Background: The use of buccal mucosa grafts (BMG) for urethral reconstruction has increased in popularity over the last several decades. Our aim was to describe our institutional experience with and outcomes after BMG urethroplasty.

Methods: We conducted a retrospective cohort study of boys undergoing BMG urethral reconstruction.

Objective: We compared positive surgical margin (PSM) rates for patients with high risk prostate cancer (HRCaP) who underwent open radical retropubic (RRP), robotic (RALP), and laparoscopic (LRP) prostatectomy at a single institution.

Materials And Methods: We performed a retrospective review of our prospectively maintained IRB approved database identifying prostate cancer patients who underwent RRP, RALP, or LRP between January 2000 and March 2010. Patients were considered to have HRCaP if they had biopsy or final pathologic Gleason score ≥ 8, or preoperative PSA ≥ 20, or pathologic stage ≥ T3a.

MicroRNAs (miRNA) are small, noncoding RNAs with important regulatory roles in development, differentiation, cell proliferation, and death as well as the complex process of acquired drug resistance. The goal of this study was to identify specific miRNAs and their potential protein targets that confer acquired resistance to gemcitabine in urothelial carcinoma of the bladder (UCB) cell lines. Gemcitabine-resistant cells were established from 6 cell lines following exposure to escalating concentrations of the drug and by passaging cells in the presence of the drug over a 2- to 3-month period.

Objective: To describe the indications and outcomes of salvage urethral reconstruction using the combination of urethrectomy and buccal graft replacement.

Materials And Methods: We retrospectively identified 91 consecutive patients who had undergone multistage urethral reconstruction from 2003 to 2009. The demographic and surgical outcomes data, including the need for first stage revision, pre- and postoperative urine flow rates, and reconstruction failure was collected for all patients.

Purpose: Ureteral complications of renal transplantation can dramatically impact renal outcomes. We studied whether complications are associated with preexisting genitourinary pathology or transplant using a deceased donor allograft.

Materials And Methods: We retrospectively reviewed all patients undergoing renal transplantation at our institution between 2000 and 2010.

Background And Purpose: Minimally invasive techniques are currently used for numerous urologic procedures, given decreased morbidity and equivalent outcomes to open surgery. There is, however, a relative paucity of data related to robot-assisted ureteral reimplantation (RAUR) in adult patients for benign stricture disease. We sought to determine the periprocedure outcomes of open distal ureteral reimplantation vs RAUR at our institution.
