Laparoscopic pyeloplasty: Initial experience with 3D vision laparoscopy and articulating shears.

Introduction: Laparoscopic reconstructive surgery is associated with a steep learning curve related to the use of two-dimensional (2D) vision and rigid instruments. With the advent of robotic surgery, three-dimensional (3D) vision, and articulated instruments, this learning curve has been facilitated. We present a hybrid alternative to robotic surgery, using laparoscopy with 3D vision and articulated shears.

The role of preoperative prophylactic antibiotics in hypospadias repair.

Introduction: We sought to determine whether the use of preoperative antibiotics is effective in reducing postoperative wound infections and urinary tract infections (UTI) in hypospadias repair.

Methods: We retrospectively reviewed all hypospadias repairs performed at the Montreal Children's Hospital between March 2009 and September 2012. All types of primary hypospadias repairs and redo cases were included.

How do asymptomatic toilet-trained children void following tubularized incised-plate hypospadias repair?

Purpose: : To evaluate the functional outcome in the form of urinary flow rates in asymptomatic children following uncomplicated tubularized incised plate urethroplasty (TIPU) hypospadias repair.

Methods: : We reviewed the records of children who underwent TIPU at our institution between April 1997 and September 2007 and included only asymptomatic toilet-trained children who had an uncomplicated postoperative course and had undergone uroflometry not less than 1 year postoperatively. Unfavourable voiding parameters were either a plateau curve, a peak flow below the 5th percentile range in nomogram or a post-void residual (PVR) more than 20% of the total functional capacity of the bladder.

Dye-assisted lymphatic-sparing laparoscopic varicocelectomy in children.

Introduction: The ideal method for varicocelectomy in children remains controversial. We present our experience with dye-assisted lymphatic-sparing laparoscopic varicocelectomy (LSLV) in children, which overcomes the limitations of previously described techniques.

Materials And Methods: Twenty-five consecutive LSLVs were performed on children with a mean age of 15 years over a 4-year period.

Risk factors for re-operation following tubularized incised plate urethroplasty: a comprehensive analysis.

Objectives: To review our 10-year experience with tubularized incised-plate (TIP) urethroplasty and determine the risk factors for reoperation.

Methods: The hospital records of 391 patients underwent the TIP procedure from April 1997 to September 2007 were reviewed retrospectively. Data were collected with respect to patient demographics, characteristics of the hypospadias malformation, intraoperative factors and postoperative outcome.

Is routine renography required after pyeloplasty?

Purpose: We assessed whether renography should be performed routinely following pyeloplasty.

Materials And Methods: We identified the records of all patients undergoing pyeloplasty at our hospital between 1989 and 2005. Patients were eligible for the study if they had undergone preoperative ultrasound and renal scan, and postoperative ultrasound and renal scan within 3 months and 1 year postoperatively, respectively.

Bilateral testicular microlithiasis: case report and review of the literature.

Testicular microlithiasis is a rare diagnostic entity of unknown etiology and clinical significance. We hereby describe a case of bilateral testicular microlithiasis in a 10 year-old boy with a past history of mumps. Diagnosis was made by ultrasonography.
