Diagnosis and Therapeutic Management in Kidney, Ureter and Bladder Trauma

Trauma refers to the destruction of tissues or organs by external forces and it is the most common cause of mortality and morbidity in children (1, 2). Injuries of the genitourinary tract may be the result of blunt (falls, sport injuries, motor vehicle accidents and sexual abuse) or penetrating (stab wounds, gun shots, falling onto sharp objects) injuries. The genitourinary tract is significantly injured in 2.9% of paediatric trauma patients 4.In the paediatric population, the kidney is the most affected organ in the genitourinary tract (>60% of all genitourinary tract injuries) 4. Blunt renal trauma is the most common type of injury representing 80-90% 4. The paediatric kidney is more susceptible due to less abdominal and retroperitoneal fat, weaker trunk and abdominal muscles and a lower position in the abdomen. Preexisting renal abnormalities such as UPJ obstruction, hydronephrosis, horseshoe kidney or ectopic kidney make the kidney more vulnerable. Spiral computed tomography is the gold standard method for radiological assessment. Surgical intervention is needed only in the minority of children. Isolated ureteral injury due to trauma is very rare in children. Penetrating ureteral trauma is more common than blunt trauma in the paediatric population. Among all urological trauma cases, the incidence of ureteral injury is lower than 1% [4]. Ureteral injuries include contusion, laceration and avulsion. Because of their hyperextensible vertebral column, children are more likely to sustain deceleration injuries. Delayed films of IVP and CT are the main diagnostic tools whereas the gold standard is retrograde ureteropyelography. Ureteral injury treatment options depend on the location of injury. The bladder in children is a more abdominal organ than in adults. Lying in an exposed position above the pelvis, the bladder is more vulnerable in this age group as it is less well protected due to the less developed abdominal fat and rectus muscles. Here, too, the most common type of trauma is blunt injury. High percentages of bladder injuries are associated with pelvic fractures (70-90%) 4. The average rate of bladder injury in patients with pelvic fractures is 4% in the paediatric age group 4. Conventional or CT cystography is the gold standard method of imaging.

The Retroperitoneal Approach to Endometriosis

Study ObjectiveTo demonstrate principles of laparoscopic management of deeply infiltrating endometriosis requiring retroperitoneal entry. DesignStep-by-step demonstration and explanation of technique using videos from patients with deeply infiltrating stage IV endometriosis who failed medical management (Canadian Task Force classification IIIB). This study was exempt from Institutional Review Board review. SettingLarge academic medical center. InterventionsLaparoscopic surgical excision of endometriosis requiring retroperitoneal dissection. ConclusionSurgical excision of endometriosis is an essential tool for the management of symptomatic disease. Chronic inflammation may lead to distorted anatomy and limit the ability to identify pelvic landmarks, precluding the use of blunt dissection. High surgical morbidity may result from unintentional injury to the ureters or retroperitoneal pelvic vessels. Knowledge of pelvic anatomy defines a safe space for sharp entry into the retroperitoneum, ureterolysis using blunt and sharp dissection, identification of pelvic vasculature, and judicious application of electrosurgery. With appropriate technique, the rate of intraoperative complications, including bowel, bladder, and ureteral injury as well as hematoma and bleeding, is approximately 1%. Postoperative complications, including drop in hemoglobin, urinary retention, cystitis, and abdominal wall hematoma, are usually minor, and reoperation rates are well under 1%. Thorough dissection of the retroperitoneum facilitates complete excision of endometriosis with minimum morbidity.

Abdominal Versus Laparoscopic Sacrocolpopexy: A Systematic Review and Meta-analysis.

Sacrocolpopexy (SC) is considered the criterion-standard treatment for management of vaginal vault prolapse (VVP), and laparoscopic SC (LSC) has become a popular alternative to the abdominal approach. However, there are limited definitive data comparing the 2 procedures. The aim of this meta-analysis is to compare the abdominal sacrocolpopexy (ASC) with the LSC for the management of VVP. Electronic searches of MEDLINE, EMBASE, PubMed, Cochrane Register of Controlled Trials, Cochrane Database of Systematic Reviews, CINAHL, and Google scholar were performed. A systematic review and meta-analysis of studies comparing ASC and LSC for the management of VVP were performed. Seven studies were included with a total of 1461 patients: 589 in the LSC group and 872 in the ASC group. The conversion rate for LSC to ASC was 3% (17 cases). One LSC and 1 ASC were each converted to vaginal procedures. The operative time was significantly greater with LSC (mean difference, 25 minutes; 95% confidence interval [CI], 5.43-45.07 minutes); however, ASC had significantly greater intraoperative blood loss (mean difference, 107 mL; 95% CI, -139.59 to -73.73 mL), longer hospital stay (mean difference, 1.71 days; 95% CI, -2.21 to -1.22 days), and increased risk of postoperative ileus/small bowel obstruction (odds ratio, 2.88; 95% CI, 1.31-6.33). There was no significant difference in rate of bladder injury, bowel injury, mesh exposure, or repeat prolapse surgery. Laparoscopic SC takes longer but is associated with less intraoperative blood loss, shorter hospital stay, and reduced postoperative ileus/small bowel obstruction and hence is a suitable alternative to the abdominal technique.

Bladder injury and success rates following retropubic mid-urethral sling: TVT EXACT™ vs. TVT™

ObjectiveAlthough placement of a retropubic mid-urethral slings (MUS) is one of the gold standard surgical treatments for stress urinary incontinence, new devices are poorly evaluated before marketing. We compared TVT-EXACT™ (TVT-E), a new device expected to reduce bladder injuries, with the historically described bottom-to-top TVT™ (TVT). Study designThis retrospective study compared TVT-E (n=49) and TVT (n=49). The main outcomes were the prevalence of complications (bladder injuries, immediate postoperative pain, perioperative complications, etc.) and the short-term success rate (no reported urinary leakage and negative cough test) of both MUSs. ResultsMinimum follow-up was 12 months. The characteristics of the two groups were comparable. The prevalence of bladder injury for TVT-E and TVT was 8% and 6%, respectively (p=1). The intensity of immediate postoperative pain (VAS/100) was lower following TVT-E than after TVT (8.0 vs. 15.9, p=0.01). The first post-void residual was increased in the TVT-E group (153.9 vs. 78.9mL, p=0.045), and there were more postoperative bladder outlet obstruction (BOO) symptoms in the TVT-E group (24% vs. 6%, p=0.02). However, there was no difference when considering only de novo BOO (14% vs. 4%, p=0.16). The prevalence of peri- and post-operative complications was equal in the two groups. The success rate was similar at 12 months of follow-up (80 vs. 82%, p=1). ConclusionThe prevalence of bladder injury was unchanged with TVT-EXACT™ compared with TVT™, but post-operative pain was decreased. The success rate of both retropubic MUSs was similar at 12 months of follow-up.

Urinary Tract Injury at Benign Gynecologic Surgery and the Role of Cystoscopy: A Systematic Review and Meta-analysis.

To calculate the rates of urinary tract injury detected during and after benign gynecologic surgery. To explore the role of routine intraoperative cystoscopy and determine if it helps in reducing injuries detected postoperatively. We conducted a literature search for urinary tract injuries at benign gynecologic surgery in PubMed, EMBASE, ClinicalTrials.gov, and Web of Science from January 2004 to August 2014. We combined our results with a database from a previously published systematic review to include earlier studies. A total of 79 studies met our inclusion criteria. Excluded were letters to the editor, studies involving only selective cystoscopy in higher risk patients, case reports, and reports that included injuries resulting from obstetric or oncologic procedures. Data from each report were classified according to type of surgery into vaginal hysterectomy, abdominal hysterectomy, laparoscopic hysterectomy, other (nonrobotic) gynecologic and urogynecologic surgery, robotic hysterectomy, and other robotic gynecologic and urogynecologic surgery. We determined the ureteric and bladder injury rates for each surgery type from studies in which routine intraoperative cystoscopy was performed and separately from studies in which it was not performed. Intraoperatively detected rates of ureteric and bladder injury were markedly higher with routine intraoperative cystoscopy. We obtained an adjusted ureteric injury rate of 0.3% and a bladder injury rate of 0.8%. The estimated postoperative ureteric injury detection rates per 1,000 surgeries were 1.6 without routine cystoscopy and 0.7 with routine cystoscopy. Postoperative bladder injury detection rates per 1,000 surgeries were 0.8 without routine cystoscopy and 1.0 with routine cystoscopy. Although routine cystoscopy clearly increases the intraoperative detection rate of urinary tract injuries, this systematic review of 79 mostly retrospective studies shows that it does not appear to have much effect on the postoperative injury detection rate.

Bilateral and Unilateral Total Extraperitoneal Inguinal Hernia Repair (TEP) have Equivalent Early Outcomes: Analysis of 9395 Cases.

IntroductionTo date, no randomized controlled trials have been carried out to compare the perioperative outcome of unilateral and bilateral inguinal hernia repair using an endoscopic technique. In a Swiss registry study comparing unilateral with bilateral inguinal hernias, no further details were given regarding the nature of the intra- and postoperative complications. In addition, some authors have raised the issue of prophylactic repair of a clinically healthy other groin side.Patients and methodsIn the Herniamed Registry, in total 9395 patients with a TEP were enrolled. These comprised 6700 patients with unilateral (71.31 %) and 2695 patients (28.69 %) with bilateral inguinal hernia repair. The outcome variables, analyzed in a multivariable model, were the intra- and postoperative as well as general complication rates, reoperation rate, duration of operation, and length of hospital stay.ResultsWhile no significant difference was found in the overall number of intraoperative complications between the unilateral and bilateral group (p = 0.310), a significantly higher number of urinary bladder injuries in the bilateral TEP operation of 0.28 % compared with 0.04 % for unilateral TEP (p = 0,008) were noted. The greater probability of reoperation (0.82 % for unilateral vs. 1.78 % for bilateral TEP; p < 0,001) in the unadjusted analysis was confirmed in the multivariable model [OR 2.35 (1.504; 3.322); p = 0.001].SummaryA significantly higher intraoperative urinary bladder injury rate and reoperation rate because of postoperative surgical complications constitute a difference in the perioperative outcome between unilateral and bilateral TEP which that warrants attention. Based on these results, prophylactic operation of the healthy other groin should not be recommended.Electronic supplementary materialThe online version of this article (doi:10.1007/s00268-015-3055-z) contains supplementary material, which is available to authorized users.

Incidence of adverse events after uterosacral colpopexy for uterovaginal and posthysterectomy vault prolapse

We sought to describe perioperative and postoperative adverse events associated with uterosacral colpopexy, to describe the rate of recurrent pelvic organ prolapse (POP) associated with uterosacral colpopexy, and to determine whether surgeon technique and suture choice are associated with these rates. This was a retrospective chart review of women who underwent uterosacral colpopexy for POP from January 2006 through December 2011 at a single tertiary care center. The electronic medical record was queried for demographic, intraoperative, and postoperative data. Strict definitions were used for all clinically relevant adverse events. Recurrent POP was defined as the following: symptomatic vaginal bulge, prolapse to or beyond the hymen, or any retreatment forPOP. In all, 983 subjects met study inclusion criteria. The overall adverse event rate was 31.2% (95% confidence interval [CI], 29.2-38.6), which included 20.3% (95% CI, 17.9-23.6) of subjects with postoperative urinary tract infections. Of all adverse events, 3.4% were attributed to a preexisting medical condition, while all other events were ascribed to the surgical intervention. Vaginal hysterectomy, age, and operative time were not significantly associated with any adverse event. The intraoperative bladder injury rate was 1% (95% CI, 0.6-1.9) and there were no intraoperative ureteral injuries; 4.5% (95% CI, 3.4-6.0) of cases were complicated by ureteral kinking requiring suture removal. The rates of pulmonary and cardiac complications were 2.3% (95% CI, 1.6-3.5) and 0.8% (95% CI, 0.4-1.6); and the rates of postoperative ileus and small bowel obstruction were 0.1% (95% CI, 0.02-0.6) and 0.8% (95% CI, 0.4-1.6). The composite recurrent POP rate was 14.4% (95% CI, 12.4-16.8): 10.6% (95% CI, 8.8-12.7) of patients experienced vaginal bulge symptoms, 11% (95% CI, 9.2-13.1) presented with prolapse to or beyond the hymen, and 3.4% (95% CI, 2.4-4.7) required retreatment. Number and type of suture used were not associated with a higher rate of recurrence. Of the subjects who required unilateral removal of sutures to resolve ureteral kinking, 63.6% did not undergo suture replacement; this was not associated with a higher rate of POP recurrence. Perioperative and postoperative complication rates associated with severe morbidity after uterosacral colpopexy appear to be low. Uterosacral colpopexy remains a safe option for the treatment of vaginal vault prolapse.

Hysterectomy in patients with previous cesarean section: comparison between laparoscopic and vaginal approaches

ObjectiveTo evaluate surgery-related outcomes of laparoscopic (LH) and vaginal hysterectomy (VH) in patients with a history of previous cesarean section (CS). Study designData on 289 consecutive patients with a history of CS undergoing VH (n=49, 17%) and LH (n=219, 76%) were collected. Basic descriptive statistics, univariate and multivariate analyses were performed to evaluate surgery-related outcomes. A propensity-matched algorithm was applied in order to reduce allocation biases between groups. ResultsPatients undergoing LH were more likely to have a history of multiple cesarean sections (44% vs. 18%; p=0.001). Additionally, uterine weight was greater among patients undergoing LH than VH (median weight: 235 (range, 45–2830) vs. 150 (range, 40–710)g; p<0.001). Three patients in each group experienced procedural bladder injuries (3/219 (1%) vs. 3/49 (6%); p=0.07; RR: 1.65; 95%CI: 0.74, 3.68). The rate of grade 3 or worse postoperative complications was balanced between LH and VH (1% vs. 0%; p=1.00). Patients undergoing LH experienced a shorter length of hospital stay in comparison to patients undergoing VH (1 vs. 2 days; p=0.02). Considering the overall population, we observed via multivariate analysis that age (OR: 1.003 (95%CI: 1.001, 1.004) per 10-year increase in age; p=0.002), VH (OR: 17.80 (95%CI: 1.762, 180,378); p=0.01) and number of cesarean sections≥2 (OR: 27.70 (95%CI: 1.976, 388,285); p=0.01) increased the risk of developing bladder injuries during hysterectomy. ConclusionsLH is a safe and feasible procedure in patients with previous CS, and it is associated with a low bladder injury rate.

Perioperative adverse events after minimally invasive abdominal sacrocolpopexy

Our first objective was to compare peri- and postoperative adverse events between robotic-assisted laparoscopic sacrocolpopexy (RSC) and conventional laparoscopic sacrocolpopexy (LSC) in a cohort of women who underwent these procedures at a tertiary care center. Our second objective was to explore whether hysterectomy and rectopexy at the time of sacrocolpopexy were associated with these adverse events. This was a retrospective cohort study of women who underwent either RSC or LSC with or without concomitant hysterectomy and/or rectopexy from 2006-2012. Once patients were identified as either having undergone RSC or LSC, the electronic medical record was queried for demographic, peri-, and postoperative data. Four hundred six women met study inclusion criteria. Mean age and body mass index of all the women were 58 ± 10 years and 27.9 ± 4.9 kg/m(2). The women who underwent RSC were older (60 ± 9 vs 57 ± 10 years, respectively; P = .009) and more likely to be postmenopausal (90.9% vs 79.1%, respectively; P = .05). RSC cases were associated with a higher intraoperative bladder injury rate (3.3% vs 0.4%, respectively; P = .04), a higher rate of estimated blood loss of ≥500 mL (2.5% vs 0, respectively; P = .01), and reoperation rate for pelvic organ prolapse (4.9% vs 1.1%, respectively; P = .02) compared with LSC. Concomitant rectopexy was associated with a higher risk of transfusion (2.8% vs 0.3%, respectively; P = .04), pelvic/abdominal abscess formation (11.1% vs 0.8%, respectively; P < .001), and osteomyelitis (5.6% vs 0, respectively; P < .001). The mesh erosion rate for all the women was 2.7% and was not statistically different between LSC and RSC and for patients who underwent concomitant hysterectomy and those who did not. Peri- and postoperative outcomes after RSC and LSC are favorable, with few adverse outcomes. RSC is associated with a higher rate of bladder injury, estimated blood loss ≥500 mL, and reoperation for recurrent pelvic organ prolapse; otherwise, the rate of adverse events is similar between the 2 modalities. Concomitant rectopexy is associated with a higher rate of postoperative abscess and osteomyelitis complications.

Inadvertent cystotomy at laparoscopic hysterectomy - Sydney West Advanced Pelvic Surgery (SWAPS) Unit January 2001 to June 2009

To review the rate of inadvertent cystotomy during laparoscopic hysterectomy performed by the Sydney West Advanced Pelvic Surgery Unit (SWAPS). To compare this rate with other published data. To identify the risk factors for bladder injury at laparoscopic hysterectomy and to review the management and outcome following such injury. This was a retrospective observational study. All hysterectomies where the SWAPS clinical fellow was involved were included. The study period was from January 2001 to June 2009. Simple statistical formulae were used to analyse data in this study. There were 1223 hysterectomies performed during this period. Eighty-one percent of these were performed laparoscopically. There were 14 (1.1%) bladder injuries reported during this period. All bladder injuries occurred in the laparoscopic group. The majority were managed by laparoscopic repair or conservative management (86%). Two cases (14%) were converted to laparotomy. There were no short- or long-term sequelae. With increasing experience, a fall in the incidence of inadvertent cystotomy was noted during the study period. Inadvertent cystotomy is a recognised complication at hysterectomy. The rate in the SWAPS unit is comparable to that of other published series. Overall, there has been a decline in the rate of bladder injury, which appears attributable to more experience gained with an acquisition of increased skill levels and improved techniques.

Obesity and the incidence of bladder injury and urinary retention following tension-free vaginal tape procedure: retrospective cohort study.

Background/Aims. Aim of the study was to establish an effect of obesity on the incidence of bladder injury or urinary retention following tension-free vaginal tape (TVT) procedure. Methods. This was a retrospective cohort study based at the Norfolk and Norwich University Hospital in the UK. Study population included 342 cases of TVT procedures. Incidence of bladder injury was 4.7% (16/342). Rate of urinary retention was 9% (31/342). Body mass index (BMI), age, type of analgesia, concomitant prolapse repair, and previous surgery were factors studied. Univariate analysis was performed to establish a relationship between BMI and complications, followed by a multivariable regression analysis to adjust for age, concomitant surgery, type of analgesia, and previous surgery. Results. Neither univariate analysis nor multivariate regression analysis revealed any statistically significant influence of obesity on the incidence of bladder injury or urinary retention. Unadjusted odds ratios and adjusted odds ratios for bladder injury and urinary retention by BMI groups were OR 1.7296 CI 0.4818–6.2097; OR 1.3745 CI 0.5718–3.3043 and adj. OR 2.885 CI 0.603–13.8; adj. OR 1.299 CI 0.502–3.365. Conclusion. Obesity does not appear to influence the rate of bladder injury or urinary retention following TVT procedure.

Résultats fonctionnels de la chirurgie de l’incontinence urinaire à l’effort par bandelette sous-urétrale par voie rétropubienne et transobturatrice

To compare functional results following retropubic and transobturator mid-urethral sling procedures. Multicenter randomized controlled trial. Power calculation was based on the rate of bladder injury. The current study concerns an analysis of secondary judgment criteria. One hundred and forty-nine patients were randomly allocated to either TVT (n=75) or TVT-O (n=74). Among them, 132 women completed a 24-month follow-up. There was no significant difference between the two groups, concerning urodynamics data (excluding uroflowmetry) at 12 months follow-up, functional and sexual results at 6, 12 and 24 months follow-up. Concerning sexual results, an improvement in visual analogue scale scores was observed in both groups at 24 months follow-up with no difference between the two groups: median score increased from 70 (IQR: 50-80) pre-operatively to 90 (IQR: 70-100) at 24 months follow-up (P=0,0004) in TVT-O group and from 70 (IQR: 50-80) to 85 (IQR: 70-100) (P=0,0009) in TVT group. TVT and TVT-O procedures are both associated with an increase in quality of life with no significant differences in functional results at 2 years follow-up.

Transobturator TVT-O versus retropubic TVT: results of a multicenter randomized controlled trial at 24 months follow-up

The purpose of this study is to compare the retropubic tension-free vaginal tape (TVT) procedure with the inside-out transobturator approach (TVT-O). Multicenter randomized controlled trial. One hundred forty-nine patients were randomly allocated to either TVT (n = 75) or TVT-O (n = 74). Interview, medical examination, pain scores, success rates, and quality of life assessment were recorded pre-operatively, and 2, 6, 12, and 24 months post-operatively. One hundred forty-nine patients underwent surgery, and 132 completed a 24-month follow-up. Bladder injury rate was 5% (4/75) in the TVT group and 2% (2/74) in the TVT-O group (p = 0.68). There was no significant difference between the two groups, concerning overall cure rate and the patients' satisfaction rate at 24 months follow-up. The range of mean pain scores was significantly higher after the TVT-O procedure post-operatively but not at 24 months follow-up. TVT and TVT-O procedures both have an outcome associated with an increase in quality of life with no significant differences in satisfaction rates at 2 years follow-up.

Do the Advantage slings work as well as the tension-free vaginal tapes?

There is currently no data on the safety and efficacy of the Advantage sling despite its widespread use. We compared the efficiency and safety outcome data of 556 tension-free vaginal tape (TVT) and 108 Advantage slings after assessing for potential confounding factors. The two groups proved comparable. Bladder injury rates were 4.6% for the Advantage group and 2.9% for the TVT group (p = 0.36). Subjective stress incontinence cure were 83.3% and 85.3%, respectively (p = 0.66). Incidences of de novo urgency, urge incontinence, and voiding difficulties were 22.2% vs 14.7% (p = 0.06), 9.3% vs 7.4% (p = 0.55), and 11.1% vs 6.7% (p = 0.11), respectively. No major differences between the two slings were observed apart from a non-significant trend towards more de novo urgency and voiding difficulty symptoms with the Advantage group. It may be possible that due to its different biomechanical properties, the Advantage slings should be left looser.

Urethral injury associated with minimally invasive mid‐urethral sling procedures for the treatment of stress urinary incontinence: a case series and systematic literature search

The introduction of the TVT has brought about dramatic changes in our practice as regards surgery for stress urinary incontinence, although the risk of bladder injury has caused concern. The subsequent development of tapes introduced through the obturator foramina may limit the rate of bladder injury, and some have suggested that cystoscopy is no longer required during stress incontinence surgery. Several cases of urethral injury referred to our unit have caused us concern about this approach. We present here brief details of these cases along with a systematic search of the literature on urethral injury following mid-urethral tape procedures.

Urinary Tract Injury During Hysterectomy Based on Universal Cystoscopy

To estimate the incidence and location of injury to the urinary tract during hysterectomy for benign gynecologic disease. This was a prospective clinical study in an academic environment performed at three sites. Diagnostic cystourethroscopy was performed on all patients after hysterectomy for benign disease. Eight hundred thirty-nine patients were enrolled. The incidence of urinary tract injury associated with hysterectomy for benign disease was 4.3% (39 of 839 cases). The rate of bladder injury was 2.9% (24 of 839 cases), and rate of ureteral injury was 1.8% (15 of 839 cases). There were three cases of simultaneous bladder and ureteral injuries, resulting in a cumulative injury rate of 4.3%. The injury detection rate using intraoperative diagnostic cystoscopy was 97.4% (817 of 839 cases). The most common site of injury to the ureter was at the junction of the ureter and the uterine artery in 80% (12 of 15 cases) of ureteral injuries. Transection and kinking injuries were the most frequent type of injury. There were 21 cases of subnormal dye efflux from the ureteral orifices, with no subsequent injury detected on further evaluation. Ureteral injury occurred most commonly at the level of the uterine artery, and transection and kinking injuries were most frequent. Diminished dye efflux from ureteral orifices was not associated with injury. III.

Incidence and risk factors of bladder injuries during laparoscopic hysterectomy indicated for benign uterine pathologies: a 14.5 years experience in a continuous series of 1501 procedures

Laparoscopic hysterectomy is indicated as an alternative to laparotomy when the vaginal route is potentially difficult because of an immobile uterus and a poor vaginal accessibility. The aim of this study was to evaluate the rate, the risk factors for bladder injuries in a series of 1501 laparoscopic hysterectomies indicated for benign uterine pathologies. This study was conducted retrospectively from January 1993 to 2000 and prospectively from 2001 to July 2007.The indications, patients' characteristics and complications were recorded. The overall rate of bladder injuries, the comparison of means (t test) and percentages (exact chi(2) test) between the cases and the population with no injury, the odd ratios (OR) and multivariate analysis were performed using the statistical package for the social sciences software. The rate of bladder injuries was 1% (15 patients). Risks factors were previous Caesarian section [OR: 4.33, 95% confidence interval (CI): 1.53-12.30] and previous laparotomy (OR: 4.69, 95% CI: 1.59-13.8). The rate of injury decreases with the surgeons' experience and reaches a plateau of 0.4% after 100 hysterectomies performed. The rate of bladder injury during total laparoscopic hysterectomy is low and decreases with the surgeon's experience. Bladder injury is not linked to an increase of post-operative morbidity when recognized and repaired during the same laparoscopic procedure. The comparison with other routes of hysterectomies should take into account these risk factors.

Laparoscopic versus open colposuspension for urodynamic stress incontinence

Laparoscopic colposuspension aims to alleviate urodynamic stress incontinence whilst minimizing operative morbidity and mortality.The present study compared laparoscopic to open surgery with regards to short-term outcomes. Meta-analysis of comparative studies published between 1995 and 2006 of laparoscopic versus open colposuspension was performed. End points evaluated were operative outcomes and subjective/objective cure. A random-effect model was used and sensitivity analysis performed to account for bias in patient selection. Sixteen studies matched the selection criteria, reporting on 1,807 patients, of whom 861 (47.6%) underwent laparoscopic and 946 (52.4%) underwent open colposuspension length of hospital stay (WMD = -1.52 days, CI = -2.08, -0.96 days) and return to normal life (WMD = -1.51 weeks, CI = -3.02, 0.01 weeks) were significantly reduced following laparoscopic surgery. These findings remained consistent on sensitivity analysis. Bladder injuries occurred more often in the laparoscopic group (OR = 2.23, CI = 1.11, 4.50), but only with marginal statistical significance. Comparable bladder injury rates were found when studies were matched for quality, year, and randomized trials. Cure rates were similar between the two procedures at 2 years follow-up. Laparoscopic colposuspension results in a significant reduction in hospital stay and earlier return to work, with a possible increased risk of bladder injury. When performed by appropriately experienced surgeons it may be a safe option with advantages for the patient, but further randomized controlled trials should be undertaken to evaluate continence in the longer term at 5 years.
