Abstract

Purpose: Due to the data paucity about the functional outcomes post pyeloplasty for patients diagnosed with ureteropelvic junction obstruction (UPJO) with a preoperative age above the age of 45 years and according to the elderly definition (age ≥ 65 years), we conducted this study to clarify the different outcomes in adults presented with late hydronephrosis.

Methods: We included patients who were managed by pyeloplasty with a preoperative age ≥ 45 years. We further subdivided those patients into; group (A) patient's age ≥ 65 years and group (B) patient's age ≥ 45 and < 65 years. Split renal function (SRF) difference was evaluated by the changes between the last follow-up and the baseline renogram, where 5% change was considered a significant change. Functional outcomes and factors predicting the functional recoverability post pyeloplasty were evaluated.

Results: A total of 119 patients were included. The mean age was 62.3 ± 16.4 years. Group (A) and group (B) included 47 and 72 patients, respectively. After 24 months, GFR and SRF were increased at the last follow-up (P = 0.32 and 0.57, respectively). No significant functional changes were noted between both groups. Sixty two, 7 and 13 patients showed static, decreased and improved renal function. Lower preoperative SRF was the only predictor for poor functional recoverability in patients with age ≥ 45 years who were managed by pyeloplasty.

Conclusion: Elderly patients should not be excluded from the corrective surgery for UPJO. Lower preoperative SRF was the only predictor for renal function deterioration post pyeloplasty.
