BACKGROUND: Robot-assisted laparoscopic prostatectomy (RALP) requires pneumoperitoneum and the Trendelenburg position to optimize surgical exposure, which can increase intracranial pressure (ICP). Anesthetic agents also influence ICP. We compared the effects of propofol and sevoflurane on sonographic optic nerve sheath diameter (ONSD) as a surrogate for ICP in prostate cancer patients who underwent RALP. METHODS: Thirty-six patients were randomly allocated to groups receiving propofol (propofol group, n = 18) or sevoflurane (sevoflurane group, n = 18) anesthesia...

With an increase in their prevalence, it has become apparent that both benign prostatic hyperplasia and radical prostatectomy for cancer can induce inguinal hernia development. An inguinal hernia is a common late complication following radical prostatectomy, with an occurrence rate of 12-25%. Following radical prostatectomy, the space of Retzius can develop adhesions to surrounding tissue, often causing difficulty during inguinal hernia repair. Conversely, inguinal hernia repair before radical prostatectomy also induces severe adhesions around the space of Retzius and causes difficulty during radical prostatectomy...

INTRODUCTION: Extended lymph node dissection (ELND) compared to limited lymph node dissection (LLND) at time of prostatectomy improves staging and lymph node (LN) yield. The effect on biochemical recurrence (BCR) and survival is less well understood. We sought to evaluate the benefit of robotic ELND and LLND with respect to BCR. MATERIALS AND METHODS: Between 2008-2012, 584 consecutive men with intermediate or high risk clinically localized adenocarcinoma of the prostate underwent robotic assisted radical prostatectomy (RARP) with concomitant LLND (n = 326) or ELND (n = 258)...

Prostate cancer is the most common solid organ malignancy in men in the USA with an annual incidence of 105 and an annual mortality rate of 19 per 100,000 people. With the advent of PSA screening, the majority of prostate cancer diagnosed is organ confined. Recent studies including the SPCG-4 and PIVOT trials have demonstrated a survival benefit for those undergoing active treatment for localized prostate cancer. The foremost surgical option has been radical prostatectomy (RP). The gold standard has been open radical retropubic prostatectomy (RRP); however, minimally invasive approaches including laparoscopic and robotic approaches are commonplace and increasing in popularity...

Prostate cancer is the most commonly diagnosed noncutaneous cancer and second leading cause of death in men. Many patients with clinically organ-confined prostate cancer undergo definitive treatment of the whole gland, including radical prostatectomy, radiation therapy, and cryosurgery. Active surveillance is a growing alternative option for patients with documented low-volume and low-grade prostate cancer. However, many patients are wanting a less morbid focal treatment alternative. With recent advances in software and hardware of magnetic resonance imaging (MRI), multiparametric MRI of the prostate has been shown to improve the accuracy in detecting and characterizing clinically significant prostate cancer...

Obesity is a known risk factor for prostate cancer progression and may contribute to poor treatment outcomes. However, little is known concerning the relationship between obesity (body mass index [BMI] ⩾ 30) and the urinary incontinence (UI) of patients after radical prostatectomy (RP). The goal of this study was to focus on the prevalence and duration of UI after RP with specific attention to the BMI. Subsequently, trials were identified in a literature search of PubMed, Embase, Cochrane Library, Web of Science, and Google Scholar using appropriate search terms...
