ABSTRACT
Objective To introduce a new trocar position in the posterior laparoscopic for the treatment of retrocaval ureter.Methods From August 2011 to October 2014,5 cases with retrocaval ureter treated with posterior laparoscopic were retrospectively analyzed,including 3 males and 2 females,aged from 15 to 46 years(mean 34 years).The history of disease ranged from 1 to 10 months,with 3 cases presented with low back pain,and 2 cases being detected uronephrosis by check-up.Results All the operations were successfully completed,with the operation duration ranged from 75-125 min (mean 90min),and blood loss ranged from 20ml to 50 ml(mean 35 ml).The average hospital stay was 6 days(5-7d).There was no wound infection or urine leakage.Ureteral double-J tubes were removed 4 weeks after surgery.Postoperative followup ranged from 2 weeks to 6 months (mean 30 months).There was no anastomotic stricture,and the hydronephrosis relieved.Conclusions Trocar position adjustment of posterior laparoscopic in treatment of retrocaval ureter is convenient to operate,which also shortened the time of operation,reduced the difficulty of operation and the surgeons' fatigue.
