Bladder neck preservation during radical retropubic prostatectomy does not improve the long-term results of urinary continence but does contribute substantially to its earlier recovery, thus improving the quality of life. With proper patient selection the risk of positive margins at the bladder neck level only is reasonably low.

Adrenal insufficiency due to histologically proven bilateral metastatic adrenal involvement from colon cancer has been clinically reported only twice. Surgical treatment of bilateral adrenal metastases is seldom performed, since other metastatic localizations are usually concomitant. To the best of our knowledge, we report the first case of relatively long-term disease-free survival after bilateral adrenalectomy in a patient with adrenal insufficiency due to bilateral metastases from colon carcinoma.

Objective: To evaluate the effects of desmopressin on pressure values inside the pelvis and ureter of the rat following acute obstruction. Materials and Methods: By means of a microsurgical technique, 24 male Wistar rats were submitted to ureteral obstruction; pressure inside the ureter was recorded using a cannula and a micrometric glass column. In the treatment group (14 animals) 6 mg/kg of desmopressin were administered 30 min before the beginning of the experiment. Results: Rats pretreated with desmopressin showed a statistically significant reduction in mean intraureteral pressure following acute obstruction (p = 0.05). Conclusions: In Wistar rats desmopressin demonstrated a powerful antidiuretic effect, reducing the intraureteral pressure. The experimental model is useful for a better understanding of physiopathology of renal colic and acute obstruction.
