To evaluate the effectiveness of laparoscopic repair of primary strictures of ureteropelvic junction (UPJ) depending on baseline renal function of the ipsilateral kidney.The study analyzed results of 134 patients (78 women and 56 men, age from 18 to 56 years) who underwent various types of laparoscopic repair of the UPJ stricture from 2012 to 2015. Depending on the surgical technique all patients were divided into three groups: group 1 (n=34) underwent spiral flap technique by Culp and DeWeerd, group 2 (n=59) - Anderson-Hynes pyeloplasty and group 3 (n=41) had antevasal dismembered pyeloplasty. All interventions ended with internal ureteral stenting for up to 6-8 weeks. Also, all patients were divided into three subgroups, depending on the degree of renal function deficiency - less than 25%, 25-50%, and 51-75%. Treatment effectiveness criteria included the following parameters: complete relief of the pain syndrome, a decrease in the degree of pyeloectasia, stabilization or improvement of the functional state of the renal parenchyma (according to radioisotope renography), and the absence of recurrence of the UPJ stricture.The overall effectiveness of UPJ laparoscopic reconstruction was 94.7% (127 of 134). The effectiveness of the treatment was independent of the surgical technique, the initial thickness of the renal parenchyma and the degree of PCS dilatation. There was an inverse correlation between the treatment effectiveness the degree of kidney function deficiency.In patients with hydronephrosis secondary to UPJ stricture, the effectiveness of surgical treatment is mainly determined by its timeliness. The best treatment results were observed in patients with better renal function. The degree of renal function deficiency should be considered the main prognostic factor for the effectiveness of the forthcoming operation. |
