RESUMO
PURPOSE: Open ureteral reimplantation is considered the standard surgical approach to treat distal ureteral strictures or injuries. These procedures are increasingly performed in a minimally invasive and robotic-assisted manner. Notably, no series comparing perioperative outcomes and safety of the open vs. robotic approach are available so far. METHODS: In this retrospective multi-center study, we compared data from 51 robotic ureteral reimplantations (RUR) with 79 open ureteral reimplantations (OUR). Both cohorts were comparatively assessed using different baseline characteristics and perioperative outcomes. Moreover, a multivariate logistic regression for independent predictors was performed. RESULTS: Surgery time, length of hospital stay and dwell time of bladder catheter were shorter in the robotic cohort, whereas estimated blood loss, postoperative blood transfusion rate and postoperative complications were lower than in the open cohort. In the multivariate linear regression analysis, robotic approach was an independent predictor for a shorter operation time (coefficient - 0.254, 95% confidence interval [CI] - 0.342 to - 0.166; p < 0.001), a lower estimated blood loss (coefficient - 0.390, 95% CI - 0.549 to - 0.231, p < 0.001) and a shorter length of hospital stay (coefficient - 0.455, 95% CI - 0.552 to - 0.358, p < 0.001). Moreover, robotic surgery was an independent predictor for a shorter dwell time of bladder catheter (coefficient - 0.210, 95% CI - 0.278 to - 0.142, p < 0.001). CONCLUSION: RUR represents a safe alternative to OUR, with a shorter operative time, decreased blood loss and length of hospital stay. Prospective research are needed to further define the extent of the advantages of the robotic approach over open surgery.

OBJECTIVE: To assess the clinical efficacy of laparoscopic Lich-Gregoir (LLG) and transvesicoscopic Cohen reimplantation (TCR) in the treatment of vesicoureteral junction obstruction (VUJO) and vesicoureteral reflux (VUR). METHODS: This study retrospectively analyzed the clinical data of 66 pediatric patients with VUJO and VUR. They were classified into two groups, undergoing either the laparoscopic Lich-Gregoir operation (LLGO) (n = 35) or transvesicoscopic Cohen reimplantation operation (TCRO) (n = 31). The surgeries were performed between April 2018 and September 2022 at the First Affiliated Hospital of Guangxi Medical University, China. General characteristics, preoperative attributes, postoperative complications, renal function recovery, and improvement of hydronephrosis were compared between the two groups. RESULTS: All surgical procedures were successful with no requirement for reoperation. Both groups were comparable with respect to gender, affected side, weight, and postoperative complications. Nonetheless, the LLGO group contained a greater number of children younger than 12 months. The LLGO group demonstrated superiority over the TCRO group regarding the duration of the operation, intraoperative blood loss, and length of postoperative hospital stay. In contrast, postoperative complications, recovery of renal function, and hydronephrosis improvement did not exhibit statistically significant differences between the two groups. CONCLUSION: Both LLGO and TCRO were demonstrated to be precise, safe, and reliable surgical methods for treating pediatric VUJO and VUR. LLGO ureteral reimplantation offers particular advantages in selecting cases and appears more suitable for children younger than 12 months who have a small bladder capacity.

OBJECTIVE: To observe the safety and short-term outcomes of a new way of laparoscopic trocar placement in pediatric robotic-assisted Lich-Gregoir ureteral reimplantation for vesicoureteral reflux. METHODS: The retrospective study included 32 patients under 14 years diagnosed with primary vesicoureteral reflux (VUR). All these patients underwent robotic-assisted Lich-Gregoir ureteral reimplantation in our department from December 2020 to August 2022. These patients were divided into the following groups according to the different ways of trocar placement: 13 patients in group single-port plus one (SR) and 19 patients in group multiple-port (MR). Patients' characteristics as well as their perioperative and follow-up data were collected and evaluated. RESULTS: There was no significant difference in the data regarding patients' characteristics and preoperative data. These data included the grade of vesicoureteral reflux according to the voiding cystourethrogram (VCUG), and the differential degree of renal function (DRF) at the following time points: preoperative, postoperative, and comparison of preoperative and postoperative. There was no difference between the two groups. During surgery, the time of artificial pneumoperitoneum establishment, ureteral reimplantation time, and total operative time in the SR group were longer than those in the MR group. Yet only the time of artificial pneumoperitoneum establishment shows a statistical difference (P < 0.0001). Also, the peri-operative data, including the volume of blood loss, fasting time, hospitalization, and length of time that a ureteral catheter remained in place, and the number of postoperative complications demonstrate no difference. In addition, the SFU grade and VCUG grade at the following time point also show no difference between the two groups. CONCLUSION: The study demonstrates that SR in robotic-assisted Lich-Gregoir ureteral reimplantation has reached the same surgical effects as MR. In addition, the single-port plus one trocar placement receives a higher cosmetic satisfaction score from parents and did not increase the surgical time and complexity.

BACKGROUND: The optimal timing for reimplantation for periprosthetic joint infection (PJI) has not been established and varies from a few weeks to several months. The aim of this study was to assess the commendable time between implant removal and reimplantation in patients who underwent two-stage exchange arthroplasty for PJI. METHODS: We retrospectively reviewed 361 patients who were treated with two-stage exchange arthroplasty for hip and knee chronic PJI at our institution between January 2000 and December 2018. Patient characteristics, comorbidities, surgical variables, microbiology data, and time to reimplantation were recorded. All patients were followed for a minimum of one year. Treatment failure was defined by Delphi criteria. Logistic regression analyses were used to calculate survival rates and adjusted odds ratios (ORs) of treatment failure. RESULTS: In final analysis, 27 (7.5%) had treatment failure. Factors related to treatment failure including interim spacer exchange (OR, 3.13; confidence interval (CI), 1.04-9.09, p = 0.036), higher ESR level at reimplantation (OR, 1.85; CI, 1.05-3.57; p = 0.04), and time to reimplantation (OR, 1.00; CI, 1.003-1.005, p = 0.04). Performing revision arthroplasty surgery from 16 to 20 weeks had highest successful rate. The reimplantation over 24 weeks had a lower successful rate. However, no statistical significance in comparing each interval group. CONCLUSION: Our study emphasized the importance of timely reimplantation in achieving successful outcomes. Factors such as ESR levels, spacer exchange, and the duration of time to reimplantation influenced the likelihood of treatment failure in two-stage exchange arthroplasty for hip and knee PJI.

OBJECTIVES: Recently, patients with certain legacy cochlear implants (CIs) have sought out reimplantation to enjoy the benefits offered by newer processor technology. This decision can be difficult, especially when the individual relies exclusively on the device for communication and scores at the ceiling of performance metrics. To date, most outcome data is derived from reimplantation of a non-functioning CI-a relatively easy decision. The aim of this study is to report hearing outcomes following reimplantation of legacy implants to guide surgeons and patients approaching this high-stakes clinical situation. PATIENTS AND INTERVENTION: Four patients implanted with Advanced Bionics Clarion C1 devices over 20 years ago underwent reimplantation. RESULTS: Three reimplanted patients demonstrated a maintenance or improvement in their audiometric performance with one patient experiencing only a 5 % decrease in AzBioQ score. Each patient expressed satisfaction with the expansion of technological capabilities including improved battery life, and device connectivity. There were no failed reimplantations or other adverse effects. CONCLUSIONS: Reimplantation of a functioning legacy CI result in stability or improvement in auditory performance. All individuals in this series report that they enjoy the new connectivity and programming technologies. As the rate advancement in CI technology continues to increase and newer device architectures emerge, these data will help to inform the decision to reimplant functioning devices.

OBJECTIVES: The aim of this study was to present an institution's experience with cochlear reimplantation (CRI), to assess surgical challenges and post-operative outcomes and to increase the success rate of CRI. STUDY DESIGN: Retrospective single-institution study. SETTING: Tertiary medical center. METHODS: We retrospectively evaluated data from 76 reimplantation cases treated in a tertiary center between 2001 and 2022. Clinical features including etiology of hearing loss, type of failure, surgical issues, and auditory speech performance were analyzed. Categorical Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores were used to evaluate pre- and post-CRI outcomes. RESULTS: The CRI population comprises of 7 patients from our institute,69 referred patients from other centers. Device failure was the most common reason (68/76, 89.5 %) for CRI; in addition, there were 7 medical failures and 1 had both soft device failure. Medical failures included flap rupture and device extrusion, magnet migration, auditory neuropathy, leukoencephalopathy, foreign-body residue and meningitis. In 21/76 patients, the electrode technology was upgraded. The mean time to failure was 0.58-13 years, with a mean of 4.97 years. The mean (± SD) CAP and SIR scores before and after CRI were 5.2 ± 1.2 versus 5.5 ± 1.1 and 3.4 ± 1.1 versus 3.5 ± 1.1, respectively. Performance was poor in six patients with severe cochlear malformation, auditory nerve dysplasia, leukoencephalopathy, and epilepsy. CONCLUSION: CRI surgery is a challenging but relatively safe procedure, and most reimplanted patients experience favorable postoperative outcomes. Medical complications and intracochlear damage are the main causes of poor postoperative results. Therefore, adequate preoperative preparation and atraumatic CRI should be carried out for optimal results.

INTRODUCTION: The incidence of cochlear implantation failure is rare; however, complications can arise in which revision surgery becomes necessary. The purpose of this study is to review our institutional experience with revision cochlear implantation to further understand the surgical and audiological outcomes after cochlear implant failure. METHODS: This is a retrospective review of patients who underwent revision cochlear implantation from 2014 to 2022 at a single institution. RESULTS: Twenty-one patients required reimplantation within the 8-year study period. During this time frame, a total of 202 cochlear implants were implanted in 171 pediatric patients, resulting in a reimplantation rate of 5.9 %. Our reimplantation patient population were majority white (61.9 %), female (52.4 %), and insured by Medicaid (61.9 %). The average age at implantation was 54.8 months ±47.5 months and the average age at reimplantation was 100.1 months ±55.9 months. The average time between initial implantation and reimplantation was 46.2 months ±30.2 months. The most common sign of failure was abnormal impedances (47.6 %). Reimplantation was required more often for hard failure (76.2 %), which occurred secondary to trauma in 56.3 % of patients, and occurred more frequently in those ages 5-7. Operative findings were unremarkable in 81 % of patients. Those with audiologic data were noted to have stable or improved thresholds after their revision surgery. Three of the 21 patients discontinued use of their processor on the revised ear. Of these, two had known trauma associated with implant failure that was not immediately addressed. CONCLUSION: We noted increased rates of hard failure, most commonly secondary to trauma. We noted that majority of those who discontinued use of their implant after revision surgery had associated traumatic injuries that ultimately delayed their presentation and surgery.

PURPOSE: To assess the prevalence and management of acquired cholesteatoma after cochlear implantation in pediatric and adult patients. METHODS: Retrospective case review of pediatric and adult cochlear implants (CI) followed at a tertiary referral center and literature review of acquired cholesteatoma after CI surgery, to identify its prevalence, cause, and treatment. RESULTS: Nine pediatric CIs were diagnosed with cholesteatoma in seven patients after 6.4 ± 4 years from CI surgery, and two adults after 11.3 and 21.7 years from CI surgery. Thirty-four pediatric cases and 26 adult cases are described in the literature. Cholesteatoma has a prevalence of 0.54% in pediatric CIs, and 1.79% in adult CIs (case series and literature). Adult cases were diagnosed significantly later compared to pediatric cases (Mann-Whitney test, p = 0.0460). Three pediatric cholesteatomas were treated with conservative surgery and preservation of the CI; they all developed recurrent disease. The remaining pediatric cases underwent subtotal petrosectomy with simultaneous CI explantation and staged reimplantation. Only one case recurred. The adult cases underwent simultaneous subtotal petrosectomy, explantation, and reimplantation. Similarly, 33.3% of cases treated with conservative/reconstructive surgery in the literature required revision surgery or conversion to subtotal petrosectomy against 6.2% of subtotal petrosectomies in the literature. CONCLUSIONS: Cholesteatoma after CI is a rare and late-onset complication of CIs. It is more prevalent in the adult CI population, although it affects children significantly earlier. The treatment of choice is subtotal petrosectomy and CI explantation with simultaneous or staged reimplantation.

INTRODUCTION: Due to the increasing number of cochlear implant (CI) recipients, growing indications, and the aging population, the reimplantation of CI recipients has become a focus of attention. The aim of this study is to examine the causes, timing, and postoperative speech understanding in a large cohort over the past 30 years. METHODS: A retrospective data analysis was conducted on over 4000 CI recipients and 214 reimplanted children and adults from 1993 to 2020. This involved collecting and comparing data on causes, manufacturer information, and demographic data. In addition, a comparison of speech understanding in Freiburg monosyllables and numbers before and after reimplantation was carried out. RESULTS: Children did not exhibit elevated rates of reimplantation. The overall reimplantation rate in the entire cohort was 5%. The CI overall survival rate after 10 years in the entire cohort was 95.2%. Device failure was the most common reason for reimplantation, with 48% occurring within the first 5 years after implantation. The second most common reason was medical complications, with the risk of reimplantation decreasing as more time passed since the initial implantation. There were no significant differences in Freiburg numbers and monosyllable comprehension before and after reimplantation, both in the overall cohort and in the subcohorts based on indications. Even a technical upgrade did not result in a significant improvement in speech understanding. DISCUSSION: There was no significant difference in the frequency of reimplantation based on patient age, especially when comparing children and adults. Device failure is by far the most common indication for reimplantation, with no significant difference in implant survival between manufacturers. Patients most often choose the same manufacturer for reimplantation. The likelihood of reimplantation decreases with increasing time since the initial implantation. The indication for reimplantation should be carefully considered, as on average, no improved speech understanding is achieved, regardless of the cause, even with a technical upgrade.

BACKGROUND: Two-stage prosthesis exchange is the treatment of choice for chronic periprosthetic joint infection (PJI) of a total hip arthroplasty (THA), especially when the bone and surrounding soft tissues are compromised or difficult-to-treat pathogens are implicated. The aims of our study were as follows: (1) to determine the outcome of 2-stage prosthesis exchange for the treatment of PJI after THA and (2) to determine the risk factors for reinfection leading to subsequent revision surgeries after reimplantation. METHODS: We prospectively enrolled 187 consecutive patients who underwent a 2-stage THA exchange with resection arthroplasty for PJI from 2013 to 2019. The mean (± SD) duration of follow-up was 54.2 ± 24.9 months (range, 36 to 96), and the mean interval until reimplantation was 9.8 ± 8.9 weeks (range, 2 to 38). All patients remained in a spacer-free girdlestone situation between the 2 stages of treatment. Patients who remained infection-free after their 2-stage treatment were considered to have achieved treatment success. RESULTS: The overall success rate was 85.6%. The cumulative probability of reinfection was 11.5% after one year and 14% after 2 years after reimplantation. High virulence or difficult-to-treat pathogens were significant and independent risk factors for reinfection (HR [hazard ratio] = 3.71, 95% CI [confidence interval]: 1.47 to 9.36, P = .006 and HR = 3.85, 95% CI: 1.73 to 8.57, respectively, P = .001), as was previous 2-stage hip prosthesis exchange (HR = 3.58, 95% CI: 1.33 to 9.62, P = .01). Overall reoperation and revision rates were 26.2 and 16.6%, respectively. Re-infected patients had an 80% higher probability of reoperation than noninfected ones (P < .001, log-rank = 102.6), and they were 55% more likely to undergo revision surgery during their follow-up (P < .001, log-rank = 55.4). CONCLUSIONS: Reinfection rates after 2-stage spacer-free THA revision for PJI still remain high but are comparable to those including cement spacers. Patients who have had prior failed 2-stage implant exchanges or are infected by high-grade or difficult-to-treat pathogens are at high risk for treatment failure.
RESUMO
BACKGROUND: A 2-stage exchange revision for periprosthetic joint infection (PJI) is associated with major risks for reinfection. Although serum markers are frequently used for diagnosis, their effectiveness remains debatable. Synovial fluid markers may offer a more accurate diagnosis of PJI; however, the importance of these biomarkers, notably synovial fluid C-reactive protein (syCRP), remains controversial, particularly in the context of reimplantation. The present study aimed to clarify these diagnostic uncertainties by evaluating the diagnostic efficacy of syCRP versus serum CRP (seCRP) levels in the context of PJI and recurring or persisting infections before reimplantation. METHODS: A total of 186 patients were enrolled and divided into 2 groups: aseptic revision (n = 112) and PJI revision (n = 74). Of the PJI group, 65 were categorized as success and 9 as failure, based on the presence of recurrent or persistent infection before reimplantation. The syCRP and seCRP levels and their changes were assessed preoperatively and in the first-stage and second-stage revisions. Additionally, receiver operating characteristic (ROC) curves and area under the ROC curves (AUCs) were analyzed. RESULTS: Both seCRP and syCRP levels were significantly elevated in the PJI group compared with the aseptic group (P < .001). The ROC curve analysis highlighted the enhanced diagnostic accuracy of syCRP for PJI, with an AUC of 0.93 versus 0.80 for seCRP. Furthermore, syCRP proved to be more reliable in predicting reimplantation success, exhibiting an AUC of 0.86 versus 0.63 for seCRP. In evaluating trends in CRP levels to determine reimplantation timing, changes in syCRP levels demonstrated superior diagnostic utility, exhibiting an AUC of 0.79 versus 0.63 for changes in seCRP levels. CONCLUSIONS: In assessing PJI and infections before reimplantation, syCRP may offer enhanced accuracy compared with seCRP. Nevertheless, variations in both syCRP and seCRP levels did not consistently predict the outcome of reimplantation.

Macro-amputations are extremely serious traumas and represent one of the rare extreme emergencies in hand and upper limb surgery. Their rarity, especially in our developed countries, makes their treatment relatively unknown by surgical and anesthetic teams. However, the action plan to use during a macro-reimplantation, the decisive elements of pre- and post-operative management, and the key stages of the surgery, must be perfectly known, because they determine the success of a major reimplantation, for the limb survival and the future functional result. After a brief historical overview, the literature review proposed here provides an opportunity for an update on these formidable injuries and propose a treatment algorithm to guide the medical team in the management of these complex patients.
RESUMO
Objective: This study aimed to introduce and evaluate the feasibility and outcomes of a novel surgical technique, robot-assisted Foley tie ureteric tapering (RAFUT) and reimplantation, specifically designed for intravesical ureteral tapering during pediatric robotic-assisted ureteric reimplantation. Materials and Methods: A retrospective analysis was conducted on pediatric patients diagnosed with primary vesicoureteric reflux (VUR), who underwent RAFUT between January 2019 and July 2021. Patient records were reviewed to assess preoperative characteristics, operative details, and postoperative outcomes. RAFUT involved meticulous patient positioning, precise port placement with a 6 mm separation, and bladder anchoring to maintain pneumovesicum. Ureteric tapering was performed with the Foley tie technique to enhance surgical precision. The primary outcome measures included operative time, complications, and postoperative VUR resolution. Results: All four patients underwent successful intravesical RAFUT without any intraoperative or postoperative complications. The age of the patients ranged from 3 to 12 years, with varying bladder capacities (range: 210-550 mL). The operating times ranged from 180 to 210 min, and the estimated blood loss was 35-50 mL. None of the patients required conversion to open surgery. Patients demonstrated resolution of VUR on postoperative imaging, and none experienced recurrent urinary tract infections during follow-up, which ranged from 1.5 to nearly 4 years. Conclusion: RAFUT represents a safe and effective surgical technique for intravesical ureteral tapering during pediatric robotic-assisted ureteric reimplantation. This innovative approach addresses the challenges posed by intravesical surgery for dilated ureters, maintains anatomical orientation, and offers precise excision and suturing capabilities.
RESUMO
BACKGROUND: The cause of early septic failure after two-stage exchange revision total knee arthroplasty (TKA) for chronic periprosthetic joint infection (PJI) and the factors affecting it are not well known. The purpose of this study was to determine the surgical outcomes and the risk factors for early septic failure after two-stage revision TKA for chronic PJI. METHODS: We identified a total of 246 adult patients who met the Musculoskeletal Infection Society (MSIS) diagnostic criteria for chronic PJI at two academic tertiary hospitals from March 2012 to December 2018. Finally, 151 patients who consecutively received two-stage exchange revision TKA for chronic PJI and who had a minimum 3-year follow-up were enrolled and retrospectively reviewed. Successful surgical treatment was evaluated for two-stage revision TKA and risk factors for early septic failure were identified. RESULTS: Early septic failures occurred within 3 years after reimplantation in 48 patients (31.8%). After accounting for potentially confounding variables, we found that male patient [odds ratio (OR): 2.753, 95% confidence interval (CI) 1.099-6.893, p = 0.031], fungus or mycobacterial infection (OR: 5.224, 95% CI 1.481-18.433, p = 0.01), and positive culture at reimplantation (OR: 4.407, 95% CI 1.255-15.480, p = 0.021) were independently associated with early septic failure after two-stage exchange revision TKA. CONCLUSION: Male patients, fungus or mycobacterial infection, and positive culture at reimplantation were independently associated with an increased risk of early septic failure after two-stage exchange revision TKA despite normal C-reactive protein values prior to reimplantation. Further prospective and high-quality studies are needed to determine the risk factors of two-stage exchange revision TKA for chronic PJI. LEVEL OF EVIDENCE: level IV; retrospective comparison; treatment study.

Total joint arthroplasty is the recommended treatment for patients with end-stage osteoarthritis, as it reduces disability and pain and restores joint function. However, prosthetic joint infection is a serious complication of this procedure, with the two-stage exchange being the most common treatment method. While there is consensus on diagnosing prosthetic joint infection, there is a lack of agreement on the parameters that can guide the surgeon in performing definitive reimplantation in a two-stage procedure. One approach that has been suggested to improve the accuracy of microbiologic investigations before definitive reimplantation is to observe a holiday period from antibiotic therapy to improve the accuracy of cultures from periprosthetic tissues, but these cultures report some degree of aspecificity. Therefore, several pieces of evidence highlight that performing reimplantation using continuous antibiotic therapy should be considered a safe and effective approach, leading to higher cure rates and a shorter period of disability. Dosage of C-reactive protein (CRP), erythrocyte sedimentation rate (ERS) and D-dimer are helpful in diagnosing prosthetic joint infection, but only D-dimer has shown sufficient accuracy in predicting the risk of infection recurrence after a two-stage procedure. Synovial fluid analysis before reimplantation has been shown to be the most accurate in predicting recurrence, and new cutoff values for leukocyte count and neutrophil percentage have shown a useful predictive rule to identify patients at risk of unfavourable outcome. A new scoring system based on a numerical score calculated from the beta coefficient derived through multivariate analysis of D-dimer levels, synovial fluid leukocytes and relative neutrophils percentage has demonstrated high accuracy when it comes to guiding the second step of two-stage procedure. In conclusion, reimplantation may be a suitable option for patients who are on continuous therapy without local symptoms, and with CRP and ERS within the normal range, with low synovial fluid leukocytes (< 952/mL) and a low relative neutrophil percentage (< 52%) and D-dimer below 1100 µg/mL. A numerical score derived from analysing these three parameters can serve as a valuable tool in determining the feasibility of reimplantation in these patients.

PURPOSE OF THE REVIEW: Genital mutilation in males can range from minor injuries (cuts from a blade) to severe urological emergencies (testicular or penile amputation). Due to the rarity of these events, there is a lack of extensive reports, as most of the available literature is regarding single cases. Genital mutilation has been associated with psychotic and non-psychotic causes, psychiatric conditions, drug consumption, sexual practices, or even cultural or religious beliefs. It is crucial to perform a psychiatric evaluation of these patients to obtain the best therapeutic approach. This manuscript serves as a review of the currently available knowledge regarding male genital mutilation. RECENT FINDINGS: A great variety of reasons have been associated with genital mutilation. Previous authors have distinguished between those that present with a clear mental health precursor from cases with no psychotic background. Nevertheless, sometimes, it is difficult to make this distinction. Recently, reconstructive techniques for amputation cases have moved towards a microsurgical approach in order to improve outcomes. A holistic therapeutic approach must be performed to increase the chances of effective treatment. Close collaboration between urologists, psychiatrists, and emergency doctors is essential to ensure the best care for patients performing genital mutilation. Future publications must evaluate differences in treatment options and the impact that these have on the long-term well-being of patients undergoing genital self-mutilation.

BACKGROUND: Uretero-neocystostomy (UNC) is the gold-standard for distal-ureter repair. Whether the surgery should be conducted minimally invasive (laparoscopic (LAP), robotic RAL)) or open remains unanswered by the literature. METHODS: Retrospective analysis of surgical outcome of patients treated with UNC for distal ureteral stenosis (January 2012 - October 2021). Patient demographics, estimated blood loss (EBL), surgical technique, operative time, complications and length of hospital stay (LOS) were recorded. During the follow-up period, patient underwent renal ultrasound and kidney function tests. Success was defined as relieve of symptoms or no findings of obstruction needing urine drainage. RESULTS: 60 patients were included (9 RAL, 25 LAP, 26 open). The different cohorts were similar of age, gender, American Society of Anesthesiologists (ASA) score, body-mass index and history of prior treatment of the ureter. No intraoperative complications were detected in all groups. There was no conversion to open surgery in the RAL group, whereas one was found in the LAP arm. Six patients had a recurrent stricture, but with no significant difference between the cohorts. EBL was not different between the groups. LOS was significantly lower in the RAL + LAP group compared to open (7 vs. 13 days, p = 0.005) despite significantly longer operating times (186 vs. 125.5 min, p = 0.005). CONCLUSION: Minimal invasive UNC, especially RAL, is a feasible and safe surgical method and provides similar results in terms of success rates in comparison to open approach. A shorter LOS could be detected. Further prospective studies need to be done.

INTRODUCTION: The timing of surgical repair for ureterovaginal fistula (UVF) is under debate, here we introduce our experience to compare the safety and efficacy between early and delayed ureteral reimplantation for UVF. METHODS: Between January 2012 and January 2020, 22 patients who were diagnosed with UVF had received ureteral reimplantation. Baseline characteristics, history of previous abdominal surgery, operative profile, and follow-up data were collected and analyzed. RESULTS: Among 22 patients diagnosed with UVF, 12 patients received early ureteral reimplantation and others received delayed ureteral reimplantation. Both groups were comparable in baseline characteristics and detailed history of previous operations. The mean operative time of the early surgery group was 140.83 ± 35.28 min, while that of the delayed surgery group was 181.00 ± 43.83 min (p = 0.027). Patients of the early surgery group (183.33 ± 107.31 mL) had less blood loss compared with that of the delayed surgery group (285.00 ± 94.43 mL) (p = 0.030). After an overall mean follow-up of 34.55 months, the ureteral stricture rate of two groups was not statistically significantly different (16.67% in early repair vs. 40.00% in delayed repair, p = 0.348). CONCLUSION: With similar long-term outcomes, the early ureteral reimplantation had a shorter operative time and less blood loss. Moreover, the stress during the waiting period could be minimized. High-quality clinical studies with larger sample size are needed to confirm the superior nature of early surgery.

OBJECTIVE: Purpose This study aims to explore the clinical efficacy of laminospinous process ligament complex reimplantation combined with mini-titanium plate fixation in the treatment of thoracolumbar intraspinal tumors. METHODS: A retrospective analysis was performed on 43 cases of intraspinal tumors treated with thoracolumbar intraspinal tumor resection from August 2018 to March 2021, and 27 cases underwent laminospinous process ligament complex reimplantation combined with micro titanium plate shaping. Fixation (laminar replantation group), and 16 patients underwent laminectomy combined with pedicle screw internal fixation (laminectomy group). The operation time, blood loss, drainage tube removal time, cerebrospinal fluid leakage, spinal instability, and the incidence of secondary spinal stenosis were compared between the two groups. The pain VAS score, ODI score, and modified Macnab at the last follow-up were compared between the two groups. And the laminar fusion rate of the laminoplasty group was measured. RESULTS: Both groups successfully completed the surgery and obtained complete follow-up. The incidence of cerebrospinal fluid leakage and secondary spinal canal stenosis in the laminectomy group was lower than that in the laminectomy group, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the incidence of spinal instability between the two groups (P > 0.05). The operation time and intraoperative blood loss in the laminectomy group were less than those in the laminectomy group, and the drainage tube removal time was earlier than that in the laminectomy group. The difference was statistically significant (P < 0.05). At the final follow-up, there was no statistically significant difference in the pain VAS score, ODI score, and modified Macnab between the two groups (P > 0.05), but they were all significantly improved compared with preoperative ones. Fusion evaluation was conducted on the laminoplasty group. Two years after surgery, the fusion rate was 97.56% (40/41). CONCLUSIONS: The application of laminospinous process ligament complex reimplantation combined with mini titanium plate fixation during thoracolumbar intraspinal tumor resection can effectively reconstruct the spinal canal and posterior column structure, reduce the incidence of cerebrospinal fluid leakage and secondary spinal stenosis. The laminar fusion rate is high.

BACKGROUND: Giant middle cerebral artery (MCA) aneurysms are complex and challenging. Revascularization is frequently required in addition to trapping or clip reconstruction, and the MCA reimplantation bypass is ultimately needed when aneurysm excision is planned. METHOD: The operation was conducted in the hybrid operating suite, where an intraoperative cerebral angiography revealed a compromised MCA after multiple attempts of clip reconstruction. Therefore, we decided to perform an M2-M1 reimplantation bypass in conjunction with trapping and aneurysmectomy. CONCLUSION: Reimplantation bypass can be a rescue procedure for revascularization in complex aneurysms. The angioarchitecture varies among individuals; therefore, the optimal bypass technique should be tailored.
