss the ultrasonic differential method for the nonfunc-tioning kidney and analyse the causes of missing or failing to diagnose the 9 nonfunctioning kidneys out of ,8 patients.The causes of 145 nonfunctioning kidneys include hydronephrosis 43.4%(63/145), tuberculous abscess of the kidney 29% (42/145), renal carcinoma 8.3%(12/145), polycystic kidney 5.5%(8/145), carcinoma of the renal...

In this study, we report the ultrasonic results of145 nonfunctioning kidneys out of 123 patients demonstrated by operation, discuss the ultrasonic differential method for the nonfunc-tioning kidney and analyse the causes of missing or failing to diagnose the 9 nonfunctioning kidneys out of ,8 patients.The causes of 145 nonfunctioning kidneys include hydronephrosis 43.4%(63/145), tuberculous abscess of the kidney 29% (42/145), renal carcinoma 8.3%(12/145), polycystic kidney 5.5%(8/145), carcinoma of the renal pelvis 4.8%(7/145), renal hypoplasia 4.1%(6/145), unilateral agenesis of the kidney 3.5%(5/145), 1 case of renal cyst and 1 case of old clot in the renal pelvis. The rate conforming the ultra sonic diagnosis to the final diagnosis and missing or failing to diagnose are 93.8%(136/145) and 6'.2%(9/14S) respectively. The major causes of misdiagnosis include; (1) The affections are too small to be differentiated, which include 3 cases of the renal hypoplasia-and 1 case of the ureteropeivic juncton tumor. ( 2 ) Nonspecific appearances on ultrasonic tomography,, we took 2 cases of the hydronephrosis complicating nephrolithiasis for the polycystic kidney and the pyonephrosis respectively. (3) Lack of the experience using the method of combining scan in early stage, as l case of old clot in the renal pelvis for the renal carcinoma and 1 case of adenocarcino- ma of the kidney superving transitional cell carcinoma for the pyonephrosis.

本文报告经手术等方法证实的123例145个无功能肾的超声结果,讨论无功能肾的超声鉴别方法并分析8例9个肾脏漏诊、误诊原因。 145个无功能肾最后原因包括:肾积水43.4%(63/145);结核肾脓肿29%(42/145);肾癌8.3%(12/145),多囊肾5.5%(8/145);肾盂癌4.8%(7/145);肾发育不全4.1%(6/145);肾缺如3.5%(5/145);以及肾囊肿和肾盂内陈旧性血块各一例。超声诊断与最后诊断符合率为93.8%(136/145),漏诊及误诊6.2%(9/145)。误诊原因主要有以下几种情况:①病变过小不易分辨,包括3例肾脏发育不全和1例肾盂输尿管连接部肿物的漏诊;②超声不具特异性。肾积水伴肾结石2例诊为多囊肾和脓肾;③早期应用复合扫描方法及经验不足:一例肾盂内陈旧性血块诊为肾肿瘤,1例肾腺癌伴移行细胞癌诊为脓肾。

Purpose To diseuss CT findings of 6 cases of tirachal anomalies in ouler to enhance the knowledge of this diseases and choosing snitahle examination methorl. Methde All 6 cases of urachal anomalies were eded with CT seans(plain, enhanced) and proved by surgerv and pathology. Redts Among of 6 cases of urachal anomalies, urachal fistula asariated with infection 1 case, transitional cell careinoma 1 case, urahal cyst 2cases,urachal cyst associated with infection and adenocarcinoma 1 cases each. CT scans showed cystic mass of middle line in inferior abdominal wall, peripheral enhancement or nodular enhancement with intravenous injection of contrast medium.The authors comidered that irreghar cystic wall and nodular protrusion were signs of malignant chang. Conclusion CT scan can demonstrate the location, shape. extent and density of lesions as well as its relation with adjacent structures, thereby providing useful information to guide therapy. The authors were of the opinion that CT scan is a valuable methed for diagnosing this disease.

目的探讨脐尿管异常的CT表现,旨在提高对该病的认识和合理地选择检查方法。方法6例脐尿管异常患者均经CF扫描(平扫及增强)诊断和手术病理确诊。结果6例中1例脐尿管瘦伴感染,1例脐尿管移行细胞癌,2例脐尿管囊肿,1例脐尿管囊肿伴感染,1例脐尿管囊肿伴脐尿管腺癌。CF表现为下腹壁近中线的囊性占位;增强扫描,周边强化或结节状强化。囊壁不规整,结节状突起者是恶变的征象。结论CT检查能明确病变的部位、形态、范围、密度及与邻近结构的关系,对临床治疗有指导作用。CT是诊断该病有价值的检查方法。

This article concerns with the roles of renal arteriography and CT in diagnosing renal hypwascular space occupying neoplasm 8 cases we dealt with were confirmed either pathologically or by follow - up as renal transitional cell carcinoma in 4, epithelium carcinoma in 1, renal metastasis of pulmonary carcinoma in 1 and renal stroma bolld clot in 2. Renal arteriography accurately differentiated renal malignancy from other bening mass by the presence of characteristic small patchy tumor blood vessels, blood vessel displacement and tumor stain. CT with its high,- density resolution is better in dealing with small renal lesions. This scaning enhances the accuracy of differential diagnoses. For those which was uncertain by CT such as remote renal bolld clot, renal arteriography assisted to rule out the presence of neoplasm.

本组报告8例经病理及复查证实的肾少血管性占位病变的肾动脉造影与CT诊断,其中肾移行细胞癌4例、鳞癌1例、肺癌肾转移1例、肾内积血2例。肾动脉造影以其特征性的小斑点状肿瘤血管、血管移位及肿瘤染色等征象作出肾癌或其它占位病变的诊断,准确性高。CT则以高密度分辨率较肾动脉造影易于发现较细小的病灶,尤其是薄层扫描。对一些CT定性有困难的病例,如肾内巨大陈旧性血块等,结合肾动脉造影可排除肿瘤的存在。
