Abstract: OBJECTIVE: To compare classical open pyeloplasty with
retroperitoneal laparoscopic pyeloplasty in effectiveness, potential advantages
and complications. MATERIALS AND METHODS: Between March 2006 and April 2010, 113
patients with ureteropelvic junction obstruction underwent retroperitoneal
laparoscopic dismembered pyeloplasty were retrospectively compared with those
of 59 patients who underwent open dismemberse pyeloplasty through a
retroperitoneal flank approach. The Chi-square test was used for statistical
analysis of qualitative data and the Student t-test for analysis of
quantitative data. P < 0.05 was considered significant. RESULTS: Operative time was shorter in the retroperitoneal
laparoscopic group (mean 125 min) compared to the open pyeloplasty group (mean
142 min, P < 0.05). Mean hospital stay was shorter in the retroperitoneal
laparoscopic group (mean 6 days, compared to 9 days, open). Complication rates,
including anastomotic urinary leakage, stenosis and infection, were 4.42% in
retroperitoneoscopic compared to 6.78% open surgery. Anastomotic leakage was 3
cases in the retroperitoneoscopic group versus 1 case in the open group.
Success, defined as improved ultrasonic or renographic parameters, with
resolution of symptoms where discernable, was noted in 98.0% of the open group
and 98.1% of the retroperitoneoscopic group with a mean follow up of 38.4 and
32.7 months, respectively. CONCLUSIONS: Retroperitoneal laparoscopic dismembered pyeloplasty in
treatment of ureteropelvic junction obstruction is a minimally invasive, safe
and effective therapy with short procedure time, less complications, and
shorter convalescence.
