[Hypothyroidism and immunotherapy using interferon or interleukin for metastatic renal adenocarcinoma].

The authors report a case of hypothyroidism occurring during cytokine treatment of metastatic renal cancer. This is a relatively rare complication of immunotherapy, whose aetiopathogenesis remains unclear. Possible hypotheses include an autoimmune process or direct toxicity.

[Laparoscopic drainage of a lymphocele after radical prostatectomy].

A laparoscopic procedure used to achieve transperitoneal drainage of a lymphocele that developed three months after radical prostatectomy for prostate cancer is described. The lymphocele wall was resected through a peritoneal opening. After drainage of the lymphocele, a corner of the omentum was inserted into the cavity.

[Drainage of a lymphocele after kidney transplantation, using laparoscopy].

The authors report a case of transperitoneal laparoscopic drainage of a recurrent, compressive lymphocele occurring 3 months after cadaver renal transplantation. The technique consists of creating a transperitoneal breach and resecting the walls of the lymphocele to ensure internal drainage followed by suture of a slip of greater omentum over the opened lymphatic cavity. Preoperative aspiration and computed tomography precisely defined the site of the lymphocele in relation to urinary and vascular structures, confirmed the lymphatic nature of the collection and excluded the presence of infection.

Continent urinary diversion using an artificial urinary sphincter.

We report a new and simplified method of continent urinary diversion employing a modified AMS 800 artificial urinary sphincter (AUS). Our aim in using this artificial valve is to make a stoma continent, while allowing intermittent catheterisation. The AMS 800 pump is replaced by a subcutaneous injection port.
