ABSTRACT
Kidney transplant is the best treatment option for patients with end-stage renal disease. It reduces mortality and improves the quality of life. However, kidney transplant presents medical and surgical complications, and one of the most common is the posttransplant lymphocele. Lymphocele complication has an incidence of up to 20% and presents with variable clinical symptoms, which are directly associated with the size and compression effect on the adjacent organs. There are reported risk factors that favor the appearance of lymphocele. Despite known factors, there are more relevant factors (male sex, deceased donor, and corticosteroids) to carry out a stricter follow-up. The treatment of lymphoceles can vary according to the severity of the symptoms, characteristics of the collection, and the patient's clinical status. Despite the high recurrence, percutaneous intervention is the initial approach in this condition. If percutaneous aspiration, drainage, and sclerotherapy are unsuccessful, then open or laparoscopic fenestration can be performed; laparoscopy is the standard of treatment since it is highly effective and has few adverse effects.

OBJECTIVE: To determine the factors for failure of endoscopic ureteric stenting in patients with malignant ureteric obstruction. METHODS: We performed a search strategy in the Medical Literature Analysis and Retrieval System Online (MEDLINE), the Excerpta Medica dataBASE (EMBASE), the Literatura Latino-Americana e do Caribe em Ciências da Saúde database (LILACS), and the Cochrane Central Register of Controlled Trials (CENTRAL) databases. We included patients with malignant ureteric obstruction, who had a JJ catheter insertion. The studies reported the percentage of failure and risk factors, e.g. bladder invasion or deformity of the trigone, hydronephrosis, renal failure, previous radiotherapy, age, obstruction aetiology, and patient's health status. We performed a meta-analysis using R software ('meta' and 'metafor' libraries). RESULTS: We included nine studies that met the inclusion criteria, with 761 patients and an average age of 60.5 years. The studies assessed the time to failure during the first 30 days. The reported failure rate was 32% (95% confidence interval [CI] 21-45%; I2 = 88%). Regarding risk factors for failure, bladder invasion or deformity of the trigone had a hazard ratio (HR) of 4.8 (95% CI 1.28-8.5; I2 = 97.4%); severe hydronephrosis had a HR of 3.92 (95% CI 0.32-7.52; I2 = 93.9%); and age <65 years had a HR of 0.93 (95% CI 0.8-0.9; I2 = 0%). CONCLUSIONS: We found a high probability of failure for endoscopic urinary decompression in patients with malignant ureteric obstruction. Factors such as bladder invasion or deformity of the trigone and age >65 years had an increased risk of failure.

BACKGROUND: The purpose of this study was to determine the effectiveness of an adjustable sling compared with an artificial urinary sphincter (AUS) in patients with severe urinary incontinence (SUI) postprostatectomy (PP). METHODS: This review was carried out following the Cochrane Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) declaration. We searched Medline, Embase, LILACS, and CENTRAL databases. Studies with patients older than 18 years of age with SUI PP who underwent sling or AUS intervention and had been monitored for longer than 12 months were included. RESULTS: Seven studies were included, yielding a sample size of 420. Pads were reportedly dry or improved in 70% of the sling group compared with 74% in the AUS group. The Incontinence Impact Questionnaire, Short Form (IIQ-7) was the most frequently used scale and showed improvement, with a score of 82.8% in the AUS group compared with 86.1% in the sling group. When comparing interventions with nonintervention, relative risks (RRs) of 35.37 (95% confidence interval [CI]: 7.17-174.35) and 45.14 (95% CI: 11.09-183.70) were found for the adjustable sling and AUS, respectively, which were statistically significant. No significant differences were found when AUS versus adjustable sling were compared, with an RR of 0.78 (95% CI: 0.09-6.56). We found a low risk of bias in most studies. CONCLUSIONS: Both interventions can reduce incontinence and improve the quality of life of patients with SUI PP. The published literature is substantially limited as no randomized clinical trials are available, no consensus has been reached regarding the definition of severity of incontinence, and considerable heterogeneity exists across the outcome variables measured.
