The Success of Pyeloplasty in Adult Patients with Ureteropelvic Junction Obstruction: A Retrospective Clinical Study

Objective: Ureteropelvic junction obstruction (UPJO) is a disease often diagnosed in childhood, but it can rarely be detected adults. Dismembered pyeloplasty the gold standard treatment method. In this study, we evaluated success of adult patients with UPJO. Material and Methods: We retrospectively reviewed data who underwent between January 2012 July 2021. Preoperative postoperative differential renal function (DRF), time required for clearance half radioisotope from pelvis (T1/2), presence symptoms, degree hydronephrosis, anteroposterior (AP) diameter pelvis, parenchymal thickness were compared. Results: A total 30 mean age 32.43±7.18 included study. No statistically significant difference was preoperative DRF (37.6±12.08 38±11.35, respectively) (p=0.775). 19 (63.33%) remained unchanged. 7 (23.33%) improved, 4 (13.34%) deteriorated. The AP grade hydronephrosis significantly improved after pyeloplasty. ratio T1/2>20 minutes decreased 83.33% to 26.67% (p=0.001). Before operation 26 (86.67%) symptomatic. After only 8 (26.67%) This change Conclusion: There improvements T1/2, hydronephrosis. Renal preserved surgery. Also, effective pain relief should recommended adults
