[Knowledge, attitude and perception about obstetric fistula by Cameroonian women].

Introduction: This study seeks to identify what the women who live in Maroua Cameroon know and think about obstetric fistula.

Population And Method: It is a single hospital, cross-sectional, descriptive and comparative study. Ninety-nine women in the maternity service of the Maroua Provincial Hospital were interrogated on obstetric fistula between May and July 2005, by enquirers who were trained health agents using a questionnaire which required both closed and open answers.

[What may be expected from endorectal echography and magnetic resonance imaging in the evaluation of local extension of cancer of the prostate?].

Thirty patients presenting with a clinical stage A or B cancer underwent TRUS and MRI with a body coil prior to radical prostatectomy. Imaging and pathology were correlated to assess the limits of TRUS and MRI in pre-operative staging of prostatic carcinoma. Results showed that TRUS and MRI had a sensitivity of 42 and 66% and a specificity of 89 and 94% respectively, for the diagnosis of macroscopic capsular effraction.

[Color doppler echography in the exploration of vasculogenic impotence].

102 patients with suspected vasculogenic impotence were evaluated with color doppler sonography. Measurement of normal systolic and diastolic velocities were obtained from the cavernosal arteries of patients responding by a full erection after intra-cavernosal injection of 20 mg of Papaverine. A correlation with cavernosometry was obtained in 61 patients and with selective internal pudendal arteriography in 11.

[What may be expected from endorectal ultrasonography and magnetic resonance imaging in the assessment of local extension of cancer of the prostate?].

30 patients presenting with a clinical stage A or B cancer underwent TRUS and MRI with a body coil prior to radical prostatectomy. Imaging and pathology were correlated to assess the limits of TRUS and MRI in pre-operative staging of prostatic carcinoma. Results showed that TRUS and MRI had a sensitivity of 42 and 66% and a specificity of 89 and 94% respectively, for the diagnosis of macroscopic capsular effraction.

[Technical problems raised by renal puncture in the percutaneous extraction of coralliform calculi].

Initial puncture and dilation of nephrostomy track(s) remain difficult procedures in percutaneous extraction of staghorn calculi. Technical s adjuvants are necessary and are exposed in detail. The choice of the needle, of the wires and of the catheters for initial puncture and ureteral catheterization is explained.
