Major venous anomalies complicating retroperitoneal surgery.

Transposition of the inferior vena cava, duplication of the inferior vena cava, circumaortic renal collar, and retroaortic renal vein constitute the four most common major venous anomalies occurring in the retroperitoneum. Recent clinical cases are presented to review the embryogenesis, incidence, and clinical importance of these anomalies and to alert the unfamiliar surgeon to their possible existence. A high index of suspicion on the part of the surgeon is required to prevent inadvertent injury to these anomalous veins and to avoid significant hemorrhage during retroperitoneal surgery.

Significance and evaluation of calcifications associated with renal masses.

Although there are numerous references in the medical literature suggesting that calification associated with renal masses is indicative of malignant disease, our recent experience with four cases emphasizes that it is not possible to predict the nature of these lesions. The significance and etiology of renal calcification are discussed as well as the indications for clinical evaluation.

The role of ultrasonics in the evaluation of renal masses.

Analysis of our experience with echography in the evaluation of renal masses reveals an error rate of 31 per cent. Presently, this technique may be useful in directing the evaluation of a renal mass to either arteriography, if a tumor is suspected, or needle aspiration and renal cystogram, if a cyst is suspected. However, echography should not replace more definitive studies.

Radical cystectomy for invasive bladder cancer in the octogenarian.

The incidence of bladder cancer increases with age. As the population lives longer, an increasing number of patients 80 years of age or older will develop invasive bladder cancer. In this study, we reviewed the outcome of 33 patients age 80 years or older treated with radical cystectomy and ileal conduit urinary diversion. Five patients received neoadjuvant chemotherapy, and 2 had salvage cystectomy after failure of external beam radiation therapy. The median age was 82 years, and the median hospital stay was 12 days. There were no perioperative deaths. Twenty-seven complications occurred in 20 patients (60.6%), of which 17 were minor (63%) and 10 were major (37%). There was no difference in the rate of complications in patients receiving neoadjuvant treatment compared to the group treated with cystectomy alone. The median survival was 3.5 years. Our results demonstrate that radical cystectomy and ileal conduit urinary diversion should not be withheld from patients on the basis of age.
