Care of children with posterior urethral valves after initial endoscopic incision/ablation: what a nephrologist needs to know.

Posterior urethral valves (PUV) are the most common cause of congenital urethral obstruction and are unique in the challenges they pose in management. Endoscopic ablation/incision of the valves is usually offered as the primary treatment of choice. Following this, a range of different clinical patterns are observed, each with varying bladder dysfunction and continence issues and associated with different grades of chronic kidney disease.

Voiding Pressures in Boys: Pdetmax versus PdetQmax - Does it Make a Difference?

Introduction: Invasive urodynamics (UDS) is a standard investigation in children. Studies measuring voiding pressures in children use varied nomenclatures and quote a wide range of voiding pressures. Thus, voiding pressures in children are not considered reliable and they do not find any place in the pediatric diagnostic armamentarium.

Long Tubular Duplication of the Small Intestine - Lessons Learnt from a Common Presentation of a Rare Disease.

Long tubular duplication of the small intestine is one of the most difficult surgical challenges. The presence of heterotopic gastric mucosa necessitates resection of the duplicated bowel, but shared vascularity with the normal adjoining bowel makes the task daunting. We present a case of long tubular small intestinal duplication with certain special surgical and perioperative challenges which were successfully managed.

Urodynamics in Posterior Urethral Valve: Pursuit of prognostication or optimisation.

Introduction: Detrusor dysfunction is known to persist in several patients of Posterior Urethral Valve (PUV) after successful fulguration leading to progressive deterioration of renal function. Persistent bladder outlet obstruction (BOO) in the form of bladder neck hypertrophy, residual valves or strictures may contribute to progressive detrusor dysfunction. These are assessed radiologically or cystoscopically and are managed variedly by anticholinergics, alpha-adrenergic blockers or even bladder neck incision.
