Robotic-assisted pyeloplasty for ureteropelvic junction obstruction

Introduction

We present a case of ureteropelvic junction obstruction secondary to aberrant crossing gonadal vessels in a symptomatic 11-year-old female with horseshoe kidney, treated with a robotic-assisted pyeloplasty.

Diagnostic Evaluation

The patient presented with intermittent right-sided flank pain and vomiting. Renal ultrasound showed right-sided hydronephrosis and an abnormal-shaped kidney. MAG-3 renal scan demonstrated decreased function of the right kidney and no drainage. A MR Urogram showed a horseshoe type kidney with malrotation and an anterior dilated renal pelvis.

Surgical Technique

The patient underwent a robotic-assisted dismembered pyeloplasty. Intraoperatively, the right kidney was confirmed to be malrotated with a large, anteriorly directed renal pelvis. A packet of aberrant crossing gonadal vessels was identified and dissected from the right ureter and surrounding tissue. The ureter was sharply divided at the level of the ureteropelvic junction and transposed above the crossing vessels. A tension free mucosal to mucosal water-tight anastomosis was performed starting at the apex of the incision. A double-J stent was introduced into the ureter. The remainder of the anastomosis was completed with interrupted sutures. There were no intraoperative or postoperative complications.

Conclusions

Robotic-assisted dismembered pyeloplasty is a safe and effective method for UPJO correction in symptomatic patients with complex renal anatomy.
