Postvoid Residual Volume Correlates With Bladder Outlet Obstruction and Not With Detrusor Contraction Strength Parameters in Women: A Matched Case-Control Study.

Purpose: To compare voiding parameters in women with and without increased postvoid residual (PVR) volume, to correlate these parameters with PVR volume and PVR percentage, and to describe their ability to predict an increased PVR volume.

Patients with spinal cord disorders and with abdominal straining during voiding (abdominal pressure ≥10 cm H2O over baseline at maximum flow rate [Qmax]) were excluded.

[ROC curves: general characteristics and their usefulness in clinical practice].

The use of diagnostic tests to determine the presence or absence of a disease is essential in clinical practice. The results of a diagnostic test may correspond to numerical estimates that require quantitative reference parameters to be transferred to a dichotomous interpretation as normal or abnormal and thus implement actions for the care of a condition or disease. For example, in the diagnosis of anemia it is necessary to define a cut-off point for the hemoglobin variable and create two categories that distinguish the presence or absence of anemia.

[Interobserver agreement in the diagnosis of bladder outlet obstruction in women].

Background: The diagnosis of bladder outlet obstruction (BOO) in women is a challenge for functional urology. In Mexico there are few data that report the prevalence of OTSV in women, being up to 24% in a group of patients.

Objective: The aim of this study is to compare six different definitions of bladder outlet obstruction and evaluate the interobserver agreement in an educational setting.

[Clinician and researcher at the time. Is it possible?].

Research in clinical practice arises as a constant need for improvement to provide better care to patients, train better human resources and make a daily reflection on the amount of scientific information we receive every day. We want to reflect on how the Centro de Adiestramiento en Investigación Clínica (CAIC) from our healthcare activity changed our practice.

[The relevance and irrelevance of charts in clinical research].

Charts are a visual aid that is used in articles in order to highlight the results of an investigation. They allow illustrating the results with the purpose of making them clearer. Charts, just like statistical tests, are selected based on the objective of the study, the types of variable, and the statistical analyzes to be illustrated.

Is there a role for sacral neuromodulation in patients with neurogenic lower urinary tract dysfunction?

Purpose: To review current literature regarding sacral neuromodulation (SNM) for neurogenic lower urinary tract dysfunction (NLUTD) focused on indications, barriers and latest technological developments.

Material And Methods: A PubMed database search was performed in April 2020, focusing on SNM and various neuro-urological conditions.

Results: SNM has been increasingly indicated for lower urinary tract dysfunction (LUTD) in neuro-urological patients.

[Lower urinary tract symptoms in medical residents as reflection of a stressful work environment.].

Objective: To determine if the presence of moderate to severe lower urinary tract symptoms in medical resident are associated with workplace bullying.

Material And Methods: Cross-sectional study conducted in medical residents. Moderate to severe lower urinary tract symptoms were defined as greater than 8 points on the International Prostate Symptom Score.

Factores predictores del estado libre de cálculos en la primera ureteroscopia flexible con litotricia láser.

Introduction: Flexible ureteroscopy and laser fragmentation (FURSL) is a minimally invasive modality for surgical treatment of renal stones. Inadequate selection of patients for this treatment generates a cost-effectiveness unbalance.

Objective: To know the stone-free rate predictors in a single surgical time in patients undergoing FURSL.

[Tasa libre de litos sin complicación mayor como definición de éxito en nefrolitotomía percutánea].

Introduction: Success in percutaneous nephrolithotomy (PCNL) is defined as a stone-free status; however, major complications are highly common and have been reported as a secondary outcome.

Objective: To propose a new definition of PCNL success that comprises a stone free rate without major complications and a risk scale to predict this outcome.

Methods: Historical cohort of patients undergoing PCNL.

Rearrangement of the Guy's stone score improves prediction of stone-free rate after percutaneous nephrolithotomy.

Objective: We propose a modification of the original Guy's Stone Score (GSS) to hold on 20 % of prognostic discrimination among groups which makes this score a more reliable resource for risk assessment in patients undergoing percutaneous nephrolithotomy (PCNL).

Material And Methods: Historical cohort of 126 patients undergoing PCNL from December 2010 to November 2014 was included in the survey. Every patient was classified according to the original GSS.
