Pielonefritis xantogranulomatosa: un reto actual para la laparoscopia.

OBJECTIVE: To present the results of our case series on laparoscopic nephrectomy in xanthogranulomatous pyelonephritis (XGP). METHODS: A retrospective study was conducted that included 143 patients treated with laparoscopic nephrectomy for non-functioning kidney, of whom 15 had XGP, within the time frame of 2011 to 2019. The demographic and clinical data were collected, along with the intraoperative results, complications, and days of hospital stay. RESULTS: Transperitoneal laparoscopic nephrectomy was successfully performed on 15 patients with XGP, with no need for conversion. Mean intraoperative time was 124.4 minutes (range 70-240) and intraoperative blood loss was 148.5 ml (range 30-550), with no blood transfusion required. No intraoperative complications occurred but there was one postoperative complication (6.6%), classified as Clavien-Dindo I (surgical wound infection). Mean hospital stay was 2.85 days (range 2-7). CONCLUSIONS: Nephrectomy is the definitive management for XGP, and the laparoscopic approach should be considered a treatment modality, despite the fact that the pathology involves a severe chronic inflammatory process. Its benefits are reduced surgery duration, less blood loss, a lower complication rate, and fewer days of hospital stay, when performed by a skilled and experienced surgeon.

OBJETIVO: Presentar los resultados de nuestra serie de nefrectomía laparoscópica en pielonefritis xantogranulomatosa (PXG). MÉTODO: Se realizó un estudio retrospectivo que incluyó 143 pacientes tratados con nefrectomía laparoscópica por exclusión renal, de los cuales 15 fueron por PXG, en el periodo comprendido de 2011 a 2019. Se recolectaron datos demográficos y clínicos, resultados transoperatorios, complicaciones y días de estancia hospitalaria. RESULTADOS: Se realizó nefrectomía laparoscópica transperitoneal de forma exitosa en 15 pacientes con PXG, sin necesidad de conversión. El tiempo transoperatorio promedio fue de 124.4 minutos (rango: 70-240). El sangrado transoperatorio fue de 148.5 ml (rango: 30-550), sin requerimiento de transfusión sanguínea. No se reportaron complicaciones transoperatorias; se presentó una complicación en el posoperatorio (6.6%) clasificada como Clavien-Dindo I (infección de la herida quirúrgica). La estancia hospitalaria promedio fue de 2.85 días (rango: 2-7). CONCLUSIONES: El manejo definitivo de la PXG es la nefrectomía, y el abordaje laparoscópico debe ser considerado como una modalidad de tratamiento a pesar de ser una patología que presenta un proceso inflamatorio grave y crónico, obteniéndose beneficios como disminución en el tiempo quirúrgico, menor sangrado, menor tasa de complicaciones y menos días de estancia hospitalaria cuando es realizado por un cirujano experimentado.

Association Between Testicular Microlithiasis and Histological Subtype in Testicular Cancer.

Background There is a clear association between testicular cancer and microlithiasis when there are predisposing risk factors such as the history of germ cell tumors in first-degree relatives, testicular atrophy, Klinefelter's syndrome, and cryptorchidism. This study aimed to establish an association between microlithiasis and the histological subtype of testicular cancer by analyzing data on Hispanic population. Methods A retrospective cohort, longitudinal, comparative, and analytic study was conducted on patients with a confirmed diagnosis of primary testicular cancer. The testicular ultrasounds were checked before any surgical treatment to find microlithiasis. We performed a binary logistic regression to establish an association between microlithiasis and the type of testicular cancer. Results A total of 130 clinical files were analyzed. Binary logistic regression showed no association between testicular microlithiasis and the subtype of testicular cancer (p = 0.438, 95% CI: 0.80-1.64). The result of the Pearson chi-square test showed no association (p = 0.184). We also analyzed the association between age and microlithiasis using the one-way ANOVA test (p = 0.82) and the association between age and the dichotomic subtype of testicular cancer (seminomatous and non-seminomatous) using the ANOVA one-way test, which showed no significant association in age and testicular cancer subtype (p = 0.178). Conclusions There was no association between testicular microlithiasis and the histological subtype of testicular cancer in our study. As mentioned before, we recommend conducting a more extensive study to provide further scientific evidence to establish a reliable association between microlithiasis and the subtype of testicular cancer since there is a discrepancy in the results of our study with the information previously reported. We encourage the study of characterization of risk factors among ethnic groups as this field has not been explored yet.

Advantages and Short-Term Outcomes of Laparoscopic-Assisted Renal Surgery in Elderly Patients.

OBJECTIVE: To compare the perioperative results of adult and elderly patients undergoing laparoscopic renal surgery. METHODOLOGY: Retrospective, analytical study. 448 who underwent kidney surgery for benign or malignant pathologies between 2011-2019 were included in the General Hospital of Mexico "Dr. Eduardo Liceaga". They were categorized into two groups: Group 1 <60 years and Group 2 >60 years. Descriptive statistics and bivariate analysis were performed, the calculations were performed with 95% reliability and a value of p (<0.05). RESULTS: In the group over 60 years of age, the following was found: Age: 67.1 years (60-83). IMC 28.3 kg/m2 (19-48.7). Intra and postsurgical outcomes: intraoperative bleeding = 184.4cc (5-1700). Surgical Time = 112.6min (30-240). Days of hospital stay = 2 (1-7). Complications in 2.6% (Clavien-Dindo: I = 2; II = 1), no conversion was required in any patient. There were no statistically significant differences with group 1, an exception for intraoperative bleeding. CONCLUSIONS: Our study is a pioneer in Latin America in the evaluation of the geriatric population and outcomes with laparoscopic surgery and we recommend that renal procedures with a laparoscopic approach should be considered as the best strategy in the management of benign or malignant renal pathology in geriatric patients.

Should Psychiatry Be Consulted When Facing a Self-Inflicted Foreign Body in the Urinary Tract?

Background On encountering a self-inflicted foreign body in the urinary tract, it is common that emergency physicians only consult the department of urology, and no further evaluations from other specialties are sought. Psychological conditions can also involve people with psychiatric disorders who perform self-harming or sexual practices. Many case reports of foreign bodies have been reported in the literature. However, there is little information regarding which specialties to consult in this situation within the emergency department (ED). Methodology This case series study gathered information on 10 cases from patients who attended the ED from 2005 to 2020 with the diagnosis of genital or lower urinary tract foreign body. Results In total, 10 patients were analyzed with a mean age of 37.3 (SD: ±14.1) years. Of the 10 patients, seven (70%) were males, and three (30%) were females. Overall, four (40%) patients presented with lower urinary tract symptoms (dysuria, tenesmus, hematuria, urinary frequency), five (50%) patients had a significant psychiatric history, and eight (80%) patients admitted having these practices for sexual gratification. Conclusions Foreign bodies in the lower urinary tract pose a significant challenge to ED physicians and urologists because some patients do not admit or do not recall inserting foreign bodies. Patients should be interrogated for mental illness, medication use, and a history of foreign bodies in the urinary tract or genitals during the initial evaluation. There is no consensus or screening method for such patients presenting to the ED. Hence, the use of complementary imaging studies and cystoscopy is fundamental for diagnosis. Further, it is essential to perform a psychiatric evaluation to diagnose or address any underlying psychiatric conditions that could cause this behavior.

Comparison of three analgesic drug regimens with twelfth subcostal nerve block for pain control during extracorporeal shock wave lithotripsy.

INTRODUCTION AND OBJECTIVE: Extracorporeal shock wave lithotripsy (ESWL) is the first-line treatment in the majority of cases of upper urinary tract stones. Since its introduction, attempts have been made to establish the ideal accompanying analgesic method to enable the application of shock waves of adequate duration and intensity for efficacious stone fragmentation. An open, randomized, prospective, longitudinal, comparative, and experimental clinical study was conducted to evaluate the efficacy of subcostal nerve block with lidocaine, comparing it in combination with tramadol or diclofenac for pain control during ESWL. MATERIALS AND METHODS: Seventy patients of both sexes were included in the study. Thirty-five were men and 35 were women, all above 18 years of age, with kidney stones or ureteral stones smaller than 20 mm. The patients were randomly assigned to one of the following groups: Group 1 (24 patients) Twelfth subcostal nerve block with 10 ml of lidocaine 2%, 5 min before ESWL. Group 2 (25 patients) Twelfth subcostal nerve block with 10 ml lidocaine 2% + intramuscular diclofenac sodium 45 min before ESWL. Group 3 (21 patients) Twelfth subcostal nerve block with 10 ml of lidocaine 2% + tramadol at 1 mg/Kg of weight, 45 min before ESWL. The visual analog scale (VAS) for pain was applied at minutes 10, 20, and 30 of the procedure. RESULTS: No statistically significant differences were reported by the ANOVA test for comparing the mean pain values between the three groups at minutes 10, 20, and 30 of the ESWL. There were no adverse effects. CONCLUSIONS: Even though there were no statistically significant differences between the three groups, the analgesic regimen of twelfth subcostal nerve block with lidocaine 2%, alone, was as efficacious as its combination with other analgesics and therefore can be used as a sole analgesic method during ESWL.

Relevancia del antecedente de absceso perirrenal en pacientes sometidos a nefrectomía simple retroperitoneal / Relevance of Perirenal Abscess in Patients undergoing Retroperitoneal Simple Nephrectomy

Las infecciones supurativas del riñón y del espacio perinefrítico son poco comunes, sin embargo, se asocian a una morbimortalidad elevada, afectando a ambos sexos por igual excepto los casos de absceso cortical que es 3 veces más común en el hombre que en la mujer. La incidencia se incrementa con la edad y habitualmente se asocia a uropatía obstructiva. Los abscesos renales representan 0,2% de todos los abscesos intraabdominales, de los cuales el 10% de los abscesos corticales rompen a través de la cápsula formando un absceso perinefrítico, el cual es difícil de manejar y conlleva un peor pronóstico, con una alta mortalidad a pesar de tratamiento quirúrgico oportuno

Supurative infections of the kidney and perinephritic space are rare, however, are associated with high morbidity and mortality, affecting both sexes equally except for cases of cortical abscess which is 3 times more common in men than in women. The incidence increases with age and is usually associated with obstructive uropathy. Renal abscesses represent 0.2% of all abscesses. intraabdominal, of which 10% of cortical abscesses break through the capsule forming a Perinephritic abscess, which is difficult to manage and leads to a worse prognosis, with high mortality despite prompt surgical treatment.

[Comparison of results of open simple nephrectomy secondary to lithiasis in patients with and without nephrostomy]. / Comparación de los resultados de la nefrectomía simple abierta secundaria a litiasis en pacientes con y sin nefrostomía.

BACKGROUND: Simple nephrectomy is the procedure of choice in the treatment of excluded kidneys. The purpose of this study was to describe and compare surgical results in open simple retroperitoneal nephrectomies in patients with and without nephrostomy. METHODOLOGY: 58 patients were analyzed. The demographic parameters of patients with nephrostomy were compared to patients without nephrostomy (age, gender, weight, lithium localization, transoperative variables (surgical time, transoperative bleeding) and postoperative variables (need for intensive care, need for transfusion, surgical wound infection and hospital stay days) RESULTS: Statistically significant differences were found for the variables of operative bleeding (p=0.0442), surgical time (p=0.0093), hospital stay days (p=0.0040), and transfusion requirements (p=0.0170). There were no differences in the need for intensive care (p=0.6314), transoperative complications (p=0.7414) and surgical wound infection (p=0.2762). CONCLUSIONS: The presence of a nephrostomy catheter in patients undergoing open simple nephrectomy leads to an increased risk of morbidity, with increased bleeding, surgical time, need for transfusion, and hospital stay days.

[Large benign prostatic hiperplasia]. / Hiperplasia prostática benigna de gran volumen.

BACKGROUND: the term prostatic hyperplasia is most frequently used to describe the benign prostatic growth, this being a widely prevalent disorder associated with age that affects most men as they age. The association between prostate growth and urinary obstruction in older adults is well documented. OBJECTIVE: large benign prostatic hyperplasia is rare and few cases have been published and should be taken into account during the study of tumors of the pelvic cavity. CLINICAL CASE: we report the case of an 81-year-old who had significant symptoms relating to storage and bladder emptying, with no significant elevation of prostate specific antigen. CONCLUSIONS: this is a rare condition but it is still important to diagnose and treat as it may be related to severe obstructive uropathy and chronic renal failure. In our institution, cases of large prostatic hyperplasia that are solved by suprapubic adenomectomy are less than 3%.

[Efficacy and safety of vardenafil in patients with erectile dysfunction. Results of the Mexican Multicentric Study]. / Eficacia y seguridad del vardenafil en pacientes con disfunción eréctil. Resultados del estudio multicéntrico mexicano.

UNLABELLED: The objective of the present study was to determine the efficacy and safety of a fixed dose of vardenafil in the treatment of patients with erectile dysfunction (ED). MATERIAL AND METHODS: This was an open label, prospective and multicentric trial. After a 4-week wash out period, all patients received 20 mg of vardenafil given on demand for 12 weeks. Primary efficacy variables were the erectile function domain of the International Index of Erectile Function (IIEF), answers to questions 2 and 3 of the Sexual Encounter Profile (SEP) and the Global Assessment Question (GAQ). All adverse events were recorded and reported. RESULTS: 229 patients were screened. 177 received at least one dose of vardenafil and were included in the safety analysis. Mean age was 54.4 years old. Etiology of ED was organic or mixed in 77% of the patients. Erectile function domain of the IIEF changed from a basal mean score of 14.8 to 25.5 at the end of the study. 80.5% of the patients reported erections of rigidity and duration enough for satisfactory sexual intercourse and 93.3% improved their erections at the end of the study. Adverse events were mild to moderate and the most common were headache, dyspepsia, rhinitis and facial flushing. The drop out rate due to adverse events was 1.7%. CONCLUSIONS: This multicenter study confirms the high efficacy of this new phosphodiesterase type 5 inhibitor, vardenafil. There was a low rate of discontinuations due to adverse events and a favorable safety profile. The results of this study are similar to the results of other studies conducted in other parts of the world.
