X-ray free Percutaneous Nephrolithotomy (PCNL) with Alken Telescopic Metal Dilator for large stone in horseshoe kidney: A case report.

Percutaneous Nephrolithotomy (PCNL) has been shown as a safe and effective method for treating nephrolithiasis in horseshoe kidney patients. We report the first X-ray Free PCNL with Alken Telescopic Metal Dilator (ATMD) in horseshoe kidney. A 58-Year-Old female was diagnosed with left large staghorn stone and horseshoe kidney treated with X-ray Free PCNL with ATMD. X-ray Free PCNL with ATMD is safe and effective nephrolithiasis lithotripsy for staghorn stone in Horseshoe Kidney. This technique is the first of its kind and possibly has become an excellent alternative for urological centers without access to fluoroscopy.

Clinical parameters as predictors for sperm retrieval success in azoospermia: experience from Indonesia.

Background: Azoospermia is the most severe type of male infertility. This study aimed to identify useful clinical parameters to predict sperm retrieval success. This could assist clinicians in accurately diagnosing and treating patients based on the individual clinical parameters of patients. Methods: A retrospective cohort study was performed involving 517 patients with azoospermia who underwent sperm retrieval in Jakarta, Indonesia, between January 2010 and April 2023. Clinical evaluation and scrotal ultrasound, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were evaluated before surgery. Multivariate analyses were conducted to determine clinical parameters that could predict overall sperm retrieval success. Further subgroup analysis was performed to determine the factors that the diagnosis of non-obstructive azoospermia (NOA) diagnosis and sperm retrieval success among patients with NOA. Results: A total of 2,987 infertile men attended our clinic. Men with azoospermia (n=517) who met the inclusion criteria and did not fulfil any exclusion criteria were included in the study. The overall sperm retrieval success was 47.58%. Logistic regression revealed that FSH 7.76 mIU/mL (sensitivity: 60.1%, specificity: 63.3%, p<0.001); longest testicular axis length 3.89 cm (sensitivity: 33.6%, specificity: 41.6%); and varicocele (p<0.001) were independent factors for overall sperm retrieval. The FSH cutoff of 7.45 mIU/mL (sensitivity: 31.3%, specificity: 37.7%, p<0,001); longest testicular axis length 3.85 cm (sensitivity: 76.7%, specificity: 65.4%, p<0.001); and varicocele (p<0.001) were independent factors for NOA diagnosis. Varicocele was the only clinical parameter that significantly predicted the success of sperm retrieval in patients with NOA. Conclusions: FSH, LH, longest testicular axis, and varicocele are among the clinical parameters that are useful for predicting overall sperm retrieval success and NOA diagnosis. However, varicocele is the only clinical parameter that significantly predicts sperm retrieval success in patients with NOA. High-quality studies are required to assess the other predictors of sperm retrieval success.

Risk factor, diagnosis, and current treatment of H. pylori Infection in Indonesia: A Literature Review.

Helicobacter pylori (H. pylori) infection has become an emerging problem in Indonesia despite its relatively low prevalence as opposed to other Southeast Asian and Asian countries. Strains containing less virulent genotypes predominantly found in Indonesia is suggested to be the rationale for why the disease prevalence, as well as its gastric cancer complication, remain inferior in respect of neighboring counterparts. Although endoscopic evaluation is still necessary to determine the gastric mucosal status of those infected with H. pylori, the infection itself can be easily diagnosed with test-and-treat strategy especially in areas with limited resources. Several findings revealed high rates of antibiotic resistance varying among Indonesian regions and ethnicities, suggesting that triple therapy regimen may not be suitable for all population. Whereas treatment should be based on the pattern of resistance in respected region, novel regimens involving furazolidone, rifabutin, and sitafloxacin are proposed as potential drugs of choice to eradicate H. pylori infection. In order to determine the adequate approach for H. pylori infection in Indonesia, further multicenter studies involving larger sample size should be conducted.
