Functional outcome after pyeloplasty for unilateral symptomatic XXXX .

@entity1 @entity177 @entity3041
The functional outcome and factors influencing improvement after pyeloplasty for ureteropelvic junction (UPJ) obstruction are still debated. This retrospective study was aimed at evaluating the factors associated with functional improvement in symptomatic unilateral @entity3041 ( @entity3041 ). @entity1 (n = 68) who underwent successful pyeloplasty for unilateral symptomatic UPJ obstruction without any other associated urological abnormality were included. Preoperative evaluation included a diuretic renogram (DR) to confirm obstruction and assess the @entity177 ( @entity177 ). A follow-up DR was obtained 3 months and 1, 2, and 5 years postoperatively. An absolute increase in the differential function of the operated kidney by over 5% was considered significant; such kidneys were classified as improved (group A) and the others as unimproved (group B). The difference between the preoperative and 3-month @entity177 was highly significant (P < 0.001). Significant (P < 0.01) improvement in @entity177 continued until 1 year after pyeloplasty. @entity1 who presented with a mass had significantly greater improvement (P < 0.05) than those who presented with other clinical features. In group A, a significantly higher number of @entity1 presented with a mass. It was also evident that @entity1 aged less than 1 year showed significantly greater (P < 0.01) improvement in @entity177 than older @entity1 . Thus, in unilateral symptomatic @entity3041 with impaired function, @entity1 who present with a mass or those in whom pyeloplasty was performed before 1 year of age showed significantly greater improvement.
