Malacoplakia of the ureter.

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.     

Malacoplakia of the bladder: Efficacy of enoxacine therapy

Malacoplakia of the urinary bladder was seen in a 69-year-old woman with haematuria. We firstly treated her with distigmine bromide, ascorbic acid and trimethroprim-sulfamethoxazole. Haematuria subsided but the lesion did not change after 6 weeks. Thereafter we tried enoxacine therapy. Eight weeks after the medication the tumorous leson disappeared. Bladder biopsy performed 4 months after the initiation of the treatment revealed predominantly granulation tissue. We can find no previous case treated successfully with long-term enoxacine.     

Endometriosis of the ureter and urinary bladder

Endometriosis is a benign growth of ectopic endometrial mucous membrane which has maintained the histological characteristics and biological reactions of uterine mucous membrane. In only 1-2% of cases does it occur in the urinary system, most commonly in the urinary bladder. Such an endometriosis is often diagnosed very late due both to its commonly asymptomatic course and its rarity. Individual therapy is dependent on the age of the patient, the wish for children and the extent of the growth. For endometriosis covering a large area, surgery is recommended. Methods of choice are laparoscopic bladder resection for the urinary bladder, ureterocystoneostomy using the Psoas hitch for the distal ureter, end to end anastomosis or endoscopic incision for short, proximal cases, and for extended areas, ileum cross-bridge attachment or kidney mobilization using nephropexy.     

Malacoplakia of the bladder: efficacy of bethanechol chloride therapy.

Present evidence suggests that malacoplakia is the result of a functional defect in the mononuclear cells of the lesion caused by a deficiency of cyclic 3',5' guanosine monophosphate. This defect results in the impaired ability of the macrophage to release lysosomal enzymes necessary for the digestion of phagocytized bacteria. The persistent inflammatory reaction produces the characteristic granuloma of malacoplakia. Previous laboratory studies indicate that the phagocytic defect is reversible by cholinergic agonists, which led to the use of bethanechol chloride in the treatment of patients with malacoplakia. We report on 3 patients with vesical malacoplakia who were treated successfully with bethanechol chloride.     

Malacoplakia presenting as a pseudotumor of the bladder in cadaveric renal transplantation

Genitourinary malacoplakia in renal transplant patients is rare. We report a case of malacoplakia of the bladder, which presented as a vesical tumor.     

Replacement of the ureter using the urinary bladder

Summary The combination of two well established methods — the bladder-psoas-hitch procedure and the Boari flap — succeeded in replacing 2/3 of the lower ureter. After encouraging results on dogs, we performed this method successfully in one patient.Dedicated to Professor Dr. Wilhelm Brosig, on his 60th birthday, November 27th, 1973.     

Ectopic insertion of a single ureter into the bladder adjacent to the contralateral ureter

We report a 30-year-old female with a single ectopic ureter that opens into the bladder adjacent to the right ureter.     

An intussuscepted ileal ureter bladder nipple

We report a case of an intussuscepted bladder nipple following construction of an ileal ureter. The ileal ureter has become a valuable option in reconstructing the urinary system. This complication bears consideration during construction of an ileal ureter and stresses the need for close observation of these patients.     

输尿管膀胱再植术中插入法吻合的效果观察

目的探讨输尿管膀胱再植术中插入法吻合的效果。方法对46例患者采用插入法吻合行输尿管膀胱再植术,回顾性分析患者临床资料。结果患者均顺利完成手术。输尿管膀胱吻合时间6~15 min,平均10 min。术后随访6~36个月,未发现尿漏、严重输尿管膀胱吻合口狭窄和膀胱输尿管反流等并发症。6例术前肾功能下降患者,术后明显好转。1例轻度吻合口狭窄患者,经输尿管镜扩张及延长留置双J管后,明显改善。2例膀胱造影发现有轻度反流,但均未出现肾功能损害。结论插入法吻合输尿管膀胱再植术,疗效可靠、操作简单、并发症少,是一种理想的输尿管膀胱吻合术式。
