Abstract:
Objective To compare the efficacies of mini-incision dismembered pyeloplasty assisted by retroperitoneal laparoscopy and routine retroperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction(UPJ) obstruction.MethodsThe clinical data of 47 patients with UPJ obstruction,who underwent dismembered pyeloplasty from January 2004 to November 2006 in our hospital,were retrospectively analyzed.Of the patients,22 were treated by mini-incision dismembered pyeloplasty assisted by retroperitoneal laparoscopy(group A),in whom a 4-cm incision was made under the costal margin at the posterior axillary line;and the other 25 cases underwent retroperitoneal laparoscopic dismembered pyeloplasty(group B).The clinical data of the two groups,including the operation time,blood loss,average airway resistance and partial pressure of carbon dioxide,recovery of intestinal function,length of drainage and hospital stay,incidence of urinary leakage,and remission rate of hydronephrosis and improvement of GFR,were statistical analyzed by SPSS 13.0.ResultsNo intra-operative complications occurred in either group.Compared with Group B,Group A had shorter operation time [(92.9?16.3) min vs(155.8?18.6) min,t=-12.251,P=0.000],more blood loss [(18.9?6.3) ml vs(13.6?6.7)ml,t=2.782,P=0.008],lower average airway resistance [(15.6?2.6) cm H2O vs(26.9?4.3) cm H2O,t=-10.715,P=0.000] and partial pressure of carbon dioxide [(36.0?6.9) cm H2O vs(51.6?6.7) cm H2O,t=-7.855,P=0.000].No statistical differences were detected in the recovery of intestinal function,postoperative length of drainage and hospital stay,incidence of urinary leakage,and remission rate of hydronephrosis and improvement of GFR.ConclusionMini-incision dismembered pyeloplasty assisted by retroperitoneal laparoscopy is a safe,effective,and minimally invasive therapy for UPJ obstruction.
