Abstract

To elucidate whether dismembered pyeloplasty improves renal function, the authors studied 37 patients with ureteropelvic junction obstruction. Changes in various renal parameters pre-and postoperatively by 99mTc-DTPA diuretic renal scintigraphy(DTPA scan) and intravenous urography were evaluated. Subjects included 24 pediatric(mean age 9.7 years) and 13 adult(mean age 33 years) patients. Postoperative split renal function was improved in 79 % (l9/24) of pediatric patients and in 69%(9/13) of adult ones. While, the excretory slope was improved in 71%(17/24) of pediatric patients and in 77%( 10/13) of adult ones. Hydronephrosis on intravenous urogram was improved in 58% (14/24) and 54% (7/13), respectively between pediatric and adult patients. There was no statistically significant differences of improvement in split renal function and renographic washout curve between pediatric and adult patients. In summary, renal function was improved by dismembered pyeloplasty in both pediatric and adult patients.
