ABSTRACT
Accurate staging of prostatic carcinoma requires determination of the status of the regional draining lymph nodes. Pelvic lymphadenectomy is the definitive examination but has certain morbidity and even mortality. Lymphography is safe but may not be sufficiently accurate. A total of 41 patients with clinically localized disease and abnormal or suspicious lymphograms underwent percutaneous lymph node biopsy. Ten of 11 patients (91 per cent) with abnormal lymphograms and 14 of 30 (47 per cent) with suspicious lymphograms had positive cytology studies. Of the suspicious defects an unopacified void in a nodal chain most frequently was positive. Of 22 potentially curable patients with stages A and B1 disease 12 had metastatic disease.

The rapid increase in the number of vascular surgical procedures done has led to a new class of iatrogenic ureteral injuries. Vena caval ligation, bilateral lumbar sympathectomy, bypass procedures and abdominal aortic aneurysmectomy produce the majority of these injuries. Established principles useful in the repair of iatrogenic injuries following a gynecologic or colonic operation often are inapplicable.

Six cases of renal angiomyolipoma are reviewed. In 5 of these 6 cases a characteristics radiolucent fat sign was present overlying the renal mass. In 10 cases of hypernephroma selected only on the basis of a tissue diagnosis and the availability of a pre-injection scout film this sign was not present. The recent literature is reviewed on the radiographic diagnosis of angiomyolipoma. We conclude that angiography is not reliable in the differentiation of angiomyolipoma from hypernephroma. However, demonstration of a radiolucency on the pre-injection scout film is virtually pathognomonic of angiomyolipoma. Tomographic cuts without contrast injection may increase diagnostic accuracy.

A young man with a palpable ectopic testis underwent right testis biopsy and orchiopexy. Since histological findings of the biopsy specimen revealed an unsuspected intratubular carcinoma in situ and evidence of diminished spermatogenic potential, an inguinal orchiectomy was done. This appears to be the first reported case of a tumor of this type developing in an undescended testis.

Retroperitoneal fibrosis may occur secondary to metastatic neoplasm and may simulate the features of the idiopathic variety. A case of retroperitoneal fibrosis due to gastric carcinoma is presented and the historical, physical, cystoscopic, urographic, operative, and pathologic similarities to the idiopathic form discussed. Generous biopsy of retroperitoneal plaques and careful pathologic examination are stressed to avoid missing malignant disease.
