Robot-assisted laparoscopic pyeloplasty: A retrospective case series review.

Abstract

INTRODUCTION:

Anderson-Hynes pyeloplasty has been gold standard in the management of pelviureteric junction obstruction (PUJO). It has evolved from open to laparoscopic and now robotic surgery. Open surgery has its drawback of long incision and scar mark, significant post-operative pain and long hospital stay. The main limitation of laparoscopic surgery had been the difficulty in endosuturing. Robotic surgery has incorporated the minimal access method of laparoscopy and endowrist movement of open surgery to overcome the challenge of intracorporeal suturing. Here, we present our initial experience of robotic pyeloplasty.

PATIENTS AND METHODS:

A total of 30 patients underwent robot-assisted laparoscopic pyeloplasty (RALP) over 19 months. Diagnosis of PUJO was made by computed tomography urography, diuretic renogram and retrograde pyelogram in selected patients. All patients underwent RALP by colon reflecting approach. Post-operative evaluation was done by DTPA scan at 3- and 6-month follow-up. Data were analysed after a mean follow-up of 11 months.

RESULTS:

The mean operative time was 148 min and the mean hospital stay was 3.5 days. While 93% of the patients showed objective improvement in their drainage pattern on DTPA renogram, 90% of the patients were symptom-free at the end of 6 months.

CONCLUSIONS:

Robotic pyeloplasty is a safe and easily conquerable technique with comparable outcomes in the hands of surgeons who are beginners in this technique.
