Rare Case of Bladder Endometriosis in a Post-hysterectomy Patient

Bladder endometriosis, a rare but well-known condition with a high risk of morbidity, affects the bladder. A 43-year-old woman presented with a history of recurrent cyclical discomfort during urination. The patient had undergone a non descent vaginal hysterectomy to address the same symptom. Upon examination, a nodule was discovered between the bladder and vaginal vault. The diagnosis of bladder endometriosis was confirmed through cystoscopy and an Magnetic Resonance Imaging (MRI). The nodule was removed via transurethal resection, and histology confirmed it as endometriosis. After 12 months of follow-up, the patient's postoperative symptoms had completely resolved. Hormonal therapy was initiated, and there were no residual urinary symptoms, chronic pain, or cyclical pain. Women reporting urinary symptoms, particularly those with a history of pelvic surgery, should undergo evaluation for bladder endometriosis. The diagnosis of bladder endometriosis should be considered in women experiencing dysuria and bladder discomfort. A high index of suspicion is required to establish the diagnosis.

Ultrasonographic 3D Evaluation in the Diagnosis of Bladder Endometriosis: A Prospective Comparative Diagnostic Accuracy Study

Objective: The use of three-dimensional (3D) transvaginal ultrasonography (TVS) has been investigated for the diagnosis of deep endometriosis (DE). This study aimed to evaluate if 3D reconstructions improve the performance of TVS) in assessing the presence and characteristics of bladder endometriosis (BE). Design: This was a single-center comparative diagnostic accuracy study. Participants/Materials, Setting, Methods: Patients referred to our institution (Piazza della Vittoria 14 Srl, Genova, Italy) with clinical suspicion of DE were included. In case of surgery, women underwent systematic preoperative ultrasonographic imaging; an experienced sonographer performed a conventional TVS; another experienced sonographer, blinded to results of the previous exam, performed TVS, with the addition of 3D modality. The presence and characteristics of BE nodules were described in accord with International DE Analysis group consensus. Ultrasound data were compared with surgical and histological results. Results: Overall, BE was intraoperatively found in 34 out of 194 women who underwent surgery for DE (17.5%; 95% confidence interval: 12.8–23.5%). TVS without and with 3D reconstructions were able to detect endometriotic BE in 82.2% (n = 28/34) and 85.3% (n = 29/34) of the cases (p = 0.125). Both the exams similarly estimated the largest diameter of BE (p = 0.652) and the distance between the endometriotic nodule and the closest ureteral meatus (p = 0.341). However, TVS with 3D reconstructions was more precise in estimating the volume of BE (p = 0.031). In one case (2.9%), TVS without and with 3D reconstructions detected the infiltration of the intramural ureter, which was confirmed at surgery and required laparoscopic ureterovesical reimplantation. Limitations: The extensive experience of the gynecologists performing the ultrasonographic scans, the lack of prestudy power analysis, and the population selected, which may have been influenced by the position of the institution as a referral center specialized in the treatment of severe endometriosis, are limitations of the current study. Conclusion: Our results demonstrated the high accuracy of ultrasound for diagnosing BE. The addition of 3D reconstructions does not improve the performance of TVS in diagnosing the presence and characteristics of BE. However, the volume of BE may be more precisely assessed by 3D ultrasound.

Laparoscopic Findings Associated with Bladder Endometriosis Are Correlated with Disease Severity.

Bladder involvement is rare in endometriosis. The prevalence is estimated to be ∼1% in patients with endometriosis. However, this figure seems to be an underestimation. The diagnosis of bladder endometriosis might be missed during laparoscopy. The aim of this study was to determine an intraoperative visual score of pelvic lesions that help the surgeon suspect bladder endometriosis. Design, Design Classification: A retrospective analysis was performed on the intraoperative photographs and videos of 69 patients with histological confirmation of bladder endometriosis. A tertiary referral center. Sixty-nine patients with bladder endometriosis were operated on in our center over a 9-year period. Evaluation and analysis of intraoperative laparoscopic findings. We found three subtypes of laparoscopic findings that can assist with diagnosing bladder endometriosis. The most prominent sign was named "kissing round ligaments" (Type K), in which the right and left round ligaments appear closer to each other than usual or even touching one another. This sign is strongly associated with full-thickness invasion of the bladder. Other laparoscopic findings that indicated bladder endometriosis were anatomical distortion (Type A) and proximal occlusion of the tubes (Type B). We further define a scoring system for the lesion that correlates with the severity of the bladder endometriosis from superficial lesions to full thickness. Bladder endometriosis is a rare condition and often remains undiagnosed. Indeed, even during surgery, bladder endometriosis can be missed if the operator is not aware of the suggestive signs. Operative laparoscopic findings may help the surgeon to diagnose bladder endometriosis, and these signs correlate with the severity of the disease.

Urinary tract endometriosis: A case report

Endometriosis affecting the urinary tract is rare and when involved it predominantly affects the bladder, followed by the ureter. The diagnosis of bladder endometriosis is difficult because of its varied clinical presentation. Here we report a case of bladder endometriosis, which was suspected pre-operatively and was confirmed after the histo pathological examination of the excised tissue.

Pre-operative assessment of bladder endometriosis.

The aim of our study was to verify the reliability of transvaginal ultrasonography in the pre-operative evaluation of bladder endometriosis. Six patients with suspected bladder endometriosis were studied. At referral to our department all six women underwent magnetic resonance imaging (MRI), transabdominal and transvaginal ultrasonography, cystoscopy and descending urography. Subsequently all the women underwent transperitoneal cystotomy and excision of endometriotic lesion at laparotomy. In three patients the bladder endometriotic lesions were continuous with adenomyosis in the anterior uterine wall. Histological examination confirmed the endometriotic nature of bladder nodule in all cases. Abdominal ultrasonography visualized the detrusor neoformation in all the patients but was less precise than transvaginal ultrasonography and MRI in defining the size of the lesions, infiltration of the detrusor and continuity with extravesical lesions. Transvaginal ultrasonography was more accurate and versatile than abdominal ultrasonography. The better image resolution allowed an accurate structural analysis of the bladder wall lesion. Furthermore, involvement of the uterovesical septum could be evaluated and adjacent myometrial infiltration recognized. MRI, although very precise, was less versatile than transvaginal ultrasonography and less accurate in establishing the margins of the lesions as perilesional fibrosis is visualized less clearly than areas containing haematic material. Urography was aspecific but still useful to evaluate the integrity of the upper urinary tract and ureters. In conclusion, in our patients transvaginal ultrasonography was found to be the most accurate technique in the diagnosis of bladder endometriosis.
