- Antibiotics prophylaxis at the time of catheter removal after radical prostatectomy: a systematic review of the literature and meta-analysis(2024) SANTOS, Leticia Lourenco dos; FRAGA, Isabela de Almeida; ALMEIDA, Vitor Amaral de; SANTOS, Andressa Hellen Ribeiro; ALMEIDA, Isabelle Matos; NASCIMENTO, Tatiana Roberta; PORTO, Breno Cordeiro; PASSEROTTI, Carlo Camargo; ARTIFON, Everson Luiz de Almeida; OTOCH, Jose Pinhata; CRUZ, Jose Arnaldo Shiomi daPurpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections. Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords ""antibiotics"" AND ""prostatectomy"" AND ""urinary catheter."" Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.51; 95% confidence interval-95%CI 0.27-0.98; p = 0.04; I2 = 0%). No difference was found regarding the presence of bacteriuria (OR = 0.39; 95%CI 0.12-1.24; p = 0.11; I2 = 73%). Conclusions: In our meta-analysis, there was a significant decrease in urinary tract infection with antibiotic prophylaxis after indwelling urinary catheter removal following radical prostatectomy.
- PCNL vs. two staged RIRS for kidney stones greater than 20 mm: systematic review, meta-analysis, and trial sequential analysis(2024) CONSTANTINOU, Beatriz T.; BENEDICTO, Bianca C.; PORTO, Breno C.; BELKOVSKY, Mikhael; PASSEROTTI, Carlo C.; ARTIFON, Everson L.; OTOCH, Jose P.; CRUZ, Jose A. daINTRODUCTION: Percutaneous nephrolithotomy (PCNL) is considered the gold standard treatment for kidney stones greater than 20 mm. However, retrograde intrarenal surgery (RIRS) may achieve the same stone-free rate with repeated procedures, and potentially fewer complications. This study aimed to compare the efficacy and safety of PCNL and twostaged RIRS. EVIDENCE ACQUISITION: We conducted a systematic search in PubMed, Embase, Scopus, Cochrane, and Web of Science for studies comparing PCNL and RIRS for kidney stones greater than 20mm. The primary outcome is stone-free rate (SFR) of PCNL and RIRS (repeated once if needed). Secondary outcomes were SFR of PCNL versus RIRS (single procedure), operative time, hospital stay, need for auxiliary procedures, and complications. We performed a subgroup analysis for randomized trials, non-randomized trials, and patients with solitary kidney. We performed a trial sequential analysis for the main outcome. EVIDENCE SYNTHESIS: We included 31 articles, with 1987 patients in the PCNL and 1724 patients in RIRS. We confirmed the traditional result that after a single procedure PCNL has a higher SFR. We also found that comparing the SFR of PCNL and RIRS, repeated up to two times if needed, no difference in SFR was observed. Surprisingly, only 26% (CI95 23%-28%) of the patients required a second RIRS. In the trial sequential analysis, the last point of the z-curve was within futility borders. We observed that PCNL has a higher incidence of complications (RR=1.51; CI95 1.24, 1.83; P<0.0001; I2=28%), specifically CD2 (RR=1.82; CI95 1.30, 2.54; P=0.0004; I2=26%) and longer hospital stay (MD 2.57; 2.18, 2.96; P<0.00001; I2-98%). No difference was observed regarding operative time. CONCLUSIONS: RIRS repeated up to two times is equivalent to PCNL in terms of the SFR and may have the same safety.
- Comparing outcomes of single-use vs reusable ureteroscopes: a systematic review and meta analysis(2024) BELKOVSKY, Mikhael; PASSEROTTI, Carlo Camargo; MAIA, Ronaldo Soares; ARTIFON, Everson Luiz de Almeida; OTOCH, Jose Pinhata; CRUZ, Jose Arnaldo Shiomi DaFlexible ureterolithotripsy is a frequent urological procedure, usually used to remove stones from the kidney and upper ureter. Reusable uretero-scopes were the standard tool for that procedure, but recent concerns related to sterility and maintenance and repair costs created the opportunity to develop new technologies. In 2016, the first single-use digital flexible ureteroscope was introduced. Since then, other single-use ureteroscopes were developed, and studies compared them with the reusable ureteroscopes with conflicting results. The purpose of this study is to describe the literature that compares the performance of single-use and reusable flexible ureteroscopes in retrograde intrarenal surgery for urinary stones. A Systematic Review was performed in October 2022 in accordance with the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA). A search in MEDLINE, EMBASE, Web of Science, Google Scholar and LILACS retrieved 10,039 articles. After screening, 12 articles were selected for the Meta-Analysis. No differences were found in stone-free rate (OR 1.31, CI 95% [0.88, 1.97]), operative time (MD 0.12, CI 95% [-5.52, 5.76]), incidence of post-operative fever (OR 0.64, CI 95% [0.22, 1.89]), or incidence of post-operative urinary tract infection (OR 0.63 CI 95% [0.30, 1.32]). No differences were observed in the studied variables. Hence, the device choice should rely on the availability, cost analysis and surgeons' preference.
