Bladder cancer, a significant cause of morbidity and mortality worldwide, presents a unique opportunity for aggressive treatment due to the ease of transurethral accessibility. While the location affords advantages, transurethral resection of bladder tumors can pose a difficult challenge for surgeons encumbered by current instrumentation or difficult(More)
Constrained motion control of robotic end-effectors is essential for safe operation in confined spaces such as the urinary bladder. This paper presents the clinical motivation for the development of new control algorithms for robotic-assisted transurethral bladder resection and surveillance using multisegment continuum robots. The anatomy, workspace, and(More)
OBJECTIVES To present the longitudinal outcomes in an observational cohort of patients who had undergone treatment of stress urinary incontinence with a single incision mid-urethral sling (MUS). METHODS A prospective, observational study of all female patients who had undergone surgical intervention with the MiniArc MUS was performed. The surgical(More)
BACKGROUND The magnetic surgical camera is an emerging technology having the potential to improve visualization without taking up port site space. However, tilting the point of view downward/upward can be done only by constantly applying a pressure on the abdomen. This study aims to test the hypothesis that the novel concept of local magnetic actuation(More)
PURPOSE We determine whether outcomes of holmium laser enucleation of the prostate are similar in patients with and those without preoperative urinary retention. MATERIALS AND METHODS From May 2008 to July 2014, 231 patients underwent holmium laser prostate enucleation for symptomatic benign prostatic hyperplasia. Retrospective analysis was performed to(More)
INTRODUCTION Transurethral resection of bladder tumor (TURBT) and pathological staging are both standard surgical therapies for nonmuscle-invasive bladder cancer and integral parts of the diagnostic evaluation and progression monitoring of all bladder tumors. We developed and tested a dexterous robot that can fit through a standard resectoscope for(More)
PURPOSE We determined the efficacy of intravesical botulinum toxin A injection for refractory overactive bladder in elderly patients. MATERIALS AND METHODS Patients 75 years or older with refractory urinary urgency were prospectively evaluated and offered treatment of symptoms with botulinum toxin A. A voiding log was obtained and urodynamics were(More)
The demand for surgical correction of pelvic organ prolapse is expected to grow as the aging population remains active and focused on quality of life. Definitive correction of pelvic organ prolapse can be accomplished through both vaginal and abdominal approaches. This article provides a contemporary reference source that specifically addresses the(More)
Laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) are emerging platforms to further reduce the invasive profile of surgery. As feasibility of an increasing array of procedures in both platforms is being demonstrated, with out comes comparable to multiport laparoscopy, there has been a parallel(More)
PURPOSE The intent of this study was to compare urine parameters between kidney stone formers with low, expected, and high creatinine to weight ratio (Cr/kg) and to discuss implications for treatment. PATIENTS AND METHODS In this retrospective study, 381 stone formers (205 females and 176 males) with urine collections for nephrolithiasis evaluation were(More)
