Validation of Portuguese version of Quality of Erection Questionnaire (QEQ) and comparison to International Index of Erectile Function (IIEF) and RAND 36-Item Health Survey.

PURPOSE: To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. MATERIALS AND METHODS: To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach's α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. RESULTS: We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, p<0.001) and Spearman correlation coefficient r=0.82 (p<0.001), which demonstrated the high correlation between the QEQ and IIEF results. The correlations between the QEQ and RAND-36 were significantly low in ED (r=0.20, p=0.01) and non-ED patients (r=0.37, p=0.04). CONCLUSION: The QEQ Portuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients' psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well-being feeling.

Mechanisms predisposing penile fracture and long-term outcomes on erectile and voiding functions.

Purpose. To determine the mechanisms predisposing penile fracture as well as the rate of long-term penile deformity and erectile and voiding functions. Methods. All fractures were repaired on an emergency basis via subcoronal incision and absorbable suture with simultaneous repair of eventual urethral lesion. Patients' status before fracture and voiding and erectile functions at long term were assessed by periodic follow-up and phone call. Detailed history included cause, symptoms, and single-question self-report of erectile and voiding functions. Results. Among the 44 suspicious cases, 42 (95.4%) were confirmed, mean age was 34.5 years (range: 18-60), mean follow-up 59.3 months (range 9-155). Half presented the classical triad of audible crack, detumescence, and pain. Heterosexual intercourse was the most common cause (28 patients, 66.7%), followed by penile manipulation (6 patients, 14.3%), and homosexual intercourse (4 patients, 9.5%). "Woman on top" was the most common heterosexual position (n = 14, 50%), followed by "doggy style" (n = 8, 28.6%). Four patients (9.5%) maintained the cause unclear. Six (14.3%) patients had urethral injury and two (4.8%) had erectile dysfunction, treated by penile prosthesis and PDE-5i. No patient showed urethral fistula, voiding deterioration, penile nodule/curve or pain. Conclusions. "Woman on top" was the potentially riskiest sexual position (50%). Immediate surgical treatment warrants long-term very low morbidity.

Pieloplastia desmembrada pela tecnica de Anderson-Hynes versus endopielotomia percutanea no tratamento da estenose da junçao uretero-pielica na infancia / Open pyeloplasty (Anderson-Hynes Technique) versus endopyelotomy in the management of ureteropelvic obstruction in children

A estenose da junçao uretero-pielica (JUP) e uma das causas mais frequentes de hidronefrose em crianças, sendo responsavel por 25 por cento dos tumores abdominais nos recem-nascidos. O presente estudo compara o tratamento da estenose de JUP pela pieloplastia aberta, tecnica de Anderson-Hynes, e a endopielotomia percutanea. Treze pacientes foram submetidos a pieloplastia aberta, com idade variando de 5 meses a 5 anos, com media de 2 anos e 6 meses. Nove pacientes foram submetidos a endopielotomia percutanea, totalizando dez procedimentos. A idade destes pacientes variou de 2 meses a 16 anos, com media de 6 anos. No grupo de pacientes submetidos a pieloplastia houve melhora clinica em 10 pacientes (76,5 por cento), verificada por ausencia de dor, ganho de peso, normalizaçao do crescimento e ausencia de infecçao urinaria ou febre. A melhora radiologica foi observada em 8 pacientes (61,5 por cento). No grupo submetido a endopielotomia percutanea observou-se melhora clinica e radiologica em 83,4 por cento dos pacientes com estenose da junçao uretero-pielica de causa primaria e melhora clinica e radiologica de 100 por cento e 50 por cento, respectivamente, nos pacientes com estenose de causa secundaria. Houve um caso de recidiva da estenose em cada grupo. Com base nos resultados obtidos, conclui-se que ambos os metodos apresentam eficacia no tratamento da estenose de JUP e acompanham-se de baixa morbidade
