[Extravesical reimplantation of heavily-dilated ureters according to Bradi technique].

INTRODUCTION

Surgery of the ureterovesical anastomoses lesions in case of weakly-dilated ureters is well developed by the Cohen and Lich-Grgoire techniques. However, there are no generally accepted approaches for heavily-dilated ureters. The experience of creating ureterocystoneoanastomosis according to the Bradi technique (1975) for the first time in the literature is presented.

MATERIALS AND

METHODS

The authors modification of the Bradi technique was used in 12 patients of both sexes with a dilated ureters diameter of more than 10 mm. Two cases of refluxogenic and 10 cases of obstructive megaureter were operated on 2010-2019. The follow-up period was 1-10 years. All patients underwent resection of the ureter in width.

RESULTS

No intraoperative complications were noted. One case of acute pyelonephritis with acute urinary retention was noted as postoperative complications. All patients showed a decrease in dilatation of the pyelocaliceal system and ureter according to multispiral computed tomography after 6 months of follow-up. Two patients had vesicoureteral reflux of the first degree. Glomerular filtration rates decreased in 41.7% of cases after 12 months of follow-up. No recurrence of urinary tract infection and stenosis of the anastomosis was detected for 1-10 years monitoring.

CONCLUSION

The Bradi technique along with the Hodgsons ureter reconstruction provides superior results for heavily-dilated ureters in adults.
