Abstract available at http://jurology.com/ Editorial Comment: The authors report a series of 455 patients who underwent pyeloplasty, with a 5.9% failure rate. Following initial pyeloplasty, subsequent surgery in 27 patients included endoscopic and open approaches. Of these 27 cases 8 (30%) improved with 1 intervention, while 14 (52%) required 2 interventions and 5 (18%) required 3 interventions. Repeat procedures included Double-JÒ stent insertion (16 cases, with 6% success), endopyelotomy (18, 50%), redo pyeloplasty (12, 92%) and ureterocalycostomy (4, 100%). While less invasive initial procedures are tempting, particularly to salvage an initially unsuccessful surgery, the authors believe that more invasive and definitive procedures “should probably be offered sooner rather than later.” Based on the results presented, I agree.

Abstract available at http://jurology.com/ Editorial Comment: The authors show us that compensatory hypertrophy occurs at about the same rate opposite a multicystic dysplastic or absent kidney as it does opposite a kidney with unilateral renal function less than 10% from hypoplasia, dysplasia or atrophy. These changes occur by 17.5 months. After that renal growth in the better kidney approximates normal renal growth curves. Douglas A. Canning, MD
