Pubovaginal sling in the treatment of stress urinary incontinence for urethral hypermobility and intrinsic sphincteric deficiency

PURPOSE: This study was undertaken to evaluate the use of pubovaginal sling for the treatment of female stress urinary incontinence in patients with intrinsic sphincteric deficiency and patients with urethral hypermobility. MATERIALS AND METHODS: Sixty-two patients aging 22 to 73 years-old (mean = 49.6) with a median parity of 4.1 (range 0 - 14) who underwent pubovaginal autologous fascial sling procedures for stress urinary incontinence from August/1999 to August/2002 were prospectively analyzed. Objective pre and postoperative urodynamic evaluation was performed in all cases. The patients were divided into 2 groups: thirty-nine patients (62.9 percent) with urethral hypermobility (Valsalva leak point pressure equal or superior to 60 cm of H2O) and twenty-three patients (37.1 percent) with intrinsic sphincteric insufficiency (Valsalva leak point pressure below 60 cm of H2O). RESULTS: The average follow-up period was 24.8 months, ranging from 3 to 38 months. Three patients (4.8 percent) had detrusor overactivity before the operation, and 36 patients (58.1 percent) had voiding dysfunction before surgery. The postoperative objective cure rate was 88.7 percent for stress urinary incontinence. The study also showed that 32.2 percent of the patients had voiding dysfunction and 11.3 percent had detrusor overactivity. The mean hospital stay was 3.1 days (range 2 - 4). No difference in the above parameters was noticed between patients with intrinsic sphincteric deficiency and those with urethral hypermobility. CONCLUSION: Construction of a pubovaginal sling is an effective technique for the relief of severe stress urinary incontinence, for both patients with urethral hipermobility and with intrinsic sphincteric deficiency, having a cure rate of 88.7 percent. The high frequency of postoperative voiding urgency was not related to the detrusor overactivity as evaluated by urodynamic studies.

Prolapso de tuba uterina após histerectomia vaginal: relato de caso / Fallopian tube prolapse after vaginal hysterectomy: a case report

O prolapso de tuba uterina é complicação rara após histerectomia, com aproximadamente 80 casos descritos na literatura. A sintomatologia é inespecífica, podendo incluir sangramento genital, dispareunia e dor pélvica crônica. O diagnóstico diferencial deve ser feito com granuloma de cúpula vaginal e carcinoma de vagina. O tratamento deve ser individualizado, podendo ser realizado por via vaginal, abdominal ou laparoscópica. Relatamos o caso de uma paciente, 47 anos, com miomatose uterina, submetida a histerectomia vaginal, evoluindo com prolapso de tuba uterina após 11 meses de pós-operatório. O exame especular evidenciava lesão vegetante, friável e sangrante localizada na cúpula vaginal. Esses achados clínicos sugeriam o diagnóstico de prolapso de tuba uterina. A paciente foi submetida a nova intervenção cirúrgica, com ressecção da tuba uterina por via vaginal. O exame natomopatológico confirmou o diagnóstico e a paciente evoluiu com remissão completa da sintomatologia.
