Nephrolithotomy performed concurrently with laparoendoscopic single-site pyeloplasty.

Urology 2014 January
INTRODUCTION: The objective of the present study was to evaluate the results of laparoendoscopic single-site (LESS) pyeloplasty and pyelolithotomy, which were performed concurrently in patients with pelviureteric junction obstruction (PUJO) and renal stones.

TECHNICAL CONSIDERATIONS: Four patients with PUJO and renal stones underwent pyelolithotomy performed concurrently with LESS pyeloplasty. In 3 patients, a 2.5-cm incision was made in the umbilical region. In the fourth patient, the 2.5-cm vertical incision was made at a site 7 cm below the umbilical region because of a stone in the right lower calyx. After dissection of the pelviureteric junction, an incision of approximately 1 cm was made along the presumed transection line of the renal pelvis. The pyelolithotomy was performed using a 24F rigid nephroscope through a SILS port. Dismembered pyeloplasty was performed after extraction of the renal stones was completed. The mean operation time was 277 minutes (range, 225-373), and the mean lithotomy time was 31 minutes (range, 20-50). No intraoperative or postoperative complications were observed. For all 4 patients, discharge from the hospital was possible after a mean of 3.4 postoperative days (range, 3-4). All patients became stone free. Postoperative ultrasound revealed that hydronephrosis improved in all patients. In all patients, resolution of the symptoms was confirmed.

CONCLUSION: LESS nephrolithotomy with pyeloplasty is a safe and effective procedure with a good cosmetic result for patients with PUJO and renal stones.
