Abstract Aim: To present the point of technique of robotic distal ureterectomy under cystoscopic guidance with pelvic lymphadenectomy (PLND), ureteral reconstruction with and without a psoas hitch in patients with distal ureteral urothelial cancer (DUCC) and to review the current literature.
Methods: The various steps of operative technique of robotic PLND, distal ureterectomy under cystoscopic guidance, ureteral reconstruction with and without a psoas hitch in patients of DUCC are described. Several tricks have been highlighted to undertake such procedure. The published English literature was also searched using the key words; robot, laparoscopy, ureteral reimplantation, distal ureterectomy, psoas hitch,… More >

Abstract Objective: To evaluate the safety and feasibility of robotic-assisted radical cystoprostatectomy (RRCP) in a salvage setting for patients with a history of radiation and chemotherapy treatment, complex pelvic anatomy, and significant comorbidities.
Materials and methods: Over a 5-month period, six patients who met these criteria underwent RRCP for urothelial carcinoma. Two of the patients had major cardiovascular disease and were previously denied an open procedure subsequently underwent chemotherapy with external beam radiation protocol. One patient had brachytherapy for prior prostate cancer, and three additional patients had neoadjuvant chemotherapy with large diverticula, measuring up to 12 cm in… More >

Abstract Objective: To examine the usefulness of routine stentograms in patient management following urinary diversion.
Materials and methods: A retrospective review of all patients undergoing urinary diversion from February 2004 to February 2007 was performed. Three hundred twenty-six patients were identified. One hundred fifty patients were excluded: 101 patients had no stentogram and 49 patients had incomplete records or follow up.
Results: Of the 176 patients, ureteral anastomotic leak was detected in three of 344 ureters (0.9%). The ureteral stents were left in situ until the leaks resolved. None of the three developed a ureteral stricture. Ten (3.0%) ureters… More >

Abstract Objective: To determine if adjustment of prostate-specific antigen velocity (PSAV) for variation improves prediction of cancer in men with previous negative prostate biopsy.
Patients and methods: Records of men undergoing prostate biopsy between 1999 and 2004 by a single urologist were reviewed to identify men with at least three follow up PSA measurements. Patients with atypia, high grade prostatic intraepithelial neoplasia or cancer on baseline biopsy were excluded. Men were rebiopsied if perceived to have rising PSA. Men with cancer, no cancer, or no repeat biopsy were compared for PSAV and a new parameter, PSAV%/Variation. PSAV was… More >

Abstract Introduction: Diet has been linked to prostate cancer risk. Dietary modification may inhibit prostate cancer progression.
Materials and methods: As part of a randomized trial, we analyzed the effect of a diet based intervention on 25 prostate cancer patients who had previously undergone surgery or radiation.
Results and conclusions: In the intervention arm, vegetable intake increased (p < 0.05), fat intake decreased (p < 0.05), and mean plasma levels of ß-carotene and total carotenoids increased (p < 0.05). In the control arm, there were no significant changes in diet or blood carotenoids. These data support the feasibility of studying More >

Abstract Purpose: To describe a clinical pilot case of renal lymphoma successfully treated using helical tomotherapy, and to evaluate alternative hypofractionated treatment schedules and their potential applicability to future cases of renal cell carcinoma (RCC).
Patients and methods: An 82-year-old female patient with a large right perinephric mass encircling the lower pole of the right kidney was treated on the Hi-ART unit (TomoTherapy Inc., Madison, WI, USA) with daily pretreatment megavoltage CT imaging. Gross tumor volumes (GTVs) were outlined on every MVCT study. The Planned Adaptive software was used for calculation of dosimetric parameters for both the target… More >

Abstract Objective: To compare kidney oxygenation profiles between partial and complete renal artery clamping during nephron sparing surgery (NSS) in a porcine model.
Materials and methods: Twelve female farm pigs underwent a laparoscopic nephrectomy. Subsequently, an open partial nephrectomy was performed on the remaining kidney using either total (n = 6, TC) or partial (n = 6, PC) clamping of the renal artery. Real time renal partial oxygen pressure (rPO2) was monitored using a Licox probe (Integra, San Diego, CA). Creatinine levels were measured prior to open partial nephrectomy and on POD #3 and #7. The remaining kidney… More >

Abstract Objective: Requests for sperm extraction in terminally ill or recently deceased patients have been increasing with the gained acceptance and success of assisted reproductive techniques such as in vitro fertilization and intracytoplasmic sperm injection. This review aims to outline the many challenges associated with these requests.
Materials and methods: The medical literature surrounding ethical and legal issues of posthumous sperm extraction was examined.
Results: Several issues within the field of sperm extraction in the terminally ill patient and the postmortem patient still arouse a significant amount of debate and controversy. One controversial factor surrounds the issue of consent… More >
