[Echographic features of testicular neoplasms. Our experience].

14 patients with primitive testicular cancer underwent US and afterwards surgery. A comparison between echo-pattern and hysto-pathology was done with the following results: sharp limits and ipoechoic homogeneous pattern in leydigioma and low-staging seminoma. Presence of anechoic areas and irregular limits: teratoma and embrionary carcinoma with no correlation with the staging. Inclusively no correlation between echo-pattern and staging of neoplasm or presence of neoplastic lymphnodes was observed.

[Vesico-cutaneous fistula of the thigh as a late manifestation].

Vesico-cutaneous fistulas rarely occur in the urinary tract (1.7% of all urinary fistulas). Trauma, neoplasias, inflammation and iatrogenic pathologies are among the principal causes. The external mouth of the fistula is usually found in the hypogastric area, scrotum, perineum and rarely elsewhere. This report describes the case of a 48 year old woman who, after severe trauma suffered bladder laceration, treated only with cystorraphy. Sepsis and gangrene followed involving the pubic area and the right thigh, associated with acute renal and adrenal gland cortex failure. After emergency treatment, the patient was discharged with an indwelling catheter. Ten months later she was referred to our urology clinic because of a suspected bladder-vaginal fistula. The indwelling catheter was removed and the bladder resumed functioning well. Six months later the external mouth of the fistula appeared on the right inner thigh. NMR confirmed the diagnosis of a vesico-cutaneous fistula. Surgery resolved the abnormality.

[Vesico-intestinal fistula in Crohn disease: the role of echography in its diagnosis].

Ultrasound is in widespread use in the study of gastrointestinal pathologies. In Crohn disease it is helpful in diagnosing complications such as thickening of the bowel loop walls, abscesses, lymph node enlargement and vesical-enteric fistulas. This report presents two cases in which vesical-enteric fistulas were visualized by US; confirming a diagnosis of Crohn's disease in one case, and diagnosing the fistula during the follow-up in the second patient in whom Crohn's disease had previously been diagnosed.

[Traumatic injuries of the urethra: an echographic study].

US in the lower urinary tract usually explores the bladder and the prostatic urethra. In this study we used US instead of x-rays to visualize the remaining urethra in 42 patients. US was useful in the presence of urethral trauma. The site and extent of injury, particularly peri-urethral lesions (hematomas, urinary collection and abscesses in relation to the urethra) were observed. Ultrasound's efficacy and reproducibility were also useful in post-operative follow-ups.

[Role of ultrasonography in the follow-up of surgically treated patients. Upper urinary tract. Complications after conservative surgery].

The Authors describe the purposes of ultrasonographic follow-up after both conservative surgery and endoscopic or endourological operations of the upper urinary tract. In these cases ultrasonography evaluates the results of normal surgery, the presence of early or late complications, and of iatrogenic lesions. The echo-patterns of deformations in the outline of the kidneys, of hematic, urinary or lymphatic collections (both retroperitoneal and intraperitoneal), of fistulas, of sclero-lipomatosis and of post-cicatrization hydronephrosis are described. The importance of evaluating the degree of obstruction by a dynamic ultrasonographic study with furosemide-test is emphasized. The ultrasonographic monitoring of urethral and pyelostomy setting of catheters is also described. The echo-patterns of retroperitoneal and intraperitoneal fluid collections and renal hematomas, in relation also the kind of fluid contained are widely discussed.

Are retroperitoneal lymph node metastases a major problem in endometrial adenocarcinoma? Diagnostic and prognostic assessment with lymphography.

The results of foot lymphography in 295 patients with endometrial carcinoma observed from 1968 to 1978 at two institutions are reported. One hundred and eighty-two were new cases, 61 were recurrences, and 52 were patients who underwent restaging diagnostic procedures without clinical evidence of disease. The incidence of lymphatic spread was correlated with the clinical stage, the pathologic stage, and the extent of recurrent disease. In fact, in the 182 new cases, at clinical stage, the pathologic stage, lymphography was positive in 8.9% of patients at Stage I, 28.6% at Stage II, 57.1% at Stage III, and 66.6% at Stage IV disease; at pathological stage, lymphography was positive in 8% of patients at Stage I, 14.8% at Stage II, 39.3% at Stage II, and 53.3% at Stage IV disease. There was lymph node involvement in 47.5% of the 61 pretreated patients. Finally, in 52 pretreated patients with no evidence of disease, the incidence of lymph node involvement was 7.7%. In new cases, metastases were found only in the pelvic nodes in 56.2% of the patients and only in the para-aortic nodes in 9.5%; in 34.3%, both chains were simultaneously involved. The five-year survival rate for patients at Stage I, II, and III disease with positive lymphography was 35% as compared with 73% for negative cases. In patients at Stage I and II, the difference of survival was equal to 24%. The reliability of the results is confirmed by the concordance with the data of the literature on histologic involvement, by the first radiologic-pathologic comparison, and by the clinical course of the positive cases. Lymphography is of unquestionable value for an appropriate staging and for a correct plan of treatment.
