Abstract
BACKGROUND AND PURPOSE: Laparoscopic pyeloplasty is now widely practiced in the United Kingdom and considered the gold standard in the treatment of patients with ureteropelvic junction obstruction. The aim of this audit was to determine the national practice and outcomes for this procedure. PATIENTS AND METHODS: The British Association of Urological Surgeons sent out standardized audit proformas in May 2008 to units across the United Kingdom inviting surgeons who were performing laparoscopic pyeloplasties to submit their results over the last 4 years. Data on the presentation, preoperative investigations, intra-perative details, and postoperative follow-up were collected centrally and inserted into a national database for analysis. RESULTS: There were 323 returns from a total of 30 surgeons. At a median follow-up of 4 months (1-24), the overall symptomatic and renographic failure rates were 10.3% and 8.7%, respectively. Mean operative time was 181 minutes (3--425 min); there were 18 (6%) conversions, 33 (10.5%) complications, and one (0.3%) mortality. Surgeons who submitted 10 or more returns had a lower conversion rate than surgeons submitting fewer than 10 (2.9% vs 14.7%). The median hospital stay was 3 days (1-34 d). There was no difference in failure and complication rate for the retroperitoneal and transperitoneal approaches, although the conversion rate was higher with the retroperitoneal approach. CONCLUSIONS: The results show that laparoscopic pyeloplasty, although achieving acceptable outcomes at a national level in the United Kingdom, had areas of practice that could be improved. It highlights the importance of a high-volume practice in achieving optimum results and the potential problems associated with the retroperitoneal approach.
