    Input: Objective To compare 1-year cure rates after laparoscopic Burch colposuspension using one double-bite or two single-bite sutures on each side of the urethra . Methods Consecutive women with primary stress urinary incontinence at one university hospital were included . Pre-operative clinical and urodynamic evaluation included cystoscopy , cystouretrometry at rest and stress , and a st and ardized pad test . Immediately before surgery , the patients were r and omized to have one or two polytetrafluoroethylene ( GoreTex CV 2 ; W. L. Gore Inc. , Flagstaff , AZ ) sutures placed on each side of the urethra . During surgery , access to the space of Retzius was achieved by transperitoneal videolaparoscopic technique . Women were scheduled for postoperative interview and pad test 1 year after surgery . Results We included 161 women in the study ; 78 were r and omized to one suture ( group A ) and 83 to two sutures ( group B ) .  Median time for surgery was significantly shorter for group A than for group B ( 60 compared with 77 minutes ; P < .001 ) . We examined 158 women 1 year after surgery , at which time 148 performed a pad test . Objective cure rate was significantly higher in group B than in group A ( 83 % compared with 58 % ; P = .001 ) . Conclusion Two single-bite sutures result ed in a significantly higher objective short-term cure rate than one double-bite suture on each side of the urethra Introduction and hypothesisThe aim of this study is to provide long-term outcome data , at least 10 years , following laparoscopic colposuspension . Methods The study includes a control group who underwent open colposuspension .  A consecutive series of 139 women who had undergone laparoscopic colposuspension were review ed and compared to 52 women who had an open colposuspension in the same unit . Subjects were contacted by telephone , at least 10 years post-operatively , at which time a structured interview was performed which included the short-form Bristol Female Lower Urinary Tract Symptom question naire . Results There was deterioration in subjective cure rates from 71 % and 67 % at 6 months to 52 % and 36 % at 10 years for the laparoscopic and open procedures , respectively . Conclusion This study provides evidence that laparoscopic colposuspension is probably as durable as open colposuspension . However , cure rates for both procedures appear to deteriorate over time , emphasising the importance of long-term follow-up Background The open Burch colposuspension , first described in 1961 had been widely employed for the surgical treatment of women with stress urinary incontinence ( SUI ) caused by urethral hypermobility . We evaluated the long-term efficacy of laparoscopic Burch colposuspension ( LBC )  for SUI in women . Methods A r and omized prospect i ve trial was conducted from September 2010 to January 2013 . The extraperitoneal laparoscopic Burch colposuspension was performed by an operator on 96 women , mean age was 54,3 ± 3,7 years all of whom suffered from SUI or mixed urinary incontinence . Patients completed a self-administered the Short Form-36 ( SF-36 ) , the Physical Component Summary ( PCS ) and Mental Component Summary ( MCS ) , the Short Urinary Distress Inventory ( SUDI ) and Short Incontinence Impact Question naire ( SIIQ ) . at both baseline and follow up(6 weeks , 6 months , 18 months postoperatively ) . The Genito-Urinary Treatment Satisfaction Scale ( GUTSS ) was used to assess satisfaction with surgery . Results After follow up was recorded an improvement of question naries scores . The general health score is improved after surgery ( 2,60 ± 1.02 versus 2,76 ± 1.06 ) with p = 0.09 . The PCS baseline score is 46.29 ± 10.95 versus 49.54 ± 10.41 after treatment with p = 0.01 , so there was a significant baseline to follow up improvement . The MCS improved also , infact baseline score is 42.19 ± 12.57 versus 42.70 ± 13.03 with p = 0.87 . The SUDI baseline score is 50.22 ± 20.73 versus 23.92 ± 17.90 , while SIIQ score is 49.98 ± 23.90 versus 31.40 ± 23.83 with p < 0.01 . In both question naires there is an improvement . Satisfaction with treatment outcomes from the GUTSS at 6-month follow up is 29.5 ± 6.3 with p = 0.46 . Conclusion The LBC has significant advantages , without any apparent compromise in short-term and long term outcomes OBJECTIVE To compare the efficacy , safety , complications , and short-term outcome of laparoscopic and open colposuspension in women with genuine stress incontinence . DESIGN R and omised controlled trial . SETTING Urogynaecology unit in a public hospital , Hong Kong . SUBJECTS AND METHODS Ninety patients with urodynamically proven genuine stress incontinence . Forty-three patients were r and omly allocated to receive open colposuspension and 47 to undergo laparoscopy .  All patients had re assessment within 1 year of the operation . MAIN OUTCOME MEASURES Objective and subjective measures and complication rates . RESULTS There was no significant difference in the duration of stress incontinence , mean preoperative pad test results , or proportion with pre-existing detrusor instability . Among patients in the laparoscopic group , the mean operating time was significantly longer ( 42.0 minutes versus 29.3 minutes ; P<0.0001 ) , while the mean blood loss was significantly less ( 124.7 mL versus 326.9 mL ; P=0.001 ) . Subjective and objective success rates within 1 year were similar for patients in the open and laparoscopic groups ( 86.0 % versus 80.9 % ; P=0.58 , and 86.0 % versus 85.1 % ; P=1.00 , respectively ) . There was no significant difference in the rate of complications , including de novo detrusor instability and an obstructive voiding pattern , enterocele , or dyspareunia . CONCLUSION Laparoscopic colposuspension is a feasible alternative to the open approach . The operating time is longer but the short-term cure rate is comparable with that of the open approach STUDY OBJECTIVE To compare results of laparoscopic Burch colposuspension with those of classic Burch colposuspension , and to assess complications , results , and morbidity associated with each procedure . DESIGN Prospect i ve , r and omized study ( Canadian Task Force classification I ) . SETTING Minimal access surgery unit . PATIENTS Seventy-four women with genuine stress incontinence . INTERVENTION Laparoscopic and classic Burch colposuspensions . MEASUREMENTS AND MEAN RESULTS : Mean operating times for laparoscopic and open surgery were 70.18 + /- 16.54 and 53+/- 10.05 minutes , respectively ( p < 0.001 ) . Mean blood loss was 42.75 + /- 7.2 and 240.5 + /- 35.5 ml , respectively ( p < 0.001 ) . Postoperative analgesia requirement was significantly less with laparoscopy ( p < 0.001 ) . Mean postoperative hospital stay was 36 + /- 6.3 hours for the laparoscopic group and 76+/- 10.4 hours for the open group p<0.001 ) . Average time to return to light work was 8.5 and 31.5 days , respectively . Success rates were 90.9 % at 6 months and 87.9 % at 18 months in the laparoscopic group , compared with 90 % and 85 % , respectively , in the open group . CONCLUSION Given equal efficacy of the two procedures , we prefer the laparoscopic approach since it is associated with lower morbidity , shorter hospital stay , and fewer complications . ( J Am Assoc Gynecol Laparosc 8(1):99 - 106 , 2001 Laparoscopic colposuspension ( LC ) was first described in the early 1990s as a technique distinct from open Burch colposuspension . Subsequently , however , LC was closely modelled along the lines of the Burch technique , and the distinct features of the original urethropexy ( UP ) were largely disregarded . In this case-control series the authors aim ed to compare symptoms and anatomical outcomes after st and ard LC and urethropexy ± paravaginal repair . The design was a clinical retrospective case-control trial . The setting was the urogynaecology and endogynaecology services of tertiary hospitals . Fifty patients after LC and 50 women after UP surgery , matched for age , body mass index , previous surgery , pre-existing urge incontinence and length of follow-up ( 1.01 year , range 0.02–3.54 years ) for LC and 0.98 years ( range 0.06–3.55 years ) for UP ) . Intervention consisted of st and ardised interview and translabial ultrasound imaging . There were no significant differences for subjective cure of stress incontinence ( 80 % for UP vs. 74 % for LC ) , postoperative urge incontinence , frequency and nocturia . Significantly more UP patients complained of voiding dysfunction ( p=0.01 ) . Significant differences were found for urethral rotation , position of the bladder neck on Valsalva and bladder neck descent on Valsalva ( all p<0.001 ) . Both procedures were shown to be effective in curing stress incontinence . The incidence of bladder symptoms was comparable , with the exception of voiding difficulty . Significant differences were observed regarding anatomical appearances , with urethropexies showing more recurrent bladder neck hypermobility and cystocele 
    Output:
    
The study comparing one versus two laparoscopic stitches demonstrated superior results with the latter .
Although there is no robust evidence , when Burch surgery is performed laparoscopically , the use of two stitches seems to be the best option
