Extraperitoneal laparoscopic dismembered pyeloplasty is capable of addressing all causes of ureteropelvic junction obstruction with excellent functional results and low morbidity, and with an operative time similar to that of open pyeloplasty. Secondary laparoscopic pyeloplasty does not increase hospitalization, conversion or complication rates.

their procedure done or supervised by the same surgeon. RESULTSThe patients' prostate-specific antigen level, Gleason score, clinical stage and prostate weight were similar. The mean values for patients deemed not obese and obese were: for operative duration (182 and 197 min, P = 0.01), blood loss (310 and 250 mL, P = 0.66), hospital stay (3.0 and 3.3 nights, P = 1.00), complications (3.5% and 4.6%, P = 0.77), positive margins (15.4% and 20.6%, P = 0.26) and biochemical recurrence (3.8% and 3.7%, P = 1.00) at a mean followup of 9.7 and 12.0 months, respectively. CONCLUSIONThe operation was significantly longer for obese patients, by a mean of 15 min; all other variables were comparable in the two groups. The results from this study suggest that obese patients can expect a similar outcome to their non-obese counterparts after LRP, when operated on by an experienced surgeon.
