Varicocele: medical and surgical treatment.

Varicocele is the most frequent finding in male infertility. Thirty percent of infertile male patients requesting treatment present with varicocele. Between December 1971 and December 1984, 151 infertile patients presenting varicocele were treated in this study: 28 underwent medical treatment, 38 surgical treatment, and 23 both medical and surgical treatment. The spermograms of all the patients were studied before and after treatment. The following variables were considered: volume, sperm count, percentages of general motility and of grade III sperm, and of oval forms. There was not a significant statistical difference in the analysis of the spermogram parameters before and after treatment in the three groups. The pregnancy rate for the medical-surgical group was 60.9% and for the surgical group 47.4%--not a statistically significant difference. The purely medically treated group had a pregnancy rate of 25%, which is significantly lower than the other groups.

The importance of vaginal infection on recurrent cystitis in women.

Forty-one women with a clinical history of recurrent urinary infection were studied. The aim of this study was to correlate the importance of vaginal infection and theincreased incidence of urinary infection. By using statistical methods, we came to the conclusion that the presence of vaginal infection is not related to the recurrence of urinary infection. Vaginal contaminations certainly permit the increase of urinary infection; there must be other host-related factors, however, that are more important for the recurrence of urinary infection.

[Traumatic urethral stenosis in children].

A study is made of 20 children suffering from postraumatic, urethral stenosis and they compare the different techniques used in repairing it. Different methods have been proposed but all produce poor results and doubts always arise in a specific case. The stenoses presented in our study occurred at different levels; four in the bulbar urethra and 16 in the membranous urethra. The patients have been divided into four groups, according to the surgical technique applied. The results have been assessed according to the functioning, radiological aspect and the absence or presence of urinary infection. With reference to the functional aspect, 89.5% presented good results, which is greater than those registered in adults. The explanation may lie in the better, local conditions at the time of surgery and the fact that none of these stenoses were of inflammatory origin.
