Hypoandrogenism is Prevalent in Males With Urethral Stricture Disease and is Associated with Longer Strictures.

Objective: To assess the association of hypoandrogenism (HA) with urethral stricture disease in a series of patients undergoing urethroplasty at 2 institutions. HA has recently been associated with increased urethral atrophy in artificial sphincter failures and decreased androgen receptors and periurethral vascularity. HA might be an etiologic factor in urethral stricture disease.

Overactive bladder and autonomic dysfunction: Lower urinary tract symptoms in females with postural tachycardia syndrome.

Aims: Postural Tachycardia Syndrome (POTS) represents an autonomic disorder predominantly affecting females between 15 and 50 years of age. POTS is a chronic disorder (>6 months) characterized by an excessive heart rate increment on standing (>30 beats/min) in the presence of characteristic symptoms of cerebral hypoperfusion or sympathetic activation. Patients have clinically been noted to describe lower urinary tract symptoms (LUTS), although urologic symptoms have not been methodically assessed in the POTS population.

Analysis of patient and technical factors associated with midurethral sling mesh exposure and perforation.

Objectives: To evaluate the technical and patient characteristics associated with the development of mesh perforation and exposure in patients after midurethral sling surgeries.

Methods: After a retrospective review of referred patients, the risk of mesh perforation of the urinary tract over exposure in the vagina was analyzed with multivariate logistic regression, adjusting for the possible predictors of age, body mass index, smoking status at the time of mesh placement, presence of diabetes, type of sling placed, type of surgeon and trocar injury at the time of mesh placement.

Results: A total of 77 women were identified, 27 with mesh perforation and 50 with mesh exposure.

Difference between urethral circumference and artificial urinary sphincter cuff size, and its effect on postoperative incontinence.

Purpose: We assessed whether a difference between intraoperative urethral circumference and artificial urinary sphincter cuff size affects postoperative outcomes.

Materials And Methods: We evaluated the medical records of 87 males who underwent implantation of an artificial urinary sphincter between January 2006 and May 2010. A validated questionnaire was completed by 59 patients for long-term followup.

Interobserver variability when employing the IUGA/ICS classification system for complications related to prostheses and grafts in female pelvic floor surgery.

Introduction And Hypothesis: To unify and organize reporting, an International Urogynecological Association (IUGA)/International Continence Society (ICS) expert consortium published terminology guidelines with a classification system for complications related to implants used in female pelvic surgery. We hypothesize that the complexity of the codification system may be a hindrance to precision, especially with decreasing levels of postgraduate expertise.

Methods: Residents, fellows, and attending physicians were asked to code seven test cases taken from published literature.

Obturator foramen dissection for excision of symptomatic transobturator mesh.

Purpose: Groin pain after transobturator synthetic mesh placement can be recalcitrant to conservative therapy and ultimately requires surgical excision. We describe our experiences with and technique of obturator foramen dissection for mesh excision.

Materials And Methods: The records of 8 patients treated from 2005 to 2010, were reviewed.

Antegrade balloon occlusion of inferior vena cava during thrombectomy for renal cell carcinoma.

Nephrectomy with inferior vena cava (IVC) thrombectomy for advanced renal cell carcinoma (RCC) is a challenging and morbid surgical case. We describe the use of a simple endoluminal technique to occlude the suprahepatic IVC during thrombectomy. A 60-year-old male presented with a large right-sided RCC and IVC tumour thrombus.

Pediatric urolithiasis: experience at a tertiary care pediatric hospital.

Objective: We aimed to determine the epidemiology, risk factors, clinical characteristics, evaluation and course of patients with urolithiasis at the Children's Hospital of Eastern Ontario to improve current diagnostic and management strategies.

Methods: This was a retrospective study of children with newly identified urolithiasis between Jan. 1, 1999, and July 31, 2004.
