Recent literature has endorsed favorable outcomes following ABOi kidney transplantation in pediatric population. Nevertheless, reluctance to pursue an ABOi still remains pervasive. This could be ascribed to various legitimate reasons, namely less extensive pediatric ABOi data, technical difficulties encountered during PP, cost restraints, and concerns regarding higher rates of antibody-mediated ...

Rajesh Ahlawat, Gagan Gautam, Rakesh Khera, Vikram B Kaushik, Prasun Ghosh,

<h4>Background and purpose</h4>Despite excellent results, widespread acceptance of the laparoscopic dismembered Anderson-Hynes pyeloplasty (AH) is hampered by its steep learning curve. Laparoscopic nondismembered pyeloplasty techniques, although simpler, have not matched the results of AH. We have been using a technical modification of AH to combine its excellent outcome with technical ... Read more >>
