Urinary tract injuries during surgery for placenta accreta spectrum disorders

ObjectiveThe main purpose of this study was to report the incidence of lower urinary tract injuries (UTI) during cesarean section (CS) hysterectomy in cases of Placenta Accreta Spectrum (PAS) disorders.Study designRetrospective analysis including all women with a prenatal diagnosis of PAS between January 2010 and December 2020. A dedicated multidisciplinary team was involved to define a tailored management for each patient. All relevant demographic parameters, risk factors, degree of placental adhesion, type of surgery, complications and operative outcomes were reported. ResultsOne hundred and fifty-six singleton gestations with a prenatal diagnosis PAS were included in the analysis. 32.7% of cases were classified as PAS 1 (grade 1-3a FIGO classification), 20.5% as PAS 2 (grade 3b FIGO classification) and 46.8% as PAS 3 (grade 3c FIGO classification). A CS hysterectomy was performed in all cases. Surgical complication occurred in seventeen cases (0% in PAS 1, 12.5% in PAS 2 cases and in 17.8% in PAS 3). The incidence of UTI in our series was 7.6% in all women with PAS, including 8 cases of bladder and 12 of ureteral lesion, and 13.7 % in those with PAS 3 only. ConclusionDespite advances in prenatal diagnosis and management, surgical complications, mainly those involving the urinary system, still occur in a significant proportion of women undergoing surgery for PAS. The findings from this study highlight the need for a multidisciplinary management of women with PAS in centers with high expertise in prenatal diagnosis and surgical management of these conditions.

Urinary tract injury during hysterectomy: Does surgeon specialty and surgical volume matter?

Ureteral injury is a known complication of hysterectomies. Recent studies have attempted to correlate surgeon volume and experience with incidence of urinary tract injuries during hysterectomies. Some studies have reported that as surgeon volume increases, urinary tract injury rates decrease. To our knowledge, no studies have assessed the relationship between surgeon subspecialty and the rate of urinary tract injury rates during minimally invasive hysterectomy. To determine the incidence of urinary tract injury between urogynecologists, gynecologic oncologists, and general gynecologists. The study took place from January 1, 2016 to December 1, 2021 at a large community hospital in Detroit, Michigan. We conducted a retrospective chart review of adult patients who underwent minimally invasive hysterectomy. After we identified eligible patients, the surgeon subspecialty was identified and the surgeon's volume per year was calculated. Patient demographics, medical history, physician-dictated operative reports, and all hospital visits postoperatively were reviewed. Urologic injury occurred in four patients (2%) in the general gynecologist group, in one patient (1%) in the gynecologic oncologist group, and in one patient (1%) in the urogynecologist group. When comparing high and low-volume surgeons, there was no statistically significant difference in urinary tract injury (1% vs 2%) or bowel injury (1% vs 0%). There were more complications in the low-volume group vs the high-volume group excluding urinary tract, bowel, or major vessel injury. High-volume surgeons had four (1%) patients with a complication and low-volume surgeons had 12 (4%) patients with a complication (P = 0.04). Our study demonstrated that there was no difference in the urinary tract injury rate in general gynecologists vs subspecialists, however our study was underpowered.

Detection rate with routine postoperative renal ultrasound to identify urinary tract injury after gynecological surgery

The aim of this study was to establish the rate at which routine postoperative renal ultrasonography is able to detect urinary tract injury following gynecological surgery. A retrospective analysis was carried out for the study period 2015-2019 of all patients who had undergone subtotal or total hysterectomy, or radical hysterectomy or salpingectomy, salpingo-oophorectomy, or oophorectomy, and subsequently had a urinary tract injury. In a total of 2068 patients, 25 urinary tract injuries occurred (1.21%), including 21 urinary bladder lesions (1.02%) and four ureteral injuries (0.19%). The incidence of urinary tract injuries was 3% in oncologic procedures and 0.86% in procedures for benign disease. Nineteen injuries (76%) were diagnosed intraoperatively, and six injuries (24%) were clinically diagnosed after surgery. All of the patients had uneventful postoperative renal ultrasound examinations. Routine postoperative renal ultrasonography was not capable of diagnosing urinary tract injuries after gynecologic surgery. Routine postoperative renal ultrasound examinations should, therefore, not be performed after gynecologic operations.

Judgment and Prevention of Urinary Tract Injury in Gynecological Surgery Based on Data Mining.

In this paper, a data mining-enabled model is developed to analyze the case-related data of 39 patients with urinary tract injury who underwent laparoscopic surgery in a certain hospital from 2012 to 2017. Statistics on the history and characteristics of the case data summarized and analyzed the causes of urinary tract injury and the urinary system. The relationship between the occurrence of injury and the type of surgery and the treatment and preventive measures taken for urinary tract injury during and after surgery are summarized. The statistical method with SPSS16.0 statistical software was used to analyze the data of this study, and the X2 test was used to compare the rates. The differences of P ≤ 0.05 and P ≤ 0.01 were statistically significant. Laparoscopic surgery in gynecology is a minimally invasive technique, but it is still accompanied by the possibility of complications. During the experimental setup and implementation, we have observed that among 8742 cases of laparoscopic surgery complicated by urinary tract injury, there were 39 cases with a rate of 0.45%. In the past five years, the incidence of urinary tract injury in gynecological surgery in our country has increased year by year, and the number of cases of urinary tract injury has also increased year by year. Through analysis, it is found that the cause of the injury is related to the level of surgery, pelvic adhesion, and energy equipment. Based on the above problems, according to the clinical data of patients with urinary tract injury complicated by gynecological surgery in the hospital, the relevant factors of gynecological surgery complicated by urinary tract injury are analyzed to improve the awareness of urinary tract protection and prevention of injury during the operation and preventive measures are actively taken to avoid medical treatment.

Incidence of urinary tract injury while performing total laparoscopic hysterectomy and role of cystoscopy

Introduction: Total laparoscopic hysterectomy is a common surgical procedure performed by a gynaecological endoscopic surgeon. Urinary tract injuries, though rare, is a serious complication requiring early detection and management. The aim of this study is to determine the incidence and risk factors for injury to the lower urinary tract during total laparoscopic hysterectomy and the role of cystoscopy in diagnosing the injury. Materials and Methods: All patients who underwent total laparoscopic hysterectomy for benign disease from January 1, 2017, to November 1, 2019, at the Institute of Kidney Diseases and Research Centre were included. Intraoperative cystoscopy with oral Pyridium given before surgery was routinely performed. Relevant data were abstracted to determine the incidence of lower urinary tract injury, predictors of injury and post-operative complications and the role of cystoscopy. Results: Total laparoscopic hysterectomy was performed in 150 consecutive subjects. Out of the encountered 6 cases (4%) of renal injuries in our study, two (1.3%) cystotomies were noted and repaired. An absent ureteral spill of Pyridium was detected in one subject, ureteral injury that was detected and confirmed with retrograde pyelography and managed with percutaneous nephrostomy and ureteric implantation. Three patients had a ureteric injury which was missed initially with a cystoscope. Later on, the patient presented with a urinary leak. The injury was identified and managed surgically. Only 25% (1/4) of injuries were recognised with the use of cystoscopy with Pyridium. All patients recovered with no long-term complications on follow-up. Conclusions: Renal injuries are relatively uncommon during total laparoscopic hysterectomy. Nevertheless, when an injury does occur, quick recognition of the problem and a working knowledge of its location and treatment are essential in providing patients with optimal medical care. Surgeons should consider performing cystoscopy at the time of total laparoscopic hysterectomy.

Could Bladder Inflation Prior to Cesarean Section Prevent Urinary Tract Injury in High Risk Group? A Randomized Controlled Trial

Background: Accidental urinary tract particularly bladder injury during cesarean delivery has a significant maternal morbidity, as it may lead to extended operative time, infection of urinary tract and sometimes development of urinary tract fistulae. Objective: To find out the efficacy of urinary bladder inflation immediately prior to cesarean section (CS) procedure in minimizing incidence of accidently urinary tract injury in high risk patients. Setting: Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Qena, Egypt. Duration: From August 2017 to November 2018. Study Design: A prospective randomized controlled trial. Methods: Seventy six pregnant women recruited from attendants of outpatient antenatal care unit of obstetrics and gynecology department who planned for cesarean delivery and carried one or more risk factors for urinary tract injury. Patients randomly were classified into 2 groups (group I included 38 cases, underwent bladder inflation using triple way Foley’s catheter immediately before CS and group II included 38 cases, and underwent bladder deflation with 2 ways Foley’s catheter immediately before CS. Results: The overall incidence of urinary tract injury was significantly higher in group II (7 cases = 18.4%) than in group I (2 cases = 5.2%) with p value < 0.001. The incidence of urinary bladder injury was moderately significantly higher in group II (5 cases = 13.1%) than group I (2 cases = 5.2%) with p value < 0.01; ureteric or combined vesico-ureteric injuries had been reported only in group II (1 case = 2.6% and 1 case = 2.6%) respectively with no case reported in group I (p < 0.001). There was a highly statistically significant difference between group I and group II as regard to hospital stay (p < 0.001) but mildly significant differences in operative time and remote urinary tract fistulae (p < 0.05). Conclusions: There was significant reduction in urinary bladder injury, ureteric injury, operative time and hospital stay. Urinary bladder inflation immediately before cesarean section should be applied in patients who have any risk factor of dense bladder adhesion as a protective procedure against urinary tract injuries.

Urinary Tract Injury in Gynecologic Laparoscopy for Benign Indication

To perform a comprehensive literature review of the incidence, location, etiology, timing, management, and long-term sequelae of urinary tract injury in gynecologic laparoscopy for benign indication. A systematic review of PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov was conducted. Four hundred thirty-three studies were screened for inclusion with 136 full-text articles reviewed. Ninety studies published between 1975 and 2015 met inclusion criteria, representing 140,444 surgeries. Articles reporting the incidence of urinary tract injury in gynecologic laparoscopy for benign indication were included. Exclusion criteria comprised malignancy, surgery by urogynecologists, research not in English, and insufficient data. A total of 458 lower urinary tract injuries were reported with an incidence of 0.33% (95% CI 0.30-0.36). Bladder injury (0.24%, 95% CI 0.22-0.27) was overall three times more frequent than ureteral injury (0.08%, 95% CI 0.07-0.10). Laparoscopic hysterectomy not otherwise specified (1.8%, 95% CI 1.2-2.6) and laparoscopically assisted vaginal hysterectomy (1.0%, 95% CI 0.9-1.2) had the highest rates of injury. Most ureteral injuries resulted from electrosurgery (33.3%, 95% CI 24.3-45.8), whereas most bladder injuries resulted from lysis of adhesions (23.3%, 95% CI 18.7-29.0). Ureteral injuries were most often recognized postoperatively (60%, 95% CI 47-76) and were repaired by open ureteral anastomosis (47.4%, 95% CI 36.3-61.9). In contrast, bladder injuries were most often recognized intraoperatively (85%, 95% CI 75-95) and were repaired by laparoscopic suturing (34.9%, 95% CI 29.2-41.7). The incidence of lower urinary tract injury in gynecologic laparoscopy for benign indication remains low at 0.33%. Bladder injury was three times more common than ureteral injury, although ureteral injuries were more often unrecognized intraoperatively and underwent open surgical repair. These risk estimates can assist gynecologic surgeons in effectively counseling their patients preoperatively concerning the risks of lower urinary tract injury.

Urinary tract injuries during cesarean section in patients with morbid placental adherence: retrospective cohort study

Background/objective: The purpose of this study is to evaluate the cases of lower urinary tract injuries during cesarean section with or without hysterectomy in cases with morbid placental adherence.Methods: This record based retrospective study was conducted at Ain Shams University Maternity Hospital in Cairo, Egypt during the period between January 2014 and December 2016. It included all patients who had urinary tract injuries during cesarean section with or without hysterectomy in the cases with morbid placental adherence and they were collected from files of pregnant women who were admitted at hospital planned for termination of pregnancy. Patients were enrolled in four groups, Group 1: cases without urinary tract injuries. Group 2: cases with injuries to the bladder. Group 3: cases with injuries of the ureter. Group 4: cases with injuries to the bladder and ureter.Results: This study gave us new information about the incidence of urinary tract injuries during cesarean section with morbid adherence placenta was 21.7% (Bladder 11.7%, Ureter 4.7%, and bladder with ureter 5.3%). There were various types of repair of urinary tract injury, as the following, bladder repair 10.8%, ureteric catheterization 0.9%, ureterovesical repair or reimplantation 1.5%, bladder repair and ureterovesical 1.2%, bladder repair and ureteric catheterization 2.3%, ureteric catheterization and ureterovesical 1.5 and 6.4% of cases needed urologic consultations. There is a real relation between urinary tract injury and obesity (55.3%). Bladder invasion was found in only 26.9% of all cases according to sonography findings. Most of the cases were delivered by cesarean section in 67.5%, and the remainders were delivered by cesarean hysterectomy 32.5%. About 96.5% of cases needed a blood transfusion.Conclusions: The morbid adherent placenta is still a challenge, which faces us as obstetricians, due to high morbidity and mortality. A multidisciplinary team is mandatory to avoid complications.

Laparoscopic Hysterectomy and Urinary Tract Injury: Experience in a Health Maintenance Organization.

To evaluate the incidence, detection, characteristics, and management of urinary tract injury in a cohort undergoing laparoscopic hysterectomy, and to identify potential risk factors for urinary tract injury with laparoscopic hysterectomy. Retrospective analysis (Canadian Task Force classification II-2). Kaiser Permanente San Diego Medical Center, 2001 to 2012. Women who underwent attempted laparoscopic hysterectomy for benign indications. Total laparoscopic hysterectomy, laparoscopic-assisted vaginal hysterectomy, and laparoscopic supracervical hysterectomy. Demographic and clinical characteristics, surgical techniques, and perioperative complications were abstracted from the medical record. Multivariable logistic regression analysis assessed independent risk factors for ureteral or bladder injury. A total of 3523 patients (mean age, 45.9 ± 8.0 years; median parity, 2; range, 0-10), with a median body mass index (BMI) of 29 kg/m(2) (range, 16-72 kg/m(2)), underwent laparoscopic hysterectomy; 20% had intraoperative cystoscopy. The incidence of urinary tract injury was 1.3% (46 of 3523); of the 46 patients with injuries, 19 (0.54%) had ureteral injuries, 25 (0.71%) had bladder injuries, and 2 (0.06%) had both types. Of the 21 ureteral injuries, 6 (29%) were diagnosed intraoperatively and 15 (71%) were diagnosed postoperatively, including 4 with normal intraoperative cystoscopy. Of the 27 bladder injuries, 23 (85%) were identified intraoperatively. In multivariable logistic analysis, a BMI of 26 to 30 kg/m(2) (compared with >30 kg/m(2)) was associated with an increased risk of ureteral injury, and a BMI ≤25 kg/m(2) (compared with >30 kg/m(2)) and the presence of endometriosis were associated with an increased risk of bladder injury. Urinary tract injury occurred in 1.3% of laparoscopic hysterectomies, with ureteral injuries almost as common as bladder injuries. Normal intraoperative cystoscopy findings did not exclude the presence of ureteral injury.

Urinary tract injuries in laparoscopic gynaecological surgery; prevention, recognition and management

Key content Injury of the urinary tract is the most common major complication of gynaecological laparoscopic surgery. Injury to either bladder or ureter results in significant morbidity for the patient and may lead to litigation. Knowledge of pelvic anatomy, training and meticulous technique are of paramount importance in reducing the incidence of urinary tract injury. Ideally an injury should be identified and repaired during the primary operation, but vigilance in the immediate postoperative period may result in early recognition and intervention. Learning objectives To understand the common risk factors of urinary tract injury at laparoscopy. To learn strategies to prevent injury where possible. To learn strategies for intraoperative and postoperative recognition and repair of such injuries. To understand the significance of multi‐disciplinary management of such injuries. Ethical issues Limited evidence shows that laparoscopic hysterectomy may carry a higher risk of urinary tract injury compared with abdominal hysterectomy. Should patients be counselled accordingly?

Laparoscopic Gynae-oncological Procedures: Lessons Learnt After a Single Institution Audit of Complications and Their Management in 567 Consecutive Patients

To retrospectively evaluate the complications of the laparoscopic pelvic surgeries and to formulate the guidelines to avoid them. Retrospective study (Canadian Classification). Advanced Laparoscopic Institute. Nine hundred and seven operated for gynecological malignancies. Laparoscopic surgeries. 567 women suffering from different pelvic conditions were studied in a period of 60months. The median age of the patient was 35 (11-80). Complications occurred in 32 patients (32/567, 5.5%). The overall incidence of urinary tract injury in all the advanced cases at our institute was 2.1% (12/567). The incidence of bowel injury at our center was 1.76%. The incidence of vascular injury at our institute was 1.76% (10/567). Laparoscopic complications are different than those seen following open surgeries. Anticipation, early recognition, and timely intervention help to reduce morbidity. Laparoscopic management of complications is possible. Formulating standard guidelines can help to avoid many such complications.

Urinary tract injury: medical negligence or unavoidable complication?

The incidence of urinary tract injury is low in most gynaecological operations but, if undiagnosed, is a cause of significant postoperative morbidity for the patient and litigation for the gynaecologist. A Medline search of studies of urinary tract injury at gynaecological surgery show that only one in 10 ureteral injuries and one in three bladder injuries are detected at the time of surgery without intra-operative cystoscopy. As cystoscopy is not routinely performed by the majority of gynaecologists during surgery, even in difficult cases, failure to detect injury to the urinary tract by itself should not be seen as negligence. However, all gynaecologists performing pelvic surgery should be encouraged to become competent in cystourethroscopy and perform this intra-operatively, at least in all high-risk cases of gynaecological surgery.

Urinary Tract Injures: Recognition and Management

Iatrogenic injury to the urinary tract during colorectal surgery can be a source of significant morbidity. Although most cases of ureteral injury occur in patients without significant risk factors, the incidence of urinary tract injuries increases in patients with prior pelvic operations, inflammatory bowel disease, infection, and in patients with extensive neoplasms causing distortion of normal surgical planes. The most commonly injured locations are the ureter, bladder, and urethra. Mechanisms of injury include ligation, transection, devascularization, and energy induced. Early identification of urinary tract injuries is paramount in minimizing morbidity and preservation of renal function. Anatomic considerations for preventing injuries, diagnostic techniques for localizing and staging injuries, as well as reconstructive techniques and principles of repair are discussed.

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.

Urinary tract injury in laparoscopic-assisted vaginal hysterectomy

Study objective To evaluate the incidence and characteristics of urinary tract injury after laparoscopic-assisted vaginal hysterectomy (LAVH). Design A retrospective study that evaluated all cases of urinary tract injury at the time of LAVH in an 11-year period. Parameters including surgical indication, site of injury, time of diagnosis, method of treatment, and long-term follow-up were analyzed. (Canadian Task Force classification II-2). Setting Tertiary care university hospital. Patients A total of 38 urinary tract injuries were found in 7725 LAVH. Intervention LAVH and repair of urinary tract injuries with transvaginal or transabdominal approach. Measurements and main results The incidence of urinary tract injury after LAVH was 4.9/1000 procedures: 3.9/1000 for urinary bladder injury and 1.0/1000 for ureteral injury. Prior cesarean section was the most common risk factor for bladder injuries. Ninety-six percent (29/30) of urinary bladder injuries were detected and treated during surgery. Half (4/8, 50%) of the ureteral injuries were identified during surgery. Of the 38 complications, 28 (75.7%) occurred in surgery. Conclusion Most urinary tract injuries in LAVH were identified during surgery and are associated with the surgeon’s experience. Bladder injury can be repaired either transvaginally or abdominally; ureteral injury can be repaired abdominally.

Urinary tract injuries during pelvic surgery: incidence rates and predisposing factors

To review the cases of urinary tract injury following major pelvic surgery that were treated in our hospital over the last 12 years, in relation to possible predisposing factors and incidence rates of injury arising in various surgical procedures. From 8,824 major gynecological operations performed in our department, 29 cases of intraoperative urinary tract injury were found. Thirty eight patients visited the urology department during the same period for the management of urogenital fistula following pelvic surgery. Parameters that were examined included type of urinary tract injury, indication for surgery, type of operation, coexisting pathological conditions, past history of pelvic surgery or pelvic irradiation, and the delay in the recognition and management of the urinary tract injury. The overall incidence of urinary tract injury in pelvic surgery was 0.33%. The incidence of urinary tract injury in radical hysterectomy was higher than that of total abdominal hysterectomy(0.76 vs 0.26%). Of the intraoperative urinary tract injuries, 48.4% coexisted pelvic pathologies. Of all the cases with urinary tract injury, the most common type of operation was total abdominal hysterectomy (n = 45, 67.2%), and the most common indication was uterine myoma (n = 25, 36.9%). The most common type of urinary tract injury was bladder injury, including bladder laceration and vesicovaginal fistula(n = 57, 76.1%). The frequency of reoperation was found to be lower in patients with a shorter delay in the recognition of the injury (p < 0.05). Possible predisposing factors for urinary tract injury are coexisting pelvic adhesion, distortion of normal pelvic configuration, previous irradiation history, previous operation history, and the extent of surgery. In high-risk patients, proper evaluation is needed to avoid urology complications before operation.

The incidence of urinary tract injury during hysterectomy: A prospective analysis based on universal cystoscopy

To evaluate the incidence of urinary tract injury due to hysterectomy for benign disease. Patients were enrolled prospectively from 3 sites. All patients undergoing abdominal, vaginal, or laparoscopic hysterectomy for benign disease underwent diagnostic cystourethroscopy. Four hundred seventy-one patients participated. Ninety-six percent (24/25) of urinary tract injuries were detected intraoperatively. There were 8 cases of ureteral injury (1.7%) and 17 cases of bladder injury (3.6%). Ureteral injury was associated with concurrent prolapse surgery (7.3% vs 1.2%; P = .025). Bladder injury was associated with concurrent anti-incontinence procedures (12.5% vs 3.1%; P = .049). Abdominal hysterectomy was associated with a higher incidence of ureteral injury (2.2% vs 1.2%) but this was not significant. Only 12.5% of ureteral injuries and 35.3% of bladder injuries were detected before cystoscopy. The incidence of urinary tract injury during hysterectomy is 4.8%. Surgery for prolapse or incontinence increases the risk. Routine use of cystoscopy during hysterectomy should be considered.
