PURPOSE We developed a neural network to identify patients with bladder cancer more effectively than hematuria and cytology. The algorithm is based on combined urine levels of nuclear matrix protein-22, monocyte chemoattractant protein-1 and urinary intercellular adhesion molecule-1. MATERIALS AND METHODS A randomized double-blinded study of voided urine(More)
OBJECTIVE To review a multi-institutional series of robot-assisted nephroureterectomy (RANU) for management of upper urinary tract urothelial carcinoma (UUTUC) with respect to technique and perioperative outcomes. PATIENTS AND METHODS Between May 2007 and July 2011, 43 RANU were performed at three institutions for UUTUC with review of perioperative(More)
Microsurgical vasectomy reversal is a technically demanding procedure. Previous studies have shown the possible benefit of robotic assistance during such procedures. Our goal was to compare robotic assisted vasovasostomy and vasoepididymostomy to standard microsurgical vasovasostomy (MVV) and vasoepididymostomy (MVE). The use of robotic assistance for(More)
PURPOSE Microsurgical denervation of the spermatic cord has been done to treat chronic orchialgia. However, identifying the site of spermatic cord nerves is not feasible with an operating microscope or robotic stereoscope. We used multiphoton microscopy, a novel laser imaging technology, to identify and selectively ablate spermatic cord nerves in the rat.(More)
Previous studies have shown that robot-assisted microsurgical vasovasostomy (RAVV) has technical advantages over pure microscopic vasovasostomy (MVV) in animal and human models. This study presents a video technique and initial results for RAVV in 20 human cases compared with 7 MVV cases by a single fellowship-trained microsurgeon from July 2007 to June(More)
PURPOSE OF REVIEW Since its inception in early 2000, robotic assistance with urologic procedures continues to expand. The magnification, three-dimensional visualization, and surgical control offered by the latest daVinci Si-HD system has led to its integration into microsurgical procedures for male infertility. The addition of robotic assistance may allow(More)
The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy, unparalleled to any previous visual loop or magnification techniques. This technology revolutionized techniques for microsurgery in andrology. Today, we may be on the verge of a second such revolution by the incorporation of(More)
PURPOSE We devised a model to predict, preoperatively, the need for a vasoepididymostomy (VE) when performing a vasectomy reversal. Urologists could use it to identify those patients who need a referral to an experienced VE surgeon. MATERIALS AND METHODS We performed a retrospective review of 483 patients who underwent vasectomy reversal by a single(More)
OBJECTIVE To determine the adherence by laboratories across the United States to the standard semen analysis guidelines and parameter reference ranges 10 years after being set by the World Health Organization (WHO) in 1999 and to compare compliance between regional laboratories vs. specialty assisted reproductive technology (ART) laboratories. DESIGN(More)
PURPOSE Some urologists who perform vasectomy reversals are not experienced with performing VE. A model to preoperatively identify patients who may require referral to an experienced VE surgeon was created (). We tested the model at multiple institutions. MATERIALS AND METHODS The model had previously been designed in 483 patients who underwent vasectomy(More)
