Treatment of impotence. 1. Nonsurgical methods.

Male sexual dysfunction is a problem that is quite prevalent in our society. Until recently, the only treatments for impotence were testosterone injection, sex therapy, and implantation of a penile prosthesis. These methods remain in use when appropriate. However, now that the pathophysiology of erection is better understood, the dopamine agonist, intracorporal injection, and the alpha 2-adrenergic receptor blocker have been added to the treatment list. Gadgets that artificially increase the blood supply to the penis are sometimes used. The withdrawal of drugs that affect sexual function may be sufficient.

Treatment of impotence. 2. Surgical methods.

Most patients with an organic or physical cause of their impotence can be helped, because noninvasive diagnostic testing to identify the disorder and specialized surgical techniques to repair it are available. Occlusion or leakage of the blood supply to the penis is treated with graft bypass, endarterectomy, transluminal balloon angioplasty, or vein ligation. Patients with persistent Peyronie's disease may require plaque excision and graft placement, and sometimes, a penile prosthesis. Different types of penile prostheses have been used successfully.

Male infertility. 1. Patient evaluation.

Although the cause of male infertility is often obscure, proper evaluation can reveal physiologic abnormalities on which a concept of management can be based. Evaluation includes history taking, physical examination, laboratory studies, semen analysis, radiographic studies, and occasionally, testicular biopsy and other studies. The history and physical examination are the foundation of evaluation and may provide clues to diagnosis. However, semen analysis is the most informative test in evaluation of male infertility. For optimum results, proper collection techniques must be followed and data must be carefully interpreted.

Ureteral replacements.

The clinical necessities of replacing all or part of the diseased or destroyed ureter have plagued surgeons for many years. In the past seventy years more than 100 surgical techniques have been described for ureteral replacement. Methods of replacement have fallen into four categories; nonbiologic substitutes, pedicle grafts, free grafts, and implantation and diversion. This review discusses the history and present status, and presents a look to the future in the surgery of ureteral replacement.

Blood urea nitrogen and serum creatinine. Physiology and interpretations.

Any elevations in levels of blood urea nitrogen and/or serum creatinine do not necessarily indicate structural renal disease. Conversely, blood urea nitrogen or serum creatinine values, which appear to be within the range of normal, do not by themselves rule out significant reduction in glomerular filtration rate. Any interpretation of the blood levels of these two substances must be done with the awareness that a variety of extrarenal factors can affect them. The blood urea nitrogen to serum creatinine ratio can be a valuable tool in the determination or renal functional and structural integrity.

Experimental evaluation of bladder closure techniques.

Two methods of bladder closure have been evaluated in dogs. A conventional two-layer closure including the mucosa and a single layer running horizontal mattress extramucosal closure have been compared. Observations including adequacy of healing, strength of scar, degree of inflammatory reaction, dna degree of bladder adhesions have been made. The extramucosal running horizontal mattress closure appears to approach the ideal bladder closure.
