Sex hormones and the total testosterone:estradiol ratio as predictors of severe acute respiratory syndrome coronavirus 2 infection in hospitalized men.

BACKGROUND: The predictive ability of the early determination of sex steroids and the total testosterone:estradiol ratio for the risk of severe coronavirus disease 2019 or the potential existence of a biological gradient in this relationship has not been evaluated. OBJECTIVES: To assess the relationship of sex steroid levels and the total testosterone:estradiol ratio with the risk of severe acute respiratory syndrome coronavirus 2 infection in men, defined as the need for intensive care unit admission or death, and the predictive ability of each biomarker. MATERIALS AND METHODS: This was a prospective observational study. We included all consecutive adult men with severe acute respiratory syndrome coronavirus 2 infections in a single center admitted to a general hospital ward or to the intensive care unit. Sex steroids were evaluated at the centralized laboratory of our hospital. RESULTS: We recruited 98 patients, 54 (55.1%) of whom developed severe coronavirus disease in 2019. Compared to patients with nonsevere coronavirus disease 2019, patients with severe coronavirus disease 2019 had significantly lower serum levels of total testosterone (111 ± 89 vs. 191 ± 143 ng/dL; p < 0.001), dehydroepiandrosterone (1.69 ± 1.26 vs. 2.96 ± 2.64 ng/mL; p < 0.001), and dehydroepiandrosterone sulfate (91.72 ± 76.20 vs. 134.28 ± 98.261 µg/dL; p = 0.009), significantly higher levels of estradiol (64.61 ± 59.35 vs. 33.78 ± 13.78 pg/mL; p = 0.001), and significantly lower total testosterone:estradiol ratio (0.28 ± 0.31 vs. 0.70 ± 0.75; p < 0.001). The lower the serum level of androgen and the lower the total testosterone:estradiol ratio values, the higher the likelihood of developing severe coronavirus disease 2019, with the linear trend in the adjusted analyses being statistically significant for all parameters except for androstenedione (p = 0.064). In the receiver operating characteristic analysis, better predictive performance was shown by the total testosterone:estradiol ratio, with an area under the curve of 0.77 (95% confidence interval 0.68-0.87; p < 0.001). DISCUSSION AND CONCLUSION: Our results suggest that men with severe acute respiratory syndrome coronavirus 2 infection, decreased androgen levels and increased estradiol levels have a higher likelihood of developing an unfavorable outcome. The total testosterone:estradiol ratio showed the best predictive ability.

Results of fusion prostate biopsy comparing with cognitive and systematic biopsy.

PURPOSE: Our study aims to determine whether there are differences in the degree of detection of prostate cancer (PCa) and CsPCa between fusion prostate biopsy (FPB), cognitive biopsy (PCB), and randomized, systematic biopsy (SB). METHODS: A retrospective analysis was carried out of 195 patients with suspected PCa at the San Cecilio University Clinical Hospital in Granada who underwent a prostate biopsy between January and December 2021. Patients were divided into three groups: group 1, patients undergoing FPB transperineally with ultrasound BK 3000 (N = 87); group 2, PCB (N = 59) transperineally; and group 3, transrectal SB (N = 49), the latter two, with an ultrasound BK Specto. RESULTS: We found differences in favor of image-directed biopsies (FPB and PCB) with a percentage of positive biopsies of 52.8% and 50%, respectively, compared to 41.4% with SB, but without these differences being significant. Given the controversy in performing prostate biopsies in PI-RADS 3 lesions reported in the literature, a subanalysis was performed excluding the FPB performed for PI-RADS 3 lesions (PI-RADS 4 and 5 are included), finding significant differences when comparing FPB with PCB and SB (group 1, 64% vs group 2, 45.8%; p = 0.05) (group 1, 64% vs group 3, 42.9%; p = 0.035). CONCLUSION: With the results obtained in our series, we conclude that the finding of a PI-RADS 3 lesion in mpMRI should not be an absolute criterion to indicate prostate biopsy. On the other hand, for PI-RADS 4 and 5 lesions, FPB is recommended, which in this case turns out to be superior to PCB and SB.

A randomized, double-blind, placebo-controlled clinical trial of the use of hydroxycitric acid adjuvant to shock wave lithotripsy therapy in patients with calcium stones. Stone fragmentation results.

Our objective was to improve the results of extracorporeal shock waves lithotripsy using hydroxycitric acid (HCA) like adjuvant therapy. Double blind randomized clinical trial using hydroxycitric acid versus placebo (ID NCT05525130). Multicenter study of adjuvant exposure to a food supplement with hydroxycitric acid (HCA), vs. placebo in patients with calcium oxalate and calcium phosphate lithiasis with indication for extracorporeal shock wave lithotripsy (ESWL). 81 patients were included in the study to compare the effect of HCA versus placebo. Stone fragmentation, the main efficacy variable. Other variables analyzed were stone size, Hounsfield Unit Stone and tolerability. Statistical study with SPSS, statistical significance p ≤ 0.05. Eighty-one patients were included, 40 in the intervention group with HCA and 41 in the control group with placebo. The average stone area was 174,36 mm2 (SD: 32,83 mm2) and the average hardness was 1128,11 (SD: 257,65), with no statistically significant differences between groups. Significant statistical differences were obtained in the analysis of the population by intention to treat and by protocol of the main variable, no fragmentation vs. fragmentation where 100% of the patients, who were given ESWL and took HCA, presented fragmentation while 17% of the patients with placebo did not reach fragmentation (p = 0.03). The adjuvant use of HCA in patients for whom ESWL has been indicated, facilitates stone fragmentation in all cases, which is not achieved in up to 17% of the patients who did not use HCA. We recommend the use of HCA in patients prior to shock wave treatment to improve their fragmentation in calcium stones.

[Adaptation of surgery practice during the Covid-19 pandemic. Ureteroscopy in outpatient surgery.] / Ureterorrenoscopias en régimen ambulatorio. Adaptación del protocolo por la pandemia Covid-19.

OBJECTIVE: The World Health Organizationdeclared a pandemic status due to the COVID-19 disease caused by the new coronavirus SARS-Cov-2 in March 2020. This caused high health pressure that hashad an impact on the Spanish National Health System and Granada has been one of the most affected provincesnationwide. The high healthcare pressure derived from it has had an impact on the National Health System throughout the Spanish territory, with Granada beingone of the most affected provinces nation wide. The increase in the admissions of patients with COVID-19 in such a short time has forced us to optimize hospital resources, prioritizing them in patients with COVID-19 and oncological or urgent pathology. In this context, the increasingly frequent and recurrent lithiasis is treated conservatively. However, the prolongation of the pandemic situation poses the challenge of offering definitive treatment to these patients. MATERIAL AND METHODS: We present the rearrangement performed in our Lithotripsy Unit with the aim of developing a comprehensive and alternative protocol for performing ureteroscopies on an outpatient basis, assuming the patient from admission to hospital discharge, with the collaboration of the Anesthesiology service. RESULTS: In this new protocol, 35 ureteroscopies were performed without noticing intraoperative complications or during the recovery period developed in the Day Hospital integrated within the Lithotripsy Unit. CONCLUSIONS: The redistribution of our resources has allowed us to continue performing ureterorenoscopies on an outpatient basis without the need to use hospital beds and reducing the traffic of patients within the hospital itself with an adequate safety profile.

OBJETIVO: En marzo de 2020, la organización mundial de la salud declaró el estado de pandemia por la enfermedad COVID-19 ocasionada por el nuevo coronavirus SARS-Cov-2. La alta presión asistencial derivada de la misma, ha repercutido en el Sistema Nacional de Salud en todo el territorio español, siendo Granada una de las provincias más afectadas a nivel nacional. El aumento de ingresos de pacientes con esta enfermedad en tan corto periodo de tiempo, nos ha obligado a optimizar los recursos hospitalarios priorizándolos en los pacientes afectos de COVID-19 y patología oncológica o urgente. En este contexto, la enfermedad litiásica, cada vez más frecuente y recurrente es manejada de forma conservadora. Sin embargo, la prolongación en el tiempo de la situación de pandemianos plantea el reto de ofrecer un tratamiento definitivoa estos pacientes. MATERIAL Y MÉTODOS: Exponemos la reordenaciónrealizada en nuestra Unidad de Litotricia con el objetivode desarrollar un protocolo integral y alternativo derealización de ureteroscopias en régimen ambulatorioasumiendo el paciente desde su ingreso hasta su altahospitalaria, con la colaboración del servicio de Anestesiologíay Reanimación. RESULTADOS: Se realizan 35 ureteroscopias en estenuevo protocolo sin advertir complicaciones intraoperatoriasni durante el periodo de recuperación desarrolladoen el Hospital de Día integrado dentro de la Unidadde Litotricia. CONCLUSIONES: La redistribución de nuestros recursosnos ha permitido continuar realizando de maneraordinaria ureterorrenoscopias en régimen ambulatoriosin necesidad de usar camas de hospitalización y disminuyendoel tránsito de pacientes dentro del propiohospital con un adecuado perfil de seguridad.

Preliminary case control description.] / Evaluación del tratamiento de litiasis renal radiopaca mediante la combinación de litotricia extracorpórea por ondas de choque y Fagolitos Plus®. Estudio preliminar de casos y controles.

INTRODUCTION: The nutritional supplement called Fagolitos plus® contains hydroxycitric acid as main component, in addition to zinc, magnesium, vitamin A and vitamin B6. It is necessary to study new molecules as chemolytic treatment in calcium lithiasis or that facilitate its fragmentation with the help of other instrumental treatments. OBJECTIVE: The objective of this study is to evaluate the effectiveness of the combined treatment of Fagolitos plus® and extracorporeal lithotripsy in the fragmentation of the lithiasis. MATERIAL AND METHODS: Retrospective case-control study includes 88 patients with lithiasis. Group 1: Treated with 1 session of extracorporeal lithotripsy and Fagoliths plus®. Group 2: Treated with 1 session of extracorporeal lithotripsy. The variables analyzed were: Age, sex, body mass index, maximum diameter of the stone, area of the stone, hounsfield units of the stone measured by axial tomography, location of the stone, result after 1 session of extracorporeal wave lithotripsy shock [complete fragmentation, partial fragmentation (presence of a fragment greater than 5 mm) and absence of fragmentation (same size of the lithiasis)], adverse effects that occurred after taking Fagolitos plus®, days of treatment with Fagolitos plus® and energy shock wave applied to lithiasis. Results were analyzed with SPSS 20.0, p≤0.05. RESULTS: The mean age of the patients included in the study is 53.81 ± 12.62 years in group 1 compared to 56.53 ± 12.37 years in group 2, p=0.31. According to the distribution by sex, there were no statistically significant differences (p=0.5), including 24 men and 24 women in group 1 and 23 men and 17 women in group 2. The mean of body mass index of the patients in group 1 was 28.39 ± 2.27 kg/m2 in group 1 versus 28.39 ± 3.03 kg/m2 in group 2, p=0.9. The maximum diameter of the stone was 11.5 ± 3.91 mm in group 1 compared to 13.15 ± 5.49 mm in group 2, p=0.1. The area of the lithiasis measured by tomography was 104.74 ± 70.56 mm2 in group 1 compared to 141.91 ± 80.95 mm2 in group 2, p=0.3. The Hounsfield units measured by tomography of the lithiasis in group 1 was 1061.98 ± 213.68 compared to 1143.15 ± 172.24 in group 2, p=0.06. Relation to fragmentation, complete fragmentation was observed in 66.7% of group 1 patients, compared to 41% of group 2 patients (p=0.02), between 20-30 days after the first session of Extracorporeal Lithotripsy evaluated by means of a simple X-ray of the Abdomen. CONCLUSIONS: The administration of Fagolitos plus® concomitant to extracorporeal lithotripsy could increase its effectiveness in lithiasis fragmentation, requiring clinical trials and prospective studies to confirm these findings.

Clinical characteristics and outcome of bacteraemia caused by Enterobacter cloacae and Klebsiella aerogenes: more similarities than differences.

OBJECTIVES: The genus Enterobacter is a common cause of nosocomial infections. Historically, the most frequent Enterobacter species were those of Enterobacter cloacae complex and Enterobacter aerogenes. In 2019, E. aerogenes was re-classified as Klebsiella aerogenes owing to its higher genotypic similarity with the genus Klebsiella. Our objective was to characterise and compare the clinical profiles of bacteraemia caused by E. cloacae and K. aerogenes. METHODS: This 3-year multicentre, prospective cohort study enrolled consecutive patients with bacteraemia by E. cloacae or K. aerogenes. Baseline characteristics, bacteraemia features (source, severity, treatment), antibiotic susceptibility, resistance mechanisms and mortality were analysed. RESULTS: The study included 285 patients with bacteraemia [196 (68.8%) E. cloacae and 89 (31.2%) K. aerogenes]. The groups showed no differences in age, sex, previous use of invasive devices, place of acquisition, sources or severity at onset. The Charlson score was higher among patients with E. cloacae bacteraemia [2 (1-4) vs. 1 (0.5-3); P = 0.018], and previous antibiotic therapy was more common in patients with K. aerogenes bacteraemia (57.3% vs. 41.3%; P = 0.01). Mortality was 19.4% for E. cloacae and 20.2% for K. aerogenes (P = 0.869). Antibiotic susceptibility was similar for both species, and the incidence of multidrug resistance or ESBL production was low (6% and 5.3%, respectively), with no differences between species. CONCLUSION: Bacteraemias caused by E. cloacae and K. aerogenes share similar patient profiles, presentation and prognosis. Patients with E. cloacae bacteraemia had more co-morbidities and those with K. aerogenes bacteraemia had received more antibiotics.

A prospective, multicenter case control study of risk factors for acquisition and mortality in Enterobacter species bacteremia.

BACKGROUND: Enterobacter is among the main etiologies of hospital-acquired infections. This study aims to identify the risk factors of acquisition and attributable mortality of Enterobacter bacteremia. METHODS: Observational, case-control study for risk factors and prospective cohort for outcomes of consecutive cases with Enterobacter bacteremia. This study was conducted in five hospitals in Spain over a three-year period. Matched controls were patients with negative blood cultures and same sex, age, and hospitalization area. RESULTS: The study included 285 cases and 570 controls. E. cloacae was isolated in 198(68.8%) cases and E. aerogenes in 89(31.2%). Invasive procedures (hemodialysis, nasogastric tube, mechanical ventilation, surgical drainage tube) and previous antibiotics or corticosteroids were independently associated with Enterobacter bacteremia. Its attributable mortality was 7.8%(CI95%2.7-13.4%), being dissimilar according to a McCabe index: non-fatal=3.2%, ultimately fatal=12.9% and rapidly fatal=0.12%. Enterobacter bacteremia remained an independent risk factor for mortality among cases with severe sepsis or septic shock (OR 5.75 [CI95%2.57-12.87], p<0.001), with an attributable mortality of 40.3%(CI95%25.7-53.3). Empiric therapy or antibiotic resistances were not related to the outcome among patients with bacteremia. CONCLUSIONS: Invasive procedures, previous antibiotics and corticosteroids predispose to acquire Enterobacter bacteremia. This entity increases mortality among fragile patients and those with severe infections. Antibiotic resistances did not affect the outcome.

OBJECTIVES: Extracorporeal shock wave lithotripsy is a minimally invasive therapeutic option for the treatment of renal-ureteral lithiasis. The aim of this study was to analyze the results and complications of shock wave extracorporeal lithotripsy treatment with the Dornier Gemini® Generator EMSE 220f-XXP device in patients with renal and ureteral lithiasis. MATERIAL AND METHODS: Retrospective study including 377 patients with renal or ureteral lithiasis with indication for treatment with extracorporeal shock wave lithotripsy. The following variables were analyzed, age, sex, body mass index, lithiasis size, lithiasis location, presence of urinary diversion, number of lithotripsy sessions, number of shock waves, fluoroscopy time, wave energy, applied focal energy coefficient, efficiency coefficient, lithiasic fragmentation, lithiasic clearance, residual lithiasis, presence of lithiasis and complications. The results were analyzed with SPSS 17.0 considering statistical significance p≤0.05. RESULTS: Of the 377 patients, 213 were men and 164 women, with a mean age of 51.28 ± 12.77 years. The mean size of the stones in maximum diameter was 11.77 ± 6.13 mm. Lithiasis fragmentation occurred in 81.9% of cases, with a percentage of residual lithiasis after the first session of 58.7% and a total or partial expulsion rate of lithiasis fragments of 68.3%, with global success at the end of sessions of lithotripsy of 69.8%. The overall Efficiency Ratio was 0.42, higher in upper calyx 0.51 and lower in medium calyx 0.35, with significant differences (p<0.05). The only differences were found in relation to the success of lithotripsy treatment (75% versus 64.6%, p=0.02), according to lithiasis size (≤10 mm maximum diameter in comparison to >10 mm). In patients with a DJ catheter there is a higher percentage of residual lithiasis (p=0.006). CONCLUSIONS: Treatment with extracorporeal lithotripsy in small lithiasis and in well-selected patients obtains good results with a low rate of complications regardless of sex and body mass index.

The aim of this study was to analyze the results and complications of shock wave extracorporeal lithotripsy treatment with the Dornier Gemini (R) Generator EMSE 220f-XXP device in patients with renal and ureteral lithiasis. Material and methods: Retrospective study including 377 patients with renal or ureteral lithiasis with indication for treatment with extracorporeal shock wave lithotripsy. The following variables were analyzed, age, sex, body mass index, lithiasis size, lithiasis location, presence of urinary diversion, number of lithotripsy sessions, number of shock waves, fluoroscopy time, wave energy, applied focal energy coefficient, efficiency coefficient, lithiasic fragmentation, lithiasic clearance, residual lithiasis, presence of lithiasis and complications. The results were analyzed with SPSS 17.0 considering statistical significance p≤0.05. RESULTS: Of the 377 patients, 213 were men and 164 women, with a mean age of 51.28 ± 12.77 years. The mean size of the stones in maximum diameter was 11.77 ± 6.13 mm. Lithiasis fragmentation occurred in 81.9% of cases, with a percentage of residual lithiasis after the first session of 58.7% and a total or partial expulsion rate of lithiasis fragments of 68.3%, with global success at the end of sessions of lithotripsy of 69.8%.The overall Efficiency Ratio was 0.42, higher in upper calyx 0.51 and lower in medium calyx 0.35, with significant differences (p<0.05). The only differences were found in relation to the success of lithotripsy treatment (75% versus 64.6%, p=0.02), according to lithiasis size (≤10 mm maximum diameter in comparison to >10 mm). In patients with a DJ catheter there is a higher percentage of residual lithiasis (p=0.006). Conclusions: Treatment with extracorporeal lithotripsy in small lithiasis and in well-selected patients obtains good results with a low rate of complications regardless of sex and body mass index

Ocular Kinematics Measured by In Vitro Stimulation of the Cranial Nerves in the Turtle.

After animals are euthanized, their tissues begin to die. Turtles offer an advantage because of a longer survival time of their tissues, especially when compared to warm-blooded vertebrates. Because of this, in vitro experiments in turtles can be performed for extended periods of time to investigate the neural signals and control of their target actions. Using an isolated head preparation, we measured the kinematics of eye movements in turtles, and their modulation by electrical signals carried by cranial nerves. After the brain was removed from the skull, leaving the cranial nerves intact, the dissected head was placed in a gimbal to calibrate eye movements. Glass electrodes were attached to cranial nerves (oculomotor, trochlear, and abducens) and stimulated with currents to evoke eye movements. We monitored eye movements with an infrared video tracking system and quantified rotations of the eyes. Current pulses with a range of amplitudes, frequencies, and train durations were used to observe effects on responses. Because the preparation is separated from the brain, the efferent pathway going to muscle targets can be examined in isolation to investigate neural signaling in the absence of centrally processed sensory information.

Risk of renal stone formation in patients treated with luteinising hormone-releasing hormone analogues for prostate cancer: importance of bone metabolism and urine calcium.

PURPOSE: To determine whether androgen blockade produces metabolic changes in urine and increases the risk of calculi after 1 year of treatment. MATERIALS AND METHODS: The study included 38 patients, from the period April 2015 to June 2016, diagnosed with locally advanced prostate cancer or lymph node metastasis, and with an indication of androgen blockade. Androgen blockade was started with luteinising hormone-releasing hormone (LHRH) analogues, and a blood specimen, a fasting urine and 24-h urine were collected at the time of inclusion, and then at 1 year of follow-up. A study was performed at baseline and at 1 year with imaging tests. An analysis of the variables was performed with a p ≤ 0.05 considered as statistically significant. RESULTS: The mean age of the patients included in the study was 72.26 ± 6.75 years. As regards the biochemistry parameters, an increase in osteocalcin (from 16.28 ± 9.48 to 25.56 ± 12.09 ng/ml; p = 0.001) and an increase in ß-crosslaps (from 0.419 ± 0.177 to 0.743 ± 0.268 ng/ml; p = 0.0001) were observed. In the urinary parameters, a significant increase was observed in the fasting calcium/creatinine ratio (from 0.08 ± 0.06 to 0.13 ± 0.06; p = 0.002) and in the 24-h calcium renal excretion (from 117.69 ± 66.92 to 169.42 ± 107.18 mg; p = 0.0001). Calculi formation was observed in 12 of the 38 patients included (31.6%), with a mean size of 3.33 ± 1.31 mm. CONCLUSION: Treatment with LHRH analogues, as well as increasing the appearance of metabolic syndrome and speeding up the loss bone mineral density, causes an increase in fasting urine calcium.

Deprivación androgénica en cáncer de próstata y riesgo de aparición de litiasis renal. Resultados de un estudio de casos y controles / Androgen deprivation therapy in prostate cancer and risk of developing renal calculi: Results of a case-control study

Antecedentes y objetivo: El tratamiento de privación androgénica en el cáncer de próstata se asocia a la aparición de diferentes efectos adversos, entre los que se encuentran la osteoporosis y el síndrome metabólico. Ambos están relacionados con la aparición de nefrolitiasis. El objetivo de este estudio es analizar la aparición de nefrolitiasis en pacientes sometidos a este tratamiento con análogos LHRH. Pacientes y métodos: Estudio de casos y controles en el que se incluyeron un total de 85 pacientes divididos en 2 grupos: el grupo 1 estaba formado por 41 pacientes con tratamiento de privación androgénica y el grupo 2 por 44 pacientes sin tratamiento de privación androgénica. Resultados: En el grupo 1 se produjo litiasis de nueva aparición en 12 casos (29,3%) frente a 2 casos en el grupo 2 (4,5%) (p = 0,0001), a los 4,4 años de comenzar el tratamiento de privación androgénica. La odds ratio estimada fue de 8,69 (IC al 95% 1,81-41,76). Conclusión: Parece existir relación entre el tratamiento con análogos LHRH y la litiasis; no obstante, son precisos estudios prospectivos a largo plazo con control metabólico para poder establecer las causas que expliquen la aparición de este fenómeno (AU)

Background and objective: Androgenic deprivation therapy in prostate cancer is associated with the onset of different adverse effects, including osteoporosis and metabolic syndrome. Both are related to the onset of nephrolithiasis. The objective of this article is to study the incidence of renal stones in patients undergoing androgen deprivation therapy with LHRH analogue. Patients and methods: Case-control study including a total of 85 patients divided into 2 groups: group 1, with 41 patients on androgen deprivation therapy, and group 2, with 44 patients not receiving androgen deprivation therapy. Results: New-onset lithiasis was observed in 12 cases (29.3%) in group 1 compared to 2 cases (4.5%) in group 2 (P = .0001), 4.4 years after starting the androgen deprivation therapy. The estimated odds ratio was 8.69 (95% CI 1.81-41.76). Conclusion: The incidence of renal stones could be increased in patients receiving treatment with analogue LHRH. However, long-term prospective studies with a metabolic control are required to be able to establish the causes explaining the development of this phenomenon in patients undergoing treatment with androgen deprivation therapy (AU)

The Effect of Antibiotic Prophylaxis on Post-Operative Infection in Patients Undergone Flexible Cystos-copy.

PURPOSE: The aim of this study is to determine whether antibiotic prophylaxis is required in this outpatient procedure. MATERIALS AND METHODS: A non-randomised, prospective observational study that included 184 patients subjected to flexible cystoscopy divided into three groups: - Group 1:60 patients with prophylaxis of 500 mg of ciprofloxacin;- Group 2:62 patients with prophylaxis of 3 g of phosphomycin; and Group 3:62 without antibiotic prophylaxis. Prior to inclusion in the study, absence of infection was checked by means of a urine culture obtained 7 days before the procedure. An analysis was made of urinary infection after 7 days, the cystoscopy indications and its diagnosis, the presence of comorbidities, and the urinary symptoms during the following 7 days. RESULTS: The mean age of the patients in Group 1 was 65.3 (SD: 12.5) years, 66.7 (10.8) years in Group 2, and 66.9 (10.8) years in Group 3 (P = .7). Bacteriuria was present in 15% of the patients in Group 1, compared to 22.6% in Group 2, and 12.9% in Group 3, with the differences not statistically significant. In multivariate analysis, it was observed that there was no association with the appearance of bacteriuria between the groups for age (P = .8), diabetes (P = .2), smoking (P = .4), lower urinary tract symptoms (P = .7), or immunosuppression (P = .6). CONCLUSION: The use of ciprofloxacin or phosphomycin as prophylaxis does not appear to be indicated in flexible cystoscopy in our health area.
