Comparative analysis of the performance of two automated hematological platforms in a level III-I Hospital of the MINSA-Peru in 2023
(Universidad Privada Norbert Wiener, 2024-06-09) Basilio Córdova, Deisy Sumiela; Huamán Cárdenas, Victor Raul
Objective: To compare the analytical performance of the two hematological platforms Beckman Coulter DxH 900 and Mindray BC 6200 used in a level III-I Hospital in Minsa-Peru 2023. Materials and Methods: Based on the CLSI EP15-A3(1) guide, 5 replicates will be performed for each control level over 5 consecutive days, totaling 25 runs per level for leukocytes, erythrocytes, hemoglobin, and platelets. Based on the CLSI EP6-A(2) guide, 5 samples with equidistant concentrations will be tested 3 times for leukocytes and platelets. Results: On the Beckman Coulter DxH900 platform, the Sigma values are 10.9 for leukocytes, 4.6 for erythrocytes, 5.3 for hemoglobin, and 8.1 for platelets. The results for %CVWL(Lab) were lower than the %CVWL(Fab), thus the verification is accepted for each analyte. The overall precision determination for each analyte was based on the limiting level, so the imprecision is 1.5 for leukocytes, 0.8 for erythrocytes, 0.6 for hemoglobin, and 1.6 for platelets. For the Mindray BC6200 platform, the Sigma values are 6.5 for leukocytes, 8.5 for erythrocytes, 7.4 for hemoglobin, and 4.6 for platelets. The %CVWL(Lab) results were lower than the %CVWL(Fab), so the verification is accepted for each analyte. However, the %CVR(Lab) for platelets was rejected at level 1 because it exceeded the %CVR(Fab) and accepted for other levels, but the intralaboratory condition is considered acceptable. The overall precision determination for each analyte was based on the limiting level, with imprecision of 1.6 for leukocytes, 0.7 for erythrocytes, 0.3 for hemoglobin, and 4.8 for platelets. Conclusions: Both platforms met the manufacturer's accuracy and precision specifications, with a favorable Sigma, considering that both platforms worked with the same short quality requirement (VBD). The Beckman platform performed better compared to the Mindray platform.

Efficacy of continuous bladder irrigation in the management of Hematuria
(Universidad Privada Norbert Wiener, 1905-07-09) Rojas Reyes, Luz; Sanchez Espejo, Eloisa Ada; Gómez Gonzales, Walter Edgar
Objective: Determine the effectiveness and uses of continuous bladder irrigation in the management of urological events. Materials and methods: Systematic Reviews are an observational and retrospective research design, which synthesizes the results of multiple primary investigations. They are an essential part of evidence-based nursing due to their rigorous methodology, identifying relevant studies to answer specific questions of clinical practice. Results: The reviewed articles were found in the databases Scielo, Dialnet, Ebsco, Lilacs, the results show that there is a lower incidence of immediate postoperative complications inherent to the operation of the urethrovesical catheter, in patients left without irrigation, likewise the average day in the hospital stay of these patients was shorter, concluding that continuous bladder irrigation as a post-prostatectomy treatment is not essential. The other authors also agree that the use of continuous bladder irrigation as a treatment using a continuous antibiotic regimen is recommended. Conclusions: The reviewed articles show that continuous bladder irrigation as a post-prostatectomy treatment and intervention is not essential in patients. The use of continuous bladder irrigation as a treatment using a continuous antibiotic regimen is recommended, it reduces hospital stay, reduces fever and quickly improves the patient's general conditions as well as making cultures negative in a shorter period of time. The management of hematuria of bladder origin through continuous bladder irrigation as a treatment with the application of intravesical bismuth solution is effective in shortening the time of hematuria control.

Most frequent postoperative complications of Prostatic Adenomectomy in urological patients
(Universidad Privada Norbert Wiener, 1905-07-09) Gonzales Guillén, Graciela; Colcas Vargas, Nuve Sixta; Mendigure Fernández, Julio
Objective: Determine the most frequent postoperative complications of prostate adenomectomy. Material and methods: Systematic review of 10 selected articles, using the database Pubmed, Elsevier, Sciencedirect, Scielo, Redalyc, dialnet. It is a quantitative study with a descriptive, retrospective, prospective comparative, analytical and cross-sectional design. Results: The most frequent postoperative complications of adenomectomy are that 90% (n = 9/10) are urinary tract infection. 70% (n = 7/10) are urinary retention and hematuria or bleeding. The complications that represent 50% (n = 5/10) are urinary incontinence, urethral stricture, surgical wound infection, epididymitis and surgical revision. 20% (n = 2/10) is urinary fistula. Conclusion: The main factors associated with complications are urinary tract infection, urinary retention and hematuria or bleeding.

Status of the role of clinical laboratories in the assessment of dysmorphic red blood cells in urinary sediment, Lima - 2023
(Universidad Privada Norbert Wiener, 2023-10-01) Benites Ricra, Miguel Angel; Saldaña Orejón, Italo Moisés
Hematuria is defined by the presence of red blood cells in elevated quantities observed microscopically in the urinary sediment. The dysmorphic (abnormal) characteristic of the red blood cell in urine is a result of its passage through the glomerulus, indicating glomerular-origin hematuria. The initial diagnostic test should include microscopic examination of urinary sediment, the count of red blood cells observed per mm3, and the correct identification of the red blood cell morphology, either normal (biconcave) or dysmorphic with deterioration or deformation, such as vesicles or blisters on the red blood cell membrane, which indicates glomerular-origin hematuria. Currently, only international studies have shown the lack of standardization in methods for detecting and quantifying hematuria, and even difficulties in distinguishing non-glomerular hematuria from glomerular hematuria, as well as recognizing and categorizing dysmorphic red blood cell morphology, leading to discrepancies in clinical laboratories and suboptimal diagnoses.
