RESUMO

OBJECTIVE: The study evaluated the anatomical and functional outcomes, as well as the safety data of laparoscopic sacrocolpopexy (LSC) for pelvic organ prolapse (POP) using a lightweight macroporous mesh. METHODS: A multicentric observational study was developed including five expert centers between March 2011 and December 2019. Inclusion criteria were female patients with symptomatic ≥stage II POP (POP-Q classification), who underwent a LSC. A lightweight and macroporous mesh device (Surelift Uplift) was used. Baseline anatomical positions were evaluated using POP-Q stage. The anatomical outcomes and procedural complications were assessed during the postoperative period. Primary outcomes were anatomical success, defined as POP-Q stage ≤I, and subjective success, defined as no bothersome bulge symptoms, and no repeat surgery or pessary use for recurrent prolapse. RESULTS: A total of 325 LSCs were analyzed with a median patient age of 66 (interquartile range [IQR] 61-73). After a median follow-up of 68 months (IQR 46.5-89), anatomical success was found in 88.9%, whereas subjective success was seen in 98.5% of the patients. Recurrent prolapse presented as cystocele (1.5%). Reported complications were bladder (4.6%) or rectum lesions (0.6%), de novo urinary incontinence (12.9%), and mesh extrusion (1.2%). CONCLUSIONS: LSC provides significant clinical improvement and excellent anatomical results, with a low risk of serious complications for women with ≥2 grade POP in a real clinical practice setting.

RESUMO

Introduction: Transplantation surgery teams often have to face complex cases. In certain circumstances, such as occlusion of the iliac vessels or prior pelvic surgery, heterotopic kidney transplantation may not be feasible and orthotopic kidney transplantation (OKT) could be a good alternative. Kidney autotransplantation (KAT) has been described as a potential treatment for complex renovascular, ureteral, or neoplastic conditions. There are scarce data regarding the complications and outcomes of these procedures; therefore, we present our experience. Materials and Methods: We retrospectively analysed the medical records of both 21 patients who had received OKT and 19 patients who underwent KAT between 1993 and 2020. We collected demographic features and data regarding surgical technique, complications, and graft outcomes. Kidney graft survival was calculated using Kaplan-Meier survival analysis. Results: Regarding OKT, in 15 (71.43%) cases, it was the first kidney transplantation. The most common indication was the unsuitable iliac region due to vascular abnormalities (57.14%). The early postoperative complication rate was high (66.67%), with 23.81% of Clavien grade 3b complications. During the follow-up period (mean 5.76 -SD 6.15- years), we detected 9 (42.85%) graft losses. At 1 year, the survival rate was 84.9%. Concerning KAT, the most frequent indication was ureteral pathology (52.63%), followed by vascular lesions (42.11%). The overall early complication rate was 42.11%. During the follow-up period (mean of 4.47 years), 4 (15.79%) graft losses were reported. Conclusions: Although OKT and KAT have high complication rates, these techniques can be considered as two valuable approaches for complex cases, in the absence of other therapeutic options.

RESUMO

PURPOSE: Prostatic multi-parametric magnetic resonance imaging (mpMRI) has markedly improved the assessment of men with suspected prostate cancer (PCa). Nevertheless, as mpMRI exhibits a high negative predictive value, a negative MRI may represent a diagnostic dilemma. The aim of this study was to evaluate the incidence of positive transperineal saturation biopsy in men who have negative mpMRI and to analyse the factors associated with positive biopsy in this scenario. PATIENTS AND METHODS: A retrospective study of men with normal mpMRI and suspicion of PCa who underwent saturation biopsy (≥20 cores) was carried out. A total of 580 patients underwent transperineal MRI/transrectal ultrasound fusion targeted biopsies or saturation prostate biopsies from January 2017 to September 2020. Of them, 73 had a pre-biopsy negative mpMRI (with Prostate Imaging - Reporting and Data System, PI-RADS, ≤2) and were included in this study. Demographics, clinical characteristics, data regarding biopsy results and potential predictive factors of positive saturation biopsy were collected. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for MRI-invisible PCa. RESULTS: The detection rate of PCa with saturation biopsy in patients with negative MRI was 34/73 (46.58%). Out of 34 MRI-invisible prostate cancers detected, 12 (35.29%) were clinically significant PCa (csPCa) forms. Regarding factors of positive biopsy, in univariate analysis, the use of 5-alpha reductase inhibitors and free:total prostate-specific antigen (PSA) ratio were associated with the result of the saturation biopsy. In multivariate analysis, only an unfavourable free:total PSA ratio remained a risk factor (OR 11.03, CI95% 1.93-63.15, p=0.01). Furthermore, multivariate logistic analysis demonstrated that prostate volume >50mL significantly predicts the absence of csPCa on saturation biopsy (OR 0.11, 95% CI 0.01-0.94, p=0.04). CONCLUSION: A free:total PSA ratio <20% is a risk factor for MRI-invisible PCa. Saturation biopsy could be considered in patients with suspected PCa, despite having a negative MRI.

RESUMO

BACKGROUND: Hypothermic machine perfusion (HMP) of deceased donor kidneys is associated with a better outcome than static cold storage, predominantly in marginal donors. Nevertheless, there is little evidence supporting whether graft centre of origin and donor category impact HMP results. OBJECTIVE: To identify factors impacting HMP in transplantation from marginal donors. DESIGN, SETTING, AND PARTICIPANTS: Analysis of prospectively collected cohort data of expanded criteria donor (ECD) and donor after circulatory death (DCD) categories II and III was performed. A total of 214 adult recipients of first kidney transplantation with complete data and a minimum of 6-mo follow-up were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Delayed graft function (DGF) was defined as the lack of decrease in creatinine level in the first 48h. Graft loss was defined as return to dialysis or creatinine clearance <15ml/min/1.73m2. Univariate and multivariate logistic regression analyses for DGF were constructed to identify independent risk factors. Recipient and graft survival (GS) analyses were conducted by Kaplan-Meier, and univariate and multivariate Cox regression analyses. RESULTS AND LIMITATION: DGF occurred in 32.8% of imported and 20.5% of local grafts (p=0.059). Only donor category (DCD; odds ratio [OR]: 6.6, p=0.008) and haemodialysis (OR: 3.5, p=0.002) were significantly associated with DGF development. The 1-yr GS rate was 92.5% in the local donor group and 84.3% in the imported donor group (p=0.050). Multivariate analysis by Cox proportional hazards model identified only donor category (hazard ratio [HR] 10.99, p=0.001) and donor age (HR 1.07, p=0.005) as predictive variables for GS. The small sample size of the DCD group diminished the statistical power and did not permit a subgroup analysis to determine the impact of specific DCD category on HMP results. CONCLUSIONS: DCD donor category, but not donor centre of origin, impacted DGF development and GS in the HMP of deceased donor kidneys. PATIENT SUMMARY: Currently, the number of donors is insufficient to meet the demand for renal grafts. Expanded criteria for donation after brain death and donation after circulatory death (DCD) programmes have been developed as strategies to minimise this problem. Hypothermic machine perfusion has previously demonstrated its usefulness in expanded criteria donation and DCD preservation. DCD type and donor age increase the risk of graft loss.

RESUMO

OBJETIVO: Las complicaciones urológicos mayores, fístulas y estenosis, afectan principalmente a la anastomosis vesico-ureteral y se presentan en el periodo temprano post-trasplante (TR). El empleo sistemático de catéteres ureterales continúa siendo controvertido con muchos grupos utilizándolos sólo de forma selectiva en función de la existencia de factores de riesgo pretrasplante o intraoperatorios. MÉTODOS: Se llevó a cabo una revisión de la literatura mediante la búsqueda automatizada en las bases de datos bibliográficas Medline como fuente bibliográfica principal y en Clinical Key. La estrategia de búsqueda incluyó los siguientes términos: 'stent' AND 'kidney transplantation'. RESULTADOS: La revisión de la literatura puso de manifiesto el efecto protector del empleo de catéteres ureterales en la ureteroneocistostomía del TR tanto para el desarrollo de fístulas (RR 0,29, 0,12 a 0,74, p=0,009) como de estenosis (RR 0,27, 0,09 a 0,81, p=0,02). El empleo de catéteres en pacientes inmunodeprimidos se asoció a un incremento significativo en la incidencia de ITUs post-TR (RR 1,49 IC 95% 1,04 a 2,15, p=0,03) que fue prevenida por la profilaxis antibiótica dirigida a la neumonía por pneumocistis carinii con cotrimoxazol. Las tasas de permeabilidad de los stent metálicos autoexpandibles y los by-pass extra-anatómicos en el tratamiento de la estenosis ureteral post-TR en pacientes de alto riesgo quirúrgico o tras el fracaso previo de la cirugía, con un número limitado de pacientes incluidos, ha variado entre el 50% y el 100%. CONCLUSIONES: El empleo de un catéter ureteral en la ureteroneocistostomía extravesical disminuye la incidencia de complicaciones anastomóticas. El tratamiento de elección de la estenosis ureteral post-TR es el tratamiento quirúrgico. El uso de stents metálicos y by-pass extraanatómicos debe limitarse al tratamiento de estenosis ureterales complejas en las que ha fallado el tratamiento primario, pacientes con elevado riesgo quirúrgico o disfunción crónica del injerto


OBJECTIVE: Mayor urological complications, fistulae and stenosis, mainly affect the vesicoureteral anastomosis and present in the early post-transplant period. The systematic use of ureteral catheters keeps selecbeing controversial with many groups using them only selectively depending on the existence of pretransplant or intraoperative risk factors. METHODS: We performed a bibliographic review through automatized search in the Medline bibliographic database, as the main bibliographic source, and also in Clinical Key. The search strategy included the following terms: 'stent' AND 'kidney transplantation'. RESULTS: The bibliographic search revealed the protective effect of the use of ureteral catheters in the transplant ureteroneocystostomy for both development of fistulae (RR 0.29, 0.12 to 0.74, p = 0.009) and stenosis (RR 0.27, 0.09 to 0.81, p = 0.02). The use of catheters in immunosuppressed patients was associated with significant increase of the incidence of post-transplant urinary tract infections (RR 1.49 IC 95% 1.04 to 2.15, p = 0.03) that was prevented by antibiotic prophylaxis with cotrimoxazole directed against pneumocistis carinii. The rates of permeability of self-expandable metallic stents and extra-anatomic bypasses in the treatment of ureteral stenosis after renal transplantation in high surgical risk patients or after the failure of previous surgery, has varied from 50% to 100%, with a limited number of patients included. CONCLUSIONS: The use of ureteral catheters in the extravesical ureteroneocystostomy reduces the incidence of anastomotic complications. Surgery is the treatment of choice of post-transplant ureteral stenosis. The use of metallic stents and extra-anatomic bypasses should be limited to complex ureteral stenosis when primary therapy has failed, in high surgical risk patients or chronic graft dysfunction
