[Vasectomy and arteriosclerosis: are they related?].

There has been a remarkable increase in recent years in the demand by the male population of vasectomy procedures as a sterilization technique. Several recent studies have questioned its safety. We have evaluated in 103 healthy males the effect of vasectomy on plasma lipoprotein concentration, blood pressure and body mass index, all acknowledged risk factors for arteriosclerosis. No statistically significant change was found either in plasma lipoprotein concentration or blood pressure. The only statistically significant (p < 0.05) change was in terms of body mass index, which experiences a mean increase of 1.22%. Our results cannot confirm that vasectomy plays a role as risk factor for arteriosclerosis.

[Congenital urethral diverticulum].

Presentation of two cases of congenital diverticula of the bulbar urethra. The objective of this paper is to discuss the etiopathogenic theories, sings and symptoms, current diagnostic methods and therapeutic indications, and to conclude that this type of diverticula do not present a florid symptomatology, endoscopy being the best diagnostic and therapeutic method. Finally, a review of the literature is made based on two clinical cases.

Vesical tumors in patients under 25 years of age.

Behavior of transitional cell carcinoma of the bladder during the third decade of life remains a controversial subject. During the period 1980-1988, we treated 7 patients (4 male and 3 female), 25 years of age or less (mean age 19.3, range 14-25), with transitional cell carcinoma of the bladder. Until now, all patients are alive and without disease during 12-50 months after surgery. In 6 of the 7 patients, endoscopic resection was the choice treatment for superficial stage A/O. The seventh patient underwent a partial cystectomy for a B1 Jewet stage cell carcinoma. We conclude that transitional cell carcinoma of the bladder in patients under 25 years of age has a less aggressive biological behavior. Therefore, ultrasonographic examinations and serial urine cytology represent the elective test for follow-up. Cystoscopy would only be performed in doubtful cases.

[Entero-urinary fistula. A study of 22 cases].

We performed a retrospective study on 22 patients with entero-urinary fistulas that had been diagnosed and treated at the Hospital Clinico i Provincial in Barcelona during the period spanning 1981-1988. Fistulas were classified according to the organs or parts with which they communicated. Among the important etiogenic conditions were diverticular disease of colon. Crohn's disease, actinic lesions, trauma and xanthogranulomatous pyelonephritis. The clinical manifestations were principally urological in the form of recurrent urinary infection and terminal pneumaturia. The most useful diagnostic techniques were cystoscopy; serial voiding cystourethrography (SVCU), retrograde urethrography and pyelography. Treatment was by surgery in all cases. Diversion procedures or surgical excision of the fistulous tract were performed as warranted by each case. The etiopathogenic, morphological and therapeutical aspects of vesico-enteric fistulas are discussed.

[Enterovesical fistula caused by a prosthesis made of synthetic material].

Enterovesical fistulas affect mainly male patients, due to the interposition of the uterus in women. They can be caused by neoplastic, inflammatory or traumatic processes. A case of ilovesical fistula due to migration of a silastic plate used to repair an epigastric infissional hernia is presented. This case has two distinctive features: first, the cause is extraurological, causing a fistula between both systems due to an inflammatory process. Secondly, we report the long distance travelled by the synthetic mesh, causing a peculiar clinical picture five years after its implantation.

[Vascular complications of kidney transplant. Stenosis of the renal artery].

The present paper analyzes the incidence of vascular complications and their treatment, in a series of 500 consecutive Heterotopical Kidney Transplants (KT), performed in our Service between January 1978 and December 1988. There was a total of 14 (2.8%) complications of which 8 (1.6%) correspond to renal artery stenosis. Of the 8 cases with renal artery stenosis, in 2 of them primary surgical treatment was indicated. The first one was a transplantectomy (TRX) and the second one reconstructive direct surgery. In the 6 remaining patients a Percutaneous Transluminal Angioplasty (PTA) was indicated. In three of these patients the stenosis resolved although one of them needed a second dilatation. In the last three there was: a thrombosis requiring TRX, a post dilatation anuria added to failure in the treatment of HT and which, finally, had to undergo surgery, and a third failure that could not be resolved by surgery and had to be subjected to graft nephrectomy. One of the patients in the surgical group died.
