RESUMEN

BACKGROUND: A second look trans-urethral resection of the bladder (re-TUR) is recommended after the diagnosis of T1 high grade (T1HG) bladder cancer. Few studies have evaluated the results of re-TUR after a first en bloc resection (EBR) and none of them have specifically reported the pathological results on the field of previous T1 disease. OBJECTIVE: To report the rate of upstaging and the rate of residual disease (RD) on the field of T1HG lesions resected with EBR. MATERIALS AND METHODS: Between 01/2014 and 06/2022, patients from 2 centers who had a re-TUR after an EBR for T1HG urothelial carcinoma were retrospectively included. Primary endpoint was the rate of RD including the rate of upstaging to T2 disease on the scar of the primary resection. Secondary endpoints were the rate of any residual disease outside the field. RESULTS: Seventy-five patients were included. No muscle invasive bladder cancer lesions were found after re-TUR. Among the 16 patients who had a RD, 4 were on the resection scar. All of these lesions were papillary and high grade. RD outside the field of the first EBR was observed in 12 patients. CONCLUSION: After EBR of T1HG disease, none of our patients had an upstaging to MIBC. However, the rate of RD either on and outside the field of the EBR remains quite significant. We suggested that predictive factors of residual papillary disease (number of tumors at the initial TUR and concomitant CIS) might be suitable to select patient who will benefit of the re-TUR.

RESUMEN

OBJECTIVE: The aim of the present study was to illustrate the outcomes of abnormally invasive placenta (AIP) cases managed in three leading centers in Lebanon. METHODS: We conducted a retrospective multicenter cohort study. Patients managed conservatively (cesarean delivery with successful placental separation) or radically (cesarean hysterectomy) were included in the study. Data included patient characteristics, surgical outcomes (blood loss, operative time, transfusion, partial bladder resection), maternal outcomes (death, length of stay, ICU admission, postoperative hemoglobin level) and neonatal outcomes (Apgar score, neonatal weight, admission to neonatal intensive care unit, neonatal death). RESULTS: The study included 189 patients. In the radical treatment subgroup (141/189), patients were para 3 and delivered at 34 4/7 weeks in average, bled 1.5 L and were transfused with three packed red blood cells, with operative time averaging 160 min. A total of 36% were admitted to the ICU and patients stayed on average for 1 week despite partial bladder resection in 19% of cases. Unscheduled radical delivery occurred at a lower gestational age, was associated with more blood loss, higher rate and volume of transfusion, and risk of maternal and neonatal death. In addition, patients delivered in an unscheduled fashion experienced higher rates of partial bladder resection and longer interventions. In the conservative treatment subgroup, on average patients were para 2 and delivered at 36 weeks, bled 800 mL on average with low rates of transfusion (35%) and ICU admission (22.9%). With regard to neonatal outcomes, the average neonatal birth weight was 2.4 kg in the radical subgroup and 2.5 kg in the conservative subgroup. Neonatal death occurred in 5.4% of cases requiring radical management while it occurred in 2% of patients treated conservatively. CONCLUSION: Through their multidisciplinary approach, the three centers demonstrated that management of AIP in Lebanon has led to excellent outcomes with no maternal mortality occurring in scheduled radical treatment. By comparison of the three leading centers, pitfalls in each center were identified and addressed.

RESUMEN

PURPOSE: Performing restaging transurethral bladder resection (reTURB) for high-risk non-muscle invasive bladder cancer (NMIBC) reduces the risk of recurrence and tumour understaging. Management of residual high-grade papillary Ta or T1 after reTURB has changed this last 10years in international recommendations. This study aimed to compare the recurrence free survival according to the different management procedures performed. MATERIALS AND METHODS: Patients who underwent reTURB for initial high-risk NMIBC between 2011 and 2020 were included. Patients with residual high-grade papillary Ta or T1 tumour after reTURB were divided into two groups: BCG instillations upfront versus BCG following a third-look resection (3TURB). Patient and tumour characteristics, BCG instillations, recurrence-free survival were retrospectively analysed. RESULTS: A total of 162 high-risk patients were included. Sixty-one (37.7%) had residual high-grade papillary Ta or T1 at reTURB: 35 (21.6%) had BCG instillations upfront, 18 (11.2%) had a 3TURB and 8 (5%) had other management. The mean follow-up was 34.2weeks±20.2. Recurrence-free survival was significantly better in patients who underwent BCG instillations upfront (P<0.0043). Recurrence after BCG therapy following reTURB was significantly lower in patients with no residual NMIBC at 6 (92.5% vs. 72.4%, P<0.004) and 12months (85% vs. 67.3%, P<0.03). CONCLUSIONS: The efficacy of intravesical BCG is compromised in case of residual tumour following TURB. The role of a 3TURB following a positive reTURB is not yet determined. This study has confirmed that residual tumor following reTURB is a negative predictive factor but could not demonstrate the value of a 3TURB compared to upfront BCG.

RESUMEN

STUDY OBJECTIVE: Assess efficacy, safety, fertility outcomes and recurrence after laparoscopic resection of bladder endometriosis (BE) using a CO2 laser. DESIGN: Retrospective cohort study. SETTINGS: University gynecologic surgery unit, referral center for endometriosis. PATIENTS: A total of 207 women having undergone laparoscopic BE excision between January 1998 and January 2019. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Intra- and postoperative complication rates. Disease recurrence and fertility outcomes in patients with a minimum 1-year follow-up (n = 176) for "isolated" and "non-isolated" BE groups. RESULTS: Forty-three patients presented with isolated BE. Bladder "shaving" without mucosae opening was performed in 50.7% cases. No intraoperative complications were noted. One postoperative grade 3 complication was related to BE excision: a bladder breach requiring closure by repeat laparoscopy. Mean (± SD) follow-up was 7.05 (± 4.65) years. In patients wishing to conceive (n = 132), the total pregnancy rate (PR) was 75% (48.5% spontaneous), 76.19% in the isolated BE group (56.3% spontaneous). Among the 94 patients with previous infertility, 74.5% conceived, 50% spontaneously. No statistical difference was found in PR and need for in vitro fertilization between isolated and nonisolated BE groups. BE recurrence rate was 3.4%. No difference was observed between groups with full-thickness bladder resection (4/88) and shaving (2/88) (p = .406). Age at surgery (hazard ratio 0.91 [0.84-0.98], p = .016) and postoperative pregnancy (hazard ratio 0.07 [0.01-0.91], p = .042) showed influence on disease recurrence. CONCLUSIONS: The study demonstrates that laparoscopic BE removal is feasible with very low complications rates and was associated with high PR (both spontaneous and in vitro fertilization), even in patients with previous infertility. BE recurrence is lower than for other endometriosis locations. Bladder endometriosis; Laparoscopy; Deep infiltrating endometriosis; Fertility; Partial bladder resection.

RESUMEN

A 22-year-old woman presented with a 12-year history of intensifying paroxysms of anxiety, palpitations and recurrent syncope following micturition. The patient was referred to endocrinology upon discovery of hypertension. An extended family history revealed metastatic phaeochromocytoma and paraganglioma in two grand-uncles. Clinical examination revealed hypertension, with a mean 24-hour ambulatory blood pressure of 150/100 mmHg. Supine plasma normetanephrines were markedly elevated with a raised 3-methoxytyramine, while plasma metanephrines were normal. Computed tomography identified a 4.4 cm mass at the right inferolateral margin of the bladder wall. Scintigraphic imaging confirmed unifocal bladder lesion uptake with no additional metastatic lesions. Following pre-operative alpha blockade, the patient underwent a partial cystectomy. Histology confirmed a paraganglioma, and SDHB staining was lost in neoplastic cells consistent with an SDHB-related paraganglioma. Plasma normetanephrine, 3-methoxytyramine and blood pressure returned to normal postoperatively. Genetic screening identified a germline heterozygous SDHB gene variant c.723C>G. Bladder paragangliomas are a rare but important differential to consider when investigating post-micturition syncope. An extended family history should be sought and suspicion for a genetic cause should be raised, especially when the condition presents at a young age. This is the first reported case describing phaeochromocytoma or paraganglioma with the SDHB gene variant c.723C>G. LEARNING POINTS: Bladder paragangliomas are a rare neuroendocrine tumour which should be considered when assessing patients with haematuria and hypertension, headache, palpitations, sweating and facial pallor with micturition.This case highlights the importance of a thorough clinical history with an extended family history and examination in the setting of micturition syncope, which can rarely occur with bladder paraganglioma.Young age at presentation, a family history of phaeochromocytoma and paraganglioma (PPGL), unusual paraganglioma location, mutifocality and aggressive disease should raise the suspicion for a genetic predisposition to PPGL.

RESUMEN

BACKGROUND: Raoultella Planticola is a facultative anaerobic, gram-negative, water- and soil-dwelling rod bacterium rarely reported as a cause of human disease. However, the number of reported R. planticola infections is growing, without a concomitant increase in research on the microbe or its pathogenesis. Previous genomic studies demonstrating genetic similarities between R. planticola and Klebsiella pneumoniae suggest that capsule biosynthesis, mucoid phenotype, biofilm production, and lipopolysaccharide (endotoxin) synthesis may all be potential virulence factors of R. planticola. We present a unique case of R. planticola infection of the biliary tract 5 years after biliary surgery in a patient with no previously documented risk factors. We also use in silico techniques to predict virulence factors of R. planticola. CASE PRESENTATION: This case report is the first to discuss a R. planticola infection in the biliary tract of late onset post-surgery (5 years) in a Caucasian patient with no previously documented risk factors. CONCLUSIONS: An in-depth search of the current literature did not yield other similar cases of R. planticola infections. Moreover, to the best of our knowledge, our case is the first case of R. planticola isolated from post-endoscopic retrograde cholangiopancreatography (ERCP) as part of biliary sepsis not associated with gastroenteritis. The late onset of the infection in our patient and the results of the in silico analysis suggest that R. planticola may have survived exposure to the host immune system through the creation of an intracellular biofilm or in a non-culturable but viable state (NCBV) for the 5-year period. The in silico analysis also suggests that biofilms, enterobactin, and mucoid phenotype may play a role in the pathogenesis of R. planticola. However, further research is needed to illuminate the significance of pili, capsule biosynthesis, and lipopolysaccharide (LPS) in the virulence of R. planticola. Lastly, as our patient did not have any risk factors previously associated with R. planticola, we suggest that biliary tract stricture, cholecystitis, and prior surgery may be possible novel risk factors.

RESUMEN

PURPOSE: Photodynamic diagnosis using hexaminolevulinate (HAL)-guided BL-TURB may reduce the recurrence risk in non-muscle invasive BCa compared to standard WL-TURB due to more sensitive tumor detection. The impact of the initial use of WL- vs. BL-TURB on follow-up costs was evaluated in this real-world data analysis. METHODS: Anonymous claims data of German statutory health insurances (GKV) from 2011 to 2016 were analyzed in a primary and adjusted study population. Selection criteria included five quarters before enrolment, one index quarter (InQ) of initial TURB and BCa diagnosis, either within two years for the primary analysis or within four years for the adjusted analysis, and a follow-up period (FU) of either eleven or three quarters, respectively. RESULTS: In the primary analysis (n = 2331), cystectomy was identified as an important cost driver masking potential differences between cohorts. Therefore, patients undergoing cystectomy (InQ + FU) were excluded from the adjusted study population of n = 4541 patients (WL: 79%; BL: 21%). Mean total costs of BL-TURB were initially comparable to WL-TURB (WL: EUR 4534 vs. BL: EUR 4543) and tended to be lower compared to WL-TURB in the first two quarters of FU. After one year (3rd FU quarter), costs equalized. Considering total FU, mean costs of BL-TURB were significantly lower compared to WL-TURB (WL: EUR 7073 vs BL: EUR 6431; p = 0.045). CONCLUSION: This retrospective analysis of healthcare claims data highlights the comparability of costs between BL-TURB and WL-TURB.

RESUMEN

OBJECTIVE: To demonstrate a robotic tumor debulking for management of locoregional endometrial cancer recurrence. DESIGN: Case report. SETTING: Tertiary referral center in New Haven, CT. INTERVENTIONS: A 70-year-old patient with a history of stage IB endometrioid endometrial cancer presented with rectal bleeding 3 years after the completion of treatment. A mass involving the distal sigmoid colon/upper rectum and bilateral distal periureteral masses were visualized on imaging. There was no distant metastatic disease. Colonoscopic biopsies were consistent with endometrial cancer recurrence. Because the patient was symptomatic with rectal bleeding and had no distant metastasis, it was recommended that she undergo surgical resection for management of this locoregional recurrence. The patient was placed in reverse Trendelenburg position with a rightward tilt to mobilize the splenic flexure. Once the cephalad aspect of the descending colon mobilization was completed, the patient was placed in Trendelenburg lithotomy position to expose the pelvis. A robot was docked at this point and the pelvic avascular spaces were delineated. A medial-to-lateral approach was used in mobilization of the sigmoid colon mesentery. The left ureter was identified and the sigmoid branches of inferior mesenteric artery were sealed. The descending/sigmoid colon junction was stapled. After complete mobilization of the sigmoid colon, the tumor-free upper rectum was delineated and stapled. Attention was then turned to the distal peri-ureteral masses. The 2-cm mass on the right, which was densely adherent to the distal right ureter, was completely resected after extensive ureterolysis. The resection of the 4-cm mass on the left which involved both the distal left ureter and the bladder dome required an intentional cystotomy and a partial cystectomy to attain negative margins (Supplemental Figure 1). The procedure was continued with the bowel anastomosis. The anvil was introduced through the vagina and was placed into the proximal limb through an antimesenteric incision. An end-to-end tension-free anastomosis was performed and adequate vascularization was confirmed with intravenous indocyanine green. CONCLUSION: Robotic low anterior resection and partial bladder resection were performed without any complications with negative margins. Robotic tumor debulking should be considered in appropriate patients when managing locoregional recurrence of endometrial cancer [1,2].

RESUMEN

Bladder Paraganglioma is a rare type of bladder tumor (0.06%). It is typically benign and the most common symptoms are hematuria, hypertension and headache. About 14% of these tumors are malign and consequently radio and chemoresistants. Therefore, surgery is the mainstay of treatment. As they are likely to recur and to metastize lifelong follow-up is required. The authors report a rare case of a 53 years old man with hematuria and a previous history of micturition syncope who was diagnosed with bladder lesion. During the transurethral ressection of bladder he became severely hypertensive. Plasma metanephrines, and urinary vanillylmandelic acid, were still high and the exams suggested residual tumor. The patient underwent radical cistoprostatectomy. After 4 years of follow-up the patient remains disease free.

RESUMEN

INTRODUCTION: The diagnosis of bladder urothelial tumors is based on bladder resection and histological analysis of the specimen. The time to obtain the results of the histological analysis increases the treatment delay. Furthermore, the lack of muscle on the specimen forces the surgeon to practice on other procedure. Full field optical coherence tomography (FFOCT) is a recent imaging technique to analyze tissue. The aim of our study was to evaluate the feasibility and diagnostic accuracy of FFOCT to detect muscle and tumor in bladder resection specimen. PATIENTS AND METHODS: We analyzed with the FFOCT technique bladder resection specimen of 24 consecutives patients. Three readers did the blind analyze of the images, looking for the presence of muscle and tumor on each specimen. Their results were compared with histological analysis to calculate diagnostic accuracy for each reader. RESULTS: Mean sensibilities for the detection of muscle and tumor were respectively 75% and 81%. Mean specificities for the detection of muscle and tumor were respectively 78.3% and 55.3%. CONCLUSIONS: Our results suggest that the FFOCT is feasible to analyze bladder resection specimen. Sensibilities and specificities calculated are encouraging for the detection of muscle and tumor. The accuracy of this detection and early-staging tool should be validated by larger studies. LEVEL OF EVIDENCE: 3.

RESUMEN

Background: Pheochromocytomas typically are diagnosed in the adrenal gland and from the sympathetic nervous system. Bladder pheochromocytoma is a rare location for this tumor. Case Presentation: We describe a 67-year-old Afro Caribbean woman referred to our hospital for an asymptomatic bladder tumor. Preliminary transurethral resection revealed bladder pheochromocytoma. After a comprehensive endocrine evaluation, we performed a robot-assisted laparoscopic partial cystectomy with ureteral reimplantation. Conclusion: We present a rare case of bladder pheochromocytoma treated effectively with minimally invasive techniques. When confronted with a solid bladder mass, apart from the more common urothelial malignancies, a differential diagnosis of bladder pheochromocytoma should also be considered.

RESUMEN

OBJECTIVE: To evaluate fertility outcomes after laparoscopic partial bladder resection in women with bladder endometriosis and to review the literature. STUDY DESIGN: A retrospective study conducted at two tertiary referral centres -Tenon University Hospital and Poissy University Hospital (Canadian Task Force Classification Level II-2)-from July 2006 to November 2015. Patients with bladder endometriosis who underwent either laparoscopic partial bladder resection (PBR) alone for those without posterior endometriotic lesions (PBR group) or both laparoscopic PBR and associated posterior deep infiltrating endometriosis (DIE) resection (PBR-PDIE group) were included. Pregnancy and live birth rates according to prior infertility, and associated posterior DIE resection were analysed. RESULTS: Thirty-four patients were included; 15 in the PBR group and 19 in the PBR-PDIE group. The median age (range) was 31 years (25-37), Seventeen patients (50%) had prior infertility. The median follow-up after bladder resection was 60.6 months (12-116). Overall, of the 25 (73.5%) patients who wished to conceive, 17 (68%) achieved pregnancies resulting in a live birth rate of 76.4%. Among the 17 patients with prior infertility, nine (52.9%) conceived. Overall, eight patients (53.3%) in the PBR group conceived and nine (47.3%) in the PBR-PDIE group (difference not significant). CONCLUSION: The present study demonstrates that laparoscopic PBR results in a high pregnancy rate in patients with prior infertility as well as in those with associated posterior DIE suggesting that surgery could be an acceptable alternative to first-line assisted reproductive technology.

RESUMEN

A 71-year-old woman who had been treated with methotrexate (MTX) and prednisolone for rheumatoid arthritis since 2010 presented with hematuria. Cystitis was diagnosed. Chest and abdominal CT images revealed a bladder tumor, with lung and bilateral adrenal metastases. Transurethral resection of the bladder tumor (TUR-BT) confirmed these findings in September 2014. Histological findings of the bladder included large atypical lymphoid cells indicating diffuse large B-cell lymphoma. After TUR-BT, CT imaging showed that the tumor had shrunk. Still, MTX was continued. She was diagnosed with MTX-related lymphoproliferative disorders in November 2014 and MTX was discontinued. Fluorodeoxyglucose-positron emission tomography on March 2015 showed a complete response.

RESUMEN

CONTEXT: Endourologic procedures are very common in daily urologic practice for treatment of benign prostatic obstruction, stone disease, urothelial tumors, or stenosis. OBJECTIVE: To characterize the complications following endoscopic procedures, to describe their management, and to gather information about their prevention in current urologic practice. EVIDENCE ACQUISITION: A review of the literature was conducted using PubMed/Medline database to include the most relevant articles on the topic. The search focused on endoscopic approaches for treatment of prostate, bladder, or upper urinary tract disease. Percutaneous approaches and noninvasive extracorporeal techniques were excluded. Complications of endourologic procedures were identified through level 1 evidence, systematic reviews of the literature, or original articles assessing complications as the primary end point. Data about management and prevention of each type of complication were retrieved in a second round using specific keywords. EVIDENCE SYNTHESIS: Complications of endoscopic urologic procedures are specific to each surgical approach. Main complications after prostate surgery include transurethral resection of the prostate syndrome, bleeding and transfusion, acute urinary retention, urinary tract infection, clot retention, postoperative irritative symptoms, ejaculatory dysfunction, urinary incontinence, bladder neck contracture, and urethral stricture. Major complications after transurethral bladder tumor include severe bleeding, transfusion, bladder perforation, and urinary tract infection. The most frequent complications after ureteroscopy are fever and sepsis, bleeding, steinstrasse, and ureteral injury. Overall, the literature is very poor, with no systematic reporting of complications and underuse of classification systems. No clear protocols are available for management of complications, and most are based on studies with low levels of evidence. Good clinical practice recommendations and guidelines give useful support about technical issues, intraoperative safety, and prevention of urinary tract infection. The efficacy of these preventive measures remains poorly investigated. CONCLUSIONS: Complications following endoscopic surgery are potentially numerous and vary with patient characteristics, surgical approach, and type of medical device. Improved standardization and quality of publications are warranted to improve knowledge of these issues, which are directly linked to the level of care. PATIENT SUMMARY: We focused on the potential complications of each endoscopic approach used to treat urologic disease. We described the frequency of these complications and gathered information about how to manage them in the operating theater. We also noted caveats for the literature regarding standardization of reporting and classification systems.
