OBJECTIVES We describe a technique for bulbar urethral reconstruction using a combined dorsal plus ventral double buccal mucosa graft (BMG). METHODS From March 2002 to June 2006, 48 men, mean age 35 yr, with bulbar strictures underwent patch urethroplasty using a dorsal plus a ventral double BMG. Average stricture length was 3.65 cm (range: 2-10 cm). The(More)
PURPOSE Learning laparoscopic urethrovesical anastomosis is a crucial step in laparoscopic radical prostatectomy. Previously we noted that practice on a low fidelity urethrovesical model was more effective for trainees than basic suturing drills on a foam pad when learning laparoscopic urethrovesical anastomosis skills. We evaluated learner transfer of(More)
BACKGROUND Thirty minutes has been considered as the threshold for tolerable warm ischemic time (WIT). Recent reports demonstrate recovery of renal function after longer WIT. We assessed renal histology according to different WIT in a 2-kidney porcine model. METHODS Twelve female pigs were randomized to an open or laparoscopic group. Each pig was further(More)
OBJECTIVES To study the safety, feasibility and efficacy of tubeless simultaneous bilateral percutaneous nephrolithotomy. METHODS We retrospectively studied 85 patients who underwent tubeless simultaneous bilateral percutaneous nephrolithotomy in the Department of Urology, Kasturba Medical College, Manipal, Karnataka, India, from July 2006 to June 2013.(More)
The mechanism of proteinuria in many common kidney diseases involves glomerular hemodynamic effects and local expression of angiogenic, fibrogenic, and vasoactive factors. Transforming growth factor (TGF)-β has been associated with many diseases involving proteinuria and renal fibrosis. TGF-β has been shown to induce podocyte dedifferentiation in vitro, but(More)

Midurethral placement of tension-free vaginal tapes with a transvaginal route for stress urinary incontinence achieves higher and better long-term success rates than the transobturator route. Bladder perforations are reported more in transvaginal tape (TVT) but incidences of vaginal erosions, extrusion, and groin pain are exceedingly more in TOT groups.(More)
PURPOSE Conventional methods like smear and culture for Mycobacterium tuberculosis are of limited sensitivity and specificity. Histopathological examination (HPE) for the tissues obtained gives inconclusive diagnosis in the absence of caseous necrosis or stained acid-fast bacilli. This study was conducted to determine the utility of tissue PCR for(More)
BACKGROUND Performing a laparoscopic urethrovesical anastomosis (LUA) after a radical prostatectomy is technically challenging for the novice laparoscopic surgeon. We developed a low-fidelity urethrovesical model (UVM) to allow a urologist to practise this critical step. The aim of our study was to compare the effect of task-specific bench model training(More)
