Simultaneous laparoscopic surgery for ureteropelvic junction obstruction and retrograde intrarenal surgery for nephrolithiasis

Abstract

Objective: To determine the surgical possibilities of the one-stage laparoscopic repair in the obstructed ureteropelvic junction (UPJ) complicated with nephrolithiasis in combination with the retrograde intrarenal surgery. Case report: The patient A., a 36-year-old male complaining about dragging pains in the right lumbar region was admitted to Urology Unit No. 1 of Krasnodar Regional Clinical Hospital No. 2. The patient underwent ultrasound examination, CT, and dynamic renal scintigraphy. The findings were as follows: the enlargement of pelvicalyceal system in the right kidney (calyx up to 22 mm, pelvis up to 50 mm), 5 calyx concrements and 2 pelvic concrements 6 to 8 mm in size, obstruction at the level of the right UPJ up to 10 mm in length, III grade hydronephrosis on the right according to Lopatkin classification. Conclusions: The combination of laparoscopic surgery and retrograde intrarenal surgery with the flexible ureteroscope and holmium laser is an effective and safe method for the treatment of UPJ obstruction complicated with nephrolithiasis.
