Assessment of sexual function in patients undergoing vasectomy using the international index of erectile function

INTRODUCTION: The present study aims to prospectively compare the sexual function in males before and after vasectomy surgery using the international index of erectile function (IIEF). MATERIALS AND METHODS: From October to December 2002, sixty-four patients who were candidates for male sterilization in the vasectomy program of the Urology Section at the General Hospital of the University of São Paulo were included. The same investigator applied the IIEF before and 90 days after the surgery. The mean scores obtained on pre and postoperative visits for all domains of sexual function were analyzed and compared with the Wilcoxon test. RESULTS: The mean patient age was 35 years (range from 25 to 48 years) and the mean number of children per man was 3. The total mean score of the IIEF was 64.06 before surgery and 65.64 after the procedure, with this difference considered statistically significant (p < 0.001). Sixty-seven per cent of the patients improved their scores, versus 17 percent and 16 percent who showed worsening or no change at all in IIEF scores following surgery, respectively. Of the 5 sexual function domains, desire and sexual satisfaction presented statistically significant improvement. CONCLUSION: This study showed that vasectomy caused a positive impact on sexual function, especially on desire and sexual satisfaction, in the majority of men undergoing surgery. There was no case of surgery-related erectile dysfunction.

Triplicaçäo ureteral / Ureteral triplication

Triplication of the ureter is rare, with less than 100 cases reported. A case of isolated of ureteral triplication is documented in a 19-year-old white man with a history of multiple episodes of upper urinary tract infection. After through physical examination and imaging studies, including ultrasonography, voiding cystography and intravenous urogram, a triple ureter was identified in the left side. The left kidney was atrophic and considered non-functional. The patient did not have any other urogenital anomaly. A nephroureterectomy was successfully performed and at 4 month follow-up the patient is asymptomatic. Ureteric duplication and triplication have been explained by multiple ureteric buds arising idependently from the Wolffian duct, and/or early fusion of one or more ureteral buds. The case herein reported, probably represents Smith's type III triplication

Tratamento contemporâneo de disfunçäo erétil através de injeçäo intracavernosa / Contemporary treatment of erectile dysfunction through intracavernous injection

Desde 1970 o tratamento da impotência sexual tem sofrido inúmeras modificaçoes. Isto se deu graças ao profundo conhecimento adquirido, através de inúmeras pesquisas, da fisiofarmacologia envolvida na ereçao. A descoberta de que substâncias vasoativas injetadas dentro dos corpos cavernosos poderiam produzir uma ereçao fisiológica trouxe nova luz ao tratamento de tal moléstia. Esta nova modalidade terapêutica, doravante denominada auto-injeçao intracavernosa, é sem dúvida o tratamento de primeira escolha para o paciente com disfunçao erétil de qualquer etiologia em 1994. Neste artigo os autores descrevem as principais drogas utilizadas nesta modalidade terapêutica, assim como o seu mecanismo de açao e complicaçoes.
