Rationale & Objective: There are several well-known anatomical and physiological changes during pregnancy that could contribute to kidney stone formation, but evidence that they increase the risk of kidney stones during pregnancy is lacking. We determined whether there was an increased risk of a first-time symptomatic kidney stone during and after pregnancy.

Study Design: A population-based matched case-control study.

Introduction: Urolithiasis during pregnancy is an important health concern that can affect maternal and foetal health. If left untreated, it can cause obstetric complications, such as spontaneous abortion and preterm delivery. In this study, we aimed to evaluate urolithiasis and its treatment in pregnant women.

To evaluate the safety and efficacy of ultrasound (US) and primary ureteroscopy (URS) in the management of symptomatic obstructive ureteric stones during pregnancy. A prospective multicenter study was performed between June 2013 and December 2019, including all consecutive pregnant patients admitted to three urology centers with intractable renal colic with obstructed ureter secondary to obstructive ureteral calculi. Color Doppler ultrasound was used to evaluate renal Resistive Index (RI) and ureter jet.

Purpose: The aim of this study is to determine the proportion of maternal hydronephrosis and symptomatic cases requiring treatment in pregnant women without ureteral stones and the characteristics of these cases.

Materials And Methods: Between February 2018 and April 2019, all pregnant women followed for pregnancy in obstetrics and outpatient policlinic were evaluated prospectively. Maternal hydronephrosis rate, degree of hydronephrosis and side, symptomatic hydronephrosis rate, maximum renal anteroposterior diameter of renal pelvis and visual analogue scale were detected.

The obstructed hemivagina and ipsilateral renal agenesis (OHVIRA) syndrome, a rare Mullerian duct anomaly, is a triad of uterine anomalies with ipsilateral renal agenesis and obstructed hemivagina. The aetiopathogenesis of this developmental anomaly is debatable, with several theories being postulated to explain its occurrence. We report two cases of this rare syndrome which were detected on imaging done for unrelated reasons.

Background: Renal stones are a common cause of non-obstetrical abdominal pain in pregnant women. Though the management of renal stones in pregnancy is challenging, it remains unclear how the incidence of kidney stones may affect the course of pregnancy and delivery.

Objective: To determine the incidence of renal stones in pregnancy and its impact on adverse obstetrical outcomes.

Introduction: Medical Expulsive Treatment (MET) for ureteral stones has been questioned for the last few years.

Objectives: The main goal of our study is to define the indications of MET, the different drugs that are used and their effectiveness and to propose a follow-up strategy. Secondary objectives include the effectiveness of MET in some special subgroups such as pregnant women and children and to assess aspects of MET cost-effectiveness compared with other options for ureteral lithiasis treatment (ureterorenoscopy or extracorporeal shock wave lithotripsy).

Imaging in urolithiasis has a wide group of techniques, with different characteristics, limitations, and indications, which together allow the management of this prevalent pathology. Plain abdominal radiography and ultrasound are very accessible and in expensive techniques that combined present an acceptable sensitivity and specificity. They are widely used for monitoring the evolution of stone disease and for evaluation after treatments (surgery or SWL).

Familial disease history and fur color type are associated with urinary tract disease in farmed mink (Neovison vison).

Mink urinary tract disease (MUTD) and mink fatty liver disease (MFLD) constitute two important disease entities in the mink production associated with sudden mortality and economic loss. Genetic factors or heritability of the diseases have not previously been investigated. Since mortality associated with MUTD and MFLD mainly occurs in the young immature mink, a potential genetic predisposition would rarely be passed on by the mink itself but potentially by relatives.

Objectives: To investigate the acid-base status of sick goats using the simplified strong ion difference (sSID) approach, to establish the quantitative contribution of sSID variables to changes in blood pH and HCO and to determine whether clinical, acid-base, and biochemical variables on admission are associated with the mortality of sick goats.

Animals: One hundred forty-three sick goats.

Methods: Retrospective study.

Objectives: To assess the feasibility of conducting a randomised controlled trial (RCT) to assess whether avoiding ureteric drainage is superior to performing ureteric drainage after Uncomplicated Ureteroscopy and/or Flexible Ureterorenoscopy (URS/FURS) treatment of a urinary tract stone in improving patient reported outcome measures (PROMs) and 30-day unplanned readmission rates. A secondary objective was to understand current practice of urologists regarding ureteric drainage after uncomplicated URS/FURS (UU).

Material And Methods: We undertook an online survey of urologists, circulated amongst members of international urological societies and through social media platforms.

Objective: Urinary Tract Infections (UTIs) due to ureteral catheters has been frequently seen. The risk factors of this include both timing and those of the female gender. However, the association of Acute Pyelonephritis (APN) with use of ureteral DJ stents has rarely been investigated.

Background: The contemporary prevalence and trends of kidney stones are not clear.

Objective: To evaluate the gender-specific prevalence and trends in kidney stones among the US population.

Design, Setting, And Participants: Data on self-reported history of kidney stones from 34 749 participants aged ≥20 yr from the National Health and Nutrition Examination Survey (NHANES) were analyzed.

Objectives: To review the literature regarding the epidemiology of stone disease and develop a management algorithm based on current evidence and societal guidelines.

Methods: A structured literature review was performed to determine highest quality of evidence guiding care for pregnant patients with symptomatic nephrolithiasis. PUBMED and EMBASE databases were searched using terms "pregnancy," "nephrolithiasis," or "pregnancy" and "renal colic" alone and in combination with "stone", "kidney stone," "ultrasound," "MRI," "CT," "percutaneous nephrostomy," "ureteral stent," or "ureteroscopy.

Objective: To compare percutaneous nephrostomy tube versus JJ stent as an initial urinary drainage procedure in kidney stone patients presenting with acute kidney injury.

Methods: Between January 2017 and January 2019, 143 patients with acute kidney injury secondary to obstructive kidney stone were prospectively randomized into the percutaneous nephrostomy tube group (71 patients) and JJ stent group (72 patients) at Beni-Suef University Hospital, Beni-Suef, Egypt. Exclusion criteria included candidates for acute dialysis, fever (>38°C), pyonephrosis, pregnancy and uncontrolled coagulopathy.

To investigate risk factors associated with urinary tract infection (UTI), following ureteral stenting, for patients with renal colic during pregnancy. Patients with renal colic during pregnancy who underwent ureteral stenting in The First Affiliated Hospital of Guangzhou Medical University between 2009 and 2019 were examined retrospectively. Ureteral stenting patients who had UTIs after hospital discharge and before delivery were classified as the infected group.

Article Synopsis
  • * Researchers reviewed ultrasound results from 129 pregnant patients, comparing the effectiveness of transvaginal versus transabdominal ultrasound in identifying stones and related issues like hydronephrosis.
  • * Findings revealed that transvaginal ultrasound was significantly more effective, detecting 94% of distal stones compared to only 29% with transabdominal ultrasound, and also showed higher rates of hydronephrosis and elevated resistive indices in patients with detected stones.

BACKGROUND Urine pregnancy tests are usually performed by women at home and also by healthcare professionals. However, there are several conditions that may cause a false-positive urine pregnancy test, including trophoblast tumors, malignancy, nephrotic syndrome, adenomyosis, tubo-ovarian abscess, and paraneoplastic syndromes. A case is presented of a false-positive urine pregnancy test in a 28-year-old woman with a history of tubal ligation, who had a delayed diagnosis of obstructive pyelonephritis due to renal calculus.
