Ureteral obstruction can be secondary to a lot of reason. We present a uncommon case report of ureteral obstruction to Rosai-Dorfman disease. The form of clinic presentation is described, the diagnostic methods used and the therapeutic management.
We present an uncommon case of retroperitoneal malignant schwannoma diagnosed accidentally. The clinical, diagnostic and therapeutic features are discussed.
Case report of a retroperitoneal liposarcoma pleomorfico with calcification in diagnosed in our hospital. We comment on its clinical characteristics, diagnostic methods and treatment. We likewise comment the possible differential diagnoses.
A case report of kidney polycystic and horseshoe kidney coincidence in the same patient. They are two congenital associated renal diseases uncommon for urologists. The form of clinic presentation is described, the diagnostic methods used and the therapeutic management.
Presentation of 9 cases of synergistic genitalia and perineum necrosing fascitis treated in our service over the last 5 years. The contents of the disease and its terminology has been reviewed by the light of the existing literature. In our series, patients mean age was 65 years. Three of our 9 patients had diabetes mellitus, and also 3 had liver disease due to alcohol. The initial septic focus was found in 8 cases, and in 4 it was urological, basically urethra's stricture. The most frequently involved germs were aerobe-anaerobe associations. Mortality was 11%.
This article reports our case series of testicle germinal cell tumours, consisting of 14 cases, between 1974-1991. 42.85% (6 cases) were seminomas, 4 (66.6%) in Stage I. There was one case (16.6%) in Stage III and another one in Stage IV. 14.29% (2 cases) were embryonic carcinomas, one in Stage I and one in Stage II. Teratomas represented 14.29% (2 cases), in Stages I and IV respectively. There were 4 cases of mixed tumours (2 cases) in which teratomatous components (3 out of 4) were predominant. 50% were in Stage I and 50% in Stage III. Inguinal orchiectomy was performed in all cases, and three received radiotherapy (seminomas in Stages I (2 cases) and III), with survival ranging from 1 to 7 years. Two cases (seminoma and embryonic carcinoma) received chemotherapy under different regimes depending on the time of diagnosis. One patient has survived 11 years following rescue lymphadenectomy while the other one died 14 months later from pulmonary metastasis. Among the mixed tumours, 50% (2 cases in Stages II and III) died 5 and 11 months afterwards without further treatment due to overall affectation at diagnosis. An abstentionist approach in Stage I (seminomas and non-seminomas), which was "strictly" applied in 5 cases showing disease-free survival ranging from 1 to 5 years, is defended. Follow-up was not feasible in 2 cases (14.2%). Both the diagnostic means and a review of treatment by Stages, reflecting the evolution of chemotherapy and the results obtained, are analyzed. Also the most widely accepted approaches in the management of these tumours.
Two additional cases of complete testicular feminization syndrome or Morris syndrome are described. The patients had consulted for primary amenorrhea. Patient work up revealed a female phenotype, hormone profile and 46,XY karyotype. They were submitted to abdominal surgical exploration and orchidectomy of the cryptorchid male gonads. The potential etiologic factors, pathogenesis, incidence and clinical features of this syndrome are discussed. Furthermore, the surgical treatment and outcome are described, highlighting the incidence of gonadal malignancy if these are not removed early.
We report on 10 cases of bladder wall calcification after mitomycin C instillation. The cystoscopic and microscopic features of these lesions are described. In our view, these lesions can be ascribed to the use of mitomycin C instillation therapy immediately after TUR. Because they are asymptomatic and occasionally present features of tumor recurrence, biopsy is advocated to determine the true nature of these lesions.
During a period spanning 11 years, 392 patients diagnosed as having tumor of the bladder were treated at our department. Of these, 9 were patients under age 40. We compared the anatomopathological features and course of the disease. The foregoing condition was suspected on the basis of the urographic findings. We emphasize the need to perform endoscopic inspection and urinary cytology before discarding the presence of a bladder tumor. The anatomopathologic conditions of anaplasia and infiltration are frequently more favourable in this younger patient group, indicating a better prognosis. However, the natural history of tumors with histopathologically similar features is not influenced by age.
We describe the urological manifestations arising from hematoma of the left iliac psoas that developed in the course of anticoagulant therapy in a 54-year-old patient with a mitral prosthesis. The onset of the clinical picture was acute and mimicked left reno-ureteral colic. Ultrasound and CT were decisive in making the diagnosis, revealing a left retroperitoneal mass in the anterolateral aspect of the left psoas muscle. Intravenous urography evidenced the urological repercussions of the disease process consisting of medialization of the left ureter, ureterohydronephrosis, and anterior and lateral displacement of the kidney. Although this condition is considered by most to be a surgical emergency, we opted for conservative treatment because the patient had no hemodynamic instability, severe obstructive uropathy or signs or crural paralysis. The literature on the urological repercussions of psoas hematomas due to anticoagulant therapy is briefly reviewed.
