Introduction: Percutaneous nephrolithotomy (PCNL) is the minimally invasive procedure of choice for the treatment of large and/or complex nephrolithiasis. Migration of residual fragments (RFs) into the ureter after PCNL is presumed to be uncommon. However, should associated stone-related events (SREs) occur, ancillary procedures may be required.

Methods: A retrospective review of donor-to-recipient pairs undergoing living donor kidney transplantation was done. They were classified according to gender match as: male-to-male, female-to-female, male-to-female, and female-to-male.
Problem: The effect of donor/recipient age disparity on living-donor renal graft function is controversial. The objective of this study is to find new clinical predictors of renal graft function and evaluate the effect of donor/recipient age disparity in our series.
Methods: A retrospective review of our institutional renal transplantation database was performed.
The correlation between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED): results from a survey in males from Mexico City (MexiLUTS).

Introduction: ED and LUTS affect a high proportion of male population. Although Hispanics are suspected to have a higher risk of experiencing LUTS, detailed information on its frequency and association with ED in this population is scarce.
Objective: To determine the frequency of LUTS and ED, and its correlation in Mexican males.
Practice patterns and choice of technological instruments in PCNL are not always standardized. There are no previous reports on the PCNL practice tendencies and patterns in Latin America. The aim of the study is to describe the current practice patterns of PCNL among the members of the Mexican Society of Urology ("Sociedad Mexicana de Urologia").

Methods: We performed a retrospective analysis of non-seminomatous testicular tumours and concurrent retroperitoneal lymph node metastases, which received chemotherapy and had computed tomography scans before and after treatment. Volumetric analysis and RECIST criteria were used to calculate response rates.
Article Synopsis
- The study aimed to evaluate how common erectile dysfunction (ED) is among HIV patients in a clinic in Mexico City and identify associated risk factors.
- About 65.1% of the 109 participants, averaging 39.9 years old, reported experiencing ED, with dyslipidemia being the only significant risk factor identified.
- The findings suggest that ED is prevalent in HIV patients, highlighting the need to consider dyslipidemia as a key risk factor when assessing ED in this population.
Article Synopsis
- The report discusses a unique case of a giant multicystic cystadenoma originating from Cowper's glands in a healthy 41-year-old man who experienced acute urinary retention and had a perineal mass.
- Imaging techniques confirmed the presence of a multicystic tumor, which was successfully removed through en bloc excision, with histological analysis indicating the tumor's benign nature.
- This case highlights the need to consider cystadenomas of Cowper's glands as a potential diagnosis for pelvic cystic tumors, suggesting that surgical excision can both confirm the diagnosis and serve as a curative treatment.
