Case Overview

This case revolves around a pediatric patient who underwent a reconstructive urologic procedure due to a proximal ureter obstruction, which led to severe hydronephrosis. A pyeloplasty was performed, and a stent was placed to alleviate the condition. However, despite the removal of the indwelling stent post-procedure, the obstruction persisted, as did the hydronephrosis.

The child was subsequently evaluated by another urologist and had to undergo a second pyeloplasty to correct the issues arising from the initial surgical intervention. This case study seeks an expert opinion on pediatric urology standards of care.

Questions to the expert and their responses


How often do you surgically manage pediatric patients that require a pyeloplasty?

As a high-volume pediatric urologist, I frequently perform pyeloplasty on my patients.


Please describe your familiarity with dismembered pyeloplasty procedures.

Most of the procedures I perform are dismembered pyeloplasty. However, I am familiar with multiple approaches and have executed several of them during my practice.


How may a posterior (behind obstructing vessels) pyeloplasty result in recurrent obstructions?

During any pyeloplasty operation, it is crucial to identify blood vessels accurately. If these vessels are missed or not properly managed during surgery, it can lead to recurrent obstructions. In my experience, I have treated patients who faced recurring issues due to these overlooked vessels.


Have you ever reviewed a similar case? If yes, please elaborate.

While I have dealt with many patients experiencing recurrent issues after pyeloplasty and have reviewed multiple legal matters, I have not reviewed a legal case similar to this one. However, I am eager to learn more about this case and discuss it further.
