a 40-year - old female patient underwent total abdominal hysterectomy with bilateral salphingo - oopherectomy for dub with right - side broad ligament fibroid . urogram revealed an urinary column up to the lower ureters . the patient was preoperatively dialyzed and biochemical parameters came down to near normal . the patient was placed in a supine position four days after abdominal hysterectomy . a 10 mm infraumbical port was placed along with two 5 mm ports , 4 cm below and lateral to the umbilicus . a 6-fr dj stent ( bard , karlsruhe , germany ) was introduced through cystoscopy and guided into the right renal pelvis under laparoscopic guidance . the left lower ureter was found to be ligated and transected 5 cm above the vesicoureteric junction . the flap was converted into a tube and the lower end of the ureter was anastomosed to the end of the boari flap tube . urine output rose to 3400 cc in the first 24 hrs , serum creatinine came down to 0.9 mg% within 48 hrs , and ultrasound revealed no more hydrouretheronephrosis . in gynecologic surgery , there is always the possibility that ureteral injuries will occur intraoperatively . traditionally , these injuries were treated by laparotomy and ureteroneocystostomy . when the ureter is too short to reach the bladder without tension , bladder flap ( boari ) technique is useful for ureteroneocystostomy . attempts at laparoscopic ureteral reimplantation have involved the extravesical lich - gregoir technique with variable success i. ehrlich and colleagues ( 1994 ) and reddy and evans ( 1994 ) independently showed the safety and feasibility of this technique clinically . in a recent series , lakshamanan and fung ( 2000 ) reported 71 laparoscopic extravesical reimplantations , including 23 unilateral and 24 bilateral , with no persistent reflux or obstruction postoperatively . fergany and colleagues ( 2001 ) reported their experience with laparoscopic bladder flap ( boari ) ureteroneocystostomy in the porcine model . we have successfully used bladder flap ( boari ) ureteroneocystostomy to bridge the gap in lower ureter and maintain the continuity of the draining system .
iatrogenic ureteric injuries in gynecologic surgery are quite common . 
 the laparoscopic spectra of treatment gives a wide range of application . 
 we present the case of a 40-year - old female who underwent total abdominal hysterectomy with bilateral salpingo - oopherectomy for dysfunctional uterine bleeding . 
 postoperatively , she had oliguria with raised creatinine and was found to have ureteric narrowing on magnetic resonance urogram . 
 the patient was successfully managed by laparoscopic ( boari flap ) ureteroneocystostomy .
