The effect of the modified Z trendelenburg position on intraocular pressure during robotic assisted laparoscopic radical prostatectomy: a randomized, controlled study.

Purpose: The Trendelenburg position has a dramatic effect on circulation, consequently increasing cerebral and intraocular pressure. We evaluated whether modifying the Trendelenburg position would minimize the increase in intraocular pressure.

Materials And Methods: In this prospective, randomized, controlled study we compared intraocular pressure in patients undergoing robot-assisted laparoscopic radical prostatectomy while in the Trendelenburg position or the modified Z Trendelenburg position.

Penile veins are the principal component in erectile rigidity: a study of penile venous stripping on defrosted human cadavers.

The human erectile mechanism is an intricate interplay of hormonal, vascular, neurological, sinusoidal, pharmacological, and psychological factors. However, the relative influence of each respective component remains somewhat unclear, and merits further study. We investigated the role of venous outflow in an attempt to isolate the key determinant of erectile function.

Retrieval of a detached resectoscope sheath beak during a TURP.

The detachment of a resectoscope beak during transurethral resection is a rare and unpleasant event. Published techniques for its retrieval are not practical to the majority of urologists. The authors outline a novel approach for the retrieval of a detached continuous-flow resectoscope plastic beak that is quick, safe, and effective.

Osteoporosis from androgen deprivation therapy in prostate cancer treatment.

Background: Bone complications from metastatic disease in prostate cancer have been well documented. Osteoporosis from androgen deprivation therapy (ADT) can further impair quality of life in this already susceptible age group.

Objective: We aimed to assess the intermediate and long term effects of ADT on bone density and the development of osteoporosis in men with prostatic cancer, and outline some practical assessment, management and treatment options.
