RESUMO
Pheochromocytoma of the urinary bladder is a rare neoplasm that often occurs with the unique symptom complex of micturitional attacks due to increased catecholamine secretion during detrusor activity. Analysis of 3 of our patients is added to a discussion of 97 cases reported in the world literature. Therapeutic decision is complicated by the absence of unequivocal histologic criteria of malignancy for these tumors. Future perspectives in determining the malignant potential of pheochromocytoma are presented and our treatment plan elaborated.

A study of serum lipid fraction changes in 15 estrogen-treated patients with carcinoma of the prostate is conducted. Estrogen therapy is known to be associated with cardiovascular complications. certain serum lipid fraction changes, particularly elevated low-density lipoprotein (LDL) and decreased high-density lipoprotein (HDL), are known to increase the risk of cardiovascular diseases. In our study, decrease in total cholesterol, increase in triglycerides, decreased LDL, and LDL/HDL ratio in combination with elevated HDL fraction suggest that the lipid changes are not the mediators of above complications.

In persons with azoospermia due to obstructive or anejaculatory causes, implantation of alloplastic silicone reservoirs onto the epididymis for collection of spermatozoa for artificial insemination, with eventual pregnancy, has become technically feasible, although there have been poor results from the procedure. Our experimental study on dogs indicates that such an epididymal reservoir can easily be constructed from a pedicled tunica vaginalis flap. Observations on the qualitative and quantitative changes in the spermatozoa of these reservoirs and conjecture about possible means of improvement of these parameters are discussed.

Spinal cord tumors commonly present with back pain, sciatica, weakness in the legs and bladder symptoms. A case is reported in which an isolated flaccid neurogenic bladder was the only presenting symptom of a spinal cord ependymoma.

Ureteral strictures occurring after ureterolithotomy may not be recognized until obstruction or recurrent stone impaction occurs in the area. We describe our treatment of this problem in 9 patients. Management varied from conservative treatment in patients having no discernible renal function on the affected side to various forms of reconstruction or reimplantation, depending upon the situation and site of the stricture. All patients were followed for a minimum of 2 years without complications. The etiopathogenesis and other methods of treatment available for this problem are discussed.
