ABSTRACT
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.

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.

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.

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)

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.

En este artículo de revisión se analizan los principios etiopatogénicos de la formación de la litiasis urinaria. A nivel renal, como consecuencia de procesos que lesionan el urotelio se producen calcificaciones a nivel de la papila y de los conductos de Bellini que pueden ser causantes de la formación del cálculo renal. Con la mejora de las pruebas de imagen, fundamentalmente micro-TAC es posible detectarlas y podemos ser capaces de anticiparnos a la formación de la litiasis. Como bien conocemos, existen diferentes factores que influyen en la formación del cálculo y que dependerán de la composición de la misma. En la litiasis cálcica es fundamental reseñar la modificación de los tipos de hipercalciuria, actualmente distinguimos dos tipos en lugar de tres, gracias al cociente calcio/creatinina de ayunas, diferenciándose hipercalciuria absortiva e hipercalciuria de ayunas. En la hipercalciuria de ayunas es importante destacar la relación que existe entre este factor y la pérdida de densidad mineral ósea en pacientes con litiasis renal cálcica recidivante, siendo por tanto preceptivo el estudio del metabolismo óseo mediante marcadores de remodelado óseo y densitometría ósea en este tipo de pacientes. Respecto a los otros factores que intervienen en la formación de la litiasis cálcica debemos hacer especial hincapié en la hipercalciuria y su creciente aumento por su relación con la obesidad y el síndrome metabólico, así como la hipocitraturia, presente en un porcentaje importante de pacientes y relacionada en algunos casos con acidosis metabólica y también osteopenia-osteoporosis. Con respecto a la litiasis de ácido úrico hay que destacar que el pH urinario es el factor más determinante y que por tanto el control y las modificaciones del mismo serán fundamentales en la prevención de este tipo de litiasis. En la litiasis infectiva es obligatorio la presencia de gérmenes que desdoblen la urea, generándose iones de amonio, capaces de lesionar el urotelio y de formar litiasis de fosfato amónico magnésico fundamentalmente. En cuanto a la litiasis de cistina, poco frecuente, clásicamente dividida en 3 tipos, ha pasado a dividirse en tipo A y B en función del gen mutado y resulta más útil su medición directa en orina de 24 horas que realizar test de screening que tienen baja sensibilidad. En líneas generales, hemos tratado de dar una visión de conjunto de los diferentes tipos de litiasis haciendo hincapié en aquellos puntos más interesantes desde el punto de vista clínico para el urólogo
In this review, we analyze the etiopathogenic principles of urinary lithiasis formation. In the kidney, calcifications that may cause renal lithiasis are produced as a consequence of processes that injury the urothelium at the papilla and Bellini´s ducts. With the improvement of imaging techniques, mainly micro CT scan, it is possible to detect them and we may be able to anticipate to the formation of lithiasis. As we well know, there are different factors that influence the formation of the calculi depending on their composition. In calcium lithiasis it is key to review the modification of the categories of hypercalciuria, we currently distinguish two types instead of three, thanks to the fasting calcium/ creatinine ratio, differentiating absorptive hypercalciuria and fasting hypercalciuria. In the fasting hypercalciuria, it is important to emphasize the relationship between this factor and the loss of bone mineral density in patients with recurrent renal calcic lithiasis, so that in this kind of patients it is compulsory the study of bone metabolism by bone remodelling markers and bone densitometry. Regarding the other factors that participate in the formation of calcium lithiasis we should specially emphasize on hypercalciuria and its growing increase because of its relationship with obesity and metabolic syndrome, as well as hipocitraturia, present in an important percentage of patients and related in some cases with metabolic acidosis and osteopenia-osteoporosis too. In relation to uric acid lithiasis it should be highlighted that urinary pH is the most determinant factor and, therefore, its control and modifications would be paramount for prevention of this type of lithiasis. In the infectious lithiasis, the presence of germs that split urea is mandatory. They generate ammonia ions with the ability to injure the urothelium and to form magnesium ammonium phosphate lithiasis mainly. Regarding cystine lithiasis, rare, it was classically divided in three types and now passed to be classified in type A and B depending on the muted gene, and it is more useful to perform direct 24-hour urine measurement than screening tests which have low sensitivity. In general, we tried to give a comprehensive view of the various types of lithiasis emphasizing the most interesting clinical points for the urologist

OBJETIVO: La uretrocistoscopia flexible es un procedimiento que se realiza de rutina en urología para el seguimiento de tumores vesicales y como diagnóstico en pacientes con síntomas del tracto urinario inferior y hematuria entre otra sintomatología. El objetivo de este estudio es analizar la necesidad o no de profilaxis antibiótica en este procedimiento ambulatorio. MÉTODOS: Estudio observacional prospectivo no aleatorizado en el que se incluyen 100 pacientes divididos en dos grupos: - Grupo 1: 48 pacientes con profilaxis de 500 mg de ciprofloxacino 1 h antes de la uretrocistoscopia; - Grupo 2: 52 pacientes sin profilaxis antibiótica. Previamente a la inclusión en el estudio se comprueba ausencia de infección urinaria mediante urocultivo obtenido 3 días antes del procedimiento. Se analiza indicación de cistoscopia, resultado de cistoscopia, presencia de comorbilidades, urocultivo a los 7 días, síntomas urinarios durante los 7 días siguientes. Análisis estadístico con SPSS 20.0 y significación estadística p≤0,05. RESULTADOS: La edad media de los pacientes del grupo 1 fue de 66,7±12,4 años versus 65,6±10,8 años del grupo 2 (p = 0,6). No hubo diferencias en el porcentaje de hombres/mujeres incluidos entre los grupos. El 14% de los pacientes del grupo 1 presentó bacteriuria frente al 12% del grupo 2, sin diferencias significativas. En el estudio multivariante, se observa que ni la edad, diabetes, tabaquismo, síntomas del tracto urinario inferior ni inmunosupresión se relacionan con la aparición de bacteriuria entre grupos. CONCLUSIÓN: El uso de ciprofloxacino como profilaxis en la cistoscopia flexible no lo consideramos indicado en nuestra área de salud, ya que no disminuye la presencia de infección urinaria o bacteriuria
OBJECTIVE: The goal of this study is to analyze whether there is a need for antibiotic prophylaxis in this outpatient procedure. METHODS: Prospective observational non-randomized study including 100 patients divided into two groups: - Group 1: 48 patients receiving 500 mg of ciprofloxacin prophylaxis 1 hour before urethrocystoscopy; - Group 2: 52 patients without antibiotic prophylaxis. Before inclusion of the patients in the study, we checked the absence of urinary tract infection by means of a urinalysis obtained 3 days before the procedure. We analyze: cystoscopy indication, cystoscopy results, presence of comorbidities, urinalysis 7 days after the procedure, and urinary symptoms within 7 days of the procedure. The statistical analysis was performed using SPSS 20.0 and the statistical significance was p≤0.05. RESULTS: The average age of patients in group 1 was 66.7±12.4 versus 65.6±10.8 years in group 2 (p = 0.6). There are no differences in the percentage of men/women included in the groups. 14% of patients of group 1 and 12% of group 2 presented bacteriuria, without showing any significant differences. In the multivariate study, it is observed that neither age, nor diabetes, smoking, lower urinary tract symptoms, nor immunosuppression are related with the onset of bacteriuria in the groups. CONCLUSION: We do not consider the use of ciprofloxacin as prophylaxis for flexible cystoscopy is appropriate in this area of health, since it does not reduce the presence of urinary infection or bacteriuria

OBJETIVO: El objetivo es describir la técnica quirúrgica laparoscópica de resección en tumores malignos mayores de 10 cms. MÉTODO: Presentamos dos casos, mujer de 63 años con masa heterogénea suprarrenal izquierda de 11 cms de diámetro máximo y hombre de 80 años con masa heterogénea suprarrenal izquierda de 13 cms de diámetro máximo. En ambos casos se realiza exéresis por vía laparoscópica utilizando 4 trócares y extracción mediante retractor de heridas Alexis®. RESULTADO: En el caso de la mujer de 63 años el resultado histológico fue de angiomiolipoma epitelioide maligno, mientras que en el caso del hombre de 80 años el resultado histológico fue de carcinoma neuroendocrino de células grandes de posible origen pulmonar. CONCLUSIÓN: Pensamos que la cirugía laparoscópica de grandes masas de comportamiento maligno depende de la integridad capsular y relación con estructuras vecinas en las pruebas de imagen y no tanto del tamaño tumoral o de las características internas del tumor en las pruebas de imagen
OBJECTIVE: The aim of this article is to describe the surgical technique of laparoscopic resection in malignant tumors greater than 10 cm. METHODS: We present two cases, a 63 year old woman with a left adrenal heterogeneous mass of 11 cm in maximum diameter and an 80 year old man with a left adrenal heterogeneous mass 13 cm in maximum diameter. In both cases excision was performed laparoscopically using 4 trocars and the Alexis® wound retractor for specimen extraction. RESULTS: For the 63 year old woman, the histological result was malignant epithelioid angiomyolipoma, while in the case of the 80 year old man was large cell neuroendocrine carcinoma with possible pulmonary origin. CONCLUSIONS: We believe that laparoscopic surgery of large masses of malignant behavior depends on the capsular integrity and their relationship to adjacent structures rather than tumor size or the internal characteristics of tumor on imaging tests

ABSTRACT Introduction: The aim of this work is to study the density of the renal papillae in stone-forming patients and to determine its usefulness. Materials and Methods: This study included a total of 79 patients diagnosed with renal stones and on whom a computed tomography without contrast was performed from June 2014 to May 2015. The patients were divided into two groups: Group 1 (single episode) included 43 patients, and Group 2 (recurrent episodes) included 36 patients. The density of six renal papillae (3 per kidney) was measured, and the means obtained were compared between Groups 1 and 2. Statistical analysis was performed using SPSS 20.0. Results: The mean papillary density in Group 1 was 32.26 (SD 4.07) HU compared to 42.36 (SD 8.03) HU in Group 2 (P=00001). A ROC curve was constructed, obtaining an optimal cut-off point of 36.8HU [area under the curve, 0.881 (95% CI; 0.804-0.958); P=0001], with a sensitivity of 80% and a specificity of 90%. The relative risk was estimated at 40.3 (95% CI; 10.8-151.1), meaning that a patient with a mean papillary density greater than 36.8HU would have a 40 times greater risk of having recurrent renal stones. The positive predictive value (PPV) was 81% and the negative predictive value (NPV) was 90%. Conclusion: The measurement of renal papillary density could be useful in predicting recurrent stone-formers. These results need to be confirmed in future studies with a greater number of patients and a longer follow-up.
