Abstract

Objective To assess the perioperative complications and functional midterm outcomes after pyeloplasty for poorly functioning kidneys due to ureteropelvic junction obstruction. Patients and Methods We retrospectively analyzed patients who underwent pyeloplasty for primary ureteropelvic junction obstruction in very poorly functioning kidneys in terms of split renal function of ≤20% or estimated glomerular filteration rate of ≤20 mL/minute. Perioperative complications and postoperative outcomes in terms of symptomatic improvement and functional stabilization or recovery were assessed. Results A total of 32 patients with estimated glomerular filteration rate ≤20 mL/minute or split function ≤20% underwent pyeloplasty since January 2010. All patients were followed for a mean period of 26.8 months and none required reintervention for obstructive drainage, deteriorating function, or intractable pain. One patient had persistent pain requiring analgesics and overall success rate (defined as nonobstructive pattern, no deterioration in split function, and no persistent symptoms) was 93.7%. Thirteen patients (40.6%) showed significant improvement in renal function (>5% over preoperative), and in all except 1 (3.1%) case there was no further deterioration of function. Conclusion Pyeloplasty provides high rates of morphological and functional success even in very poorly functioning renal units. There is a possibility of functional recovery in one-third of patients, and in most of the rest, there is no further deterioration.
