The Diagnostic Accuracy of Transvaginal Ultrasound for Detection of Ureteral Involvement in Deep Infiltrating Endometriosis: A Systematic Review and Meta-Analysis. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2024; 43:7-19. [PMID: 37792527 DOI: 10.1002/jum.16335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 08/28/2023] [Accepted: 09/03/2023] [Indexed: 10/06/2023]
Abstract
OBJECTIVE The aim of this study is to determine the accuracy of transvaginal ultrasound (TVU) for the diagnosis of ureteral involvement in women with deep infiltrating endometriosis (DIE). METHODS The meta-analysis included primary studies comparing the use of TVU for diagnosing endometriotic involvement of the ureter, using laparoscopic surgery and histological diagnosis as the reference standard. Search was performed in several databases (Scopus, Web of Science, and PubMed/MEDLINE). The studies' quality and bias risk were assessed using the Quality Assessment of Diagnostic Accuracy Study-2 (QUADAS-2). Diagnostic performance was estimated by assessing pooled sensitivity and specificity. RESULTS A total of 496 citations were found. Six articles were ultimately selected for this systematic review and meta-analysis after the inclusion and exclusion criteria were applied. Pooled sensitivity and specificity were 0.81 (95% CI: 0.42-0.96), 1.00 (95% CI: 0.93-1.00). The heterogeneity observed was high for both sensitivity and specificity. Overall risk of bias was low. CONCLUSION TVU is a valuable tool for the pre-operative identification of ureteral involvement by DIE.

Laparoscopic ureteroneocystostomy and round ligament bladder hitching for ureteral stenosis in parametrial deep endometriosis: Our tips for a tension-free anastomosis. Int J Gynaecol Obstet 2023; 160:563-570. [PMID: 35965391 DOI: 10.1002/ijgo.14402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 07/20/2022] [Accepted: 08/09/2022] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To investigate the feasibility and the efficacy of laparoscopic ureteroneocystostomy with round ligament bladder hitching. METHODS This is a monocentric retrospective study. Enrolled patients affected by deep endometriosis underwent laparoscopic nerve-sparing parametrectomy and monolateral ureteroneocystostomy with bladder suspension to the round ligament. Perioperative and postoperative outcomes were collected, as well as urinary and pain symptoms before and after surgery. RESULTS Laparoscopic ureteroneocystostomy with round ligament bladder hitching was performed in nine women. The most frequent postoperative complication was post-voiding urinary retention (22.2%). No ureteral fistula or stenosis of the anastomosis was reported. CONCLUSION In selected cases of ureteral resection and reimplantation, performing a round ligament bladder hitching allowed us to overcome the ureteral gap. This is a safe and feasible procedure to ensure stability of the anastomosis and avoid the possible disadvantages of the "standard" psoas hitch procedure.

Expert opinion on the use of transvaginal sonography for presurgical staging and classification of endometriosis. Arch Gynecol Obstet 2023; 307:5-19. [PMID: 36367580 PMCID: PMC9837004 DOI: 10.1007/s00404-022-06766-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Accepted: 08/19/2022] [Indexed: 11/13/2022]
Abstract
Gynecological ultrasonography plays a central role in the management of endometriosis. The rapid technical development as well as the currently increasing evidence for non-invasive diagnostic methods require an updated compilation of recommendations for the use of ultrasound in the management of endometriosis. The present work aims to highlight the accuracy of sonography for diagnosing and classifying endometriosis and will formulate the present list of key messages and recommendations. This paper aims to demonstrate the accuracy of TVS in the diagnosis and classification of endometriosis and to discuss the clinical applications and consequences of TVS findings for indication, surgical planning and assessment of associated risk factors. (1) Sophisticated ultrasound is the primary imaging modality recommended for suspected endometriosis. The examination procedure should be performed according to the IDEA Consensus. (2) Surgical intervention to confirm the diagnosis alone is not recommended. A preoperative imaging procedure with TVS and/or MRI is strongly recommended. (3) Ultrasound examination does not allow the definitive exclusion of endometriosis. (4) The examination is primarily transvaginal and should always be combined with a speculum and a bimanual examination. (5) Additional transabdominal ultrasonography may enhance the accuracy of the examination in case of extra pelvic disease, extensive findings or limited transvaginal access. (6) Sonographic assessment of both kidneys is mandatory when deep endometriosis (DE) and endometrioma are suspected. (7) Endometriomas are well defined by sonographic criteria. When evaluating the ovaries, the use of IOTA criteria is recommended. (8) The description of sonographic findings of deep endometriosis should be systematically recorded and performed using IDEA terminology. (9) Adenomyosis uteri has sonographically well-defined criteria (MUSA) that allow for detection with high sensitivity and specificity. MRI is not superior to differentiated skilled ultrasonography. (10) Classification of the extent of findings should be done according to the #Enzian classification. The current data situation proves the best possible prediction of the intraoperative situs of endometriosis (exclusive peritoneum) for the non-invasive application of the #Enzian classification. (11) Transvaginal sonographic examination by an experienced examiner is not inferior to MRI diagnostics regarding sensitivity and specificity in the prediction of the extent of deep endometriosis. (12) The major advantage of non-invasive imaging and classification of endometriosis is the differentiated planning or possible avoidance of surgical interventions. The recommendations represent the opinion of experts in the field of non-invasive and invasive diagnostics as well as therapy of endometriosis. They were developed with the participation of the following national and international societies: DEGUM, ÖGUM, SGUM, SEF, AGEM/DGGG, and EEL.

Accuracy of transvaginal ultrasound and magnetic resonance imaging for diagnosis of deep endometriosis in bladder and ureter: a meta-analysis. J OBSTET GYNAECOL 2022; 42:2272-2281. [PMID: 35421318 DOI: 10.1080/01443615.2022.2040965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/18/2022]
Abstract
This meta-analysis aimed to determine the accuracy of transvaginal ultrasound (TVS) and pelvic magnetic resonance imaging (MRI) in diagnosing urinary tract endometriosis (UTE). A comprehensive search of the Pubmed and Embase was conducted between January 1989 and June 2020. Studies that described the accuracy of MRI or TVS for the diagnosis of UTE using surgical data as the reference standard were included. Of the 913 citations identified, 23 studies were analysed. For detection of endometriosis in bladder endometriosis (BE), the overall pooled sensitivities of TVS and MRI were 72% and 68% respectively, and their specificities were 99% and 100% respectively. For detection of endometriosis in the ureteral endometriosis (UE), the overall pooled sensitivities of TVS and MRI were 97% and 87% respectively, and their specificities were both 100%. In conclusion, both TVS and MRI provide good accuracy with specific strong points in diagnosing UTE and seem useful first-line methods from a clinical perspective. Besides, pelvic MRI and TVS are more accurate for predicting UTE localised in the ureter than bladder, especially in terms of sensitivity.IMPACT STATEMENTWhat is already known on this subject? Previous studies have confirmed high diagnostic value of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) on bladder endometriosis (BE) respectively. However, high heterogeneity was found for both sensitivity and specificity and no meta-analysis has yet been performed to test the diagnostic value of TVS and MRI for ureteral endometriosis (UE).What the results of this study add? In this meta-analysis, we firstly confirmed high diagnostic value of TVS and MRI on UE respectively. For detection of UE, the overall pooled sensitivities of TVS and MRI were 97% and 87% respectively, and their specificities were both 100%.What the implications are of these findings for clinical practice and/or further research? Early preoperative diagnosis and accurate understanding of the widespread distribution of endometriosis are prerequisites for radical surgical in UTE. In the present study, we updated the previous results on the accuracy of TVS and MRI for the diagnosis of BE and firstly confirmed high diagnostic value of TVS and MRI on UE. Both TVS and MRI provide good accuracy with specific strong points in diagnosing UTE and seem useful first-line methods from a clinical perspective.

Abstract
STUDY OBJECTIVE To investigate the short-term outcomes of laparoscopic ureteroneocystostomy in patients with ureteral endometriosis (UE). DESIGN Retrospective cohort study of consecutive patients who underwent surgery for the ureter endometriosis with hydronephrosis. SETTING A private hospital that provide primary, secondary and tertiary care. PATIENTS 30 consecutive patients with UE who underwent laparoscopic ureteroneocystostomy at our institution between May 2008 and April 2020. INTERVENTIONS Laparoscopic ureteroneocystostomy, if necessary, hysterectomy, salpingo-oophorectomy, cystectomy, partial bladder resection, or partial bowel resection were performed. MEASUREMENTS AND MAIN RESULTS The most common chief complaint was pelvic pain (40%). Endometriosis affected only the left ureter in 56.7% of patients, only the right ureter in 33.3%, and both ureters in 6.7%. Involvement of the ipsilateral ovary was confirmed in 64.3%. The most frequent location of UE was 1-3 cm above the UVJ (46.7%). A psoas hitch was performed in 7 patients (23.3%), and the Boari flap was used in 9 patients (30%). Hysterectomy was performed in 12 patients (40%), and 6 of them had a concomitant bilateral salpingo-oophorectomy (20%). In addition, 3 patients (10%) underwent partial bowel resection, and 2 patients (6.7%) underwent partial bladder resection. After surgery, 24 of 27 patients (80.0%) were free of sever hydronephrosis after surgery. Hydronephrosis recurred in a single patient (3.3%), but the grade of hydronephrosis improved significantly after surgery (P < 0.001). At 6 months of follow up, 4 patients (13.3%) experienced urinary tract infections and 2 patients (6.7%) reported dysuria. Patients reported a regression of dysmenorrhea symptoms (P < 0.001). CONCLUSION This study shows that ureteroneocystostomy provides good results in terms of relapses and symptom control in patients with ureteral endometriosis.

Ureteral endometriosis, the hidden enemy: multivariable fractional polynomial approach for evaluation of preoperative risk factors in the absence of ureteral dilation. Fertil Steril 2021; 116:470-477. [PMID: 33962769 DOI: 10.1016/j.fertnstert.2021.03.027] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 03/17/2021] [Accepted: 03/17/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To determine whether it is possible to predict the risk of ureteral endometriosis (UE) using a mathematical model based on preoperative findings. DESIGN Prospective observational study conducted between January 2017 and April 2020. SETTING Tertiary-level academic referral center. PATIENT(S) Three hundred consecutive women of reproductive age with a diagnosis of posterior deep infiltrating endometriosis (DIE) scheduled for laparoscopic surgery. INTERVENTION(S) Before surgery, anamnestic data and the severity of endometriosis-related symptoms were evaluated, and all patients underwent a complete gynecological examination. Transvaginal and transabdominal ultrasound were performed to map the endometriotic lesion. Ureteral involvement was surgically and histologically confirmed. MAIN OUTCOME MEASURE(S) To select important risk factors for UE and determine a suitable functional form for continuous predictors, we used the multivariable fractional polynomial. RESULTS UE was surgically found in 145 women (48.3%). Based on our multivariable polynomial mathematical model, UE was significantly associated with adenomyosis, parametrial involvement, and previous surgery for endometriosis. A posterior DIE nodule with a transverse diameter >1.8 cm was associated with a higher probability of ureteral involvement. CONCLUSIONS Posterior DIE nodule with a transverse diameter >1.8 cm, adenomyosis, parametrial involvement, and previous surgery for endometriosis appear to be good predictors of UE.

Fernandes LFC, Ebaid GX, Bassi MA. Bilateral ureteral endometriosis-an indolent, aggressive, and dangerous condition. Fertil Steril 2020; 115:256-258.

Abstract
OBJECTIVE To describe an unusual bilateral ureteral reimplantation due to endometriosis and to provide a flowchart of conservative decision making. DESIGN Video description of a case, demonstrating a step-by-step explanation of the decision planning and description of the surgical steps in a female patient with bilateral ureteral endometriosis who had previously undergone operation for bowel endometriosis, and who presented with extensive disease in the posterior compartment with no symptoms besides bilateral renal function disruption. The study was reviewed and approved by the Hospital Beneficência Portuguesa de São Paulo Institutional Review Board. SETTING Tertiary referral center. PATIENTS Deep infiltrating endometriosis involving the ureter has an incidence of 0.1% to 1%, normally affecting the lower one-third of its segment, up to 4 cm above the vesicoureteric junction. Bilateral ureteral involvement occurs in 9% of cases. The absence of specific symptoms makes the diagnosis of this condition challenging. Lumbar pain develops when its involvement is complicated by marked obstruction with impaired renal function. Decompressive surgery is mandatory. The necessity of ureteroneocystostomy increases along with the severity of hydronephrosis, accounting for 62% of ureteral decompressive procedures. However, bilateral ureteroneocystostomy is a rare procedure, not exceeding 6% of ureteral reimplantations. This case illustrates a situation in which a patient with a previous bowel segmental resection presented with an advanced bilateral posterior deep infiltrating endometriosis, compromising the lower rectum below the previous anastomosis, vagina, posterior, and lateral parametrium bilaterally and both inferior hypogastric plexi. Hormonal therapy improved endometriosis symptoms but did not control the urinary tract involvement. Along with the patient, considering a high probability of intestinal, urinary, and sexual impairment, a conservative approach was chosen. INTERVENTION The procedure started with adesiolysis, accessing the retroperitoneum and identifying both dilated ureters (Figs. 1 and 2). They were dissected as caudally as possible, until endometriosis fibrosis was reached, to have a bigger length of proximal ureter to allow a tension-free ureteroneocystostomy. The Retzius space was developed, and the bladder was freed and mobilized (Fig. 3). After cutting the ureter, the proximal end was spatulated. The bladder dome was approximated to the psoas muscle with an interrupted suture to permit a tension-free ureteroneocystostomy. The detrusor muscle was opened for approximately 2 to 3 cm, exposing the vesical mucosa, which was subsequently opened. The posterior ureterovesical anastomosis was performed with running monofilament absorbable 4-0 sutures. A double-J stent was placed, and the anterior ureterovesical anastomosis was completed. The detrusor muscle was loosely closed over the ureter with interrupted absorbable sutures to avoid urinary reflux. A Maryland clamp was used to ensure sufficient entry of the tunnel. All these steps were repeated in the contralateral side. MAIN OUTCOME MEASURE(S) Successful performance of a bilateral laparoscopy tension-free ureteroneocystostomy with bilateral psoas hitch. RESULTS The postoperative course was uneventful. Renal function was restored. One year after surgery, the patient remained asymptomatic, and endometriotic lesions showed no increase, thus remaining stable. CONCLUSION Ureteral endometriosis can be aggressive and indolent. Decompressive procedures must be performed. The decision-making process must take into consideration the patient's characteristics and expectations. In selected cases, a conservative approach may be required, when future possible functional disfunctions can be worse than the actual symptoms. In those situations, close surveillance is necessary.

Abstract
Introduction: The purpose of this study was to review operative management of endometriosis involving the ureter. Materials and methods: Retrospective case series of three patients undergoing resection of ureteral endometriosis with ureteroureterostomy for endometriosis involving the ureter by minimally invasive gynecologic surgeons between 2007 and 2018 at a large academic medical center in the Northeastern United States. A literature review was conducted to find cases with a similar approach. Results: Three cases of ureteral endometriosis surgically managed at our institution with ureteroureteral anastomosis were identified. Ureteral endometriosis was identified preoperatively by hydroureteronephrosis on imaging. Intrinsic ureteral endometriosis was confirmed by pathology in two cases; extrinsic endometriosis was grossly visualized in one case. Operative times ranged from 300 to 387 min. Estimated blood loss ranged from 150 to 250 mL. There were no intraoperative complications. A total of 151 cases with a similar approach were described in the literature. Recurrence of obstructive uropathy occurred in 11 cases. Conclusion: Ureteral endometriosis is a rare complication with several management options. Ureterectomy with ureteroureterostomy has been described in the literature and in three cases at our institution with low complication rates and rare stricture formation. This technique can be successful in the management of ureteral endometriosis and warrants further investigation.

Abstract
Primary ureteral endometriosis is considered to be an uncommon form with an incidence of less than 0.1% in endometriosis. We reported a case of retroperitoneal endometrioid carcinoma possibly arising from ureteral endometriosis. A 52-year-old woman complained left backache. A solid mass in left retroperitoneal cavity with hydronephrosis was found. Diagnostic laparotomy with bilateral salpingo-oophorectomy and biopsy of the mass were performed. Although the primary lesion was not defined in the surgery, the histopathological diagnosis of specimen was endometrioid carcinoma. In the interval debulking surgery after the chemotherapy, tumor adjacent the left iliac vessels was observed. We resected the mass together with 5 cm left ureter and performed ureterectomy and anastomosis. The patient was diagnosed as the malignant transformation of ureteral endometriosis. Adjuvant chemotherapy is now undergoing. In case of finding the cancer tissue in women, we should take into account the malignant transformation of less common endometriosis, including ureteral endometriosis.

Abstract
BACKGROUND The ureter is the second most common site affected by urinary tract endometriosis, after the bladder. Optimal strategies in the diagnosis and treatment of ureteral endometriosis (UE) are not yet well defined. OBJECTIVE AND RATIONALE The aim of this study was to systematically review evidence regarding the epidemiology, pathophysiology, diagnosis, medical and surgical treatment, impact on fertility and risk of malignant transformation of UE. SEARCH METHODS A systematic literature review, by searching the MEDLINE and PUBMED database until April 2018, was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement and was registered in the PROSPERO registry (www.crd.york.ac.uk/PROSPERO CRD42017060065). A total of 67 articles were selected to be included in this review. OUTCOMES The involvement of the ureter by endometriosis is often asymptomatic or leads to non-specific symptoms. When the diagnosis is delayed, UE may lead to persistent hydronephrosis and eventually loss of renal function. Ultrasonography is the first-line technique for the assessment of UE; alternatively, magnetic resonance imaging provides an evaluation of ureteral type involvement. The surgical treatment of UE aims to relieve ureteral obstruction and avoid disease recurrence. It includes conservative ureterolysis or radical approaches, such as ureterectomy with end-to-end anastomosis or ureteroneocystostomy performed in relation to the type of ureteral involvement. Fertility and pregnancy outcomes are in line with those observed after surgical treatment of deep infiltrating endometriosis (DIE). Current evidence does not support the potential risk of malignant transformation of UE. WIDER IMPLICATIONS In this article, we review available evidence on ureteral endometriosis, providing a useful tool to guide physicians in the management of this disease. Diagnosis and management of UE remain a challenge. In relation to the degree of ureteral involvement and the association with other DIE implants, the surgical approach should be planned and carried out in an interdisciplinary collaboration between gynecologist and urologist.
