Description: The Holmium: yttrium-aluminum-garnet (Ho:YAG) laser has become the gold-standard intracorporeal lithotripsy device since it was first introduced in the 1980’s. More recently, the Thulium Fiber Laser (TFL) was introduced into the clinical setting, with the potential to address some of the inherent limitations with Ho:YAG devices. In particular, early experience suggested the TFL provided enhanced dusting and fragmenting capabilities, less retropulsion and better stone free rates compared to the Ho:YAG laser. Relevance: Should the initial claims of the TFL’s better dusting properties be confirmed, this would be a significant advancement in the field. The ability to dust larger stones more rapidly could enhance the role of ureteroscopy and reduce the need for more invasive procedures. Conclusion: The initial experience with the TFL is promising and suggests an advantage over Ho:YAG laser lithotripsy. Properly conducted prospective randomized trials are required to further delineate the advantages, disadvantages and to optimize patient outcomes.

Aim: Our primary aim was to report the prevalence of recurrent stricture following primary pyeloplasty and the secondary treatment performed. The secondary aim was to identify the clinical or surgical factors related to recurrent ureteropelvic junction obstruction (UPJO). Materials and methods: A retrospective study was conducted on patients diagnosed with UPJO at the Hospital General de Mexico “Dr. Eduardo Liceaga”, between 2011-2019. Patients that underwent primary pyeloplasty, and developed recurrent UPJO, underwent secondary treatment, and had follow-up ³6 months were included in the study. A descriptive analysis was carried out. Results: A total of 52 patients underwent open or laparoscopic pyeloplasty as primary treatment and 6 of them (11.5%) presented with recurrent UPJO at 44 months (median). Two of those patients presented with a non-functioning kidney and underwent simple laparoscopic nephrectomy and the remaining 4 patients underwent transperitoneal laparoscopic redo pyeloplasty as secondary treatment. The mean age of the patients with recurrence was 46 years, their mean BMI was 32.57±5 kg/m2, and two of them had urinary diversion prior to the primary pyeloplasty. Surgery duration was longer for laparoscopic redo pyeloplasty versus primary pyeloplasty (192 minutes versus 113 minutes) and intraoperative bleeding was similar (52cc versus 52.9cc). The surgical and histologic finding in laparoscopic redo pyeloplasty was peri-ureteral fibrosis. No aberrant vessels were found. Stricture was longer than 15 mm in the patients that underwent laparoscopic redo pyeloplasty (n=4). Obesity, lithiasis, and stricture length >15mm were more frequent in the patients with recurrence. Conclusions: The prevalence of UPJO in our study population was 11.5%, which concurs with international parameters. Laparoscopic redo pyeloplasty is a useful tool in cases of UPJO.

ObjectiveTo determine the prevalence of ED and associated risk factors among young Mexicans between 18 and 40 years of age.MethodsAn observational, cross-sectional, descriptive and analytic study was conducted. Data collection was achieved through a questionnaire. Participants completed the Urologic Health Survey for Men and the International Index of Erectile Function (IIEF-5) questionnaire. The study also included sociodemographic, clinical, and sexual behavior variables.ResultsOf the 373 questionnaires filled out, only 160 were answered completely and used for the analysis. The mean age was 25.59±5.45 years. The prevalence of ED was 33.7% (mild 17.5%, mild-to-moderate 8.1%, moderate 6.3%, and severe 1.9%). The mean score for non-ED males was 24.38±0.94 versus 15.41±4.81 in the ED group. Univariate analysis showed a significant difference in the items of age (p

Introduction Orgasmic dysfunction (OD) is defined as the inability to achieve an orgasm, markedly diminished intensity of orgasmic sensations, or marked delay of orgasm during any kind of sexual stimulation. OD definition and method of diagnosis vary widely across studies. Aim The aim of this study was to identify the prevalence and risk factors that predispose Mexican women to OD. Methods A representative sample of women from Mexico City was surveyed using an online website. Women between 18 to 40 years old were selected, and the orgasm domain from the Female Sexual Function Index was used to identify OD. A cutoff point was calculated using a construct with a histogram and calculated median. A univariate and multivariate analysis was conducted to examine the relationship between potential risk factors and sexual function. Main Outcome Measures OD prevalence; significant risk factors on multivariate analysis. Results OD prevalence was 18.3%. Univariate analysis showed younger age (P = 0.01), lower degree of education (P = 0.02), single marital status (P = 0.038), and dissatisfaction with the thickness and/or size of partner's penis (P = 0.01) as significant variables related to OD. In multivariate analysis, younger age (P = 0.01) and dissatisfaction with the thickness/size of partner's penis (hazard ratio 3.04, P = 0.01) remained significant. Conclusion OD is a prevalent alteration in young women. Marital status, education, and dissatisfaction with thickness/size of partner's penis are definitely related variables.
