Ureteric compression by mesenteric desmoid tumours. Report of two cases.

The authors report two cases of abdominal fibromatosis corresponding to Gar dner's syndrome, causing hydronephrosis by extrinsic ureteric compression i n young men in whom any form of surgical resection would have been in vain. These cases of ureteric compression were treated endoscopically by placeme nt of a double J ureteric stent associated with treatment by tamoxifen in o ne case and sulindac in the other with apparent stabilization of the diseas e. The two patients are regularly followed in the department with ureteric stent replacement two to three times a year.
