[Invasive angiomyxoma].

Invasive angiomyxoma is a rare mesenchymal tumour predominantly affecting women and essentially involving the pelvis, perineum and inguinal region. It is essentially characterized by a high local recurrence rate. Treatment of these recurrences is almost exclusively surgical and is not always easy to perform.

Hepatodiaphragmatic interposition of the colon--an unusual case of combined anterior and posterior types treated with an original operative technique: report of a case.

Hepatodiaphragmatic interposition of the colon is rare. The posterior type is rarer than the anterior type. We observed a case of combined anterior and posterior types and used an original operative technique with a Prolene mesh to exclude the dead space and prevent recurrence.

[Definitive ureteral stent. Technique of the future].

We report one of the first implantations of a definitive ureteral stent, MEMOTHERME, for cicatricial striction of the pelvic ureter in a patient who had undergone left pelvic ureterolithotomy in the 1950s and who later developed homolateral hydronephrosis. The analysis of this case showed that short-term results are excellent in terms of urine flow after exclusive endoscopic installation. The hospital stay is short.

[Compression of the pelvic ureter by a hypogastric aneurysm].

An isolated aneurysm of the right hypogastric artery provoked ureteral compression responsible for renal colic and evidence of uretero-pyelo-caliceal dilatation on I.V.U.
